std::string id=(char *)(_bstr_t)m_pRecordSet->GetCollect(L"id");

Hi I think that GetCollect returns a variant, and in case of
NULL values, this variant has a VT type of VT_NULL,you
could check for it.

Steps :
- get the current document (IHTMLDocument2)

- then get the document.forms collection

- for each IHTMLFormElement, retrieve the target IHTMLInputElement edit box by going through the .elements collection (edit box are usually identified by their names : IHTMLInputElement::get_name(BSTR* p);)

- set/get the appropriate value with IHTMLInputElement::put_value(BSTR v);

And I swallow a small raisin.

Hi Mr Rodriguez,
Thanks for your reply. But I guess this method is a bit tedious and also it won't solve all my purpose. So I have figured out a different approach. Can u help me in modifying the url to navigate. I have sinked the BeforNavigate2 event in my CHtmlview class. I have read in an article that I can modify the navigation by sinking event BeforeNavigate2. I have to modify the url. Pls help me with code fragment to achieve the same. I ahve seen an article in MSDN periodicals but it has a vb example. Pls help me
Regards,

CComboBox Edit Mode

I want a ComboBox that doesn't accept the user typing in some data.

I'm pretty sure this is just a flag to be set on creation, WM_EX_NOINPUT or something but I can't remember which one.

Can anyone help?

Niek Albers' CHoverButton[^] provides tooltips for a CButton-derived class. Maybe you can cut & paste the code to your control.

Set the notify style of the picture control. You can then add a tool tip for the control by doing th following:

call EnableToolTips()

in messge map

ON_NOTIFY_EX(TTN_NEEDTEXT, 0, OnToolTipNotify)

in header file

afx_msg BOOL OnToolTipNotify(UINT id, NMHDR * pNMHDR, LRESULT * pResult);

in .cpp file

BOOL CSamplesFloat::OnToolTipNotify(UINT /*id*/, NMHDR *pNMHDR, LRESULT * /*pResult*/)
{
TOOLTIPTEXT *pTTT = (TOOLTIPTEXT *)pNMHDR;

if (pTTT->uFlags & TTF_IDISHWND)
{
// idFrom is actually the HWND of the tool
UINT nID = ::GetDlgCtrlID((HWND)pNMHDR->idFrom);

pTTT->lpszText = "";

switch (nID)
{
case IDC_PICTURE_CONTROL :
pTTT->lpszText = "My picture control" ;
break ;
case IDC_METHODDETAILS :
pTTT->lpszText = "The selected methods details" ;
break ;
}

if (pTTT->lpszText[0] != '\0')
{
pTTT->hinst = AfxGetResourceHandle();
return TRUE ;
}
}
return FALSE ;
}

In fact this can add a tolltip for any control in a dialog/view/floating window etc that you do this for.

How to prevent a child window from move from its original position.

Good day everyone,

I would like to know how to prevent a child window from moving from its original position when interecting with a mouse/keyboard. A good example of this would be Microsoft Visual Basic (6.0) form editor. The form in the designer window allows the user to change the width or height of the window but not the X/Y psoition at 0,0 or close to it.

Re: How to prevent a child window from move from its original position.

Actualy tried that and it still allowed it to move. What I did try and seem to work is handling the WM_WINDOWPOSCHANGING and provided the X and Y attibutes a constant value.

Thanks for your reply.

Create the menu, open dialog template in the resource editor and select menu from dropdown list on 'General' page.

or you can create the menu manually and call SetMenu() from within the dialogs OnInitDialog() handler.

this is useful if you intend to dynamically modify the top level menu items.

ps. whenever you call SetMenu(), msdn says you must follow up with a call to DrawMenuBar()

To the best of my knowledge, it is the bandwidth of your connection that is limiting the number of threads that are able to download data (actually, all of them are trying, so you can expect all the threads to complete their operations as the first ones stop consuming bandwidth). To prove this point, try using a server in your own LAN (which will provide much more bandwidth) or even within your local machine.

Toolbar resize

I am writting some code to add new buttons in a toolbar at runtime.
My problem:
When i create a new button, the toolbar is not big enough and the last one is no visible anymore. If i move the toolbar to another position in the window (manually, with the mouse), it resize itself automatically and all the buttons become visible again.
How to get the toolbar with the right size automatically , just after adding a new button ?
I try adding Invalidate() and AutoResize(), but it doesn't work.

void CMyAppView::OnAddNewModule() 
{
CToolBarCtrl* pToolBarCtrl;
pToolBarCtrl = &(((CMainFrame*)GetParentFrame())->GetToolbar())->GetToolBarCtrl();

TBBUTTON tbButton;
tbButton.iBitmap = pToolBarCtrl->AddBitmap(1, IDB_MY_RUNTIME_ID);
tbButton.idCommand = MY_NEW_COMMAND;
tbButton.fsState = TBSTATE_ENABLED;
tbButton.fsStyle = TBSTYLE_BUTTON;
tbButton.dwData = NULL;
tbButton.iString = NULL;

if (tbButton.iBitmap==-1)
TRACE("I couldn't load the button image");

if (!pToolBarCtrl->InsertButton(1, &tbButton))
TRACE("I couldn't create the new button");

pToolBarCtrl->AutoSize();
}

Thanks !

PD: I use ON_COMMAND_RANGE handler, to catch the new event with my predefined ID, thanks Saurwein Wink | ;)

try calling ((CMainFrame*)GetParentFrame())->RecalcLayout();

i'm not sure that it _will_ work but CFrameWnd uses it alot internally when positioning controlbars.

Filemapping

If we create a shared memory zone with CreateFileMapping(...), we have to close it with UnMapViewOfFile(...) and CloseHandle(...).

My question is this: Is the memory released properly doing just that? Or do I have to take some further action before closing the memory handle?
