@fcassia there are some tools around that let you change the title of a Window.

And there are some commercial cmd replacements that offer multiple windows.

Excellent!. I arrived here by Googling for “CMD.exe souce code” .

I´ve been trying to find a cmd.exe replacement to use on my WinXP SP3 VMs because I often have a dozen open cmd windows inside the VM and need to know which is which, so I thought I´d recompile cmd.exe to update the wndows´ titlebar with the current path.

Before I do that, though, I wonder if perhaps there isn´t a COMSPEC parameter or other standard windows way to achieve this?.

Thanks!

Thks, that made me experiment more with the ReactOS cmd.exe
version You can make the dll smaller by removing the string tables
languages (has no use there) and not using unicode (saves you macro
space) My cmd.dll is now 120 KB and the cmd.exe which uses the dll
is 64 KB (contains 1 string table) Its a perfect replacement for
the old MS version, no incompatibilities discovered yet.

@Ivan: Merci! BTW, I think you would also need to do something to select the correct win station/desktop when you inject this in a service (no interaction with user desktop).

@Rickard: if I understand your question, you want to run a VBA macro in Excel that sends commands to the “Excel-command-prompt”?

The only way I can think of is to use sendkeys and send keystrokes it to the “Excel-command-prompt” window.

This could actually be very useful.
Can you with some VBA script run program in the “Excel-command-promt”?
