You need to use CreateProcess instead.

It will give you a process handle in one of the structures you pass it.

If CreateProcess returns successfully, WaitForSingleObject the process handle (assuming you are not in a GUI thread) and then call the magic api function GetExitCodeProcess. Oh - and don't forget to CloseHandle on the returned process and thread handles.

I hope you have used this code.

WinExec("regsvr32   c:\\MyDll.dll",0);

If yes, It works perfectly(It show messagebox of succes or failure).

Dear Parsad, you are 100% right, but the problem is that I want to run that command in silent mode, with out prompting a message box.

then you need to pass this string.
"regsvr32 /s mydll.dll"

Not necessarily, WinExec("regsvr32 mydll.dll" , SW_HIDE), this can also work for silence.

NO , it wont(Try it with above code). Second parameter is for window based applications.
You need to mention /s.

As mentioned in MSDN, use CreateProcess, with command line options given.

Would it not be easier to register the dll yourself (see below).

HINSTANCE hDll;
HRESULT  hReply;
HRESULT (FAR *lpDll) (void);

hDll = LoadLibrary(szFile);

if (hDll > (HINSTANCE)32)
{
    if (bRegistering)
    {
        lpDll = (HRESULT (FAR *) (void)) GetProcAddress(hDll, "DllRegisterServer");
    }
    else
    {
        lpDll = (HRESULT (FAR *) (void)) GetProcAddress(hDll, "DllUnregisterServer");
    }
        hReply = (*lpDll)();

        if (hReply != 0)
        {
            // Display register/unregister error message here
        }
    }

    FreeLibrary(hDll);
}
else
{
    // Display Dll load error here
}

Why one would like to use CString in WIN32 application? Use std::string instead.

Define this, and you will have CString in Win32

#define _AFXDLL<br />
#include <afx.h><br />
#include <afxwin.h>

Make that

#define _AFXDLL<br />
#include <afx.h><br />
#include <afxwin.h><br />

Hmm, i'm sure i wrote afx.h and afxwin.h! i guess the angled brackets is the culprit!! :P

Yep... View Source did the trick.

I was just browsing the forum and figured I might as well make it easier for the OP.

I guess that's just one drawback of allowing html in posts. Smile | :)

Again, why one need to use MFC classes in WIN32 app, if standard library function do ?

hooking process termination

PK218430-Nov-06 19:58

30-Nov-06 19:58

Problem:

We have a server. Have used VC++ 6.0 compiler. Have used try-catch including catch(...) at several places.

Problem is when there is some problems like SEGV ie memory access violation, control goes to catch(...). Unlike unix there are no signal handlers here for this.

Can we somehow hook the process termination so that before server crashes we can print the stack trace using one written by us?
Problem here is how to hook the process termination??

Compiler used is VC++ 6.0
OS: windows 2000

I haven't used it in ages since I normally use the C++ try/catch blocks. However, you might read up on Structured Exception Handling, which is a bit of a different thing, and see if it provides the functionality you need.

Hope this points you in the right direction.

bool MyFunc
{
 return (Func1() && Func2());
}

where return type of Func1 and Func2 is bool. What i want to know in which order do they called in the above statement. whether Func1() called first or the Func2()? As I want Func1() should be called first. Is it the way i should write?
Thank you.
