Is it possible to add a tab character into a textblock? It's a textblock in Xaml, but i'm adding the text in code, so it has to be done there. Is there any action like "Environment.NewLine", but for the "Tab" character?
View 2 RepliesWe have a multi-line control that we are attempting to prevent the Enter/Return key from being used to create a new line.Strangely enough, "AcceptsReturn" as False does not prevent this.So we added the following:
Private Sub txtAddr_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtAddr.KeyPress
If e.KeyChar = Microsoft.VisualBasic.ChrW(13) Then
e.Handled = True
End If
End Sub
This works fine, however one of the QA people discovered hitting Control + Enter still puts in a newline.How would we prevent this?And why does AcceptsReturn being False not work as it appears it should? What is the intended purpose of it?
I'm connection to a sql server 2005 database. I have a field called MapName which contains the following name for example:
SAMWON TEXTILE CO LTD
NO NOT USE
Notice the field contains an enter character.Now in my vb code I have the following
Dim SupplierCommand As New SqlCommand("SELECT OurID FROM [Mapping] WHERE (MapName=@SupplierName) AND (OrgId=" & CustomerId & ") AND (Active=1);", con)
SupplierCommand.Parameters.AddWithValue("@SupplierName", f_supplier)
'con.Open()
[code]....
where the @SupplierName parameter would be:
SAMWON TEXTILE CO LTD
NO NOT USE
exactly the same as my database field.But for some reason this query fails because of the enter characters.

I can't set the FontSize of the Text in a TextBlock, since the TextBox is in a Viewbox. Why?
[Code]...
I can set the FontSizes of all of the TextBlocks but not of the TextBlock which is in the Viewbox.
Look at this simple bug :
<textblock (...) Width="0" />
Working great, the textBox appears to be 0px thin. Works with value like, 2, 3, 4...
Now that is NOT working :
<TextBlock (...) />
<TextBlock.Width>
<MultiBinding Converter="{StaticResource WidthConverter}">
[CODE]..................
Why can i set zero value to TextBox.Width in xaml and not in code behind ? By using a converter, when returing 0, the TextBlock.Width is not set to 0 but to "auto", i can read the text
I have a rather large unilingual application that I have to make multilingual, meaning no resource file.

I can handle that part ok.

Is there a way to animate a TextBlock's colour change?
At the moment I am basically using the enter/leave events to change the colour and I would like to a almost like a fade (but a fast fade, so .1/.2 secs) to give it a nicer visual appearance instead of being instantaneous.

I have a MainPage - mainpage.xaml Inside the MainPage I have a frame that hosts other pages. The first page that is auto loaded is the LogIn - LogIn.xaml
The user enters their email to login (no password required, just email to identify, its an internal app so passwords are not required or even wanted by users).
On MainPage.xaml the header should have a "Hello " TexBlock (name: ui_txbUserName). The LogIn page has a method which on submit gets the UserID (for other reasons and saves it) and the User Name.
I want to change the ui_txbUserName when the person logs in and update if he/she logs out of one account into another. I have looked at INotifyPropertyChanged and Dependency Properties and im just not sure how to go about doing this!

View 2 RepliesWhat I need is some formula to calculate font size of TextBlock for its owner - Let's say I have Canvas height 100.0 then which TextBlock font size should be to fill all space of the Canvas?

I have a very simple StopWatch application in Silverlight. I have the following private properties in my MainPage class: _StopPressed (bool), _TimeStart, _Elapsed (string). I also have a "Start" and "Stop" button. The "Start" button calls a method called UpdateTime that constantly updates _ElapsedTime until _StopPressed is true. When I originally wrote it, UpdateTime would block the UI so I couldn't press the Stop button, so I updated my code to use System.Threading.ThreadPool.QueueUserWorkItem with my UpdateTime method so that it updates _Elapsed on a background thread. That works great at updating the value.However, if I try to set the .Text value of my TextBlock from within UpdateTime(), I get an UnauthorizedAccessException that has to do with one thread accessing the data in another thread.What do I need to do to avoid getting this exception and appropriately update the UI without blocking it?

For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.
