You are probably either using an encoding that doesn't support the characters, or using different encodings for saving and retrieveing the text. Where do you save it? Text file? Database? Left pocket? Does the value change when you save it or when you retrieve it? -- Göran Andersson _____
Hi all,
When a user enters a german character in a textbox (such as ö ä ü ß) and I try to save it, these characters get converted to a different character. How can I prevent this? Tia, Martin
Hi again,
The code Im using to read the file is I think pretty straightforward: Private Sub DoOpenFile(ByVal ThisFile As String) Dim Line As String Try Dim sr As System.IO.StreamReader = New System.IO.StreamReader(ThisFile, True) Line = sr.ReadLine() sr.Close() Catch Ex As Exception MsgBox("Error reading file" & Chr(13) & Chr(13) & Ex.Message, MsgBoxStyle.Critical Or MsgBoxStyle.OkOnly, "Error") Exit Sub End Try Line = DoFormatLine(Line) FillEditor(Line) FileName = ThisFile Editor.ReadOnly = False Me.Text = "Editing " & FileName End Sub The text is created in an editor (MultiEdit) and looks like this: FTX+AAK+1++Es bestehen Vereinbarungen, aus denen sich nachträgliche Minderungen :des Entgelts ergeben können.+DE When I open this in my app, it suddenly looks like this: FTX+AAK+1++Es bestehen Vereinbarungen, aus denen sich nachtr�gliche Minderungen :des Entgelts ergeben k�nnen.+DE After your message I added the TRUE parameter in the streamreader (detect encoding) and set the form's language to German... To no effect. Tia, Martin [quoted text, click to view] "Göran Andersson" <guffa@guffa.com> wrote in message

Hi Herfried,
Thanks a lot. Adding the parameter System.Text.Encoding.Default did the trick! However, I also do a rewrite with the SreamWriter. I assume I need to add the same parameter there? Martin [quoted text, click to view] "Herfried K. Wagner [MVP]" <hirf-spam-me-here@gmx.at> wrote in message

Hi Göran,
Thanks for your reply. I'm saving the texts to a text (ascii) file. I'm not using any special encoding, in fact I don't have any experience using other character sets, so I am not aware of how to choose a special kind of encoding... Any help would be greatly appreciated.

The ASCII encoding doesn't support any special characters. You should use the UTF-8 encoding. This is however the default for the methods in the framework when you don't specify any encoding, so you have to have done something to use some other encoding. What does your code look like? -- Göran Andersson _____

Thus you have to use another encoding. 'StreamWriter' uses UTF-8 by default which can contain umlauts. So, do not pass an ASCII encoding object to the constructor. -- M S Herfried K.

Most likely the other application stores the file using the Windows ANSI encoding with the system's default codepage. In order to read the file, pass 'System.Text.Encoding.Default' to the 'StreamReader''s constructor or determine the encoding for a certain codepage using 'Encoding.GetEncoding'. [quoted text, click to view] > After your message I added the TRUE parameter in the streamreader (detect > encoding) and set the form's language to German... To no effect. Well, detecting the encoding isn't always possible because byte sequences contained in the file may be valid for different encodings. -- M S Herfried K.

Save the file as UTF-8, and you should have no problems reading it. -- Göran Andersson _____
Martin,
I have made a simple program to test it. (Dutch settings) Imports System.io Public Class Form1 Private Sub Form1_Load(ByVal sender As _ System.Object, ByVal e As System.EventArgs) Handles MyBase.Load TextBox1.Text = "ö ä ü ß" Using sw As New StreamWriter("C:\TestFile.txt") sw.Write(TextBox1.Text) sw.Close() End Using Try Using sr As New StreamReader("C:\TestFile.txt") TextBox2.Text = sr.ReadToEnd sr.Close() End Using Catch Ex As Exception MessageBox.Show(Ex.Message) End Try End Sub End Class This gives in textbox2 the same characters as in textbox1 Probably have you played a little to much with the language settings of your system.
