Hey all!
I would love to get some help with the next subject:
I have an array list of structs. The structs contain 4 fileds. Now, I need to sort the array list by one of the fileds. The disired filed, that the array should be sorted by, is given by the user.
Now I indeed created a class of the struct with the 4 fileds, and created an array list of that struct in the main class. The struct class inherit the " IComparable" interface. Now from the main class i call the sort function.
The thing is - I don't know how to "inform" the toCompare method as for with filed from the 4 fileds to sort by?
Hope you understand. Thanks.

Instead of implementing IComparable for this, make a comparer class that implements IComparer. You can make one comparer class that can handle either of the fields in the data, or you can make one comparer specific for each field. To sort, you create an instance of the comparer class and use when you call the Sort method.
Unless you are stuck with framework 1.x, you should not use ArrayList at all. Also, unless you know exactly what you are doing, a class is a better choise than a struct. Given that you talk about a "struct class" (a contradition in terms), it seems like you should do some reading up before fiddling with structs... (No offence intended.)
Despite everything, the person most likely to be fooling you next is yourself.

I need a loop statement that changes what varible it is working upon each time it loops. The loop is changing the text of a label. The thing is I got frame1, frame2, frame3 all the way to frame0 and I need it to display them one at a time. So I was wonnering how I would do this.
Would I do something like this:
int thisFrame;
thisFrame = 1; \\for first frame
\\my display code
Text = frame?;
\\at the? it somehow uses thisFrame as the number so in this example it would be frame1
Is something like the above possible and if not how do I get the desired behaviour?

Since .NET we haven't had control arrays. You can create your own though. Simply create an array of frames and add your frames to it then you can iterate through them.

Hi
This is my treeview structure
..Node 0
:...Node 1
:...Node 2
* Node 0 is parent of Node 1
* Node 1 is parent of Node 2
Now when i am selecting Node 2 most of the times the focus is shifted to its parent node i.e Node 1 ..the same thing is happening with the Node 1 focus is coming into Node 0..
Is that i am missing something any Settings or the problem is within my system.
Please check once and reply me

Hi, i have a C# project of a program. In the project i have added the windows calculator as an executable. I need to open it when a button is pressed. How can i run an *.exe from within the program?
|
|
|
|
|
Process.Start("calc.exe"); I believe (procoess.Start is definately right )

But with Process.Start() the file must be on the file system. Can i make it run without creating it - for example from a stream or from an embedded resource or from bytes???

Why, is windows calculator not on your file system ?

Use Process.Start[^], passing in the path to your executable.
