Retrieve traytip text using TTM_GetText message

25 Oct 2013, 08:15

I was looking at some old threads and found this TTM_GetText message which can be used to retrieve tooltip / traytip text.
I attempted to try and solve some of it, but I'm missing something, could anybody tell ?

Code: Select all

TrayTip, % Title:="Title", % Text:="Text"
DetectHiddenWindows, On
wParam:=StrLen(Text)+1
cbSize:=4+4+A_PtrSize+(A_Is64bitOS ? 8 : 4)+16+A_PtrSize+( wParam * (A_IsUnicode) ? 2 : 1 )
FileGetVersion, _WIN32_IE, %A_ProgramFiles%\Internet Explorer\iexplore.exe
If (floor(_WIN32_IE)>=3)
	cbSize+=A_Is64bitOS ? 8 : 4
VarSetCapacity(lParam,cbSize,0)
NumPut(cbSize,lParam,0,"UInt")
NumPut(uFlags:=0,lParam,4,"UInt")
NumPut(hwnd:=A_ScriptHwnd,lParam,8,"Ptr")
NumPut(uId:=0,lParam,8+A_PtrSize,A_Is64bitOS ? "UInt64" : "UInt")
NumPut(Rect_Left:=0,lParam,8+A_PtrSize+(A_Is64bitOS ? 8 : 4)+4,"Int")
NumPut(Rect_Top:=0,lParam,8+A_PtrSize+(A_Is64bitOS ? 8 : 4)+4+4,"Int")
NumPut(Rect_Right:=A_ScreenWidth,lParam,8+A_PtrSize+(A_Is64bitOS ? 8 : 4)+4+4+4,"Int")
NumPut(Rect_Bottom:=A_ScreenHeight,lParam,8+A_PtrSize+(A_Is64bitOS ? 8 : 4)+4+4+4+4,"Int")
NumPut(hInstance:=0,lParam,8+A_PtrSize+(A_Is64bitOS ? 8 : 4)+16,"Ptr")
NumPut(lpszText:=0,lParam,8+A_PtrSize+(A_Is64bitOS ? 8 : 4)+16+A_PtrSize,"UInt")
If (floor(_WIN32_IE)>=3)
	NumPut(lParam_struct:=0,lParam,8+A_PtrSize+(A_Is64bitOS ? 8 : 4)+16+A_PtrSize+(wParam * ( (A_IsUnicode) ? 2 : 1 )),A_Is64bitOS ? "UInt64" : "UInt")
SendMessage,TTM_GETTEXT:=0x0400+56,wParam,lParam, , ahk_id %A_ScriptHwnd%
Text2:=""
Loop, % wParam-1
	Text2.=NumGet(lParam,8+A_PtrSize+(A_Is64bitOS ? 8 : 4)+16+A_PtrSize+A_Index-1,"Char")
MsgBox % Text2
return

Thank you, but I was merely using this to increase my understanding of APIs.
Would it be possible for you to take a look at the code above ?
EDIT : Oh, and sorry for not noticing earlier, but welcome to the forum.

Thanks for the welcome.
I don't understand your code, so I can't help with it.

The text, it's incorrect. No particular error. Just shows up as 0000

  • lpszText is a pointer to a buffer that receives the text.
  • TTM_GETTEXT
    lparam
    Pointer to a TOOLINFO structure. Set the cbSize member of this structure to sizeof(TOOLINFO) before sending this message. Set the hwnd anduId members to identify the tool for which to retrieve information. Allocate a buffer of size specified by wParam. Set the lpszText member to point to the buffer to receive the tool text

Some questions regarding this
Spoiler
Thank you for your help.

EDIT : I have create a table for this structure, if you could just identify the mistake(s) in it, that would be great.

Re: Retrieve traytip text using TTM_GetText message

  1. You need to check whether the application is 64-bit (i.e. A_PtrSize =8).
  2. lpszText is a pointer to a buffer, so its size is A_PtrSize.
  3. *lpReserved and lParam are pointers/pointer-sized, too.
  4. Alignment is not needed as far as the lenght is a multiple of the largest member.
  5. VarSetCapacity(Var, Lenght, 0) will initialize Var with binary zeroes.
Table: The offsets of lParam and *lpReserved do not depend on wParam.

I believe I understood what you mean, but the code still doesn't work. :?:
