thanks first,
DirectShow and DirectDraw, which one will be better
for rendering video?
DirectDraw's direct Video Memory access (only memcpy(..) )
vs.
DirectShow's Interface ( a few api call)
which one win?
By the way, i found that when i use DirectDraw to draw some video frames, existance of Windows MediaPlayer(it may be a instance of DirectShow i think  ) is taking affect on my program's performance..which was better.
i guess DirectDraw has some connection with DirectShow,,,
what would you like to think about?
thanks again for your time

Hi~
Is there any function which is used for searching a substring?
for example:
LPWSTR a_string = _T("abcdef");
I would like to cut "cde" out and make a new LPWSTR point to it.
How?
Thanks

If you absolutely positively must use a C-style string, then _tcsstr() is the way to go. Returns a LPTSTR to the position of the first found substring in the original string or NULL if not found.
If you don't really need to use C-style strings, get on the train and use a std::string or std::wstring and its substr() function.
Note! If you explicitly use LPWSTR (as in your question) instead of LPTSTR, then you shouldn't use _T(), but rather L. Otherwise you'll confuse yourself and others by being inconsistent. In other words:
LPWSTR strForcedUnicode = L"abcdef";
LPTSTR strMultibyteOrUnicode = _T("abcdef");

here some functions i wrote recently
i have been planning to rewrite them (wrote them in a hurry)
if you want to replace "cde" then just just do
StrReplace( a_string, "cde", "What to replace it with" );
char * SubStr( char * String, long Start = 0, long Length = 0 )
{
if( Length < 1 || Length > (signed) strlen( String ) )
{
Length = strlen( String );
}
char * Result = new char[Length+1];
long lPos = 0;
for( long i = Start; i < Start+Length; i++ )
{
Result[lPos++] = String[i];
}
Result[lPos] = '\0';
return Result;
}
long StrFindFirst( char * String, char * StringFind )
{
for( long i = 0; i < (signed) strlen( String ); i++ )
{
if( !strcmp( SubStr( String, i, strlen( StringFind ) ), SubStr( StringFind, 0, strlen( StringFind ) ) ) )
{
return i;
}
}
return -1;
}
void StrFindAll( long * Array, char * String, char * StringFind )
{
long count = 0;
for( long i = 0; i < (signed) strlen( String ); i++ )
{
if( !strcmp( SubStr( String, i, strlen( StringFind ) ), SubStr( StringFind, 0, strlen( StringFind ) ) ) )
{
Array[count++] = i;
}
}
Array[count] = '\0';
}
long StrFindCount( char * String, char * StringFind )
{
long count = 0;
for( long i = 0; i < (signed) strlen( String ); i++ )
{
if( !strcmp( SubStr( String, i, strlen( StringFind ) ), SubStr( StringFind, 0, strlen( StringFind ) ) ) )
{
count++;
}
}
return count;
}
char * StrReplace( char * String, char * Find, char * Replace )
{
char * NewString = new char[];
long fCount = StrFindCount( String, Find );
long Found[sizeof(String)];
long fPos = 0;
long nPos = 0;
long oPos = 0;
if( fCount > 1024 || fCount < 1 ) return NULL;
StrFindAll( Found, String, Find );
while( oPos < (signed) strlen( String ) )
{
if( oPos == Found[fPos] )
{
fPos++;
for( long x = 0; x < (signed) strlen( Replace ); x++ )
{

}
oPos += strlen( Find );
}
else
{
NewString[nPos++] = String[oPos++];

Hello,
I dont normally ask stuff like this, but I haven't been able to find an answer anywhere
I'm writing an app in windows(MFC) (I have what I think is at _least_ a basic understanding of writing these things, but windows programming is not my forte)
I'm looking to find mouse coordinates in the client area, an easy task you might think...
But alas, no.
The app has 5 ctrl bars dotted about, 2 of which start docked to the sides, and 1 toolbar/ctrlbar, which starts docked to the top. I can access the ctrl bars and do stuff when buttons are clicked and sliders are slid.
hmmm. lets say its a paint app (NDA's etc :/)
what i want to do is pick a tool from the ctrl bar, which i can do, and draw onto the main white bit of the window(the client area, if im correct).
But, because I've got docked things, ScreentoClient doesnt work the way I'd like it to:
GetCursorPos(&c);
ScreenToClient(AfxGetMainWnd()->m_hWnd, &c);
This doesn't return the cursor relative to the TopLeft of the white bit, but to the point below the menubar, where I assume the windows actual client area starts.
So I supose what I'm asking is how do I get the TL corner of the white area? or even if it has different name, what is it called, so I can at least look for the right thing, clientArea isnt tuning up much for me.
I hope that all made sense to someone at least.
Thanks in advance to anyone who takes the time to look at this.

Sorted it now, turns out that the white bit was a seperate child window or similar, not too sure. I:m building off of some other code.
But it works now, and thats what matters
|
|
|
|
|
Does anyone know where i could get a copy of it?
my copy of VS doesnt seem to come with it.

|

tried google?

That question is getting kinda annoying,
if i hadnt tried google first then why i post here first?
http://www.google.com/search?q=windowsx.txt&sourceid=mozilla-search&start=0&start=0&ie=utf-8&oe=utf-8
do you see anything helpful ?
i see a microsoft artical( doesnt provde much info ), and some non-relative links

Maybe it's this?
I'm sorry if you're getting annoyed,but I'm only trying to help!
I usually find files by searching google on filename + download
Hope this link is what you're looking for.

no, thats a prog someone wrote for TI-83 Graphing Calc's
although it does have a document name windowsx.txt it was written by the person who wrote the prog and is not the document im looking for
the windowsx.txt file im looking for is a microsoft sdk document with details about Message Crackers
ie. HANDLE_MSG()

If you want to zoom a bitmap, that is the same as stretching it. So use the StretchBlt() function. By specifying the destination coordinates to be larger than the source coordinates you will get the effect of zooming in. By making the destination coordinates smaller than the source coordinates you get the effect of zooming out.
Look up StretchBlt() (or CDC::StretchBlt()) in MSDN for more information.

hi all!!
i have a small problem. i have designed an application which uses MS-ACCESS to log data. now, my application can be started only by administrator. when i log in as any other user other than the administrator my application will not start. but if i had started it as administrator and then logged in as any other user, it should run. The application no doubtedly runs but the the logging does not happen. i think this happens because, the databse gets closed when i log off as administrator. is there any way that i log off but the database does not close. or any other solution that u ppl can suggest me.

are you sure, your app is running after logout??
is it a normal windows app? I'm sure, all user-apps are killed on logof.

my application is interfaced to a driver that i have written. the application is destroyed no doubt. but the driver is not until shut down. so when i log in i re-create the user-land windows application. will event log work in my case instead of database?

I wrote a service, and this service has some connections to a access-databse and a ms-sql server database... and it works quite well.
so... theoreticly.. your approach should work

ADO. Better yet, use raw OLEDB.
