your thread function is a static function i.e. it does not operate on a specific object and does not have a 'this' pointer.
Invalidate() is a non-static method i.e. it requires an object to operate on. you need to pass an object pointer through to the thread (typically as the thread parameter) and then use that to call Invalidate() i.e.
<br />
CWnd* pThis = (CWnd*) threadParam ; <br />
pThis->Invalidate( FALSE ) ; <br />

It isn't a good idea to try and use CWnd objects in worker threads, because they don't appear in the handle map for the worker thread. This leads to all sorts of problems. Better to just use the HWND (Window Handle).

If you have HWND via GetSafeHwnd or m_hWnd been passed to your function,
just call api's directly ::InvalidateRect(hwnd,NULL,FALSE);

Hello all, does anyone here know of any tools that could port MFC codes or libraries to MacOS X Jaguar?
Some URLs would be great. 
Thank you

For serious xplatform GUI development, I recommend Qt[^]. Not cheap, but worth it imho.

I have been messing around with wxWindows. In my opinion its a great library. the syntax is very similar to MFC, so MFC coders will take to it right away. Best of all its.. FREE. Most of my MFC apps I have successfully converted to wxWindows, and with very little effort have compiled them under Win32, Mac, and Linux. It might be worth a try.

Yes, I've heard good things about wxWindows too, although I haven't used it personally.

It is a good tools indeed but so sad that we had started our project in MFC 
but still, a big thanks

If your application is already coded in MFC, too bad, you will need to restructurize everything, extract all GUI stuff from the core code.
The 2 models are quite different, and the UI toolkit work differently; not just the UI, but also the file system.
Depending on the size of the application, it can be a huge task; once you start doing it, you can't really stop, it's like a one way tunnel, you cannot back away without loosing a ton of money and time.
I used to work for a company that had an MFC application (graphical application, lots of UI )that needed to run on Mac OS X, and we figured it would take about 1 year with 6/7 programmers to do it, part of it was that we decided to use Apple's Objective-C language instead of straight C++ for the UI (Cocoa).

with wxWindows this is not entirely true. I have ported several of my MFC apps to wxWindows with realitive ease. I would say at least a little over half of my code was as simple as changing "C"xxx to "wx"xxx. Most of the wxWindows library is structured after MFC; so most of the syntax is the same. The only problem you have, is if your code contains lot of OS specefic code or API calls.

I had tried the WxWindows.
But I have this little problem here.
LINK : fatal error LNK1104: cannot open file "wxxrcd.lib"
This was shown during compilation. I do not know where to get this lib. Other png.lib and etc are ok except this one.
Any idea?
|
|
|
|
|
I think i found it already.
thank you. quite cool.
|
|
|
|
|
I don't know if you have solved this problem, but make sure that you compile all of the wxWindows library.
I have never had that problem.

there are a couple of articles here on how to do that - search for "smtp". there's also a public-domain library called blat.

is it possible to embed CSplitterWnd object in the CView class as opposed to embedding it (as commonly) in CMDIChildWnd class? if so, what are the steps to do it? Thanks.

It is possible. Make the splitter window a member of the view, and in the OnCreate() message handler, create the splitter via CreateStatic() or CreateDynamic(), and then add the child views.

It goes the other way, the splitter window contains a view in each pane.

Hi all
void Dump( ON_TextLog& ) const;
const int sss;
what is the difference that a "Const" is at front and rare?
Can someone give me a example?
Thanks
|
|
|
|
|
When used in a class, a const at the end of a method says that the method will not modify the object. This is important for a few reasons.
1. The compiler can verify that the method doesn't actually modify the object.
2. The compiler can verify that the method doesn't call another method that might modify the object.
3. If you have a "const" pointer to an object, you can only invoke const methods on that object. (oh, mutate I think too).

hi,
Here is my code under development.
------------------
HWND hToolTip;
TOOLINFO ti;
char buf[1024]
// hListView is a HWND of my listview
hToolTip = (HWND)SendMessage(hListView, LVM_GETTOOLTIPS, NULL, NULL);
// initialize the ti parameters
ti.cbSize = sizeof(TOOLINFO);
ti.hwnd = hToolTip;
ti.lpszText = buf;
ti.uId = (UINT)0;
// test 1
SendMessage(hToolTip, TTM_SETDELAYTIME, (WPARAM)TTDT_INITIAL, (LPARAM)(INT)MAKELONG(0,0));
// test 2
SendMessage(hToolTip, TTM_SETTIPBKCOLOR, (WPARAM)0x0000ffff, NULL);
// test 3
SendMessage(hToolTip, TTM_GETTEXT, NULL, (LPARAM)&ti);
AfxMessageBox(ti.lpszText);
------------------
In my code, the test 1 and 2 work correctly.
I can change the delaytime and the background color of the tooltip text.
I think that the hListView and hToolTip were well defined.
But I don't know why test 3 doesn't work. The contents of ti.lpszText is null even
when the tooltip text is not null.
Actually, I don't know how to set the ti parameters to retrieve the tooltip text
of N-th item of a ListView.
Any comments about this problem will be appreciated.
Thanks.

Hi, there.
What kind of compression libraries are there?
Can you draw the outline, relationship between them or history.
For example, gzip and zlib, gzip and pkzip, and so on.
It's me, nine. nine for you.
|
|
|
|

I will take a stab at this.
ARC -> PKZIP
PKZIP -> ZLIB
PKZIP -> WINZIP
ZLIB -> GZIP

Hi, is there a way to set a status bar invisible? Or a way to make a status bar that is not in the OnCreate() function?
Also, what's the easiest way to grey out a menu option? The menu is already set on the CFrameWnd. Thanks.
Daniel R

I haven' tried this, but can you hide the status bar by simplying changing the style bits - i.e. m_wndStatusBar.ModifyStyle( WS_VISIBLE, 0 );
Menu commands can have update handlers which allow them to be enabled/disabled. The easiest way to add them is to use Class Wizard to select a command id, and then add a handler for COMMAND_UPDATE_UI. These handler methods take a single parameter which is a CCmdUI object.
You can do something like this:
void CMainFrame::OnMyCommandUpdateUI(CCmdUI* pCmdUI)
{
pCmdUI->Enable( FALSE );
}
