How come line 1 will output garbage to the screen, but line 2 will output a 
good number to a file?

How can I make line 1 out put a good number to the screen







String* dayStr = System::DateTime::Now.ToString("dd");

Int32 dayInt = System::Int32::Parse(dayStr);

Console::WriteLine("the day is {0}", __box(dayInt) );     // Line 1



                                      .

                                       .

                                       .





String* path = new String("_1D.txt");  // will read the time from a file

FileStream * fs = new FileStream(path, FileMode::Open);

BinaryReade* br = new BinaryReader(fs);

Int32 day    = br->ReadInt32();



fs = new FileStream(S"_1k.txt", FileMode::Create); //will write the time to 
another file

BinaryWriter* bw = new BinaryWriter(fs);

Br->Write( day); 
//Line  2

What kind of "garbage"? The wrong number? Random characters? An exception?

Why do you create a string and parse it? Why not simply:

Int32 dayInt = System::DateTime::Now::Day;

You forgot to close the stream here.

Hi Gran,



I really appreciate your help.  I learn a new way to deal with DateTime 
which is (Int32 CurHour = System::DateTime::Now.Hour), but now I have a 
problem.



Format1(your format):  Int32 dayInt = System::DateTime::Now.Day;




Format 2 (The one I use before):  Int32 dayInt = System::Int32::Parse(dd);

                                                                        Int32 
CurHour = System::DateTime::Now.Hour;



Now, after I use format 2 instead of format 1, the things went to the 
opposite, which is I get garbage (random character) when I write to files 
and get good numbers when writing to the screen.



To answer your questions:



Why do you create a string and parse it?



The answer is, that was the only way for me to get good number into the 
file.



What kind of "garbage"? The wrong number? Random characters? An exception?



The answer is Before I was getting wrong numbers.
