Hi,
the "& ~" construction means to remove the class style CS_DBLCLKS from the window. But this isn't necessarily the source of your problem. MSDN says the following:
>> If a window does not have the CS_DBLCLKS style, Windows sends
the following message sequence to the window: WM_LBUTTONDOWN,
WM_LBUTTONUP, WM_LBUTTONDOWN, and WM_LBUTTONUP.
>> If a window does have the CS_DBLCLKS style, Windows sends the
following message sequence: WM_LBUTTONDOWN, WM_LBUTTONUP,
WM_LBUTTONDBLCLK, and WM_LBUTTONUP. That is, the second
WM_LBUTTONDOWN message is replaced by a WM_LBUTTONDBLCLK
message.
So I guess the problem is located somewhere else.
regards,
mykel
If they give you lined paper, write the other way!

Yeah, I read the MSDN too... pretty friggin strange. Thanks for the explanation about & ~.

Beah this sucks and it's stupid. I can't beleive it. I just don't get those messages. Beah. I'm gonna put myself a hook there and story over. Nobody messes with hooks anyway, they rule. I don't like loading the system but a tiny HH_MOUSE on explorer.exe won't kill anybody :- D.
It's 3:18 AM and nobody answers... so I'll just do it like this since in about 12 hours I gotta release this stuff I'm working at. I'll check this topic after that... maybe some wise guy here has a clue why those stupid messages don't get in the WndProc that I made for the Systray Clock.

When the WM_NCHITTEST message (which always precedes the other mouse messages) is sent to the clock window, it returns the value HTTRANSPARENT, causing Windows to send the message to its parent, a window of class "TrayNotifyWnd". This also returns HTTRANSPARENT, so the message is sent to its parent, a window of class "Shell_TrayWnd". This window returns HTBORDER, indicating a click in the non-client area, so Windows then sends a WM_NCLBUTTONDOWN to the Shell_TrayWnd window - the child windows are treated as being transparent and do not receive the mouse click messages. The Shell_TrayWnd window is the one that actually receives and processes the mouse click messages.

Hi Ryan : ). Actually, I got that one subclassed too and I don't get nothing there either, beleive it or not. I solved my stuff with a mouse hook over explorer.exe but this isn't a solution I would accept if I would have alternatives. Unfortunately, I don't. Is it possible to make the TrayClockWClass accept mouse events?? Possibly chaning its class style ???? I don't know...

Are you checking for WM_NCLBUTTONDOWN messages? You won't get WM_LBUTTONDOWN messages because the clock window is setup to be in the non-client area of the tray window.
You could make the clock accept mouse events by overriding WM_NCHITTEST and return HTCLIENT from it, except then its standard functionality would not work.

I ain't getting no messages. Here's my check:
LRESULT CALLBACK WndProcTaskBar (HWND hwnd,UINT uMsg,WPARAM wParam,LPARAM lParam)<br />
{<br />
switch (wParam)
{ <br />
case WM_LBUTTONDOWN:<br />
case WM_LBUTTONUP:<br />
case WM_LBUTTONDBLCLK:<br />
case WM_NCLBUTTONDOWN:<br />
case WM_NCLBUTTONUP:<br />
..........
TaskBar being, of course, Shell_TrayWnd. Oh well, I guess I can play around with WM_NCHITTEST... thanks for the help once again, this ain't the first time you helped me :- ).

Just out of interest, what's your default case doing? Is it calling DefWindowProc() or CallWindowProc() with the previous (unsubclassed) window procedure? It should be doing the latter if you want to retain functionality.

All my cases (Systray Clock, TaskBar, Systray Window) are CallWindowProc with the handle returned when I subclassed via SetWindowLong....
Hm, as far as I see the hook isn't even as good as I thought. It has a few minor problems. But if I have no choice I'll keep it. I think I will soon try that HTCLIENT thingy that you mentioned. But right now I can't 'cause I gotta release on my head and just a few more hours to deliver it. (it's the second Beta of the freeware application I'm working on and I'm giving it to some more friends to use and report bugs ::- D ).

We just moved to Visual Studio 2005, and previously we were using a manifest file to make our vc6 apps look ala Windows Xp theme.
1. First of all, what the heck is this manifest file? Does it really do anything useful?
2. What is the correct way to use it for apps created in vc2005?
3. Is there any way to get menus to look half decent without integrating one of the xp-style menu implementations found here in CodeProject?
Cheers and thanks!

1 - as well as turning themes on, it specifies which versions of dlls your app uses.
2 - in your linker properties, you can get a manifest auto generated and embedded in your app
3 - Themes don't really do much for menus, they certainly don't add stuff like icons, which you could get from a library like Ultimate Toolbox, or possibly from samples on CP.

Christian, have any links for dealing with distrusting apps created in VS2005? Something like "Here dummy, it takes two minutes to set your app up for distribution"?
Any help is apprecated.
Thank You

Ok so i have my manifest file being generated to "$(IntDir)\$(TargetFileName).intermediate.manifest". How do I enable the themes? I imported this project from vc6, so it doesn't have it on by default.
Thanks

Note: Code above was to erase the window whenever the right button on the mouse is "clicked" doesn't work, any ideas? Sid Kraft

It will repaint the window. If you want to erase the current shape, you need to change ShapeKind first.

If I high-light some text in a window and right-click the mouse, there will be a popup menu with items like copy, cut, paste, etc.
If I know the handle of the window, how to get the handle of the popup menu? I know about the GetMenu API, does it do what I want?
This is for a non-MFC app. Please note that I don't want to create a new menu, just needs the handle of the existing popup menu.
Thanks.

Generally, the menu is created just before it is used and destroyed afterwards (most developers would do it this way), so you can't get a handle to it. Even if it was kept around, there is no API to get its handle because it is not a Windows function - the application takes care of creating and storing it, and just calls TrackPopupMenu() when necessary to display it.

What I want to do is adding some items to the menu, not replacing the menu. The application is not mine, I need to install a hook to get into the application. Currently I am trying other ways.
Thanks.

Then you might subclass the window and handle the WM_INITMENUPOPUP and, maybe, WM_RBUTTONUP messages.

How can I convert the standard MRU file list in menu File
to a popup submenu in menu File in a MDI application ?
Manosza.

Hi,
I want to add a password at a document level. I have an MDI app. My idea is to add a password variable, allow the user to create a password and archive it during serialization. Then, whenever the user opens that file, during the onopendocument process, I want to open a modal dialog box, get a password from the user, check it against the one that was saved during serialization and then decide to open the document or not. I tried doing domodal on a dialog box during serialization and during the onopendocument functions in CDocument, but neither would work, it kept throwing exceptions. Also, once I get the password and check it against the saved one, how can I abort the opening of the document? Any ideas on how I can do this? Thanks.

do all of this work before actually loading the file; you can do a lot of things before calling serialization.
you first do a "pre-read" (hidden from the user ) to see if the document is protected, then if it's not protected, you load it, if it's protected, read the password, compare it with the one in the document, if password is ok, read the file.
or simply ask for the password, then call the serialization and check there if the password is valid, and exit from the serialization.
