I'm kind of new to MFC. I used to using Borland.
How can I convert a CString to a char array[40].
To be used as a filename I will open using old style ansi C fopen.
Additionally I noticed that in Microsoft VC++ you can not write a int long or double using fstream or iostream. This is pretty Lame. In Borlands compiler you write a double
somefile<

Simply copy, ie assuming your CString object is cstringObject...
ASSERT(cstringObject.GetLength() < 40);
if (cstringObject.GetLength() < 40)
lstrcpy(array, cstringObject);

Hi expert,
I have a problem with the CList class. Microsoft does not provide a copy constructor for CList. Is there any way or alternatives that i can use beside than CList. I have tried to return a CList from a function but the compiler told me that there is no constructor to copy the list. I dont want to develop my own list because i dont have time for that. STL list is tedious to use and compatibility errors often pop up.
So please help.
thank you.

Create a CList in the fn that calls this fn, then
pass the CList by ref or by a pointer to the fn,
then fill the list in the fn. You can return the
number of items added to the list as a success/
failure check.

Daniel

Thank you

I was wondoring, how do i implant Music in a dialog??
I try to do it with "PlaySound"
It worked, but i could control the Dialog right, when the Wav file played,
it was like it locked up. Is the a way to avoid this??
Thank you.

Hi,
if you want to have access to the window/dialog while playing a sound you have to play the sound asynchron. That causes the function to return just after the sound has started. If you want to lock the window while playing use the synchron-playing feature.
Hope it helps - Mario

Ok, how do i implant that, i didnt find any info on MSDN.
??
Thank you.
|
|
|
|

Ok, the implementation is easy :
#include <mmsystem.h> // dont forget to link winmm.lib
// play from file synchron
sndPlaySound( "file.wav", SND_SYNCH);
// play from file asynchron
sndPlaySound( "file.wav", SND_ASYNCH);
// to play from memory or whatever use
sndPlaySound( "file", SND_MEMORY|SND_ASYNCH);
-> there are some other flags - look @ msdn

I implanted the code:
sndPlaySound( "file.wav", SND_SYNCH);
in my butten.
and #include <mmsystem.h>
and linked winmm.lib
but i get this error.
error C2065: 'SND_ASYNCH' : undeclared identifier
Thank you.

Sorry,
the right flag is called SND_ASYNC and not SND_ASYNCH.
You can read about all in MSDN.

... and the same for synchron playing:
SND_SYNC and not SND_SYNCH
---------------
P.S.: If you got problems with unknown flags take a look at the header-file. All flags are declared there.

Hello,
I'd like to write a Program that
can be executed in pure DOS.
Is there a way to write DOS-Programs with Visual C++6?
thanks in advance,
FoxHunter
|
|
|
|
|
File -> New
Projects tab
choose 'Win32 Console Application'
Regards,
Daniel
|
|
|
|
|
Yes, but this will actually create a program that requires Win32 -> You want be able to run this program only in DOS;P
|
|
|
|
|
Yes...only DOS! 
I'd like to program a little Password-protection that starts before the Desktop ist being loaded.
I'd like to start the program from the
autoexec.bat
I have written that program in quickbasic, but i'd like to program it in c++
|
|
|
|
|
Oh dear,
someone takes a simple bootdisk, removes the entry from your autoexec.bat and runs windows as usual -
and what about your password than ??? Why don`t you use the bios-password protection ??

Yes, you're right...but i want to program more dos programs than just that crappy password protection.
I could do that in qbasic, but i don't like the programming environment of qbasic.
So how can i do that now?
thanks

I dont really know if you can write real dos-code with vc. I have never tried.
Maybe use an older DOS-Compiler from Borland or something else.

You need VC 1.52 I think.
This is the last version that you can compile and make dos app.
Good luck,
Dror

Hi,
I think you could try (and I know its not VC++) downloading Turbo C++ from the Borland museum - a bit naff but it still works for DOS stuff.
cheers,
Andrew.
