hey guys, ive got a dialog based MFC application im working on. Class Cdraw controls hardware through the serial port, that has to perform X number of tasks in time Y.The program will only finish once all tasks have been completed, so i wanted to make some sort of a manual override button to stop the program (kill the loop) and return control to the dialog window. I believe threads are the best way to do this. I've never used threads before and i dont know how to work them. Does anyone have suggestions to a quick solution, like an easy threads tutorial? I'd like to see example code/projects too.
All i need to do is a user-interface thread to watch one button, and stop everything when it is pressed.
Cheers,
Ayush

Thank you so much!
I assumed user-interface threads dealt with that thing. But i was wrong. That articel is superb.
Cheers!

How can I get the height of a toolbar and a statusbar?
I am using MFC with the standard CToolBar and CStatusBar classes.
I see functions to set the height, but nothing to get it...
|
|
|
|
|
Try m_wndToolBar.GetWindowRect(...) and get rectangle height. The same for status bar.
|
|
|
|
|
No go.
Returns a rect with 0 height and width
|
|
|
|
|
Actually GetWindowRect should work. Did you ensure that the toolbar is both created and added to your application when calling that function?
One thing I remember is that possibly the function could return 0 when called on docked toolbars. In that case you could try to calculate its size with the help of window - and client-rect of your view. But I'm not sure at all

Hi, Could anyone describe a simple algorithmn for the perceptron learning rule?
For example, lets make it simple :
a) Number of CARS on a road.
b) The TIME of the day.
well, how is it possible for the algorithm to determine, after learning the pattern of amount of traffic or it means the number of cars on that particular road at the particular time, whether it is a small traffic, or it is a average traffic or it is a high traffic situation.
Well, I do understand, that what the perceptron is doing but how will that algorithmn for the perceptron help to determine, and learn and understand, when it is normally at the time of the day for the traffic is high, or low or average?
Could anyone help? I mean how does the algorithmn do it i don't get it,

Dear friends, i obtained certain code written in VC++ from some web site. The site also mentioned instructions to build the source code. I am unable to understand the following instruction:
Make sure these directories are in your PATH environment variable:
C:\MyLib\Lib
C:\MyLib\functional\Lib
Plese tell me what is the PATH variable and how can i follow the above instruction in VC++6 or 7
|
|
|
|
|
To display the PATH environment variable:
echo %path%
To add a path to the variable:
SET PATH=%PATH%;?newpath?
?newpath? stands for the path you want to add, for example C:\MyLib\Lib.
Remove the ?.

Still didn't understand  where we have to do this ?? At command prompt ?? But i am currently in VC++ IDE and on compilation i got errors that path variable not found

In a Win9x environment, you can set the PATH variable through the autoexec.bat ('SET PATH=whatever', as detailed in the above post). In NT (and I suspect XP/2000, but I cant remember at the moment), from the Control Panel go to 'System', and then 'Environment'. From there you can change/add the PATH environment variable.

PATH is an environment variable. If you don't (yet) know what an environment variable is, you should probably study some documentation.
There are several ways to set an environment variable, but for this particular case I believe it would be easist to:
- Open a command console window.
- Type "set PATH=%PATH%;C:\MyLib\Lib;C:\MyLib\functional\Lib" followed by return (or enter if you like).
- Start MSDev from this same command console, so that it inherits this process' environment variables, including PATH. What this executable is, is probably depending on version of MSVC, but for v.6 it's msdev.exe.

Hi :
I created a very simple dialog in a DLL. This dialog has only the OK, CANCEL , and a static text.
In my application, I create an instance of this dialog, for example :
#include <dlldialog.h>
....
CDLLDialog d ;
d.DoModal() ;
....
This will bring up the dialog. However, the dialog remains greyed out and does not response to mouse or keyboard.
Can somebody offer me advice on what I need to do, or at least point me in the right direction ?
Thanks.

Call DoModal from the Dll itself:
void CSomeClass::ShowDlalog(CWnd* pParent) // exported class
{
AFX_MANAGE_STATE(AfxGetStaticModuleState( ));
CDLLDialog d(pParewnt);
d.DoModal() ;
}
and call this function from client.

Hi :
It works after all.
I was creating the extension DLL which will give the compilation errors. A regular DLL wouldn't.
