Using the application's obects data member "m_pszHelpFilePath"
i can get the target path.(where the exe is really stored).
Now i need the path where the short cut of the exe is stored. Mad | :mad:

u should use GetModuleFileName() to retrive the path o exe instead of the above trick.

u can get the path of short cut( if the process is started using a short cut ) using the GetStartupInfo() function. This method is explain in the link that i supplied in previous post under the section Detect if an executable was started from a Short-Cut. Did u check that?

Use GetModuleFileName() to get the path to the EXE. As for the path to the shortcut that launched the EXE, AFAIK that info isn't available to the process. Explorer reads the shortcut and calls CreateProcess(), but once the process is running, the shortcut is no longer relevant.

Check out GetFileVersionInfoSize(), GetFileVersionInfo(), VerQueryValue().

Here's one way to read the VERSIONINFO resource of a file (if it exists)

LPCTSTR pszFileName = _T("C:\\TEST.DLL");
DWORD FVHandle;
 
DWORD dwSize = ::GetFileVersionInfoSize(pszFileName, &FVHandle);
if (dwSize)
{
   void *pVersionData = (LPVOID)new BYTE[dwSize];
 
   if (::GetFileVersionInfo(pszFileName, FVHandle, dwSize, pVersionData))
   {
      TCHAR szSubBlockName[256];
      UINT nSize;
 
      // Get fixed file version info
      const VS_FIXEDFILEINFO *pFixedFileInfo;
      _tcscpy(szSubBlockName,_T("\\"));
      if (::VerQueryValue(pVersionData, szSubBlockName, (void **)&pFixedFileInfo, &nSize))
      {
         // version info in VS_FIXEDFILEINFO struct pointed to by pFixedFileInfo
      }
   }
 
   delete[] (BYTE *)pVersionData;
}

Strings like company name, program name, copyright, etc. in a VERSIONINFO resource can exist in
several languages so it's slightly trickier retrieving those.

I am using SHBrowseForFolderA for showing a file dialog. The length of the selected path is geyting trimmed.

I've used these flags
bi.ulFlags = BIF_RETURNONLYFSDIRS | BIF_STATUSTEXT;

Is there any way by which i can increase the size of the label in the dilaog box for the currently selected path.

Thanks,

Working with win 32 timers.

Hello All,

I have a working timer in MFC can anyone tell me how to change it to Win 32.

MFC Timer Code.<br />
<br />
// Declarations<br />
#define ELAPSED_TIMER 101<br />
time_t lStopTime;<br />
time_t lStartTime;<br />
CTimeSpan cteElapsedTime;

<br />
//Start Timer<br />
time(&lStartTime);<br />
SetTimer(s->m_hWnd,ELAPSED_TIMER, 1000, NULL);<br />

<br />
//Kill Timer<br />
KillTimer(s->m_hWnd, ELAPSED_TIMER);

<br />
//Timer Function<br />
void CSDlg::OnTimer(UINT nIDEvent) <br />
{<br />
	if(nIDEvent == ELAPSED_TIMER)<br />
	{<br />
		time(&lStopTime);<br />
		cteElapsedTime = CTimeSpan(lStopTime-lStartTime); <br />
		CString csElapsedTime;<br />
		csElapsedTime.Format("%02d:%02d:%02d", <br />
		cteElapsedTime.GetHours(),<br />
		cteElapsedTime.GetMinutes(),<br />
		cteElapsedTime.GetSeconds());<br />
		if(IsWindowVisible())<br />
		{<br />
			m_TIME.SetWindowText(csElapsedTime);<br />
		}<br />
	}	<br />
		CDialog::OnTimer(nIDEvent);<br />
}

How to change it to win 32 application ?? what are the changes which I have to make in the below code????

<br />
<br />
int APIENTRY WinMain(HINSTANCE hInstance,<br />
                     HINSTANCE hPrevInstance,<br />
                     LPSTR     lpCmdLine,<br />
                     int       nCmdShow)<br />
{<br />
 	// TODO: Place code here.<br />
	INT_PTR mRet = DialogBox(hInstance, <br />
                            MAKEINTRESOURCE(IDD_MAIN),<br />
                            GetDesktopWindow(),<br />
                            MainDlgProc);<br />
	return 0;<br />
} <br />
<br />
<br />
BOOL CALLBACK MainDlgProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)<br />
{<br />
	<br />
	switch(Message)<br />
	{<br />
<br />
		case WM_INITDIALOG:<br />
		{<br />
			SetTimer(hwnd,IDT_TIMER, 1000,(TIMERPROC) NULL);   <br />
		}<br />
			break;<br />
		<br />
		<br />
		case WM_CLOSE:<br />
			EndDialog(hwnd, 0);<br />
		break;<br />
<br />
		case WM_COMMAND:<br />
<br />
			switch(LOWORD(wParam))<br />
			{<br />
			    case IDC_EXIT:<br />
				     EndDialog(hwnd, 0);<br />
			   	     break;     <br />
					 <br />
				case IDC_Start:<br />
				//Starts the timer on button click<br />
<br />
					break;<br />
				<br />
                                 case IDC_End:<br />
                                 //Ends the timer on button click<br />
				  KillTimer(hwnd, IDT_TIMER);<br />
      				  break;<br />
			}<br />
			default:<br />
			return FALSE;<br />
	}<br />
	return TRUE;<br />
}

You need to add one more case here,

case WM_TIMER:
if((UINT)wParam== ELAPSED_TIMER)
{
//do your stuff
}

Hi Prasad,

Thanks for the response.

In the declaration only I am getting error. But it is working in MFC.

Hw to do it in Win32 ???

#define ELAPSED_TIMER 101<br />
time_t lStopTime;<br />
time_t lStartTime;<br />
CTimeSpan cteElapsedTime;

error C2146: syntax error : missing ';' before identifier 'cteElapsedTime'

Use difftime instead. See its MSDN example.

Prasad example gives the time diffrence only.

int main( void )<br />
{<br />
   time_t   start, finish;<br />
   long loop;<br />
   double   result, elapsed_time;<br />
<br />
   printf( "Multiplying 2 floating point numbers 500 million times...\n" );<br />
   <br />
   time( &start );<br />
   for( loop = 0; loop < 500000000; loop++ )<br />
      result = 3.63 * 5.27; <br />
   time( &finish );<br />
<br />
   elapsed_time = difftime( finish, start );<br />
   printf( "\nProgram takes %6.0f seconds.\n", elapsed_time );<br />
}
