Opening other application from our own application

[Katamneni]

Dear All I want to write a dialog based application where user is prompted to choose some file using CFileDialog. I have to open the file selected by the user with default Shell editor associated with that file from my application ( For e.g, if user selecets "Sample.bmp", i must be able to run "mspaint.exe" application with "sample.bmp" opened for editing from my application ) and i must not allow user not to do any operation with my application till he closes the opened application. Can somebody help me in implementing this functionality. Thanks in advance Regards Krishna

Hi, you can use ShellExecuteEx() and the use the handle to the created process returned by it to check its existence. Bye, Cool Ju :cool: Dream Ur Destiny -- modified at 4:07 Friday 10th February, 2006

Try this : CString csCommand = "C:\\WINDOWS\\system32\\mspaint.exe c:\somewhere\sample.bmp"; DoExecCommand( csCommand, TRUE ); BOOL CMyDialog::DoExecCommand( CString csCommand, BOOL bWait ) { STARTUPINFO si; ::ZeroMemory(&si, sizeof si); PROCESS_INFORMATION pi; ::ZeroMemory(&pi, sizeof pi); char* pszCmd = csCommand.GetBuffer(0); BOOL bResult = CreateProcess( NULL, // pointer to name of executable module pszCmd, // pointer to command line string NULL, // process security attributes NULL, // thread security attributes FALSE, // handle inheritance flag NORMAL_PRIORITY_CLASS, // creation flags NULL, // pointer to new environment block NULL, // pointer to current directory name &si, // pointer to STARTUPINFO &pi // pointer to PROCESS_INFORMATION ); if(bResult) { if(bWait) { DWORD dwResult = WaitForSingleObject( pi.hProcess, INFINITE ); } CloseHandle( pi.hProcess ); } return( bResult ); }
