I'm about to pull my hair out on dealing with Regex groups and captures.

From what I can tell groups are simply sub-matches - the ability to search within a match for something. I still can't figure out what captures withing groups are for.

However, here's the main problem for right now:

Assuming the following source string: A1 B2 CD D8 EF GH

If I use the pattern: ([A-Z])\\d
I get the A1 A B2 B D8 D

If I use an unnamed group: (?:[A-Z])\\d
I get the desired A1 B2 D8 results

Help!

If those are Perl regexes (and they look like it) then the () in the regex work for both grouping and saving of matched text. The (?:) syntax is for grouping only. In your simple pattern, it won't (shouldn't) have any effect on what's matched. IOW, /[A-Z]\d/ matches exactly the same as /([A-Z])\d/

Thanks Michael, but I finally figured it out. It's C++ using the .NET regexp classes. I'd post the resolution, but all my typing needs to be on the book. Right now I'm looking at trying to get to bed by 5 so I can get up at 10 and get two more chapter's edited by Monday morning.

Thanks again!

Hello, I'm new to Windows Application programming and I have a couple of questions. First, I'm wondering how do I check the value of a CHECKBOX? I setup the resource and I used an AUTOCHECKBOX for it, but I need to know if the value is checked or not. How do I go about that?

Also, I am trying to create a COMBOBOX that will display a list of directories that the user can select. What are the basic things I'll need to get that done?

Thanks.

IsDlgButtonChecked() reads the state of a checkbox.
CB_ADDSTRING adds a string to the end of a combo. CB_INSERTSTRING adds a string at any index. CB_GETCURSEL gets the index of the selected item.

using tom in Richedit

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.

If add #include "initguid.h" in MyEditview.cpp i got these 5 errors.

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.

Thanks once again to reply soon. Now please if you have a sample project that uses "tom" with rich edit 2.0 or 3.0 please send me or you have a link which i can found some more useful things about it. please tell. Thanks a lot.

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.

Ryan Binns24-Jun-03 14:59

24-Jun-03 14:59

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.
