Count All 1's In Row And Columns?

Feb 19, 2009

Textboxes are arranged in a 5x5 matrix and each text box is only restricted to either a "1" or "0" input. I need help in the code that will count all 1's in each row and column. Since this is a 5x5 arrangement, there are 5 rows and 5 columns each. I am actually making a simulation of a VRC/LRC program. There will be 2 buttons namely "Even/Odd Parity". If user presses Even parity and the number of 1's in that specific row/column is Even, the result will be a 0,If odd the result is 1. There is a result textbox at the end of each row/column.

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?

Regarding DataGridView Visible Columns Count?

Aug 3, 2009

i have a DataGridView bound to a table that has 22 fields in it. In the datagridview columns, the first 2 have the visible property set to false and the last 7 also set to false. This works since there are 13 columns displayed in the datagridview when the program runs. Here's where my issue come in. When I do the following, Console.WriteLine("Column count = " & DataGridView1.Columns.Count.ToString()), I get the expected "Column count = 22 in the output. However, when I do Console.WriteLine("Visible = " & DataGridView1.Columns.GetColumnCount(DataGridViewElementStates.Visible)), I get 20 instead of the expected 13 that actually have the property set to visible.

Auto-resize Columns Based On Char Count

May 11, 2009

I am trying to figure the best way to programmatically re-size table column headers in ReportViewer.Basically, my current resolution is the following: ColumnWidth = Header Caption_CharacterCount * 0.32...Where 0.32 is an estimated width of a typical character using my current font size.The issue is that the width leaves a lot of whitespace for longer captions.The more characters a caption has, the more whitespace I end up with.The issue with estimating this way is that not all characters are the same width. A good example would the the "I" character, which takes up less screen width than the rest of the alphabet.[code]

DB/Reporting :: Get A Count Of The Physical Pages (as Opposed To Logical Page Count) To Use With A Print Dialog

Jul 16, 2010

I have some reports that I use with the MS ReportViewer and I need to get a count of the physical pages (as opposed to logical page count) to use with a print dialog. I've implemented a workaround so the ReportViewer control displays the correct number of physical pages, but is there a way to get that value from the ReportViewer control? The only publicly accessible property gives the logical page count.

Original DataTable Object Has Columns Added When Variable Has Columns Added?

Oct 6, 2011

I have a datatable property called prpParametersTable in a class called clsBatch. I have a procedure that sets a datatable variable called dtP equal to prpParametersTable at the beginning of the procedure. I then add three new columns to dtP.Here is my problem. When I add the three new columns to dtP my original table prpParametersTable also gets those columns added to it, why? I only want to add the three columns to dtP and not prpParametersTable. How can I do that?

Private Function prvfnc_InsertBatchParameters(ByRef cnn As SqlConnection, ByRef trans As SqlTransaction) As String
' set new columns that have BatchID, Insert DateTime, and UserID for the SQLBulkCopy method below

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).

Convert In The "Normal Count" System And In The "Long Count" System?

Sep 7, 2011

This is not useful, but:If you like Mayan culture,This code convert an integer in Mayan numericals

It can convert in the "Normal Count" system and in the "Long Count" system.In the Normal Count", every glyph is a power of 20, with the most significant on top and the less significant at the bottom

The "Long Count" system was used in Calendar. In the "Long count", every glyph is a power of 20 except the third glyph from the bottom, which is a multiple of 360. This was done because the years were, at the begining of the Mayan culture, estimated to be 360 days.Since I couldn't find a Mayan font, the function returns a bitmap that contains the drawing of the glyphs that represent the mayan numerical
