DirectShow isn't quite as bad as Mr. Simmons states (maybe he should have held out for the 7-
figure jobs  ) but its COM interfaces and semi-confusing documentation can make the learning curve
tough.
I've found it superior to its predecessor VFW, mostly because of WDM driver support. It's also
very flexible once you get the hang of it. That, unfortunately, can take some time (I mean
blood, sweat, and many tears) 
That said, h.263 is no longer supported on DirectShow. As always with DirectShow, you WILL have
a hard time if you need to use a certain codec and you don't have one. The codecs included with
Windows are extremely limited. If you have a 3rd-party codec that is wrapped in a DirectShow
filter then you're in good shape.
My advice is get the Platform SDK (where the DirectShow SDK now lives) and study the features.
Make sure it's going to do what you need before you commit the time. The samples included in
the SDK work. Use them. It's sometimes nice to have working code you can study when the
documentation is vague.
Good luck!

Nah - it really does suck as back I say it does. I remember talking to Microsoft about something and walking away from the conversation completely aghast at the response I got. I don't remember exactly what it was we were talking about (I think my subconscious is blocking it), but I think it involved identifying devices you were trying to build filters for.
It was such a big pain in the ass that I promised myself that I'd never again go through the anguish and pressure of having to deliver something written for the piece of shit that DirectShow really is.

You must use of LoadLibrary it returns a handle to file then call GetProcAddress function for gets address of function on the dll and in the end you must use of FreeLibrary function.
Does this informations helpful for you?

Hi all,
i am facing problem with AfxFormatString, as the the Parameters it will take from only "%1 to %9" as Arguments for subtitution from Resource String.
Please help me to Append beyond that, I Mean after 9 th Parameter.
code:
-----
Resource String :
String ID
---------
IDS_GTD_WIZ_SET_STANDARD_CONTROLLER
Caption
-------
"It is necessary to set one or more equipment other than %1, %2,\n%3, %4, %5, %6, %7, %8,\n%9 and %10 to Communication ettings."
Here i am trying to Subtitue this %1,%2,%3,%4,%5,%6,%7.... upto %9 but after subtituion of %10 i am not reflecting that.
CString lC_Str_DriverArray[10];
UINT lui_Index = 0;
lC_Str_DriverArray[lui_Index++].LoadString(IDS_GTD_WIZ_CONTROLLER_BARCODE);
lC_Str_DriverArray[lui_Index++].LoadString(IDS_GTD_WIZARD_REFID);
lC_Str_DriverArray[lui_Index++].LoadString(IDS_GTD_WIZ_CONTROLLER_GATEWAY);
lC_Str_DriverArray[lui_Index++].LoadString(IDS_GTD_WIZ_CONTROLLER_ETHERNETDOWNLOAD);
lC_Str_DriverArray[lui_Index++].LoadString(IDS_GTD_WIZ_CONTROLLER_PRINTER);
lC_Str_DriverArray[lui_Index++].LoadString(IDS_GTD_WIZ_CONTROLLER_VIDEORGB);
lC_Str_DriverArray[lui_Index++].LoadString(IDS_GTD_WIZ_CONTROLLER_RGBOUTPUT);
//Extended Step Addition
lC_Str_DriverArray[lui_Index++].LoadString(IDS_GTD_WIZ_EXTENDED_MEMORYCARD);
lC_Str_DriverArray[lui_Index++].LoadString(IDS_GTD_WIZ_SOUND_OP_UNIT);
lC_Str_DriverArray[lui_Index].LoadString(IDS_GTD_WIZ_EXTERNAL_IO_UNIT);
//Load error message
AfxFormatStrings(lC_Str_Msg,IDS_GTD_WIZ_SET_STANDARD_CONTROLLER,(LPCTSTR*)lC_Str_DriverArray,10);
Here after 9th String i am getting Problem. in %10 it is subtituting as %1 what to do.
please help me out.

I would advise you to use boost::format[^]
Boost is a library of very high standards. So high, parts of it will find its way into the upcoming C++ standard. It is completely free.
Another possibility is building your message in a std::ostringstream, and get it from there.
std::ostringstream stream;
CString tmp;
stream << _T("It is necessary to set one or more equipment other than ");
stream << (LPCTSTR)tmp.LoadString(IDS_GTD_WIZ_CONTROLLER_BARCODE);
...
std::string s = stream.str();
CString s1 = s.c_str();
Failure is not an option - it's built right in.

hi jhwurmbach,
I Understand your answer. But the Code T("It is necessary to set one or more equipment other than "); must not be hard coded and this is the String Table of the Resource with %1 %2 %3 .....
and Dynamically it must subtitute accordingly.
please let me know any solution for this.

OK. I see.
You got the text with the %1-replace markers inside and can not change it.
How stupid!
You could have a regex[^] exchanging all '%digit' by '%digit%' and use something like this
cout << boost::format("writing %1%, x=%2% : %3%-th try") % "toto" % 40.23 % 50;
(example from the boost-page)
Ok. This idea comes out of desperation.
Failure is not an option - it's built right in.

Check your previous question - I provided enough code to get you going down the right path.

Yes. Check out SetNamedSecurityInfo().

Someone can recommend me a free and easy setup maker for Visual C++ aplications?
-I have used InstallShield but is too complicate for me.
-I used Inno Setup but makes some strange things... After making the installer and installing the app it only shows a Messagebox that says "Welcome to my aplication" and then closes. O_o
-I used too Smart Install Maker but it is not free, and shows a window during installation of the app that says "This is made with a no paid program" or something like that. Of course, I cannot use it...
Any other idea?
Thanks

whats the difference between
char test[] = "Hello";
and
char* test = "Hello";
in both cases is "Hello" allocated on the stack?? 
|
|

Haroon Sarwar wrote: char test[] = "Hello";
This is an array of characters. This is not a pointer.
Haroon Sarwar wrote: char* test = "Hello";
This is a pointer to an array of characters. Note that test will contain the address of the given array and not the real data.
For proof enter the following in the debugger
&test
test
ptest
&ptest
You will see that the first two are same, but the last two are not.

There are notable differences between:
Haroon Sarwar wrote: char test[] = "Hello";
Here test is a character array(i.e. a const pointer to a memory area containing six characters -remember the '\0' string terminator-), initialized with the string literal "Hello" .
Haroon Sarwar wrote: char* test = "Hello";
Here test is a pointer to the string literal "Hello", that is a read-only memory area.
See the following sample code:
char test1[] = "Hello";
char * test2 = "Hello";
test1[2]='p';
test2 = test1;
test2[2]='p';
Hope that helps

If you do these within a function they will both get allocated on the Stack, one array and one pointer. The actual "Hello" text in each case will end up as static data within the executable image. char text[] = "Hello"; will give you an on stack copy of this data at runtime. const char* test = "Hello"; will give you a pointer to the string stored in the image memory. char* test = "Hello"; will almost certainly be the same.
If you do these at file scope, i.e. in a .c or .cpp file but not in a function then the "Hello" text is still stored in the image and in this case so is test[] or test. With a reasonable optimising compiler with string merging char* test; will probably end up pointing to the same memory refered to by char test[] which will be the one and only original "Hello" text in the loaded image.
Have a look in the debugger at runtime and see what the address values are in each case. You'll soon spot the pointers to stack memory as opposed to pointers into the loaded image, the ranges will be quite different.
Nothing is exactly what it seems but everything with seems can be unpicked.
