Under Samples\Multimedia\DirectShow\Editing. It's called StillCap and illustrates movie and still capture. Derek Lakin. I wish I was what I thought I was when I wished I was what I am.

I just hacked the example I mentioned to get it to behave how I wanted (but I didn't change the video capture functionality). Derek Lakin.

I need help to achieve a project at work. My app is a MFC dialog based. I need to access variables and control between 3 modeless dialog. How can I do that. I've tried everything I know. I have already a lot of work done in both 3 dialogs... Let me explain what I've done. - I have 3 templates : IDD_MainDlg , IDD_Dialog1 , IDD_Dialog2 - IDD_MainDlg's class is CMainDlg (Created with the wizard at startup...) - IDD_Dialog1's class is CDialog1 and then IDD_Dialog2 is CDialog2. - I've declared : CDialog1 m_Dialog1; CDialog2 m_Dialog2; inside the CMainDlg header file. - I've created : m_Dialog1.Create(IDD_Dialog1,this); m_Dialog2.Create(IDD_Dialog2,this); m_Dialog1.ShowWindow(SW_SHOW); m_Dialog2.ShowWindow(SW_SHOW); inside the OnInitDialog() of CMainDlg; Let say that I have a CSliderCtrl object called 'm_Slider' declared inside the CDialog2 header file. When I'm in CMainDlg, I can access this variable by typing m_Dialog2.m_Slider without problem or error. Where I'm confused is when I'm inside CDialog1 and want to access m_Slider. This is the 'best one' of all codes I've tried : CDialog2* pWnd; CMainDlg pdlg; pWnd = &pdlg.m_Dialog2; pWnd->m_Slider.SetPos(0); I always get an assertion error. When debugging it always say that there is no handle _AFXCMN_INLINE void CSliderCtrl::SetPos(int nPos) { ASSERT(::IsWindow(m_hWnd)); ::SendMessage(m_hWnd, TBM_SETPOS, TRUE, nPos); } (m_hWnd is always 0x00000000 ) What can I do to get all the things working well ?!?!?! I have a lot of data to pass between theses three dialogs so... Best regards, Brind If coding looks like drugs... I should go on therapy... Re: Need Help with Dialogs Tom Archer30-Apr-02 22:33 Tom Archer 30-Apr-02 22:33  You're code is not working because the window has not been created yet. Always keep in mind that just because you create an instance of an MFC class such as CDialog (or a derived class), the encapsulated window isn't actually there until you tell the class to create it. With regards to communicating data between these various dialogs, there several ways to achieve this. If you're simply trying to get initialization data to one dialog from another, you can change the constructor to accept this information. Then in the dialog's constructor, you save this information in member variables and finally use it to init the dialog's controls in either the OnInitDialog or DoDataExchange function.

Re: Need Help with Dialogs Brind_Foin1-May-02 3:13 Brind_Foin 1-May-02 3:13  Hi Tom , I don't understand what you said when you tell that 'the encapsulated window isn't actually there until you tell the class to create it'. Is this because I create my window inside the main window or what? Would you supply me a small example that will point me in the right direction. Also, my datas to be communicated aren't only to be passed at initialisation of the dialog, they are to be communicated all the time until I stop the app. Im newbie in C++ so, there's a lot of thing that confuse me!! Thanks, Brind If coding looks like drugs... I should go on therapy... Re: Need Help with Dialogs Tom Archer1-May-02 3:23 Tom Archer 1-May-02 3:23  When you instantiate a CDialog, you don't have a window yet. You won't until you specifically tell the class to create its underlying window. In the case of a modal dialog this is done via DoModal. In the case of a modeless dialog, this is done via Create or CreateIndirect. In you situation, you're referring to controls on a dialog that haven't been created because their containing window (the dialog) hasn't been created. Therefore, you'll need to move that code using one of the techniques I described.

CFtpConnection::SetCurrentDirectory() Tony Fontenot30-Apr-02 20:16 Tony Fontenot 30-Apr-02 20:16  What is this function used for? No seriously, I have been playing around with CFtpConnection, specifically PutFile, and I have found that i need to specify exacly where the file should be placed on the server. I tried to use SetCurrentDirectory but to no avail. The functions returns success but when I just put the file name in PutFile it transfers it to the root. To me SetCurrentDirectory should let me put just the file name(no path) in PutFile. So my question is. Am I doing it wrong and SetCurrentDirectory should work the way I want it to, or am I suck with PutFile with the Path\FileName.

Re: CFtpConnection::SetCurrentDirectory() Joao Vaz30-Apr-02 21:24 Joao Vaz 30-Apr-02 21:24  It worked perfectly for me, you tried using GetCurrentDirectory and then set the path relatively with SetCurrentDirectory ? What was the error that GetLastError() reports ? x = GetLastError(); Better put the variable x on the watch window with the modifier hr like this: x,hr what the error says ?

Swinefeaster30-Apr-02 20:02 Swinefeaster 30-Apr-02 20:02  You need to create a CFormView-derived class via the ClassWizard for each dialog resource that you defined. Then you need to call CFrameWnd::CreateView() for each view. Then use CFrameWnd::SetActiveView() to switch between them. cheers, swinefeaster Check out Aephid Photokeeper, the powerful digital photo album solution at www.aephid.com. Re: CFormView question ...
