You're entitled to your opinion, but I disagree. WTL is a cleaner model than MFC, and templates don't make it any more complex than MFC. It does for developers using the UI what ATL does for developers using COM.
You can use WTL without using SDK calls, or if you wish you can use SDK calls, just like in MFC. I don't understand what you mean by 'more advanced windows programming config', so I can't really address that.
However, it is not an MFC clone, it doesn't have built-in document/view, serialization or docking window support.
The best intros to WTL are those on CodeProject, (of course).
WTL should be an essential part of a C++ developer's toolkit if they are considering developing for the Windows UI.

hi, all:
I've developed a bho plugin for internet explorer. It simply receive the DISPID_BEFORENAVIGATE2 event and change the address in the address bar. It's event-driven and I think it will not cost too much cpu. But to my surprise when it's loaded into IE, the cpu usage turns to be 100% and I can do nothing else.
Why it costs so much cpu and how to resolve this problem?
Thank you very much!

Hi, guys,
do you know of any WTL code wrappers for Scintilla?
Thanks a lot,
Igor.

i create a com dll using an ATL and attribute and i try to register this file when i call LoadLibrary( DllPath ) i got a null pointer and i don't know why.
some computer print this message box "the application failed to start because MSVCR70D.dll component not found"
can i make a attributed ATL7 com dll independant on any other components

When you compile in debug configuration, it links with MSVCR70D.dll instead of MSVCR70.dll
MSVCR70D.dll is the debug configuration dll of vc runtime.
To solve this problem, all you need is the MSVCR70D.dll on the box where you are trying to register your Atl7 COM server.

You can remove that dependency but going to Ptoject/Properties, go to Code generation and selecte "Mulithreaded Debug" instead of "Multithareded Debug DLL"

I need to learn fast about the creation of ATL Composite Control Projects.
Where could I find abundant information about this??.
Maybe a tutorial in the WEB.
Maybe a book.
I have read a lot about ATL projects but I need something specific about Composite Controls. Something that teach me how should I move inside this kind of projects.
I have some good skills with MFC and I'm learning general ATL stuff.
Thank you very much.

Just use the composite control wizard. The composite control is basically a non-modal dialog. I suggest you use WTL for the GUI-stuff, as it makes your life a whole lot easier.

Hi.
I have a WTL 7.5 app created in VS2005 on XP.
In the app I was intending to make use of various STL containers. I began by entering:
using namespace std;
just under my header declarations, BOOM!
I instantly got 11 errors, 5 pairs of:
error C2006: '#using' : expected a filename, found 'namespace'
fatal error C1190: managed targeted code requires a '/clr' option 
and 1:
BSCMAKE: error BK1506 : cannot open file '.\Debug\DispInterface.sbr': No such file or directory.
I've rummaged around my settings and could see nothing that cause this (though obviously, I expect I'm missing something). Anyway, I continued with the app as I could use std:: to use the containers I wanted, only to find when I called push_back on a vector I got a heap corruption (C0000005).
I can only presume these are connected as I understand neither.
Any insights would be greatly appreciated
Thanks
Tom

Weird - it seems to be parsing using as #using!
How about using the std namespace qualifier directly, e.g.:
std::string str = "Test";
Does this work OK?
FWIW I use the STL with all my WTL/ATL apps with no issues, however, I avoid using namespace .... I prefer to specify the namespace directly.
Should I use using namespace std in my code?[^]

And me - the only namespace I use is boost::lambda, and then only in the smallest scope I can find.

'#using' - sure there's not a rogue '#' in there?
Also - I've used STL and WTL together with *no* problems, so I'd suggest it isn't going to be that...

Firstly, thanks for the speedy responses 
there's certainly no rogue '#' in there, the file begins as follows:
<br />
<br />
#pragma once<br />
#include "idlobject.h"<br />
#include "IDLMethod.h"<br />
#include "IDLProperty.h"<br />
<br />
#using namespace std;<br />
<br />
class CDispInterface :<br />
public CIDLObject<br />
{<br />
<br />
std::string test = "Test";
Worked fine, but:
std::vector< CIdlMethod* > m_vMethods;<br />
CIdlMethod* pMethod = new CIdlMethod(); <br />
m_vMethods.push_back( pMethod );
fails with a heap corruption 
PS. thanks for the link to that FAQ page.

Ummmm - it should be using namespace std;, not #using namespace std; - that's what I meant by a rogue #. C++ namespaces are used with a plain using. #using pulls in a .NET assembly[^].

Ah Ha!
Goodness knows where I got that from 
Thanks Stuart

This requires setting property "common language runtime support".
You can do it by setting project properties-->Genearal-->Project Defaults--> common language runtime support-->common language runtime support

Not sure about this one, but may be this[^] helps you.

It's bizare that the comiler is looking for CLR support when I'm not using anything I'm aware has even a whiff of a connection to it.
When I set the /clr property It just ran into the '/MTd' property and compiling ceased. Since I rely heavily on threads in this app that's kind checkmate as far as 'using namespace std;' is concerned.  
thanks to an article I got pointed to by an earlier comment I'm now resolved to using std:: anyway. Now I just have to figure out what's going on with my std::vector
Thanks

Let us take a simple function
::MessageBox(0,data.c_str(),"log",0);
where data is a std::sting type.
When i change the build type to unicode ,this will spit out error
error C2664: 'MessageBoxW' : cannot convert parameter 2 from 'const char *' to 'LPCWSTR'
How can i feed in the underlying data of a std::string type(const char *),so that it builds smoothly in both MBCS and UNICODe builds.
|
|
|
|

typedef std::basic_string<TCHAR> tstring;
...
tstring str = _T("Hello, World!");
::MessageBox(NULL, str.c_str(), _T("Test"), 0);
The above will work in both MBCS and Unicode builds.
Or see here[^].
FWIW I always use std::wstring and build for Unicode and for Win9x support I link with the MS unicows library.

Smart choice, as going from ANSI -> UNICODE is a pain in the ass. I just wish all platforms and libraries used the same Unicode encoding scheme. I recently tried to do Unicode for different platforms. P.I.T.A! Windows uses UCS2/UTF-16 internally, while on Unix you use either UTF-8 (char) or UTF-32 (wchar_t). Dear god in heaven, that amounts to a huge frickin layer of string crap.

You are mixing two types and the literal string is the problem:
data.c_str() is UNICODE, and "log" is not under a UNICODE build. Change "log" to L"log".
::MessageBox(0, data.c_str(), L"log", 0);
