AutoHotkey: WinMaximize with Instr

Hello experts,
I would like to understand why winmaximize works in some case and not in other case.

WinMaximize is applied as followed:

^+F12::
If(WinActive("ahk_exe chrome.exe"))
{
	WinMaximize
	Return
}
Else
  MsgBox,4144,Error,Google Drive is not the active window
Return

Open in new window

However it doesn't work as followed:

^+F12::
WinGetActiveTitle,Title
If (InStr(Title,"Google Drive"))
{
	WinMaximize
	Return
}
Else
  MsgBox,4144,Error,Google Drive is not the active window
Return

Open in new window

Thank you for your help.

Hi Luis,

This is well-known issue with AutoHotkey scripts and is documented here:

https://www.autohotkey.com/docs/commands/WinMaximize.htm

Note this comment (copied here under "Fair Use"):

If a particular type of window does not respond correctly to WinMaximize, try using the following instead:

It then proceeds to offer this code:

PostMessage, 0x112, 0xF030,,, WinTitle, WinText  ; 0x112 = WM_SYSCOMMAND, 0xF030 = SC_MAXIMIZE

Open in new window

Give that a spin. Regards, Joe

Sorry for my ignorance but I don't understand the logic. Put instead of WinMaximize windows the line recommended?

^+F12::
WinGetActiveTitle,Title
If (InStr(Title,"Google Drive"))
{
	PostMessage, 0x112, 0xF030,,, WinTitle, WinText  ; 0x112 = WM_SYSCOMMAND, 0xF030 = SC_MAXIMIZE
	Return
}
Else
  MsgBox,4144,Error,Google Drive is not the active window
Return

Open in new window

I tested the following and it works.

^+F12::
WinGetActiveTitle,Title
If (InStr(Title,"Google Drive"))
{
	PostMessage,0x112,0xF030,,,%Title%
	Return
}
Else
  MsgBox,4144,Error,Google Drive is not the active window
Return

Open in new window

Thank you for your help.
