AutoCAD doesn't respond to CreateProcess screen size instructions

I am using the CreateProcess API call to launch AutoCAD but when I supply the screen dimensions I want AutoCAD to start in, it just comes up at whatever size it was closed in. I can resize the application after it's up and running, so I must be doing something wrong. Any ideas? Here's the chunk of code I'm using:

Code:

With sInfo
.dwFlags = STARTF_USESIZE
.dwX = (Screen.Width / Screen.TwipsPerPixelX) / 2
.dwY = ((Screen.Width / Screen.TwipsPerPixelX) / 2) - 8
.dwXSize = (Screen.Width / Screen.TwipsPerPixelX) / 2
.dwYSize = (Screen.Height / Screen.TwipsPerPixelY) / 2
End With

sInfo.cb = Len(sInfo)

' ActMsg "Launching AutoCAD"

lSuccess = CreateProcess(lpApplicationName:=sNull, _
lpCommandLine:=strApptoRun, _
lpProcessAttributes:=ByVal 0&, _
lpThreadAttributes:=ByVal 0&, _
bInheritHandles:=1&, _
dwCreationFlags:=NORMAL_PRIORITY_CLASS, _
lpEnvironment:=ByVal 0&, _
lpCurrentDirectory:=strStartDir, _
lpStartupInfo:=sInfo, _
lpProcessInformation:=pInfo)

TIA

AutoCAD does not like to be told what to do in this manner.

 

Hi VBA,

Thanks for the info, I figured as much but just thought I'd check!

Thanks again,
Todd
