How can both these things be true ?

Then you forgot to pass the parameters

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!!

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

Hi,
I'm trying to hide the console window of a process that I start from my app.
I'm using FindWindow like this:
[DllImport("user32.dll")]
public static extern int FindWindow(string szClass, string szTitle);
but calls to
int win = FindWindow(MyConsoleAppClass, null);
or
int win = FindWindow(null, "MyConsoleApp.exe");
return 0.
Any ideas as to what am I doing wrong?
thanx
|
|
|
|
|
I think this will help:
If szClass is NULL FindWindow will search for the window by the szTitle (window's title) only. This is useful if the class of a particular window is variable.

Is there a way to remove the files click once places into the project? I am not going to use this feature and would like to remove the files (.pfx, .manifest) safely if I can or should I be concerned? Thanks!

What is in your project is irrelevant, you don't deploy the project anyhow, right ?

I'm working on a program that compares lines from two .txt files line by line.
It compares the first line of the first file then first line of the second file and so on.
But when the two files have different number of lines the program will fall.
How to solve this problem.
C#
|
|
|
|
|
You can simply do it by checking the line you get first from the stream before comparing it with what so ever, sorry but not sure how to do it in c#, however you have to look for the "end of file" escape character, we use EOF in c++..
while(youStreamReader.ReadLine() != EOF)
dadadadada...
Another alternative is that you can read the entire file contents once before starting the comparison process and determine the number of lines "using the end of line escape character which you have to find out " and use this number in your loop to break it later.. hope this was of some help.

When two lines do not match, you need to search ahead in both files, to see if either file has a line ahead that matches ( or better matches ) the current one. A brute force approach here is going to be very expensive, I would think.
