Declare some class level variables that will keep track of the sums for each column. For example:
[Code]....
During the RowDataBound event, retrieve the data from each column and add it to the appropriate sum. I'm not sure if you are developing an ASP.NET application or a Win-forms desktop application so I cannot help you any further at this point. What have you tried so far to solve the problem?
I have a fair bit of experience with VB.NET and C# (In this case I chose VB.NET, blame my laziness), but I do most of my professional work using PHP. I have no experience what so ever in using any database with VB.NET let alone MySQL.Just FYI, at the moment I am only trying to Query the database to gather the information required to activate. The Activation wizard and algorithm building (which is finished anyway), and everything else will come soon. I chose the MySQL database because I have experience with it, and it seems the best option for remote usage.The whole idea already works in PHP, I'm just have major issues moving it accross into VB.NET (Using the MySQL Connector.NET);I understand the basics, and all I need to know how to do is Count Rows and gain access to the other information in a row based on provoided information (in PHP, through mysql_ result)
So, here goes nothing, this is the Query code I am using in PHP to complete the job I want to do in VB.NET. [code] As you can see, I basically need to get the PHP code into VB.NET to fit into the 'btnQueryDB.Click' Command in VB.NET. By Equivalent, the Product ID in VB.NET will come from 'txtPID' and similar, Serial Number will come from txtSNUM. Once counted to be 1, the Activation Code and Status will be fed into 2 other text boxes in the form. (acCode, and acStatus).

View 7 RepliesI've run into a bit of a roadblock trying to figure out how to programmatically not allow the same data in multiple comboboxes. I'm usnig VS2008 and I have 3 comboboxes on a form, all with the same data, say "apple", "orange", and "red". The comboboxes are nothing more than a user definable sorting method on which gets calculated first. When I use the .SelectedItemChanged event on any of these, I'll obviously be duplicating. Any idea on how I can program to automatically switch the combobox that is duplicated to the value that is missing? I don't want to hard code it as further down the road I will have up to 7 comboboxes. Below is what I started with coding. Not sure if it is the best way to go about it, but it works on 4 of the 6 combinations.

I would like to know the faster method to copy all the data from DataGridView1 to DataGridView2 Is this possible without using any loop? DataGridView1 is not bind to any database, is just filled using
DataGridView1.Item(1, 1).Value = "Data1"
I tried to simply assign
DataGridView1 = DataGridView2
it work, it copy all the data, but it doesnt show this data in the component on the form?
My DataGridView1 does not show the data on my testdb.mdb i need to fix this first before i continue on adding records on my db.
Imports System.Data.OleDb

I have a mvc 3 app that uses EF. In one function I need to get a count of rows that match a statement. I thought I could just do it like this:
Dim _ClassCount As Integer = _CurrRegistrants.Where(Function(c) c.tues_class = _CurrCourse.course_ref).Count
But that stays at 0 even when there are 40 records that match the criteria.. I think I have the right idea I just need to change the syntax a little..
Dim _CurrRegistrants As List(Of reg_classes) = db.reg_classes.ToList
For Each Course In _courses.Where(Function(a) a.course_day = "Tuesday")
Dim _CurrCourse As cours = Course

View 10 Replieshow I would count the rows in an excel document until a row has no text. For example:
A1 has a value of 1
A2 has a value of 2
A3 has a value of 3
A4 is blank
So what I want is to count the rows until there is no value. For this example it would stop at A3 because there is no value in A4
MsgBox(MyDataSet.mytable.Rows.Count)
Gives 0, why?
The table has data!
