Reply with quote

say, I have following content on clipboard:

Code:

HKEY_CURRENT_USER\Console\%SystemRoot%_system32_cmd.exe

and I need to pass this to a console program as-is (without expanding the %SystemRoot% environment variable). I'm testing this will following code:

Code:

Run, cmd.exe /k echo "%clipboard%"

this will show

Code:

"HKEY_CURRENT_USER\Console\C:\WINDOWS_system32_cmd.exe"

If I replace the string first:

Code:

stringreplace, rp, clipboard, `%, `%`%, A

Then it shows:

Code:

"HKEY_CURRENT_USER\Console\%C:\WINDOWS%_system32_cmd.exe"

The thing is dos command needs double % to escape it, while AHK needs `% to escape it; and I'm not sure how to do escape this here.

Thanks.

Thanks!

I'm quite new to ahk and wasn't aware of #NoEnv.

Also, to enclose in quotes, I need to put ^ before quotes too:

Code:

Run, cmd.exe, /k echo ^"%rp%^"
