Re: Dialog Menu Question Michael Dunn5-Dec-01 16:18 Michael Dunn 5-Dec-01 16:18  Yes, just assign a menu to the dialog using the resource editor. --Mike-- http://home.inreach.com/mdunn/ Help! Help!

This server will need to be multithreaded. So questions. Does Winsock2 support threads? Some functions like WSAWaitForMultipleEvents and WSACreateEvent seems to 'be' threaded. Are there any examples of creating a socket server? Also interested in outright buying the sources for a professionaly built one.

It seems to have a problem attaching to the window during the CScrollBar.Create() method. The odd thing, all works fine in a dialog or CFormView class. I am quite stumped! If anyone can shed some light on my problem, I would be very greatfull! Thanks, James the invisible button --action thriller ahoodin5-Dec-01 7:12 ahoodin 5-Dec-01 7:12  MSVC 6.0 SP4 Windows 98 second edition On an application I am working on, the buttons on one property sheet dialog are disappearing intermittantly. Cancel, Apply and OK are like disappearing, for no apparent reason. If you click the spot where they would be, the BN_CLICKED message does infact work, and IDOK/IDCANCEL are sent, also DoDataExchange works too.

Does this happen immediately? Have you tested with Windows NT/2000? Regards, Alvaro Re: the invisible button --action thriller ahoodin6-Dec-01 10:57 ahoodin 6-Dec-01 10:57  Well, The application hasn't been tested on a Windows 2000/NT platform... Primarily because the drivers have all been written in vxd format for the hardware. I did however fire it up in Windows 2000 for a kick after you sent the note. The MFC portions of the application appear to work. The application needs an additional redraw occasionally. The Application skips through all hardware intializations as expected. The buttons that were problematic dissappeared on the 98 box over a period of a few weeks of constant running.

When I enter the dialog, the first radio button in the tab order is automatically checked. One of the screens has 3 radio buttons, and only 3. They are not grouped, nor do they have the tab order hint set. The dialog is a popup style modeless dialog. BOOL man2::OnInitDialog() { CDialog::OnInitDialog(); CRect r2; //the button is not set!!! main_dlg->GetDlgItem(IDC_GENERAL)->GetWindowRect(&r2);// get size IDC_GENERAL // Set prog window right on top of IDC_GENERAL area of screen, and show it SetParent( main_dlg->GetDlgItem(IDC_GENERAL)); // IDC_GENERAL set 2 parent window //the button is set, for some unknow reason the first push button in the // tab order has been activated!!! SetWindowPos( &main_dlg->wndTop,0,0,r2.Width(), r2.Height(), SWP_SHOWWINDOW); return TRUE; // return TRUE unless you set the focus to a control } This does not cause any problems if the first tab order item is a static text box rather then a control. Currently I fix this problem in this way, however I am looking for answers on this one. I am not happy with this Hack. I don't think the answer is as easy as tab order or group setting. It is not the default behavior of the radiobutton. ahoodin Whenever you have truth it must be given with Love, or the Message and the Messenger will be rejected. -- Mahatma Ghandi Disconnect Rickard Andersson205-Dec-01 6:32 Rickard Andersson20 5-Dec-01 6:32  I want to make a internet connection checker app that disconnect the connection if it has past i.e 1 hour.

However when using a modem dialup to the internet. I usually use TAPI with the lineDrop method to drop a call. Of course you need to have opened the device through TAPI first. Michael DLL & Resources #realJSOP5-Dec-01 5:14 #realJSOP 5-Dec-01 5:14  I'm working on a DLL that initially did not have MFC support, and it also uses the WINAPI ENTRYPOINT construct for allowing access to it's functionality. I changed the project settings to support MFC, and I know how to add a dialog box, but it doesn't come up like a normal app does. Instead, it saves it in a (resource?) "script". Further, ClassWizard is not available, even after the dialog resource is created in the project. Can I just cut and paste MFC dialog box code into the class I create?

Using the resource editor, I added the Context Help extended style. The help button "Question Mark" shows up on dialog's title bar but nothing happens when I click on it. If I don't add minimize and maximize button to the title bar, the help button works fine. I am using VC++ 6.0 on win 2000. Any help/suggestion will be appreciated.

Thanks for answering. The problem is I don't want to derive my Dialog from a class other than CDialog (I know that the given class derives from CDialog). As this seems to be a little tricky, I changed my mind. Now I just want to add a button on the title bar. When the user clicks on it, I open my own html help. Thanks again. Have a good day.

Re: non client area & context help Jon Hulatt5-Dec-01 5:50 Jon Hulatt 5-Dec-01 5:50  from visual c++ help: Context help Includes a question mark in the title bar of the window. When the user clicks the question mark, the cursor changes to a question mark with a pointer. If the user then clicks a child window, the child receives a WM_HELP message. The child window should pass the message to the parent window procedure, which should call the WinHelp function using the HELP_WM_HELP command. The Help application displays a pop-up window that typically contains help for the child window. Sorry to dissapoint you all with my lack of a witty or poignant signature. Re: non client area & context help Djibril5-Dec-01 7:56 Djibril 5-Dec-01 7:56  Thanks but I know this.

Re: non client area & context help Jon Hulatt5-Dec-01 22:15 Jon Hulatt 5-Dec-01 22:15  I don't think you can rate posts on here. Instead, you should send a check to me at the following address:- ) If you really want the help button and min&max buttons, you're going to have to paint the nonclient area yourself. Handle WM_NCPAINT, and draw the title bar yourself. Of course, you'll have to also handle some other WM_NC* messages in order to notice when user clicks your button.

Chambers5-Dec-01 4:50 Chambers 5-Dec-01 4:50  Hi all, this is the last part of my project before I start the write up, and I`m finding it a bit frustrating. All I want is control that acts like a grid. That is, I want a big square on my square which is divided up into columns and rows and holds UINT's. This control must be dynamic, i.e. when I click on the adjust IncCol/IncRow CSpin thingy (a problem Ravi helped me out on, see below), the number of columns/rows will increase *within* the square as necessary (the current fields will have to change size accordingly to accomodate the new row/column). Delphi has something called a TStringList, which is pretty much what I need, except it uses strings instead of UINT's. I have tried using many edit boxes, and then creating them/deleteing them as necessary, but the code is woefully complicated. I just want a nice simple solution (I don`t need it to change colour etc. etc.) to represent a resizable grid of integers, which can be read from and directly edited to much the same fields of a database. If anyone could help, or give me some ideas, I would well appreciate it, could I get this crappy project done and go out there and get a job. Thanks All, Alan. P.S. I have had a look at Chris's grid control, and it is too heavy duty for what I need. From my understanding it seems to draw the grid manually, which would mean me spending a lot of time on this, which is exactly what I don`t want to do.
