Web Browser Control will not print contents in a class library

Question

2.00/5 (1 vote)

See more:

I have a class library and in this class library I create a web browser control, add html to it and then call the print function.

This doesn't seem to print anything and I wonder if someone could help me?
Doing this as a windows application seems to work fine however as soon as I convert it to a class library it doesn't seem to like it.
I heard (as I was searching for an answer) that in a class library you cannot print from a web browser control.

If this is the case how could I accomplish (an alternative way) the same task of printing an html page?

Here is my code:

VB

Private Function StartPrint(ByVal htmlstring As String) As Integer
     Try
         Dim objbrowser As New WebBrowser
         objbrowser.DocumentText = htmlstring
         objbrowser.Print()
         objbrowser.Dispose()
         Return 0
     Catch ex As Exception
         Return -1
     End Try
 End Function

Thank-you.

Solution 1

The WebBrowser control MUST be put on a form in order to work.

I actually tried placing the WebBrowser control on a form, and then in the properties of the solution changed it to a class library. Still it didn't work.

Have you got any alternative solutions? (I.E. Not using a WebBrowser control - something else and be able to keep it as a class library but be able to print out websites/webpages/html ?)

Was this library used in a Windows Forms app and was the form you put it on visible?? If not, it's not going to work.
