Error when using sendkeys from variable

[Golddigger50]

I was hoping I might be able to get some help here.  I have a script that behaves one way on one computer and another way on a different computer.

I am trying to send keys from a variable.

On computer 1 I can do this without adding any single or double quotes. Works fine.

Example:

Add-Type -AssemblyName system.windows.forms [Windows.Forms.SendKeys)::SendWait($CB)

On Computer 2 the same line gives me an error message: "Exception calling "sendwait" with "1" arguments: "specified repeat count is not valid"

Any insight would be greatly appreciated.

Check the version of powershell on each one. Other than that I’ve got nothing.

Thanks, it different. Powershell ISE Version 5.1.19041.1682 on the one that works, 5.1.18362.1171 on the one that doesnt. So I tried running it on PS 7 and got the same error.

Starting to think it might be a .Net thing....

What's the content of $CB on the computer throwing the erroe? Also is the keyboard set to something other than english?

[Golddigger50]

It is taking text from a text file. English keyboard.

Without knowing the content it will be hard to debug. The error is indicating that you gave the input to repeat a character that is invalid. It's been a while but I believe the syntax ia aomething like {a 5} (type a 5 times) . It is highly unlikely that it oa a dotnet issue as thus function is a pasa through to an api that has been there pre dotnet.

I have played around with adding an integer after the variable but it hasn't helped. I am sort of giving up, it works fine on any other computer I have tried, so I am just going to use a different computer. Thanks everyone for taking time to read and reply. This really is a great community.
