You may also try the easy solution :
Add your button in the ressource editor.
Doubleclick on it to open properties.
Give it a name (for instance ID_OPENFILE).
Close the window, go open the class wizard.
Select your button name in the list on the right and handle the corresponding message. All the stuff given by Himanshu will be added automatically.
Oh, BTW, Himanshu, feel free to put your code into a <pre> environment, it is far more readable.

Hi, everyone!
Please look at the following code,
--------
#if ASSERT
sprintf (s, "_Assert: %s, %d",__FILE__, __LINE__ );
#else
//...
#endif
--------
I want to know where is the precompiled directive ASSERT defined?
Is it compiler system defined variable? What is the meaning and
function of it?
Thanks in advance,
George

 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.  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.

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)

I am from Mars. My uncle is Martin. 
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,
George

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

#ifdef _DEBUG
Then ASSERT is defined
#endif

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
#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 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

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.

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.

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. 
And they still ran faster and faster and faster, till they all just melted away, and there was nothing left but a great big pool of melted butter

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.

Im using PreTranslateMessage to fetch all keystrokes that are made in a
dialog.
And I return TRUE, just as I should, for each message that I handle.
Everything works, except for F1, F12 and the windowskeys. I recieve the F1 and F12 keystrokes and return TRUE, but they seem to get handled by the application anyway.
F1 launches help, F12 closes the dialog.
How do I resolve this issue?
|
|
|
|
|
I've had the same problem recently. Seems like the MFC framework insists on handling F1 even if the PreTranslateMessage tells otherwise. The solution is to override OnHelpInfo and do nothing there. As for F12, my app activates the debugger as though a user breakpoint had been called, but this does not happen when executing the app in non-debug mode (CTRL+F5), so basically I did not investigate the issue further.
