I am using the following code to create a dummy file of a specific size. RemSpace declared as a Long value and is returned in bytes from a separate function in my applciation. I have verified that it returns the correct # in bytes. However, when I execute the following routine, the dummyfile is created, but it never stops the loop. I have to kill it from task manager or it would fill up the HDD. The line:
For i As Integer = 1 To RemSpace
should tell the For loop to stop when it reaches the value of RemSpace, which is a long value in bytes. Here is my complete code.
Public Sub Create_DummyFile()
Dim RandomClass As New Random()
Dim RandomNumber As Integer

I am using a label inside my loop to get a count on the number of records processed by the loop. during testing of the program I noticed that if I load a smaller Table( 1000 records) my label stops refreshing after about 110 and my mouse turns to an hour glass. The program finishes and the label returns the correct count when complete If I load a larger table (10,000 records) it works all the way through???

I've been working on a program that generates a batch file, then when you press a button, it executes that batch file. There are multiple batch files attached to each item in the list box.
[code]...
The only thing that it does when I press the button, is starts the batch file, then goes to function searchtitle, which executes the batch file again when it finds out it didn't work properly.The button text doesn't change, none of the items are being added to my first list box, and I can't do anything to the window after pressing the button. It constantly opens the batch file every 5 seconds or so.
I was in correspondence with someone using my program and he verified that on his system, XP won't shutdown/restart either if my program is running.
Basically what happens is when XP gets to my program in the shutdown process to terminate it, the whole shutdown/restart just stops. I have to exit my program, then start the shutdown again.
The person sent me an image of some threads that were still running after the shutdown process halted and I was curious if anyone might be able to shed some light on this info and what to do about these threads.
These are the threads that are running and what they do: mscoree.dll - a module containing the .NET Framework functions. mscorwks.dll - Microsoft .NET Runtime Common Language Runtime gdiplus.dll - contains libraries for the GDI graphics interface.

I've built a windows form application that steps through a wafer map and sends a command to ink specific dies if the bin number is between certain values. While debugging I have run into an issue with the program crashing with no error message anywhere. While stepping through my code, the place the program stops has occured in two different places but both in the same subroutine in the code I use for the network communications. Below is the subroutine I've seen it break on with the two places it has broke indicated.
Private Sub EventHandler(ByVal Args As EventArgs)
Select Case Args.EventP

I m using access database and vb.net. My problem is that execution of program stops at third and sixth ExecuteNonQuery() methods because they are of string types and i am not able to understand the cause. I have also tried a single insert command but it gives syntax error so I used separate insert commands. The rest of the values are getting inserted properly.
I am constructing a program, i am new to Visual Basic, but i have past programming experience. I was wondering if anyone knew how to form a loop that could...lets say calculate the answer when two numbers are added together,and it would repeat this thousands of times, etc. And if there is a way, would it be possible to calculate the time taken to complete this loop.

View 29 RepliesMakes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

My following code hangs my VB IDE. What could be the reason. I am of the opinion that by 'sleep' I am avoiding a tight loop and so the program should not freeze. What should I do?

I would like to loop over two string arrays but does not work.[code]...
View 4 RepliesI have this function for removing duplicates in arrays[code]...
What is happening at the moment is that the inner loop reaches the array.Remove(inner_element) line for the first time in its second loop during the second loop of the main foreach, reaches the inner next line and then just stops executing. There are no warnings / notices, the debugging step though just ends as if there was no further logic.
I've been having a bit of a problem using the while function.
Here is my code (Simplified):
Dim RandomNumber3 As Random
Dim RandomOutput3 As Integer
[CODE]..............
When running the debug, the program crashes, and when I step into the program, I find that this While statement becomes an infinite loop. This is a program that uses random number generators to assign a value to something, and this while statement is necessary so that there is never two of the same values showing (RandomOutput, RandomOutput2 & RandomOutput) Have to be different to one another.

View 2 RepliesI have 50 checkboxes for 50 american states. The user can choose all 50 or only 1( so basically any number he wants). Based on his choice, I want to insert or update the table in sql server 2008. e.g-
Color = blue and chk1=check, chk2= check and chk3 = check (chk = checkbox). now the user wants to ad 10 more states to this or remove these 3 and add 5 more. so u basically get the idea. the table in database looks like this - ID Color State_id there is a table called states, so stateid shall come from there. so how do i do a loop insert or update in vb.net?

In my MDI Application code I have a form that launches a second form then hides itself until the spawned form closes. It works great unless I choose to close the application while the spawned form is still up.

ChildForm.Show
Me.Hide()

Me.Show() ' error occurs here because my form is already closed by the system. Is there a way to get around this without just an error catcher?

I cant figure why the VB JIT Debugger control transfers the error to the program when I run in Debug mode and goes on in an infinited loop... I am using VB.NET 2008 and MS Access as the database backend.What I am trying to do here is that whenever I catch an exception (I have some C# code dll added to this main program and it should catch the unhandled exception and the addhandler routine will follow suit. So the moment any unhandled exception is caught MyHandler method is invoked and I need to take the backup of the database (Delete if the original file exists, copy the *.bak file as the original file name(was created during new file development) ,name it as *.mdb ) show a customized messagebox warning the user to abort (custom crash dialog instead of the standard default one)Somehow Myhandler goes in an infinite loop stop at line Globals.startBackup inside Private Sub MyHandler..Any idea on this weird AppDomain.Unhandled exception and how to prevent this from happening?
