Well, as i said, it could be that your VARIANT contains something else than a string, like an integer for example, check this[^] out and you will see there can be a lot of datatypes a VARIANT can hold. So -based on what you see there- you should either skip non-string values or maybe convert what you can to a string if you really need to work with a string.

Use VariantChangeType[^] to convert the VARIANT to one holding a BSTR representation of the data before trying to use the BSTR.

Hi,
i write this simple program and execcte it. i thought that it will give all the name of directories where it was placed , but it is not working as i was thinking.i don't want to use system() function in place of crateprocess().my code is following-
#include<windows.h>
#include<stdio.h>
int main()
{
char *command="dir";
STARTUPINFO si = {sizeof(STARTUPINFO)};
PROCESS_INFORMATION pi;
CreateProcess("C:\\Windows\\System32\\cmd.exe", command, NULL, NULL, 0, 0, NULL, NULL, &si, &pi);
return 0;
}
please help me.i want to give command to createprocess() only when program is written not after execution of program.

I don't really understand what you're trying to do, especially this is confusing:

Anyway, it seems that you want to start a new command shell and pass a parameter. In order to do that you would need this:
cmd /C dir
To do that with CreateProcess() I suggest the following code:
STARTUPINFO si;
PROCESS_INFORMATION pi;
::ZeroMemory(&si, sizeof(STARTUPINFO));
::ZeroMemory(&pi, sizeof(PROCESS_INFORMATION));
si.cb = sizeof(STARTUPINFO);
if (::CreateProcess(NULL, "cmd.exe /C dir", NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi) == 0)
return FALSE;

thanks Michael Schubert, same thing i want to know with you.actually when i use
CreateProcess(NULL, "cmd.exe ", command, NULL, FALSE, 0, NULL, NULL, &si, &pi)
it will open a command prompt and then i have to write dir but i don't want that.
anyway it works fine but i didn't understant why you put /C dir .can you please explain it?

See the Windows Help for cmd. A statement such as cmd /C dir tells cmd to run the command 'dir' and then terminate. Without the /C option it will start a new cmd shell.

Did you try typing cmd dir in the Run dialog box and see what that did?
That aside, why are you not using the FindFirstFile() and FindNextFile() pair like was suggested here?

I am using Visual Studio 6.0 when I tried to use add new files to my existing project it crashes (does the error report thing).
I also tried uninstall and reinstall visual studio..., but it does the same thing...
I have also gotten an error- MSDEV.EXE - application error...
"The instruction at "0x519e1a5b" referenced memory at "0x02004f48". The memory could not be "read""
I think this is the first time, so I have no idea if it ever worked...
I am using Win XP PROFESSIONAL SP-2.
Thanx in advanced,
Ratheesh.

hello Ratheesh
This may sound strange, but even I had a similar issue with VC6 after installing Project / Visio 2003 / 2007. Have you installed any of these softwares recently, or you have this problem since the beginning?
Thanx

Hi Vipin,
Yes that was the problem, thank you very much for your help.

How about the Process32First() and Process32Next() pair? They populate the PROCESSENTRY32 structure.

I trongly suspect that default icon code of MFC dialog based app is almost totally useless.
Only useful code are the 2 lines:
m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
SetIcon(m_hIcon, FALSE);
After deleting message handle OnQueryDragIcon(), SetIcon(m_hIcon,TRUE); and code in OnPaint(), visual icon on dialog interface and file-manager keeps the same.
Do you think default code I deleted is usefull in some cases?
