Printing.
-
Hi I am currently working on a app that prints a html invoice using Internet Explorer. as follows
Dim internetExplorer As New SHDocVw.InternetExplorerClass()
Dim webBrowser As SHDocVw.IWebBrowser2 = CType(internetExplorer, SHDocVw.IWebBrowser2)
'// Make the web browser visible. //
webBrowser.Visible = False
'// Display empty page so we have something to manipulate.
Dim noValue As Object = System.Reflection.Missing.Value
webBrowser.Navigate("file://" + fileName, noValue, noValue, noValue, noValue)
Threading.Thread.Sleep(1000)
'// Get access to the webbrowser's document.
Dim htmlDoc As mshtml.IHTMLDocument2 = internetExplorer.Document
Dim o As Object = ""htmlDoc.execCommand("Print", False, o) htmlDoc.close()I read in the documentation that one can set a value for nCmdExecOpt to OLECMDEXECOPT_DONTPROMPTUSER for the dialog. I just can't seem to figure out where to set it. All help greatly appreaciated. Tx

The Thread.Sleep line is of no use. It's making the improper assumption that the page takes, at MOST, 1 second to load. It's better to check the Busy property every so often to know when the browser is ready. You can't use that trick with the .NET version of the WebBrowser control. You have to use the COM server that IE exposes directly to do that. A sample of which can be found here[^]. The code is in C#, but is easily converted to VB.NET using any online code conversion utility or, even better, done by hand.

Thanks for down-voting me, and YES, it DOES answer the original question. You cannot use the .NET WebBrowser control to do what you want. You have to use the unwrapped COM server IE exposes, THEN you can use the technique you described. I even posted a link to a code example showing you exactly how to do it. So, how did that not answer the original post?
