If that's what your screen looks like, you should skip the pr0n when trying to write code. Posting screenshots to a site that displays ads showing nipples and viagra tablets is probably not the wisest idea.. :laugh:

That said, I see 4 references to dir in your code, yet I don't see it declared anywhere - which, oddly enough, is just the same error that Intellisense reports.

How is dir declared? Or more to the point, are you sure that you have declared it?

dir declared like this:
DIR *dir;

*once

Sorry about the site and the pictures I did not know it was like that the first time I bring up this site

You could just post the error message here.

No problem, no harm done. Just something to be mindful of in the future - many others will have a problem with links of this nature. :)

You never declare the symbol dir. How can this message be unclear? Declare the variable or a type member. If you already have the declaration of the variable or member under the same name and still have this error, it means it is done in the scope not visible in the content you are trying to use this object. C++ scope and visibility rules are extremely simple, you can learn them in no time. Please do, otherwise you hardly can go far.

And please, this question requires pure textual information: some code sample + error information. Was it so difficult to provide this information in your question in the form of properly formatted text? After all, you have a clipboard. A screenshot is extremely inconvenient.

i have Declare the variable . And still have the problem

The problem could be because I added maybe not good for the dirent.h ?
the code:

DIR *dir=NULL;
CString str=getCurrentPath();

//cstring to char*
CT2A ascii(str);

const char* path2=ascii.m_psz;
dir=opendir(path2);

struct dirent *ent;
if (dir != NULL)
{
/* print all the files and directories within directory */
while ((ent = readdir (dir)) != NULL)
{
string name=ent->d_name;
CString name2(name.c_str());
lbTextureFiles->AddString(name2);
}
closedir (dir);
}

Yes, in this fragment you did, but it won't show this error. But don't declare it there. It should be in one like:
DIR * dir = opendir(path2);

I did what you said and I still have trouble trying to answer the second thanks anyway for the help

Sorry, I failed to understand you last comment. What "second"? Does this fragment of code compile now?

I just want to get the file paths in some directory

Sergey Alexandrovich Kryukov 6-Aug-14 14:45pm

Get from what data? What prevents you from getting it?

Please note opendir is a Linux function (see opendir man page[^]). Look at this Stack Overflow question for suggestions: "Microsoft Visual Studio: opendir() and readdir(), how?"[^].
