I tried it as following:

=============================================
HINSTANCE hInstance;
VERIFY (hInstance = ::LoadLibrary("c:\\windows\\system\\OuterDLL.dll"));

typedef DWORD WINAPI (SQRTPROC) (DWORD,char*); //Line 86
SQRTPROC* pFunc;
VERIFY (pFunc = (SQRTPROC*) ::GetProcAddress(hInstance, "MyFunc"));
==============================================
And I got in compilation the following errors :

MyDLL.cpp(86) : error C2059: syntax error : '('
(87) : error C2065: 'SQRTPROC' : undeclared identifier
(87) : error C2065: 'pFunc' : undeclared identifier
etc...

LPSQRTPROC pFunc;
VERIFY (pFunc = (LPSQRTPROC) ::GetProcAddress(hInstance, "MyFunc"));

left over IDC_ values in resource.h

I have a dialog that's undergone heavy modifications, and I'm left with a ton of extra IDC_ values for controls that no longer exist.

Is there any utility or way to have it remove the unused control values?

I've also been expericing "duplicate control IDs" when renaming some. The bugger is that there are no duplicates. There were, but those were renamed or deleted, but it thinks they are stil there.

Thanks in advance

Go to View->Resource symbols. The ones in use will have a check mark, so you can delete the ones w/o checks.

Anti-alias font in WebBrowser control

26-Nov-01 7:39

Hi All,

I've got a big problem and could somebody kindly give me a hand?

The requirement is to use WebBrowser control and display content in Anti-alias font. Assume 'smooth edges of screen fonts' display property is not checked. (we can't assume it is checked) How I can make the content of WebBrowser control render in Anti-alias font?

I've got some ideas but most of them are proven to be not working. Now, I'm thinking of solutions like creating a 'HFont' with 'CreateFont' that takes a 'ANTIALIASED_QUALITY' 'fdwQuality' parameter. And put the HFont to system by 'AddFontMemResourceEx' function. And let the HTML to specify using the new font. Do you think this method can work? any other good suggestions?

Thx and regards,

AddFontMemResourceEx: adds the font resource from a memory image to the system.

Put this in your .h:

#ifdef __cplusplus
extern "C" {
#endif
extern int x;
#ifdef __cplusplus
}
#endif

and this in your .cpp:

#include <···.h>
int x;

Radio Box

If I have 2 radio boxes and I want to make sure the user can check only one of them at a time (ie if the user checks one, the other gets automatically unchecked).....then how do I do this?

Thanks.

Re: Radio Box

lets say you have two pairs of 3 radio buttons [thus 6 total].
use the WS_GROUP style for the 1st and 4th.
Now you have two sets of 3-mutually exclusive radio buttons

Re: Radio Box

If you mean radio buttons, then have them on a group box.

Re: Radio Box

26-Nov-01 7:32

It seems if you place your group boxes with radio buttons in another group box, you can check only one button at a time effectively checking one group at a time. It needs a SetCheck() on the first button you want to start with.

Re: Radio Box

Michael Dunn26-Nov-01 9:40

Michael Dunn

The "group" attribute controls which radio buttons are linked up. It has nothing to do with being in a group box like the previous posts have said. The first radio button must have the group attribute set, the others must not have it set, then the control right after the last radio button in the tab order should have it set to mark the end of the group.

MSXML & VC++ Book

Derek Price26-Nov-01 4:40

Derek Price

26-Nov-01 4:40

Hello,

I am interested in using the MSXML parser using VC++. It seems there are endless books on the subject for VB and every other language, but I haven't been able to find one for VC++ specifically. I know many code sites (MSDN, CodeProject, etc.) have articles, but I would prefer a book. Can anyone suggest a book that focuses on the MSXML parser and VC++ (not .NET)?

Thanks!
Derek

Hi Derek

You are correct there. Nearly all the documentation on MSXML is about VB. I had this same problem an year ago.

I finally ended up using Expat - an XML parser library in C

I believe that since then there is Expat++ which is a C++ class library

I'd recommend Expat unless you very specifically want to use MSXML

I would be suprised to find one. Using it in VC++ is just like using it in VB. Import it, create an instance and call its member functions (just like all other COM objects).

Hope this helps,
Bill

I use ShellExecute to execute IE opens some CGI script like:

HINSTANCE result = ShellExecute(NULL, _T("open"), mUrl, NULL,NULL, cmdshow );

Is it true?
And when I created, the handle is result?
And how to close this dialog by coding in my program?

Please help me! thank you very much!

Re: How to handle program that I create by ShellExecute

The HINSTANCE returned is dummy. Ignore it.
I'd advise you to use ShellExecuteEx
