ListView.Sorting can be set to None, Ascending, or Descending, repective to how the items will be sorted.

Hope this helps. Smile | :)

I think you mean that make sure that what was entered in each column is in the correct format, which you can do with regular expressions. There are a lot of articles about it, try RegexTester.asp[^] to get you started.

Hope this helps. Smile | :)

well u can handle this situation without using regular expressions as well. You need to handle the cellValidating event of the DGV and in that u'd code somthin like this.

int i;<br />
if(e.ColumnIndex == myDGVCol1.DisplayIndex)<br />
{<br />
if(!Int32.TryParse(e.FormattedValue,out i))<br />
{<br />
  e.Cancel = true;<br />
  MessageBox.Show("It is not an integer");<br />
// or <br />
myDGV[e.ColumnIndex, e.RowIndex].ErrorText ="Whatever";<br />
}<br />
<br />
// similarly u can use the tryparse methods of DateTime classes etc<br />
<br />
}

and in order to go without taking special charaters u can use string manuipulation but I dont have the sample right now...

hope it helps

There are many AJAX frameworks and controls available now that mean you don't have to know much, if any, javascript.

Then you will need to understand javascript.

System.IO

You can then get a FileStream and write the data out.

CSV stands for Comma Seperated values, so teh layout of a CSV file is

field1,field2,field3,field4\r\n
field1,field2,field3,field4\r\n
field1,field2,field3,field4\r\n
...

so as Colin said, use regular TextWriter or other streamwriting thingies

Visual Studio can't evaluate this, can you?

public object moo<br />
        {<br />
__get { return moo; }<br />
__set { moo = value; }<br />
}

Well.... Could you explain some more? Do you want data to be organized in a table? There are articles about this such as usingdatagrid.asp[^]. Or if you mean a chart, like a bar graph or histogram, etc., CS3DCharting.asp[^] is an article that will help you on your way.
Hope this helps. Smile | :)

You can change the version number of your new setup.
It will like 1.0.0. Change it to 1.0.1
Dont forget to set the option to clear previous version.

You have setup project for your application.. right
Now goto properties of setup project. Find the UpgradeCode property from the properties list. Set the GUID for UpgradeCode.

Regex pattern

Hi.
What's the regex pattern which checks whether a string contains any digit.

Example:

code -> no match
U2 -> match
3435 -> match

Thanks.

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