Creating non-text ToolTips in code

Posted By:      Posted Date: September 10, 2010    Points: 0   Category :WPF
I am trying to create a non-text ToolTip in my code like this (where sp is a StackPanel):                 if (helpText != null)                 {                     ToolTip tt = new ToolTip();                     RichTextBox rtb = new RichTextBox();                     rtb.Document = new FlowDocument(new Paragraph(new Run(helpText)));                     tt.Content = rtb;                     sp.ToolTip = tt;                 } This must be calling the ToString() method of the RichTextBox, because all I get in my ToolTip is "System.Windows.Controls.RichTextBox". Can you please tell me what I am missing? Thank you!

Creating Event Handler in Code behind


Hi, so I have a control that is created in the code behind and generates fine but I can't figure out how to create an event handler for it.  I've found plenty of examples for it in C sharp, but none of them seem to apply to VB.  What I want to do is essentially this:

myDropDownList.SelectedIndexChanged = "Event to do here"

but it doesn't seem to work for me.

Any suggestions are appreciated.

creating a code based on the evaluation


I would like to create a simple program, like a game, but so far without any graphical interface. Only a code, supported with some numbers, so that the user will know whats going on in the background.

I was thinking of creating a racing game (like formula 1 or sometihng similar), with available data (attributes) like:

Driver: age, agility, concentration, experiance, stamina,...

Car: engine, chassis, tyres

Smart Tags: Realize the Potential of Office 2003 by Creating Smart Tags in Managed Code


While you may well be excited about the prospect of building managed smart tags, there is little information available to help you create them using .NET. In this article the author fills in the blanks. Along the way he discusses the Microsoft Office Smart Tag List XML schema, advanced managed smart tags for Office 2003 and Office XP, and deploying these features in an organization.

Data from text files, What's wrong with my code?

Hi all, I have uploaded some tab-delimited .txt files on my web site (actually run on my computer, ie localhost, for now), and now I try to retrieve the data from those files. I do this by calling a vb file containg the sub below. Everything works great, except that the sub won't recognise unicode characters. I can split the resulting string using vbnewline and vbtab, but already in the sub in question, the string doesn't understand the Swedish letters åäö, apostrophes and more. Any help would be greatly appreciated! /Pettrer       Shared Function getTextfile(ByVal FullPath As String, Optional ByRef ErrInfo As String = "") As String Dim strContents As String = "" Dim objReader As StreamReader Try objReader =New StreamReader(FullPath) 'UTF8Encoding? strContents = objReader.ReadToEnd() objReader.Close() ErrInfo = Ex.MessageCatch Ex As Exception End Try Return strContents End Function

Rich text field showing html code

I am an end user of Sharepoint. This issue only happens from my computer, not from any other within our organization. What happens is that when I edit an item in Sharepoint that contains a rich text field, HTML code is showing. Like so: <div class=ExternalClassC900CFF4F2BF4312A89133C01A6E3C96> Some text</div> This happens from any web browser. Sharepoint 2007 is used. I have Windows 7 x64. Any idea what is causing this?

Creating mixed logo and text scrolling control

Hello I have a scrolling control that I use for text.   After a while, I switched to a picture combining the text messages and a logo in between.  So the process became: 1. Get message. 2. Get logo. 3. Create a picture of the text messages and the logo in between. 4. Scroll the picture. All was in the plain C# language.   My question is if I can do the same with WPF without creating a picture?   Thanks Eli

Creating path annotations from .NET code


I am to create a bunch of SSIS packages for a customer who wants to maintain these packages afterwards with Business Intelligence Development Studio. To speed up the development process, I have started generating the packages from .NET code.
When I open my generated packages in Business Intelligence Development Studio, one thing is missing: Annotations on paths between data flow components.

For packages created in Business Intelligence Development Studio, output paths for components of type lookup and conditional split are (by default) annotated with "Lookup Match Output" (or "Lookup No Match Output") for lookups, and output name of the condition for conditional splits. This makes it much easier to read and understand the data flow.

I can easily annotate paths for my generated packages if I open them in Business Intelligence Development Studio and change the PathAnnotation property of all paths, but I strongly prefer to do this from my .NET code instead.

My question is: Is it possible to create a path annotation for the non-error output of a data flow component from .NET code? (I should note that error outputs of my generated components are always annotated, not that I am aware of having done anything specific to obtain this).


SSIS Error Text was truncated or one or more characters had no match in the target code page


I the same issue or something close.

Except I have one Field (27) that get a trunacation error


Data conversion failed. The data conversion for column "Column 27" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".

The "output column "Column 27" (91)" failed because truncation occurred, and the truncation row disposition on "output column "Column 27" (91)" specifies failure on truncation. A truncation error occurred on the specified object of the specified component.


Data looks like:Red Text is the field that is throwing the error!
