using readalltext in visual studio

Postby Naethyn » Tue Apr 18, 2006 3:44 pm

I am trying to read a multiple line notepad document and display the text in a multiline text box.
Here is the code I am using:

Dim messageString As String = My.Computer.FileSystem.ReadAllText(c:\test123.txt).ToString
infoTextBox.Text = messageString

Unfortunatly if the notepad document has multiple lines it shows as a black square character at the end of each line. It then displays that black character in the text box instead of creating a new line. When I debug and step through the code and copy the black box from the messageString variable and then paste it into a text editor or even visual studio it creates a line!

Any help would be greatly appreciated.

Thanks,
Nathan

Also,
The textvisualizer in debug mode can read the variable with mutliple lines. It doesnt solve the issue of writing it to a text box but it means the carriage control and line feed arent lost in the readalltext.

Translate every char into its ascii char value, then when it gets to the little black box, if its no the correct value for a carriage return, replace it. Probably wont work, but its worth a try.

I found out the problem.

The code above actually works. The reason I was having trouble is because I also tried to save the information to SQL server. After doing what you said, I noticed that the carriage returns where not being saved on SQL. Only the line feeds.

I found this code to add in the carriage returns after saving to a sql server. vbLf and vbCrLf are constants in vb.net

messageString = Replace(messageString, vbLf, vbCrLf)
