Hi,
In my application I am using Active Sync to connect my PC to Mobile(Windows Mobile).I am using CeCreateProcess() function to invoke exe in mobile.I need to abort my application.
For that I have created one button on my dialog.I have added event handler to that.I have added

PostQuitMessage(0);

while running the application If I click on "Abort" button application is not closing at that point.After completion of present running task only application is closing. For example I am executing testcycle.In the middle I need to abort my application.Can anyone help me.

Rekha.

The clue is in the api command's name.

PostQuitMessage (0)

.

It POSTs a WM_QUIT message to the message queue. This is a signal for your message loop to exit.

While you are still in a function, you're not handling messages... so you don't quit.

ie:

void CMyApp:OnSomeButton ()
{
   PostQuitMessage (0);
   Sleep (10000);
}

will take 10 seconds before it even could quit.

Not knowing what you're doing, that's as helpful as I can be at the moment.

Hi,
In my Application I am connecting to Mobile and sending data to Mobile from my computer using socket.And I am receiving information from Mobile.
If I click on Abort button I need to stop Application.I am using MFC.

Can I use PostQuitMessage(0) for this?

YES.

Now go and read my message again - it won't stop straight away. If you do many other things after the PostQuitMessage command, it will do them first.

exit[^] instead of PostQuitMessage?

it seems to dialog based application, why don't your try EndDialog() api!

i define my own reserved keyword like"_if,_while" and some operations

like "move","opendialogue" and some complex operations"<=","=="

and now i want to make a compiler to analyse "myself language"

That's what source code is for...

Beyond that, I have no idea what you're asking.

Before writing code, you need to have a clear idea yourself what you want the computer to do for you. You need to be able to do the work yourself with pen and paper, then convert that to computer code.

Good luck,

Iain.

I don't mind - I was just having trouble working out how to help you.

Why are you writing code in a txt file? You are posting in a C/C++ forum, so what's wrong with writing C code?

If you are meaning some sort of script you can change anytime, then look at different technology, like (old timers shout "hey!") bat files, or the new windows scripting host scripts.

I haven't played with the new scripting very much though.

As CPallini said, maybe you should buy a book on C, and start reading. Hopefully it will make some sense - even if it only helps you ask more solid questions.

Good luck with your journey,

Iain.

C++ is not a scripting language, so you can't compile things on the fly. You could however write your own 'scripting' language but if you need something a bit evolved, that would be a crazy solution. Why don't you instead integrate an existing scripting language into your application ? Take a look at LUA[^] for instance.

I guess that's what you are looking for but your question is not very clear. So if that's not waht you are looking for, rephrase your question so that it is a bit more understandable.

What are you trying to do?
Do you want to use your file as input for the C++ compiler?
If the answer is yes then you've to follow some rules, i.e. read a good C/C++ tutorial and try again.

Do you want instead to write your own compiler/ interpreter?
Then you should really read some good book about.

Do you want just to write a script?
Then have a look, for instance, at JScript or VBScript documentation.

Compiler and interpreter belong to two different worlds. So, your first task would be to read up and understand how they both work and decide on choosing to create either a compiler or an interpreter.

Somehow I see this is an ambitious project for you, but goodluck nevertheless.
