HCRET lpfnDllRegisterServer = NULL;
DLLName = "YouDLLName.dll";
hDLL = LoadLibrary(DLLName);
if (hDLL != NULL)
{
lpfnDllRegisterServer = (HCRET)GetProcAddress(hDLL, "DllRegisterServer");
if(NULL == lpfnDllRegisterServer)
{
//ERR
}
else

if(FAILED((*lpfnDllRegisterServer)()))
{
ERR ("Tripio registration failed!");

HRECT is just a function pointer type def as

typedef HRESULT (CALLBACK *HCRET)(void);

Let me know worked or not to anilkumarkv@gmail.com

As we can Register a dll using 'regsvr32.exe', is there any option to unregister the register dll?

you can dynamically load dll and call teh dllunregister routine

Let fatCom.dll is your DLL ....
then using LoadLibrary function load that dll in your Process memory space and using GetProcAddess Function get DllUnregister pointer and call that function!

I use code as follow,

HCRET lpfnDllRegisterServer = NULL;
	HINSTANCE  hDLL = LoadLibrary("SimpleExt.dll");
	if (hDLL != NULL)
	{
		lpfnDllRegisterServer = (HCRET)GetProcAddress(hDLL, "DllUnregister ");

		if(NULL == lpfnDllRegisterServer)
			MessageBox("ERR");
		else
		{
			if(FAILED((*lpfnDllRegisterServer)()))
				MessageBox("Dll registration failed!");
			else
				MessageBox("Registering DLL Success");
		}
		
		FreeLibrary ( hDLL );
	}
	else
		MessageBox("LoadLibrary failed");

But it is showing MessageBox("ERR"). (in BOLD)
What is the problem?

pass DllUnregisterServer instead of DllUnregister

how to make a commandLine to wait

19-Jul-06 20:26

The dll I am tring to Unregister/Register in written by myself using 'ATL COM Appwizard' in VC6. But when I use other dll to register/unregister using following code, it is working. Then what might be the problem?
When I register/unregister other dll (not mine). using following code (code given by u). It is working fine. But same code for my dll is not working, that dll I can register/unregister using "regsvr32" command in command prompt. Then what might be the problem ?

typedef HRESULT (CALLBACK *HCRET)(void);

HCRET lpfnDllRegisterServer = NULL;
HINSTANCE hDLL = LoadLibrary("SimpleExt.dll");
if (hDLL != NULL)
{
lpfnDllRegisterServer = (HCRET)GetProcAddress(hDLL, "DllRegisterServer");
//lpfnDllRegisterServer = (HCRET)GetProcAddress(hDLL, "DllUnregisterServer");

if(NULL == lpfnDllRegisterServer)
MessageBox("ERR");
else
{
if(FAILED((*lpfnDllRegisterServer)()))
MessageBox("Dll registration failed!");
else
MessageBox("Success");
}
FreeLibrary ( hDLL );
}
else
MessageBox("LoadLibrary failed");

How to use this. I have declared it as,

typedef HRESULT (CALLBACK *HCRET)(void);
HCRET lpfnDllRegisterServer = NULL;

Are you spawning another exe? There are multiple version of the spawn and exec commands that include a variation that waits for the spawned exe to finish. Is that what your looking for or are you asking to keep the command window from a command line window open after some processing to view results?

If the latter, then put something like a getchar() in there to make it wait for a keypress...

int main(int argc, char* argv[])
{
// Processing here?

printf("Press a key to continue\n");
getchar();
return 0;
}
