Threading in C#

Hi,
I have a web application wherein I need to call an outside DLL which executes a function call which is taking a lot of time. So what I need to do is that upon page_load of the application, I spwan a new thread which will call that function in the DLL and start initializing it.
Now, when the user actually goes to the page and requests another function from the same DLL, the 2nd thread which has been spun earlier would have almost done with initialization or getting it to completion. So this main thread should then wait for the 2nd thread to complete its initialization task at hand and when its done, it should take over from that and do normal web page and code processing further.

How do I do this? Which Threading methods do i use ?
Pls guide me as I am totally new to multi threading.
Thanks
Omkar

Some browsers prevent popups depending on the security level of the browser Firefox is a good example. It's a settings issue.

Hi there,

Does anybody know a possibility to read the Video and Audiostream of a network and write it into an avi file in realtime using C# ? Audio and Video Streams must be multiplexed from different sources from the network.

It would be great if anybody knows a solution how to do that. If it is possible please insert also links or something else.

Thx!

It already is, open your project directory and take a look in the bin\Debug or bin\Release folders. Note if you want the release version then select the solution node in the Solution Explorer Pane and change Active Config to Release.

Just Google it.

Sorting columns in listviews

Hello!

I have been trying to use some of the examples on sorting columns in listviews that are published on for example http://www.codeproject.com/cs/miscctrl/ListViewColumnSorter.asp[^]and some other places but I keep getting this error:

Error 1 Using the generic type 'System.Collections.Generic.IComparer<t>' requires '1' type arguments

I guess it something that has changed with later versions of C# and I wonder if anyone knows how to solve this?

Best regards,
Hampus

You need provide a generic type argument for your IComparer, e.g.

IComparer<int> comparer = new MyIntComparer();

The <int> bit is the bit you seem to be missing, note this is just an example.

Just Google it.

All this info is just to give you an idea of what I want to do since I'm not too sure what the technical term for the procedure is. Also, whenever I move the installer out of the directory that the icons are in, it'll produce the errors and i'm wondering how to fix it to where no matter where the installer is, it shows the icons. Sorry i'm a newb.

Any help is greatly appreciated and if I have any other code wrong please inform me.

A System.Windows.Forms.Form object got a Text property, which is the title of the window.

If you're in the class derived from Form (for example in the Load event handler), you can set the title text by

this.Text = "New titlebar text";

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

DataGrid sort problem

25-Sep-06 3:21

Hello, here is my problem. I have a DataGrid control with some columns. My question is about two of them. When I enter a value in any cell of the first column I want to calaculate (by expression) the value of the second column by using the value of the first column in the same row. OK, I have a function which does that and works fine, but when I click to sort the DataGrid it doesn't work correct. I use DataView to navigate through the records in a DataTable. All of the columns are in this DataTable. Where do I make a mistake? Can somebody help?
