Hi,
How do I get flat scrollbars in a CTreeCtrl?
For at CListCtrl it's done by using SetExtendedStyle(), but I can't find any similiar member function in CTreeCtrl.

I'm afraid you can't do that. There's no TVS_xxx style for setting flat scrollbars. Even if you use InitializeFlatSB, FlatSB_ShowScrollBar and FlatSB_SetScrollProp with CTreeCtrl's HWND, all you'll get will be flat scrollbar that doesn't scroll the window contents.

I would really like to recursively call the OnPrint function but everytime I try, it's catastrophically not working. I am doing something wrong or is this just not possible?
Sincerely,

Recursively calling OnPrint is rare and most likely not needed. Write your own Print() method and call it. Otherwise, study the OnPrint() method flow-you can completely replace it without any problem if it does not meet your needs.
The framework calls the OnPrint() after a lot of preparations.

Hello,
I have an ActiveX control and it receives the WM_MOUSEWHEEL message in both VB and VC applications.
Now, I am convering the client window of the ActiveX control with a CWnd (say view). This child view receives all messages except the WM_MOUSEWHEEL messages in VC. However, in VB applications the view receives the WM_MOUSEWHEEL all right.
What is the problem here? and why the difference in VC and VB applications?
Best regards,
Paul.

We are creating an app using Win32 where the user is able to define the GUI through a Python console. In order to do this, I have created a dialog, which will be invisible, and am making everything else a child of this dialog, so we don't get a gazillion things on the task bar. This works fine for the console dialog, it comes up as a seperate window and comes to the foreground when I click on the invisible window's task bar button. But when I make my windows WS_CHILD and children of this dialog, they live on the dialog, instead of being windows in their own right, able to wander the desktop freely, but without a task bar button ( which is the whole point ). I can see how this behaviour is to be expected, the question is, how do I get the behaviour I want ?
Is there a way to just hide from the taskbar ? I will then have to iterate through the windows when the parent window is chosen and show them all I guess, or is there a better way ?

Hello Christian,
You better state the specification more clearly. What are the child makeup? dialogs? controls?
Best regards,
Paul.

Like I said, they are Windows, as in I register a window class and create a new window. I've found I can get these windows not to have a task bar button if I make them tool windows, but I don't want to *do* that. I want normal windows, with a normal system menu ( close/maximise/minimise ) but nothing on the taskbar. My console is a dialog, and creating dialogs works fine and dandy with WS_CHILD, but not creating a normal Window. My top parent window is a dialog, and I've made it one pixel wide and at -20, -20, on the basis that multi monitor users are unlikely to find it there, and I need to make it visible or I get the same old problem ( nothing on the taskbar ), but this window exsits solely to be a parent to all my other windows, of which I could have as many as the user decides to create at runtime through the Pyton console.

Okay, how about the WS_POPUP/WS_POPUPWINDOW?

Either of those styles kills my window by losing my caption bar and/or my border. Neither of them removes the button for that window in the task bar.
I am able to create the windows, and the windows look exactly as I want them to, but the problem is that WS_EX_APPWINDOW looks right but puts a button in the task bar, WS_EX_TOOLWINDOW doesn't give me a taskbar button, but it also doesn't give me minimise/maximise buttons or a normal size caption bar.

Well, you might have to experiment a bit more. If all fails, the obvious solution is to do the custom caption-if it is MFC application then there are so many codes out there, if pure SDK/Win32 I have ported the Paul Dislacia's code (MSJ) for my Win32 framework I was not able to complete.
Also, if you are not in harry, I could take a look at the problem too.

Paul.

Christian,
Have had to something very similar, and so I looked up a few details that I'd forgotten. The basic info is from the MSJ November 97 "Q&A:Win32" column by Jeff Richter. I think this should do what you want, although I remember having to 'fiddle' a little to get exactly the effect I was after.
>>
Q I'm writing a wizard-like application that leads the user through some setup tasks. Since I spawn this application from my main application, I don't want the system's taskbar to show a button for this window. I've performed many experiments and I can't seem to figure out what rules the taskbar uses to determine whether it should show a button for a window. What are the rules?
A The rules the taskbar uses to decide whether a button should be shown for a window are really quite simple, but are not well documented. When you create a window, the taskbar examines the window's extended style to see if either the WS_EX_APPWINDOW (defined as 0x00040000) or WS_EX_TOOLWINDOW (defined as 0x00000080) style is turned on. If WS_EX_APPWINDOW is turned on, the taskbar shows a button for the window, and if WS_EX_ TOOLWINDOW is turned on, the taskbar does not show a button for the window. You should never create a window that has both of these extended styles.
You can create a window that doesn't have either of these styles. If a window has neither style, the taskbar decides to create a button if the window is unowned and does not create a button if the window is owned.
One final note: before making any of the above tests, the taskbar first checks to see if a window has the standard WS_VISIBLE window style turned on. If this style bit is off, the window is hidden; the taskbar never shows a button for a hidden window. Only if the WS_VISIBLE style bit is on will the taskbar check the WS_EX_APPWINDOW, WS_ EX_TOOLWINDOW, and window ownership information.

Thank you both - I'd say I need to not set WS_EXxxxWINDOW, hopefully as my Window is owned ( I presume this means it has a parent that is not NULL ), setting WS_CAPTION | WS_SYSMENU etc. will fix the problem.

Maybe I'm reading into this wrong but don't you actually need a window that ISN'T a child window but that doesn't appear on the taskbar (if it's a child window of the dialog then it's position is confined within the dialog just like what you've got).

Precisely. However, the way it works at the moment, I use GetParent() to find out if a window recieving focus is part of the application, so I want it to be a child, but not contained as a child of a dialog (obviously) would be. My main window probably should be a window, but for some reason creating an initial window class always failed until I made it a dialog.

Hi,
I want to add an autocompletion feature to my CFileEditCtrl control using the SHAutoComplete() API. I have two questions:
1.) When I use SHACF_FILESYSTEM flag, the list contains virtual folders (Control Panel, Printers etc.). Is it possible to eliminate the virtual folders from the list?
2.) Once I call SHAutoComplete() on my CFileEditCtrl, is it possible to remove (disable) the autocomplete feature?
Thanks for your time.

Skip it. I don't think SHAutoComplete() will work for me.
- No way to show just folders if FEC_FOLDER style is used
- No way to autoselect multiple files.
I will just have to attempt to roll my own autocomplete feature.

Hey Guys
Can anyone tell me what this message means "ASN1 Unexpected end of file"
and this is produced by the CryptVerifyDetachedMessageSignature

Hey all!
I recently stumbled upon a REALLY WEIRD bug - and I'm totally stuck!
Bug description: I send EM_GETTEXTEX message to a rich edit control, and get an empty string - even though there is definitely a string there - it even returns the correct length of the string when I send an EM_GETTEXTLENGTHEX message!
I compile the code in 4 modes:
1. Deubg build, an EXE application
2. Debug build, an ActiveX application
3. Release build, an EXE application
4. Release build, an ActiveX application.
I compiled using both VC++ 7 and VC++ 6 (no SP), and used Windows 2000 (no SP) + IE6 for the ActiveX.
I was also able to occasionally reproduce the bug in a Debug build when I used NuMega BoundsChecker.
And here is the weirdest part:
I have some code that looks more or less like this:
1. Get string from Rich Edit control and display it
2. Get string from Rich Edit control and display it
3. char *sz = new char [1]
Now, in the ActiveX Release build - the previous code displayed two empty strings. When I removed line 3 - the code worked. Or maybe it was the other way around... But anyway, that was the situation.
I thought about subclassing the Rich Edit control, causing the program to crash when the EM_GETTEXTEX message is received, and then follow the Rich Edit Control assembly code and see what's going inside there - but it seems too painful!
Does anyone have any constructive idea?? (other than "go drink your troubles away", please)
Thanks!

Tomasz was nice enough to tell me where the data for the Summary page resided. Can someone tell me direct me to some code that manipulates it?
"Where in the world is the data persisted?
If you're using W2K, it's stored in a 'Document Summary Info' stream. Alternate file streams are a NTFS-only feature. Write something at a 'Summary' page, then drag the file to A: - you'll see the warning about data loss; only the main stream will be copied to floppy.

I swear I saw mention of using streams in a recent MSDN mag, like maybe 2 or 3 issues ago. Basically, when opening the file, you add a colon and the stream name to the end of the path, for example "D:\readme.exe:STREAMNAME".
Where in the world is the data persisted?
In the file system.

I created DLL that contain a class for using by clients.
And it is right.
But my clients say they can't use with this class because they works in Delphi and impossible create object from my class in it.
-----------------------------------------------------------
I want to know :
Is it right ?
How can I to create in my DLL global function that will create object from the class in this DLL and will use its member functions
for clients.
----------------------------------------------
This func have to get some parametrs from the clients and to return parameter. as so:
BYTE* func(int a, char* str)
{
CMyClass obj;
..............
..............
if ( obj.DoModal()== 0)
return ----
return ------------
} 
-------------------------------------------
My project is in: MFC AppWizard (dll) -> MFC Extension DLL
Please Help me !!!!!

in general, only MFC clients can use MFC extension DLLs.
if you want to export functions to non-MFC clients, you will need to use plain C interfaces on all of your exported functions.

I inserted my this project to regular dll by the wizard.
I have a dialog class and I writed export global function so:

MyDialog dlg;
dlg.DoModal();
return dlg.num;
}
/********************************************************/
But when I test it with client program it dont show me the dialog.
