VS 2005 - Throw An Exception When Print To The Printer Using The PrintDocument
Oct 29, 2009
When I print to the printer, using the PrintDocument, I want it to be able to throw an exception if there is a problem. Currently, if I print to a printer that has a jam, is offline, or doesn't even exist, VB still thinks it printed fine. I never get an error. How can I have the printer report back to my program so that if I print to a printer that doesn't even exist, it wont let me do it? I just tried adding a LPT1 printer to my computer (and there is no local printer). I called it some random printer and installed some random driver. Then used my program to print to that printer and never got an error.

It is possible to catch an exception and throw a new exception which wraps the first exception as an inner exception: [URL] Also, if I call a function and it throws a certain error, but I catch it, will the calling code's catch handler execute? If so, and it is of a higher exception type, is this not wrapping the exception? eg I can throw exception ex of type IndexOutOfRange, log it but rethrow, catch a higher up exception and do something, or I can throw a new exception and wrap an inner exception like:

Do you know of a way of knowing the lenght a string will ocupy on a .DrawString using PrintDocument?
What I want to do is to break up a string in case it won't fit on the page, do not sugest to search for the lenght of the string itself because I am not interested in the number of characters, as you may know, PrintDocument "draws" the text on the page so on proportionate fonts, the number of characters is independent on the lenght of the output.
this is the line that prints the text:
vb.net
e.Graphics.DrawString(strText, New Font("Arial", 12), Brushes.Black, 10,10)
Of course I could use monospaced fonts like courier or the like but... well, I don't want to.

I ran into an interesting dilemna today. I have a function that handles information and checks for duplicate values, then returns the next number that is not a duplicate. So, I have something like this:
Public Function GetNextNonDuplicateNumber(NumberToCheck as Long) as Long
//the non-duplicate the function will return
Dim NonDuplicate as Long
'duplicate
If CheckForDuplicate(NumberToCheck) = True Then
Throw New DuplicateException()
[Code] .....
As you can see, I want to handle the exception specifically, but I also want to throw it when I'm done because I want to alert other code outside the function. The problem is that simply throwing it exits out of the function with a null value.

1) How is ON ERROR GOTO -1 used? I don't understand the help text.
2) ON ERROR seems to be deprecated. What is the recommended Try...Catch replacement for ON ERROR RESUME NEXT. ie. where I have a series of commands, any of which may throw an exception, and I want to ignore all exceptions yet attempt every command?

while my first .net steps I want to understand and test the Method
Private Sub MyApplication_UnhandeledException in ApplicationEvents.vb.
But if I throw an exception the IDE stops and says "unhandled exception" and gives solution tips.
Is it possible to switch off those exception warnings and run through the unhandeled exception handling in ApplicationEvents.vb ?

If I have an existing exception object (I'm not in a catch block, I just happen to have been given an exception object), is there any way (re)throw it while preserving it's stack trace?
The context for asking is that I'm writing a RunWorkerCompleted handler. If an error happened while running the background task, then this will have shown up in the Error property of the RunWorkerCompletedEventArgs. To keep the code simple I want to use the same error handling code to trap this, or any error that happens later during the handler. That means I need code like this:
Private Sub OnDone(ByVal sender As Object, ByVal e As RunWorkerCompletedEventArgs)
[Code]...
I don't think that using an InnerException here (ie. saying something like Throw new Exception(ex)) will work because then I have the problem that my Catch block has no way of knowing whether the exception it's supposed to be handling is the outer one or an inner one. StackOverflow seems to have various similar questions, but I've not found anything that describes this particular situation.

Having problems with null dates in a mysql table. Have eventually found out that I can store a 'null' date in mysql as "0000-00-00" and I can run the 'insert' command to add a record to the mysql table. When I check on mysql workbench I can see the row has been inserted correctly and the date shows as "0000-00-00".However...When I try to load the table into a datagridview, I get an error = mysql Conversion Exception was unhandled = "Unable to convert MySQL date/time value to System.DateTime".

I know this says not for VB6, however there does not seem to be a forum for VB6. I have VB6 and Access. I want to print to a printer.There is a Printer class with many properties such as line draw, page, orientation, EndDoc etc. It does not have a print option. All documentation I have been able to find is like this
Dim printer1 as printer
set printer1 = Priinters(2)
printer1.print "This is a test line." ' This does not work, error message "Runtime error '438'" "Object doesn't support this property or method." also I get the same error message for printer1.EndDoc even though it is listed.

I am using the PDF control from Adobe to view and print pdf documents and works well. I am setting the default printer prior to printing and then call Print. I need to change this where I do not change the default printer due to a conflict with another program. But I cannot see where I can set the printer only for printing from this control. I do not want to use a dialog because it does have a PrintWithDialog option. Is there any other way to do this without the dialog?

Does someone has already printed to a printronix printer (serie t5000r) using .NET (visual basic or C#) ? We already have the file (txt) with the code to generate the label until I know the code it's PGL. What've done was to use file.copy() to send the file to the LPT1 port (we use this method with Zebra printers and it works fine) but the printer print plain text instead of the label with it's format (barcode, titles, etc).

I am an old Quick Badic Programmer - I was pretty good. VB 2010, and the .NET framework, are NOT improvements! Moving on, all articles I read about printing are focused on VB 6, and little or nothing about VB 2010 or .NET I don't care about the power pack, since it isn't any better than .NET - so how about a ground-up tutorial on how to print to the printer for someone who is being driven crazy by Microsoft's total F-UP of BASIC.

I have a program needs to print directly to a Zebra TLP 2844-Z barcode printer.
I tried the codes in [url]... but an error occurred when i run it, as follows:
A call to PInvoke function 'test!test.RawPrinterHelper::OpenPrinter' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.
May I ask if any one has any other idea of printing directly to printer in VB2005?
