When your program does not compile it is because you have errors in your code. The compiler will tell you what those errors are and where they are. You can easily read those for yourself, you do not need us for that.
If you have a specific question about what one of those error messages mean then post the error message and the line of code that it occured on, and maybe we can help you.
Just dumping your code on this message board and saying it does not compile is the lazy man's way of doing things and will get you no where.

I corrected my errors that were displayed but I didn't know if the order (calculations) of my program could be the cause of it not compiling. I am new to this and have been working on it for the past week but I'm not by any means taking the lazy man's route.

I have an application in MFC. I use the MFC Grid Control.
One of the column is type CheckBox, but I don't know how to check
if the cell is checked or not.

There are lots of MFC Grid controls around. Be specific as to which one you are using.

The CGridCellCheck check class has a GetCheck() member that you can call.
BOOL IsCellChecked(CGridCtrl &Grid, int row, int col)
{
BOOL IsChecked = FALSE;
CGridCell *pCell = Grid.GetCell(row, col);
if (pCell != NULL)
{
CGridCellCheck *pCheck = dynamic_cast<CGridCellCheck *>(pCell);
if (pCheck != NULL)
{
IsChecked = pCheck->GetCheck();
}
}
return IsChecked;
}

Hi!
Look at this code:
Graphics graphics(hdc) ;
Image * img ;
img = Image::FromFile("FileName") ;
graphics.DrawImage(img, 0, 0) ;
When I want to show Image in the Client Area The picture is larger than it should be. Why is that ?
I'm trying to load picture which size is 256x256, but when I use DrawImage, the picture that is drawn within the client area is larger(about 30%).
|
|
|
|

The DrawImage function has many overloads. Us the one where you also specify the width of the destination rectangle.
graphics.DrawImage(img, 0, 0, width, height);
You may be right

Thank you very much!
But to be honest, I've found it later on 
I was just unsure why it was like that, as I thought the function gets it's width and height from the Image structure.

Just a little ?, Do u know GDI+ library is very heavy,if you loading general FORMAT like jpeg,gif etc, then you can try your HAND in IPicture Interface, which provide light way to Display picture in your Program!

Removing the CBRS_GRIPPER style from the toolbar should do it.

Hello
I have writen this in C++ (using the compiler Visual C++ 2005 Express Edition). I am now having some trouble with calculations. I want to work out each sample scores variance (which is used in statistics). I have a bunch of scores that hte user inputs and I can work out the average, that is the program will do that part, but when it comes to working variance the answers are wrong. The variance is worked out like this - each score minus the mean, to the power of two (or times by itself), all these scores then have to be divided by the Number of scores that are in the sample. The program cannot calculate this. For example, there are 2 scores, 1st score = 5, 2nd score = 4; it works out the mean (average) okay which is the total of all the scores divided by the number of scores in the sample. It gets very close to figuring the right amount for the variance, but not quiet. Please help me figure out where I've gone wrong. Thank You in advance. Here is my code:
#include <iostream>
using namespace std;
int main(void)
{
float M, N, total, score1, score2, score3, score4, score5, score6, score7, score8, V1, V2, V3, V4, V5, V6, V7, V8, s1, s2, s3, s4, s5, s6, s7, s8, Variance;
cout << "Input the number of people in sample ";
cin >> N;
cout << "input the 1st score ";
cin >> score1;
cout << "input the 2nd score ";
cin >> score2;
cout << "input the 3rd score ";
cin >> score3;
cout << "input the 4th score ";
cin >> score4;
cout << "input the 5th score ";
cin >> score5;
cout << "input the 6th score ";
cin >> score6;
cout << "input the 7th score ";
cin >> score7;
cout << "input the 8th score ";
cin >> score8;
total = score1 + score2 + score3 + score4 + score5 + score6 + score7 + score8;
M = total / N;
cout << "the mean for these scores is: " << M << "\n";
s1 = (float) score1 - M;
V1 = (float) s1 * s1;
s2 = (float) score2 - M;
V2 = (float) s2 * s2;
s3 = (float) score3 - M;
V3 = (float) s3 * s3;
s4 = (float) score4 - M;
V4 = (float) s4 * s4;
s5 = (float) score5 - M;
V5 = (float) s5 * s5;
s6 = (float) score6 - M;
V6 = (float) s6 * s6;
s7 = (float) score7 - M;
V7 = (float) s7 * s7;
s8 = (float) score8 - M;
V8 = (float) s8 * s8;
cout << "the variance for these scores is: " << (float) (V1 + V2 + V3 + V4 + V5 + V6 + V7 + V8) / N << "\n";
return 0;
}

What do you mean by not quite? If what you have is a sample, are you supposed to divide by N and not N - 1?
