Any suggestions to overcome both of these problems? How can I get Taskbar notification because my application is running and also one DialogBox is getting displayed? Thanks, -- Sumit Sumit Pandya modified 1-Aug-19 21:02pm. Re: Main Dialog and Taskbar 567890123417-Jan-02 3:53 5678901234 17-Jan-02 3:53  Don't do this in OnInitDialog. In such cases I set timer in OnIntiDialog to some small time interval and continue operations in OnTimer. Dialog in this case is already active and visible. Re: Main Dialog and Taskbar User 2674017-Jan-02 4:21 User 26740 17-Jan-02 4:21  Hi, But At the same time I donot want to display my main DialogBox until user respond to my shown DialogBox. Thankx for taking time to write-in again. -- Sumit Sumit Pandya modified 1-Aug-19 21:02pm. Napster-like media player Jon Newman17-Jan-02 3:40 Jon Newman 17-Jan-02 3:40  Does anyone know how to create a media player for mp3/wma that doesnt need windows media player? Napster used a mp3 dll file. do i just wrap it or do i need to write somehting else? .NET or not .NET? MFC is the question...... Re: Napster-like media player Christian Graus17-Jan-02 9:39 Christian Graus 17-Jan-02 9:39  I presume you mean a winamp type player ? There's one on CP - search for MPEG.

This input can be stored in registry or if user selects "Open" then it again retrieved from registry. This Dialog box contains EditBox and Radio Button controls. My problem is when user select "Ok" the user must be prompted to store settings or not. I wanted this prompt only if user has made some changes in existing retrieved profile. So this decision is only Applicable if "Open" while for "New" this prompt will always be there. I can assure this change in Editbox but not in the RadioButton group For Editbox I'm doing following ... ... ... m_ctrlLdapCredentials.GetLine(0, Buffer); bNoSavePrompt &= (m_ldapCredentials.CompareNoCase(Buffer) == 0); ... ... ... How I'll come to know that If any of setting in radio button group controls has been changed? Do I need to remove that group then what is alternative to that? GetCheck() is not answer in case of group. Thanks. -- Sumit Sumit Pandya modified 1-Aug-19 21:02pm. Re: Control Change Notification Mustafa Demirhan17-Jan-02 3:13 Mustafa Demirhan 17-Jan-02 3:13  Create a variable (an UINT) for that radio group using Class Wizard. After this you can compare its previous value (which is an integer, that contains the index of the selected radio button) with this new value. Or if you choose the hard way, you can use ((CButton*)GetDlgItem(ID_MYRADIOBUTTON))->GetCheck () method on all of your radio buttons and look if it is changed or not.

I have created a toolbar with only text on buttons. I would like to add the mnemonics on it. Adding '&' to the button text before setting does not work. Thanks, Sujata. Re: adding mnemonics on toolbar buttons Anna-Jayne Metcalfe17-Jan-02 3:05 Anna-Jayne Metcalfe 17-Jan-02 3:05  Would I be right in thinking that what you really want is a toolbar with images and captions? If so, I have some code you can take a look at to see how it's done. Go to http://www.resorg.co.uk/whats_new.html, download the source code and take a look at the class for the main toolbar - it should be self explanatory FYI the shortcut keys are normally handled by the menu, not the toolbar, so if you have a menu command for each toolbar button with the '&' in the right place it should work.

(with Service Pack 5) 1) Is there a way of not stepping into functions such as CString during a debug session. I'm sure I read on CP how to do this, but I cannot find that article again. 2) When running Visual C++ on a Win2K machine, sometimes when pressing F5 to build and run, VC will cause my machine to reboot. Any ideas on how to fix this?

As for second question, I'm running VC6 on Win2k too, and have no problems with it.. So it is not Win2k, but something installed on your machine Philip Patrick "Two beer or not two beer?"

What I would like is to be able to step over CString::Mid()() but into foo().

Anyways I don't see big deal by pressing F11 - Shift+F11 - F11... and u are inside your function Philip Patrick "Two beer or not two beer?"

But if it was as intelligent as you want it to be, it'd do you out of a job! Sorry to dissapoint you all with my lack of a witty or poignant signature.

Paresh Solanki A Completly Random Ordering Never Yields Meaning CWinThread derived worker-thread 16-Jan-02 22:17 16-Jan-02 22:17  What do you think is the better way to implement a object-oriented worker-th? passing "this" as a LPVOID-param to a static member-function, which uses "this" to access member-data/functions dedicated to thread-operation and call the static member-function with AfxBeginThread, or subclass CWinThread like that: BOOL CWinThreadDerived::InitInstance() { // loop but check for kill notification while(WaitForSingleObject(m_hEventKill, 0) == WAIT_TIMEOUT) { WorkToBeDone(); } return FALSE; // avoid message loop by returning FALSE } I prefer the CWinThread-derived way, because it's comfortable to implement, but a programming-professional told me THAT I shouldn't do so, but not WHY. What do you think? Re: CWinThread derived worker-thread Mustafa Demirhan17-Jan-02 0:50 Mustafa Demirhan 17-Jan-02 0:50  If want to have an OO solution, you should definitely use CWinThread-derived way. I am also using CWinThread-derived way in my applications and I have not heard any problems from my customers yet. But some multi-thread related classes in MFC have really serious bugs. For example, using CEvent class is not advised. As I have heard, it causes the application crash in some situations. I also saw this warning in a book from Microsoft Press(I could not remember the name right now). Kind regards Mustafa Demirhan http://www.macroangel.com Sonork ID 100.9935:zoltrix Re: CWinThread derived worker-thread 18-Jan-02 2:56 18-Jan-02 2:56  Could you explain how you use it? Remember: I want a Message-loop-LESS worker-thread. I poll for a shutdown-event in InitInstance() and while it's unsignaled a Work()-function is executed. Is it the way to go? Yeah I heard about those troubles with MFC-syncs, so I use API-calls to sync my threads, Thanx for your Re, Flo! Re: CWinThread derived worker-thread Mustafa Demirhan18-Jan-02 3:59 Mustafa Demirhan 18-Jan-02 3:59  AFAIK, a worker thread is always message-loopless. Otherwise it is called user interface threads. In InitInstance() method, you can do the initializations. You should have a method called int Run() which will be called automatically when the thread is initialized. The thread should do its job in this method. CMyThread *pThread = new CMyThread (); pThread->CreateThread (); This creates the thread, and starts running it. If you want it to be started later, CreateThread takes a parameter for this (CREATE_SUSPENDED or something like this. I could not remember it right now ) Have a look at the following pages http://www.codeproject.com/threads/cthread.asp -> This really a very good example! http://www.codeproject.com/threads/usingworkerthreads.asp Hope this helps.

I see! when I override Run and don't care THERE for the Messages, it already has no message-loop, am I right? Is Run called once or continuosly? thx Flo Re: CWinThread derived worker-thread Mustafa Demirhan19-Jan-02 10:27 Mustafa Demirhan 19-Jan-02 10:27  Yes you are. Run is called only once!
