First Tell me Which wrapper class are you using, secondly you can pass the name of doc file itself instead of passing the folder name while creating zip file!

Use LoadLibrary function
and use GetProcAddress function to get the address of the methods

The GetProcAddress API sucess only if the Dll exports the function as follows

__cdecl __declspec(dllexport) returntype function name (parameters,...);

because C++ Mangles the function names due to that GetProcAddress fails,to avoid that use C style definition of the function

Knock out 'T' from CAN'T ,
You 'CAN' if you think you 'CAN'

HMODULE hModule = LoadLibrary("path of dll");

Get the function pointer(typedef return type
ex:- typedef int (*funptr) ("arguments");
funptr f1 = GetProcAddress(hModule,"function name");

f1("arguments");

1.Include the exported .h file(this file should contain the method declarations that u want to use) of the Dll file into your current application.

2.Copy and paste the .dll and .lib file into u r application \debug or \release folder.

3.Go to Tools->options->Directories and include the .lib and .h file paths.

Now u can call the methods of the dll as normal methods.

Appu..

you have manually add that in your application
i.e.
OnMessage(WM_DISPLAYCHANGE,OnDisplayChange)

Function Decalaration
LRESULT YOURCLASS:OnDisplayChange(WPARAM wParam,LPARAM lParam)

Hi,

I have a timer which was working proeprly before adding threads, now i have added thread funtion after that timer is not displayed on the dialog window can anyone tell me what is the cause .....

-------------------------------------------
BOOL CStatusDlg::OnInitDialog()

CDialog::OnInitDialog();
HANDLE hr;
hr = CreateThread(NULL,0,(unsigned long (__stdcall *)(void *))WorkerThreadProc,this,0,0);
return TRUE;
}

---------------------------------------------------

UINT WorkerThreadProc(LPVOID Param)
{
CStatusDlg* status = (CStatusDlg *)Param;

time(&lStartTime);
SetTimer(NULL,ELAPSED_TIMER, 1000, NULL);
INDX.startIndex();
return true;
}
------------------------------------------------------

void CStatusDlg::OnTimer(UINT nIDEvent)
{
// TODO: Add your message handler code here and/or call default
if(nIDEvent == ELAPSED_TIMER)
{
time(&lStopTime);
cteElapsedTime = CTimeSpan(lStopTime-lStartTime);
CString csElapsedTime;
csElapsedTime.Format("%02d:%02d:%02d",
cteElapsedTime.GetHours(),
cteElapsedTime.GetMinutes(),
cteElapsedTime.GetSeconds());

I think the thread does not know to which dialog the timer belongs. D'Oh! | :doh:

try change:
SetTimer(NULL,ELAPSED_TIMER, 1000, NULL);
to:

status->SetTimer(NULL,ELAPSED_TIMER, 1000, NULL);
