Sorry for the C++ answer....

Are you using VB.NET or VB6 ? VB.NET has an excellent class library, including classes for text files, which allow you to read line by line ( so you can keep line 4 ). VB6 kind of sucks, I don't know what you'd do there.

Given your comments below, your solution is fragile. What you should do is build a hashtable of names to full address details, so when the user clicks on a name, you look it up in the hashtable. What if someone changes the file while your exe is open ?

In VB6 use
fnum = FreeFile
Open strfile for Input As #1
strfile = Input$(LOF(fnum, #1)

search from the net.

Hi all,

I am using the following line to print a file in my VB .NET app.

Shell("Notepad.exe /p " & lsFile, AppWinStyle.Hide)

This way I don't have to worry about drawing out a PrintDocument and wordwrap is handled for me by Notepad.

I was wondering if there is a way of invoking the Print Dialog for Notepad through a command line argument? Or someway of passing the printer name to the Notepad command line argument /pt filename printer ?

Any suggestions? Thanks

I think the command lines for Notepad looks like this so:

/P <filename> print filename
/PT <filename> <printername> <driverdll> <port>

somthing like this:

Shell("Notepad.exe /PT " & lsFile & " <printername> <driverdll> <port>", AppWinStyle.Hide)

MSDN: Pathname
Required. String. Name of the program to execute, together with any required arguments and command-line switches. Pathname can also include the drive and the directory path or folder.

I'm still looking around for an answer, but do you know if the driverdll and port are required as a command line argument?

Also, is there some way to get that information from the PrintDialog control in VB.NET?

All I could find in the properties is: PrintDialog1.PrinterSettings.PrinterName

But that doesn't pass to the command line properly...or perhaps I am doing something wrong? Confused | :confused:

The printer name is exactly how it is shown in the printers and faxes control panel under properties for the printer settings.

example: mine is "EPSON Stylus Photo 785EPX"

Run this from the command line in a dos window and it will give you the rest of the info you need:

RUNDLL32 PRINTUI.DLL,PrintUIEntry /Xg /n "<put your printer name here>"

Ok, Anonymous I think I got it now,
to use the /pt switch everthing must be in quotes(") past the switch.

Here's how i got it to work:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim lsFile As String = "NotePad.exe /pt " & """c:\results.txt""" & """Okidata ML 320 Turbo/D (IBM)""" & """LPT1:"""
Debug.WriteLine(lsFile)
Shell(lsFile, AppWinStyle.NormalFocus)
End Sub

My application works fine on my computer, but when I try to run it on someone else computer I get the following error.

An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in system.windows.forms.dll
Additional information: Class not registered

This error occurs at a line within the Windows Form Generated Code. My form contains an Adobe Control for ActiveX 1.3.

CType(Me.PDFViewer, System.ComponentModel.ISupportInitialize).EndInit()

Can someone point out how to fix this COMException? Or point me in the right direction to trouble shoot this error?

Re: Help: System.Runtime.InteropServices.COMException

It looks like the COM Component is not registered (Your Adobe ActiveX Control)

You'll need to register it from a command line like: regsvr32 <ControlName>

You can't put a variable in two classes. You can share it via a third class, or pass it between the two. If you use a third class, you need to pass an instance of that class, or make it static.

You can read through each line of txt file like this.

Dim sr as new StreamReader(filepath)
Dim foo as string
Do while sr.Peak() > -1
foo = sr.readline()
Loop

sr.DiscardBufferedData()
sr.Close()
sr = nothing

Also checkout the StreamReader Class at

I haven't seen any pure vb snmp trap code.

Most folks use a commercial snmp activex control.

But, here's some places to start if you realy want to build your own.

Simple Network Management Protocol (SNMP) is a widely used protocol for monitoring the health and welfare of network equipment (eg. routers), computer equipment and even devices like UPSs. Net-SNMP is a suite of applications used to implement SNMP v1, SNMP v2c and SNMP v3 using both IPv4 and IPv6.

SNMP Packet Library
The SNMP Packet Library is a C++ library for encoding and decoding SNMP packets. Extremely easy to use. Create those useful SNMP applications without worrying about the underlying protocol details. Includes classes to support UDP tranmission and a Poller class with asynchronous callbacks
