You have to correctly identify the code page of the original string. You are not. If you have a multi-byte Japanese string using Shift-JIS, you need to use that, not UTF-8. The point is that UTF-8 is a very specific encoding, not just multi-byte in general.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

You are right. We need to identify the appropriate code page and then accordingly use UTF8/ACP.
I think for eastern languages it is UTF8 and for European languages it is ACP.
Thanks a lot for your help.

I need to know if its possible to load a file from hard disk and then
set the quality of jpeg and save the file as a jpeg file
i am using Cximage class and the folowing code
CxImage image;
image.Load("D:\\mypic1.bmp", CXIMAGE_FORMAT_BMP)
if(image.IsValid())
{
image.SetJpegQuality(70);
image.Save("C:\\mypic.jpg", CXIMAGE_FORMAT_JPG);
}
But the code does not seem to work.
Help would be appreciated
Thanks

just a personal advice, why don't you use I Imagemagik library instead of CxImage?

I have a suggestion for you instead this code
you can use of CImage class(it has good methods for work on images) and its simple and like this:
CImage image;
image.Load(_T("D:\\mypic1.bmp");
....
....
image.Save(_T("C:\\mypic.jpg"));
or
image.Save(_T("C:\\mypic.bmp",Gdiplus::ImageFormatBMP);

I am trying to use Cximage class in my own visual C++ project.
I am using Visual Studio 2008 Professional Edition
All i want is to read a BMP file from hard disk and save it as a Jpeg file
But when i use the object of the CXimage class upon compiling i get a large
number of error of unresolved external symbols e.g
cximage.lib(ximaraw.obj) : error LNK2019: unresolved external symbol
This repeats for all the tiff,jpeg.... objs
Any One can help me out i am having nightmares using cximage class.
Thanks

Sounds to me like you haven't included all the associated libraries that CxImage uses to read/write the different image formats - they all look to be included in the source.
If that's all you want to do, though, and you're using VS2003 or later, I'd use an ATL/MFC CImage[^].

I have only imported to cximage.lib file.
As rest of the library files to include i cant find.
I am downloading the linked library files from http://www.xdp.it/cximage/
But after unzipping the files i cant seem to find the ".lib" file of each of the linked libraries
Do i need to compile the downloaded projects if so with what settings
I am using Visual Studio 2008
Thanks

To create a DLL project, go to the "File" menu, select "New Project" and then "Class Library" - that will generate a DLL instead of an exe.
I'm not sure I really understand what you want the DLL to do but it sounds like a file open dialog, which you don't really need to have as a separate DLL unless it's going to do some other things with the file.
There are three kinds of people in the world - those who can count and those who can't...

To expand on molesworth's answer, Win32 provides GetOpenFileName[^] (let the user select a file/files) and SHBrowseForFolder[^] (let the user select a folder).
Both are usable from VB6, if htat's what you need:
SHBrowseForFolder[^]
GetOpenFileName[^] - this example's VB5(!), but VB6 and VB5 are similar enough...

I think you dont need to make a dll for it you can use of these apis on VB(Stuart Dootson' answer).

Any specific reason for creating dll, when you achive same by simply writing a function in your application?

Can someone direct me to an article if this is possible.
I have 3 interloops in a process that takes about an hour or so to complete, based on the data it seems to be right.
However I have that process in it's own worker thread. I was wondering if that can be further multithreaded?

As you've mentioned a 'for' loop, I think OpenMP[^] is probably the simplest first thing to investigate, as it's aimed at that sort of thing[^].
Here's a CP article[^]...

Yes and No!, answer is based on software design, your company software architect can help in this case. It very difficult to answer this question from remote.
