Re: A question about the precompiled directive ASSERT

Never heard of it. There is the _ASSERT() macro.. but i guess this ASSERT must have been defined somewhere else in your code, since obviously the one who wrote the code tried to run his own Debug Tracer.

Thanks, Rage pal!

I am not agree with you. Smile | :)

I think I can use "ASSERT (a>0);"
directly in MFC(without #define ASSERT before), so I think the
precompiled directive ASSERT is defined somewhere in the
compiling system and not in my app. But I am not sure about it.

Maybe ASSERT is defined only in MFC and it is not C++ stardard.
I am not sure.

What is your opinion?

Cheers,
George

Yup, you're right. I tried

#ifdef ASSERT
g
#endif

and it raised a compilation error (in a MFC project of mine). Sorry. Blush | :O

For sure. Assertion are not C++ standard. check out <assert.h>

BTW, where are you from ? I mean, originally (know your current location are US, but George seems to me like a french name)

Thanks, Rage pal!

I am from Mars. My uncle is Martin. Smile | :)

I have another question, where can I find the
table of all the C++ standard compiler predefined
directive and their related meaning, like __LINE__?

Thanks in advance,

Check out the MSDN (online on www.msdn.microsoft.com[^])
i.e. make a search of __LINE__ for macros or simply #pragma or #ifdef for directives. I can't link you the right page, since i have no internet access but a few sites (like CP) Frown | :(

. I could copy and paste it here, but that's not really interesting since my local MSDN is in german Unsure | :~

Thanks, Jörgen.

Is _DEBUG a windows pre-defined precompile directive
or C/C++ standard pre-defined precompile directive?

Thanks in advance,
George

It's defined by the project files I believe. When you chose a debug configuration, the compiler is passed "/D_DEBUG" IIRC.

This is however not the standard way. The standard way is to define NDEBUG (not debug) in release builds. So if you want to be cross platform, you should write code like:

#ifndef NDEBUG
// debug code here
#endif

Also, if NDEBUG isn't defined, then the macro assert is defined (if you include assert.h that is). But I am unsure if VC++/VS.NET defines NDEBUG in release builds or not.

Hi,

Can u help in any way for following query ????????

How can I copy user I/O (eg creating,modifing,reading a file or folder)to a fixed hidden directory ?
So that all orignial file/folder are copied to the hidden directory
When the computer is rebooted,origninal files/folder redirected back to the their location and should override the modified files/folders.

Hoping for a positive response .

Mouse shortcuts

Hi all,

I'd like to write an app which enables mouse shortcuts for not only one specifical app, but for all the apps currently running under windows (i.e. Minimize a window, Switch to next window (like Alt+Tab), ...).
1. Is this really useful ?
2. How would I implement such a thing ? It would require to catch mouse events befors they are dispatchded to the top lying window. Is this possible ?

What do you mean when you say mouse shortcuts? My mouse has maximum 3 buttons, and I don't know which of them could bear being responsible for shortcuts Smile | :)

Uh ... one thing that occurs to me is installing a hook (SetWindowsHookEx) of type WH_MOUSE. That could solve your problem when placed in a DLL thus having Windows-wide scope.

What is the function of __FILE__ and __LINE__?

Ever run Mozilla ? If yes, you should know what I mean. Mouse shortcuts are working this way : Hold a button down and draw a simple figure (a vertical line, an horizontal line, a right angle, etc..) then release the button. What you have drawn is detected, and is associated to a command. For instance, if i push right button, then go right, then down, then release it, it would minimize the current top-level window. A drawback is, this must not interfer with the right click possibility of the app associated to the window (for instance if drag and drop is enabled).

Cool .. I was just crawling into MSDN, and found these Hook functions also .. this must be the possibility.

IAS

Hi
I have a problem in a programming project with Visual C++
It is an extension dll for IAS (Internet Authentication Service) to
accounting and authentication dial-in users, this is a program for
using in ISPs (Internet Service Providers). IAS supports the
RADIUS (Remote Authentication Dial-In User Service) protocol.

But my problem:
In the RadiusExtensionProcessEx function when I reject the user
{
*pfAction = raReject;
}
I can add some attributes to the authentication response
{
(*pOutAttrs)[0].dwAttrType = ratReplyMessage; //=18
(*pOutAttrs)[0].fDataType = rdtString;
(*pOutAttrs)[0].cbDataLength = 24;
(*pOutAttrs)[0].lpValue = "Testing Reply Message...";
(*pOutAttrs)[1].dwAttrType = ratMinimum;
}
This specifies a message to display to the user, But if the user
is dialing form windows OS, so this message don't show to he and
windows request from the user to check and type username & password
again for three times.

My question is:
How can I send a custom reply message to windows dial-in users?
or If I cann't do that, So how can I command to their windows OS for
indicate a windows failure message?
Should I send a message with specific format?

I'm waiting for your answer...
Thank you

Hi, everyone!

What is the meaning of __FILE__ and __LINE__ in the following code?

sprintf (s, "_Assert: %s, %d",__FILE__, __LINE__ )

Another question, where is the two variable defined?
Are they compile system variable?

Thanks in advance.
George

___FILE___ is a macro returning the current file. ___LINE____ returns the current line. These are used in debug mode to show you where assertion occur.

sprintf (s, "_Assert: %s, %d",__FILE__, __LINE__ )

will show you the message _Assert : Main.cpp, 123, meaning that this sprintf command was executed in the Main.cpp file at line 123.

However, you can change the meaning of __LINE___ with the #line precompiler directive, but defaut value is current line.

And why you would want to #line something STILL has me beat. Unless you're doing some serious code obfuscation. Confused | :confused:

Hey ! I know ! Do not blame _me_ for it, since I've only picked up his sample code, and he probably just asked about a piece of code which he had also not written, so we are not the dumb people in the story. Poke tongue | ;-P
