CMD: Set buffer height independently of window height

I don't think there is a native batch command that gives independent control of buffer and window sizes. .NET can control both, but I don't think VBScript or JScript can access that functionality. But powershell can :-) See How Can I Expand the Width of the Windows PowerShell Console?

Thankfully, the new settings are preserved in the CMD window when PowerShell exits.

It is important that the window size is always less than or equal to the buffer size. To simplify things, I first use MODE to set both the window and buffer to the desired window size, and then I use powershell to set the buffer size.

Here is a simple conSize.bat hybrid batch/powershell script that takes the sizes as parameters:

@echo off
:conSize  winWidth  winHeight  bufWidth  bufHeight
mode con: cols=%1 lines=%2
powershell -command "&{$H=get-host;$W=$H.ui.rawui;$B=$W.buffersize;$B.width=%3;$B.height=%4;$W.buffersize=$B;}"

To get your desired size, you would simply use

call conSize 100 50 100 9999

I have written a tiny application for Windows that allows to "maximize" the window and buffer. It could be easily extended to allow passing parameters with custom values.

There's a 'ConSetBuffer' binary available that does specifically this, and I've found it to work reliably. It and related console utilities are available at the 'conutils.zip' link on this page.
