Re: File I/0 Functions

Hello!
I created a file in "c:\\x.txt" and after with a form I created 2 buttons ( write and read) to write and read from that file and 1 textbox!
I want to know how can I write in textbox many times and when I'll read from the file (pressing Read button), to be capable to find all my TEXT that I saved before!
I tried with FileSeek and FileEOF, but still not working!
Thank you!

Have a nice day!

Hi.

First of all you need to make sure you have Read and Write access to the file. In this case I am creating the file from scratch every time.

lFileMode=aFileModeCreateNew or aFileModeRead or aFileModeWrite
textFile=FileOpen(GetDir(aGetDirCurrent)+"\\FileRead_"+str(Tick())+".txt",lFileMode)

Second, when reading from the file you need to select the beginning location of the file if you want to read all the files contents.

FileSeek(textFile,0,aFileOriginBegin)
lBytes=FileRead(textFile,sText)
tbTextFileView.Text=sText

I attached an example.

Regards,
Orr
