I tried to open it but Visual Studio 2005 Pro said it doesn't support .csproj files. 
Plus I can't run the exe's in the Debug folder.

Visual Studio 2005 does support .csproj files, unless you explicitly said not to install it during installation.

Yeah I know VS2005 supports .csproj files, I use C# all the time.

It just uses the libraries that Windows Media Player uses. It does not create an instance of Windows Media Player itself to play the files.

Hi all,
Well i want to draw a State Transition Diagram for my Java Application. Does any one got idea if there is any specific tool to create this diagram or do we have to do it on a paper.
Sorry for posting it here.
Thanks

Interesting. Posting a request for a Java application in the C# forum. Hoo boy - you must really want people to flame on you about this.
Anyway - you can do State Transition diagrams in Visio. You need to create a UML diagram and then select the UML Statechart tab in the shapes selection.

Hi
I came across this problem while working on a loop which selects from a datatable. I am selecting from a datatable which has about 31K records. I am checking to see if a column value is null. If I am not selecting based on COLUMN IS NULL, then datatable.Select method works nice. However, if I look for null column values, the speed decreases substantially(i.e from seconds to about 30 to 40 minutes).
I found a work around by replacing all null values with empty strings which solved the problem. However, if datatable column type was something other than string then this solution would not work.
I was wondering if someone has an idea about this.
Here is the sample of my code:
I have replaced the dt datatable col4 values with empty strings for now(for better performance. I want to find a better way of doing select). As a result, the code looks like this.
foreach (DataRow dr in dt.Rows)//31K records
{
col1 = dr["col1"].ToString().Trim();
col2 = dr["col2"].ToString().Trim();
col3 = dr["col3"].ToString().Trim();
col4 = dr ["col4"].ToString().Trim();
if (col4 == "") // if column4 is null then use this
{
recordsSelected = dt.Select("col2 = " + "'" + col2 + "'" + " And col1 = " + "'" + col1 + "'" + " And col3 = " + "'" + col3+ "'" + " And col4 = ''");
//recordsSelected = dt.Select("col2 = " + "'" + col2 + "'" + " And col1 = " + "'" + col1 + "'" + " And col3 = " + "'" + col3+ "'" + " And col4 is null"); <--very slow due to col4 is null
}
else
{
recordsSelected = dt.Select("col2 = " + "'" + col2 + "'" + " And col1 = " + "'" + col1 + "'" + " col3 = " + "'" + col3 + "'" + " And col4 = " + "'" + col4 + "'");
}
}
Thanks

did you try
<br />
col1 = dr["col1"].ToString().Trim();<br />
col2 = dr["col2"].ToString().Trim();<br />
col3 = dr["col3"].ToString().Trim();<br />
<br />
if( dr["col4"] == DBNull.Value )<br />
{<br />
recordsSelected = dt.Select("col2 = " + "'" + col2 + "'" + " And col1 = " + "'" + col1 + "'" + " And col3 = " + "'" + col3+ "'" + " And col4 = ''"); <br />
}<br />
else<br />
{<br />
col4 = dr ["col4"].ToString().Trim(); <br />
recordsSelected = dt.Select("col2 = " + "'" + col2 + "'" + " And col1 = " + "'" + col1 + "'" + " col3 = " + "'" + col3 + "'" + " And col4 = " + "'" + col4 + "'");<br />
}<br />

I already tried that. If you read my post I have that select line already in my code. I want to find out a work around. I replaced all nulls to the empty strings. However, this approach may not work if a column i am looking for is not string. As a result, if someone knows a better way or other way to select if values are null in datatable.
Thanks

I can't image that a real null value in the column, and comparing that to DBNull.Value would take longer than doing the string comparision you are doing now. What you are doing sounds like bad design work. I think you need to go back, and set all those columns to null, and compare them to DBNull.Value.

If I was not clear enough, the problem is when i am trying to select the data from datatable using datatable.select(). If i have null value in one of the column in datatable and i am selecting from the datatable like: datatable.select("col4 is null").
That is where it takes longer time.
Please, look at my original post
this line is not creating overhead: if (col4 == "") // if column4 is null then use this
But, this line does:
dt.Select("col2 = " + "'" + col2 + "'" + " And col1 = " + "'" + col1 + "'" + " And col3 = " + "'" + col3+ "'" + " And col4 is null");
Thanks

The only person who is going to know that is you. Does the app run?? Does it do what you epect it to do?? Only when you have a working version can you go back and rewrite it from scratch to eliminate all the "funk" that the converter added for you.

Having two options with the same name is confusing to clients. How can the client tell which Joe he or she is selecting? If it is by which appears first in the list, then you should prepend everyone's name in the list with the list item number. Having two identical options is a design flaw that needs to be addressed here, not the fact that c# doesn't allow you to implement it (IMO).

I have started on an astrology program and need to get up to speed with C# graphics and drawing. Some of the things I need to figure out are how to:
1. Draw a chart
2. List aspect images together with the planet images that form a triangle
3. Print all the above aswell
Is there any good book that can help me? Any sources on the internet? Anyone who did a similar program before? Thanks to everyone in advance, who can give me some advice!!!

If it can be done, I'm sure you wouldn't ask us for help if it were to, say, be answered by the first result when searching google for c# computer name change[^]

You might want to not lean on the Enter key when you type your posts...
The only way to change the computer name is to call the Win32 API function SetComputerNameEx[^], or if you just need to change the NetBIOS name, SetComputerName[^]. Changing the computer name requires a restart of the machine for the change to take effect.

This one is tricky, that's for sure. I'm looking for a way to generate strings based on a regular expression.
I tried several searches on google and the only stuff that turned up was a library called Grail+ and some perl module genex.
Before I'm going to hack my way into integrating perl into my C# application I want to make sure that I haven't missed a library that does what I need.
Is there anyone who has done this before or knows a library which can help me with this?

Are you just trying to generate random strings that match the regex? What could this possibly be used for? I doubt such functionality is already in the .Net framework, but I am not certain. You could create your own state machine based on a regex, then getting a random string is done trivially by randomly choosing paths from one state to another until you arrive at one of the success states (unless you want to bound or specify the resulting string's length). Anyway, good luck, and let us know if you find a solution elsewhere.
