Does this imply that you are working on an SDI or MDI application?

Neither actually, it's a dialog based program because there's only a couple things the user can do.

So is CFileDialog what you are looking for then?

The documentation for WritePrivateProfileString() clearly states that if the lpKeyName parameter is NULL, the entire section, including all entries within the section, is deleted.

Hi all!
I have a thread problem in the following code:
(This is not the complete code..)
Somewhere in a function i have the following implementation:
/*****************************************/
// Start of thread
HANDLE hThread = CreateThread(...);
// Wait until thread ends
WaitForSingleObject(hThread, INFINITE);
...
/*****************************************/
// Thread procedure
DWORD WINAPI ThreadProc(LPVOID lpParam)
{
// My code
......
......
SendMessage() <--- The system right here is deadlock (***)
return 0;
}
(***)
The SendMessage() function sends message (LVM_INSERTITEM) to a list view control of the window that stared the thread.
The problem is that I want the SendMessage() function to work, without removing the WaitForSingleObject() function, or any other "wait" function it might need to be replaced.
Thanks for any reply!

This will never work !! I suppose the function which creates the Thread is not in another thread than your application ? Thus your application will freeze because of the WaitForSingleObject call. And because of that, it cannot process messages anymore (so it will not respond to user events neither).
It is not a good idea to call WaitForSingleObject in the main thread. A better idea would be that, when your secondary thread finishes, it sends a message (an owner defined message) to the main window resulting in calling a specific function that will manage every that needs to be done when your thread finishes.

Hello,
What you are doing is asking for trouble! The rule of thumb is: never touch the GUI from your worker thread!!!!
If you really need to do this, try the following: use PostMessage() instead of SendMessage().
If you really need to wait for the thread to finish, use MsgWaitForMultipleObjects() instead of WaitForSingleObject(). This way, your app won't freeze because it will process messages.
Hope this helps.

how to develop an assembler in C++
the idea that i got was
__asm {
}
but do anyone have any idea more abt that?

 This sentence means nothing ! For me, assembler is a low-level language. So, how can you 'develop' a language ??
Otherwise, yes with __asm you will be able to use write assembler code inside your C++ code. But that does not mean you are developping an assembler.

yes but you well need an interpreter or a compiler for your language to work...
i think it is what this guy is talking about with bad-used words...

This is not true, an assembler is a program that translates assembly language into machine code.

Hi and thanks in advance,
I have implemented a DLL language system for my app, but I can’t open the dialogs with a DLL language loaded if this contents any custom control. When I do the dialog.DoModal (); it returns some error (I think it is caused by some template), the dialog don’t appear and the execution continues. If I try to open the same dialog without have loaded any DLL or if the dialog doesn’t contents anyone custom control, the system runs properly. I don’t know what can I do.
Your help will be appreciate, thank you very much.

I have to develop an assembler based on the below processor description :
M05 is a new generation processor from Lintel Technologies. It is a simple 16 bit
multipurpose processor targeted for consumer electronic devices .It has a 16 bit accumulator
A , 16 bit flag register , a 16 bit data register D and a 16 bit memory pointer register P .
It also has a 16 bit Program Counter register PC and a Stack pointer SP.
It supports the following instructions .
* Move immediate data to A,D,P and SP
* Move data pointed by P register to A or D
* Perform arithmetic operation on A register with D register( add ,sub , adc , sbb ,xor
,or ,etc)
* Move data in A register to memory pointed by P
* Call subroutine and return
* Unconditional and conditional jump ( ie jump or carry etc)
* Jump to or call to address pointed by A
The registers A and D can be accessed as 8 bit units ( AH ,AL , DH , DL)
List down the set of all possible instructions and assign your own opcodes. Your assembler
should accept decimal and hexadecimal data . HExadecimal numbers start with a '0' prefix and
terminate with a literal 'H' - for example 0FFEFH . Any text that follows ";" in the same
line should be treated as a comment . Assure that the assembler is case insensitive.
