I wouldn't do it there anyway. Dialog boxes are responsible for showing the data. The class or function that uses the dialog box is responsibe for giving it the data - the dialog should then set the controls to reflect that data - the calling function shouldn't really need any knowledge of how the data is shown to the user.

Combo boxes call malloc when they are created and contain pointers internally. Trying to call them before they are properly initialized will crash you.

When I test with ActiveX container tester mousemove can get the event when it is on the control. However, once the mouse is out of control, i don't get anything. Thank you for help Shin Re: mouseleave J. Dunlap18-Jul-03 21:51 J. Dunlap 18-Jul-03 21:51  You can use the TrackMouseEvent[^] API. It only works on Win98 or above, so if you need Win95 compatibility, you'll have to simulate MouseLeave using a timer: Start the timer when the mouse is first moved into the control. In the timerproc, use GetCursorPos to see if the cursor is outside of the window. If it is, fire a MouseLeave event, and stop the timer.

I wish I'd known about that. The number of times I've used SetCapture() and tested the location of the mouse cursor...

I have been looking for and they said I have to add #define _WIN32_WINNT 0x0400 this line. Still said TrackMouseEvent is not defined. So I added #include <winuser.h> the result is the same.... Why use Multi-thread Servers? Aidman18-Jul-03 13:25 Aidman 18-Jul-03 13:25  Hi, all I am planning on an http web server, and I have read some of the I/O completion and multithread server articles, but I really don’t understand why anyone would develop a multithread server? Would it just make it more difficult and slow, because of all the critical sections that have to be thread-safe? Why use worker threads that loops until a service is requested. Can’t you just use completion callback and windows message-based notification of network events to serve connected users? What’s the point of using multiple threads in a server? My server is going to run on older windows versions (95/98/ME) so I have to handle the worker threads (if I should use them) and connection sockets by my self, and of course the server has to support at least 500 user connections simultaneously. Anyway, I really don’t see any performance advantage by using multiple threads, so please tell me what I am missing because it seems like everyone is using it. Thanks in advance Aidman » over and out Re: Why use Multi-thread Servers?

Normally I use asynchronous socket, or if on NT based systems, IO Completion Ports. A limited number of threads is a good thing, it makes the application scale on multi-CPU computers, a single threaded server only uses a single CPU. And also, when a thread is "suspended" when waiting for IO like disk or network activity, it's good to have extra threads to keep the processor(s) working (if there is work to do, of course) - Anders Money talks, but all mine ever says is "Goodbye!" Re: Why use Multi-thread Servers? Tim Smith18-Jul-03 13:50 Tim Smith 18-Jul-03 13:50  Multiple threads buy you nothing as long as you don't have an extra CPU available. Oh and if you are never waiting on resources. Well, such as reading a file. Then multiple threads buy you everything. Tim Smith I'm going to patent thought. I have yet to see any prior art. Re: Why use Multi-thread Servers? Aidman18-Jul-03 14:55 Aidman 18-Jul-03 14:55  Thanks for your replys, but I am still a bit confused Are windows message-based notification of network events really slow? Can't they serve connected users, like reading from disk or sending data? If I should have say up to 100 users connected to my server simultaneously, how is the best way to serve them? worker threads, windows message-based notification or somthing else? And also, is it better to let threads loop until data is recieved or to use windows message-based notification?

Context help button for CPropertySheet haritadala18-Jul-03 11:32 haritadala 18-Jul-03 11:32  Hello all How to enable context sensitive help button(?) for CPropertySheet. I selected "Context Help" under Extended Styles for property sheet as well as property pages of that sheet. But when I ran the application the help button is not shown. If anyone knows how to enable it, pls help me. Thanks for your help. Hari.

So, for example you can remove the regular borders and caption and painting your own non-client area. For sure you must simulate the non-client events so your "skinned" app behaves like a regular app (e.g. moving the window around by clicking and holding the LButton on the caption,...). Looking at bit more at the screenshots, the background of the dialog and the buttons are also skinned. Skinning the background is easy and for the buttons you can use e.g. http://www.codeproject.com/buttonctrl/cxskinbutton.asp?target=cxskinbutton[^] In a few weeks, I will release a small shareware app, that also uses this owner drawn technique (combined with regions)... if you want to see a sample screenshot to see what can be done go to: http://www.oddgravity.de[^] (Sorry, until now I had no time for building my site ) Re: Flat dialog box Ryan Binns19-Jul-03 0:51 Ryan Binns 19-Jul-03 0:51  Windows won't do that for you. You will have to do all the drawing yourself.
