Thanks for all the responses. After looking at the alternatives, I came to the conclusion that just putting out plain text using TextOut was the way to go.

The program is to keep records and perform statistical for a class of students.
the class may have up to 40 students. They have 5 quizzes, and all the students are identified by a 4 digit student number
and the program will print the students scores and calculate and print the statistics for each quiz
Student Quiz 1 Quiz 2 Quiz 3 Quiz 4 Quiz 5
1234 78 83 87 91 86
2134 67 77 84 82 79
3124 77 89 93 87 71
High Score 78 89 93 91 86
Low Score 67 77 84 82 71
Average 73.4 83.0 88.2 86.6 78.6
but this is what i have so far
#include<stdio.h>
#define ROW 4
#define COLS 5
int main(void)
{
// Local Declarations
int table [ROW] [COLS] =
{
{1234,52,7,100,78,34}'
{2134,90,36,90,77,30},
{3124,100,45,20,90,70},
{4532,11,17,81,32,77}
};
int line [ROW * COLS];
// Statments
for (int row = 0; row <ROWS;row++)
for (int column =0; column < cols, column++)
line[row * cols + column] = table [row] [column];
for (int row = 0; row <ROWS * cols; row++)
printf("%02d", line [row]);
return 0;
} // main
When i execute im getting 42 errors

Hey folks!
Got 2 minor questions i thought i ask here maybe you know an answer to.
First: do you know about any way to check if a given hotkey is available on the system or not? I'm talking about hotkeys you can register using RegisterHotKey[^]. I know this method will fail if the key specified is already registered by someone but if it is not it WILL register the key, but i would like a way to check if i could register it WITHOUT actually doing it (that would happen later on). I know one way would be to try and register it and if it succeeds unregister it again right away but this solution doesn't sound so nice.
Second: I'd like to have a window staying above all other windows that belong to the same process, so it is kind of an always-on-top window but not a system-wide always-on-top window, i do not want this window to stay above all the other windows on the system that belong to different processes.
Thanks in advance for any suggestions.

From the documentation you linked to:
RegisterHotKey fails if the keystrokes specified for the hot key have already been registered by another hot key.

Thanks for the answer. As i said, i am aware that RegisterHotKey will fail in case the hotkey is already used BUT at the point i want to check if it is available i do not wish to actually register it.

Yes you did. My fault, I read your post the first time and missed that part. Unfortunately there might not be another way to do it.

Oh well, i'll go with what i can get, i was just hoping for a more sophisticated way to do it. Thanks.

Thanks, i will check if i can use any of that, the project is not an MDI app but an SDI one with a few floating windows and i want one modeless dialog to stay above all the floats.

Then you probably want to check out the SetWindowPos flag WS_EX_TOPMOST
|
|
|
|
|
The problem with WS_EX_TOPMOST is that it will make the window "globally" always on top, menaing it will cover all non-always-on-top windows on the system but i only want it to cover the windows of itw own process.

Hi every one.
I have used 'NTGraph3D.dll' from [3D Graph ActiveX Control] with out any problem,
But When I want to compile the source using Visula Studio 2008 SP1 the below error occurred!
GraphCtl.obj : error LNK2019: unresolved external symbol "char * __stdcall _com_util::ConvertBSTRToString(wchar_t *)" (?ConvertBSTRToString@_com_util@@YGPADPA_W@Z) referenced in function "public: void __thiscall CGraphCtl::DrawAxisLabels(struct HDC__ *)" (?DrawAxisLabels@CGraphCtl@@QAEXPAUHDC__@@@Z)
.\Debug/NTGraph3D.dll : fatal error LNK1120: 1 unresolved externals
any one could help??
or how could I use the source of this control in my program
instead of ActiveX control prepared by the source.[thanks]

Only I know that this function in its last 7 lines cause the error, if you cuold recognize it please tell me.
void CGraphCtl::DrawAxisLabels(HDC hdc)
{
float X,Y,Z,res;
int i;
char str[50];
CPoint3D pt;
COLORREF colX, colY, colZ;
OleTranslateColor(m_clrXGridColor, m_hPal, &colX);
OleTranslateColor(m_clrYGridColor, m_hPal, &colY);
OleTranslateColor(m_clrZGridColor, m_hPal, &colZ);
res = (dRangeX[MAX] - dRangeX[MIN]) / m_nGridX ;
for ( i = 0 ; i <= m_nGridX ; i++)
{
X = dRangeX[MIN] + (res * (float)i);
sprintf(str,"%g",X);
X = ((float)i)/m_nGridX;
SetColor(colX);
pt=CPoint3D(-0.5,-0.5,0.5);
pt.Translate(X,0.0,0.3);
PrintText(hdc, pt, str);
}
res = (dRangeY[MAX] - dRangeY[MIN]) / m_nGridY ;
for ( i = 0 ; i <= m_nGridY ; i++)
{
Y = dRangeY[MIN] + (res * (float)i) ;
sprintf(str,"%g",Y);
Y = ((float)i)/m_nGridY;
SetColor(colY);
pt = CPoint3D(-0.5,-0.5,0.5);
pt.Translate(0.0,Y,0.3);
PrintText(hdc, pt, str);
}
res = (dRangeZ[MAX] - dRangeZ[MIN]) / m_nGridZ ;
for ( i = 0 ; i <= m_nGridZ ; i++)
{
Z = dRangeZ[MIN] + (res * (float)i) ;
sprintf(str,"%g",Z);
Z = ((float)i)/m_nGridZ;
SetColor(colZ);
pt = CPoint3D(0.5,-0.5,-0.5);
pt.Translate (0.2,0.0,Z);
PrintText(hdc, pt, str);
}
SetColor(RGB(0,0,0));
using namespace _com_util;
SetColor(colX);
PrintText(hdc,CPoint3D(0.0f,0.7f,-0.5f),ConvertBSTRToString(m_bstrXLabel));
SetColor(colY);
PrintText(hdc,CPoint3D(0.7f,0.0f,-0.5f),ConvertBSTRToString(m_bstrYLabel));
SetColor(colZ);

glEnd();
}

Are you linking with the correct library? Have you seen this and this and this?

Thanks David The Solutions was totally nice especially the last one.
I have corrected the problem by adding the lines below (using your solutions):
#ifdef _DEBUG
# pragma comment(lib, "comsuppwd.lib")
#else
# pragma comment(lib, "comsuppw.lib")
#endif
# pragma comment(lib, "wbemuuid.lib")
By the way, now the program works fine for making ActiveX Control , Do you have any idea How to
change it to use in my program directly.

Hi, does anyone know how to make the crossover in a real-coded genetic algorithm? If so, can you explain this to me, thanks!
|

Hello,
There is a Genetic Algorithm Library[^] at CP that you may want to take a look at.

Thanks for the reply. What I've seen in the library tutorial about crossing real-coded chromosomes is that one makes the mean value between the values of the geans, is this so?
|
|
|
|

Well, I am not a genetic algorithm expert, neither do I feel like reading through that article.
But, you may very well start a new thread at discusion board at the bottom of the said article, which will have a higher chance of being replied to.
