Hi !
I have an explorer-like app, where I'm trying to implement a drag'n drop feature : I want the user being able to select an item in the list of the right view, and drop it in a branch of the tree in the left view.
According to MSDN, I created an COleDropTarget in my left view class, and registered it. Now, I have to implement a source on my right view, but I don't really understands what the MSDN explains.
Anyone could help me ?
Thank you in advance !

GetUserName returns the current user or you want to know the users that are using your resources?

Check in one of my Articles here . The Article is for NT but easyly you can make some changes for use the function that enum the user over win 95 or win 98...
You need to use the NetWkstaUserEnum function, but the problem is that any of thouse functions are no compatible whit win95....
Regards!!!;)

The idea of using Add-ins is realy cool. However, there's no ready made functionality to support it in MFC (as far as I know). So, does anyone happens to know where could I find a ready-made code framework for an application which knows how to load and use Add-ins ?

This link for an artical of mine shows the basics of how to use DLL add-in documents from a DLL. Its a good starting point for what you want to do.
http://www.codeproject.com/docview/docviewfromdll.asp
I dont know of an artical which covers add-ins in more depth as these add-in API's tend to be application specific.

I need to implement support for the Visual Styles of XP in some application. It's not based on MFC, just pure win32 api is used. The main window of this application has a toolbar which is "hand made" too.
The problem is that Visual Styles API does not draw the bitmap of the toolbutton or makes it terrrible - draws the bitmap without tacking in account the transparency color...
Please help, here's that simplified code (for better readability) for each button on the toolbar:
HTHEME hTheme = GetToolbarHTheme(hwnd);
BITMAP bm;
COLORREF cl = MGetBitmapInfo(hBitmap, bm, -1, -1); // gets the dimentions and the transparency color of the bitmap
HIMAGELIST himl = ImageList_Create(
bm.bmWidth, bm.bmHeight, ILC_COLORDDB|ILC_MASK, 0, 2);
int i = ImageList_AddMasked(himl, hBitmap, cl);
DrawThemeBackground(hTheme, hdc, 1, state, &rect, 0);
DrawThemeIcon(hTheme, hdc, 1, state, (LPRECT)&rc (LPRECT)ptbi, himl, i);
ImageList_Destroy(himl);
CloseThemeData(hTheme);
when I remove "ILC_MASK" then the bitmaps are drawn in th black rectangles or
else nothing appeares

I have to assume that the function "GetToolbarHTheme" is something that you wrote, because that is not a part of the Visual Theme API. I am on a Windows 2000 computer at the moment, so I have no way if the following code will work, but the way I would approach the problem is something like this:
PAINTSTRUCT ps;
BeginPaint( hWnd, &ps );
HTHEME hTheme = OpenThemeData( hWnd, L"TOOLBAR" );
DrawThemeParentBackground( hWnd, ps.hdc, ps.rcPaint );
DrawThemeBackground( hTheme, ps.hdc, TP_BUTTON, TS_NORMAL, &ps.rcPaint, 0 );
DrawThemeIcon( hTheme, rc.hdc, TP_BUTTON, TS_NORMAL, &ps.rcPaint, himl, i );
EndPaint( hWnd, &ps );
I would also recommend creating the image list once, instead of creating it and destroying it every time you draw a button. That will allow you to preload the images, create different lists for different button states, etc. Also, you should use the defined constants (TP_BUTTON, etc.) instead of hard-coding the numbers into your function calls.
If at all possible, use the new Windows XP true-color icons. These icons have 32-bits per pixel, with 8-bits per channel, including the alpha channel. You can specify any pixel to be transparent this way. Image lists do support this in XP, so there's no reason not to use them.

Thank you for your answer, Paul.
But I wanted to ask something different.
This function
DrawThemeIcon( hTheme, rc.hdc, TP_BUTTON, TS_NORMAL, &ps.rcPaint, himl, i );
behaves wrong in my hands  it draws nothing or bitmaps without transparency at all
and my question is what am I doing wrong with that image list or "DrawThemeIcon"

Then, I think you will probably want to investigate the new true-color icons that were introduced with Windows XP. Not only are they true color, but they support a full 8-bit alpha channel for transparancy. An image list composed of these may work better, but I do not know for sure.

Why when I click VK_DOWN or VK_UP ... (when my control has focus - control derived from CWnd). Control lost focus and next control get focus ?
Control doest never reveive VK_DOWN
Creating code :
dlg_table.Create(NULL,"Table",WS_CHILD | WS_VISIBLE, CRect(0,0,210,20),this,1001);
|
|
|
|
|
That window needs to respond to the WM_GETDLGCODE message. The DLGC_WANTARROWS flag will let the dialog message loop know you want the arrow keys.

I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk?

Hi,
I've created my ATL object, with one dual interface, and one custom interface, I have no problem accessing to the dual one, but to the custo, I cannot have access ( in the MFC application, using Smart pointers).
Does Smart pointer didn´t work with custom interfaces ?????
Thanks, Bye !

They do work - what kind of Smart Pointers do you use?
(ComPtr, _com_ptr_t, or the MFC stuff? I usually use #import and the the _com_ptr_t ones - they are great...)

Hi !
I´m using the "#import" thing, and CComPtr, it´s quite amazing because I can declare the pointer, and the compiler won´t complain, but when I try to get my interface, it returns NULL, altough I've declared it in the interface map.
Thanks for your help, Bye !

Whar error code is returned?
Is it an out-of-apartment component? In this case, the Proxy/Stub DLL might be missing / not registered.
