Reading DLL function and parameters from a header file

Hallo to everyone,
I am trying to find a cute way

Hello,
I think this is what you were asking in another stream. I don't think there is a way to do that. For examples of passing data to dlls given the naming convention variation across environments, check out the shipping example named Call DLL.vi, which will open other examples of using call library function nodes with a datatype you specify.
I hope this helps, and these suggestions are very welcome at our feedback site - click Contact NI at ni.com, and then the word "feedback" in the lower left corner to submit a product suggestion.

Are these functions and parameters used in DirectX 11.2?

Functions and parameters like WINAPI, hPrevInstance, hInstance , PSTR etc are used in DirectX 11.2?

This is the entry-point for a Windows desktop application (aka Win32 application) whatever the architecture it is running on (32-bit or 64-bit native).
int WINAPI wWinMain(_In_ HINSTANCE hInstance, _In_opt_ HINSTANCE hPrevInstance, _In_ LPWSTR lpCmdLine, _In_ int nCmdShow)
This is not used for Windows Store apps or Windows phone apps which instead use:
[Platform::MTAThread]
int main(Platform::Array<Platform::String^>^)
I suspect you are using this forum as it's the only one that mentions "DirectX" but you aren't writing a Windows Store app. You should take al look at the
Direct3D Win32 Game Visual Studio template for VS 2013 or this
tutorial for an example of how to set up a DirectX 11 device and swap chain for a Windows desktop application for 32-bit and 64-bit native.

How To... Execute Planning Functions and Sequences from MS Office Ribbon

Dear all,
I am working with a SAP how to paper, which is called:
How To... Execute Planning Functions and Sequences from MS Office Ribbon.
It is working absolutely fine and I am pretty satisfied, but as you probably know "Control the visibility of a button based on the visibility of a related crosstab: the button just disappears once the related crosstab is not located on the active sheet."
This means, when I insert different queries in different crosstabs, only one crosstab will have my own created ribbon. Is it also possible to set another specific ribbon with other buttons for another crosstab? Can I change the macro, included in the appendix of the how to paper, regarding this issue?
Thanks in advance!
Kind regards
Dominik Drebinger

Hey Martin,
thanks for your reply, but I solved the problem on my own. Unfortunately my colleague did not see that the crosstabs had to be defined differently.
Like this:
Label
Screentip
Msolmage name
Crosstab name
Copy Initial Aligned
Copy Initial Aligned
CacheListData
SAPCrosstab1
Copy Initial Aligned
Copy Initial Aligned
CacheListData
SAPCrosstab3
Copy Initial Aligned
Copy Initial Aligned
CacheListData
SAPCrosstab5
The macro, provided by the HowTo, is therefore working perfectly fine.
Thanks though
Dominik

How to read the date and time information of a file by labview

how to read the date and time information of a file by labview? for example, created time and modified time.
Solved!
Go to Solution.

if you need to know the last modification date of file:-
"Functions->File I/O->Advanced File Functions->File/Directory Info.vi"
This vi returns the value of file's last modification date. This is returned as U32 number. To see it in MM/DD/YY format you must create the indicator, right-click on it and select "Format & Precision" item from drop-down menu. Then select "Time and Date" format there.
Thanks as kudos only

How to read the 'full resolution composite' from a .psd file?

I'm working with 16-bit .psd files and have the "maximize compatibility" switch turned on in CS2. When a file is saved, a message box appears indicating that PS is generating a "full resolution composite." I'd guess this is stored in the .psd file somehow, because some of the 3rd party image viewers are able to display the image when the compatibility switch is used, but are unable to display the image otherwise.
My question is: how can I read this full resolution composite from the .psd file outside of Photoshop?
If this is the wrong forum to post this question, I'd appreciate it of you'd tell me a better place.
Thanks,
Dave H.

As you guess, it is stored in the PSD, but only with the Maximise Compatibility switch. Without that switch, a dummy image is stored which has the text "This layered Photoshop file was not saved with a composite image.", in English, German, Japanese and French.
My program
psdparse extracts each layer in an 8-bit file as a PNG, and the merged image for both 8- and 16-bit files. That link is to a Subversion repository containing source code.

HT4914 My pc has crashed and lost a considerable amount of music and videos from iTunes the files are still in iTunes but are empty, will iTunes Match restore my content over the cloud?

My pc has crashed and lost a considerable amount of music and videos from iTunes the files are still in iTunes but are empty, will iTunes Match restore my content over the cloud?

Hm ... I guess I can't edit the post above. Anyway, I seem to have solved it by ...
Quitting iTunes.
Going into Home / Music / iTunes, and renaming the file "iTunes Library.itl" to "iTunes Library (corrupt).itl".
Entering Time Machine, and restoring the "iTunes Library.itl" file from a few days ago. I went back two days, which seemed far enough back to be "before" the problem but not far enough back to have trouble with recent acquisitions.
Re-opening iTunes - and everything seemed to be back in order.
So that's fine for now. We'll see if the solution is stable.
Very, very tentative assignment of blame: I believe iTunes crashed earlier today after I'd synced photos from my iPhone to iPhoto, and then iTunes crashed while iPhoto was closing (and taking its sweet time doing so). If that was indeed the case, that's at least the second time in the past couple of months that trying to sync iPhone photos to iPhoto has caused me significant problems. (The last time led to 80% of my iPhone suddenly being occupied by "Other", and a full restore of the darn thing.)

Reading a PublicKey \ PrivateKey type from a txt file

Hi,
i want to read a PublicKey \ PrivateKey type from a txt file and input it into a method.
How can i read the data from the file while keeping or converting back to PublicKey \ PrivateKey type?
I'm working with the following:
generate = KeyPairGenerator.getInstance("ECDSA", "FlexiEC");
generate.initialize(ecParams, new SecureRandom());
KeyPair keyPair = generate.generateKeyPair();
............continues
**and then i write the keys to the a simple txt file.**
thanks!
Edited by: sk16 on Apr 8, 2010 10:03 PM

So, if i work with the two above is it ok, like:
generate = KeyPairGenerator.getInstance("ECDSA", "FlexiEC");
               generate.initialize(ecParams, new SecureRandom());
               KeyPair keyPair = generate.generateKeyPair();
               // Pub. and Priv. key objects.
               PublicKey publicKey = keyPair.getPublic();
               PrivateKey privateKey = keyPair.getPrivate();
               // Write keys to separate files.
               FileOutputStream fos = new FileOutputStream(publicKeyFile);
               fos.write(publicKey.getEncoded());
               fos.close();
               FileOutputStream fos1 = new FileOutputStream(privateKeyFile);
               fos1.write(privateKey.getEncoded());
               fos1.close();
and then for example>>>
DataInputStream in = new DataInputStream(
          new FileInputStream("publicKeyFile.txt"));
          byte[] encodedPublicKey = new byte[1024];
          in.read(encodedPublicKey);
          in.close();
          X509EncodedKeySpec encodedPublicKeySpec = new X509EncodedKeySpec(encodedPublicKey);
          KeyFactory keyFactory = KeyFactory.getInstance("ECDSA", "FlexiEC");
          publicKey = keyFactory.generatePublic(encodedPublicKeySpec);

Tdms-files: Is it possible to prevent LabVIEW and DIAdem from creating .tdms_index files?

Hello,
is it possible to prevent LabVIEW and DIAdem from creating .tdms_index files when opening/creating/editing a .tdms file?
I think I have no benefit from the .tdms_index files because our applications create a lot of little .tdms-files (repeat measurements). With the additional .tdms_index files we have unnecessary memory consumption and it takes longer for Windows to open the containing folder. Also it´s confusing when searching for a certain file.
Best Regards
Daniel
Solved!
Go to Solution.

Hi Baui,
I'm afraid there's a direct way to disable creating .tdms_index file now from LabVIEW and DIAdem. You can use TDMS Advacend API in LabVIEW, which doesn't create any index file, or you can just make some simple programming and delete the .tdms_index file after closing the TDMS file.
This is a request for a long time, we'll consider to add this feature for TDMS in future releases.

How to read a tab seperated data from a text file using utl_file

Hi,
How to read a tab seperated data from a text file using utl_file...
I know if we use UTL_FILE.get_line we can read the whole line...but i need to read the tab separated value separately.....
Thanks in advance...

I know if we use UTL_FILE.get_line we can read the whole line...but i need to read the tab separated value separately.....If it's a text file then UTL_FILE will only allow you to read it a line at a time. It is then up to you to split that string up (search for split string on this forum for methods) into it's individual components.
If the text file contains a standard structure on each line, i.e. it is a fixed delimited structure, then you could use external tables to read the data instead.

Reading and Writing from a text file at the same time

I know who to use the Scanner and PrintWriter to read from and write to a .txt file. But these are limited. How can I read and write at the same time? Such as open a file and change every third character or change every second word to something else and then write it back. I found this [http://java.sun.com/docs/books/tutorial/essential/io/|http://java.sun.com/docs/books/tutorial/essential/io/] but its a little over my head. Is this the only way to do it?

wrote:
You are using buffered reads and writes I would assume, right? Also, how do you think most programs handle this sort of thing? I don't believe I'm using buffering.
My code looks something like this
//...necessary imports
//then
Scanner inFile = new Scanner (new file("filename1.txt"));
PrintWriter outFile = new PrintWriter ("filename2.txt");
//then stuff like
int x = inFile.hasNextInt();
outFile.println(x);
camickr wrote:If you are changing the data "in place", that is none of the data in the file is shifted, then you can use a RandomAccessFile.
Otherwise, you've been given the answer above.What is RandomAccessFile? Is it what I have a link to? Basically what I do is I write a bunch of numbers to a txt file and then change the numbers I don't need anymore to 0. So say I had 0 1 2 3 4 5 6 7 etc. I would like to to open the txt file and change every second one to 0 so then I'd have only odd numbers and 0s.
I looked at the documentation for RandomAccessFile and it seems like it might be what I need.
Thankyou both for your help so far. I took a java course in high school and they only taught me one way to get data from text files and that is what I just showed you. So maybe this questions are really stupid. lol

Extracting username and password from security header

Hey all,
I'm writing a BPEL process that invokes two secured web services. One of them authenticates using Username Token and the other has a authenticate method in which the username and password are supplied as Strings. I have successfully propagated the credentials from the BPEL process to the web service using Username Token by doing the following:
1) I secured my BPEL process
2) I imported oasis-200401-wss-wssecurity-secext-1.0.xsd and from it created a variable of type Security
3) I added the security variable to the Header Variables for the BPEL process input
4) I added the security variable to the Input Header Variables for the web service's invoke operation
This worked fine. However, I need to be able to extract out the username and password and supply them as Strings to the authenticate method of the other web service. How can this be done? If it can't, what are some alternatives?
Environment:
JDeveloper 11.1.1.6.0
Thanks,
Bill

Hi Sri,
If I understand your steps correctly, I think the problem I'm having rests with the second step. I don't know how to get a hold of the username and password to assign to the local variables you mention. The BPEL process itself uses Username Token for authentication. These credentials need to be passed to the web services invoked within the BPEL process. If I assign the security header variable directly to the string output for the BPEL process, the string returned will be the complete XML security header, which includes the username and password. However, the security header variable itself doesn't expose the username and password directly. In other words, I can't expand the security header variable node in the dialog for editing the Assign operation and get to the username and password. I think one solution is to parse out the username and password from the complete XML security header using string operations (substring, index-within-string, etc). Also, regarding step 4, I'm not sure if passing the credentials in the header will work for this web service. I think the web service is expecting the credentials as parameters to its authenticate method.
Thanks,
Bill

How to pass a struct to a DLL function and accessing it in another VI

Hi friends,
                   I am new to labview. I need to create a demo program in labview ,for displaying image from our own image capturing system. We have a DLL ( build in VC++) containing functions for capturing image from our system. Now I need to create a VI library for some of functions in DLL and Create a Demo program using those created subvi library . I used "Call Function node" and created some of subvi's.
Some of our DLL functions need to pass struct pointers. Our function prototype will be similar to the following function.
__declspec(dllexport) int __stdcall Initialize( unsigned char *imagebuffer,struct config *Configuration);
The passed struct is similar to
struct config
double                val1[3];
unsigned short   val2;
bool                    val3;
bool                    val4[3];
unsigned char    val5;
unsigned char   val6[3];
bool                    val7[26];
For passing "unsigned char *imagebuffer" I initialized array with "Numeric constant " and set the size of the array and send to the function.
The problem here is, I used this array in one of the subvi.
How can I use the returned imagebuffer array in my main demo program. How to connect the image array to subvi "Connecter Pane"
And which control can I use to display the image. The image data I get is form of 1-D Array .
The second problem is,
   For passing the structure, I used "Bundle " and filled the bundle with all the datatypes as in my struct and passed to the function. Is it correct ? How to access this bundle after returned from function in another Vi. ie.) How to connect this bundle to the connter pane ?
Thanks for your valuable suggestions.

You say nothing about how your cluster looks but I'm afraid you did the standard error here and placed arrays in it. That is not what the C structure is representing for several reasons.
First fixed size arrays in C are inlined inside a structure, so are not a pointer but for the case of your val1 element three doubles.
Second although not relevant here because of above point: LabVIEW arrays are not the same as C arrays. LabVIEW uses a pointer to a pointer and has the size of the array in elements prepended to the array data. C simply uses a pointer and all the rest is the programmers sorrow. The Call Library Node does convert the top level element of variables you pass according to the type configuration of that parameter but does no conversion of internal elements at all. So passing clusters with anything like arrays or strings is always wrong unless the DLL is aware of the specific datatypes LabVIEW uses.
Last but not least you can end up with alignment issues. Elements in structures are aligned by every C compiler to a certain value. This value can be defined by the programmer in the project settings or for Visual C through #pragma pack() statements in the C code. The alignment rule says that an variable is aligned to the smaller of the two values that are either a multiple of the variable element size or the alignment setting. Most 32bit code nowadays uses 8 bit default alignment but LabVIEW always uses 1 byte. In your case there is nothing to observe since the large variables are at the beginning. Otherwise you might have had to insert filler elements in the LabVIEW cluster.
One last thing bool is a C++ type only. Its size is 1 byte and incidentially this is the same LabVIEW uses for Booleans.

Running SQL Server Function and Procedures from Oracle

I am trying to run SQL Server 2005 functions and/or procedures from a SQL statement in Oracle. I have gone throught the hetergeneous services and have connected to the SQL Server database successfully. I can also do a query to a table in SQL Server successfully; but I have not been able to execute a procedure or a function.

Have you tried Oracle syntax? It seems to me that you have only tried T-SQL syntax, e.g. execute proc.
Wrap it in a begin..end tag like you would a normal PL/SQL function or proc call. Assumption is that as Oracle makes the remote database (via the dblink) look like an Oracle database, you should also play along and pretend it is one and treat it as such.
E.g.declare
r integer;
begin
-- execute remote proc
procFoo@dblink( 'ABC' );
-- call a remote function
r := funcFoo@dblink( 123 );
end;
