sorry, I tried to look for a place where i can specify imports under project setting, but not with much luck.

can u be a bit more specific about how to import a library?

SetLayeredWindowAttributes is only supported on Windows 2000 or greater therefore you will not see it on an older operating system. If you are building for windows 2000 or greater, you will need to define _WIN32_WINNT = 0x0500, otherwise the preproocessor will remove all of the API definitions that are only available on Windows 2000 and above. Coincidentally this will cause runtime error if you run one of these programs on a system that has an older DLL version.

As far as linking a library to your project, you can do it the way that you specified, or you can go to the linker tab of your projects settings, and add the name of the lib to your project. However most likely you are already linking user32.lib into your program if your program already has a user interface.

QUESTION 1:

#define _WIN32_WINNT = 0x0500

and why? It's not in the api documentation??

QUESTION 2:

What do I type in project>setting>"link" tab>"object/library module" ??

"./user32.lib"

Is this right? Do I have to include quotation mark?

QUESTION 3: I downloaded a sample that uses LoadLibrary.

# define LWA_COLORKEY 1
# define LWA_ALPHA 2
# define WS_EX_LAYERED 0x80000

HWND hWnd=this->m_hWnd;

typedef DWORD (WINAPI *PSLWA)(HWND, DWORD, BYTE, DWORD);

PSLWA pSetLayeredWindowAttributes;

HMODULE hDLL = LoadLibrary ("user32");
pSetLayeredWindowAttributes = (PSLWA) GetProcAddress(hDLL,"SetLayeredWindowAttributes");

if (pSetLayeredWindowAttributes != NULL) {
pSetLayeredWindowAttributes(this->m_hWnd, RGB(255,255,255), 100, LWA_COLORKEY|LWA_ALPHA);
}

It claims that the code wont crash even if run on Win98 or platform that doesnt support SetLayeredWindowAttributes and transparency.

U think it's a good idea?

btw, i've got the code working via LoadLibrary. it's more versatile too.

i'm still interested to see how to statically linked library to your module via project>setting>link tab

Auto Resized Objects in CFormView :: MFC

Hi.

Okay. I would like to ask a question that I know is quite popular among MFC Windows developers. It holds the key to some very cool GUI features when implemented correctly.

I would like to know, How do you resize and reposition objects inside of a CFormView (apply to resizable dialog box as well) as the user resizes the main frame? For example, given there is an edit view inside a formview. As the user resizes the frame, I would like to the expand or contract the edit box. Another example in the same scenario is repositioning the entire edit box or a button according to how the user resizes the formview.

Thanks,
Kuphryn

The frame/view receive a WM_SIZE message, you handle it, and use MoveWindow on each controls ( objects ) to their new position and size, or look around here on codeproject, people already did some auto-position/size classes that do that automatically.

Personally, I use resizing sparingly, I try to build my UI in a way that the default size is good for the data to be inputed or viewed. resizing doesn't give "more" to the user.

Just out of curiousity, what is the difference between MoveWindow() and SetWindowPos()?

Kuphryn

Re: Auto Resized Objects in CFormView :: MFC

Maximilien29-Oct-02 2:27

Maximilien

29-Oct-02 2:27

MoveWindow sends other messages, WM_WINDOWPOSCHANGING, WM_WINDOWPOSCHANGED, WM_MOVE, WM_SIZE, and WM_NCCALCSIZE. SetWindowPos does not.

I prefer MoveWindow because I can handle those messages so I can manage the sizing myself of the child windows.

Question for the IE internals gurus

Hi guys:

Does anyone know where IE stores the information in the History popup window, what the format of that file is, and under what conditions it's possible to change it. (or is it?) Basically I want to change what's displayed in-place... I was thinking of just subclassing that window, but a cleaner way would be to change the file itself... any ideas?

Thanx Smile | :)

No guru here, it's newbie stuff. The history is of course a tree folder with internet shortcuts. To get it without hardcoding a path (changing depending on the OS), use the shell API ::SHGetFolderPath with CSIDL_HISTORY as parameter.

How low can you go ?

If you want manipulate the history, you should use the IUrlHistory[^] interface to do it properly.

Hi again:

Thanks for the responses. A couple questions:

1. I need this to work for IE5, and according to MSDN the IUrlHistory interfaces require 5.5 minimum.

2. The History "folder" is kind of weird -- I have a strong suspicition it's actually a file, shown as a folder through the use of shell extensions, or something like that. In other words, I don't think I can just enum files inside that folder, looking for ones I want to change. Am I wrong?

Any other ideas?

Thanks,
Gene

Replacing GINA

I'm working on a GINA replacement, because we need to do some custom log on of the users.
I have one major problem that I can't find any solutions for.

When the user is logged on, the start-menu is, err..., not exactly disabled but it's acting very strage.
Fucus is not folloving the mouse, and it don't respond to mouse clicks.

Anyone got an idea?

I have been searching google and found other people with the same problem, but not any solutions. Frown | :(

Are you sure you setup proper security descriptors for the WinSta0 and WinSta0/Default windowstation/desktop objects?

Seems that the user account the shell process is running under has not the proper access rights to create menus.

Deranged CHtmlCtrl

I'm using the CHtmlCtrl from this article http://www.microsoft.com/msj/0100/c++/c++0100.asp[^] so I can put the CHtmlView in my dialog based app and it works fine except for one problem. When I load my app the CHtmlCtrl sits in a state of disarray, what I mean is the ctrl just flashes bars of the form color and doesn't load anything until I click a menu item. Once I do that the page loads and all is well until the CHtmlCtrl gets covered by another window then the whole things starts again. Here's the code I'm using to paint the window:

CWnd* pParent = GetParent ();

CRect rect;
pParent->GetWindowRect (&rect);
pParent->ScreenToClient (&rect);
MoveWindow (&rect, TRUE);

I want the CHtmlCtrl to be resized to the size of the window that's why I'm using the code above. If I take out the code above then the CHtmlCtrl isn't updated until a menu item is clicked. I'm completely baffled as to what the menu items are calling besides the OnPaint handler that is making the page load correctly. Any help would be very much appreciated. If you want anymore code or information just let me know.

Thanks in advance.

are you moving the window inside the OnPaint handler?

try putting that MoveWindow outsite the OnPaint handler. otherwise, you're probably causing paint messages from inside your OnPaint handler. while it's not recursive, it's more painting than you need.
