Inconsistent behavior of ShellExecute in printing pdf and htm files, using VB6

Help, please

I use the following to print documents from a VB6 app runing on Windows XP.

            ShellExecute hwnd, "PRINT", myPath2File, vbNullString, vbNullString, 0

If the document is .pdf, the printing is initiated, which is what I want.
If the document is .htm, the printers dialog box opens, which is not what I want.

Is there a way to avoid the printers dialog box, please?

Thanks Denago

I've tried the command in various ways, but I've succeeded only in generating error messages. This problem may well be my lack of knowledge. I've looked at KB 164787, and I'm unclear just how and from where I should run the command.

Please could you add a line or two to show how to handle it within VB6?

Thank you

Each application has it's own "Print" functionality. IE's "Print" just includes the dialog whereas Acrobat's doesn't. The "rundll32.exe" shortcut is basically the same as right-clicking on an HTML file and selecting "Print".

You should just use SendKeys() to automate the Print Dialog window. It's not "neat" but it should do the job.

Neat SendKeys() may not be, but functional it definitely is! Thank you.

This is what I used

     ShellExecute hwnd, "PRINT", sPathFile, vbNullString, vbNullString, 0
     Wait 5
     SendKeys "%(P)"

The Wait, set abitrarily at 5 sec, is needed to give the Print dialog box time to materialize. It does so fleetinglly. Then the automation proceeds as desired.

Acknowledgement, too, to Denago, for the alert to rundll32.exe, which I can see uses for in other ways.
