I can work out the saving bit later.In the attached file you'll see the highlighted bit I want to edit.

Simple question, what would be the optimum code in VB2010 to read in a text file and verify that:1) It is a text file, and2) There are no non-ASCII characters anywhereAnd conversely, we would want the code to provide a warning if the file is not a text file, or if the text file contains non-ASCII characters. [Note that LF, CR and EOF are expected to be in the text file, and should not be flagged as errors]

I am creating a shell for a FORTRAN application which reads a tab delimited text file.Because I am using Excel to manipulate data, is it possible to use the Excel Automation features to "save as" a tab delimited text file?The only method available seems to be a unicode text format, which does not work. Or is there another format that mimics tab delimited so that the FORTRAN application will read such a file without difficulty?
View 1 RepliesI have an asp page with vb.net code that will query a database and present the user with the number of records that exist that need to be exported along with a button to export them. After you push the export button, it will prompt for a location and filename. But after that, it will not refresh the page with the new counts that now exist. Or in this case update the count to zero for the button they clicked.
[Code]
So how can I tell the page to refresh with the new counts. It almost seems like I need to tell the process to wait until after the user has finished finding the location and saving the file but I don't want to add a generic threading.thread.sleep in, I want it to only wait until they are done and then refresh the page.
