Sure eliminates a lot of code that probably just calls similarly named methods on the class that implements it.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

It would be nice to group files according to function. leppie::AllocCPArticle("Zee blog"); Seen on my Campus BBS: Linux is free...coz no-one wants to pay for it. Re: C# convention!!

(Like by aggregation). God bless regions.

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.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

Thanks Re: DataGrid problem plz check Heath Stewart6-Jan-04 6:41 Heath Stewart 6-Jan-04 6:41  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.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

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.

MAP files abc8764-Jan-04 20:17 abc876 4-Jan-04 20:17  any equivalent of MAP files in C# for debugging?? Muhammad Shoaib Khan http://geocities.com/lansolution Re: MAP files Heath Stewart5-Jan-04 4:41 Heath Stewart 5-Jan-04 4:41  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.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

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 Re: custom controls and video Heath Stewart5-Jan-04 4:13 Heath Stewart 5-Jan-04 4:13  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.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

Re: READ/WRITE SECTORS, TRACKS, ECC... Heath Stewart4-Jan-04 19:01 Heath Stewart 4-Jan-04 19:01  C# - rather, the .NET base class library (BCL) - does not provide such features. This is much too low-level for the BCL. You'll have to P/Invoke native functions (see DllImportAttribute documentation for details). You should also try searching this site or googling the rest of the 'net for any examples.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

Writing a for loop that actually does what you want should be a no brainer if the comma notation is supported. BTW, I should mention that while I'll also often see how terse I can make my code, number of lines is not always an indicator of anything. Always consider before you make 6 lines of code into 2 if your code has become easier, or harder to read and maintain. Also, the shorter code does not necessarily run any faster, and may be slower.
