hi,
i tried that but it won't work and says that:
Cannot implicitly convert type 'object' to 'System.Drawing.Drawing2D.HatchStyle'
There is no SaveGame in real life.

 Sorry, I forgot the cast. The word "implicitly" should've given you a clue to explicitly cast, though.

hey i found that , thats it , just it!!! :::

What is beter convention in C#:
1) To keep each class in seperate .CS file
OR
2) Keep all classes of same namespace in a single .CS file
i know both ways work.. but just wanna know what is a better convention

One Class - One File (In my opinion)
Having all of one namespace in a single cs file could get very very crowded.

In general, what Colin said. Option 1.
Though of course enumeration classes and tightly related classes often stay in one file for me.

Same with me. I also tend to use regions in those cases, too.

Regions are a god send when you have rafts of ugly collection/enumeration code cluttering up a simple enough class.

True. I especially like them for explicit interface implementations! Sure eliminates a lot of code that probably just calls similarly named methods on the class that implements it.

One class per file, and of course real programmers use nested classes, so even then they tend to get big, hopefully .NET 2 will help out there.  It would be nice to group files according to function.

One class per file except when the classes are small, very similar or closely related.
I also put all rarely used classes in the same file.
(Like by aggregation).
God bless regions.

Try debugging your code. Put a break-point at the beginning of that case and step through your code, checking the state of variables as you step over each line. And keep in mind that using the == operator for strings results in a case-sensitive comparison. See String.Compare for a better, culture-aware comparison with many more capabilities.

String comparison
Is there any way so that all the below conditions give me true results.
String val = “Hello”
Now comparing val it with the following code.
1 “Hello “ //Note white space at the end of Hello.
2 “ Hello” //Note white space at the beginning of Hello.
3 “Hello “ //Note two white spaces left at the end.
4 “ Hello “ //Note white space both at thebegining and end of Hello.
5 “hello” //Note the caps change.
6 “HEllo” //Note the caps change.
Thanks

Look at the documentation for the String class - not reading won't teach you anything. Specifically, look at the Compare (like I mentioned before which can do case-insensitive and culture-specific comparisons) and Trim methods.

Hi friend,
I had same problem with my "Hello World" program using CP. I suggest the following:
1. Don't enter the commands in the MS-DOS mode, instead use the Visual Studio .NET Command prompt.
2. Ensure that your program is saved as as .cs "example.cs"
3. In the VS.NET command prompt type csc example.cs
The program will compile successfully if it has no bug. Then type
example (press enter). Your program begins to run.
Enjoy C#
...the mind is not a vessel to be filled but a fire to ignited

hi extremeg:
thanks for your help
i find the .exe file was create by csc application at the same folder.so,i create a shortcut of visual studio.net command prompt at desktop then i find that the .exe file was on the desktop too. these days i use this method to compile my code and view results i think your method maybe more convenient! thanks for your help... my english is so poor.. i wish that u could understand my message..

any equivalent of MAP files in C# for debugging??
Muhammad Shoaib Khan
http://geocities.com/lansolution

Not exactly like a MAP file - but serves much of the same purpose - the PDB file that is generated in a debug build contains the symbols for a debug version of an executable. While the IL for a debug assembly is pretty much the same as it is for a release assembly (barring a differences, like when you use pre-proc conditions or attribute a method with the ConditionalAttribute), the debug build contains the path to a PDB file in another file segment. These are useful in debugging and will provide method lookups, line numbers, filenames, etc.
These won't work for release builds, though.

Hi
I need some help in getting a video played in the back ground of my win form where I will add some controls that would display some text and other stuff.
What I did until know is.
Using interop and Com I am able to play the video inside a panel, but here is the problem if I add a control inside the panel ex.
This.controls.add(panel1)
This.panel1.Controls.Add(textcontrol)
When the video loads it is hiding everything in the same control (panel1) but not all the form unless I set the size of panel1 to be as the same size as the form.(I don’t want every thing to be hidden I want the controls to show over the video with an alpha transparency level )
What I did is instead of adding the textcontrol to the panel1 I am adding it to the main form so I am being able to put the text over the video, but I am losing the benefit of having an alpha (transparency) for my text.
I would weolcme any suggestion to solve this and any alternative solution
Simply what I am trying to achieve now is to have a news bar like the one that you can see on CNN by adding text over the video
Thanks for reading this.
Best regards

Most video players like Windows Media Player (which I assume you're using) show the video in a separate layer that doesn't allow them to be hosted like that, otherwise someone could easily capture the video which may or may not be protected. You can further see proof of this by trying to take a screenshot - you shouldn't see any video.
You should take a look at DirectX: http://msdn.microsoft.com/directx[^]. There's a lot more you have to do, but there are a few examples here on the CP site that should help.
