I have a rectangular bitmap I want to transform into an arbitrary four-sided convex polygon. Is there any simple way of doing this knowing the vertices of the polygon? DirectX or OpenGL are not options.
The entire bitmap should be fitted within the polygon with the original corners at the polygon vertices.
Hopefully someone knows a way which doesn't require me to do all the skew/rotation/translation calculations myself 
Thanks in advance

It is a quadrilateral, isn't it?

Oh, noone here, I suppose, would deny you such a amusing task...

I had to look it up, but yes, it's one of them quadriwhatevers.

i know it's bad form to plug your own products, but this will do it[^]. though it's not free (not really expensive, either).
the DLL download package contains an app called ISDemo.exe, which does quad->quad warps.

As retriving the font name I need to retrieve glyf information from the ttf file. look at the code below this is not full code just a piece of code
void TTFReader::ReadGlyf()
{
setPosition(m_glyfOffset);//get glyf offset from the ttf file
for(int c=0 ;c < m_glyphs.size();c++)
{
int gl = m_glyphs[c];
//unsigned short k = readWORD();
unsigned short numberOfContours = readWORD();
unsigned short minx1 = readWORD();
unsigned short miny1 = readWORD();
unsigned short maxx1 = readWORD();
unsigned short maxy1 = readWORD();
setPosition(m_glyfOffset+m_ttf_pos);
gl = m_glyphs[c];
}
}
my code is not working correctly mean not giving the exact value for eg the number of contours for one glyph.

Dear All,
Can anybody tell me how to know a Hard Disk Drive(Including External USB Hard Disk) has S.M.A.R.T support or not?
Thanks

Have you looked at the WMI Win32_DiskDrive class?

Yes.It gives informations on Hard Disk Drives.But it doesn't show whether a Hard Disk Drive has S.M.A.R.T support or not.
Thanks

So what is the Capabilities field (with a value of 10) for?

Have you tried stepping into the function where the exception occurs?

Well, it is high time that you set up breakpoints and start debugging.

I have a problem when I set the text of a static text control. I do it with this code:
TCHAR buffer[sizeOfBuffer];
..............................
m_ProgressText.SetWindowText(buffer);
But the static control displays the text up to a point and many squares after that. The text might have newlines, but I don't know if that's the problem.

can you show your code for initializing the contents of buffer variable
You need to google first, if you have "It's urgent please" mentioned in your question.

I get it from a file (a pipe actually) with ReadFile. It comes as ASKII text, which I then convert to Unicode and pass to SetWindowText.

I just checked and it turned out ReadFile doesn't terminate the string, so the problem is solved

I guessed the problem would be with populating the buffer ...

Well, you have errors in your ado_mdiview.h. What else?

Hi,
I have two applications running in parallel.I want to know the events generated in one application (because of
user's action on dialog controls)in the other application.
Those two applications are not communicating with each other directly.But the second application has the info of
dialog control ID's of the first application.
Is it possible to know the events generated in other application.?
Please tell me how can I do it.
Regards,
Sunil Kumar

Well, yes - Spy++ can do it.
I suspect you need to create a global Windows hook that gets injected into the first application which can send information to the second one.
Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p
