Has Windows Vista got graphics routines to read from JPG images to internal image mode, and to output from internal image mode into JPG mode? If so, how does Visual C++ call those routines?
|

GDI+[^] wll handle JPEGs plus several other types.
It's included on XP+ operating systems and available as a redistributable for versions
back to Windows 98.
If you use the CImage class[^], which uses GDI+ to load and save images,
you can load and save images with just a couple lines of code.
You can also look at the CImage class source code to see how it uses GDI+.

So far my atempts at telling Visual C++ programs to display text have displayed mostly Chinese characters, mixed with occasional Japanese katakana and Arabic letters.
I have realised that I may have run foul of a confusion between the ordinary 8-bit characters that I have known since the beginnings of desktop computers, and the Windows 16-bit characters that include national character sets (including Chinese characters). Please, starting with
char*s = "The quick brown fox jumps over the lazy dog's back.";
(which is 51 characters (not counting the terminating /000 character)), how can I tell the program to convert that into the Roman-alphabet 16-character form so the program will display that in the Roman alphabet?

I don't know, ever heard of UNICODE ?
on another tangent, there is a macro, I think, called A2W that converts LPSTR to LPWSTR, you can start by looking at those and start your education from there.

I need a small function or code to do interpolation. Knowing Y(Xi) to fine y(x) for a give x.
If you have a code please share with me.
Thanks

y = (x-x1)*(y2-y1)/(x2-x1)+y1;

Thanks for your message.
I know the math behind a interpolation. Now I am looking a ready code or function.

He's given you the code. Just wrap that into a function, with the relevant parameters, returning the relevant result.
Barring him coming round to your office desk, there's not much more he can do for you.

Interpolation is heavy duty if you have complex functions. You better implement an acurate function.

Thanks and greeting from US.
I am looking for some code and save me to write again.

If you need an interpolation function, you need to specify what exactly you need to interpolate.
Ie. Linear? Quadratic? Cubic? Higher Polynomials?

Thanks.
Spline will be good.

I often copy a full directory of a proiject to another director and change the programs
to another application, but I still have to use the same project name. When I got the new compiled
excutable file. its name is still the same as the old one.
This is a MFC program project. I do want to change the project name and get new name for the new application. I do not knw how to change the project and program excutable names.
Thanks

Edit the project setting: Linker/General/Output File
It may be a good idea to go through all the settings of the copied project and
make sure there's no settings that still relate to the old project

Hello,
I have a 5.1 audio card and i want play a different song on each speaker.
Actually, I Create a directsound buffer, load my wav and i play it but It is played by all speakers.
I have no idea how to play my directsound buffer in one sepaker.
Thanks......

The 5+1 channels of Dolby 5.1 are a different sort of thing altogether to the Channels in direct sound. To control the Dolby channels directly you would have to use a low level API targetted at your sound card or write your own card driver. Depending on how your sound hardware is implemented it may not even be possible then.
Nothing is exactly what it seems but everything with seems can be unpicked.
