This question may have been asked before but I searched around a lot and I couldn't find the solution of what I need.Let's say I have a string like "Int(100/9)". How can I get the result I want, which is 11? I don't believe the MSScript Evaluate method would work on this one, would it?
View 15 RepliesHow come both intellisense and compiler accepts If 3 = True Then ... in VB.NET? Even with option strict on.Does it in actuality treat Booleans as Integers, or what's the deal?
View 4 RepliesToday I noticed that Visual Studio 2008 always treats a file as if it was a component or a form if this file contains a definition of one.This means that it always opens the designer by default. I think this behavior is very annoying, because a file containing a class that derives from form or control does not have to be an actual form or control and I want to edit the source by default.

View 4 RepliesI have a gridview which in one column is displaying MAC addresses. Instead of displaying them in one row, its putting them in a column as wide as the "MAC" header column.

View 1 Repliesi am running a Sub which takes as arguments a Datatable and a String.
Private Sub Populate(ByVal dttemp As DataTable, ByVal strWhichPart As String)
At one point there is a combobox which is populated with some of the data in the datatable. The name of the combobox is cmd plus the name of the string for example when the string is Person_FirstName the name of the combobox is cmbPerson_FirstName.Then i add items to the combobox like this:
cmbPerson_FirstName.Items.Add(strHold(rr))
My question is this can i make a String into a command? Because i have many comboboxes which have the same name as the string argument of the sub how can i do something like this to work
strWhichPart.Items.Add(strHold(rr))
in which strWhichPart is a string. Is there a command that i can execute a string as a command?

I've been using SQL OleDB commands to grab data from some excel files and it's working well, but I'm having a really hard time finding a good resource for the actual command strings on the web. I figure I must not be using the proper terminology in my searches. Take this line:
Dim da as New OleDb.OleDbDataAdapter("Select * From [" & sheetName & "]", Conn)
My question this morning was: Can I pass a command that will grab all sheets from the excel document instead of just one in particular?
I have a problem with the code below as a SQL command string. Note: Using .Net Framework 4.0 in Visual Studio 10 Professional. Database is a Microsoft Access file. The idea is that this SQL command string will update a password within my database. Also note that I have tried the string below with and without the ";" at the end and it does not work either way. The problem is most likely extremely obvious, but I can't seem to find it. I have commented below the code what each part of the String is.
"UPDATE Users SET Password='" & tbx1.Text & "' WHERE Username = '" & sUsername & "';"
' Users is my Table name within the Database.
' Password is the field that I want to edit within the Users table.
' tbx1.Text is where the password is stored within a text box.
' Username is the field which I would like to compare with sUsername which is a variable within the code.
Solution was square brackets, Command string now looks like this:
"UPDATE Users SET [Password]='" & tbx1.Text & "' WHERE [Username]= '" & sUsername & "'"

View 4 Replies[code]Myself and a coworker have stared at this quite a lot and we can't figure out why it's not working. The problem is in the value for @ID (since it still works when I leave the other one parameterized). The funny thing is, Just a few lines of code above it I have a different query that sets a parameterized value for the same ID, using the the same choices list that the For Each loop is getting the match variable from.Choices is a list of longs, and when I use choices(0) to parameterize ID in a query, it works. But now down here in this loop I have the new match long, and it doesn't want to make it work for me.
