View 1 RepliesI'm trying to implement printing functionality into a simple program for my company. It's not necessary, but it would be a nice finishing touch for everyone. And really, in practice, my printing feature works. My problem is that each line is printed on a separate page of paper and I can't find a way to just like, print a page.
It doesn't have to be fancy. I know that I won't need word wrap, nor will anyone ever print more than one page. Here's my ginked & modified code thus far:
Private Sub PrintDocument1_PrintPage(ByVal sender As System.Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
Dim linesPerPage As Single = 0

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.

View 3 RepliesWe have a vb.net application where we have implemented multithreading. We determined that we need to either implement .net remoting or WCF. After researching remoting in .NET on MSDN, Microsoft considers remoting legacy for .NET framework 4.0 and recommends using WCF instead. My question is: can we implement WCF functionality into our VB.NET application or do we need to rewrite the app from the ground up in WCF?

I am implementing a tracing mechanism myself. Now what I'd like to know is what is the best way to implement this mechanism(I mean, the architecture).[code]But then I saw there is an TraceListener class that let's me implement Write and WriteLine methods. The big drawback is that both those methods allow only strings as arguments, and I'd want to be able to send a lot more info than strings. What should I do? Maybe my first ideia is the best?I do know there are a lot of tracing mechanisms like PostSharp and so, I'm just doing this for learning purposes!

In .net (c# or vb) expressions, how would you implement SQL's handy IN() functionality?i.e. value in (1, 2, 4, 7)rather than:
value = 1 or value = 2 or value = 4 or value = 7
There are obviously many ways, I'm looking for the most clean and simple!
What is the best practice for when to implement IDisposable? Is the best rule of thumb to implement it if you have one managed object in the class, or does it depend if the object was created in the class or just passed in? Should I also do it for classes with no managed objects at all?

I am creating a program that will send large files from a server to several clients periodically. I would like to use some sort of Torrent functionality, meaning that I want the clients to sync the information between each other as well as from the server. If client1 downloads part 1, client2 part 2 and so on, I want them to download the rest of the partial files from each other instead of the server. Are there any libraries for .net that can accomplish this? I do NOT want to use a third party tool like uTorrent, but write the actual functionality myself.
