Using Access 2003 and VB code, I have created a form with a number of labels. The labels will display an employee's names. I have named the labels name1, name2, name3...etc. Using an ADO data set and DCount I have determined the number of names in an Access table (the number of names can vary). What I want to do is for each record in succession to pick the first name and surname from the data set , combine them into a full name (this part has been successful), and then set the full name into the label caption in succession. Example: full name 1 into name1, full name 2 into name2, full name 3 into name3... until all names appear as labels on the form.
I created a counter to and a variable to increment the label number but when I address the caption property of the variable containing the new label (e.g. name1, name2..etc.) it throws an errer at runtime. Here is the code:

My day job is mainly coding in vb.net, so I am very familiar with it. While doing my first few dozen project euler problems, I used vb.net just to get the hang of the problem styles. Now I'd like to use project euler to help me learn a new language and have been running a couple in python. However. I've hit a snag.The following code will print the largest prime factor of a given number:[code]However, the factor never ends up printing. Am I missing a nuance of python?
View 1 RepliesI wrote this application in VB2008 and it ran for three years without problems(It had one first chance error during that time but ran correctly). I started having problems at the first of this year with a textbox not showing the update for the date code correctly. So I thought that maybe some update to the system had changed and I might need to do some code changes to take into account for these updates.I first tried to convert it to 2010 but the conversion would not operate correctly even though the code showed to be correct.It would jump from one form to another in the middle of a if statement using debug to step through the code. the if statement would just test for a variable to be less than 2 and then be changing the text in a textbox. So I decided that It would take longer to correct the converted application then to just use VB2008.
So I went back to VB2008 and my XP to find out why the date code had quit working. This code had been working correctly for three years.I was thinking some of the code used had become outdated in some way, because a copy of the original source would not run in debug mode correctly. It showed the same problem of not updating the textbox. I stepped through debug and found that it was doing the same thing as the VB2010 version and jumping in the middle of the if statment. So I rewrote the code and used the format string command to build the date code in stead of the seerating out the date into 3 variables using a split statment.This works for the textbox problem and stoped the jumping to a different form. But since I have went back to the original code I have the first chance errors comming up.
I have several first chance exceptions being thrown from debug. This happens when I fisrt start the debug and I have put break points all through the applicatins to try and find the problem I have also enabled debug exceptions Common runtime thrown and it still gives the exceptions but no break point.I have option Strict on. There is no errors or warnings showing after a build. I have cleaned the solution and exausted all my methods of troubleshoooting this problem.The following is what I am recieving while in debug mode in the immediate window.
A first chance exception of type 'System.IndexOutOfRangeException' occurred in LABEL MAKER 2 Forms.exe
A first chance exception of type 'System.IndexOutOfRangeException' occurred in LABEL MAKER 2 Forms.exe
A first chance exception of type 'System.IndexOutOfRangeException' occurred in LABEL MAKER 2 Forms.exe
A first chance exception of type 'System.IndexOutOfRangeException' occurred in LABEL MAKER 2 Forms.exe
A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll
A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll
Now if I run this as a published application I get the same error as the first one on the above list and it gives a error window with continue, exit,and details, if continue is pressed it will allow me to continue and the application runs correctly.The details just say basicly the same as the error with no error number and that the error was in my application.exe. Nethier of these errors will give a break point so that I can find the problem. The problem does not appear to be in my code because this happens before the first form appears.

I'm trying to use this overload
Split(ParamArray separator() As Char, count As Integer) As String()
However, when I use this
Dim tokens() As String = e.Node.Text.Split(New Char() {":"c}, 2)
I'm getting the ArgumentException (Illegal enum value: 2)
I tried using named arguments with no effect:
Dim tokens() As String = e.Node.Text.Split(New Char() {":"c}, count:=2)
Using this overload didn't weed out the error either:
Dim tokens() As String = e.Node.Text.Split(New Char() {":"c}, count:=2, options:=StringSplitOptions.None)
The error is occuring only at run-time. Intellisense swallows it without problem.
We have a VB 2008 Windows application that is deployed on several hundred computers. For some strange reason only 2 computers out of the hundreds are experiencing the "Error creating Window handle" error. It is happening more consistantly on one machine than the other. Any idea what might be causing annoying error on such a limited basis? (It's a Windows XP machine that it is happening on. That's all the info I know regarding the machine currently.)

I have a problem where a form is closing when it shouldn't be. I just don't see why this is happening so I hope someone can see the obvious error that I'm missing.The user is on a form called frmPersonalAddress. If he clicks on a button labled "Add Children", he will open a new form, using the .showdialogue method called frmChildren.FrmChildren contains several text fields that may be filled and a single CLOSE button. When closing, the program will examine the fields. If it finds an error, a Messagebox will display with the error and the form should remain open. If there are no errors, the form will close

Last night my project worked just fine. I left my system up overnight and came in this morning - my project is still on the screen, so there was no update/reboot or any of that. I added 6 lines of code, and suddenly get Build Failed. I removed those lines of code, and still get Build Failed. I restarted Visual Studio, and still get Build Failed. No Exception is ever thrown and no cause for a failed build is ever given. Output is set to Diagnostic, and it indicates nothing wrong or out of the ordinary - every task completes successfully right up to the end when it says Build Failed.
View 6 RepliesMy program has two lists, one a listbox and the other a listview viewed in details mode.
Both of them change heights (get taller) for no obvious reason. I am having to add a call to a method that resizes them to the end of every method, which is kind of absurd, I think. Also, when the window size is changed, these components change size, which means I have to keep track of that.
Edit: I had also thought of adding a timer to handle this.

View 2 RepliesIs there any way I can find the exact reason a form is closing ? To be more specific , I'd like to find when a form is closing :1) because the user pressed the X button on the upper right corner2) due to code (Me.Close , MyForm.Close etc)I know I can use the FormClosing event and use this code :If e.CloseReason = CloseReason.UserClosing Thenhowever it seems that the CloseReason.UserClosing catches both cases (closed by te X button or by code) . So , is there any way I can find exactly the reason a form is closing ?Back in VB6 , the correspondent UnloadMode variable of the Form_Unload event could be "vbFormCode" which indicated specifically that the form was closed by code
