Hello,

How can we add tom interfaces in our project and use it with Rich edit. the msdn sample code was not working for me.
Here is the code:

HWND hwnd;
ITextDocument *pDoc;
ITextRange *pRange;
POINT pt;
IUnknown *pUnk = NULL;

GetCursorPos(&pt);
hwnd = WindowFromPoint(pt);
SendMessage(hwnd, EM_GETOLEINTERFACE, 0, (LPARAM)&pUnk);
if(pUnk &&
pUnk->QueryInterface(IID_ITextDocument,(void**) &pDoc) == NOERROR)
{
pDoc->RangeFromPoint(pt.x, pt.y, &pRange);
// ... continue with rest of program
}

but this produces errors regarding "IID_ITextDocument" as i add tom.h in my program.

please give me any code sample of Text object model.

thanks in advance.

#include "initguid.h" before including "tom.h" in one of your files. If you include "initguid.h" in more than one file that uses "tom.h" you'll come up with other errors, so only put it in one file.

It seems like you're including "initguid.h" more than once. Are you including it before "tom.h"? If so, then try replacing #include "initguid.h" with #define INITGUID and see if that works.

OK. Instead of including "initguid.h", try putting this at the top of your source file:

#define DEFINE_GUIDXXX(name, l, w1, w2, b1, b2, b3, b4, b5, b6, b7, b8) \
        EXTERN_C const GUID CDECL name = { l, w1, w2, { b1, b2,  b3,  b4,  b5,  b6,  b7,  b8 } }

DEFINE_GUIDXXX(IID_ITextDocument,   0x8CC497C0,0xA1DF,0x11CE,0x80,0x98,0x00,0xAA,0x00,0x47,0xBE,0x5D);
DEFINE_GUIDXXX(IID_ITextSelection,  0x8CC497C1,0xA1DF,0x11CE,0x80,0x98,0x00,0xAA,0x00,0x47,0xBE,0x5D);
DEFINE_GUIDXXX(IID_ITextRange,      0x8CC497C2,0xA1DF,0x11CE,0x80,0x98,0x00,0xAA,0x00,0x47,0xBE,0x5D);
DEFINE_GUIDXXX(IID_ITextFont,       0x8CC497C3,0xA1DF,0x11CE,0x80,0x98,0x00,0xAA,0x00,0x47,0xBE,0x5D);
DEFINE_GUIDXXX(IID_ITextPara,       0x8CC497C4,0xA1DF,0x11CE,0x80,0x98,0x00,0xAA,0x00,0x47,0xBE,0x5D);
DEFINE_GUIDXXX(IID_ITextStoryRanges,0x8CC497C5,0xA1DF,0x11CE,0x80,0x98,0x00,0xAA,0x00,0x47,0xBE,0x5D);
DEFINE_GUIDXXX(IID_ITextDocument2,  0x01c25500,0x4268,0x11d1,0x88,0x3a,0x3c,0x8b,0x00,0xc1,0x00,0x00);
DEFINE_GUIDXXX(IID_ITextMsgFilter,  0xa3787420,0x4267,0x11d1,0x88,0x3a,0x3c,0x8b,0x00,0xc1,0x00,0x00);

This is what I had to do in a project I was just looking at. I can't remember where I got it from, but it prevented compile errors.

Hello,

I tried this one But still no luck. Is there any setting for compiler i am using windows 2000 server, and VC++ 6.0 with sp5 install and feb 2003 SDK. may be there is some compiler setting. i have no idea what's wrong here. please give me some more tips.

Thanks once again for replying soon. I am greatly Thankful.

Sorry, I can't give you any more tips. The code that I gave you compiles perfectly with VC++/sp5 because that's what I'm using. I didn't change any compiler settings from the default.

I have no idea what you're doing wrong.

How do I receive data after an completed AcceptEx operation?

bond00621-Jun-03 4:51

21-Jun-03 4:51

Hello,
I want to receive data after an AcceptEx() call. A brief overview:

1. I listen on a port and receive data with the buffer I've passed to AcceptEx().

2. When there is incoming data I process the data and send a return packet.

3. Now I wan't to receive data from the same connection again. I tried to use WSARecv() on the socket, but everytime I use WSARecv() I get an error with the error code 10014 (The system detected an invalid pointer address in attempting to use a pointer argument in a call). When I create a new socket with the socket(), bind(), listen() accept() procedure and pass it to the WSARecv() function I have no problem in calling WSARecv(), but I wan't to receive data from the socket on which I sent data. Can I use AcceptEx(), send() and then WSARecv() in this order??? How would you do this?

-----------------

Thank you for your attention,

I'm able to send the return packet and I'm able to call WSARecv() on the socket, but I always receive the data, I sent. Wink | ;)

friends
hi
this is my first mail in this forum
i am using sdk for making a dll
now the problem is when i do not use any function of the given sdk and make a dll and then when i call a dll through my client vb application
the vb do the thing which i intend to do...
now when i use any function in the same dll(i have included the lib correctly) and compile and after compiling and when i try to run my client vb application,it throws an error saying run time error 53
file not found......
so my question is some special code is to be written when i use a dll inside my dll
i have to use the dll provided with the sdk for firing important function to use the card for which the sdk is present...
thanks

As an experiment, instead of loading the inner DLL and using inside the outer DLL, load it from the executable. Does it load okay?

Try checking the dependencies of your dll (try Depends.exe). You may have included the lib and compiled it, but the compiled dll might not be able to find the win dll containing the sdk functions which you used.

CStatusBarCtrl::SetIcon() problem with icon size

Baris Kurtlutepe21-Jun-03 0:07

21-Jun-03 0:07

Hi everybody,

I'm trying to show an icon in one of the status bar's panes. The status bar is the CStatusBarCtrl and the problem is that I can only show 32x32 icons in the pane. When I load a 16x16 icon and call SetIcon() the icon on the statusbar becomes stretched to 32x32 in size, thus loses visibility of the most parts because the statusbar itself is about 18 or 19 pixels high. The workaround I've found is to create a 32x32 icon and place my 16x16 icon in the middle of that space and everything's fine. What am I doing wrong? Or is it that the 32x32 icons are the only ones one can display in a status bar pane? Any help would be greatly appreciated...

P.S: The icons that I'm using are for the WindowsXP platform and thus 32bit icons, 24 bit colour and 8 bit transparency, maybe that's a problem?

Michael Dunn21-Jun-03 5:10

When a 16x16 gets stretched to 32x32 it's usually caused by calling LoadIcon() instead of LoadImage(), or using incorrect size parameters in LoadImage().

LoadImage() worked, thank you very much. I thought I tried LoadImage() without success before, but then I must have given incorrect parameters to it. And I didn't know that LoadIcon() stretches the bitmap to system metrics, thanks again.

MFC CBitmap LoadBitmap()

20-Jun-03 23:49

Hi all,
Bit of a problem with CBitmap's LoadBitmap() function. If I make a bitmap a resource and do

BitmapObj.LoadBitmap(IDB_MYBITMAP);

The image is loaded fine, but if I do

BitmapObj.LoadBitmap("MyBitmap.bmp");

it returns 0 (failed). I've tried moving the location of the file around the local directory (debug, res, etc.) but no luck.

What do I need to do?

Obseve everything, remember more...

Re: MFC CBitmap LoadBitmap()

Ryan Binns21-Jun-03 0:53

You can't load a bitmap file like that. To load a bitmap image from a file, use LoadImage():

HBITMAP hbm = (HBITMAP)LoadImage(NULL, "MyBitmap.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);

Hope this helps,

Ryan
