File Stream I/O

jsheley

I have a bit of code that makes no sense. What appears to happen is that the "OpenFileDialog" varible neutralises the File I/O. Specifially, the code below works as expected. A file named "Master_Sel.txt" is opened, and "TEST_DATA" is written into it. The file is closed. OpenFileDialog LIB_OPEN = new OpenFileDialog( );// //LIB_OPEN.ShowDialog();//<= Problem Child (%$#$@!!) LIB_OPEN.Dispose(); BinaryWriter LIB_File_Writer = new BinaryWriter(File.Open("Master_Sel.txt", FileMode.OpenOrCreate)); LIB_File_Writer.Equals(LIB_File_Writer.BaseStream); LIB_File_Writer.Write("TEST_DATA"); LIB_File_Writer.Flush(); LIB_File_Writer.Close(); When the "//LIB_OPEN.ShowDialog();" line is un-commented, the Open file dialog appears as expected, but there is no file I/O. This also happens with "Filestream" and Stream writer functions. Can some explain to me how to avoid this problem?

Perhaps the LIB_OPEN dialog changed your working directory(current directory), and "Master_Sel.txt" is created in another directory, not the directory you expected. BINGO!! This is exactly what is happening! Are you Bill Gates? Thank you who ever you are! Relief!!! Salvation! The Angels sing! Joy to the world! The nefarious bug is dead!
