Hi - I'd like to dynamicaly move a button during runtime.
I've tried changing the control's Control.Location.X and .Y but get the error:
Cannot modify the return value of 'System.Windows.Forms.Control.Location' because it is not a variable.
Is there a way to move a control at run time?
Thanks, mutty

How about Control.Left or control.Top?

Well and if you want to know why you cannot change it: open reflector and see that the Location property returns the following:
return new Point(this.x, this.y);
So it is returning a new point object. If you anyway want to change the location of the control using the Location property you should feed it a new Point :
Control.Location = new Point(X,Y);

Is there a way to find out the Windows version of a machine on the network in C#? I just want the Windows version (9x, XP, etc) and which service pack.

Take a look at WMI -- you can access it with script (VBScript, JScript, Python, Ruby, etc.) or even directly from C# with a little interop. Check out Scriptomatic[^] and look around that same vicinity of TechNet for more WMI information.

How can i count the number of lines in a string also the number of bytes in a string?
|
|
|
|

The number of lines in a string is the number of occurrences of Environment.NewLine + 1. As the string class does not contain a method to count substrings you would probably have to run a for-loop over each char in the string and count.
The number of bytes of a string should be string.Length * sizeof(char).

To Count line in string
Regex rx=new Regex(Environment.NewLine);
MatchCollection mc=rx.Matches(textBox1.Text);
int lineCount=mc.Count;
Note:if the last two chars of string is not Environment.Newline
the line count will be decreased by 1 so you can check
that last two chars in the string is Environment.NewLine
If not add it
To Get the bytes in string use Encoding class
and select Encoding Format you work with
For Example
int cb=Encoding.UTF8.GetByteCount(textBox1.Text);

Just to make publicity... :-P
Some files can be Mac and Linux files, and they can have different "NewLines"... Look at this program I made, get the source code if you want!

The easiest way of counting the number of line breaks would be to remove them from the string and then check the difference in size:
lines = 1 + ((Len(text) - Len(text.Replace(Environment.NewLine, string.Empty))) / Len(Environment.NewLine));

To read the number of bytes, you can use Systm.Text.Encoding.Default.GetByteCount.
The most accurate way to count lines would probably be to use StringReader.ReadLine, but if that's too much overhead, try this function:
static int LineCount(string str)
{
int lines = 1;
for(int i = 0; i < str.Length; i++)
{
if(str[i] == '\r' || str[i] == '\n')
{
if(i+1 < str.Length && (str[i] == '\r' && str[i+1] == '\n'))
i++;
lines++;
}
}
return lines;
}

I've made a little application for opening pictures using pictureboxes. I've used File Type Editor to connect my app with .bmp. .jpg, . gif etc. file types. After instalation, when I doubleclick a picture file, my app runs, but there is no picture in pictureBox1. I know I have to do something with Arguments property, but I dont know what. I've tried:
public static void Main(string[] args)
{
Application.Run(new Form1());
args=Environment.GetCommandLineArgs();
foreach (string arg in args)
{
fajl=fajl+arg;
}
pictureBox1.Image=Image.FromFile(fajl);
}
How to make doubleclicked file apear in pictureBox1?? 
please help!

The line after Application.Run(new Form1()); will not be executed untill you close the form.You should put your code either in Form1 constructor or in form_load event handler or in form_activate event handler
for example:
public static void Main(string[] args)
{
Application.Run(new Form1(args));
}
private Form1(string[] args)
{
foreach(string arg in args)
fajl+=arg;
pictureBox1.Image=Image.FromFile(fajl);
}
P.S. remember that Form1 constructor is an instance member (not a classifier) then none of the variables within it can be static or you should use Form1.variableName to refer to them.

I have an Visual C#.NET 2003 and want to develop a "Smart Device Application", but it isn't contained in the New Project dialog.
I've also installed:
.NET Compact Framework
Microsoft Pocket PC 2003 SDK
Mobile Application Development Toolkit
But I'm still not able to create that mysterious "Smart Device Application"
If I have some TOO CHEAP edition of VS IDE, is there some alternative IDEs which support mobile development?

does anybody know how to find all reference types of given object and set them all to null state, so given object can be available for GC?
for example..
object _a = new object();
object _b = _a;
now we have two reference type objects which are pointing to the same memory block.
the thing is that I don't know anything about "_a" and would like to set it to null state somehow from "_b".
what do you think?
luke
