I can see what you're saying. Certainly the code I posted an be cleaned up and made more efficient. I was working on this last night, and what I posted was written at 1 in the morning. It worked, gave me the output I was looking for, I was happy, and went to bed. I'll clean it up later, and let you know if I see anything other than what you mentioned. Thanks for the help though.

I'm well aware that during the process of learning one does not always find the best way at first and is happy to find a way that works anyhow. So my posting was not intended to criticize you. Just wanted to give you some pointers what can be optimized.

Two things are possible.
1 - the .NET framework is broken ( report it to Microsoft )
2 - your code has an error ( we can't tell what the error is without seeing it )
Do you start your timer ? How do you know it doesn't get called, do you set a breakpoint, or are you assuming that because you don't see the end result you hoped for ?

Hi I'm new to programming, currently I'm learning C#.
I am attempting to build an audio app DJ style and using C# and it is proving a challenge.
My questions is should I be using C# for building audio apps or is there a better programming langauge more suited to the task?
Thank you
Mike

That's a ludicrous thing for someone 'new to programming' to attempt. Learn to program first, then worry about libraries like DirectX, or using components like the Windows Media Player control.

C++ is more powerful, but I wrote a video jukebox in C# which is in constant use in clubs and pubs in the country I live in, so there's every reason to expect you can do what you want in C#, if you learn it first.

Hi All,
I m new in Programming with C#.
I have created a method by means of passing the values using the two dimensional array of type int[,].
ie., i am passing two matrix A and Matrix B and calculating the sum and sub for the two matrix A and B. and i m storing it in the Matrix C.
And i am calling this method in the main program everything works fine but it shows the error as
No overload for method 'AddMatrix' takes '0' arguments and the same for the 'SubMatrix' also.
I want to know how to pass the values in the main program.
with regards,
Chitra

How can both these things be true ?
chitra4sat wrote: No overload for method 'AddMatrix' takes '0' arguments and the same for the 'SubMatrix' also.
Then you forgot to pass the parameters
chitra4sat wrote: I want to know how to pass the values in the main program.
Not sure what you mean, but if you have a method
int Add(int a, int b)
{
return a + b;
}
You are doing this:
int n = Add(); // Can't do it, wrong number of parameters
but you need to do this
int n = Add( 1,2);
or this
int x = 1;
int y = 2;
int z = Add(x,y);
Or any combination of the two.
You probably need to post your code if you need to ask any more, so we can see what's going on.

here is my code for your reference:
in the main class
Here i m giving the values for the matrix A & B
int[,] MatrixA ={ { 1, 2 }, { 2, 3 } };
int[,] MatrixB ={ { 3, 4 }, { 4, 5 } };
public int[,] AddMatrix(int[,] MatrixA, int[,] MatrixB)
{
int numberOfRows = MatrixA.Length / 2;
int numberOfCols = numberOfRows;
int[,] MatrixC = new int[numberOfRows, numberOfCols];
for (int i = 0; i <=numberOfRows; i++)
{
for (int j = 0; j <=numberOfCols; j++)
{
MatrixC[i, j] = MatrixA[i, j] + MatrixB[i, j];
}
}
return MatrixC;
}
And i m calling this AddMatrix Method in the main program as
mymatrix.AddMatrix();
in that how sould i have to pass the value
let me know it ASAP.
regards,
Chitra.

Thats what is worng chitra!!
You cant call AddMatrix without parameters since you have defined your method with parameters!!
What you may do is that you have to pass A and B in AddMatrix method
like
AddMatrix(MatrixA, MatrixB);
It would work then. Hopefully!!
Learning is a never ending process of Life.

Hi,
Thanks for ur reply.
But here,i am giving the values of Matrix A and Matrix B . I have used it as int[,] matrix A={{1,2},{2,3}};
and int[,]MatrixB={{2,3}.{3,4}};
which are the values i am sending it in the program itself .
and i m calling it in the main program as mymatrix.AddMatrix();
but i got doubt there only how to pass the values becoz the values are all mentioned above.
i need that mymatrix.AddMatrix(" how the values to be put it here ");
here if i open that method bracket it is asking the value of (int[,]matrix A,int[,]matrix B)
I am getting the problem only in passing the value only .
so please help me by code in passing the value of this line .
waiting for ur reply ASAP.
Regards,
Chitra.

I have a question survey that I need to add branching and skip logic based on how a question is answered. I need for this to be dynamic because a user can setup their own questions and determine the flow of the questions.
Any suggestions or references on how start this? Is this a rule based engine?

Sounds like you need to define a file format where questions are defined, and answers and question flow is marked. XML would be perfect for this.

Maybe use a decision table or tree?
I agree with Christian. XML would be a good tool here.

Hi All,
I am trying to draw a rectangle and then draw a circle within the rectangle. At this point I have the rectangle drawing but the circle. The circle within the rectangle is going to move based on motion of the mouse. I am going to try to take the input of the mouse and make those my X and Y coordinates. If anyone has any experience with either have 2 paint event handlers or with having to update the circle depending on location, it would be great! Any sample code and guidance would be greatly appreciated! See below for event handlers. I am developing use C# and Visual Studio 2005.
<br />
private static void f1_paint(object sender, PaintEventArgs e)<br />
{<br />
Graphics dc = e.Graphics;<br />
Pen p = new Pen(Color.White, 3);<br />
dc.DrawRectangle(p, 478, 10, 487, 352);<br />
p.Dispose();<br />
}<br />
private static void f2_paint(object sender, PaintEventArgs e)<br />
{<br />
Graphics dc = e.Graphics;<br />
Pen o = new Pen(Color.Orange, 5);<br />
dc.DrawEllipse(o, 717, 176, 5, 5);<br />
o.Dispose();<br />
}<br />
<br />
this.Paint += new PaintEventHandler(f2_paint);<br />
Thanks,
Laura

Don't use a timer. Use the MouseEnter, MouseMove and MouseLeave events to trigger the update the control. Those events give you a MouseEventArgs object that contains the coordinates of the mouse pointer. Store the coordinates in member variables so that you can use them in the paint event.
There is no use in having more than one paint event handler for a control. They will just run after each other, so you can just put all the code in the same event handler.
laura1316 wrote: //In timer function will take in mouse input and update circle so need to call f2_paint.
this.Paint += new PaintEventHandler(f2_paint);
That will not call the event handler, it will instead add another event handler to the event. If you do that in a timer event, you soon will have thousands of event handlers in the paint event, each one drawing the same thing on top of the other.
When you need the control to be redrawn, just call the Invalidate method of the control. This will cause a paint event.

Hey, it's okay buddy, I'm one as well.. "just a couple of decades though"
You should be putting this code in your tab closing triggering button (ie. if your closing the tab pages using a button each time, then each one of these buttons should check first if there's still more tab pages on this tab control and close the current one if there's still some, otherwise, the whole application should be put to an end.. you know "Application.Exit()"..
I hope this was useful
