I have the following line of code which keeps giving an error.[code]I know what is causing the error, it is the ItemCount which remains as ItemCount in the command line not the value of ItemCount but I can't work out how to get the integer value.

I have some subs that I use that I could make more universal if I could have a ComboBox variable so to speak.
Me.ComboBoxCMFrac.SelectionStart = Me.ComboBoxCMFrac.Text.Length
For the above code is there a way to enter a variable that could be set to whatever ComboBox you wanted. I tried
Dim ObjectComboBox As Object
ObjectComboBox = ComboBoxCMFrac
ObjectComboBox.SelectionStart = ObjectComboBox.text.length
It doesn't accept that in the editor but I'm showing you what I would like to do. If there's no way to do it fine but if there is a way I'd like to know how.
how can i replace the enter key event present in an ASP variable with a white space i tried a lot but bad luck...Actually there is no character like vbCrlf or <br> in the string actually I am getting ...it is an enter key event present in the string taken from a textarea ..... My attacks on this issue:
replace(request("textarea"),"vbCrLf"," ")
replace(request("textarea"),"&vbCrLf"," ")
replace(request("textarea"),"Chr(10)"," ")

Is there any third party component that has to be used to solve the problem...
Say that i have the following code that parse about 20k records from the DB.
Code #1
vb.net While reader.Read()
list.Add(If(Integer.TryParse(reader(0).ToString, 0), Integer.Parse(reader(0).ToString), 0))
End While
And then another code which does the very same thing but it seems to be a little cleaner.
Code #2
vb.net While reader.Read()
Dim storeowner As Integer = 0
Integer.TryParse(reader(0).ToString, storeowner)
list.Add(storeowner)
End While
This is what i am confused about; does the compiler creates a new variable automatically when i use the if statement without strictly declared variable? What approach is better in sense of performance?
Say I have something like this
Dim Level1 as Integer = 83
Dim Goal as String
Goal = InputBox(" What level is your goal?")

I find that each time there is a new line when enter key is press in VB intellisense is annoying. Although space is ok, but each time it has a new space and I have to press return to remove it, which is also inconvienient for multiple selections.

View 2 RepliesI started learning vb 2010 over the internet for about an a week and got stuck on this assignment that I got from the internet
1.Add one textbox so the user can enter a distance measured in feet. Add labels as needed.
2.Add a button control which when clicked is converts the feet to meters (1 foot = 0.3048 meters), accepting floating point values and preserving them (no integer conversions) and display the output as shown next. 1 Points
3.Display the conversion result using a MessageBox (not msgbox) using this format: x feet is y meters, where x is the value entered and y is the result of the conversion to meters with up to 2 decimal places only. Then show an extra line of "Would you like to start another distance conversion?" and make the No button the default in the message popup and display the question icon.
4. If the user chooses Yes, cleanup the controls as in the Reset button. 0.5 Point
5.If the user clicks no, ask in another MessageBox if the user wants to quit.
6.If the user chooses to quit, close the window, otherwise no action is required.
I have to create an application that lets a user enter as much grades he wants. The grades are between 0 and 100 and they can't be negative. Whenever the user type -1, the application is done and it shows the average of the grades, the lowest and the highest grades.I absolutly have no idea where to start but i must be using loop/do/while.

I can select any other item from the table without the error. "sender" has the same properties as "receiver" in the SQL table.
So I have an arraylist with some strings in it in one private sub. But I would like to use this same arraylist in a different private sub also. How could I accomplish this?
I tried changing the subs to public but still got the "is not declared" error. And I tried switching the arraylist's dim with public only to get another error.
