Printing with the web browser is doubleing up on the first file

Hello All,

In the code that I will post below is what I am using to print out 'x' number of htm files with out prompting the user. It is being used inside a class that is called from an exe that is run nightly.

The main problem is that the htm file that is created first '1.htm' is printed twice and then the htm file that is created last '22.htm' is not printed at all.

I have tried various things like adding loops that just do application.doevents figureing that it will give the browser time to fully load all of the htm files but it doesn't seem to help. It just seems to fix the orginal problem but then it only prints everyother file.

The code below is what I used in the orginal version of this.

Public Sub PrintInvoice(ByVal strInvoiceHTMLFile As String, Optional ByVal strPrinterName As String = "")

' Check file exists
If Dir(strInvoiceHTMLFile) = "" Then Exit Sub

' Set printer
If strPrinterName <> "" Then
m_SetWindowsDefaultPrinter(strPrinterName)
End If

' Load file into WebControl
m_objWebBrowser.Navigate(strInvoiceHTMLFile)

' Wait for WebControl to load the file
Dim status As SHDocVw.OLECMDF
status = m_objWebBrowser.QueryStatusWB(SHDocVw.OLECMDID.OLECMDID_PRINT)
While status <> SHDocVw.OLECMDF.OLECMDF_SUPPORTED And status <> SHDocVw.OLECMDF.OLECMDF_ENABLED And status <> 3
Application.DoEvents()
status = m_objWebBrowser.QueryStatusWB(SHDocVw.OLECMDID.OLECMDID_PRINT)
End While

' Send Print command
' NOTE: This print command using OLECMDEXECOPT_DONTPROMPTUSER, sends to the Windows Default Printer
m_objWebBrowser.ExecWB(SHDocVw.OLECMDID.OLECMDID_PRINT, SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_DONTPROMPTUSER)
Application.DoEvents()

End Sub

zzzzzooc

It may help to provide the loop that prints the files.

Well this line is all I call and it is just above the End Sub of my orginal posting.

m_objWebBrowser.ExecWB(SHDocVw.OLECMDID.OLECMDID_PRINT, SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_DONTPROMPTUSER)

This is what sends the command to print.

I will add that when this Sub is called it is receiving the files in order and only one copy of each. I have walked through it many times and each time the first file is only pasted in the first time and the last file is passed in as well.

Try this use timer

Option Explicit
Private Sub Timer1_Timer()
Timer1.Enabled = False
m_objWebBrowser.Navigate strInvoiceHTMLFile
End Sub

Private Sub m_objWebBrowser_DocumentComplete(ByVal pDisp As Object, URL As Variant)
Debug.Print pDisp
If (pDisp = m_objWebBrowser) Then
m_objWebBrowser.ExecWB(SHDocVw.OLECMDID.OLECMDID_PRINT, SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_DONTPROMPTUSER)
End If
End Sub

Public Sub PrintInvoice(ByVal strInvoiceHTMLFile As String, Optional ByVal strPrinterName As String = "")

' Check file exists
If Dir(strInvoiceHTMLFile) = "" Then Exit Sub

' Set printer
If strPrinterName <> "" Then
m_SetWindowsDefaultPrinter(strPrinterName)
End If

' Load file into WebControl
Timer1.Interval = 1
Timer1.Enabled = True

End Sub
