GetCurrentConsoleWindowRect

This uses the inbuilt compilers in Windows 10 - there are three VB.NET compilers and three C# compilers - just copy each text file into the same folder and double click the batch file to make the program.
Window Manipulation Posts

Use this to get the current console rect.

REM GetCurrentConsoleWindowRect.bat
REM This file compiles GetCurrentConsoleWindowRect.vb to GetWindowRect.exe
REM GetCurrentConsoleWindowRect.exe reports on console's windows position
REM To use 
REM GetCurrentConsoleWindowRect
REM EG
REM GetCurrentConsoleWindowRect
REM
REM Change /target:exe to /target:winexe and uncomment the 
REM msgbox line in main file to make it a non console program
"C:\Windows\Microsoft.NET\Framework\v4.0.30319\vbc.exe" /target:exe /out:"%~dp0\GetCurrentConsoleWindowRect.exe" "%~dp0\GetCurrentConsoleWindowRect.vb"
