Array - When Reaches Line 17 - Skips The Whole Sub And Then Next Breakpoint Is Unable To Be Found
Jun 3, 2011
I'm attempting to run my first program in vb.net and everything works BUT the array.
Here is the archive: [URL]
The problem occurs in the Maps.vb file on line 17 when the assignment of variables to the array starts. When running the breakpoint debugger you will notice that when it reaches line 17 it just skips the whole sub and then the next breakpoint is unable to be found.

My program plays sort of like a novel, where I add paragraphs to a multiline label whenever the user presses the enter key. Eventually the label fills with text so I have to clear the label to continue writing.What I need is a way to find how many lines of text are in my label, so after it passes line #50 I can make the label automatically clear itself and begin writing on line #1 again (as if the user just flipped to the next page of a book).My first idea was to turn AutoSize on and monitor the height of the auto-sized label box. After it passed a certain height I could clear it - but this didn't work because I need the label to be of a certain width.

Using VS 2010 Pro SP1 - XP Pro SP3 I set a breakpoint with F9 and the line turns Red. When I press F5 to start debugging, the Red Breakpoint jumps to another line a few lines away.

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 just had to do a complete reinstall of my development machine (reinstalling VS 2005 & SQL Server 2005). I finally am able to run my projects in VS. I can set breakpoints, however, when I come upon a breakpoint, the IDE won't let me "step" thru each line of code. What am I missing?

Once it is found, I want to return the line number it was found on.
Also, I would like to know how to delete all blank lines from a TextBox.

Here is the code:

I would like to know how I can read the file line by line and then add all results into an array list.

I am trying to search an array and then say whether the result was found or not.
So far i have:
Option Explicit On
Module Module1
Const MaxAnimals = 20
[Code]....
Now i have looked online and all of them seem to give you like ready made things on VB but i have not used them yet and i know there is an easy way of doing it as my friend managed to do it before but i can't get hold of him.
Basically it is a program (There is more of it but this is not necessary for this) which puts the names of animals into an array then you can either add another animal, or in the sub i am doing at the moment view all the animals in the array but i can't work out how!

I have used StreamReader to read the contents of a file to its end, and parsed each line into an array entry for an array of strings. That part works, and I have verified that each array entry does contain the proper line entry from the file. However, if I were to go and print out (say, in a MsgBox) each line, every line after the first one would look like (Carriage Return)(proper thing), yet searching for the CRs using InStr yields that there is no CR or ControlChars.NewLine etc. character in the string. I'll show you my code:
Dim FileParse(255) as string
Public Function FileRead(ByVal FILENAME As String)
Dim sr As New System.IO.StreamReader(System.AppDomain.CurrentDomain.BaseDirectory & FILENAME)
Dim FileData As String = sr.ReadToEnd
[code]....
I just set the For Loop from 0 to 10 because I am unsure how to tell the loop to end when it has finished with the last entry of the Lines() array, and since the program will later be writing to the source file, it is likely that the number of lines will change (which is why I just arbitrarily set the FileParse array to have 256 spots).

I have following code somewhere in my VB.NET 2008 program to create an array of files found in a folder:
Dim objFolder As New IO.DirectoryInfo(strXMLImportPath)
Dim arrXMLFiles2Import As IO.FileInfo() = objFolder.GetFiles("*.xml")
...
UpdateFileQ(arrXMLFiles2Import)
[Code] .....
When setting "option strict" to on, I'm getting following error on the line:
lbFileQ.Items.AddRange(dirlist)
Overload resolution failed because no accessible 'AddRange' can be called with these arguments:
'Public Sub AddRange(items() As Object)': Option Strict On disallows implicit conversions from 'System.Array' to '1-dimensional array of Object'.
'Public Sub AddRange(value As System.Windows.Forms.ListBox.ObjectCollection)': Value of type 'System.Array' cannot be converted to 'System.Windows.Forms.ListBox.ObjectCollection'.
Although everything works fine with option strict set to off, I'd like to correct this problem. Also note that array "arrXMLFiles2Import" is used later on in the program, so I can't change anything on that.

I am trying to check the value of a field before decided what to input into a drop down list in ASP.net.
I am using datareader.Read() in order to read the recordset so I can do this. However this then skips the first row of data . . The drop down box is basically a list of sizes and colours . . . So currently I am missing the first size.
Here is the code:
Using cmd As New SqlCommand("doGetAllSizesForProduct", oConn)
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.AddWithValue("@id", CType(Request.QueryString("id"), Integer))

Setting a breakpoint on anything afterwards doesn't work and it doesn't break.I tried catching exception but none are occurring, so I'm not sure what the problem is.

I have a binding source that when I use the MoveNext or MovePrevious methods it skips records. I've tried circumventing this by using Position ++ and Position -1 instead but I still get the same result. I even resorted to manually sorting the binding source to see if that would help but no joy as well there.
I have a bindingsource that is tied to a dataset class. I added 2 records to start and movenext worked as it should (moved 1 to 2) as well as move previous. I added a third record and now the movenext method skips record 2 and moves straight to 3. The same symptom also occurred for move previous. I also added a fourth record and it got even weirder. As before when movenext was invoked, the record pointer moved from record 1 to 3. I invoke MoveNext again and it moves to record 4. Now I hit MovePrevious from Record 4 and it moves to record 2 skipping record three.
Others who are working on forms with different bindingsources ties to the same dataset class are seeing similar things.

I'm trying to detect when the tab key was pressed and intercept it in certain cases. Since the form I'm working with has many fields, I've tried overriding ProcessTabKey so that I don't have a separate sub for each control. However, I've found that after adding a simple ProcessTabKey method, each time I press tab it skips one of the combo boxes. In order to duplicate the situation, using Visual Basic Express 2008, create a new Windows Forms project and add 5 combo boxes to the form - allowing each to automatically get an incrementing TabIndex.
Then add the following code the form:
Public Class Form1
Protected Overrides Function ProcessTabKey(ByVal forward As Boolean) As Boolean
MyBase.ProcessTabKey(forward)
End Function
End Class
Now when you run the project, you'll see that each time you press tab it skips one of the combos.

I want to set a property of an object that is an array type. If I was declaring and initialising an array of objects, I'd do this: Dim x() as SomeObject = {obj1, obj2}
I don't seems to be able to do something similar with the property, can you do this, does anyone know the correct syntax? myObj.ArrayProperty = {obj1, obj2}
I get Expression Expected Error on the first {
Infer Off
Explicit On
Strict On
Answer : myObj.ArrayProperty = New objType() {obj1, obj2}

Got a problem that's hopefully a quick fix. I've got a homework assignment where I have to link an access database file and allow the user to go through the records, add/delete records and save the file.
When I run the program everything seems to work fine, except when I hit the next button to go to the next record, it always skips 2 ahead, from 1 to 3 and 3 to 5. The previous does it also and when I click the delete it deletes 2 records. I can't figure out why it's doing this. The table we linked was already created for us so I don't believe that it is a problem with that. One weird thing I noticed is that it shows that there are 5 records so I wouldn't think that it is seeing 2 as 1.
Here is my code for the buttons:
