covaks Posted April 21, 2007 Share Posted April 21, 2007 If an external program sends a WM_SETTEXT message to my GUI, how do I get the actual text that it is trying to set? $lparam in the code below is a hex value, I want to msgbox the actual text. So, if an external C program has the following line: SendMessage(hwnd, WM_SETTEXT,NULL,(LPARAM)"foo"); I want my message box to say "foo", instead of some hex value. Is that possible? GUIRegisterMsg($WM_SETTEXT,"MyFunc") Func MyFunc($hwndGui, $msgid, $wparam, $lparam) msgbox(1,"",$lparam) return 1 EndFunc Link to comment Share on other sites More sharing options...
piccaso Posted April 21, 2007 Share Posted April 21, 2007 where you able to catch the WM_SETTEXT message? if yes then lparam is a pointer you can use DllStruct stuff to read it there is a function inside sqlite.au3 (should be in your include dir) called __SQLite_szStringRead which shows how to read a zString CoProc Multi Process Helper libraryTrashBin.nfshost.com store your AutoIt related files here!AutoIt User Map Link to comment Share on other sites More sharing options...
covaks Posted April 21, 2007 Author Share Posted April 21, 2007 Thank you very much, that worked. :-) SendMessage(hwnd, WM_SETTEXT,NULL,(LPARAM)"Super Duper"); From a C program will now cause my AutoIT script to pop up a message box with the text "Super Duper". Now I have a way to pass messages back and forth between the two programs. GUIRegisterMsg($WM_SETTEXT,"MyFunc") Func MyFunc($hwndGui, $msgid, $wparam, $lparam) $text = DllStructCreate("ubyte[15]",$lparam) msgbox(1,"",DllStructGetData($text,1)) return 1 EndFunc Link to comment Share on other sites More sharing options...
CoDEmanX Posted February 16, 2008 Share Posted February 16, 2008 So, if an external C program has the following line:SendMessage(hwnd, WM_SETTEXT,NULL,(LPARAM)"foo");I want to send the WM_SETTEXT message from my autoit script to an external application's controls (ThunderRT6). How to do that? Link to comment Share on other sites More sharing options...
