I've been trying to determine where these extra messages are coming from and I'm fairly sure it is TranslateMessage()

My background isn't in desktop programming so this stuff is a bit over my head.

Are keyboard accelerators a solution, or is there some way to skip TranslateMessage? I can't determine how to use either since they both appear to require you to have control over the message loop itself of the program/thread for which you are posting messages.

Code:
' VB Example Code (Values used in place of param builders for simplicity)

' KeyDown
PostMessage(WindowHandle, WM_KEYDOWN, &H11, &H1D0001)
PostMessage(WindowHandle, WM_KEYDOWN, &H33, &H40001)

' KeyUp
PostMessage(WindowHandle, WM_KEYUP, &H33, &HC0040001)
PostMessage(WindowHandle, WM_KEYUP, &H11, &HC01D0001)


MANUAL INPUT
P WM_KEYDOWN nVirtKey:VK_CONTROL cRepeat:1 ScanCode:1D fExtended:0 fAltDown:0 fRepeat:0 fUp:0
P WM_KEYDOWN nVirtKey:'3' cRepeat:1 ScanCode:04 fExtended:0 fAltDown:0 fRepeat:0 fUp:0
P WM_KEYUP nVirtKey:'3' cRepeat:1 ScanCode:04 fExtended:0 fAltDown:0 fRepeat:1 fUp:1
P WM_KEYUP nVirtKey:VK_CONTROL cRepeat:1 ScanCode:1D fExtended:0 fAltDown:0 fRepeat:1 fUp:1

PROGRAMMATIC INPUT
P WM_KEYDOWN nVirtKey:VK_CONTROL cRepeat:1 ScanCode:1D fExtended:0 fAltDown:0 fRepeat:0 fUp:0
P WM_KEYDOWN nVirtKey:'3' cRepeat:1 ScanCode:04 fExtended:0 fAltDown:0 fRepeat:0 fUp:0
P WM_KEYUP nVirtKey:'3' cRepeat:1 ScanCode:04 fExtended:0 fAltDown:0 fRepeat:1 fUp:1
P WM_CHAR chCharCode:'0033' (51) cRepeat:1 ScanCode:04 fExtended:0 fAltDown:0 fRepeat:0 fUp:0
P WM_KEYUP nVirtKey:VK_CONTROL cRepeat:1 ScanCode:1D fExtended:0 fAltDown:0 fRepeat:1 fUp:1


All I want is for that red line to not appear Sad
