print preview for mdi child?

[ethicalhacker]

the code

 PrintPreviewDialog1.Document = PrintDocument1
        PrintPreviewDialog1.ShowDialog()

doesn't work for me
I have a rich text box on the child form and want to print preview its contents
I use

Dim child As frmChild = TryCast(Me.ActiveMdiChild, frmChild)

to declare my active mdi child form.
I have put the print preview dialog control on the mdi parent form.

I'm a big fan of people saying X "doesn't work". That could mean all sorts of things. ALWAYS explain what DOES happen. There's absolutely nothing wrong with any of the code you've posted in and of itself. You perform the printing in the PrintPage event handler of your PrintDocument. You've made no reference to that so we can't say what the problem might be.

print preview for mdi child

Is there any way I can show a print preview for an mdi child rtb's contents?

Thread moved to Printing forum, please post to appropriate forums, there is often a better option than the General ones.

Here's link to the RichTextBoxEx class everybody's using to get what-you-see print of rich text, Getting WYSIWYG Print Results from a .NET RichTextBox

what exactly happens is it shows a blank print preview
Ive attached a printscreen of the output

And what's in your PrintPage event handler?

 

[ethicalhacker]

Private Sub PrintPreviewToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PrintPreviewToolStripMenuItem.Click
        Dim child As frmChild = TryCast(Me.ActiveMdiChild, frmChild)
        PrintPreviewDialog1.Document = PrintDocument1
        PrintPreviewDialog1.ShowDialog()
    End Sub

I have asked you twice now what code is in the PrintPage event handler of your PrintDocument and you have not provided the requested information. You have provided the code that's in the Click event handler of some menu item, but that is not what I asked for and is of no use. Have you even handled the PrintPage event of your PrintDocument? That's where you do the printing so if you haven't then of course nothing gets printed.

 

[ethicalhacker]

no i hadnt handled it so now what do i put in the printdocument printpage event handler to actually print the page?

One option is doing as post 2 in this thread: http://www.vbdotnetforums.com/showthread.php?t=14626
Instead of "getsnap(Panel1)" you can do "getsnap(Me)" to get the image of the form.

here's a good start on what you'll need to know to print using the PrintDocument control:
http://msdn2.microsoft.com/en-us/library/system.drawing.printing.printdocument.aspx

Getting examples isn't hard either, you'll probably want to read up on the Graphics class as well

 

[jmcilhinney]

This is the contents of the Remarks section of the MSDN documentation for the PrintDocument class:

Typically, you create an instance of the PrintDocument class, set the properties that describe how to print, and call the Print method to start the printing process. Handle the PrintPage event where you specify the output to print, by using the Graphics included in the PrintPageEventArgs.

Many of the key words are links to more detailed information too. This is why it's impoprtant to read the documentation for the classes you're using, especially when they don't work as you expect. It will often take you a matter of minutes, or even seconds, to find the information you need.
