I can't manage to display unicode characters in VB.NET.I'm doing this in C#:
string myString = "u03A3"; //upper case sigma (sum)
But it doesn't work in VB and I can't find a way to make it work.
Having trouble with the UPDATE query, it workd perfectly fine when there is no unicode symbol in the textbox but gives me the following error when unicode is present.
Edit:
I am using .RTF format
Syntax error (missing operator) in query expression ''{
[code].....
Is there any easy way of converting a windows-1252 string into a Unicode one?
View 1 RepliesI have developed an application and need to allow users to enter text in any language and save it to my database. However the text is saved as '?' in my database. I have googled quite a bit and found that people have suggested not to use varchar, text types but use nvarchar and ntext etc in your database. I have gone through and made these changes to my database. However it still saved text as '?', I then found people where saying about adding 'N' infront of the text prior to saving into the database. The problem is that I cannot figure out how to do this in a stored procedure.
Stored Procedure
Code:
CREATE PROCEDURE [dbo].[spUpdateActionTaken] @ID as varChar(4),@action as text,@modifyDate as varchar(50)
AS
UPDATE commentsTbl SET commActionTaken=@action,modifyDate=@modifyDate WHERE [ID]=@ID
Note: Fields commActionTaken set to nText
VB.Net Code
Code:
Dim actionTaken as String = Me.textBox.Text
Dim myCmd As New OleDb.OleDbCommand("spUpdateActionTaken")
myCmd.CommandType = CommandType.StoredProcedure

I made a batch script using VB.NET which deletes shortcut on my desktop. The problem is that shortcut title contains unicode characters so batch doesn't work. However if I remove that unicode character from the shortcut and batch script it does delete the shortcut. How can I make it delete the shortcut w/o removing that unicode character?
tempstring = "@echo off"
tempstring = tempstring & vbCrLf & "del " & Chr(34) & My.Computer.FileSystem.SpecialDirectories.Desktop & "My shortcut™ 1.lnk" & Chr(34)
tempstring = tempstring & vbCrLf & "del %0"

View 1 RepliesHow do I Extract all Characters in Unicode, UFT8,iso-8859-1 to 9 etc to a list or array In VB?I have a SQL Database of which contains values from 51 languages. I need to detect which ISO-8859-? Was used to encode the string value. For example Turkish Characters i.e. "Ö Ş ş ğ ü Ç" Once I have the correct ISO, I need to convert the Chars with-in the string to Unicode using only if the string value contains values that are not UFT7, and convert the string to HEX?The reason I need to detect the ISO etc is because we are sending SMS, of which jump from 160 characters to 70 if a special characters are used, i.e. "Ö Ş ş ğ ü Ç" Is there a simple way to extract the ISO-8859 Character Set to a Array etc, or is there a simple way to check if the character exists with a ISO-8859 data set?

I basically know how to display ASCII code in a text box, but I'd like to be able to display Unicode in a text box.
The data was being read from a Gridview which had the html encoding. The solution was the following...
Dim Sht_Text As String = HttpUtility.HtmlDecode(row.Cells.Item(0).Text)
I am trying to prevent from having to escape apostrophes and other special characters in my string variables by using a parameterized query with an OleDbConnection. I have all of the parameters in the same order, the insert is working, it just does not maintain the characters. I keep getting those pesky html codes. I am trying to insert into an Access db from a web pages. As I mentioned, its working, just not the special characters.
Here's the code:
Dim pConn As New OleDb.OleDbConnection pConn = New OleDbConnection(cb.ConnectionString)
Dim SqlString As String = "INSERT INTO Strings (Mlt_String_ID, Lng_ID, Strg_Name, Sht_Text, Lng_Text, Alt_Text) Values (?, ?, ?, ?, ?, ?)"

jp and en records already existed, the insert of fr record pushes the html codes for the small circle which represents the degree symbol. Happens for all other special characters as well.
Outlook is causing some problems when being passed a mailto string with accented characters in it. Changing the codepage for my entire webpage that has this string on it solves this problem, but that causes other problems in the system, so I would not like to do that.
A string like such returns a lot of garbage characters:
"mailto:Helpdesk-someemail@email.com?subject=Mon bâtiment / Départementé / Bureau n'est pas répertorié"
Meanwhile, this cuts off the character after the "D"
"mailto:someemail@email.com?subject=Mon bâtiment / Départementé / Bureau n'est pas répertorié"

Setup:
Windows 7 Ultimate with All Language Packs Installed
Visual Studio 2008 Winforms VB.Net project.
I'm in the process of localizing this project, and when I'm making the Japanese version of the forms, the characters display as squares, though they render in my browser correctly. I'm guessing that this is because the default font does not have a glyph for those characters.So, my questions:
Are winforms UTF-8, or some other character encoding?
Is there a way to change the character encoding?
Should I change the font for the Japanese forms, or will Windows do it?
What's the general best practice here?
I want to know that I am copying the characters correctly into my forms, and I want to be able to test them.How can I do this?
Arial Unicode MS does have all the glyphs, but I wasn't using it, because it wasn't in the VS2008 list of fonts. I manually edited the font box to use it, but then Visual Studio throws the message, "Attempted to read or write protected memory. This is often an indication that other memory has been corrupted." I'm guessing that's because VS doesn't have permission to access that font for some reason. I go back to the default font, scary error message goes away.
Then, even when using Arial Unicode MS, the text renders as blocks in the forms titles.Same text renders correctly in labels.I think I want to use the default font, and let Windows handle it. I think I've read that everything from XP on will handle it. Windows 2000 won't, which is a shame, but what ever, I don't know what font I should use, and whatever font it is was excluded from VS.I don't know how to add it without getting lots of error messages about protected memory.Now the problem is, resizing the labels in the form, since the translated text is often larger.
Also, I don't have a support team to do this for me, but I could maybe install extra copies of Windows 7, and change to the Japanese language pack and try to run it.But that becomes a major pain.I thought I read that you could change the language while the application is running, but that doesn't seem to be true.MS docs talk about how to do this, but Windows 7 also tells you that you have to log out to change the language.MS Gothic seems to work, and it's part of VS 2008, but the title bar is still squares. That's really odd, since the same glyphs are in the winform.Is that because title bar fonts are set at a system level, and not the application level?

I have a label in my form which displays the text-content stored in a text file. However it is not able to display special characters like ", ', : etc. Instead it just puts a small rectangular box (same size as that of the text).
How do I get them to display these characters? Should I not use text files in this case or do I have to turn on some control-properties?

I wrote a small VB6 program to monitor the status of a Shared Network Drive. In this case it's an external hard drive. The drive is used for backup. The program is invoked automatically when the computer is booted and runs minimized.
If the backup drive is not turned on or otherwise not functional then the program changes from minimized to a normal window and displays various statistics and a warning that the backup drive isn't working.
I want to make the warning much more prominent, like minimizing the program that happens to be running or displaying the warning window in front of the progrmam that happens to be running. I want something really noticaeble. The computers don't have speakers so I can't play an warning.wav .

Using data binding and ado i am controlling a listbox selection (draws from an access database) based upon a combobox selection. Problem is i want to display more than just one column.The code i am currently using specifies the displaymember and value member on form load. However, i cant seem to be able to specify multiple display members.
Heres the code i am using on load.
Bindingsource1.datasource = a_dtBuilding
Listbox1.datasource=Bindingsource1
Listbox1.displaymember = "Building"
Im sure this is easily solved although i have read i should use a listview instead of a listbox for this.
