A hperlink for a header file in a c/c++ project

Hi,
How can I configure a c/c++ project, so that the #include directive will be
followed by a header file name with a hyperlinlk (so that clicking on it
will cause the editor to jump to that header file ? )
Mark

Mark,
I guess you are using makefile-based project (i.e. "project from existing sources"), right?
In this case you should somehow "explain" the built-in parser where to search your include files. There are two ways of doing that:
1) Manual: in Project View context menu:
Project Properties -> Parser Configuration -> C Compiler (or C++ Compiler) -> Include Directories
2) Automatic: in Project View context menu, select "Configure Code Assistance"
To use this, you have to first build your project with debugging information. The "Configure Code Assistance" mode uses this information to correctly determine what include paths were used.

Vladimir

Header file entry for Text Channel

I have taken an ASCII Text Data file, read the file, and created a Header File, then saved the data into a binary file. This is my attempt to speed up the loading of the text file. One of the columns is a text column, containing a flag for the state of the test. I can not figure out how to define the column as a Text Column in the Header File. If I define it as a numeric column, it returns an error for every entry in the data file. Normal (one of the states) is not a Numeric Value.
The script file(s) I am using is a modification of a script listed on this board by Brad Turpin ( TimeSlice DAT Hdr Create.zip ) The only thing I have changed is the Test for the Channel Name to see if it contains on of 3 states. If Date is present in the Channel Name , it changes the field to a Time channel, if the channel contains Relay it changes it to a Text channel (which doesn't work), else the Channel is a Numeric.
There must be a way to define a Text Channel in a Header File. I hope someone can show me the way.
Thanks

Hello Bill!
The DAT format was never able to store text channels (TDM is able today). Please refer to the DAT format description on your DIAdem CD or in this post.
Your idea to convert it to a numeric value is the right way. The error message must come out of the header. Do you convert all properties to numeric values? See page 4-6 and following in the header description or search for the word 'normal' in the created header file.

UFL Header Files in Crystal XI R2

Hi,
I'm looking for the header files:-
crdll.h
crdates.h
crdates.c
ufdll.h
ufuser.h
ufmain.h
uffuncs.h
ufmain.c
ufjob.h
ufjob.c
Described in the technical reference guide, but I'm unable to find them?
Alternatively is there a way to implement UF5SaveState & UF5RestoreState in a COM extension?

CR XI R2 is end of life. There are no files available any more so it can be closed.
If they are not include in these 2 final installers then no option:

Including Header files

Hi
Am a mainframe guy and new to these stuffs.
Now ,I want to compile a C++ program in Sunstudio.
My question is how & where to add the header files ?
What is the extension to be used for the header files ?
Please someone help me in this regard.

[I had replied to this yesterday but it didn't appear to show up in the thread]
The header file is added to the 'Header files' in the same project For Sun Studio, I am pretty sure that the header files listed in the project
is not used by the compiler to find the header files.
That list of header files is merely a convience for the programmer
as a reference and to quickly find and open header files used in the project.
You need to tell the IDE which directories to search for header files
(that are not standard header files)
I am presuming that the header file(s) the compiler is complaining about is not a standard library header file,
but instead is a header file associated with the source code you are compiling or are associated with
a 3rd party library required by the program.
The #include semantics, as ralphw mentioned, can be a little complex.
As a quick follow up to ralphw's response
generally #includes of the form
#include "foo.h"
indicates that the header file is in the same directory as your project source files.
Normally the compiler can find this file with some simple seach heuristics so
I suspect the offending include line is of the form:
#include <foo.h>
The <> brackets indicates that the header file is in a directory to be specified
in one of the listed include directories.
Include directories may be intrinsic to the compiler implementation
such as standard libraries and/or libraries added by the compiler vendor;
or they may be header files for 3rd party libraries or your own libraries
stored in some directory other than the application program you are compiling.
For 3rd party libraries or your own libraries, provide a list of
directories to seach for included header files.
for command line mode, in almost all c/c++ compilers these directories are listed with
the -I command line argument.
In SunStudio 12, you list the include directories in
your project properties / Parse configuration / Sun C++ compiler / General / Preprocessor definitions
If you have further questions on this, it would be helpful to know
if you are attempting to compile some preexisting code
or are you creating code from scratch.
(It sounds like you are compiling preexisting code that
presumably has been compiled correctly in some other implementation
and are trying to port it to Sun Studio.
If this is the case, it sounds like you simply need to add the
path of the directory containing the offending header file to
this list of include directories.)
It would also be helpful to know the fully qualified
file name of the offending .h file,
and the form of the #include line in the file that is being compiled.
If the #include line is of the form
#include <dir/foo.h> then you need to add the
path of the 'dir' parent directory to the include directories list.

Place function in header file?

Hello, again.
Suppose I have a piece of code that I know I am going to be using very often. Obviously, the logical thing to do is place it in a function. And, suppose that I know I'm going to be calling that function often, and in a lot of different projects. How can I best make it so that I don't have to declare and define the function in every file in every project that I want to use this function in?
Would I place the function in a header file, and then use the #include preprocessor directive to include the .h file in every file I want to use the function in? If so, why couldn't I just store the function in a .c/.cpp file? What does a header file offer over a .c or .cpp file -- why use one over the other?
Also, where do I go to create the header file? If I go to File > New File and select header file, then it creates it as a file within the project that I have open at that moment, and I'm going to want to use the file in other projects. Is there somewhere I can save the header file outside of any specific project, so that I can include it in any project I want?
Thanks.

So, technically, I could define the entire function in the header file, even without declaring it as inline, and I wouldn't have to define it in a source file?
Nope. You'll get linker errors, or at least warnings, about the function being defined twice.
1.) Why define it in a source file in the first place? Why not always define it in the header file? I can imagine there's obviously a very good reason for this -- I'm just curious what it is.
Code bloat and the sheer inefficiency of having the same code duplicated everywhere.
2.) You said that if the function is defined in the header file instead of a source file then it is treated as a macro and the whole function is picked up and dropped in your code wherever it is called. This sounds like the same thing as an inline function, so if you did define the entire function in the header file, what would be the difference between defining the whole thing in the header file using the inline keyword, versus defining the whole thing in the header file without the inline keyword?
Well, it is an inline function. You must use the inline keyword.
3.) Finally, if I did decide to define the entire function in the header file and not use a source file, would I still need to write the function signature as well, or just the definition?
Just the definition.

Concerning header files and include files

I presently have a site I created in Frontpage 2003, Gunshows-USA.com. It has seperate pages for each state and month. I had a header file called head.shmtl that I included on each page. This allowed me to create one file and reuse it on 50 different pages. I was also able to place it on the page in such a way that I could include it under the Title of the page and even iinsert an indiviual banner above the header.shtml. Will I be able to do basically the same thing with Dreamwaver 5.5s header and footer function? If so, is there anything special I need to be aware of?

I guess I didn't quite explain myself as well as I should have.
1st I had used include files on my site for a header and a footer but the site broke and when I got it back up it was necessary to load code for each header file to each page to get it to appear. I am not presently using include files on the site. The site was created in FrontPage 2003 and I intend on migrating it to Dreamweaver as soon as I know a little more about what I'm doing with DW
2nd. When I had the include files working I did NOT have to change everything on every page when I wanted to change something in the header or footer. The way I have it set up now I do.
3rd. Going through different tutorials books, etc I see that I can create a file with a header, a body, and a footer from the templates that are built into the program. An example is the 3 column fixed, header and footer. My question is, if I use this layout will that layout follow throughout the site and will I be able to basically do the same as I did when I was using includes? Will a change to the header file change every header file?
4th. Can I position the header file sot that it has space above it. Or another words can I have the header file appear in the middle of the page?
5th. Is if possible to have more than one header or footer file and be able to call the one I want or use all one after another?

Creating a header for a .CSV file

Hi,
I have looked through the forums and cannot find a solution for creating a header for a csv file. I am using Labview 8.2. I want a label for each column at the top of the file and then I will append new rows to the file as the data is collected. An example of what I am looking for is attached.
It would also be nice to have the labels descending in the first column, pretty much a transposed version of what was described above.
Thanks,
Gary

Thank you very much. That worked well.
If i wanted to transpose the data how would I do that? I can get the header to be vertical, but I cant get the data to append to the 2nd column , and then the third and so on with the data descending from top to bottom. I attached an example of what I might want the file to look like. Each column would be added one at a time.

Ther are PARAMETER LIST DISCREPANCIES in the help file vs the NIDAQ.H header file for GPCTR_Read_Buffer...

PROBLEM: The function help file contains documentation for using GPCTR_Read_Buffer with 7 parmeters in the parameter list. The NADAQ.H Header file contains 8 parameters in the function declaration. Which is right? What is the correct parameter list and can an example be provided that shows how to use the function correctly? I am currently using DAQ ver 6.92 and a 6602 Counter Timer board in a buffered start/stop or ND_BUFFERED_TWO_SIGNAL_EDGE_SEPARATION_MSR application.

Thanks for the response Filipe, I'll let you know how it goes. I only went into the header file because example code provided by NI ... paste ...
iStatus = GPCTR_Read_Buffer(iDevice, ulGpctrNum, ND_READ_MARK, ulReadOffset, ulNumPtsToRead, ulTimeOut, &ulNumPtsRead, pulReadBuf);
showed use of 8 parameters - in agreement with the header file and in disagreement with the on-line help file function documentation.

What's This Help not working for one entry in each header file

I have a large RoboHelp project that I have imported into Version 8 from a previous version. Prior to the import into Version 8, all of the What's This Help in the project was working perfectly; now, post-import, I have a problem.
Firstly, some background information.
My project contains a large number of individual header (.H) files, one for each dialog within the software. These header files, which have been generated and provided by our developers, contain one entry for each field on the dialog to which the header file relates. The header files are all contained within a \HTML Topics\Fields\ folder (going from the root of my Help project).
Each header file has a corresponding text (.TXT) file. These text files contain entries that correspond to the entries in the relevant header file. The text files are also contained within the \HTML Topics\Fields\ folder.
Below is an example of the contents of a header file:
#define IDH_HIERARCHY_APPEARANCE_HIEARCHY_LIST          16811
#define IDH_HIERARCHY_APPEARANCE_ADD_APPEARANCE         16812
#define IDH_HIERARCHY_APPEARANCE_REMOVE_APPEARANCE      16813
Below is the contents of the corresponding text file:
.topic IDH_HIERARCHY_APPEARANCE_ADD_APPEARANCE
Click this button to add a new row of hierarchical appearance settings to the grid.
.topic IDH_HIERARCHY_APPEARANCE_HIEARCHY_LIST
Use this grid to define hierarchy appearance settings. Each row in the grid represents a level of the hierarchy. For example, the appearance settings you define for the first row apply to the top level of hierarchy, the settings you define for the second row apply to the second level, and so on.
.topic IDH_HIERARCHY_APPEARANCE_REMOVE_APPEARANCE
Click this button to delete the selected row of hierarchical appearance settings from the grid.
The What's This Help that was part of the original project still works perfectly. However, after upgrading the project to RoboHelp Version 8, I have had to update the project to reflect changes to the software. As part of this work, I have imported some new header files and updated some existing ones - and edited the corresponding text files accordingly.
The What's This Help that is covered by the header files that I have imported since the upgrade to RoboHelp Version 8 does not work correctly; in each case, the What's This Help does not work for whichever field appears at the top of the appropriate text file. The position of the entry in the corresponding header file does not make a difference.
If I manually edit a text file to move a different entry to the top then recompile the Help project, the What's This Help does not work for the field that now appears at the top of the text file - and the What's This Help for the field that used to appear at the top of the text file now works.
I've tried everything I can think of to fix this, but nothing has worked. It seems as if there is a problem in the way RoboHelp is compiling the header and text files.
If I use Microsoft HTML Help Workshop to decompile the CHM file, then view the contents of the resulting, decompiled text files, the affected files appear as follows:
.topic IDH_HIERARCHY_APPEARANCE_ADD_APPEARANCE
Click this button to add a new row of hierarchical appearance settings to the grid.
.topic 16811
Use this grid to define hierarchy appearance settings. Each row in the grid represents a level of the hierarchy. For example, the appearance settings you define for the first row apply to the top level of hierarchy, the settings you define for the second row apply
to the second level, and so on.
.topic 16813
Click this button to delete the selected row of hierarchical appearance settings from the grid.
Note how the entry at the top - which relates to the What's This Help that doesn't work - appears differently to the other entries which do work. The name of the ID appears after ".topic" rather than the appropriate ID number.
Any help that anyone can provide me with would be very much appreciated.
Thank you,
Mark

Its working now. We just kept trying to reinstall the tools and restarting indesign. On the 4th time the buttons started working. I can't explain why it finally worked, just that it is working now.

[SOLVED] Location of header files (for vmware tools)

Attempting to install VMWare Tools (http://www.vmware.com/support/ws5/doc/w … linux.html) for my Archlinux guest, encountered this question:
What is the location of the directory of C header files that match your running
kernel? [/usr/src/linux/include]
I found a few old posts saying to use the AUR package, but I can't per my divisions linux server policies (no non-official repositories). Are these included by default, or do I need to get them via some package? Is this kernels-26-headers package, or similar?
Last edited by Intrepidus (2010-10-25 22:38:07)

Thanks, that got me a bit farther than before. I've now gone from that error to this error:
The directory of kernel headers (version @@VMWARE@@ UTS_RELEASE) does not match your running kernel (version 2.6.35-ARCH). Even if the module were to compile successfully, it would not load into the running kernel.
This was after pointing it to /usr/src/linux-2.6.35-ARCH/include. Any ideas what the story is now?
EDIT: Had to copy utsrelease.h and autoconf.h to version.h and autoconf.h, respectively, to /usr/src/linux-2.6.35-ARCH/include/linux.

Gettin header files for embedded sql

Sir,
iam acutally looking for header files needed used in embedded sql,which is used pro c* compiler .So i request you to send me a link of these files,as iam tying to learn this topic.these files are not generally available in a genaral C compiler.
So please send me reply about this and also if this particular language/techn is still being used which may help me to improve my knowledge

I am not a Cobol programmer, but I worked several years a Pro*C programmer, this precompiler issue looks very similar to others I have several times faced, when I compiled a pro*C program on different platforms, the makefile had to be tailored to fit the particular platform paths. May be this is happening to you, you should verify the compilation script and ensure the required libraries are visible.

Can you give me some header file (in C or in VB) or maybe a list a functions and parameters of this labrarie.

Hi,
You will find a list of all functions which can be used in LV PDA applications.

Header file for GUI in CVI

Hi
        I have created the GUI by adding different controls. When I make some changes in that
xxx.uir file and save it, it automatically do the changes in xxx.h file.
But If want to #define the values for all the controls, how to do that.
For eg :
Autogenerated xxx.h file has
#define PANEL                                          1
#define PANEL_CHECKBOX_1                   2
#define PANEL_CHECKBOX_5                 3
#define PANEL_LED_1                              4
#define PANEL_CHECKBOX_2                  5
#define PANEL_CHECKBOX_3                 6
#define PANEL_LED_2                             7
#define PANEL_CHECKBOX_4                8
But I want to edit it like
#define PANEL                                          1
#define PANEL_CHECKBOX_1                   2
#define PANEL_CHECKBOX_2                   3
#define PANEL_CHECKBOX_3                   4
#define PANEL_CHECKBOX_4                   5
#define PANEL_CHECKBOX_5                   6
#define PANEL_LED_2                               11
#define PANEL_LED_1                              12
Is it possible to do that?
Please any one help me on this

Hi Nagraj,
The autogenerated gui header files should not be edited directly.
CVI assigns control IDs according to their tab order in the UIR panel.
To modify the tab order, activate the panel you want to edit and press Ctrl + T.
This opens a tab-order-editor where you can set the tab order simply by clicking the controls in that desired order.
After you save the file, the header gets refreshed with the new control IDs.
Hope this helps,
P.S: If you want to change these control IDs just to access them in a loop,
I suggest you to put the control IDs in an array and then use the for loop variable as the array's index.
e.g:
int i;
int ctrlArr[5] = {PANEL_RUN_BUTTON, PANEL_LED, PANEL_RING, PANEL_TABLE, PANEL_STOP_BUTTON};
for (i=0; i<5; i++)
// good
SetCtrlAttribute (panel, ctrlArr[i], ATTR_DIMMED, 0);
// bad
// SetCtrlAttribute (panel, i, ATTR_DIMMED, 0);

To calculate Header size for an audio file.

HI ALL
Iam displaying the wave form for an audio file opened(.wav, .au ...etc) and doing any edit operation (cut for example) my waveform is shown with extra header (bytes) added to this wave form, i want to get rid of this. That's why i want to calculate the Header Size, which i heard that header size is not constant for all the files(even same two .wav files).
Any Ideas will be appreciated.
Thanks

What is the meaing of the sysmbolic constant value in the header file for UIR file and how they are used

In labwindows after creating the uir then header file is create automatically. There it has define some symbolic constant. As examples of colview.h(from the examples of labwindows )
#define MAINPNL              1       /* callback function: MainPanelCB */
#define MAINPNL_RESULTS      2     /* control type: table, callback function: ResultTableCB */
#define MAINPNL_NEWTEST     3       /* control type: command, callback function: NewTestCB */
My question is how these values 1, 2 and 3 were selected and how they are used in programs ?
If anyone explains, it will be a great help.

When creating a UIR file, CVI editor takes care of assigning constants to the panels / controls you create in it.
The conceptual framework is the following (assuming to treat the file you have reported in your message):
- Within a single UIR file all panels have a unique ID, which is the one you pass to LoadPanel when loading a panel into memory. LoadPanel (0, "myfile.uir", MAINPNL); is then translated to panelHandle = LoadPanel (0, "myfile.uir", 1); , that is: "load the first panel in the uir file". The panel in memory is then assigned a handle, which is guaranted unique by the OS and saved in panelHandle variable
- Addressing a control in a panel is done e.g. using SetCtrlVal (panelHandle, MAINPNL_NEWTEST, xxx); , which again is translated to SetCtrlVal (panelHandle, 1, 3); that is: "Set control #3 in the panel identified by panelHandle to value xxx".
You must not modify the include file associated to the UIR as it is fully maintained by the IDE and is rewritten each time you save the UIR file.
That conceptual framework has some advantages and some caveats:
- You can load the same panel more then once in your program: each instance is independent from the others as each panel handle is unique; in some occasions it may be helpful, e.g. if you need to handle several identical equipments connected to your PC and you can load the same control panel for each unit connected maintaining each of them independent
- If the panel handle is wrong, the system does not warn you of this as it does not know of the symbolic names you are using; if you try that SetCtrlVal command with a wrong handle you are trying to manipulate a control on a panel different from the one you intend: supposing actual panel idientified by the handle has control #3 the maximum you can expect is that you receive an error in case you pass e.g. a string to a numeric, but if controls are of the same type you have no errors or warning at all! This is particularly important when addressing controls on pages of a tab control: each page is really a separate panel with its proper handle that you must retrieve with GetPanelhandleFromTabPage command before addressing the controls on it
Proud to use LW/CVI from 3.1 on.
