Let's say - for a setup-like application; you could pack an unpacker program and the compressed data in an unique file, for easier download. That's easy enough - just "adding" the compressed data at the end of the unpacker exe file.
But .. under Windows NT, you can open an exe file at runtime, using the standard CFile class, read it, and save in a temporary location part of the file; this method doesn't work under Win9x though.
Anybody knows a better way that works under every MS OSes ?
Thanks!

I am implementing a listview for a touch screen application. I have placed a CSpinButtonCtrl next to the listview to make it easy to scroll, without having to fiddle with the scroll bar. The question is, how do you PERMANENTLY remove the vertical scroll bars from the listview, without settings the no-scroll option in the dialog template editor.

Does anybody know, how to play AVI-Files during an application ?
I would like to it with DirectShow, but i would have to Download the whole DirectX SDK (128Mb !!!).
Does anybody know, where i could download only the DirectShow SDK, or any other solution, how to play AVI-Files ?
|
|
|
|
|
Ahh you're making the same mistake I did!! 
DirectShow is NOT part of the DirectX toolkit. MS for some unknown reason decided to move it to the DirectX Media SDK which is spearate! I only learn't this after a 128M download! I does actually say this on the web site, but it is not very clear at all. (Us lot over here in England put it download to our lack of ability to read American!)
Anyway why use DirectX? Try a CAnimateCtrl....

Hi,
in my app. i have this code:
The first part loads 2 bitmaps, 1 normal and one inverted one (used as a mask by windows):
HANDLE m_hImage;
HANDLE m_hNegImage;
m_hImage = LoadImage(AfxGetInstanceHandle(), MAKEINTRESOURCE(IDB_NORMAL), IMAGE_BITMAP, 0, 0, 0 );
m_hNegImage = LoadImage(AfxGetInstanceHandle(), MAKEINTRESOURCE(IDB__INV), IMAGE_BITMAP, 0, 0, 0 );
Next i create a cursor with the info given:
ICONINFO info;
HCURSOR m_hCursor;
info.fIcon = FALSE; // means it's a cursor
info.xHotspot = 11;
info.yHotspot = 0;
info.hbmColor = (HBITMAP) m_hImage;
info.hbmMask = (HBITMAP) m_hNegImage;
m_hCursor = CreateIconIndirect(&info);
Next i override my OnSetCursor code to do my own implementation:
SetCursor(hCursor)
This code works absolutely fine under WinNT 4.0 but not under Win98. I imagine Win98 can't handle the size (rather big) of my own cursors. Anyway, all the functions return fine and work ok except it displays the standard cursor and not my own creation.
Does anybody have a clue on how i can still use my own images (and thus cursors) in my application under Win98?
Thanks

How I can get the list of availablis data members of the A class and their type, if there is an object or pointer on the object of the A class? (with C++ means only, w/o programming with assembler)
It is said, it is impossible.
Whether so it?
Thanks.

Hi,
I'm using a WebBrowser control inside a CView class. I've
used the ClassWizard to encapsulate the control's functionality,
but although I've used SetWidth() and SetHeight() to set
the right values, I can't get rid of the vertical scrollbar
on the right. SetResizeable(FALSE) returns a funny message,
and none of the CWnd scrollbar functions seem to have any
effect.
Any help will be greatly appreciated.

This can be done with the IDocHostUIHandler interface that you must implement in your container (CView derived class). Look at GetHostInfo and returning with docHostUIFlagSCROLL_NO flag set.
In ATL support for this interface is built in. You can look at the implementation of CAxHostWindow for an example implementation. A description of some of this can be found in ATL Internals.

void CDaTestView::OnInitialUpdate()
{
CView::OnInitialUpdate();
m_WebBrowserCtrl.SetLeft(0);
m_WebBrowserCtrl.SetTop(0);
m_WebBrowserCtrl.SetWidth(156);
m_WebBrowserCtrl.SetHeight(92);
if(m_WebBrowserCtrl.EnableScrollBar(SB_BOTH, ESB_DISABLE_BOTH) == TRUE)
TRACE("Cannot disable scrollbars!");
m_WebBrowserCtrl.ShowScrollBar(SB_BOTH, FALSE);
// Initialize the first URL.
COleVariant noArg;
m_WebBrowserCtrl.Navigate("file://D:/PROJECTS/MosaicLCD/default.html",&noArg,&noArg,&noArg,&noArg);
LPDISPATCH pDisp = NULL;
IDocHostUIHandler *pHostUIHandler = NULL;
pDisp = m_WebBrowserCtrl.GetDocument();
ASSERT(pDisp);
pDisp->QueryInterface(IID_IDocHostUIHandler, (LPVOID*)&pHostUIHandler);
ASSERT(pHostUIHandler);
if(pHostUIHandler)
{
DOCHOSTUIINFO *pInfo = NULL;
pHostUIHandler->GetHostInfo(pInfo);
if(pInfo)
{
if(((pInfo->dwFlags) & DOCHOSTUIFLAG_SCROLL_NO) == (pInfo->dwFlags))
TRACE("Scrolling enabled");
else
TRACE("Scrolling disabled");
}
}
if(pHostUIHandler)
pHostUIHandler->Release(); // release document's command target
if(pDisp)
pDisp->Release(); // release document's dispatch interface
}
I'm creating the m_WebBrowserCtrl in CDaTestView::OnCreate()
but I get an assertion in the line
pDisp = m_WebBrowserCtrl.GetDocument();
ASSERT(pDisp);
pDisp is NULL! Any idea why? Is there something else wrong
with this code?
Thanks in advance

You must wait for the DocumentComplete event from the Web browser control before you can get the document. Also you must implement the IDocHostUIHandler interface. The Web browser control will call your GetHostInfo method. You might be able to find some example code for this interface using MFC.

Hi,
Does anyone know how to create child windows/controls in Visual C++ from an Add-In? I've seen
an add-in that makes Visual C++ look like Visual Basic by adding similar dialog bars, etc.. How can I
do that? Maybe there's COM interface for that?
|
|
|
|
|
Can you give a url to that add-in?

Hi,
I have a problem with variable arguments.
I'll try to explain it:
Supposed there is a function, which is prototyped as follows:
int OriginalFunc(int n, ...);
Now I will add some code around this (bought) function like this:
HRESULT EnhancedFunc(sometype somevar, ...)
{
do some enhanced things with somevar;
do some more enhanced things;
// now I call the original function
if(OriginalFunc(?????????))
do some errorhandling;
do some *really* enhanced things
return S_OK;
}
So the question is how to pass a variable argument list through to another function which uses va too?
bye,
rootair

You can't directly. Instead you must call a version with the va_list arguments.
Its like the use of sprintf and vsprintf. One for this, one for that.
|
|
|
|
|
Thanks for the hint, but I already knew that. Unfortunately there isn't a va_list version of that function...
