VS 2008 Display String In A Integer Column In A DataGridView?

Nov 8, 2009

I'm just wondering if it's possible to display a string in a integer column in a DataGridView? The reason I'm asking is that I have a column wich displays the place for each runner (it's a sports application). And if the runner is disqualified, it will display "DSQ" instead of the place.

Now, if I want to sort by clicking the column header, there's a problem if there are more than 10 runners. If there are like 12 runners, the sorting will be like this:

Feb 5, 2011

I would like to know how can I use (read and write) a value in each of my forms. To make it clear: I have 2 forms, Form1 and Form2. I've a string, called string1. If I use in Class Form1 (e.g. at Form1 load) Dim String1 As String, Form2 can't read or change it, because it only exists in Form1. So I would like to have a, let say "general value", a (for example) string, which every form can read&write.

Change This Checksum Function To Accept An Integer Input Instead Of A String?

Dec 31, 2009

This function doesn't work if I change the input argument 'pdu' from a string to an int.Would someone please help me figure out what to do here so that the checksum does not add the ascii value of the int argument but rather the actual integer value?I took out a few lines of the actual function but it adds the input argument to a packet sent out via TCP protocol.This function shows the integer value just fine in the string that gets encoded as a byte array. the checksum is wrong.!

''Public Function buildpacket(pdu As Integer) is what I want.
Public Function buildpacket(pdu As String)
Dim packet As String

DataGridView - How To Change Connection String Or Database

Mar 14, 2010

I'm trying to add a datagridview in vb.net, but it does not allow me to change the connection string or the database that should be imported to connect to it. The only thing that I'm seeing is the previous ms sql database that I connected with datagridview and everytime I click the new connection, the window closes and it leaves me with the datagridview with the previous connection that I have. And its not applicable because, now I want to connect it with mysql. Not ms sql. Its some sort of a cache like feature in vb.net, how do I get rid of it. so that I can add the new connection for mysql? Do I need to reinstall visual studio 2008?

Basic Array Construction - One Column Or Entry Would Be A Single Integer

Oct 27, 2009

How you might construct an array like the following: one column or entry would be a single integer, like 0, 1, 2, 3, 4... - i need this as an index of each one's position in the list the second would be 0 or 1, or true or false the third would itself be a list of integers 0,4,5,2,7,2,5,2...

So all together one entry would be {0; 0; 0,4,5,2,7,2,5,2} while the next might be {1; 0; 6,8,2,5,2,3}

I'm having a terrible time wrapping my head around this. It's mostly the third column which is actually a list in itself, that is giving me trouble
