I suspect you're writing a windows app ( not ASP.NET ) and need to add a reference to System.Web to your project.

Hi Numbers1thru9,
Christian has given you the one of the reasons why you face the error in the first place.
In the event you want to have a look at some simple code; I had published an aritcle titled "AlarmTimer" located at http://www.codeproject.com/csharp/abyalarmtimer.asp[^] Just some basic stuff when I intiialy started fooling around.
Hope it helps you out...
Thanks and Regards,
Aby

Ok this might sound like a very dumb questions to many ppl but I have got to understand it so ignore the dumbness of the question .
Anyways, in windows applications (for e.g. Quicken, QuickBooks, MS Money or any other data-extensive application) how and where do they store the data? Do they use a database? if they use a database then why don't they ask us to install a database engine (which should be a prerquisite - MSDE for instance)?
If they don't use database then how in the heck do they keep up with the relational data?
Your help will be appreciated . Thanks in advance.

I don't know how they store their data, but I guess it's some custom binary format.
But for your own applications you might want to use SQLite.
It's a database similar to MySQL (though lacking some feaetures) which stores a database into a single file
For C# (and .NET) you can use the Mono.Data.SQLite class in your applications

How can i play a simple wav file with my application?

Not sure if there's anything built in ( for C# 2.0, I thought there was ), but the PlaySound API can be interoped for wavs, for mp3, you can use the Windows Media Player control.

You are looking for one of these functions
[DllImport("Winmm.dll", CallingConvention=CallingConvention.Cdecl)]
static extern int sndPlaySound(IntPtr buffer, int dwFlags);
[DllImport("Winmm.dll", CharSet=CharSet.Ansi,
CallingConvention=CallingConvention.Cdecl)]
static extern int PlaySound(string filespec, int hModule, int dwFlags);

I have bound a DataTable to a DataGrid:
_ds = new System.Data.DataSet("ResultsDataSet");
_resultsTable = new System.Data.DataTable( "ResultsTable" );
_ds.Tables.Add( _resultsTable );
dataGridResults.SetDataBinding(_ds,"ResultsTable");
When the user clicks on a row, I want to get information about that row:
System.Data.DataRow currRow = _resultsTable.Rows[dataGridResults.CurrentRowIndex];
This works fine until I sort the DataGrid by clicking on the column headers. Now the dataGridResults.CurrentRowIndex is out of sync with the _resultsTable. I either need to have the DataTable sort with the DataGrid, or be able to get information directly from the DataGrid. Am I doing something wrong, or do I need to add something?

Hi,
try this:
System.Data.DataRow currRow = _resultsTable.DefaultView[dataGridResults.CurrentRowIndex].Row;

That helped. I had to tinker with it a bit more, but it is working now.
Thanks

Hi everyone,
Here's what I'm trying to do. I create a RichTextBox object and set some text (in code, I'm not adding it to the form). I want to take what it would look like and draw it onto another control (like a panel).
Am I able to do this somehow? Is it possible without Interop junk?
Thanks,
Nick Spacek

Are you trying to add one programatically created control to another programatically created control ?or are you trying to add that text box to control added Via the designer?
|
|
|
|
|
Nope, not at all. I just want to take what the RTB control would be drawing and draw it onto the panel control somehow.
|
|
|
|
|
I thought that .NET controls have a method for painting to a bitmap ?

On that note, I went searching. I managed to come across this article where they draw a web browser control onto a picture box and save it:

Thanks for idea, hopefully there's something a little more .NETish though...

No, I thought there was a framework method for rendering a control.
But, I can't see it now, so I could be wrong.

I tried this out and should have realized it wouldn't work quite the way I wanted. For this to work, I think it actually needs to be a visible control since that's the way the BitBlt works...

I'm going to ask a silly question. Why not put a RichTextBox control on the panel instead? Seems like you want to do things the hard way?

Haha, well, it's a good question. I sorta had this idea that this is the best direction to go but I could be completely wrong. Basically I want to have this panel be a media container (stupid name) or something. I stumbled upon another class here that uses DirectShow to render a video given a handle and bounding rectangle. So the idea is to use just some generic control to draw everything on. I could probably have my app switching between different controls I guess...
There's probably a completely better way to do it all. If I want to use DirectShow for videos I suppose I should use DirectX to render the text and stuff too, but then I'd have to write some sort of class for describing rich text, etc. I may go that way in the future I suppose.

hi
i want to set opacity of picturebox (like Form), But how to do ??
thanks ..
|

Don't. Instead, draw your picture directly onto the form and set the opacity that way. ImageAttributes is the class you need to create and pass in to the DrawImage method of the Graphics class in your paint method.
