No code...
Just by running your query on the Enterprise Manager and on the Query Analizer apps.
Maybe it's a version thing.

Found it on this dude's blog:
http://sqljunkies.com/WebLog/sqldude/archive/2004/06/14/3146.aspx[^]
Quoting:
Now to obtain the current number of connections to the server, you can use:
SELECT COUNT(*) AS CONNECTIONS FROM master..sysprocesses
And just to get the user connections, omitting the system processes, use:
SELECT cntr_value AS User_Connections FROM master..sysperfinfo as p
WHERE p.object_name = 'SQLServer:General Statistics' And p.counter_name = 'User Connections'
Thanks anyway.

Hi all,
So I have a Bitmap field, now I want to save it to disk, BUT if it has
some transparent pixels, I want to save it as a gif, else save as
jpg.
Sounds reasonable?
How can I do that?
Thanks in advance,
Danny

There is no such thing a transparent pixels in a bitmap. There's only transparency support in file formats, and in code that sets bitmasks.
The png file format has transparency built in, but when you load a bitmap object it doesn't have support for transparency, it's just not part of the format.

Okay, so maybe my approach is wrong..
Situation:
The user opened an image file, and I load it to a Bitmap, but I don't know if the image has some transparent regions.
Now, regardless to the original user's image file's format, I want to save the image to disk, Image.Save (String, ImageFormat).
So if the original image had some transparent regions, I would want to use an ImageFormat that has support for transparency (png/gif), and if there were no transparent regions, I would use Jpeg.
Questions:
Does this requirement make sense?
How can I handle this kind of situation?
Thanks,
Danny

Hello,
I have a userControl that has a string property. I want that, instead of typing in this property, the user gets a comboBox with strings got from a database.
I've created a new class that has a GetStandardValues method, like this:
public override System.ComponentModel.TypeConverter.StandardValuesCollection GetStandardValues(ITypeDescriptorContext context)
{
ArrayList permissions = new ArrayList();
permissions.Add("test1");
permissions.Add("test2");
permissions.Add("test3");
return new StandardValuesCollection(permissions);
}
When I set the typeConverter of the property at my userControl to be the type of the above class, it works. The control's property diplays the test strings in a comboBox.
But when I try to bring this strings from a dataBase, it doesn't work.
I've already tried this:
public override System.ComponentModel.TypeConverter.StandardValuesCollection GetStandardValues(ITypeDescriptorContext context)
{
ArrayList permissions = DataBase.GetPermissions();
return new StandardValuesCollection(permissions);
}
Anybody has can help me?
Thanks
Peterson

What do you mean "it doesn't work?" Does it throw an error, does it return nothing? When posting a question be as descriptive as possible.

Have you tried setting a breakpoint on the return to see what the values in your permissions ArrayList? If it doesn't throw an error, maybe you aren't returning anything from your database.

Hello,
When I said it doesn't work, I get an NullReferenceException. But, if I put the same code somewhere else and try it in runtime, it works perfectly. It returns all the strings I want from the database. So, the code is right, but doesn't work in design mode, with the usercontrol.
I get the NullReferenceException at the line
ArrayList permissions = DataBase.GetPermissions();
Thanks

Peterson Luiz,
I think you just answered your own question. By the sounds of it, you're trying to view information in design mode when you don't have a database connection.
Either, put the below at the top of your method to stop the method accessing the database:
If (DesignMode)<br />
return;
OR. When ever you call the object DataBase, check if its null and create a new instance.
Regards,
Gareth.

Hi,
How do we decide which data provider to use from ADO.NET?
How do I decide if I need to use SQLClient or Oledb data provider for my SQL Server database.
The answer that I got for this question from my collegues is that "coz SQL Client is optimized to be used for SQL Server", is that the only reason?
Regards,
Blumen

Hi Blumen,
Yes, the SQL set of classes are designed for SQL Server and the OleDb are for Access.

Gareth.

OleDB uses OLE DB providers underneath which can connect to SQL Server, Access, CSV files and so on. It was not solely or optimised "for Access" as you seem to imply.

So whats the point in having so many data providers, ODBC for example?

That is why I hate people who do the whole social networking thing, such as facebook or myspace. 95% of them are just pathetic, very un-intelligent people who are begging to be accepting and "definded" by anyone or anything. These are the people who have to add 100's of people to their "friends list," people whom they don't or barely know. They think that their MySpace page layout, graphics, and the sh*tty music they play there says a lot about their personality.

Have tried searching Google[^]? As I saw someone say yesterday, one of the most important skills a developer should have, is the ability to research on your own.
