Pass the sort expression in the Sort DataView's Sort property.

I think this might help you :
Filtering and Sorting[^]

And to calculate the aggregate functions, I think there is also a Compute method where you can pass all the aggregate functions.

Check this :
http://msdn.microsoft.com/en-us/library/system.data.datatable.compute.aspx[^]

Other than that, you can also use LINQ to do this.

And F1 and Google are both disabled? There are loads of articles about doing this type of thing - LINQ is probably one of the easiest to use.

Use the data tables' DefaultView's Sort and RowFilter properties to order and select rows respectively!

Dataset.Tables["TableName"].DefaultView.Sort = "Column";
Dataset.Tables["TableName"].DefaultView.RowFilter = "Condition";

vb calculation is diffrent than C# calculation [modified]

Hi, I have a vb application, which contains lots of calculation and I am converting that application to asp.net C#. There are so many variables of double types in the vb application and I also took double in the c# for those variables. Now problem is that I do calculation with the same equation in both the application, however result value does not match. I have a variable var1 in vb the calculate double value is 1.63870925710649 (for vb) and 1.6387092571064941 (for c#), I do not understand why these values are different for the same datatype. And I have to use this variable in my equation, since both language has different value, this may be the reason of different final output. Some times I have to break the same equation into two or more equations for the C# , to get the same result in C# and sometimes I get the same result. But sometimes I get the value in c# which does not match the value of vb. I do not understand which calculation is right vb or C#.

Both calculations are correct, except that the precision in C# is more than precision in VB

1.63870925710649 [VB]
1.6387092571064941 [C#]

Just round off the value the number of digits required and use it!

Thanks for your replay. But this is not the problem. How do I know how much digit I have to round up. There are more than 100 double variables and more than 100 complex calculation, then its very difficult to round each and every variable or calculated value, however in vb they did not use any round method.

I understand that it can really be a pain in your scenario. How about doing the rounding off at specific check points?

BTW, what is the system precision that is expected??

Can you provide an example of a calculation which doesn't give the same results?
There are some subtle differences in math between C# and VB which could explain it.

Media player cant be created using Asp.net.

You need to use flash or silverlight or any browser component to build the media player.

Html doesnt have the capability to show video. Wink | ;)

Clearing header using Response

Hi..
the response.clear erases html output but doesnot erase any headers. i need to clear whole page.
according to MSDN

The Clear method erases any buffered HTML output. However, the Clear method erases only the response body; it does not erase response headers.

Can anybody provide some assistance on how to clear the header as well...
Thanks

Mark

Hi,

take a look in your web.config. All referenced assemblies must be listed there. Remove the entry for the System.Web.Extensions.dll version 1.0.61025.0 and try again.

Let me know if this helps.

in your Project you have referenced an Assembly with this Version 1.0.61025.0 and you opened your Project VS 2008 and Automatically it added 3.5.0.0 now you need to use one. Remove the old one that targets 2.0 <b>1.0.61025.0</b> and leave the 3.5 one. remove it in the webconfig.

You can access the textbox by accessing the master page object.

To get width and height of a image from server

Hi frnds,

I hv a code to get width and height of image in a file. Image is stored in folder and imagename in database.. I'm using asp.net 2.0 and sqlserver 2005.

Dim width,Height as integer
ImgPath = "~/Photos/" & ImgName
Dim fullSizeImg As System.Drawing.Image = System.Drawing.Image.FromFile(ImgPath)
width = fullSizeImg.Width
Height = fullSizeImg.Height

This works only in localhost. But after uploading to server it is not working. Is ther any other method to get the width and height of the image from server..?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
