Hi Everyone,

I'm using WinIOCallBack in EBML library to read file. My code here :

MKVFile::MKVFile(const std::string &FilePath)
{
    m_FilePath=FilePath;
    WinIOCallback *pIOCB=new WinIOCallback(m_FilePath.c_str(),MODE_READ,0);
    //Check if file is exists
    if(!pIOCB->IsOk())
    {
        printf("File doesn't exists");
        
//delete a pointer
        delete pIOCB;
        mOk=false;
        return;
    }
    else
    {
        printf("file is okies");
    }

When I debug at line 3 then receive an error :

pIOCB = 0x003a78e8 {mOk=false mLastErrorStr="The system cannot find the file specified."mCurrentPosition=14829735431805717965 ...}.

I'm trying debug but I don't understand the error derived. Can Everyone explain and fix bug for me.
Thanks

What is the value in m_FilePath.c_str() ?

Quote: "The system cannot find the file specified." - pretty big clue don't you think.. It means whatever your file path is, the file it points to doesn't exist. Basically, your file path is wrong!

The file is not available in that path. Put a breakpoint on the 2nd line and check what is the value of FilePath.

Solution 1

Run it through the debugger again.
Put a breakpoint on the line:

m_FilePath=FilePath;

When you get to the breakpoint, look at FilePath, and see what it contains. Then look at exactly that path, and see if the file exists. Bet it doesn't!
