I am trying to search all sub directories for a symbol and replace it with another. The code below works for a specified path but it will not search sub directories.
I have a 133 Mb file which contains almost a million records. Currently, a user loads this file into KEdit (a great editor for working with large files) and changes occurrences of a dollar sign $ to blank and takes negative numbers represented as such with parentheses and changes that to a negative sign. That is, (5000.23) would become -5000.23. So the leading ( becomes a - and the trailing ) becomes a blank. I believe the only occurrences of ( and ) are around the numbers I want to change, so I don't have to worry about changing something that should have been left alone. Using VB.NET in Visual Studio 2008, is there a "painless" way to do this other than reading the file one record at a time and searching/replacing and writing the record out? While not really painful, I am worried about how long that will take (to run, not to code ). Is that a valid concern?
My long range goal is to automate many of the routine file preparation tasks my users do. We get an input file from 15 clients. The file can be in any format the client has chosen to give us, and it is our burden to reformat any errant fields into an acceptable format for insertion into our database.

I am writing a program and I have the Read Function all written out. I need to have the write function. I think is I copied and pasted from the Read function I wrote.
I was able to Mass edit This: Reader.Position = (&H) NumericUpDown281.Value = Reader.ReadInt16() Reader.Position = (&H) NumericUpDown280.Value = Reader.ReadInt16() Reader.Position = (&H) [Code] .....
And there is at least 370 NumericUpDown's. Is there any way to search/find/replace all in one instead of typing: Find what: NumericUpDown320.Value = writer.WriteInt16() Replace with: writer.WriteInt16(NumericUpDown320.Value) Each individually?
The write function will only write properly this way: writer.Position = (&H) writer.WriteInt16(NumericUpDown66.Value)
And not this way: writer.Position = (&H) NumericUpDown319.Value = writer.WriteInt16()

I'm having a bit of a problem getting my application to close properly. Basically I have one main form from which all other forms open. If a user tries to close that main form, I want to bring up a MessageBox asking if they want to exit the application.However, when I try to do that it asks the question twice. It seems that the Application.Exit() is triggering the FormClosing event again for some reason, but I don't know of another way to exit the application. BTW, the main form isn't the startup form so I can't use the option to close when the startup form closes.
