Finding tree root 26-Mar-02 3:04 26-Mar-02 3:04  hi, 1.how to find weather the item clicked is a root or leaf in a tree. 2.should the menu resource be initialised or something before loading it to diaplay popup menu because I get run time error saying the handle is null. 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 ?? Braulio Dez26-Mar-02 1:03 Braulio Dez 26-Mar-02 1:03  Hi, I have created one ActiveX Full control, and I'm using it through a TLB in my MFC client App, I need to get the interface to IDataObject, but it didn´t work out, I have tried two ways, the "smart one" ( pBaseMeta is an smart pointer to my control BSREPORTCTRLSLib::IBsMetafilePtr pBaseMeta): IDataObjectPtr DataObj; DataObj = pBaseMeta; The good old one...: IUnknown *pUnk = NULL; IDataObject *pDataObj = NULL; pBaseMeta.QueryInterface(IID_IUnknown, (void **)pUnk); pUnk->QueryInterface(IID_IDataObject, (void **)pDataObj); Here even a QI to IUnknown returns me NULL ! Should I forget TLBS and all that wrappers and directyle use CLSID's... and GUIDS and AddRef and..., is so sh*tty this ? Thanks in advance Braulio Re: TLBS & Smart pointers bullshit ?? Tomasz Sowinski26-Mar-02 1:14 Tomasz Sowinski 26-Mar-02 1:14  Use debugger to step into pBaseMeta.QueryInterface - you'll be able to check what's exactly going on. Maybe smart pointer isn't initialized correctly. Tomasz Sowinski -- http://www.shooltz.com ** If you're going to rape, pillage and burn, be sure to do things in that order. **
