I have an MFC app that is having some weird issues.
When you start the program and don't move window around it works fine. But as soon as you start moving it around, an exception will occur.
Debugging this in VS, I will get a buffer overrun message or some MFC debug assertion. I'm pretty new to MFC, anyone have any ideas where I should look to fix this?

Very close to the error message (or as last resort, you may post it here).
You should be precise to get any help.

Hi,
I am using AfxBeginthread in my application for reading the datas from my hardware via serial ports. after clsoing my GUI, when i try to open once again, am getting error that "exe is running". I have closed my handles related to port in destructor of the class. i suspect the Thread is not closed completely, it occupies the memory, i want to know whats the better way to close or kill the thread.
thanks in advance,
Balaji S

Use a flag that you set from your main thread.
In your second thread, it looks like:
while (bContinue)
{
}
Once the flag is set to false by your main thread, the loop will finish and the thread function will return, terminating nicely the thread. Of course, how to implement this depends a lot of your current design, this is just the basic principle.

Hi,
thanks for your reply.
now am doing by that way, after false condition am using "afxendthread" function. is it recommended to use or coming out from the while loop itself enough to close the thread.
thanks

Never do that. Simply exit the function (but you have to be sure that you exited the function). Never close a thread by calling afxendthread.

Well, just return from the thread routine. Killing a thread is not recommended really...

Hi,
thanks,
but my concern is, whether my thread occupy memory after closing the application. thats whay i used afxendthread function

See here[^]. It doesn't seem to matter if you use AfxEndThread or simply return.

Microsoft Foundation Classes. A very nice wrapper around portions of the Windows API. Two classes of interest are CDatabase and CRecordset.

Actually I'm doing a portable program which can be executed in any windows platform without any installation. Do you have any suggestions for portable database which can be connected to c++?? Currently I'm working on sqlite. But its kind of complicated.
Thank you.

You #include <sqlite3.h> in your code, link with the sqlite library and use the SQLite C++ API[^] to access the database.
|
|
|
|
|
I think she is still blur how to to use the API.. show her a simple connection program plz... i don know about database so i not sure hw to help her.. :P
Thanks

what does a linker error means?? When i include the #include<sqlite3.h> header file alots of linker error messages is appearing..
|
|
|
|
|
That you forgot to link to the required library. It means that the code compiles fine (there are no syntax error in the code) but when the linker tries to assemble everything together, it can't find some specific functions, because you didn't specify the library from which they are coming from.

Look again at this article[^]. The "Working With SQLite" section gives you instructions for how to build an import library (.LIB file) for the SQLite 3 DLL. To use it, add a line like this to your main C++ file:
#pragma comment(lib, "sqlite.lib")
This will cause the linker to look in SQLite.lib for the SQLite functions.
|
|
|
|
|
>> #pragma comment(lib, "sqlite.lib")
Use a MAKE file to direct the linker to search for functions in that particular
library(.lib) is a more portable way I think, since this directive would be unknown with some compilers other than Microsoft's.

Hell, yeah - but given the OP was commenting like "what's a linker", I thought this was the simplest way to get their code to build
I wish all compilers had that directive - makes building so much easier. I love the way Boost uses it, with auto-selection to decide which of 4 or 6 library variants to link with
