Tyler-McDonald-ExcelSignature
"I have a macro built in PowerShell to open the Signature tool for Excel. I am trying to automate inserting a signature block on an Excel report. The macro works as it should, but I can not get sendkeys("~") to work within Excel to simluate clicking the OK button so the signature block is inserted. It does pass the enter key but it passes it to PowerShell." - Solution was to use COM Object interface for excel and leverage the Add signature method
