VS 2008 Small App To List And Add Printers?
Oct 9, 2009Am looking at making a small application that will list printers on two file servers at two separate sites, from this app they can add the printer/s to there local computer.
I have found a small application on the web but there are a few improvements it could do with.
They are; Show all local printers without having to click on a check box. Show sites printers without having to click on a check box. Show comments about the printer�s location other then just the site.
If it is possible I would like to update this one, but if there are any other examples where I could download something similar, or even some help with how to begin to create a new application.
Here are some screen shots, of the application form and the xml which holds the folder structure for the sites.

VS 2008 Converting Bitmap To String?
Feb 23, 2010I have made an application with a client, server and listener. The server is a console app and the other two are Windows Forms Applications.
Basically i am using a Network Stream to send messages from the client which go through the network to the server which bounces them to the listener which then reads the message and tells the app what to do. (For example if i sent "shutdown", the listener would read it and then execute "shell(shutdown -s)".
The messages are sent like the following SendMessage("shutdown") but when i use a screen capturing API and send from the listener to the client like so SendMessage(background) i get the following error:

View 7 RepliesVS 2008 Filling Array With Pixel Data And Turning It Into A Bitmap?
Jul 22, 2009I have a small 10px by 10px image, and I want to use VB.NET to find out if that image is (an exact) part of a larger image.I thought a method of doing this would be to lock the bits of the larger image into memory and then loop through each pixel in the image and for each pixel, I could take the 10px by 10px section which is down and to the right of that pixel.. and then compare it to my smaller image.
This is the code I have so far:
'Lockbits of larger image to memory
Dim bmp As New Bitmap(Image.FromFile(System.AppDomain.CurrentDomain.BaseDirectory() & "picture.bmp"))
Dim pxF As PixelFormat = PixelFormat.Format24bppRgb
[code]....
when I'm looping through the 10 by 10 section and I find the R G B bytes for each pixel, how do I store this in my rawImage array so I can convert it to a back bitmap and compare it with my original small 10by10 image?
