Hello friends,

For one of my projects I need to call jar files from the visual c++ application. Can anyone tell me how this can be done. If sample code is there then it will help a lot or the API if there is any.

Thanks for your reply.

I believe you need to look into JNI: http://www.codeproject.com/java/jnibasics1.asp[^]

If you just want to unpack the jar file then use ShellExecute.

Prepare a command string like "Cmd.exe YourJarFilePath.jar -Arg1 - Arg2", then pass it to ShellExecute.

This might be a bit helpful. Can you send me a sample code say I want to call a jar file at location C:\psae.jar with the parameter "world" then the syntax from command prompt is :
java -jar C:\psae.jar world

How the command string should look like for this one ?

Thanks for your reply

So in this case the command will be the same...

Look up ShellExecute in MSDN.

The lpFile parameter should be "java.exe" and lpParameters should be "-jar C:\psae.jar world".

It didn't work. When I use debuger, it shows me the return value of the shellexecute as 2 and the value for getlasterror is the same. I dont knokw how to deal this ?

I am using the following code snippet :

HINSTANCE hInst;<br />
hInst= ShellExecute(NULL,reinterpret_cast<LPCWSTR>("open"),reinterpret_cast<LPCWSTR>("C:\j2sdk1.4.2_12\bin\java.exe"),reinterpret_cast<LPCWSTR>("-jar C:\psae.jar WORLD"),NULL,SW_SHOWMAXIMIZED);<br />

and even try with this one :

hInst= ShellExecute(NULL,reinterpret_cast<LPCWSTR>("java"),reinterpret_cast<LPCWSTR>("C:\j2sdk1.4.2_12\bin\java.exe"),reinterpret_cast<LPCWSTR>("-jar C:\psae.jar WORLD"),NULL,SW_SHOWMAXIMIZED);<br />

both shows the same error.
Error no. 2.

Why all of the reinterpret_cast() code? Aren't you forgetting to use double backslashes in your string literals?

What's not to understand?

HINSTANCE hInst = ShellExecute(NULL, "open", "C:\\j2sdk1.4.2_12\\bin\\java.exe", "-jar C:\\psae.jar WORLD", NULL, SW_SHOWMAXIMIZED);

If you are using Unicode, just precede the string literals with an L.

See here and here. Using these examples, you should be able to get the output of java.exe.

Hi, just wrote a message but I don't get a solution to my problem so I retry:
I need to manage an ActiveX component created on the mainWnd of my App, into a thread.
In particular I need to fill a grid (as I just said, created in the MainWnd) from a thread (on the Run() function), so while the app go on.

I pass to the thread the grid's pointer but at run time an Error messageBox appears that say "Invalid pointer value".

How can I solve it?

Thanks.

FW_BOLD in place of FW_NORMAL will do. Why would you suggest FW_NORMAL for some who wants to render bold text? Roll eyes | :rolleyes:
