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 />
}

How to make organization chart using C#?

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 | :)

any previous versions or remove them for the new installation. I use a .net setup project.

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.

My small attempt...

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.

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

Example:

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

Thanks.

What about

[0-9]{1,}

?

hi,

.*[0-9].*[0-9]?

would be one of them.

Or, String.LastIndexOfAny Method (Char[]) [^] would do.

The correct one is [0-9].
The one you mentioned checks whether the string starts with any digit.

Here is the most common usage:

foreach(object o in someEnumerableObject)
{
   // do stuff
}

Unless you meant enum in which is it used to define a list of possible values from a well defined list.

When ShowDialog() completes it returns a DialogResult. There are only a small number of possibilities for the result including Okay, Yes, No, Cancel. Instead of forcing the developer to remember the integer values of each of these results the enum can be used to provide a more meaningful way of expressing the value.

you could use Code Search[^] to find some (a bazillion) usages of foreach, and analyze and interpret them.

Visual Studio can't evaluate this, can you?

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

DataView Column Order

Pualee20-Mar-07 1:11

20-Mar-07 1:11

Hi,

I am having an issue setting the column order on a grid:

I created a DataTable with some bound and some un-bound columns.
I created a DataGridView using the DataTable for input.
I set the .DisplayIndex for all the DataGridView columns
I then created a DataView using the DataGridView.DataSource
I assigned the DataGridView.DataSource to the DataView.

My columns to not appear in the correct order when first displayed, however, if I change the row filter on the DataView by responding to a GUI event, everything updates and my columns are in order.

Also, another table using only bound columns displays correctly the first time.

Has anyone had a similar issue or want to take a crack at this problem?

Thanks in advance,
Pualee
