Inserting Controls Into RichTextBox?

May 13, 2009

I'm building an application that for all intents and purposes is a specialized word processor of sorts ?I am looking for a way to insert custom controls (user controls) into the RichTextBox. I have already tried:Methods used to insert images into RTBs using the clipboard:

Dim imagePath As String = OpenFileDialog1.FileName
Dim img As Image
img = Image.FromFile(imagePath)
Clipboard.SetDataObject(img)

[code]....

Neither work. I'm looking to insert a control into a RichTextBox so it is essentially part of the text. I'm well aware a modified RTB may be needed, but I can't seem to find an appropriate way to do this.

Inserting A Unicode Character Into A RichTextBox?

Mar 24, 2011

I want to insert a special character into a RichTextBox. The character is in a Medieval Latin font (Andron) which is installed on my machine.

When I open MS Word and select Andron as the font, then go to Insert Symbol, then scroll down till I find the symbol I want, I see that its Unicode value is A752, selecting it inserts it into Word OK.

Now, back to my VB2005 project: I have a RichTextBox on my form, and the Font is set to Andron. I have two buttons on the form. Behind the first button I have this simple

RichTextBox1.Text = RichTextBox1.Text.Insert(RichTextBox1.SelectionSta rt, "a")

Clicking this button simply inserts the letter 'a' at the insertion point, fine.

Behind the second button I have this

RichTextBox1.Text = RichTextBox1.Text.Insert(RichTextBox1.SelectionSta rt, ChrW(&HA752))

However, on clicking this button I get the ubiquitous square symbol, as if it cannot find that character, which is odd (to me) as the correct font is selected for the RTB, and that code is the correct code for the symbol I want.

Edit to add: I can now see that all characters up to Ascii (Decimal) 255 (which equates to Unicode 00FF) all display OK, but any value over that does not.

Inserting Line Breaks In RichTextBox?

Nov 27, 2009

I got a program that generates 4 strings which I want to output to a RichTextBox. Getting them there isn't the problem, its getting them on separate lines I am puzzled with. As of right now, they are all just lined up one after the other, which isn't practical for what I need. I simply need 1 output per line, i.e.:
Output1
Output2
Output3
and so on.
How to insert line breaks?

Posting Data To A RichTextBox On A Form From External Objects

Apr 13, 2010

Background: My VB .Net application is a back-end solution that works with a proprietary Linux-based middle-ware messaging architecture developed by our company. My application references to the middle-ware DLLs, obtains connectivity, and subscribes to specific broadcasts with the middle-ware. When the broadcasts are received, it handles processes them and inserts/updates certain tables in a database. To do so, it has specific notification classes to handle each type of broadcast. These classes adhere to the inheritance model imposed by the middle-ware DLLs.

Child Objects Raising Events In Parent Objects?

May 1, 2009

long story short, I have created a ListView type control, using UserControls for the parent control and the ListViewItems. Most the of the control is written and works fine, right up to the point where I tried to replicate the 'Control.SelectedItems(0).Index' property and the 'SelectedIndexChanged' event.

Each child object knows its index value, and could pass this value via the SelectedIndexChanged event (assuming this is how it works in a normal ListView control -- user clicks on an item, and that item fires an event updating the selected index value in the parent object).

How does the child object raise an event in the parent object? I have a feeling this could be done with Delegates, but I'm still learning about their usage.

Multithreading - Create Custom Objects/list Of Custom Objects In .NET?

Jan 24, 2010

I need two seperate lists, which every item is Integer, String, Bitmap - and one which every item is Integer, String String. However I don't know how to do this, or even where to look - I've googled for custom objects and custom object lists. What I'm trying to do is this.Custom Object1 is Integer, String, Bitmap Custom Object2 is Integer, String, String

In one thread I'll be adding items to List1(Of Object1), and processing them, and adding the results to List2(Of Object2), however I need to be able from other threads to look at the list and say only give me the items where Integer = (my thread ID), is this possible? Any help, or even links to information that would be relevant to this request would be helpful?

Many To Many DB And Inserting

Jun 25, 2011

I'm trying to do an Insert into a couple tables on one form with data controls. The problem is I don't know the approach. You see, the client has books to sell. He has catagories and he wants to add many catagories for each book. One or more catagories. It would seem to me that this is a many to many normalization. Being that one or more catagories can belong to one or more books? If this is incorrect, please tell me, as I thought it was a one to many earlier with one book having one or more catagories? Anyway, I need to be able to allow the client to enter one book, and then assign one or more catagories? He wants the potential buyers to be able to query books by catagories obviously. Wondering what approach to use? What data controls, and is it possible with just the controls, or do I need to write a stored procedure to grab the ID from the book using the @@Identity SQL statment?

Inserting A New Row To Database?

May 7, 2009

My problem is when I try adding a new appointment I get an error that says ""Column 'AppID' does not allow nulls."" Editing existing appointments is fine and it updates the DB no problem. I don't have an INSERT statement right now (which might be the issue) so I was thinking of doing this: INSERT INTO [tablename] ( [column1], [column2], ... ) VALUES ( [value1], [value2], ...) Only problem with that is I would need to use the textbox names for the VALUES, and that form that pops up to gather appointment info is from a third party, and I can't find the names of any text boxes
