.net 3.5 - Run 'LoginForm' But Putting Breakpoint But Getting Error IndexOutOfRangeException ?
Jun 9, 2009
Picked up a legacy VB.NET project originally written for version 1.1 of the .NET framework. I'm running Vista with .NET 3.5. I have cleared out all the original error and the project will build; it just wont run.
As far as I can tell, it is trying to run 'LoginForm' but putting breakpoints in doesn't work because the error is thrown before the breakpoints are reached, regardless of where in the file they are placed.

I have a solution with number of projects developed in Visual Studio 2005 and the breakpoint is not working displaying message 'the breakpoint will not be currently hit' No symbols have been loaded for this document. I have tried solutions/suggestions in the forum and none is working. I have deleted the obj and bin directories and nothing worked. Selecting the Debug Menu, Windows, Modules option I can only see the pdb files for some projects (dlls) and cannot see for the project I'm debugging.

I was testing out an application that I created which then I recieved an error as said in this topic title. The application that I am making is one where it requires 2 form GUIs, my main one is called frmConferenceRegistrationSystem (the first picture) and my secondary one is called frmConferenceOptions (The second picture) and what they are supposed to do overall is total up the cost of registering for a conference that is selected in frmConferenceOptions and the error that I am recieving is within the ElseIf statements in the frmConferenceOptions form (third picture and first section of code) And also here is the rest of my code for both of my form GUIs at the bottom of this topic
If ltbList.SelectedItem(IntrotoECommerce) And ckbConferenceRegistration896.CheckState = CheckState.Checked Then
My frmConferenceRegistrationSystem Code:

I am working with a listbox that contains reportnames. Some reports will have parameters, some will not. This application lets users view and run SSRS reports. It also allows them to send email messages to one or more recipients with a web link to the SSRS report using Report Viewer. What I have done with the listbox is whenever a report that has parameters associated with it, the control (DateTimePicker) appears on the screen for the user to pick a date. When a report with no parameters is selected, it simply changes the Visible property of the DateTimePicker to false so the user won't have to use it. Everything works fine, I am able to pick a report with parameters passed as part of the link that gets sent via email to user. User clicks on it and report gets displayed with the correct parameters in the ReportViewer. However when I exit out, I get this IndexOutOfRangeException exception. Here is my code for listbox -
Private Sub lstBxReportName_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstBxReportName.SelectedIndexChanged
Dim y As Integer
[code]....
When I debug, error is on second Dim statement for rowViewReportNameChange. I guess I can simply include the Dim statements as part of my Try block and I can catch the exception?

My ConnectionString is working fine.
I've saved my SQL command in a string as follows: Dim sqlcmd As String = "select LEFT(eventDate,10) from Locations"
Dim sqlreader As SqlDataReader
Then I open my connection and at that point everything is fine.
I can execute the query just fine but the error comes up when I try to fill data into my webapp.
sqlreader.Read()
loc1Date.Text = sqlreader("eventDate").ToString() ---------- This is the line that is giving me the error "System.IndexOutOfRangeException: eventDate"
I just want the date pulled and not the time. get this date to fill into my textbox on my webapp.

Currently, I have a LoginForm that authenticates a user and it works fine. I have a MainForm, which is displayed if a valid username and password is entered. I have done this by using the following code in my LoginForm:Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles
[Code]...
Now this does exactly what I want except I fear it's a work around and it's not the best approach. Also, note that I am using Me.Hide() to hide the LoginForm, is there a way to show the MainForm and then close the LoginForm instead of hiding it? Doesn't Me.Hide() call creates an overhead?

I have 2 forms, main Form1 and a loginform. When I start the application, first "Form1" is loaded and then with a button click, user can load "loginform" if required to enable/disable some features/controls on Form1.The sequence is like this:
1) Load main form Form1
2) click a button on Form1
3) Load the loginform.
4) enter user/pwd and click OK button
5) enable/disable "GroupBox" control on Form1 if login sucessful.
For this,I made a click event for OK button in loginform, so once user clicks the OK button, I want to call one function which is defined in Form1 as a Public, which enables/disables the "GroupBox" control on Form1. The code structure is like this:in main Form1, i created a function like this:
Class Form1()
Public Function DoThis() ' Function to enable/disable GroupBox control
....some task...
[code]....
I am not able to call the DoThis() function in loginform. Please suggest me with a piece of code how to do this?? remember that Form1 is my main form which is loading first.

Basically, what this code is supposed to do is compare the text inputted in the input textbox with the text of the string answerstring. It seems to successfully compare the two, but every time I type the first char into the input textbox the program crashes, givingmythe Out of Range Exception. I assume it means the Char() "array" thats built into vb is out of bounds, however as i've set the while loop so that it only is executed when the whilecount is less than both the length of the input textbox and the answerstring, I don't see how it could be out of bounds.

The weird thing about this, is that when I first run it, I was able to Bind it to all the Textbox and thought everything went smoothly, but when I run it again without any changes in that code, that error suddenly appears... sometimes that error went to other dr.item(""

I have breakpoints set in my code, but when the app loads, a little exclamation point shows up that says "The Breakpoint will not be currently hit. No Symbols have been loaded.
I have searched the forums for possible solutions. I've tried deleting the bin and obj folders and rebuilding my project and that did not work. I've also verified that the build configuration was set to debug and not release, which was also true.

I have a problem where I can't get VS to stop at a breakpoint. It is a DLL that will be used by a third party exe (Intuitive's ERP). Another developer gets his machine to stop at a breakpoint. Mine won't (it always goes to the dll) and I opened the same project on my machine. I tried running the gacutil with the -u option but it says that no assemblies match. This is going to really slow the development process if I have to debug via messages boxes and files.

I've been trying to build this application with vb .net 2005 for the last couple of weeks in a computer programming class. The purpose of the program is to parse data from an html table displayed in the webbrowser and display it in a datagridview format (I plan on expanding it later). I've coded pretty much everything, but I keep getting an error related to the arrays that neither I nor my teacher can figure out. I attached a zip file of the complete project, in case anybody who was willing to look at it needed the rest of the program. I also included an "Items.htm" file with a html table in case people wanted to test running the program.
Public Class tableForm
Private tfColumnInteger, tfRowInteger As Integer
Private DataSet As DataSet = New DataSet("HTML Parser")
Private Table As DataTable = DataSet.Tables.Add("Table")

I have a situation where I have a databound datagridview and if you try to scroll to the bottom about half way there it generates a System.IndexOutOfRangeException. However if you click on one of the header columns, causing a sort to occur, before you try to scroll all is well. Any ideas as to why I can only scroll my datagridview after it has been sorted and not before? Interesting enough if I click 'OK' it just re-generates the error. This occurs several times over and I can see the rows in the datagridview being blanked out one by one with each click of 'OK' until all visible rows are gone and then...poof...all seems fine again and I can scroll and click like normal.The first screen shot is of the initial error dialog. The second is a shot of what is happening to my datagridview as I click through the series of resulting error dialog boxes.

i have just started learning vb and am enjoying it but am having problems. i want to design a three-way dictionary that allows a user to type in a word (English, Kazakh, or Russian) and have that word translated into the other two languages. The user can also add his/her own words and translations to the dictionary.My dictionary is called: "dictionarykre" and is formatted as follows: engword=kazword=rusword. i am reading the dictionary line by line and parsing it with "=", then putting the words into arrays.i keep getting the following error intermittently: IndexOutofRangeException was unhandled. Index was outside the bounds of the array. The error throws on the "KazListBox.Items.Add(arraytextfile(1))" line.i change the dictionary and the program will work for awhile, then the error will occur again.
