Re: CHtmlEditCtrl Control Creation Failed

Ummm. It's strange that the dtor is protected, but nevertheless you're doing it wrong, since in this case the control should be dynamically allocated:

BOOL CHTMLCDlg::OnInitDialog()
{
CDialog::OnInitDialog();
 
CHtmlEditCtrl*  m_HtmlEdit=new CHtmlEditCtrl();
m_HtmlEdit->Create ("",0, CRect (0,0,100,100), this, 1);
....

I don't know about your CHtmlEditCtrl (???) but I've tried this with CHtmlView and it works very nice. CHtmlView (like all CView's has the constructor protected)

//in your OnInitDialog

CHtmlView *pView ;
CRuntimeClass *pRtClass = RUNTIME_CLASS(CHtmlView);
pView = (CHtmlView *) pRtClass->CreateObject();
pView->Create(NULL, NULL, WS_VISIBLE | WS_CHILD, rct, this, IDC_STATIC_CTRL);

pView->Navigate2(_T("www.microsoft.com"));

How can I edit a ListItem in a MFC CListCtrl. I know that i should place a Edit-Box. But on which position?
How can I get the Position for the EditBox?

No, you don't create your own edit box. Handle the LVN_BEGINLABELEDIT and LVN_ENDLABELEDIT notifications.

What do you mean edit an item? Do you mean change an item if the user clicks on it?

For example, if the user double clicks an item, you could create a dialog box with the item's current data and allow the user to change it.

I am having a problem with getting an animation to be displayed with a transparent background. I have a C++ based application (no MFC) which has a dialog that I want to display an animation on. I am doing something similar to the Windows dialog when a copy operation is occuring. However, I have an animation of a PC and a watch communicating. My background color in the AVI file is white (RGB 255, 255, 255). Here is the code I use in my WM_INITDIALOG message:

hAnim = CreateAnimationCtrl(hDlg, IDC_ANIMATE);
Animate_Play(hAnim, 0, -1, -1);
hdc = GetDC(GetDlgItem(hDlg, IDC_ANIMATE));
SetBkColor(hdc, RGB(255, 255, 255));

The IDC_ANIMATE Id is the animation control on the dialog. Here is the code for the CreateAnimationCtrl function:

HWND CreateAnimationCtrl(HWND hwndDlg, int nIDCtl) 
{ 
    HWND hwndAnim = NULL; 
    RECT rc; 
    POINT pt; 
	
    // Create the animation control. 
    hwndAnim = Animate_Create(hwndDlg, IDC_ANIMATE, ACS_TRANSPARENT | WS_CHILD, ghInst); 
	
    // Get the screen coordinates of the specified control button. 
    GetWindowRect(GetDlgItem(hwndDlg, nIDCtl), &rc); 
	
    // Convert the coordinates of the lower-left corner to 
    // client coordinates. 
    pt.x = rc.left; 
    pt.y = rc.top;
    ScreenToClient(hwndDlg, &pt); 

	// Position the animation control below the Stop button. 
	SetWindowPos(hwndAnim, 0, pt.x+10, pt.y,  
		149, 25, 
		SWP_NOZORDER | SWP_DRAWFRAME); 


    // Open the AVI clip, and show the animation control. 
    Animate_Open(hwndAnim, MAKEINTRESOURCE(IDR_AVI)); 
    ShowWindow(hwndAnim, SW_SHOW); 
	
    return hwndAnim; 
}

In addition to the window style in the creation, I also have it set for the resource.

It seems like I've covered everything, however, the AVI clip plays showing the white background on my gray dialog.

Anyone have any suggestions?

I think the problem is just in your AVI file. Did you set the transparency color in your AVI editor? I have only used the Animation Control once and all I had to do was import my AVI resource and call the Open method on the Animation control.

Also, my background color is RGB(255, 0, 255). I found that most AVI files I found on the Internet use this color as the background.

Tom,

I was able to get the transparency to work, however it only seems to work on video cards with 32-bit color depth. When I go down to 16-bit color depth, the magenta background that I have shows up. I am handling the WM_CTLCOLORSTATIC message in my message procedure to set the background color of the image to the dialog color as shown below.

case WM_CTLCOLORSTATIC:
    hdc = (HDC)wParam;
    // Get the dialog color
    dwColor = GetSysColor(COLOR_BTNFACE);
    // set the animation control to the dialog color
    SetBkColor(hdc, dwColor);		
    return TRUE;

Do you have any suggestions on how to get this to work with all video card bit depths?

Re: Build time switch for VC

14-Oct-02 4:08

Are you testing in XP? I've had a similar problem some months ago, everything worked just fine in every OS except XP. Finally, modifying the style right before opening the file seems to fix the problem:

DWORD dwStyle = GetWindowLong(hwndAdmin,GWL_STYLE);
dwStyle = dwStyle | dwAdd;
SetWindowLong(hwndAdmin,GWL_STYLE,ACS_TRANSPARENT);
Animate_Open(hwndAnim, MAKEINTRESOURCE(IDR_AVI));

I am sure there was a switch for Visual Studio 6.0 that displayed build times. Dammned if I can remember it though.

how can I suppress sending ICMP Messages ?

Koep14-Oct-02 1:39

14-Oct-02 1:39

Hi,

i have a own protocol stack implementation in Windows2000.
Wenn i send an udp Frame with a port xxxx ( to the Win2000 PC ), the WinSock Part of the OS sends an ICMP Message at the sender with
Type 3 : Destination unreachable
Code 2 : Port unreachable.
It doesn't matter to my program, because i can get the frame and make
my own processing. But how can i prevent these messages.
I think i could bind a (the)udp port to a socket and listen.
But these isn't quite good.
Can anybody help me ?

Sounds like you're breaking inside the memory allocation code; this is usually because you've trashed some memory elsewhere (tried to free memory twice, overwritten beyond the allocated area, written to memory after freeing it).

If you have a DEBUG build, there's usually a diagnostic of some sort generated in the output window when you run under the debugger.

STL Iterator question

Hi guys,

If I use the STL find algorithm, it returns an iterator. Is there any way for me to determine from the iterator, at what index the item was found?

Thanks

Assumming the iterator belongs to an indexed contaner c (like std::vector), then std::distance(c.begin(),it) should yield the index.
