yeah, but I kind of like typing the code in by myself.

There's a word for this: Masochism.
Sure, you can build .NET applications using Notepad and csc.exe, but why not use the possibilities the platform gives you?

OK, I finally got VS to install on my computer.
If I had a sig, it would probably go here.

What does [STAThread] mean? I've seen it in examples, and I was wondering what it was.

Windows has a notion of "Appartments"; STA stands for Single Threaded Appartment,
MTA for Multi Threaded Appartment.
It is a complex matter. IIRC in general MTA will allow for more concurrency between threads
(and more concurrency problems), whereas STA enforces several things to happen
sequentially, such as several threads accessing the same COM object.
Either read up on "Appartment model", or wait for it to become really relevant to you,
then study it in detail...

This is kind of a tough problem... I'm trying to make a function that will give me the point (in x, y format) on a circle at x degrees. I was thinking somewhere along the lines of...
public Point GetPointOnCircle(int circleX, int circleY, int circleWidth, int circleHeight, int degrees) {
return new Point(x, y);
}
I've tried to make it on my own, but it's just not working for me... Does anyone have any ideas?

The way to do this is trig. If you know the centre point, then you can build right angle triangles from there and use trig to determine both the x and y point of the triangle for a given angle, use the radius as the length of the hypotenuse. In this way, you can plot your points by stepping around in a circle.

It's not tough at all if you've done some algebra in high-school.
What you want is to convert polar coordinates to rectangular coordinates.
Skipping all the explanations, the coordinates of the point will be:
x = r * cos(u)
y = r * sin(u)
,where r is the radius of the circle and u is the angle measured beginning from "3 o'clock" and going counterclockwise.

One small additional hint: the angle has to be in radians ( 0 - 2*π ), not degrees.
I think this must be said because max12345 seems not to be familiar with elementary trigonometry at all.

I am attempting to write an image (System.Drawing.Image) to a MemoryStream using the supplied Image.Save(Stream, Format) command. I am doing this to add the image as an attachment to an email to be sent later. However the save command appears to be having no effect as the stream is empty after the command is executed. If someone could help me or tell me a better way to do this it would be greatly appreciated.
This is the code:
MemoryStream stream = new MemoryStream();
picture.Save(stream, picture.RawFormat);
int x;
while ((x = stream.ReadByte()) != -1)
Console.Write(x); //nothing get written
//Attachment attachment =
// new Attachment(stream, "Picture.jpg", "image/jpeg");
|
|
|
|
|
If you want to read from the stream, you have to reset the position in the stream. You don't have to read from the MemoryStream to get the bytes, though, just use the GetBuffer method.

Hi,
This is more of a question than a problem. I'll be starting to create a piece of software that will need to be run on a PDA or mobile phone. The question is:
Do i need to code any differently from a windows exe to a mobile device in C#?
The reason for asking is because i've never looked into coding for any type of mobile device before and just wondered are there any major differences etc.
Regards,
Gareth.

We actually have a mobile development board which might be more helpfull.

Just go to the toolbox, click on the Button control, and drag it to your form. I am assuming you are using visual studio, right?

Hi Paul, i dont want to makea general, i want to make a custom ActiveX control (which i used in other applications also by adding the dll of this control). Yes i m using Visual Studio 2005.
plz refer me some good link and help me.

You did add a reference to your custom ActiveX control, didn't you? You could always add it into the Toolbox so you can drag and drop it onto your form.

I also try to figure it out daku1..i use Session.RemoveAll() in my logout page and redirect it to my login page. But if i push back button in my browser it redirect me to my last page(for example: viewpage.aspx),and in that page i try to push my link page or any button and it tell me must to login first.
Did u already have a session check in all your web pages, that tell user to login first if the session is null?
Regard,

Does anyone know of a class that can convert a string in the c# string literal format to a regular .NET string and vice versa? I want to have a designable string property that allows special characters and I figure a TypeConverter that supports the c# string literal format is probably the easiest way to do it, unless there exists a better way?
Thanks
|
|
|
|
|
Maybe some examples of the required conversion would be helpful...
