Re: Text Box clear Error
I repeat - your variable is not set or is not a textbox control.shamir wrote:Still getting the error

The error means that $textboxHomeAddress does not exist in the scope you are in. The most common cause of this is spelling.

Re: Text Box clear Error
As Jim said, $textbox.Clear() is the standard way of deleting text from a Textbox control, but setting the value of the Text property to $null works, too. I just tested it.
I think there's a different problem. The error indicates that the control object doesn't have a Text property (ERROR: The property 'Text' cannot be found on this object... ERROR: + $textboxHomeAddress.Text = $null). Textbox objects have a Text property, so something else is wrong.
I've run into this issue when I accidentally rename an object in the Properties pane so it looks like a different type of object, such as renaming a Form to $textboxInput so I think I'm working with a textbox, and then trying to set a Textbox-specific property, such as ReadOnly, on the Form. To detect the problem, in the Designer, click on each control and check its name in the Properties pane.
If you still need help, let us know.

Re: Text Box clear Error
Ferdinand. THat is not really how it works/fails.
Look at this:
Your suggest is good but as often it is a misspelled name. With PS201x the rename propagates to all references so it would not usually bean issue.
Look at this:
PowerShell Code
Double-click the code block to select all.PS C:\scripts> ($null).Text PS C:\scripts> ($null).Clear() You cannot call a method on a null-valued expression. At line:1 char:1 + ($null).Clear() + ~~~~~~~~~~~~~~~ + CategoryInfo : InvalidOperation: (:) [], RuntimeException + FullyQualifiedErrorId : InvokeMethodOnNullThe error will occur on a null object when calling a method. Use auto-completion. If it doesn't work then the object is null or doesn't exist.
