Hi,
I've been trying to get my app these big sized 32 bit toolbars like in winrar. I've checked the Alpa example that comes with WTL but this just works for windows XP as Winrar's toolbar seems to work for older versions of commonctr32 aswel...
Does anybody know of a WTL app that has such toolbars? Or else, how are they created?
Thanks..

I have used WTL, how to controls are bind with variables. In MFC we used to classWizare -> Add variable, WTL does not support class Wizard.
 Write your valueble suggestions.........

The not so easy way: use the DDX/DDV support, documented here[^]

i'm using VS.Net 2003, compiling a DLL with /MDd (it links to external libs
compiled with the same flags)
the following is in the main header
#if _MSC_VER < 1300
#include <iostream.h>
#else
#include <iostream>
using namespace std;
#endif
the project compiles without error or warning, but while linking i get ...
C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\ostream(955):
error C2491: 'std::flush' : definition of dllimport function not allowed
C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\ostream(947):
error C2491: 'std::ends' : definition of dllimport function not allowed
C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\ostream(930):
error C2491: 'std::endl' : definition of dllimport function not allowed
these are repeated once per include of the header...
these methods are prefixed with the _CRTIMP2 macro, which with /MDd set, is
expanded to __declspec(import).
This in turn which chokes the linker..
note that i'm not even (explicitly) using any STL classes/templates/operators, etc
any clues on how to solve this ?

The handle to your dialog ... more than likely it would be
this->m_hWnd
Might I suggest spending some time reading about ATL and COM development, including the ATL Framework before you just dive head first into COM ...
Also refer to Michael Dunn's WTL articles, they explain some of the basics of ATL/WTL.

how can we retrieve window xp's current user's name in mfc/atl?
because i writing some program which need to read file from internet cache, which is stored under user's folder...
thx in advance...
|
|
|
|

Don't go by the user's name for that, since you can move the IE cache directory. The right way to get the dir is SHGetFolderPath() with the CSIDL_INTERNET_CACHE parameter.

can u pls gv more details on how to implement this ? from msdn and some sample in codeproject, i found we hv to include either "Shfolder.h" or "ShellFileOp.h", which is not found in my vc include folder? izzit i missed something during the installation?
beside that, i try in manual way to set the path, but i then found one problem, which this folder is protected, and using some different file system than normal file system. e.g. if we browse a file named "index.jpg", same file name is saved under the folder but we cant open the file by path <internet_cache>\index.jpg, instead it is represented by <internet_cache>\Content.IE5\EVIV8DSF\index.jpg, or may be <internet_cache>\index%5B1%5D.jpg....anyone hv any idea/experience in overcome this situation?
sorry for asking so many question...i'm new in c++ programming, and hv to finish this system in short time duration as my final year project...
thx in advance for any help...

hi, was trying to add a function [view image in new window], right above the line of save image of IE's right click context menu.
with referencing to msdn article titled "Adding Entries to the Standard Context Menu(Internet Explorer - Browser Extensions )" , i start to edit my windows registry. After adding a key named "view image in new window", and change it's value to the processing page, i later on try to add a binary value under it, with value 0x2 which only display this options when users click on an image only, but when i try to modify this binary value's value, it pop up a windows which show 4 0's as 0000, once i typed 0, it display another 2 0's, anyone hv any ideas on how this can be??
beside that, i also cant find more details on how the processing page will be, which i just like to get the image's path(preferable path which link to the image file in cache) , and display it in a new window....
hope can get some help or recommendation to some useful articles ...
thx in advance

I used win32 application and wrote one WTL application file it shows error "WTL requires IE version 3.0 or higher" at compile time.
|
|
|
|
|
You need to set the macro '_WIN32_IE' to match the minimum version of Internet Explorer you're willing to support (this is basically for Common Controls support).
So, for IE3, put
#define _WIN32_IE 0x0300
in your stdafx.h, or for IE6, put
#define _WIN32_IE 0x0600
Note that there are also macros to set the OS level - see this page[^] for more details.

I inserted #define _WIN32_IE 0x0600 after compiling i got 6 error messages
First message "missing ';' before identifier 'lpnm'"
what i should do
|
|
|
|
|
I think you'll have to define WINVER and _WIN32_WINNT as well.

thank you for your reply
I used two header file and one cpp file. The files are following
// stdafx.h
#define STRICT
#define WIN32_LEAN_AND_MEAN
#define _WTL_USE_CSTRING
#define _WIN32_IE 0x0600
#include <atlbase.h> // base ATL classes
#include <atlapp.h> // base WTL classes
extern CAppModule _Module; // WTL version of CComModule
#include <atlwin.h> // ATL GUI classes
#include <atlframe.h> // WTL frame window classes
#include <atlmisc.h> // WTL utility classes like CString
#include <atlcrack.h> // WTL en
// MyWindow.h
class CMyWindow : public CFrameWindowImpl<cmywindow>
{
public:
DECLARE_FRAME_WND_CLASS(_T("First WTL window"), IDR_MAINFRAME);
BEGIN_MSG_MAP(CMyWindow)
CHAIN_MSG_MAP(CFrameWindowImpl<cmywindow>)
END_MSG_MAP()
};
// main.cpp:
#include "stdafx.h"
#include "MyWindow.h"
CAppModule _Module;
int APIENTRY WinMain ( HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow )
{
_Module.Init ( NULL, hInstance );
CMyWindow wndMain;
MSG msg;
// Create the main window
if ( NULL == wndMain.CreateEx() )
return 1; // Window creation failed
// Show the window
wndMain.ShowWindow ( nCmdShow );
wndMain.UpdateWindow();
// Standard Win32 message loop
while ( GetMessage ( &msg, NULL, 0, 0 ) > 0 )
{
TranslateMessage ( &msg );
DispatchMessage ( &msg );
}
_Module.Term();
return msg.wParam;
}
the above program only i got 6 errros
First error:
error C2146: syntax error : missing ';' before identifier 'lpnm'

Hi,
I want to share a CAtlFileMapping object between all simple ATL objects (between all instance of my COM Automation objects).
Basically, I want to load up a file control access to it so that multiple threads will not corrupt it trying to simulaneously write. The file should be accessible to all COM instances so that clients can invoke methods that modify this same file.
Pls advice me as to how I should go about doing this. I've programmed a lot in C++. But I'm completely new to ATL and COM.
Thanks in advace.

If you are using the single thread model, then COM will serialize all calls to the CAtlFileMapping object on a single thread, so that your object will only get called on one thread. Unless there's something different about the CAtlFileMapping object. It depends on how you CoCreate the CAtlFileMapping. Of course, if the CAtlFileMapping object is registered as "Both", and you are free threaded, you won't get that.
In that case, I would recommend you create a singleton object that all your COM Automation objects call into, and it uses critical sections to protect against calling into the CAtlFileMapping object.
Another solution might be for a custom class factory object. Have the CAtlFileMapping object as part of the class factory. Use CoGetClassObject to get the class factory, QI for your interface. You still need a critical section though, in the class factory to protect multiple access to the CAtlFileMapping.
Once you get past some of the COM/ATL'isms, its very similar to Win32/C++, just use a critical section to be on the safe side.

Hi everybody,
Does anybody know how to catch Microsoft word application events in a non MFC application (specifically WTL application) ?
thanks in advance,
Roozbeh
|
|
|
|
|
There's too much to specify in detail, but here goes...
Word events are specified as an interface that you (the client that wants to receive the events) have to implement. You tell Word about the interface implementation using Word's implementation of IConnectionPointContainer and IConnectionPoint, which is made simpler if using ATL through the function AtlAdvise.
These two links may help:
