I've used this example to create a paint application in vb express 2008, however the example can only open and save .pic files! How can I make it so that my application can open and save a commonly used image type, such as bmp, jpeg or png? I would imagine it can't be that hard, just saving what has been drawn in the picturebox into an image file, or loading an image into the picturebox.
I have tried to make a load event by using some simple code I've made:
If OpenFileDialog1.ShowDialog() = DialogResult.OK Then
PictureBox1.Image = Image.FromFile(OpenFileDialog1.FileName)
If Not (PictureBox1.Image Is Nothing) Then
m_Picture = Nothing
PictureBox1.Invalidate()
[Code] .....
When I simply delete this section of code, pictures open fine however of course then I cannot draw, which defeats the purpose of my application. So how can I open and save images with my paint app?

I am currently working on a small drawing application and I wanted to know if it was possible to insert a paint application inside a form,like vertically dividing the form into two. On one side you have some literature and on the other side you have the application.This paint application just mimics the same Microsoft paint whereby you have an open and save option

I found some code online for a vb paint application and I modified it for my use, which is a signature application. It uses a tablet connected to the pc to write the signature on the screen and then save it as a bitmap for later retrieval.The only issue i am having right now is that if you write on the tablet too fast, the signature gets broken up alot, any way to quicken the paint process in the code so that I can get a smoother signature?
Here is my code:
Imports System
Imports System.Collections
Imports System.Data
Imports System.IO
Imports System.Xml.Serialization

I have a number of programs written in VB.NET 2010 that load and run on every computer I've tried them on. This week I replaced my mother board with an IBM mother board using a Pentium 4 running Windows XP Pro. I install the programs but as soon as they start to run, they immediately shut down. If I run them in Visual Studio 2010, they run fine.

What I want it to do is, as I'm typing the word, that it highlights it on the board using the button(x,y).doclick sub which highlights it. Right now my implementation finds the first letter, then keeps trying each letter until it meets the 8 corner condition (ie it is neighbored to the last one) but this does not always work. If there are say 2 "G"'s on the board and I want the bottom one, this will not work. Can somebody give me an example of psuedocode

We learned How to assemble an input/output control board that would connect to your serial port. We were able to use out statements (back in the old gwbasic) to send output signals to the parallel port to turn on/off different outputs. The board had connections where you could connect lights, relays, etc, and had connections where you could attach switches and sensors.
I have been looking for something simple that I can manipulate in my programs. I already have an ActiveHome X10 interface which includes an activex for receiving and sending x10 signals (home automation, turning lights on/off, etc.). I want something that I can straight out connect relays to, and sensors as well. I don't want something that connects to the serial port since that is already being used up, the parallel port would work fine, or even better usb.

I am making a variation of the board game Trivial Pursuit. I am having trouble moving my piece around the board. The board is a circle divided into 32 squares, that are coloured. I am wondering how to get the players pawn to move around the board if it is a circle. They have to move according the the number they role on the dice. I have the dice rolling and finding numbers, but its the moving i'm having trouble with

I'm currently developing a chess program. In my program, the problem I'm currently having is the slow drawing of the initial board. Here's part of my _gameGraph.DrawImage(MyResources.Marble_White, New Rectangle(x, y, 70, 70)) The code here draws the black & white squares using a for/next loop. I later use another for/next loop on the array holding the piece values, which uses the same type of function to draw the pieces on top of the squares. Both the pieces and the squares are .PNG images.

I am trying to control the security board using the Windows Firewall which connects to my server that was made in VB.Net. My only problem is when I open the Windows Firewall my server crashes. It also displays this error: "Error, win%fir%90y4e does not support this server. upgrade you version of Winsock.". So I upgraded myself to the latest Winsock that there is out there. After doing so I try again and my server still crashes, but this time with a different error. The error this time was the following: "Error, no client is available for win%fir%90y4e. try again later.". What do I do?

I'm in the process of making board game created into a pc game. It will be a 2-d basic board game. What I'm looking for, how to move pixels a certain space. I'm not all certain on how the game is played but right now I'm just wondering how to move a picture certain number of spaces. This will most likely be based on a dice roll I'll create later.
