I’m converting some code from desktop app. It is using a library creating an excel file.
here’s the code
dim f as folderItem
f=SpecialFolder.Temporary.Child(filename + ".xls")
dim bstream as BinaryStream
dim writer as new ExcelWriter(bstream) 'spExcelWriter(bstream)
writer.ProcessRecordSet(rs, lsSql, nil, True, lbWeb)
ShowURL(f.Name) <------------------ Compiler error: This item does not exist, Highlighting ShowURL
Anybody have an idea what I’m doing wrong.
It doesnt exist for console apps, which dont have a UI aspect
You can replace it by a shell
Dim s as new shell
On Windows replace “Open” by “Start”. The system may ask which browser to use the first time around.
Because you’re in a Web app you have call ShowURL from a web view (webpage). http://documentation.xojo.com/index.php/WebControl.ShowURL
Oops sorry. What I posted is for Console. Please disregard.
Bob is indeed right.
Problem is, showURL will exit the Web app and terminate the session. It would be better to use a WebHTMLViewer inside a WebPage.
There is an optional property in ShowURL that will attempt to open it in a new browser window. Sadly, there’s no way to know if the user has the Don’t Allow Popup Windows setting enabled in their browser. It then fails silently.
I’m sorry I wasn’t clear. This is a web app and the file that is created I want to download.
In the examples I saw they used it.
I modeled it after:
If TextFile = Nil Then
// Create a text file to download
TextFile = New WebFile
TextFile.MimeType = "text/plain"
TextFile.ForceDownload = True
TextFile.FileName = "TextFile.txt"
Dim d As New Date
d.GMTOffset = Session.GMTOffset
TextFile.Data = "Hello World to " + Session.RemoteAddress + " at " + d.ShortDate + " " + d.ShortTime
// The WebFile.Downloaded event handler is called when the browser
// requests the file for downloading. This code maps that event handler
// to the FileDownloaded method on this web page.
AddHandler TextFile.Downloaded, AddressOf FileDownloaded
// Showing the URL prompts the browser to download it
The big differance if this uses TextFile = New WebFile and the excel file is binary.
So how can the compile sat that it doesn’t exist??
