Set position in Stream
Please support our C++ advertiser: Programming Forums - DaniWeb Sister Site
Thread Solved |
When reading a txt file I am using .seekg to set the startpoint in the file to read from.
linepos has a value: 1002106
First I wonder what this value stands for excatly. As I have understand this is how many characters forward in the file that will be the absolute position from where the reading will start.
Now I am using StreamReader wich also has the ->Seek wich needs 2 arguments.
However when I am trying to put a startposition like this it will not compile.
What I wonder is how I can use the Pos Value to put this to ->Seek( , );

//File1.seekg Seek to right point in file to start reading from File1.seekg( linepos ); int Pos = linepos; //Pos gives a value of 1002106 StreamReader^ sr = gcnew StreamReader(FileToRead); sr->BaseStream->Seek(0, Pos15); // ::SeekOrigin might need to be used in any way sr->BaseStream->Seek(0, System::IO::SeekOrigin::Begin = Pos15);
