Binary File - Read A Byte[] Array To EOF

Mar 7, 2010

Some binary files have application variables at the end if you open it with a text editor you can see these variables. Now when I read these files into the processor memory the program does not work properly, however if I read a file without this it works fine. So how can I read a byte[] array to EOF so that when I pass that byte array into win32 api create-process it will create the process without corrupting the program?

Read Text File And Stop Then How To Continue At The Last Read Point

Dec 15, 2009

I'm using vb.net 1.1 to develop the program. I got text files that contain test result from a machine, like below.

T1 1.24535 2.56335 2.43253 1.24538 2.55619 4.35243
T2 1.42542 1.63728 3.57295 4.59275 1.57320 2.72057
T3 5.12857 2.45375 6.38593 2.58375 3.57259 3.57204

I need to check the test result with the data from database, to find out which test result is failed. If there is a fail test result, I will show an alert to the operator and stop the checking process. Until the operator close the alert, then the checking process will continue from the last read point.

May 26, 2008

how to do this for vb6 however i am using vb 2008 and the code for vb6 does not seem to work.

Then i have a command button underneath which i want to save the content of the rich text box to the rtf file (C:\\stickynotes.rtf). This is so that the user can edit and ammend information.

here is some code i have so far

Dim fileReader As System.IO.StreamReader
fileReader = My.Computer.FileSystem.OpenTextFileReader("C:\\stickynotes.rtf")

Read Byte Array To String

Sep 20, 2011

I'm trying to read a byte array into a string however it's array is filling up from a dll in the following format. [Code] now its decoding the first byte but I think because of the next [0] it's not completing the whole array. This is the code that I'm using:

Radiotext = System.Text.Encoding.ASCII.GetString(szRetRDS)

I did think about writing it into another byte array excluding the [0] but unsure how I would go about this.
