Hi Mauricio,
Not positive on the DLL side. I have done the following in a stand alone
EXE.
void WINAPI LaunchAndWait(LPSTR lpszFilename)
{
PROCESS_INFORMATION ProcessInformation; // Holds information on launched
process
STARTUPINFO StartupInformation; // Holds information on startup of
process
DWORD dwReturn; // Holds information on wait
BOOL boolReturn; // Indicates successful operation, maybe
!
// Initialise startup information structure.
StartupInformation.cb = sizeof(STARTUPINFO); // Set size of
structure
StartupInformation.lpReserved = NULL; // Must be NULL
StartupInformation.lpReserved2 = NULL; // Must be NULL
StartupInformation.cbReserved2 = 0; // Must be 0
StartupInformation.lpDesktop = NULL; // Inherite process desktop
StartupInformation.lpTitle = NULL; // No title
StartupInformation.dwFlags = 0L; // No setup flags
// Create a process for the main installation programme.
boolReturn = CreateProcess(lpszFilename, NULL, NULL, NULL, TRUE,
NORMAL_PRIORITY_CLASS, NULL, NULL,
&StartupInformation, &ProcessInformation);
// Check the process successfully created.
if (boolReturn != FALSE)
{
// If process launched and running wait for same to close and then
// shutdown the process space.
dwReturn = WaitForSingleObject(ProcessInformation.hProcess, INFINITE);
boolReturn = CloseHandle(ProcessInformation.hProcess);
}
else
{
MessageBox(NULL, M_INSTALL_FAILED, M_APPLICATION_NAME, MB_OK);
}
return;
}
As the name of the routine implies it launches another application and wiats
for the applications process to finish before continuing to execute. Your
man might like to give it a whirl and see if this helps.
Neil.
