I don't agree. There are many programs that need to deal with input in different encodings and it makes a perfect sense to convert all this text to Unicode before processing it.

Yes, I fully agree with you. But if you look closely at his question (and some others), and moreover the post from CPallini, then you can see that there is something wrong with his design. When you have a quite 'basic' application (MFC in this case) and only interact with the user through the UI, then in general (but again, there might be exceptions) you don't have to use a lot of string conversions. That's what I wanted to say (well, I agree, it was not very clear  ). Anyway, reading the link I provided to him is always usefull.

Since the parameter 3 of the WideCharToMultiByte must be a wide char string and your CString object doesn't provide a suitable cast operator, I guess your CString instance is already ANSI (i.e. you're not doing a UNICODE build) and doesn't need to be converted.

For unicode to ansi conversion and vice verse, better use macros such as A2W and W2A. They are more easier to use. Check here[^] for code snippet.

The macros are outdated. There are now templates in the ATL (String constrcutors) to deal with that tasks.

They are outdated?  Well, Thanks for the info.

Since you do not have Unicode defined, word is not going to be a wide, thus no conversion is required.

Hello evrybody.
I would like to know how can I retriev the program path once it is installed.
When my executable is launched I would like to acces program ressources like images, xml files.
These are all situatted in relative paths : ie in directories insidethe same dir as the executable it self.
The problem is that many utility functions that loads the ressources only accepts full paths, ie they would not accept something like the following :
./BMPs/tunisia_flag.bmp
So How can I translate that dot (.) to them, how to retrieve the application path ?
Is it possible at least to store the user chosen installation path of the application into registry at installation time, using the SetupProject type so to be retrieved by the application at run time ?
Thank you in advance.

You can use GetCurrentDirectory [^] function to retrieve the directory when the application is launched and store it for later use.

That won't work if the program is launched with a non-default (i.e. different from EXE's directory) working directory.

Code is here
DWORD dwDrives=GetLogicalDrives();
if(0==dwDrives)
{
return FALSE;
}
DWORD dwCount=0;
char chDriveLabel='A';
char szRootpath[5]={0,0,0,0,0};
while(dwDrives !=0)
{
if ((dwDrives & 1) != 0)
{
sprintf(szRootpath,"%c:\\",chDriveLabel);
//removable drive
if(DRIVE_REMOVABLE==GetDriveType(szRootpath))
{
WIN32_FIND_DATA FindFileData;
HANDLE hFind;
//Removable dirve lable
// std::cout <<"Files in " << szRootpath << std::endl;
m_ListCountries.AddString(szRootpath);
//* represent search all files and directories
szRootpath[3]='*';
hFind=FindFirstFile(szRootpath,&FindFileData);
if (INVALID_HANDLE_VALUE == hFind)
{
// return FALSE;
}
// List all the files in the directory .
do
{
//ignore the sub directories
if (!(FindFileData.dwFileAttributes &
FILE_ATTRIBUTE_DIRECTORY))
{
m_ListCountries.AddString(FindFileData.cFileName);
}
}while (FindNextFile(hFind, &FindFileData) != 0);
FindClose(hFind);
}
}
dwDrives = dwDrives >> 1;//next drive
chDriveLabel++;
}
return true;

Sir,
since yesterday, don't you see that your [code][/code] tag does work ?
use HTML (through the buttons below the typing area)...

Why don't you handle the FindFirstFile failure?

Which is all you should be getting by using the cFileName member. The WIN32_FIND_DATA structure contains no path information as you already have access to that.

When you used the debugger to step through your code (which I'm sure you did  ), what did you find?
