Re: about ToolBar BigMouth22-Dec-01 21:35 BigMouth 22-Dec-01 21:35  - Thanks, Christian pal! - I do not know why the method sometimes does not run stablly. Sometimes it runs ok, sometimes it does not run ok. - Can you tell me why it happens? Need I refresh something manually? - Best regards, BigMouth Re: about ToolBar Christian Graus23-Dec-01 10:20 Christian Graus 23-Dec-01 10:20  You need to run it when CMainFrame has been constructed and not destroyed. When does it crash ? You can do this: CMainframe * pMain = dynamic_cast<cmainframe*>(AfxGetMainWnd()); if (pMain) { // use it here } This is how C++ does run time type information, and although it should *always* work in this case, it gives us a chance to catch if it doesn't. Whenever you request a pointer you should check it first, even if it's just with ASSERT.

I think your codes are added to the function OnCreate, so it is sure that the CMainFrame has been constructed. - So I think there is no need to test whether the "pMain" is NULL. IMHO - Can you help? - Merry Christmas, BigMouth Dialog Box Problem mvworld11-Dec-01 22:42 mvworld 11-Dec-01 22:42  I have a dialog based application which the user accesses through a password. Now there are 2 categories of users and depending on the login and password the application has to display 2 different user screens. How do I do this? Also when I first wrote this application I had just one user in mind so all the code is present in the dialog class CApplicationDlg. Is it possible for me to hide all the controls on this dialog box and create a new user screen on the same dialog box when the 2nd user type logs in? Thanks Mike. Re: Dialog Box Problem Joaquín M López Muñoz12-Dec-01 1:28 Joaquín M López Muñoz 12-Dec-01 1:28  Well, I guess the simplest way to get this done, given the original design of your project, is as follows: Create two sets of controls for each user profile and merge them into the only dialog resource. You'll end up with a mess of overlapping controls, so you might want to do the work separately in auxiliary dialog resources and then copy and paste to the final destination. On the process some controls will be shared (i.e., they exist for both user profiles), keep that in mind and do not duplicate them. Have all the controls hidden by default. If you select Test on the Resource menu, the dialog should appear empty. Have two static arrays defined for your CDialog class, each specifying the IDs of the controls that should appear for the corresponding user profile. Add a variable to the constructor of your CDialog class indicating the user profile. In OninitDialog you just have to walk thorugh the appropriate array of control IDs and call GetDlgItem(id)->ShowWindow(SW_SHOW). Hope this helps. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: Dialog Box Problem mvworld12-Dec-01 1:35 mvworld 12-Dec-01 1:35  I figured that out thanks. But the problem now is that I need a menu bar for one user category and no menu for the other user category. By default the dialog box loads a menu bar, and I want to remove it when the user 2 enters. So I did the following CMenu* menu = GetSystemMenu(TRUE); menu->DestroyMenu(); But the program crashes! What do I do? Thanks, Mike Re: Dialog Box Problem Joaquín M López Muñoz12-Dec-01 4:42 Joaquín M López Muñoz 12-Dec-01 4:42  Well, maybe you can do it the other way around: by default have no menu in your dialog, and set it when needed with SetMenu.

Does anyone know how to make an aplication that do not have a rectangular window ... ( ex. diferent skin for MediaPlayer in WinXP ) Bye, BogdanO ...the night is long ... but not long enought to do some real coding ... Re: change window shape Joaquín M López Muñoz11-Dec-01 22:54 Joaquín M López Muñoz 11-Dec-01 22:54  Lots of information on the net about how to do it. Check for instance How to Create Non-rectangular Windows on the Xploiter website. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: change window shape Ernest Laurentin12-Dec-01 3:54 Ernest Laurentin 12-Dec-01 3:54  - Just call SetWindowRgn() for your window - Use Jean-Edouard L. Robert source code to create a region from a bitmap Codeguru's Bitmap Bitmap to RGN UNICODE and ifstream 11-Dec-01 22:01 11-Dec-01 22:01  Hi, this should be quite an easy fix, I just don't know how. I'm writing an internationalised program that has to store text in a file. I cannot for the life of me get the stl ifstream extractor to compile for UNICODE... i.e. these do not work TCHAR t[1024]; stream.getline(t,1024,'\n'); ... TCHAR t[1024]; stream >> t; ... std::wstring w; stream >> w; but if I convert TCHAR to char the damn thing compiles. What am I missing? Surely something in the STL templates allow the reading of a double byte character from the stream. Any pointers appreciated. Matthew Re: UNICODE and ifstream Joaquín M López Muñoz11-Dec-01 22:17 Joaquín M López Muñoz 11-Dec-01 22:17  Use wifstream, which is the instantiation of basic_ifstream for wchar_t (instead of char). Better yet, define a macro of your own for selecting ifstream/wifstream the way TCHAR does. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: UNICODE and ifstream 11-Dec-01 22:36 11-Dec-01 22:36  wicked, thanks. I never even knew wifstream was there. I am very pleased indeed. did I say thanks? Matthew Showing window contents while dragging.. 11-Dec-01 20:01 11-Dec-01 20:01  I work in Windows 9x and Window 2000 environment, and I am developing a Win32/MFC application. I got a question about the one of the "monitor properies" in Windows. Remember ? When you are in Windows desktop, right click the mouse, and a pop-up menu shows. The last one is "Properties". And when you choose the "Property", there are 6 tabs. The 4th or 5th tab is "Effect". And, there is an item: "Show window contents while dragging". Now, if I want to set this property ("Show window contents while dragging") in my win32/MFC application, is there any win32 or MFC API I can use in my program to do this ? Thanks for your help ! Re: Showing window contents while dragging.. Erik Funkenbusch11-Dec-01 21:56 Erik Funkenbusch 11-Dec-01 21:56  It's just a registry setting, therefore you use the registry API. -- Where are we going? And why am I in this handbasket? Re: Showing window contents while dragging.. 11-Dec-01 22:11 11-Dec-01 22:11  >>It's just a registry setting, therefore you use the >>registry API. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Which registry API ? Could you explain more detail ? Thanks a lot ! Re: Showing window contents while dragging.. 11-Dec-01 22:22 11-Dec-01 22:22  I found an API in MSDN: SystemParametersInfo(..), but I still can not find any parameter that looks like the property(show window contents while dragging).. You change this Registry key... Atul Dharne11-Dec-01 23:26 Atul Dharne 11-Dec-01 23:26  The Registry Key which controls show contents of window while dragging is Key: [HKEY_CURRENT_USER\Control Panel\Desktop] Name: DragFullWindows Type: REG_SZ (String Value) Value: (0=disable, 1=enable) You can use API RegOpenKey, RegCreateKey... in your app to check if it exists. If so check the value and toggle it to your needs. If not create it. Atul Dharne #include "codeproject_users_experience_" using namespace codeproject; Re: Showing window contents while dragging.. Michael Dunn12-Dec-01 9:03 Michael Dunn 12-Dec-01 9:03  Call SystemParametersInfo(): SystemParametersInfo ( SPI_SETDRAGFULLWINDOWS, TRUE, 0, FALSE ); Change TRUE to FALSE to turn it off.

Now, having no access to the server, for the sake of argument, can someone point me in the right direction on how to get the info on who has a given file open from the server thru code? Thx Mark Re: Who has file open on server Erik Funkenbusch11-Dec-01 22:01 Erik Funkenbusch 11-Dec-01 22:01  If you have no access to the server, there is no way to know who has it open. Only the server knows that information. -- Where are we going? And why am I in this handbasket? Re: Who has file open on server Bill Wilson12-Dec-01 13:26 Bill Wilson 12-Dec-01 13:26  Check out the WMI stuff here and on MSDN. Several of the WMI examples deal with network drives and open files. Hope this helps, Bill Re: Who has file open on server WalthamstowBoyInSydney12-Dec-01 16:44 WalthamstowBoyInSydney 12-Dec-01 16:44  Thx for the reply, I can't find anything here on codeproject to do with WMI and the SDK I just downloaded makes me realise how 'stoopid' I am Dont suppose I can prevail upon you to point me in a slightly more confined direction? Mark Re: Who has file open on server Bill Wilson13-Dec-01 5:58 Bill Wilson 13-Dec-01 5:58  Sorry, I meant codeguru. Here is a good starting point. http://www.codeguru.com/system/WMI_using.html This is the Microsoft tutorial. http://msdn.microsoft.com/downloads/default.asp?URL=/code/sample.asp?url=/msdn-files/027/001/574/msdncompositedoc.xml The WMI SDK also contains many more examples. I had pretty goo luck using Google to find info. WMI is a client server type arrangement. The server software is called a provider. Once you know what providers you need to use, you can do more specific searches on google. My own project used the Win32_Processor provider. I put Win32_Processor and Loadpercentage into a Google.com query and got lots of links, some of which were useful. Hope this helps, Bill CString::Replace in C++ without MFC 11-Dec-01 15:14 11-Dec-01 15:14  Can anybody either a) provide me with a C\C++ function that mimicks CString::Replace in functionality, or b) explain in detail (i.e. step by step) how to do this myself? I have tried for ages, but can;t get anything that works. Thank you, Russell McCurly Hobbiest Programmer
