[wtl]Making toolbars like in Winrar

6-Mar-05 1:33

sorry i'm used to mfc in vc++ development and new to atl...

how to us embed a menu in a dialog that derived from CAxDialogImpl?

if it was a dialog that derived from Cdialog, we can do this by just

<br />
CMenu menu1;<br />
menu1.LoadMenu(IDR_MENU1);<br />
SetMenu(&menu1);<br />

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.

Need help with linker errors

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.

code to retrieve window xp's user name

Re: code to retrieve window xp's user name

1-Mar-05 3:53

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...

Michael Dunn1-Mar-05 7:48

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.

Re: code to retrieve window xp's user name

1-Mar-05 20:59

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... Smile | :)

Get the Platform SDK. (FAQ link)[^]

And there have to be dozens of examples of using SHGetFolderPath(), search here or with Google.

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 ...

WTL shows compile time error

inbakumar.G27-Feb-05 19:08

27-Feb-05 19:08

I used win32 application and wrote one WTL application file it shows error "WTL requires IE version 3.0 or higher" at compile time.

Cry | :((

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

Stuart Dootson27-Feb-05 22:26

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
