Printing in VB.NET

[jim watterson]

I'm trying to print a diagram vb.net VS2013 8.1 app. The statement;

Await Diagram1.PrintingService.RegisterForPrinting()

produces an error - expression does not produce a value.

Removing the await stops the error and allows the app to show the print dialog but then the print preview fails.

Any ideas?

fter further experimenation I have found that:

I have Diagram1PageSettings = Nothing - which I copied from the examples or documentation. If remove this and add

Diagram1PageSettings .PageWidth =500

Diagram1PageSettings .PageHeight=500

A reversed out block is drawn on top of my diagram corresponding to this size with the line colours inverted. This block then prints but is not what I want.  

All I want is to print my diagram as I see it. The documentation says that PageWiidth & PageHeight should be set by the contents?

Hi Jim,

Sorry for the inconvenience caused.

Regarding “Printing in VB.NET” to your reported scenario, we have created simple sample to meet your requirement. Currently, we don’t have a support to directly print the Diagram content. We have used Pagesettings to print the Diagram with specified Size. We will update the documentation with necessary information in future. Please refer to the attached sample.

Please let us know if you have any concerns.

Regards,

Thank for your response. I am trying to fit the diagram onto the page if possible and only go to another page if it won't fit. 

If I could set the PageSettings to the printable area of the page then this would work but I cannot see how to retrieve this because i never have access to the printer context - is there an event I can override during the preview call to get the page size?

When I print anything it is hard up against the left and top in the preview. When I print the top and left are chopped off by a few pixels. PrintMargin has no effect. I've set a colour and thickness for the border but it is never displayed. I do not understand what OffPageMaxMargin is for.

Hi Jim,

We have analyzed your query. We have provided some virtual method to override the printing functionality in PrintingService. The Print Margin property is used to define the Margin for PageBreaks.

Please refer to our online help documentation link for more details about printing.

It would be better for us, if you provide more details (sample, document or video) to represent your requirement. This helps us to serve you better.
