ShellExecute Question. (urgent)
-
Hi all, Can someone tell me how to get the messages from a child window opened with ShellExecute(...) and then respond to them. I tried setting the hwnd parameter to this->m_hWnd from a dialog app.. then i ran a spy++ and didn't see any messages going from the opened web browser back to my dialog app. example. From a Dialog app, i'm opening and html page in Internet Explorer and I need the Dialog app to be able to respond to dialog boxes that IE presents , like error messages and such. It sounds like i should be able to from the API docs... -- MSDN ---------------------------- HINSTANCE ShellExecute( HWND hwnd, LPCTSTR lpOperation, LPCTSTR lpFile, LPCTSTR lpParameters, LPCTSTR lpDirectory, INT nShowCmd ); hwnd [in] Handle to a parent window. This window receives any message boxes that an application produces, such as error reporting. ... --------------------------------- could someone let me know if my understanding of this is wrong. Thanks for any help.. Rick

You are misunderstanding the purpose of the
hwndparameter. When you start a new process, it's off in its own process space, it is not a child of the launching process or its windows.hwndis only used by the shell if an error occurs.hwndis one of you windows, which is used as the parent of error dialogs if any are displayed. --Mike-- If it doesn't move and it should: WD-40. If it moves and it shouldn't: duct tape. 1ClickPicGrabber - Grab & organize pictures from your favorite web pages, with 1 click! My really out-of-date homepage Sonork-100.19012 Acid_Helm -

My really out-of-date homepage Sonork-100.19012 Acid_HelmThanks for setting me straight. Since that obviously won't work, do you know a way to accomplish the task? i.e. open a browser and then monitor it for any dialogs, and then pragmatically ok or cancel said dialog box, so that the user doesn't have to answer his/her self? Thanks again Rick
