BTW, forgot to mention, below are the parameters to the API:

char Description[132] = {0};
char Description[132] = {0};
TCHAR szName[132] = {0};
.
.
.
.

int nLen = MultiByteToWideChar(CP_UTF8, 0, Description, -1, szName, SIZEOF_ARRAY(szName));
// nLen is around 30, the no. of chars copied

This API works fine.
The problem is your machine language may be set to English.

So first set the machine language to French.

Go to Control Panel->Regional and Language options
In both "Regional Options" and "Advanced" tabs selct Frech language.
It will ask you to reboot the machine.
Reboot it and check now.
It will work fine.

"é" is an ANSI character (code page 1252), but doesn't have a single character representation in UTF-8.

Please remove your answer because it is 100% wrong.

Thanks Sujeet.
But as you said my system language is already set to French. Not sure why the problem still exists.
Could you think of anything else ?

Thanks

The accented e is a second, third, or fourth byte of a multi-byte sequence for a UTF-8 encoding and thus is invalid as a stand-alone character.

You should likely use 1252 as the code page.

Hello

Thanks for your time.

It is not only this character that is failing, but it definitely fails on Chinese/Japanese as well.
Could you think of anything else ? Also i use a lenevo c200 system, one which i have encountered numerous string errors in my dev life Sniff | :^)

.

Thanks

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.

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.

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);

CxImage Class Error

Muhammad Hassan Haider24-May-09 2:27

24-May-09 2:27

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

Hassan

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[^].

Re: insersion in 2D Array

24-May-09 10:41

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).
