Sending %BM_CLICK (again)

[John Tate]

I have been using code like the sample below for several years. Control Send and Control Post to the button works for me. I use it to click a button when double clicking on a selection in a listbox, for example.
It must be part of the Case %WM_Command.

That workis, thanks!, although I never would have figured that out! (The Mak part!)


Tx!

Only works for buttons. For menus and other controls, use:

DIALOG SEND CbHndl, %WM_COMMAND, MAK(DWORD, %IDM_SAVE, %BN_CLICKED), 0

[Scott Turchin]

I thought I had this working, maybe I can't do it?

Problem is- it's never received by the %IDM_SAVE, %IDM_SAVEAS....

          Case %IDM_CLOSE
              If IsTrue Need2SaveFlag Then
                  sTmp = "Save Changes before exiting Y/N?"
                  lResult = MessageBox(ByVal CbHndl, ByVal StrPtr(sTmp), ByVal StrPtr(g_szMine), ByVal %MB_ICONWARNING Or %MB_YESNO)
                  If lResult = %IDYES Then
                      Control Send CbHndl,%IDM_SAVE,%BM_CLICK,0,0
                      Function = %TRUE
                  End If
              End If

          Case %IDM_OPEN
              If IsTrue Need2SaveFlag Then
                  sTmp = "Save Changes before exiting Y/N?"
                  lResult = MessageBox(ByVal CbHndl, ByVal StrPtr(sTmp), ByVal StrPtr(g_szMine), ByVal %MB_ICONWARNING Or %MB_YESNO)
                  If lResult = %IDYES Then
                      Control Send CbHndl,%IDM_SAVE,%BM_CLICK,0,0
                  End If
              End If


          Case %IDM_SAVE, %IDM_SAVEAS
              If LoWrd(CbWParam)= %IDM_SAVE And CbCtlMsg = %BN_CLICKED Then MsgBox "Save programatically pressed"
