Help Needed in working with windows API

  I am working on an application where i need to fetch values for some of the components developed in C++. For example I need to fetch the text which is displayed dynamically on an AFX title bar. I used the following dll method to fetch the text displayed in title bar but was unsuccessful since there is no text in wndcaption.(The below code is just an example)



Sub Call_SendMessage_FromDLL



'Handle = Sys.Process("notepad").Window("Notepad", "sanjay.txt - Notepad", 1).Window("Edit", "", 1).Handle

MessageID = 13 'WM_GETTEXT

MaxTextLen = 1000



' Defines the dll type

Set Def_DLL = DLL.DefineDLL("USER32")



' Registers the function type in TestComplete

Def_DLL.DefineProc "SendMessageA", vt_i4, vt_i4, vt_i4, vt_lpstr, vt_i4



' Creates an alias for SendMessageA

Def_DLL.DefineAlias "SendMessage", "SendMessageA"



Set LpStr = DLL.New("LPSTR", 256)



' Loads the dll

Set Lib = DLL.Load("USER32")



' Calls the function from the DLL

Lib.SendMessage Handle, MessageID, MaxTextLen, LpStr



Log.Message LpStr.Text

End Sub



And when i spoke to the developer they told :The text in the Title bar are drawn using GDI of MFC. The methods such as DrawText are used. Now I dont know which method should I use to fetch the text (which is written using Draw Text Method). Kindly help
