View 1 RepliesI 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.
Currently the reports are saved as a html file called report1.html, id like to make the user enter a name for the HTML file upon clicking submit.

Try
'Open new HTML file to be written
WriteHtml = New StreamWriter(Application.StartupPath & "ListHardware.html")
If Not (WriteHtml Is Nothing) Then ' Is the File Open

The other way to do this that I can think of is to save the data that it contains to a file and then load it into the form, are there anyothers? The form has a tab control so printform to file won't help as I beleive I'm right in saying that the tab control won't be usable, as only an image is saved?
