Print RTF document with PrintDocument and PrintPageEventHandler

[NikoWenz]

Hi Community,

my goal is to print a rtf document with the .net Framework. As a reference i used the MSDN article.

The problem is that the constructor PrintPageEventHandler needs a reference to a method. In the source code this is PrintPageEventArgs, but in LabVIEW i cant connect the ReferenceOut of PrintPageEventArgs and method.

I made some changes, but still i dont know what need to be connect with the method 😞

Another try 😄
This time the Programm works but the document i print is empty. Is the position of the graphics wrong or does anyone know how to print properly with PrintDocument?

This is an old thread, but for whomever wanders here looking for using .net to print from LabVIEW -

To do the above, refer to https://forums.ni.com/t5/Developer-Center-Resources/Register-Callback-VIs-for-NET-Events-in-LabVIEW/...

There are also examples in LabVIEW itself (search by .net keyword).

You need to create a second VI that will act as a callback to your printPage() event.

In that vi you will need to use "Event Data -> e -> Graphics" methods to provide information to print.

Attached is an example that prints an image from file to a PDF. To print your RTF you will need to replace "Image.FromFile" and "DrawImage" to your StreamReader and corresponding drawing functions.
