This is answered in this forum before, you can try search the forum!
But, to send a bitmap you just read the bitmap file in binary mode and then simply send(bitmap_data,...)! Smile | :)

or something! Smile | :)

Updating Resource in Windows NT

Hi!

I'm using the Win NT UpdateResource API to change the main icon of a program. My code works well if I extract an icon from a module (EXE/DLL) and I replace the destination icon by this one.

Here my code:

<br />
HANDLE	hUpdate;<br />
char*	lpResLock;<br />
HINSTANCE hExe;<br />
HRSRC hRess;<br />
<br />
hExe=LoadLibrary ("c:\\winnt\\explorer.exe");<br />
hRess=FindResource (hExe, MAKEINTRESOURCE (10), RT_ICON);<br />
lpResLock=(char*) LockResource (LoadResource (hExe, hRess));<br />
<br />
hUpdate=BeginUpdateResource ("c:\\winnt\\calc.exe", FALSE);<br />
UpdateResource (hUpdate, RT_ICON, MAKEINTRESOURCE (1), 1036, lpResLock,SizeofResource(hExe, hRess));<br />
EndUpdateResource (hUpdate, FALSE);<br />
FreeLibrary (hExe);<br />

I would now like to do the same thing but instead of extracting an icon from an module, I would like to get the icon from an ICO file.

How can I use UpdateResource API with an ICO file? Confused | :confused:

Thks in advance!

Something like this:

Tempfile access from other process

Hi,

If I create a tempfile with _open (_sopen) and _O_TEMPORARY-flag I can write to this file but I hav'nt access from an other application. Here the complete Code:

int fh = _sopen ("tempfile.ext", _O_BINARY | _O_RDWR | _O_CREAT | _O_TEMPORARY, _SH_DENYNO, _S_IREAD | _S_IWRITE);
int written = _write (fh, (void *) buffer, sizeof (buffer));
StartApplication ("tempfile.exe");
_close (fh);

Is anybody out there with an solution? I hoped, if I close my 2nd Application (he should open the tempfile for read), the system delete my tempfile automaticly.

Chris,
It looks like he migh have done something like this, maybe??:

typedef vector<CString> vect;

error C2440: '=' : cannot convert from 'const class CString *' to 'class CString *'

Could you be having a problem with a copy constructor or do you not have to deal with those when working with the CString's?

Take a look at this:

You can copy, delete, rename, xcopy, deltree, move files and folders with ease. I believe that's exactly what you are looking for.

CHtmlEditCtrl Control Creation Failed

Hi!

I'm looking for creating a program in which I would like to add a dialog which contains a Html Edit Control like the one we can get by using the Document/View architecture with the CHtmlEditDoc class as the Document Class.

Here a portion of my code:

BOOL CHTMLCDlg::OnInitDialog()
{
CDialog::OnInitDialog();

CHtmlEditCtrl m_HtmlEdit;
m_HtmlEdit.Create ("",0, CRect (0,0,100,100), this, 1);
....

I get the following error:
error C2248: 'CHtmlEditCtrl::~CHtmlEditCtrl' : cannot access protected member declared in class 'CHtmlEditCtrl'

Does anyone could help me?

Thks in advance!

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"));

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.

Problems with animation control

Brigg Thorp14-Oct-02 1:55

14-Oct-02 1:55

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.
