Hi Friends,

I need help on PowerShell. I have one form in that form I am giving some inputs and in submit keeping those data in text files. And at the same time I am executing on .exe (any exe file) file so here is my problem I need to assign those text files data to controls of the currently executing exe. Example while executing the exe file it’s asking you company name, Product name etc. So I have kept those data in somewhere like DB or text file and I need to assign to those control. Please help me how to do. My team mate told it’s possible through PowerShell, but I don’t know how to access those control through PowerShell or .net code also. Please help me for the same.

Thanks
Santosh
