Disable ClearType on my application
Dear Expert,
How can I disable ClearType anti-aliasing on my application? Can this be archieved using manifest files or normal windows api? The text I don't want anti-aliased is on a label that is located on a usercontrol. The size of the font has to be small and thus the anti-aliasing messes it up.
Thank you for you fast response!

I solved the problem by setting the global font smoothing property at the start of the program and then resetting it at the end. This is not the optimal solution but works well enough.
Here is the code for it:
-- Declares --
Public Declare Function SystemParametersInfo Lib "user32" Alias "SystemParametersInfoA" (ByVal uAction As Long, ByVal uParam As Long, lpvParam As Any, ByVal fuWinIni As Long) As Long
Public Const SPI_GETFONTSMOOTHING = 74
Public Const SPI_SETFONTSMOOTHING = 75
Public Const SPIF_UPDATEINIFILE = &H1
Public Const SPIF_SENDWININICHANGE = &H2
-- In the begining --
If LenB(GetRegString(HKEY_LOC AL_MACHINE , "SOFTWARE\My program\", "FontSmoothing")) <> 2 Then
SystemParametersInfo SPI_GETFONTSMOOTHING, 0, blFontSmoothing, 0
If blFontSmoothing Then
SetRegString HKEY_LOCAL_MACHINE, "SOFTWARE\My program\", "FontSmoothing", "T"
Else
SetRegString HKEY_LOCAL_MACHINE, "SOFTWARE\My program\", "FontSmoothing", "F"
End If
End If
SystemParametersInfo SPI_SETFONTSMOOTHING, False, 0&, SPIF_UPDATEINIFILE Or SPIF_SENDWININICHANGE
-- In the end of the program --
SystemParametersInfo SPI_SETFONTSMOOTHING, (GetRegString(HKEY_LOCAL_M ACHINE, "Software\My program\", "FontSmoothing") = "T"), 0&, SPIF_UPDATEINIFILE Or SPIF_SENDWININICHANGE
SetRegString HKEY_LOCAL_MACHINE, "SOFTWARE\My program\", "FontSmoothing", "NONE"
