Hi, I have started a multi-form project and every time I send a message to the main form, the child form closes. What I need to be able to do is keep the child form open and append a new message to the line below on the richtextbox on the main form. Is this possible? Thanks so much!

The parent form is not accessible from the child by any normal means. Pass the control as a parameter to the child and add the text to the control object passed.

Also you can access the mainform's variables directly as they should be in scope. Just refrence the variable for the textbox you want to write to. If it is called "$richtextbox1" then you can access it like this:

$richtextbox1.AppendText('my message')

If the dialog is aborting then you may have issues with your code such as bad syntax after the output or it may be throwing an exception.

Thanks jvierra! The reason I'd like to do this is because I will be presenting what is on the main form so I don't need to touch it per say. The objective is to be able to use the child form on a different screen (2 screen setup) and update (append) the next line of text to the richtextbox on the main form. It looks like this is only possible to update the main form when you close out the child form

[jvierra]

No. You can update controls on the main form by passing the control to the child as a parameter. We do it all of the time.

Got it to work, thank you! I just have one more final question about the form.

I'm currently appending the text from the child form to the main forms richtextbox. I need to center the newly appended text both horizontally and vertically in the box, so it is literally in the center of the richtextbox. The text above it needs to auto scroll up when the new text is added. Is this something that can be accomplished? Thanks again!

[jvierra]

Not really. You would have to code all of that and I wouldn't use an RTB,

Here is how to create a scrolling label control.

Thanks jvierra, what would you recommend using on PS studio instead of richtextbox for displaying this data? Looks like I'm going to have to forget the auto-scrolling. When I click submit on my child form, I delete clear the previous string in the textbox and insert the next one however I need to this to just be horizontally centered within the form itself, whether its a richtextbox or not. It there anything in the toolbox in PS studio that can display this string within my form? Thank you
