I am having 2 unrelated problems and was hoping one of you would be able to help me.
Firstly i have just downloaded the directX SDK, I know how to include the libraries in VS6 but i'm now using 2003 and i don't know what to do to get the IDE to recognise
using System.Microsoft.DirectX;
Secondly, i am trying to use the DllImport attribute but am getting a message saying the type or namespace "DllImport" could not be found. The line of code is
[DllImport("user32.dll")]
Followed by a function definition
Any help that you guys can give me to solve these problems would be greatly appreciated.

I have figured out the DllImport problem, i wasn't including the
System.Runtime.InteropServices;
Still having the directX problem though.

1.
It sounds like you missed to add a reference for the library. The using directive only permits the use of types in a namespace, such that, you do not have to qualify the use of a type in that namespace.
To reference the library, go to the solution explorer, right-click on References and select "Add reference".
2.
You'll have to import the types of System.Runtime.InteropServices namespace to use the DllImportAttribute Class the way your doing.
using System.Runtime.InteropServices;
[DllImport("user32.dll")]
Followed by a function definition

OK, sorted the DllImport problem, thanks.
Back to directX. What you are saying is true, i am missing the reference to the assembly but, DirectX is huge, you wouldn't add a reference to each DLL manually.
In Visual Studio 6, you added a reference to the relevant library folder and include folder, then you could just use the functions as though they were system functions. In 2003, if you include the relevant libraries then you can either use the fully qualified namesapce
Microsoft.DirectX.DirectDraw etc
or have a using statement as you would with any other system library.
Anyone that knows what i am doing wrong, i have installed directX SDK 9, or knows of a good tutorial for getting up and running with managed DirectX, your help would be appreciated.

Hi all,
has anybody ever tried to edit a bitmap programatically?
I have a bitmap of a printed circuit board, but around the board are white margins.
I would like to remove the white margins in my program.
Is this possible?
Best Regards
Bernd

Of course it is. Programs like Photoshop do this all the time. The real question is how your going to detect the edge between the image and the white space you want to get rid of and what you want to do about it. DO you replace it with the green PCB or do you crop the image. There are all kinds of algorithms around for edge detection, but what will work for you is up t your own testing and research.

Thanks!
I'll have a look at this.

 I am not familiar with Discussion Forum.

What's not to understand? You go there, you post questions, you read responses and replies... You obviously got part of it right, you posted something here.
I take it you had a more specific question about some discussion forum software?

How to get the list of installed fonts corresponding to any perticular charactor set? eg. if I want to get Japanese supporting font list (corresponding to char set Shift_JIS), how to do it?
please guide
|
|
|
|

You can get a list of the installed fonts by instantiating System.Drawing.Text.InstalledFontCollection. Enumerate through the FontFamilies array property. This information won't tell you about which character set the font supports, however. Character sets and fonts are two separate things. Perhaps there's a few bits in a font file that determine which charset a font supports, but I'm not aware of any.
The only way to tell is to either try drawing a character from that charset using that font and see if it works, or create some sort of font driver that lets you dig into the actual font data, which would be quite a feat since you need to somehow use the font handle to get the actual font file and examine the structure. Also keep in mind that there's many different types of font files, so this would be a very difficult task.

First of all, this really belongs in the Web Developer forum. This forum is for questions relating to C#, which can be used to create ASP.NET web applications that parse, compile, and execute code on the server so format and stream HTML to (and other files) to the browser or other client application using HTTP.
Second, if you want to use ASP.NET, then by default the pages use the .aspx extension, not .html.
Third, by using .html extensions, you are implying that you want to do this using client-side scripting, since .html is, by default, not a CGI-parsed extension on any system without actually remapping file extensions.
Fourth, are you kidding? Passing the username and password in a query string is the most insecure method ever conceived! You might as well eliminate authentication. You pass username and passwords using POST (not GET) and you should use SSL over HTTP (HTTPS) if this is sensitive information. Even without using SSL, using POST at least doesn't store the username and password in the browser's history like this would.
After taking all that above into account, how you do this depends on what server you're using and lots of other information. Again, I suggest you ask this in the Web Developers forum.

No, it's you that don't understand. First of all, this isn't even using cookies. This is a query string, and if you have questions about ASP.NET (which your URLs didn't show at all, since they use the .html files which are typically staticly delivered on the server) they belong in the ASP.NET forum.
If you're using the HttpWebRequest to access this site, then you need to pass the query string parameters as part of the URL. If the site is using cookies, then instantiate a new CookieContainer and add a Cookie. The documentation for the HttpWebRequest.CookieContainer property in the .NET Framework SDK even gives an example of how to do this. Consulting the documentation should be the first place you check.

Dear, Sir and Madam.
I want to add PasswordChar Property which shows ****** for string which I
type in PropertyGrid Control.
Regards.

Do you mean you want asterisks to show in the PropertyGrid, or that you want a property named PasswordChar? If it's the latter, then just define it as a public property on your class. To actually make is useful you have to maintain two separate buffers (either "connected" or "disconnected") - one for the actual text and one for the displayed text.
If you want asterisks to appear in the PropertGrid itself, then there's quite a bit more work involved. You would need to shadow the property using an ICustomTypeDescriptor (in the GetProperties implementations to return a PropertyInfo object that you'd manage) or using a custom designer. I suggest before even attempting this that you read about design-time support by reading Enhancing Design-Time Support[^] in the .NET Framework SDK.
If you're wanting to do this at runtime, then I highly suggest that you do NOT use the PropertyGrid managed class. It's actually not user-friendly (try reading the Windows User Interface Guidelines some time) and you can handle password fields a lot easier with a simple TextBox (which already supports password encoding via its PasswordChar property).
