Powershell MessageBox

hi,

i add messagebox in powershell script.

i have 2 scripts, first launch script specific credentials.

first script :

start-process powershell -argumentlist "c:\scripts\script1.ps1" -credential (domain\user)

in second script use messagebox :

[system.windows.forms.messagebox]::show("test messagebox" , "information")

when run first script, have error : 

unable find type [system.windows.forms.messagebox]: make sure assembly containing type loaded.

i run command : add-type –assemblyname system.windows.forms but have same error.

if run second script, don't have error.

how can fix this?

thanks.

add-type –assemblyname system.windows.forms - add command top of c:\scripts\script1.ps1

same error.

try add command  to second script.
