One efficient way to do this (I'm sorry I shouldn't use the word "effcient" because it carries out endless debates ).
One way to do this is through a custom based COM filter using DirectShow (now completely integrated in DirectX 8.x). If you are planning to use this as a one time tool, you could avoid the code involved in plugging the filter into the GraphFilter of DirectShow and use the GraphEditor instead.
The filter needs to get a stream input of the sample video in order to create the file that you want (i.e. bitmap). For instance,
//
// Copy the input sample into the output sample
// Then transform the output sample 'in place'
//
HRESULT MyFilter::Transform(IMediaSample *pIn, IMediaSample *pOut)
{
HRESULT hr = Copy(pIn, pOut);
if (FAILED(hr)) {
return hr;
}
return Transform(pOut);
} // Transform
//
// Create a bitmap from source and let dest be identical
// in order to continue the process (playing).
//
HRESULT MyFilter::Copy(IMediaSample *pSource, IMediaSample *pDest) const
{
...
}
There is much more work involved in developing a DirectShow filter. I hope this help you out.

I installed .Net,and I found the component writed with VB was correct while debug step by step,then I make the dll.But it does not work correct.(In one method of this component ,I called one function of another dll just for unzip files.)
If this is caused by .net?

Hello everybody,
In a program i need to change the style of a ComboBox (Using Win32 SDK in ATL) from CBS_DROPDOWN to CBS_DROPDOWNLIST (either way). I tried using SetWindowLong() and ModifyStyle(), but failed in both the ways and failed to get what i want. If anybody knows plz help me. Even i tried with subclassing.
Thanx in advance.

|

I think you'll have to re-create the combo - you can't change these styles at runtime. Save the control ID and position, then call DestroyWindow and Create with appropriate styles.

I want to know why the results of debug version and release version are not identical when using VC++? (My program has no memory leak.)I set 4 level-warning in project settings,and I am sure that all the variables are initialized,but some results aren't the same slightly,for instance:"Waist=75.620499,Knee=36.650490 "in release version and "Waist=75.630901,Knee=37.181105" in debug version.I suspect if the problems consist in float type,thanks for any help.

I have an appwizard generated SDI app. The one and only change is that my CView is a CHtmlView. The code generates an exception in the 2nd iteration of CHtmlView::OnSize() - so the program crashes immediately. I have a clean windows 2000 SP2 installation, visual studio 6 SP6 and IE5.5.2. Thought it might be a problem with whatever dll contains CHtmlView so I have tried reinstalling IE, etc.
I'm going nuts. Anyone got any ideas?

Hi there, reader of this message! The problem is this piece of code. I'm using MFC and using the resource manager I've drawn a bitmap button in a dialog box and using class wiz I assigned it, the name m_button. I've put this piece of code in OnInitDialog:
CBitmap bitmap;
bitmap.LoadBitmap(IDB_TREE);
hBitMap = (HBITMAP)bitmap;
m_button.SetBitmap(hBitMap);//IDB_TREE is a 16 mil col btmap, but I tried with 256 and still doesn't work. The code compiles but there is no effect. The button is as dull as always, there is no picture upon it nor any text(shouldn't be any text). I'm sure there is a simple answer, so great computer genius, would u be so kind as pointing me to it? Many thanks and happy prog!
To live in truth!

First of all, operatorHBITMAP is defined for CBitmap, so you can pass a CBitmap where a HBITMAP is expected. I think from memory you need to set the bitmap button to be owner drawn though. I always use AutoLoad for bitmap buttons, you create the bitmaps as resources and name them with quotes like this "ImageOne" "ImageOneX" etc. Then the caption on the button needs to be "ImageOne", and you call autoload, and get up to four bitmaps loaded ( up, down, disabled, and I forget the fourth ).
Look up Autoload in the MSDN, you'll probably find it's a better option.

Your CBitmap object goes out of scope after OnInitDialog() returns, which destroys the bitmap object. Move the CBitmap object to a member variable.

Hi,
Make sure the style of the button is BS_BITMAP (but I'm sure you did).
Then try to use a member CBitmap variable, otherwise the bitmap is destroyed as soon as the viariable goes out of scope.
Hope this helps,

Does anybody know how to convert from float to LPSTR?
for Example:
float x = 1.56;
LPSTR text;
and now???????
|
|
|
|
|
char buffer[10];
float fp = 12345.123
sprintf(buffer, "%f", fp);
It should do the trick, take a look at sprintf() in MSDN...

Yes the _fcvt function.
<br />
char *_fcvt(double value, int nDigits, int* ndecposition, int* sign );<br />
Cheers!!!!

I prefer the _gcvt
the _fcvt return a static pointer, there for I think it will have problems with multi thread app.
BTW: for some of you that wished for CodeProject irc server
I create a channle on DalNet called "#CodeProject"

In C (or C++) :
float x = 1.56;
LPSTR text;
/* allocate memory for 'text' */
sprintf( text, "%f", x );
---------------------------------------
In C++ :
#include <sstream>
float x = 1.56;
ostringstream out;
out << f;
string s = out.str();
// s.c_str() can be written to 'text' now
---------------------------------------
Alternatively, you can look for fcvt() on your platform (Windows, I'm assuming).
