Tried dialog hidden technique from dlgboxtricks but it didn't work....
-
Hi, I am trying to make Nishant Sivakumar - "Using global hotkeys" start hidden: http://www.codeproject.com/system/nishhotkeys01.asp I have added the hidden modal code from Nishant Sivakumar - "Some handy dialog box tricks, tips and workarounds ": http://www.codeproject.com/dialog/dlgboxtricks.asp It compiles, but it doesn't become hidden. Changes to the "Using global hotkeys" project I made: In "HotKeyTestDlg.cpp" I added: void CHotKeyTestDlg::OnWindowPosChanging(WINDOWPOS * pos) { if(!visible) pos->flags &= ~SWP_SHOWWINDOW; CDialog::OnWindowPosChanging(pos); } and added "visible = FALSE;" to: CHotKeyTestDlg::CHotKeyTestDlg(CWnd* pParent /*=NULL*/) : CDialog(CHotKeyTestDlg::IDD, pParent) In "HotKeyTestDlg.h" I added "BOOL visible;" to protected under: class CHotKeyTestDlg : public CDialog This wouldn't compile "error C2509: 'OnWindowPosChanging' : member function not declared in 'CHotKeyTestDlg'" till I added "void OnWindowPosChanging(WINDOWPOS * pos);" to public under: class CHotKeyTestDlg : public CDialog So it now compiles and runs, but it doesn't start hidden.

pos->flags &= ~SWP_SHOWWINDOWstatement is actually executed? If not, isvisiblebeing changed toTRUEsomewhere? Do you have any calls toShowWindow()?

MFC is something I have been told to avoid at all costs and just go and learn .Net, so my knowledge of MFC is quite limited.

It is not executing, I tried both: void CHotKeyTestDlg::OnWindowPosChanging(WINDOWPOS * pos) { if(!visible) { pos->flags &= ~SWP_SHOWWINDOW; MessageBox("This executed"); } CDialog::OnWindowPosChanging(pos); } void CHotKeyTestDlg::OnWindowPosChanging(WINDOWPOS * pos) { pos->flags &= ~SWP_SHOWWINDOW; MessageBox("This executed"); CDialog::OnWindowPosChanging(pos); } both didn't bring up the message box. visible is always false for the entire length of the program, I haven't modified it anywhere and it isn't being modified by anything.

You failed to add
ON_WM_WINDOWPOSCHANGING()to the dialog's message map. This is something that ClassWizard would have handled for you!

I added it manually and it worked. I was looking thru the ClassWizard and unless I added in ON_WM_WINDOWPOSCHANGING() manually it wouldn't have appeared.... For future reference how should I use ClassWizard todo something like this.... Thanks for your help.

ClassWizard has somehow been set to only show dialog-related messages. Click the Class Info tab and select Window in the Message filter: combobox. Back on the Message Maps tab, you should see WM_WINDOWPOSCHANGING in the list of messages.
