Why don't you fire up the debugger and find out for yourself?
(VS6): "Debug build", Set a breakpoint (F9), and press F5

You would have saved 1 hour, 40 minutes...

Including single-stepping your program in the debugger? While inspecting the values of the interesting variables? And watch the flow of the program?

Processes creatation and termination notifications monitoring

Hey,

I am trying to write a program that will run on about 40 computers at my work to monitor the processes. The way I would like to do it is run a small program in the background that receives notifications events from the kernel every time a process is created or terminated and then reports the information to a server computer. I am able to handle the communication with the server fine, but the receive notification events is causing me a bit of trouble. I have been trying to use http://www.codeproject.com/threads/procmon.asp <-- this example to do just that but it does not always report the process name, sometimes only the process id. If anyone is able to give me an example that works or point me in the write direction would be great.

Thanks in advance Smile | :)

It is very difficult to guess the problem, without seeing code.
But, somewhere in your code, memory is handled/used in wrong way. Possibly, written out of boundry. So, check, how you have handled it.

This is an excellent time to use your debugger. Follow the call stack until it reaches code that you have written. There you will find the cause of the error.

Can you post some code snippet for other's to see and check? It's very hard to tell with the information that you provide now. As said above it is possible that you may be writing to an invalid memory location causing the application to crash.

Somethings seem HARD to do, until we know how to do them.

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.

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 ?

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.
