Asp.net - Set Label Text To Total Row Count Of Gridview?

Jun 3, 2010

I'm using a stored procedure in a sql database as the data source for a SqlDataSourceControl on my .aspx page. I'm then using the SqlDataSourceControl as the data source for a gridview on my page. Paging is set to true on the gridview. What i would like to do is set the text of a label to the total number of rows in the gridview. I can use this code

'labelRowCount.Text = GridView2.Rows.Count & " layers found"

to return the number of results per page, but it doesn't give me the total.

Converting PDF To Multipage Tiff

Mar 22, 2011

I have created a simple database programme in VB2010 Express. There is one table called stock_main_table and one 'child' table called Stock_issue_table. The main part essentailly holds the part number and the issue makes a record of each time that part is used. Its a one to many type arrangement.In the main table I have a PRI key called ID_Number and in the child I have a field called 'control'. The control has a relationship with the PRI key in the main table. So each time you create a new line in the child datagrid you retain the same number for that record. All standard simple stuff.

When I run the programme the main table comes up OK and the datagrid for the child comes up OK. If I add a record, I can add plenty of children to it no problem. The records all save OK. You can amend a record as well without an issue. The trouble comes as soon as you DELETE a record and then hit save. The DELETE seems to work and the records (parent and child) all disappear, but as soon as you try to save you get a The DELETE statement conflicted with the REFERENCE constraint error. I have tried and tried to fix this but can't.This is the full text of the exception, if anyone needs anything else then please just ask and I will post it. There is no code with this other than what is created when the dataset is dragged onto the form

Converting PDF To Multipage TIFF File?

Jan 4, 2012

I am trying to figure out a way to convert a pdf, that could have multiple pages, into a multi page tiff file. I realize there are 3rd party programs that could do this but I need to be able to do it through code. I found this code snippet but am having problems with it because I am missing namespaces, I think. I do have a reference to the Adobe Acrobat 10.0 Type Library.

Scan Images And Combine To A Single Multipage Tif File?

Jan 6, 2012

I had a related question running on this in a different thread,but I was told to start a new thread since the original had gotten off the original topic. I am trying to scan multiple pages from an Automatic Document Feeder Scanner and combine them to a singlemulti-page tif file. I am using two different third party libraries to do this.The first library I am using is to scan the documents. It saves the files to the local hard drive as single page tif files. This library returns the file-names as they were saved on the hard drive. This part seems to be working as advertised. The sourcefor this including a video on how to use it is at:

Dim FileNames As Collection
Dim FileArray As New List(Of String)

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.

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
