I have two arrays
name[]={a,b,c}
value[]={1,2,3}
My requirement is to define a class as
myclass/*myclass will contain members as specified by name[] array*/
{
string a;
string b;
string c:
}
at runtime
and to create an object of myclass ,say myobj
and set
myobj.a=1;
myobj.b=2;
myobj.c=3;
Point to note is that name[] and value[] array can be of any size and contain
any value.They are not hard coded.
I am at my wit's end to solve this problem.Please help.

You need C# 3.0, it would handle this, no trouble.
Why not use a dictionary to define variables like this ?

I have organized my files in such a way that I place them in different folders based on their category. My main problem now is using those files from other folders, how can I achieve this? Thanks very much

Just include them in your project, optionally creating the folder structure also.

I have read that we can use namespaces to package C# classes. Different Classes can then be recognized by any class which includes the namespace. I have a problem however, there are 2 files, let's name them file1.cs and file2.cs. Both of them use the namespace Project.
Location of file1 --> (these are folders)Project->Main->file1.cs
Location of file2 --> Project-->MenuForms-->Cells
file1 does not recognize file2 although they are named with the same namespace...How can I solve this problem?
Really Need help... thanks!

Are they built differently too? If project A needs to use code from project B and C, just go to references->add reference, and add the two .dll's from B and C. Even better, use build events to copy the .dll's into a directory in project A's folder, that way they're always there, no matter where you put project B or C.

If you created them in these folders, the default namespaces are not the same. Have you made sure that they are ? Have you tried explicitly scoping the namespace ? Are the classes in the two files both public ?

Hello,
I have a question I've been trying to answer and I just can't find anything. When I use an interop method, I know I must put it inside a NativeMethods class. I'm writing a little utility library for my company and I was wondering where should that NativeMethods class go: inside the class that uses it as a nested type, or only one globally for all classes that use any interop method in it?
By the way, can anyone explain to me what's the difference between SafeNativeMethods, UnsafeNativeMethods, and NativeMethods? I just don't understand what MSDN says.

You can group nativemethods in different classes.
for example, process related methods in NativeProcessMethods, GDI related methods in NativeGDIMethods.
where to put these classes is a raltive issue dependent in your design.
But I prefer to put all native methods classes in a class library to use it in another porject in the future to avoid rewriting the code.
Hope this helps

Interesting comments, thanks!!
Yes, I think I'll move everything into a global class for easier reusability, with hopes that the library will grow.

Hello All,
Actually I want to port a windows application written in C# to a user control so that i can embed that control in a web browser and be facilitated from all its feature without installing it.(Only the .Net framework is required).
Its working fine but gives me exception when i go beyond the scope of the browser for example i want to save a file in C:\ drive and do some registry operations.
It gives me System.Security.Permissions.FileIoPermission and etc.
Please tell me how to set all the permissions for this control so that i can have full control over the machine on which this control is running in a web browser.
Thanks alot in advance,
Best Regards,
Rizwan Ahmed.

Hi I need to active a remote class with remoting but I need a class object that retrieves remote satellite resource messages with my client UICulture not remote assembly default culture.
How can I perform that? Is posible to activate a remote object with my custom client culture like CreateInstance method (GetObject() method dosent let me to do that)?
Than you!!!

I need to move a string of hex characters to a byte array. Here is my code:
Encoding en = Encoding.ASCII;<br />
byte[] HBReply = new byte[30];<br />
HBReply = en.GetBytes("\xFF\x00\xAA\x55");<br />
return HBReply;<br />
Is there a better way to do this? And I'm not seeing the hex characters when I do a quick watch on HBReply.
Thanks for the help.

You probably need to remove the quotes in GetBytes(\xFF\x00\xAA\x55).

What do you mean by "a string of hex characters"? Once the characters are in the string, there is nothing hexadecimal about them.
How do you do a "quick watch" on the array? It doesn't contain any characters at all, it's a byte array, not a char array.
The byte array will contain the ASCII codes of the characters in the string, which will be exactly the same as if the array was created with:
byte[] HBReply = new byte[] {255, 0, 170, 85};
Let's simplify the code somewhat, by the way. There is no need to create more than one byte array.
byte[] HBReply = Encoding.ASCII.GetBytes("\xFF\x00\xAA\x55");<br />
return HBReply;

Each character in the sting array is a hex value. I need to show the character related to that value......Okay let me explain. I'm writing an interface that communicates over tcp/ip from a PC to a Mainframe. Everything must be sent in a byte array over this connection. However I'm having trouble creating the heartbeat which begins with hex ff00aa55.

While stepping thru my code i right click on the array HBReply and see what's in it.

Tom,
I think I found your problem. You use the System.Text.Encoding.ASCII encoder which, by definition in the .NET platform, is a seven-bit text representation. From the documentation:ASCII characters are limited to the lowest 128 Unicode characters, from U+0000 to U+007f. To do what you want, try the following:
System.Text.Encoding en = System.Text.Encoding.Unicode;
byte[] HBReply = new byte[ 30 ];
byte[] buffer = null;
string s = "\xFF\x00\xAA\x55";
buffer = en.GetBytes( s );
for( int i = 0; i < buffer.Length; i += 2 )
{
HBReply[ i / 2 ] = buffer[ i ];
}
return HBReply;This encodes the string as Unicode, gets every other entry, and puts that into the HBReply array.

If you need a byte array with those values, just create that array. There is no need to mess around with a string. I showed the code for it in my previous post.

i make a project about image processing. I want to make image layers in program. How can i make it ? any idea ?

You'll need to create a bitmap for each layer, either make one color that you don't allow on the bitmap ( for masking ) or manage your own masks, and do your own merging of layers to show your image.

thanks Christian...
it is a good idea but it doesnt fit my application. When i refresh all bitmaps to draw on the form, it flickers. I need layer which can be refresh on itself so i dont need to refresh all layers.
Any idea about this...
