If you want to calculate time elapsed between two events

then u can calculate it by getting system time when event get

and on another event again get another snap of the time and simply calculate the diference

hope this will help u

I need to pass the macro __FUNCTION__ to a constructor (it's for error handling) but that macro will not work on any compiler.

What I want to know is if there is a way of knowing if the macro is avaiable with pre-processor directives. Something like:

#ifdef SOMETHING
  MyConstructor( int );
#else
  MyConstructor( void );
#endif

Where SOMETHING is only defined if __FUNCTION__ is avaiable. Is this possible? If not, is there any other way?

Thanks in advance

Can't you just use:

#ifdef __FUNCTION__
...
#endif

I dont know. I dont have the means to test it. My compiler (VS6) does not support the __FUNCTION__ macro. You think it will work?

__FUNCTION__ was added in VC7, so you can test for the existence of __FUNCTION__ by checking the value of _MSC_VER (the compiler version).

Hi,

i might misread you but if i'am right you would like to write some kind of lexical analysis in mfc, don't you?

Well i can't serve with an mfc lexical analysis but during my studies i had to program a compiler for a so called language pl/0, which is kind of a pascal dialect. My solution does a lexical & syntax analysis and even produces code for a small virtual machine. It is all written in C, but really straight forward and perhaps useful for you.

If this isn't exactly what you have been looking for, then just ignore my reply.

You may search in google for flex. flex is an open source generator for lexical analysis. It is written in C but als has a C++ version. Lats time I used it I had quite some trouble to get it compiled using VC++, but maybe its improved. It saves you al lot of work and you can easily integrate it in your code

Hi all

Working on converting a 32-bit server application to a x64 executable for performance comparision, but there is something wrong with the application or it's settings and I'm beginning to run out of ideas.

The project runs great in 32-bit.
It's a C++ application that has dll-files which I personally compile in 64-bit, shouldn't be any other except systme files.
Checking dependencies and they should all be 64-bit according to Dependency Walker.
It compiles without problems, gives a few warnings but that's no big deal since they are all related to 32-64 bit conversion and none should be of any relevance to this problem.
But, when I try to run or debug the 64-bit version I immediately get an error, Unable to start application. "This application has failed because the application configuration is incorrect. Review the manifest file for possible
errors. Reinstalling the application may fix this problem." No matter how early in the app I set any breakpoint I can't reach it... yet it doesn't seem to be any regular link error. The application config is the same as for the 32-bit version except that necessary x64-settings are changed is VS2005 project settings.
I'm currently running out of ideas, trying to find any tips out on the net and if I don't find anything I'll probably have to start up the whole project from scratch again... although the code would still be written it's a small mess since I didn't create the project earlier and I'm not 100% sure of all the project settings.
If anyone can confirm that these things shouldn't have anything to do with the problem I would be happy, or even better if you have any great tip for me:

The project was previously setup in VS2003 and VS2005_BETA, now I'm running VS2005 Pro
I'm currently running it through Terminal Server on a x64 Server 2003, using a regular WinXP as workstation to connect with.

As I said, I really do appreciate any tips.

TIA

Hi there,

I'm using some CDialogBars in my Application. If they are floating and I click the close-button the controls on the bar disappear. But the window containing the bar remains on screen.
It disappears only when dragging the empty window on a position where it could dock.

Using exactly the same dialogbar in an example application worked fine.

Does anyone have an idea why it behaves like this?

How do I keep menu attributes that exist when the menu refreshes?

I am trying to disable some menu items in a menu. I am successful in getting the menu items disabled using the function SetMenuItemInfo; but when the menu refreshes the items are re-enabled and I don't want that. Is there anything that I can do to disable menu items from refresh or recreate of the menu?

thanks,
