Count Rows For Particular Columns If No Data Then Ignore And Count

Oct 6, 2010

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?

MySQL Count Rows Count Rows And Gain Access To Other Information In A Row Based On Provoided Information

Oct 8, 2009

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).

Save Multiple Rows On Data Grid?

Mar 15, 2011

<VB.Net 2010 + SQL Server 2008 + Linq To Sql>

Let's say I have ten rows on a data grid and I have changed data of three rows.

I am trying to save data by Linq for those three rows, but I am not sure how it is possible to save them.

I can do it by looping whole rows by checking each row for any change.

Is there any smarter way rather than looping by code, such as For Next.

Select Multiple Rows In Data Grid View And Loop A Sub With The Values?

May 19, 2010

I am almost there but for some reason I don't find the answer to my issue. Here it goes. In my application I have a form which displays a data grid view with some info I get through XML from a web server. The data grid view have as first column a Check Box colum. The second column have the information I get into a variable (from cells), one by one, to pass it to the sub with the XML command.

What I want to do is to be able to select all the rows and send the cell info of the second row (only for the selected rows) to my sub which will execute once then send the second cell info and execute the sub and so on until all the loop is complete. Currently my code works only if I delete one row at a time (sending the XML code will delete the info in the web server and update the datagridview which in return will remove the item).

Get A Row Count And Post That Back To The Grid

Oct 1, 2009

Ok, so I have a small program I am building for my boss to keep track of workers at certain job sites. With the way the economy is going my boss wants to track who is showing up at specific sites (jobs) and try to even it out among all the employees - some are not working full time.

Anyway, I have two Access tables linked together with the main table being Employee Data. The second Table is Employee Jobs. Basically I have three forms. The main form on startup will show all of the employees in the company - this is basically a list of all added employees into the database (this is the second form - adding employee info). At a quick glance I would like to have the initial startup form, with grid - show employee info, show the number of jobs each employee has been assigned to. Would this be an SQL statement? How to I get a row count and post that back to the grid so it shows up on startup?

Asp.net Mvc - Getting A Count Of Rows That Match In Mvc 3 Using EF

Oct 24, 2011

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

Data Grid View Header Grid Color

This is a VB .NET application where we are showing the output of a SQL statement in a Datagrid view. using .NET 2005.We need to get the seperators of the headers on the grid control to be the same colors as the GridColor on the form. See the picture below:We've tried looking through all of the properties of the DataGridView control, and found some interesting things that looked promising such as the DataGridViewAdvancedHeaderStyle, and DataGridViewHeaderBorderStyle, but none of it seems to allow you to change the colors on it.Does anyone know how to do this without remaking the entire thing with a GDI+ control?
