That's illegal. I assume you somewhere have declared a pointer to the CMain class in your CComp class: CMain *pParent. For example declare in your header file: CMain *pParent and initialize it from your main class: CComp dlg; dlg.pParent = this;.
Then use this: pParent->uc_top = m_uc_ts.GetCurSel();.
Hope that helps

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

Sounds like you have failed to add a closing brace for a function preceeding this one in the same file.
void CComp::SomeFunction()
{
void CComp::OnSelchangeLUCOMPTop()
{
UpdateData(TRUE);
Tselection1 = "Selection Changed";
CMain::uc_top = m_uc_ts.GetCurSel();
m_uc_epo.EnableWindow(TRUE);
m_uc_epp.EnableWindow(TRUE);
}

Are you BitBlt the bitmap to the window DC? Probably you do so, and when you do so it will disappear when you repaint the client area which happen when you resize the window.
You'll need to paint the bitmap in your WM_PAINT handler.

Guys,
I've a dialog based application which is a very large size application and i am working on it for about 8 months.
For the last two days i am having a trouble. The problem is that on my machine i compile it using Visual C++ 6.0 compiler and when i run the debug version, it runs normally.
Now if i take the debug exe to other machine and run it, i get the following system error:
The instruction at 0x00000000 referenced memory at 0x00000000. the memory could not be read.
Strange if i compile the program on second machine and run it, it works normally. But if i transfer the same exe to first machine, i get the same error.
For some testing i compile program on first machine and try to run the application in debugger of second machine. I placed a break point in the InitInstance() of Application class. But it is crashing before the control enters the InitInstance(). Can anyone tell me how to solve the problem.
Oh yes one more thing. In my workspace there are five projects. Four of them are statically linked with MFC and use Debug Multithreaded dll confguration. While one is not using MFC. I am just using debug builds.

Hi,
This crash is happening because of different versions of MFC runtime libraries u r using in debug mode. U can find this by using dependency walker.
To resolve the problem u r facing
1. Create setup which will port all dependencies of ur application to other machine.(not a good option)
2. As u have mentioned, Four of them are statically linked with MFC and use Debug Multithreaded dll confguration, use "debug Multithreaded" option.
This will solve ur problem.

Hi all,
I want to draw sound wave but I don't know how to get the sound data. For example, I have a sound which length is 100 frames and I want to get the sound data at each frame.
Thanks in advance,

Could someone pleae explain the following typedef?
I know that I_TextOutput is an abstract interface and
that GETPLUGIN is a function that will be loaded from a dll.
typedef void (*GETPLUGIN)(I_TextOuput**);
Thanks,
Steve

Ok, I follow that much. But take for instance this typedef
typedef float balance;
Here your are telling the compiler that balance is another name for float.
But in the case of the above mentioned typedef
typedef void (*GETPLUGIN)(I_TextOutput**);
Is void being defined as (*GETPLUGIN)(I_TextOutput**)?
What I don't understand is the makeup of the typedef itself.
Thanks,
Steve

Okay that makes more sense. As you said it is bizarre.

I'm using the old style of c++(console) and would like to know if there are some ingenius people out there and would like to find out how can a game of tic-tac-toe be artificially intelligent. How would I make the computer check anything. Please do help! little person.
#include <iostream>
using namespace std;
char array [3] [3]; //Tic Tac Toe array
char check();
void init_array();
void get_player_move();
void get_computer_move();
void disp_array();
int main()
{
char done = ' ';
init_array();
do{
disp_array();
get_player_move();
done = check(); //See if any winner
if(done != ' ') break; //Winner!!!
get_computer_move();
done = check(); //See if any winner again
system("cls");
} while(done == ' ');
disp_array(); //Display final array
if(done=='X')
cout << "You won!\n";
cout << "Programmed by:\n Tom Dziedzic \n";
if(done=='O')
cout << "I won!\n";
cout << "Programmed by:\n Tom Dziedzic \n";
return 0;
}
//Initialize the array
void init_array()
{
int i, j;
for(i=0; i<3; i++)
for(j=0; j<3; j++) array[i][j] = ' ';
}
//Get the player's move
void get_player_move()
{
int x, y;
cout << "Enter X,Y coordinates for your move: ";
cin >> x;
cin >> y;
x--; y--;
if(array[x][y]!= ' '){
cout << "Invalid move, try again.\n";
get_player_move();
}
else array[x][y] = 'X';
}
//Get a move from the computer
void get_computer_move()
{
if(array[1][1] == ' ')
{
array[1][1] = 'O';
goto e;
}
else if((array[0][0] == ' ' || array[0][0] == 'O') && (array[0][1] == ' ' || array[0][1] == 'O') && (array[0][2] == ' ' || array[0][2] == 'O'))
{
array[0][2] = 'O';
goto e;
}
e: ;
}
//Display the array
void disp_array()
{
int t;
for(t=0; t<3; t++) {
cout << array[t][0] << " | " << array[t][1] << " | " << array[t][2];
if(t != 2)
cout << "\n---|---|---\n";
}
cout << "\n";
}
//See if any winner
char check()
{
int i;
for(i=0; i<3; i++) /* check rows */
if(array[i][0]==array[i][1] && array[i][0]==array[i][2])
return array[i][0];
for(i=0; i<3; i++) /* check columns */
if(array[0][i]==array[1][i] && array[0][i]==array[2][i])
return array[0][i];
//Test diagonals for winner
if(array[0][0]==array[1][1] && array[1][1]==array[2][2])
return array[0][0];
if(array[0][2]==array[1][1] && array[1][1]==array[2][0])
return array[0][2];
return ' ';
}

I'm assuming that what you want is the computer to play tic tac toe against a human, with the human being the x's. I'm not into A.I, but you can do this by brute force, since it's only tic tac toe with so many possible combinations. There are eight ways that the computer can win, and 8 ways that a human can win, for a total of sixteen winning combinations (3 vertical rows, 3 horizontal rows, and the two diagnols for each of the players). When it is the computer's turn, check all of the combinations for a win. If there is not immediate win, then check all of the human's combinations for a win and block it. Your check() function would have to be modified. What I would do, say for checking the computer for a win, is count the number of o's per combination, with the only possible counts being 0, 1, or 2. Save the combinations that don't have x's. This will be used for the computer's move, once it's determined that the human doesn't have a pending win forcing the computer to block. Now check all the combinations again, this time for x's to see if the human has a pending win that the computer must block. If there were 2 x's in a combination with a blank, then the computer would have to put an o in the blank to block the human's win. If the player didn't have a pending win, then go back to the saved combinations for the computer and programatically determine the best move, based on the counts in the combinations of o's. This is brute force, but with careful maniupulation, this would get the computer playing a human.

I have a dialog based application - the dialog being a derivitave of CDialog.
The dialog does not have a title bar. I can customize the icon shown in the taskbar when I run the application, but I have no idea how to change the text on the taskbar.
When I enable the title bar, the taskbar shows the text that I enter in the caption field in properties. When I disable the title bar, and delete the caption, the text of course disappears from the taskbar. If I enable it, enter text in the caption, and disable it, my dialog acts pretty funky and the taskbar text does not appear.

You can use the SetWindowText(...) function in your InitDialog.

I know that VS.Net have included the Crystal Report. And I do know that
it is third-party software. The company is now releasing Crystal Report
version 9, so I wonder what kind of Crystal Report have we got in the
VS.Net? Is it a full version or simplified version? or even worse, a
trial version?

It's starting to tick me off here! I have this template class (may or may not be relevant), and my code seems to crash somtimes. Thing is I can't see much more than just a vague pattern, and it seems to move around a lot. I think it's somthing to do with the heap... When I first tested the code, it somhow crashed within a _tcsdup command, somwhere within the allocation part. So as I havn't used this command too much in the past I just replaced it with
LPTSTR mystr = new TCHAR[_tcslen(str)+1];
_tcscpy(mystr, str); That seemed to move the problem somewhere else:
newbuckets = new Bucket[newarraysize]; Bucket is a nested struct in my class. And newarraysize is sensible value around 11ish. Stepping inside stack scope, I came to a place in malloc.c (ln 211) right before things descend into assembler of ntdll.dll.
return HeapAlloc(_crtheap, 0, size); Baffling because _crtheap seemed to have a value of 0x00320000 (or somthing), and size was not dissimilar to what I'd requested up above. Ok; then somthing triggered the problem to move elsewhere onto a memset function of mine; used to initialise this array of buckets with zeros. That was crashing on in some kind of inline assembly loop routine. So I replaced the memset command with a ZeroMemory, and that caused the problem to descend back on my string allocation routine above!  Has anyone seen this before? any ideas? any at all?

Make 1000058108829489190289840 calls to _CrtCheckMemory all through your code. It is an ugly hack, but the most effective way I have seen, other than the use of specialized tools, to handle this problem.

I'm going to patent thought. I have yet to see any prior art.

Yes I was beginning to wonder about the validity of the memory myself, but I even have a try block around the bucket allocation, and which survives ok! It's almost like the system's giving me bogus allocations!
