i'm having an issue when using the print button on a print preview dialog. im creating a document for customers statements that shows all the debits/credits to their account and a running balance. i have the code creating the document and populating the print preview dialog from an adodb recordset, and it shows the preview not a problem. its when you click the print button in the preview that it throws up an 'EOF/BOF' error on the recordset.
i now understand that the printpage even handles both the preview and the printing so i included coding that closed off the recordset, re-set all the counters and balance totals, re-set the connection string (i have to re-set it because there is the capability of printing only a partial statement, so i have to select all records before the selected date, calculate the balance up to that point, then select all the records from the selected date and use the calculated balance from that point in the statement), then re-open the connection. but this still throws up the error, when the error appears its as if the code isnt resetting the recordset and when it prints its trying to print everything after the last record?
some abbreviated code is below
Public reference_no, qtr, fyear As Integer
Public statement_type, statement, sqlString As String

I've got problems while printing a document.I've got a program that have a small form with options for printing two diferent pages.Here's the There is a Button for printing named Imprimir and two checkboxes for selecting what king of display I want to send to printer.At first time, there are no problems, the printer prints what I want, the form closes and it seems all is allright. The problem is when I try to print again, even the same layout, I call the print form again and I get the error in the picture...Why the same routine executes without problem at first instance and gives this error at second instant?

I need stop printing and paper feeding in the middle of printing in dot matrix printer.(Like a POS Printer - When wrote 'End Doc' on POS printer can stop paper feeding)
View 4 RepliesI am using VB 2008 & Access Databases for creating WinForm Applications. Also i am using Crystal Reports for Report solution. my question is How do i created reports such a way that they can be printed in faster Ascii Format on any DotMatrix printer. The default true type fonts make printing very slower.
I tried to use "Draft 10 cpi" font which come to available me after i installed a correct driver for my Epson printer. which also helped me overcome this problem. however it wont be the scenario with all my clients i.e. they might have different printers having different Make with different drivers installed. i have tried to open such project on there PC but the printing wont come in Draft instead the fonts get expanded too much & the print wont come right.
I basically have an application that generates reports in a .html file, I use a .html file for the ease of making tables and formatting text.Now I would like to introduce a way of printing the reports from my program. Because I use a .html file, the formatting would not the correct if I was to print it directly from my application (as far as I know). For this reason, I would like to print it just like my web browser would have in order to keep the tabular data intact and the text formatting.
View 1 RepliesI'm creating an application which has an scheduler to print and it checks if there is a pending job on the print queue before it prints the next file. I use a timer which checks if there is any file to be printed on my database. Example, the timer ticks and selected 10 files to be printed, it should print the 10 files 1 at a time, if there's no print queue, that's the only time the next file should print. I think another timer is required which will keeps on checking if print queue is done. How will i do this?

When I print the output to a PDF file using PDFCreator, it stacks all of the letters onto each other rather than creating new lines at the places I've specified. I've also tried using vbNewLine instead of vbCrLf, but I haven't had any luck. I searched the web for this but couldn't find anything about it.
i used printForm to print forms, but when i installed the powerpack 3.0 it doesn't work anymore.i am always getting an error "PrintForm is ambiguous in the namespace 'Microsoft.VisualBasic.PowerPacks.Printing'" i am using visual studio 2008 professional edition.
View 3 RepliesI get the error mentioned when printing to a network printer.The error does not occur when run under XP/Win2003, in a WinForm app or when a local printer is used.The error does only occur when run as a Windows Service under Vista/Win7/Win2008 and printing to a network printer.The Windows service runs under a network user that has access to the network printer. Before I print I check if the printername (including network path) is ok by looping through the available printers.
View 1 RepliesI have a new problem with this same Form Printing project and I get exactly the same exception but from the different point of code:
line 538: d.PrintFunction(c, typePrint, mp, x, y, extendedHeight, ScanForChildControls)
The exception type is System.AccessViolationException and it says (after I translate it from my own language in which the message is given in my pc, into English):"Protected memory was tried to be read or written. This often indicates that the other memory is damaged"
I'm a little baffled why I get this error. Scenario: Printing - 6 different things to print including "Permit" and "Permit Copies". "Permit" looks like a drivers license including a photo."Permit Copies" is exactly the same except it has a piece of text at the bottom that says "Sheriffs Copy".
The problem is when trying to print "Permit Copies". Very few of them shows the print preview - most just display the FileNotFoundException error. If "Permit" pulls up the photo just fine, why not "Permit Copies?" It should be trying to pull up the same photo as "Permit" - same file path/name. Where is it wrong in my code?

I'm using Visual Basic 2006 and i am printing with a third party application call NovaPDF. It works very well.NovaPDF works like any printer and i'm having no problem using it. The thing is that i don't want to queue printing document because i need to rename and change their location. Also NovaPDF append to file. So, what i want to do is : Do some kind of loop that the program will loop in until my printer is done printing everything.[code]....
View 3 RepliesI'm not asking for a code or anything, just some info about this.Would it be possible to make a .dot or .doc in word with the layout and such.And then let vb.net read the file and replace some words like <Name>, <Adress>and print the document out with the values name and adress your program sends to the document.
View 4 RepliesI have written a vb.net 2008 Express Edition application that pulls transaction history for customers from an iSeries. Everything appears to work as planned, except when you select to print Datagridview it prints the Date column as a DateTime instead of Date.When you are viewing the Datagridview in the VB.Net application it looks like it should.
On the iSeries the field with the date data is a decimal field with length of 7,0 with the following format CYYMMDD. In the VB.Net application the date portion is correct the time portion always is 12:00:00 AM due to i guess that it is picking up zero's somehow for time. Following is the code for the application.
