How cot create and read files in ALLUSERSPROFILE directory

Hi,
I have a program that is to be used both with Windows XP, Vista, 7 and 8. It should create and read a file in ALLUSERSPROFILE, which I have learned to be different directories in XP and the other Windows versions. But after looking all over internet, I can't
find any clear answer how to do this. I thought the following should work, but it doesn't:
testfile = fopen("%ALLUSERSPROFILE%/testfile.dat", "r");
Although the file exist, testfile gets the value of zero. I've also tried other strings instead of "ALLUSERSPROFILE," but no luck. Could anyone tell me how to do this?
Thanks in advance.

I tried the following:
     SHGetKnownFolderPath( &FOLDERID_ProgramData, 0, 0, &userpath);
Then the program compiled. But it did not work:
     fopen("%userpath%\\Testfolder\\Testfile.ini", "r");
did not open the file, although it is there.
Then I read that this function can't be used with Windows XP, so I
switched to the deprecated SHGetFolderPath
    TCHAR userpath[MAX_PATH];
     SHGetFolderPath(0, CSIDL_COMMON_APPDATA, 0, SHGFP_TYPE_CURRENT, userpath);
According to the MSDN pages, one then could use the
    PathAppend (userpath, TEXT("Testfolder/Testfile.ini"));
I then added Shlwapi.h and compiled and got the following error message
     main.obj : error LNK2001: unresolved external symbol __imp__PathAppendW@8
     fatal error LNK1120: 1 unresolved externals
Then I again tried
   fopen("%userpath%\\Testfolder\\Testfile.ini", "r");
but neither did this work. So now I don’t know what to do.

How to keep and read files on the client side?

There's a web page with a certain X3D model, and there are several inputs on the same page. When a user submits the form, the servlet changes the model and returns a page based on the input values. The problem is that the part of this model is a human body (which is pretty tough for downloading). What I'm trying to find out is if there's some way to store that model on the local computer and then access it from the servlet without regetting it from the server. Thanks.

With JSP you can't run java code on the client. All of it runs on the server.
To run java on the client, you use an Applet.
Alternatively you go the pure html/javascript way, and write javascript includes for code.
Or you use something like AJAX, to submit the form, and receive back only "changes" to the model.
Not sure if that helps at all.
Good luck,

Ah, it looks like I should have read your title more carefully. Are the files on the PCs that you want to share with your iMac in a shared folder?
If not, follow the steps on this page to set up shares from Windows 7.
If that is already set up, connect to the share from the iMac using this article.

How to create and read text file using LabVIEW 7.1 PDA module?

How to create and read text file using LabVIEW 7.1 PDA module? I can not create a text file and read it.
I attach my code here.
Attachments:
File_IO.vi ‏82 KB

Well my acquisition code runs perfect. The problem is reading it. I can't seem to read my data no matter what I do. My data gets saved as a string using the array to string vi but I've read that the string to array vi (which I need to convert back to array to read my data) does not work on the pda. I'm using version 8.0. So I was trying to modify the program posted in this discussion so that it would save data from my DAQ. I did that but I still can't read the data after its saved. I really don't know what else to do. All I need to do is read the data on the pda itself. I can't understand why I'm having such a hard time doing that. I found a possible solution on another discussion that talks about parsing the strings because of the bug in the "string to array" vi. However, that lead me to another problem because for some reason, the array indicators or graphs don't function on the pda. When i build the program to the pda or emulator, the array indicators are faded out on the front panel as if the function is not valid. Does this kind of help give a better picture of what I'm trying to do. Simply read data back. Thanks.

How to get and read a file from META-INF directory

How to combine both DAQ AI signal, write and read file in single VI

Hi
I am the new user of LabVIEW version 7.1 for testing automation application. I have to measure 33 signals ( mostly analog like temp, pressure, etc...) from NI USB 6210 DAQ system and write in master file for future verfication.From real data or from master file back up have to write one more file if only the signal reaches steady state , which will used for analysis and same signals to be read from this file parallely & make a waveform and/or table display format.
Pl. help me to shortout this problem
note: I have plan to ugrade labVIEW version 2011 shortly, so let me know doing parrel acquistion write and read file for data analysis in same VI in version 7.1......

Parallel operations in LabVIEW are very simple. Just code it in parallel and it will work.
Try taking a look at some of the examples in the NI Example Finder (Help > Find Examples). There you will find example for writing to and reading from files, as well as data acquistion in parallel with other operations.
You might need a producer/consumer architecture is you are acquiring data very quickly.

How to access the *.java file corresponding to a TypeElement T?

Here is a problem:
How to access the *.java file corresponding to a TypeElement T from a AnnotationProcessor environment?
Let us say the hook method
public boolean process(Set<? extends TypeElement> annos, RoundEnvironment roundEnv)
is invoked with a TypeElement T such that T.getQualifiedname() = "a.b.c.X"
And the problem is how to locate the file that has the *.java source code for a.b.c.X?
That is the file that has the source code for a.b.c.X say "some/path/a/b/c/X.java"?
For simplicity, let us assume that TypeElement T corresponds to a top-level Java class.

Pinaki wrote:
That is not something you as the annotation processor author should be asking about. That is something you the person configuring the javac environment should set up via the -d option or its equivalent.
I strongly recommend using a separate output directory hierarchy.That is the way the current implementation is. The annotation processor takes a -Aout= <some directory path> to write generated output relative to a user-specified location (which defaults to the class output location).That is contrary to the design of the annotation processing facility. The intended use is for that information to be configured via options like "javac -d".
Additionally, IMO it is a serious configuration error to put generated files and input files, presumably tracked under version control, in the same directory. Interesting you said that. We are just running some "field trial" with these things and some users want them to be in the same directory of the original *.java files (especially when their source files are spread across many roots) .
Who knows what the user wants?The user does and the user is free to (mis)configure their environment however they like ;-) However, that is the user's option and the user has control of this via the javac command line. The annotation processor is not the proper place to configure this setting; see slide 7 of http://blogs.sun.com/darcy/resource/J1_2006-BOF-0606.pdf for some thoughts on different roles in annotation processing.
presumably tracked under version control, in the same directory.version control is another 'usability issues' that we are trying to get our heads around with this stuff. "To check-in or not?" - that seems to be the question. When presented these facilities without any cue, "the users" were divided -- some wanted them to be checked-in, some did not. The context where these generated files being used -- there exists some rationale to check them in a version control system.The right answer depends on the circumstances, but IMO generally generated files should not be checked in under version control, especially if they are derived from other source files. Checking in generated files of this nature just creates the opportunity for them to get out of date with the originating files.

How to access and display a Web Service from a WSDL in JSP or JSTL ?

Dear All,
We need to access a Web Service which is hosted as WSDL How to access a WSDL file from JSP or JSTL, parse and display the SOAP response in JSP page.
Any simple example or URL as reference to an example will be useful for me.
It seems io tags of jakarta is able to send soap message, but how to display it in JSP.
Yours,
Sankar.B

Dear Sir,
Yes. I would like to know more about the Forte and how to consume WSDL file from JSTL. The following are my querirs.
1. How to connect the declared JNDI from a JSP page. i.e: the Datasource - ex: booksDS
2. We connect the Tomcat server using JNDI as jdbc/scott. But, if I give jdbc/scott in JSTL as datasource={jdbc/scott}, we could not able to connect. We use the following code in a JSP page to connect the DB from a JSP page. (Its quite easy to modify, so we use the connection in a JSP page.)
3. How to Consume a WSDL url from JSTL. Ex: If there is a URL : http://localhost/ws/MathService.asmx?wsdl OR http://www.xmethods.com/test/BabelFish
4. How to display the result. We tried via SOAP from io taglib of Jakarta, but gives us an SOAP (it also looks like xml) response. But, how to use the value from that soap response in IE client thru JSTL/JSP.
5. Whether this JSTL tool will be available with Forte Enterprise/Community Edition. If so EE, whats the price.
Please Reply Immediatly. We tried, trying, going to try to display a wsdl response, but not able to display in IE thru JSP/JSTL. But, weve tested the www.gotdotnet.com examples of asp.net web services, we are thru. Its quite easy it seems in .NET. But, we feel whether even there is not even one example in JSTL/ Java Web Services Dev. Pack to utilise a web service in full cycle. The example which uve given is thru servlets. We dont use servlets. Cos, its very easy to edit JSP pages, instead of compiling the serv. and using it.
I hope ull reply for all the above queries, since ur from SUN.
Expecting your fav. reply.
Yours,

How to open Adobe Reader file from another native IOS application?

There is an existing thread, but I want to re-open it because I think this is an important feature that we need badly. I was wondering if there is any plan to add this feature so we can open PDFs directly into Adobe from the web / other apps.
How to open Adobe Reader file from another native IOS application?
Basically, we just want to use a custom URL scheme to open a specific document in the App. Currently, this only opens the app but does not load the file.
APB

Not to hijack the conversation but I can explain why this would be useful for both the above case and another.
What I believe Pavel is talking about is setting up a "URL Scheme" for the Adobe Acrobat iOS application so that you can easily open a PDF specifically in Adobe Acrobat iOS from other native applications and even from web applications opened within Safari. This is particularly useful if your application requires some of the specific features in Adobe Reader iOS to grant them the best experience possible and you want to encourage this.
Another case: If you're using Adobe Livecycle's document security modules (that encrypts PDF files so that Adobe Acrobat must "phone home" to decrypt and view the document), these PDF's can only be viewed inside the Adobe Acrobat application and appear as blank in most other PDF readers. Having a URL scheme allows your application utilising this functionality to have a 1 click step to view the PDF rather than the current non-user friendly process:
- Within Safari, touch the PDF link (appears as blank in the default Safari PDF reader, which in itself is confusing)
- Touch "Open in..."
- Touch "Adobe Acrobat"
We have an immediate need for this functionality for the example above. I can resubmit it in a separate post if necessary.

How to access/open rpd files in offline mode from client desktop

Hi All,
Please tell me what configuration settings I need to have on my desktop to access RPD files stored on BI server?
In our OBIEE environment, we have BI server installed on linux server, and I have installed BI admin tool on my desktop (Windows OS).
I need to know what settings I should configure in my NQSConfig.ini file on my desktop so that I can access rpd files stored on BI server...
I can access online RPD using BI server ODBC connectibity, but want to access other offline RPD files stored in repository directory on linux server where OBIEE 11g server installation is done.
Thanks and Regards
Santosh

Saichand,
Highly appreciate your response.
But wht I am looking for is how to access other RPD files stored in repository folder on server machine where BI server is running, from BI administration tool which is installed on my desktop
I am able to access default online repository on BI server using ODBC configuration from BI admin tool on my desktop, but want to access other rpd files (lets say sample rpd files which are installed on BI server machine) using (file->open-offline) option.
As per Jay, it seems it is not possible to access repositories other than online repository on BI server, and I will have to copy those rpd files on my desktop and then access using file->open->offline option in BI admin tool.
If you have any other way of doing this or have done this somehow , please let me know.
Thanks and Regards
Santosh

Excellent question. I don't see any client-jar in your EAR file structure. So I am assuming you are writing a separate client application which will talk to the ejbs deployed as part of this EAR. You need to do the following:
Write another EAR file with the following structure:
ear:
META-INF/application.xml
util.jar
client.jar
client.jar should have a META-INF/MANIFEST.MF and that should contain Class-Path:util.jar and value for Main-Class attribute.
Now deploy this new ear to your application server and execute it using Application Client Container that comes with your app server.
If you don't want to write another EAR file, then bundle th client.jar in your original EAR file.
Points to note are:
you have to repackage util.jar again inside this ear file.
For portability reason, you should use Class-Path manifest entry in client.jar. Refer to http://java.sun.com/j2ee/verified/packaging.html and J2EE platform spec section #8.2.
Hope this helps,
Sahoo
