Some of you might remember that my application got data from a PLC which is a Short. That is converted into his base 2 equivelant and turned into a boolean array.Problem is, this 16 bit word i'm getting is little endian (right to left) and I want to turn it into a big endian (left to right).

That doesn't make sense to me: I just have to declare an instance of the BooleanSwicth to be able to manage (disable) tracing via the .config file? Should I like ... use ... the object somewhere?

View 1 RepliesMy coworker's installation of visual studio 2008 breaks every time there's an exception, mine doesn't.
We've been looking for how to stop his from doing this but haven't had any luck. The only difference is that mine was initialized for C# while his was initialized for VB.

I am supposed to be writing a program for my instructor using VB 2008. It is sort of like a quiz program. You build the "light bulb" program but instead of names and colors, it consists of two forms. Question 1 with a "next" button and the second form for Question 2 with a "previous" button. I have no idea how to link the two so that when you click "next" it goes to the second page and vice versa.

I am creating pivot tables in VB.NET and have run into a problem I did not think would be as difficult as it is turning out. When I create a pivot table it adds in subtotals for each row and I do not want that. In excel you just drag down the subtotals option and tell it to not display subtotals. I looked into the VBA for it and it is several lines long of this format:
ActiveSheet.PivotTables("Main Highway Pivot").PivotFields("Division"). _
Subtotals = Array(False, False, False, False, False, False, False, False, False, False, _

I'm trying to build an application to increase my understanding of visual basic. I may have set the bar too high for myself but it's the challenge that makes it fun right? Anyway, I'm trying to make a transition effect of a page turning. The application is a brewing database which looks like a book. I think the transition would make it look more professional. Dose anyone have on how I might be able to accomplish this? A basic example even would go a very long way.

View 10 RepliesA week or so ago, you folks really taught me how to use the KeyData event. I adopted some of the coding to make my new code so much better. A few days ago, I thought I figured out how to run my little game. You see, you have two buttons. Comment and Uncomment. You Press Control + K and then after that, you press Control + (C or U) to activate the buttons. And I thought it worked! But my buddy figured out how to break it! The thing is, I need to figure out a way to make IsCtrlK (Look below) False if any key that isn't Control + C or U is pressed right after it. What would you suggest I look into using?

Late binding is not allowed and that's how we want it. Depending on whether our program is running on a LAN or the Internet, we need to dim an object as one of two types. We use an if...then statement to ascertain whether or not we are running on a LAN or the Internet.
When we declare our object inside the if...then statement, we have declared in the wrong scope and cannot use the object. When we declare it as an 'Object' type and use DirectCast inside an if...then statement, we receive a late binding error. How can we get around this problem without turning off Option Strict?
I have two DataGridView controls on different forms. One is bound and one is non-bound. I am not sure if it is my imagination but I find that properties behave different based on the bound or non-bound. When I compare the properties I do not see any that are different except the data binding properties. On the non-bound DataGridView, the whole line is always highlited, I cannot figure out how to turn it off. Trying to make the grid behave more like an excel grid.

View 3 RepliesI 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

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?
