WS_CAPTION style defines whether your window has a title bar or not. If you remove this style from the style definition flags used with 'CreateWindow' call, the window will not have a title bar.
Remember, that the system menu flag (WS_SYSMENU) is dependant on the WS_CAPTION flag. Having the first without the latter may cause an assertion.

Hi,
I used CFile object.I included afx.h as header.I am getting the following error in calling the function CallWindowProc and SetWindowLong .I did not include windows.h because I am getting error if I include both windows.h and afx.h
d:\test_plugins\gen_minisdk\trayctl.cpp(144) : error C2664: 'CallWindowProcA' : cannot convert parameter 1 from 'void *' to 'long (__stdcall *)(struct HWND__ *,unsigned int,unsigned int,long)'
Conversion from 'void*' to pointer to non-'void' requires an explicit cast
d:\test_plugins\gen_minisdk\trayctl.cpp(169) : error C2664: 'SetWindowLongA' : cannot convert parameter 3 from 'long (__stdcall *)(struct HWND__ *,unsigned int,unsigned int,long)' to 'long'
This conversion requires a reinterpret_cast, a C-style cast or function-style cast

Explain your steps in more detail. The errors you posted and the CFile object are not related in any way.
If you are trying to use MFC without the project wizards, then in addition to including the afx.h header, you must link with the appropriate MFC library.
If you are trying to create a Winamp plugin, like it seems, then remember that in the XP world, you cannot subclass a window by replacing window procedures anymore. At least so it says in the MSDN.
The example provided by NullSoft may no longer function properly. I suggest you either contact them or spend some time experimenting. However, what I do know, like I stated, is that these errors have nothing to do with the CFile object. They might pop up because of the MFC header, but in that case, you'll just need to re-check your function calls and remember the linkages.

I have an application where I need to have a grid, or something similar to an Excel spreadsheet. I inserted the Microsoft Spreadsheet 9.0 into my application, and I think I can make this do what I need it to if I knew how to control this thing. Has anybody used this before, or know of some good publications that I can figure out how to control it.
For example, I want to be able to set the column widths, and variable types...I'd even like to be able to make some columns read-only if possible. I'm just not figuring this out by looking at the function lists.
Thank you for your help.

i wish to run my .exe program in a pc that unfortunately is nt installed with visual c++ so is there anyway i can get it run?

For that you need to make a installer for yuor application, and install all the neccessary dlls that ur applications requires. To find out that use depends.exe to determine on what all dlls ur application depends on.

Hello
Please run the dependency walker under Ms VC Tools
If you do not have it search the microsoft website and I "think" you may download one from there.
Most VC functions may be installed in one component.
You may download this from http://sourceforge.net/project/showfiles.php?group_id=21558
It is at the very bottom of the page. Take extreme care (check for os before you install them.) can really screw xp 2000 and some other editions up.
Shold only be needed in NT 4. NT3. 95 some editions of 98. Every time you have to bloat your install files say "THANKS BILL" really loud.
Best Wishes and Happy Holiday's,

WCHAR m_wszTitle[51];
How can i do this ?

wcscpy(m_wszTitle, CT2CW(strCString), 51)

Talk to the hand!

I get :
'CT2CW' : undeclared identifier !!!
i use vc++6.0
i also can't find CT2CW in the MSDN
|
|
|
|
|
|
Try:
USES_CONVERSION
wcscpy(m_wszTitle, CT2CW(strCString), 51)

I dunno, but maybe it would go better for you if you asked a question in your header. Most of us are also over 12, and so calling yourself h4ek4z does not help, it's bloody annoying to look at and gives an image of you as a 10 year old script kid.
Finding out what a users password is also does not sound like a sociable thing to be wanting to do.

hi there...
i have been writing a simple image processing aplication under visual c++ .net, using the CImage class. but now i have to change it to be compiled under visual c++ 6 (without using gdi plus libraries...). is there any class like CImage that works under vc6?? i mean, i need a functions to open a bitmap file, to save it, to get the width, height, the pixel values, to construct one from parameters (array of pixel values, width, height, bits per pixel, just like the CImage class)...
could anyone give me a hand on that?? does it exist anything on vc6 like this??

Yes, it's called GDI+. You just need an up to date SDK in order to use it. Read my GDI+ articles, they were written with VC6.

Hello guys,
I created sub (child) dialogs on a parent dialog, using the class provided in this place:
http://www.codeproject.com/dialog/childdlg.asp?target=child%7Cdialog
It all works well, except I am not sure how to get all the child dialogs to interact with each other or with the parent dialog. Basically, I have a main child dialog displayed with the parent's OnInitDialog, and every button pressed on this child dialog should/will replace it with another corresponding (sub)child dialog (having being assigned them to the same GroupBox in the parent dialog). The problem is the buttons in all child dialogs do not seem to do anything, pressing them will not trigger any belonging functions at all. Only the buttons in parent dialog operate properly and can use them to switch between the child dialogs to show in the GroupBox.
Did anyone have experience with this?
Thanks alot

Let's say my application has a pointer to a CDialog derived class and I create some modeless dialogs.(More than one!). My question is how to destroy all of them - myPointer->DestroyWindow() - for the last created one and after that how to redirect the pointer to the rest of the dialogs in order to destroy all of them?
|

You can use DestroyWindow() to delete the underlying MFC windows handle. Obviously, if you use this on a dialog this will delete all the underlying child handles associated with that dialog box. Another method is to use PostMessage(WM_CLOSE, 0, 0), which is the method I prefer. To destroy a chain of dialog associated with each other you could try SendMessageToSiblings(WM_CLOSE). This will filter through a dialog box chain sending the message to each sibling (To be honst I've never used this method so I don't know if it will work).
If you wanted to get all object orientated about it you could look at using the composite design pattern. This design pattern is used to forming complex tree structures and works brillantly for distributing messages across its tree structure.

OK, found it.
You need to call SetButtonStyle with TBBS_CHECKBOX | TBBS_CHECKGROUP style.

How to Send an event from an Automation Server to its Client?
Hello,
I wrote an Automation Server. I know how a client can get/set properties belonging to a server, but I am not sure of the right way a Server can fire events to its client.
I tried this solution: (It does actually work, but maybe this solution is "naive" and will not work in some cases)
1) The client sends (once for good), the handle of its main window (or its thread ID.
2) When the server wants to fire an event to the client, it calls either ::SendMessage or ::PostThreadMessage with an agreed message number.
Is there a better solution?
I read about IConnectionPoint. Is this relevant to my problem? Can you send me a link to an example?
Many Thanks,
Mike
