using ShellExecute to close...
-
Hi, i am using ShellExecute to open an image. The image is opened using Windows Picture and Fax Viewer. Now, I have a button, in my dialog(the UI). I want to close the Windows Picture and Fax Viewer, got any idea? here's my code... please help. its kinda urgent... been stuck on this for 3 days... googled it, but nopthing relevant came out. void CDesignDlg::OnImage() { // TODO: Add your control notification handler code here CFileDialog m_ldFile(TRUE); { if ( ! onStart ) { m_button.SetWindowText("Start Image"); } else { m_button.SetWindowText("Stop Image"); } onStart ^= 1; // make onStart 0, or 1 respectively } if (onStart==0){ if (m_ldFile.DoModal() ==IDOK) { CString abc= m_ldFile.GetPathName(); SHELLEXECUTEINFO tiff; tiff.cbSize = sizeof(SHELLEXECUTEINFO); tiff.fMask = NULL; tiff.hwnd = NULL; tiff.lpVerb = "open"; tiff.lpFile = abc; tiff.lpParameters= NULL; tiff.nShow = SW_SHOWNORMAL; tiff.hInstApp = NULL; tiff.lpIDList = NULL; tiff.lpClass = NULL; tiff.hkeyClass = NULL; tiff.dwHotKey = NULL; tiff.hIcon = NULL; tiff.hProcess = NULL; tiff.lpDirectory = NULL; int ReturnCode = ::ShellExecuteEx(&tiff); UpdateData(TRUE); }} else { //what should be put here??? } }

I think killing the process might do the trick. To do this you need the process ID. One of the ways to obtain it is:
int ReturnCode = ::ShellExecuteEx(&tiff);
// Get the pid
DWORD pid = GetProcessID(tiff.hProcess);....
To kill the process call:
KillProcess( pid );
Let me know if this did the trick :)

You should send the WM_CLOSE message to the
Windows PictureandFax Viewermain window. :)If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

Do you have the proper include's? Try:
#include Windows.h
or
#include Winbase.h
Also as CPallini suggests below, you can try sending a WM_CLOSE to the window... Yo get the handle from the ShellExecuteEx method (in tiff.hwnd)
WM_CLOSE to window.. for example? I tried, but keep getting different error, went to the library of SHELLEXECUTE, all said is optional for hwnd... so i cannot get any example... yup. i do have the proper includes...

Foret the hwnd - I was wrong anyway :D Getting back to GetProcessID: Try reading about the function in MSDN - all the info is there. If your includes are ok maybe you're missing a lib? Did you link to Kernel32.dll? Select your project propertied, go to Linker -> Input -> Additional Dependencies And type in Kernel32.dll.

yup i know about the site... I am using Visual C++6 there is no additional dependencies there... :( i try puting it in object modules, but an error came out saying cannot open Kernel32.dll

Are you kidding? AFAIK "undeclared identifier" error has nothing to do with the linker. :)
