I have VS 2008 and use VB, not C#/C++ or whatever else. I'm trying to make a battleship game, and I've decided to use the only method I can think of to control the grid. A 2D boolean array for position marking. I have the array set up, and the grid set up in the design form, but I can't figure out with all my research how to link them together. I'm writing this program to shake off the rust before school starts again, and for fun. I took VB in school last year, a half year class, so I have a foundation, now I'm self-educating myself above and beyond the class. I've searched for a way to use a picture box array to use the coordinates of the ship to .Visible=True the picture boxes. I've been working on this for 2 days straight with no results. I just need a little nudge in the right direction. The exception I've been getting with my latest concoction of code is NullReferenceException was Unhandled. I think its referring to the fact that I have no idea how to link the picture boxes into the array. Here's my code, and I'll comment where the exception is thrown:
Private Sub cmdStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdStart.Click 'label for GoTo statements is Tryline:
I have this code in my system which I use to retrieving images from a database by formatted blob. But some database records don't have pictures ([BLOB - 0 B]). list code for me to place an error picture in picture box1 when a picture is not available.
Dim bytes() as byte bytes = (objdr("picture")) Dim memStream as New MemoryStream(bytes) PictureBox1.image = Drawing.Image.FromStream(memStream)

I know how to find the mouse coordinates of different controls and such. What I need is slightly unique.I'm needing to find the coordinates of a picture within a picture. So if I had a picture of a black box with a red x in it, I would need to find the red x inside of it.I already have the bitmaps of the images, so I only need to know how to find the coordinates of where the images lie inside one another.
i have this problem i would want to solve urgently...when i import a picture into my picture box in vb.net using this code

My plan is to use a database to hold her recipes and create a user interface with search controls and different stuff, this way she will be able to add new recipe's and the program will have a much more modern feel to it.
My question is, I have added a picture box control to the new recipe form and when I click on the picture box I want the program to load "my pictures" and let me select a picture to load into the picture box, like you can on ebay when you are selling stuff, you can select your picture and it loads into the picture box.
As far as starting this off, I can add a double click event on the picture box control, this will trigger whatever code I need to use to load the open file dialog.
Can I use simaler code that I used for a text editor program I wrote for opening saved documents?
I'm a programming enthusiast, and recently I am making a program that communicates with a webcam and captures an image. I copied the API call for avicap32.dll from some website and the program works just fine.

I have some operations of Picture Boxes etc being performed. After the user finishes with the formatting, I want to give the user an option to print the work.But its the work is not done on the Rich Text Box but on picture boxes. I am not even sure, how many of the picture boxes would be there after the user finishes the job, since I have provided option for dynamically creating picture boxes as well.
I have a few problems i need to solve. Firstly, I am looking for a piece of code i can use to display a picture from a bank of pictures. It will work on the basis of generating a random number and loading a picture that corresponds to that number.
i.e. Dim RandNumber As Integer Dim RandClass As New Random RandNumber = RandClass.next(1, 10) If RandNumber = 1 Then Picturebox1.image = picture1
Secondly, can I then use subsequent picture boxes to display pictures from the same bank of images, without displaying the same image? Finally, I then need to be able to click the picture or a button beneath the picture to select it as an answer to a question and then the whole process starts again.
how to copy the left half of an image, in my case its the let half of a .jpg of a whale, and "paste" it over the right half of the image. Any help would be great, here is some code that might have something to do with it, i would prefer that i could get an answer that accomplishes this by modifying this code but if not that's cool. picture should go from looking like  to [[
Dim mb, rb As Bitmap Dim x, y As Integer Dim r, g, b As Integer

I have a picture box (say, 300 x 400 pixels) and I ask the user to load an image file into it. Well, I can't figure out how to make the control "squeeze" the picture in the picture box to make it the same size (or just "shrink" the picture to fit).
I tried all variations of the property "BackgroundImageLayout" (zoom, center, tile, stretch) and none of them are doing what I'm looking for.
