Um strange. If pBuf doesn't become corrupted then you should not have an ASSERT.

I would tend to alter the code back to how you had it and step through with the debugger watching the value of pBuf.

I guess you are masking a bigger problem here!

Okay I put the code back how it was (good thing I'm using SourceSafe). When stepping through the code, this is what happened. After stepping through the line where the pointer is allocated (see line 1) the value in the watch window is
0x01970190 "ÍÍÍÍÍÍÍÍÍÍÍ" unsigned char *
after stepping through line 2 the value is:
0x0018f760 "ÐÏà¡±á" unsigned char *

here are the lines:

Line 1: pBuf = new BYTE[nLength];
Line 2: SafeArrayAccessData(varBLOB.parray,(void **)&pBuf);

Also, I see the type is listed as 'unsigned char*' in both, and pBuf is declared like this:

BYTE* pBuf;

When using SafeArrayAccessData(), there is no need to allocate memory for the second parameter.

As always you're exactly right. I removed the 'new' allocation from my code and it works just fine, and no memory leaks!! Thanks for the millionth time.

when i tried to 'delete pBuf' it asserted in "dbgheap.c" in the above-mentioned function. Now when I trie to recreate it using 'delete [] pBuf', it crashes in "compip.h" on line 303 in this code:

~_com_ptr_t() throw()
{ 
    _Release();

I want to merge cell of the word by VC and my codes as follow:
for(int i=3,j=0;j{
c1.ReleaseDispatch();
c2.ReleaseDispatch();
c1=pTable->Cell(i,1);
c2=pTable->Cell(i+DayCount,1);
c1.Merge(c2);
}
the first time this section codes work well, but the second time bug happened.
and if I merge the first row in the seconde time and don't merge the first column it works well too.and continuiously merge the first column buf happned too,why?

Detect default language 'en' or 'de'

Hi,

how do I detect users's default language in something like 'en' or 'de' or 'en-us'? There is GetUserDefaultUILanguage() but i don't know how to convert into a RFC3066 style text representation. Also I am having difficulties to detect if user has per default 12 or 24 hours format selected.

Thanks for help.

Have you tried GetLocaleInfo().

Call the function with LCTYPE set to:

LOCALE_ILANGUAGE - IIRC gets the language identifier.
LOCALE_ITIME - Will get 12 / 24 hr format

to get the appropriate information.

Get / Set Windows Title Bar Font, Text Colour and Size

I'm really struggling to find anything that would enable me to do this. It's driving me crazy, as i know everything about the title bar now, except this.

I'm looking for the kind of options got in NT Display>Appearance tab where the title bar Item has the option to set a variety of properties, including font, colour, etc.

I get the size of it, and the size of the icon, but the one thing I can't do is the size / font / color of the text.

Anyone got any ideas?

Cheers

Interesting. This method is completely undocumented in MSDN.

Can you tell me which DLL it's in? And where I can find a list of related Enums + structs?

I have a ClistCtrl derived class which is ownerdrawn and virtual.
I have been using it quit some time now without any problems.
But when I tried to use this class in a application with manifest included, the darn thing doesn't work proper.
I'm having a lot of paint problems.
Every mousemove over an item causes this item to be redraw.

Does anyone have an idea what is causing these problems.

Problem using direct draw in C?

Dani10000124-Sep-04 2:13

Dani100001

24-Sep-04 2:13

I am developing a project using C instead of visual c++, and when I call for example CreateSurface I must use following syntax:

IDirectDraw_CreateSurface(pdd,&ddsd,&pdds,NULL)
or
pdd->lpVtbl->CreateSurface(&ddsd,&pdds,NULL)

Otherwise I get an error like CreateSurface missing method...

Someone told me that :

All the COM functions are in the virtual method table of the
object. c++ handles that, but in c you have to do it manually.

use the macros defined in ddraw.h.

This seems strange to me is there any simplier way to do this?

And when I use:

DirectDrawCreate(NULL, &p->lpDD, NULL )

I get a compiler error:

error LNK2001: unresolved external symbol _DirectDrawCreate

So how should I call DirectDrawCreate....

Is there any "smart" compiler settings that I can use to let the compiler to treat the Direct draw functions as they where in Visual c++ ???

I have included ddraw.h and linked to ddraw.lib if you wonder...

Please help, cheers Dani

Exeption handling

Cedric Moonen24-Sep-04 1:51

Cedric Moonen

24-Sep-04 1:51

Hello !
My program is sometimes throwing unhandled exeption. I would like to handle this exeption to take some appropriate actions (such as print debug informations in a file).

So, I would like to know first how to get this exception and call a function. And second, I need some advices to debug my program: in fact, these exceptions occurs very rarely so I need a way to know what happens exactly (so, for example at wich line of code, the state of the latest variables, ...). Any advice will be great Wink | ;-)

Thanks
