Re: How to show and handle CFormView in ActiveX Joaquín M López Muñoz26-Mar-02 3:25 Joaquín M López Muñoz 26-Mar-02 3:25  If you do not intend to take advantage of SDI/MDI architecture, it's much easier to embed a CDialog-based object, just by specifying the ActiveX window as the parent when creating the dialog. Some CRect arithmetic could be needed too in the process of embedding. If you follow this approach, you can even get scroll bars without much effort.

I use the same procedure said all over this site. help Re: Finding tree root Tomasz Sowinski26-Mar-02 3:38 Tomasz Sowinski 26-Mar-02 3:38  Regarding (1): Handle WM_LBUTTONDOWN. Use CTreeCtrl::HitTest to get HTREEITEM. CTreeCtrl::GetRootItem returns root, so simple comparison of HTREEITEMS will answer your question. If you need to check if item is leaf, call CTreeCtrl::GetChildItem and pass clicked HTREEITEM - if it returns NULL, your item is a leaf.

In response to a button click on the dialog I need another dialog to popup. So far so good. I also need the text in an edit field in Dialog_1 to appear in an edit field in Dialog_2. In short, I need parameters to be passed from one window to another. How can I do this? With best regards, Sayan Mukherjee (sayanmukherjee@indiatimes.com) Re: Passing parameters to a Dialog Tomasz Sowinski26-Mar-02 2:36 Tomasz Sowinski 26-Mar-02 2:36  Add data members do dialog2 and initialize them before calling DoModal.

It was really helpful. A related question: In Windows SDK, each window has a place where a 32 bit pointer can be passed which is accessible from other windows. Using the heap, one can pack any amount of data and pass it. Is there any equivalent to that under MFC? I am sorry if the question is vague.

I'm not sure what you're referring to - WPARAM/LPARAM passed with messages or extra bytes per window which you request during class registration?

To the best of my knowledge, no. If you're using MFC, your Window subclassed object should have a data member that you can set and get. Of course, you could always access a CWnd derived class' public m_hWnd member, but that's nasty! /ravi "There is always one more bug..." http://www.ravib.com ravib@ravib.com Re: Passing parameters to a Dialog 26-Mar-02 2:43 26-Mar-02 2:43  hi, If you want a very stable mechanism,go for user defined messages. else get the data from one dialog and store it in mainframe and display it in the second dialog.Mainframe because it is present as long as the app is running;you may also use App class. hope it helped Rajendra Gowda Splitter Windows funbag26-Mar-02 2:23 funbag 26-Mar-02 2:23  I'm using a dynamic splitter window to display multiple views. I would like to create a window similar to the MS Outlook window, with one view on the LHS and two views on the RHS, one above the other. m_wndSplitter.Create(...) arguments insist that you create a number of rows and columns for the views. My question is, given that I must create a splitter window with 2 rows and 2 columns in order to achieve the desired effect, How do I hide/remove(?) the unwanted view? Many thanx funbag skydiving....if at first you don't succeed, you're fecked! Re: Splitter Windows Tomasz Sowinski26-Mar-02 2:34 Tomasz Sowinski 26-Mar-02 2:34  No, you achieve the Outlook-like layout with *two* splitters. First splitter splits window vertically. LHS is a view and RHS is another splitter which splits horizontally and hosts two views.

TLBS & Smart pointers bullshit ??
