Aug 6, 2011I am trying to fill an array of buttons:
Public buttons(0 To 30) As Button
This is how I am currently filling it.

View 1 RepliesFilling Array From Largest To Smallest Index
Dec 10, 2009What I am trying to do is fill an array from the largest index to the smallest index -- with the desired effect of reversing the values in the array. I have been looking at doing it with 2 for...next loops and I thought I had it, but I don't. As the reversed array is empty at the end of the 2 for...next loops here is code that I have been playing around with.

Set Array Bounds And Filling With Random Numbers?
Apr 1, 2011I want to set an array upperbound limit to 50. I need a loop to create a random number and place it in the array until it reaches 50( I've set up the random generation part). My question is do I set the upperbound limit when I create the array and redim for each sample being added or set the limit somewhere else? I understand how to set up a basic array and how to redim arrays, but adding the loop to it is confusing me.[code]...

Array Is Not Filling Values From The Loop In Visual Studio 2010
Jun 10, 2010I am making my first windows forms application in VS2010 and I am having trouble with arrays. I have code that dim's an array 'TabSiteInfo(2,20)' as a string. Then, I have a Loop that adds records to the array. The problem is that my array is not filling values from the loop. I know VS2010 handles arrays differently, but I have this same code working fine for me in VS2008 ASP.NET application. Below is a sample of the code.

VS 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?

Sep 15, 2011I tried the code below but unfortunately, all i get is a combobox with U,s,e,r,s, as each line in the items collection and not the filenames of the relevant files.
the DirGetPath("Users") Function below returns my default document and application paths and appends "Users" to the end as the relevant files are stored in that Folder.
All I get is a combo box with the items as U, s,e,r,s (i.e. Users spelled out).
I tried all of the following as alternative methods too:

C++ DLL In VB Crashing
Dec 9, 2011I have a dll that someone made me in C++. I needed to use this dll in VB, in order to do that I had to make another dll in C++ that has functions I can call in VB.
The C++ dll I made has 4 functions. 2 callback functions that retrieve information from the original C++. And 2 functions that I can call from VB to send that information.
I know the original dll works fine as Ive tested it endlessly in a console app.
However when I use it with my dll and VB.. I get random crashes.
There is almost no code in my VB app as its just for testing. It just outputs the information so theres no problem there.
I believe the problem is in the C++ dll I made. I am pretty new with C++.I think maybe a variable gets accessed in 2spots at the same time (is this possible?) and causes it to crash?[code]...

View 2 RepliesBonjour .Net App Crashing Due To Svchost.exe?
Aug 5, 2011I developed a .net application which uses bonjour to chat with other instances of the app on LAN. The application works fine on 5 pcs(4 with xp sp3 and 1 with windows 7) out of 6. On one computer (with windows 7 installed) the app crashes as soon as i try to register into bonjour service.
After digging deep into the problem i noticed that too many svchost.exe processes are running on the pc on which app crashes. After carefully terminating the svchost.exe's i came to know that by terminating one svchost.exe which consumes around 50Mb Ram, the app works absolutely fine.
The process path "C:\Windows\System32\svchost.exe"
Process Command Line "C:\Windows\System32\svchost.exe -k LocalSystemNetworkRestricted"
When i terminate the process, app starts working fine.
PS : Even after terminating the process restarts itself and app works fine.

Combo Box Crashing Form?
Jun 1, 2009but it's strange. I have a few combo boxes on a form that are fed via select query. They each are populated by their own table. Each of the tables feeding them have a codeassociated with a name, function etc... the code is what is stored in the form's table. I have another select query that converts the code to the name or whatever so that the user does not see the code, but the name associated with it when the form loads.What is happening is: The form loads and if i don't touch any of these combo boxes every thing is fine if i update them, I can't tab off the combo box or move the cursor anywhere, or even close the form. I have one of these boxes with the same code and it works fine.. I don't understand what is going on... I have an after update function that is the same on all of them and it is indeed updating correctly....

No Errors But Program Crashing?
May 11, 2012for our culminating activity we must make a program that uses a bunch of things etc.
i decided to go the extra mile and make sudoku.
The problem lies in generating the puzzle, the program always crashes, but there is never an error. im sure there are easy ways to make the generator, but from what we've learned this is the only way i know how to do it.
Private Sub FirstBlock()
Randomize()
intNumber(0, 0) = Int(9 * Rnd() + 1)
[Code]....
i made a function for each 3x3 square, and what happens is the block its currently on, checks for interferences horizontally, vertically, and within each 3x3 square, because computers process in order, i set it so that it only checks for previous block interferences, since this is the first 3x3 quadrant, there are no previous horizontal/verticals to check.
The code works fine, the problem is when i run it, it says its running but no form appears, i learned to use a progressbar to try and separate each 3x3 block to generate individually, to try and split the processes up 1 second at a time. the problem is, it does run, but it only generates a certain amount before it crashes, and every time its different, sometimes it generates half the puzzle, sometimes 1/3rd, sometimes only the first quadrant.
Program Crashing Using Treeview?
Feb 20, 2011In a program I have written I have FileSystemWatcher pointed two directories. When there is a change it keys up and using a listbox rewrites the files in the folder to the listbox. This all works just dandy.. however..
I wanted to change the listbox out for a TreeView. When I first initialize the TreeView on program start, no problems, but when the FileSystemWatcher kicks in the program crashes. I have tried running the debug but it crashes without any error, just the windows error that the program has stopped working.
I am running Dual XEON Quads with 8Gb RAM and Win7 Pro up to date on all patches so there shouldn't be a problem there.
Here is the code for the listbox:

Program 2010 Constantly Crashing
Jan 12, 2012This is an annoying issue that started less than a week ago and couldn't come at a worse time, as I have a major project deadline to meet. At least once every TEN minutes, the program crashes with the error "Microsoft Visual Studio has stopped working" -- it only occurs when I am writing/editing code while execution is paused (Edit and Continue), which I do all the time since I am stepping through rather complex subroutines line-by-line. I literally have trained myself to save after each line of code I write, delete, or change, so thankfully I never lose much, if anything, when I restart, but it is irritating and time-consuming having to set up everything in the program and get to the place in the code that I was before. I have installed VS 2010 SP1, tried deleting the .suo file, and a few other supposed fixes that I came across online, to no avail.[code]...
