Hey all im making a game for school on MFC and im having trouble making it so when I press W,A,S, or D it will move my character... I know how to make him move if I press the arrow keys (previous game):
case VK_DOWN: //IF DOWN BUTTON IS PUSHED
{
}
I have already tried VK_A, any help would be appreciated!
Thanks

I think you need this
case VK_DOWN:
case 'S':;)<br />
{<br />
...<br />
break;<br />
}<br />
<br />
case VK_UP:
case 'W':;)<br />
{<br />
...<br />
break;<br />
}<br />
<br />

I need to convert an unsigned int to a char*.How can I do it??
Thanks in advance!!

#include <stdlib.h>
#include <stdio.h>
void main()
{
unsigned int i = 123;
char p[100];
itoa(i, p, 10);
printf("%s\n", p);
}

alan top :
<br />
void main()<br />
{<br />
unsigned int i = 123;<br />
char p[100];<br />
<br />
itoa(i, p, 10);<br />
printf("%s\n", p);<br />
}<br />
-----------and-----------------
unsigned int a=100;
char *buffer;
buffer=(char*)LocalAlloc(LPTR,20);
itoa(a,buffer,10);
unsigned int c;
c=atoi(buffer);
LocalFree(buffer);

Here is another way to do this
unsigned int i=100;
char p[10];
sprintf(p,"%u",i);
cout<<p;
Knock out 'T' from CAN'T ,
You 'CAN' if you think you 'CAN'

You can Also use Reinterpret_cast
Thanks & Regards

I create a client socket class that derived from CAsyncSocket, it connects to server ok. When server disconnects then nothing wrong, but when client side closed the connection then it's got a problem: sockcore line 482 (and 442), those lines are:
ASSERT(CAsyncSocket::LookupHandle(hSocket, bDead) != NULL);(line 482)
ASSERT(CAsyncSocket::LookupHandle(hSocket, bDead) != NULL);(line 442)
Can any one tell me why it happen and how to handle it?
Just a newbie

When one side of a socket connection is closed the remote stack is notified and the state of the socket handle is updated. So "if" the other side calls close the handle is not in a valid state to be closed.

That is up to you to determine based on the applications use model. One option is to use AsyncSelect[^] to be notified when the other socket closes the connection.

It's not really close to my problem. In my situation, after client successfully connect to server, call Close() function will make the program crash. It's strange because it doesn't happen in server side and in other example i saw.
If problem is remote stack then when client close, the side that encounter problem is server side right??

Sorry. I misunderstood the first post.
It does seem however that your client side socket is not in a connected state when you are trying to close it. Or the MFC Thread Local Storage does not contain information for that Socket. That is why the assert is firing. Based on what you posted there is no way to determine why. That assert is letting you know that the MFC collection of opened or in their language, "Not Dead", sockets does not contain the socket handle you are attempting to close.

I wrote some code using Visual Studio.net with MFC and it is easy to add stuff to the dialog box. But, I can't remove anything like an edit box etc. when there was an associated var name in the code. I get run time errors or if bad enough, I get severe compile errors. I tried doing it with just one litle window and I get runtime errors. How in the world do you remove something you do not want anymore. I removed everything that was associated with it I thought. When I removed from the resource.h file, thank god I had backed it up. I had to abort and reload the original code, it was so screwed up.
Help would be greatly appreciated.

By selecting the text in the code, and [DELETE].
dzldan wrote: I get run time errors
This is because you only deleted the control(s) on the dialog editor, but not the C++ code in the source.
Checklist:
1) To delete the data members in the class definition.
2) To delete some related DDX_ ... in the implementation of DoDataExchange(). <-- Runtime error usually happens in this function.
3) To delete some related message handlers which you created by double-clicking on the controls on the dialog editor.
4) ...

Each compilation error message stands for its meaning. Check those listed above.

Thanks for responding so quickly. I guess the problem really is that running in release dir is ok, but running in debug if I take things out causes debug assertion errors. Any idea how to get rid of that. I did a clean and rebuild but I get this winocc.cpp line 247 error.

Not "get rid of that" but check your code by debugging to find out what happened before "WinOcc.cpp" line 247 had been executed.

No idea which guy voted my reply down  , but:
1) The information from the original post wan't too much. He did not quote the last line in his code (not "winocc.cpp") before the fired assertion.
Let's assume he hasn't know what the action 'debugging' is.
2) Once an assertion is fired, VC++ prompts for [Debug], [Continue], or [Abort]. Then the original poster should click that [Debug] button to back-trace the cause when he has read that bold words "debugging" and "before" in my previous reply.

Hello
Did you know any graphic library (with C++ support) including some functions/methods which allow you to grab a single/multiple frame/frames from vide movie (avi or mpeg for ex.) and then save it as a bitpam or jpeg image??
Did you know any graphic library (with C++ support) including some functions/methods which allow you doing some operations & transofmations on images (bitmaps for ex.) like filtering of motion detection???
I'have heard that such funcions do exist for ex. directly in MS DirectX librarys (components) but i i hardly know abot it.

see MS's DirectShow for frame capture.
there are dozens of graphics libraries out there that can do transformations and filtering (for example, see the one at the bottom of my post - or see the ones available on CodeProject)

code
//---------------------
class One
{
public:
int i0;
};
class Four
{
public:
One ones[4];
int iNum;
};
Four four;
One & o = four[0];
//---------------------
last line above is an error.
I think the error can be solved by define a suitable operator in class Four.
any idea?
