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)


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.:

Manage A Large Number Of Similar Controls In A User Interface (such As Button Or TextBox Controls)

Aug 23, 2011

There is newer code in a follow up post.  I suggest using the code in the later post rather than the code in this one.  You can still read this post though.  When designing a user interface, one should be conscious of how many individual controls are required to implement the functionality.  In some cases an initial design may begin with many buttons or textboxes (for example) but then further review of
the actual required functionality allows for a reduction in the number of unique controls.

But other times, there isn't a better way (which will still make sense to the user of the application) then to have a series of many repeated controls. So in the cases where one can be certain that the best UI implementation for an application will require the use of multiple copies of a given control, then it often becomes necessary to maintain some method of managing all of those controls at various points
throughout the application.  Doing so typically requires that one build up some collection of controls which can then be accessed by index in order to work with any given control; but this can lead to a lot of clutter in the code file which handles these control's events.  For instance there will be some kind of collection declaration, some recursive routine to find all of the controls of interest, and then any number of event handler methods with long lists of Handles clauses, or additional code loops to wire up the event handling for each control.

Purpose Since most of this functionality could be considered a requirement regardless of the type of control being managed, or its required functionality, it may make sense to wrap all of the control management functionality into a single class.  And since our first requirement is a collection of controls, then a base collection class could be the perfect starting point for our control manager. There are a number of existing thread around this topic, with some recent (at the time of this writing) ones being:[URL]..In this, and related, threads I have posted examples of a simple TextBoxManager and ButtonManager control.  But again, with so much similar functionality required regardless of the control being managed, it would be technically possible to create a generic ControlManager(Of T As Control) class which can manage any type of control.


So in summary, one can facilitate managing a large number of user interface controls by building a "control manager" class which both encapsulates the list of control instances, and deals with adding and removing defined event handlers for every control it manages.  The generic control manager class itself can be inherited and extended into a more specific class on a per-application basis in order to provide more application-specific functionality.

Control Recommendations - Controls At The Top Of It And A Large DataGridView Is Docked Below All The Controls

Nov 10, 2011

I have a maximized form that has controls at the top of it and a large DataGridView that is docked below all the controls. Its kind of like the Ribbon in MS Office. The controls cover about 1/4 of the screen at the top. I would like a way for the user to click a button to hide all the controls then automatically expand into the place the controls were so the user can view more data in the DataGridView and visa versa. For example, in MS Office Excel you can hide the ribbon by clicking a tiny button that has "^" on it.

I'm not very familiar with all the controls in Visual Studio so I would like to hear some recommendations. Is this situation ideal for a SplitContainer or ToolStripContainer or am I way off base here?

NumericUpDown Controls - Update Some Variables Each Time One Of These NumUD Controls Changes Value

Nov 20, 2011

I've got a couple of these NumericUpDown controls I put on a form. Without describing too much about the form I basically want to update some variables each time one of these NumUD controls changes value. So for each NumUD I have a call to a Recalculate subroutine within their "changedValue" event.

There are actually two problems. First, if I initialize the "Value" property to something other than zero in VB2010 at DESIGN TIME it won't even open the form when I hit RUN. It gives me a "No Source Available. No symbols loaded for any call stack frame" error. The error box says "InvalidOperationException" was not handled. So if I try to set the initial value of the Value property to anything but zero of either I get this error.

Forms :: Dynamic Controls Disposal - Only 50% Of Controls Removed?

Sep 17, 2010

I have a query about dynamically added controls to a form. I have a series of buttons which are created and added at run time. I have a two drop down lists and two buttons which are created at design time. Button 1 creates a series of buttons called "Test 1.x" based upon the selection of the two drop down lists. This works fine and am happy with the logic.However.... Button two should remove all the dynamically created buttons from the form.This does not happen. What does happen is that 50% of the buttons are removed starting with the first one. WHen checking the loop it only enters the loop half the amount of times that there are buttons. Very strange. When the loop is run repeatability it will remove all controls. Why will my logic not remove all the dynamically created controls at once? What is wrong with my logic?

I attach two code snippets and the .net file for your consideration.Button method which creates the dynamically created buttons from the two drop down lists and adds to form

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Setting A 'default' Value To Controls (textbox) (loop Controls)?

Nov 11, 2009

I have aspx form with several textboxes.They are populated with values from a table via retrieval of a dataview.If the row count for the dataview is 0, then I'd like to reset the values in all textboxes. How can I loop through all the textboxes and set a default value?I've tried the following, but no sucess.

For Each ctrl As Control In Page.Form.Controls
If TypeOf ctrl Is WebControls.TextBox Then
CType(ctrl, WebControls.TextBox).Text = ""
End If

My first For Loop was using Page.Controls but it returned only 1 count.The textboxes are inside a tabpanel (ajax), so do I have to locate the tabpage and then find all it's controls (for each tabpage)?

Controls Not Return All The Child Controls For The Form?

Apr 15, 2010

I have a slight problem With an enumaration of child controls on a form. The following code will not get but about have the controls that are on the form. The controls show that the count is correct but when it goes through the loop it skips over some of the controls. If you run it through the enumeration two or three times it will get all the controls a few at a time. The solution uses two forms, one that has the controls and the other that labels are made and displayed on. The Tx is just a index to add a number to the and rename the label. So each label is identified seperately. This works for all the the controls that are seen in the for each loop.

VS 2008 Loop Through Controls Doesn't Get All Controls?

Jan 21, 2011

I am rather irritated at this. I have no clue why looping through controls on a form and in groupboxes leaves out 75% of the controls.

Here's the code I have:

Dim settings As String = ""
Dim gbControl As Control
Dim gbbox As Control


I want to have setting save all settings to an ini file, and not have to reprogram the saving routine when I add a group box or control. At random times, any number of controls can be disabled, checkboxes can be checked and unchecked, radiobuttons can be checked and unchecked. Regardless of the state of the control, I want the control to show up in the loop. But they don't. Only controls that are enabled and only checkboxes that are checked, every other control state is ignored. That's crap, and is definitely not what is needed by any programmer of any type. We're capable of determining if a control is enabled, hidden, checked, visible, and otherwise.

How do I get the controls to be included in the loop regardless of their state?

For Each...In Panel1.Controls Is Skipping Controls?

So, I took it a step further in testing...Now I'm really confused about the .controls collection. When I try to delete controls from Panel1 with the below code, it only deletes every other control instead of all controls.

For Each ctl As Control In Panel1.Controls

It looks like it deletes item(0) which moves everything back one step but then advances the pointer to the next step. For example, if the following controls exist on the form...

Manage Controls If There Are Many Many Controls Placed On The Forms?

Dec 10, 2006

I would like to know how do .net developers manage a large window application with a large number of controls, such as textbox , button, groupbox? I have seen a number of people do it this way : declare the controls as an array and initialize them one by one at run time . In this way it is easy to manage those controls because they can be accessed by array index; but this solution seems to require very good understanding of control's attribute such as its location, font etc.  This could be a difficult task if the project is passed on to a less experienced developer and add changes to it.How do you deal with it?

Wiring Controls In VB, Controlling The Controls

Jan 31, 2012

I'm in the middle of using Visual Basic (Visual Studio 2010) to create dynamically created controls. Essentially what I'm doing is creating a label, a textbox, a label (which will act as a stopwatch), and a button (to control said stopwatch). Each set of controls will be arranged (and named) like this in a row: [Code] I've gotten the bit about creating the elements dynamically as well as creating them within in a panel with a particular number attached to the end of its name on the form that I've created. What I would like to do is wire an event for the button that was dynamically created to control the stopwatch timer that was created through the same event. So in short, I'm asking how do you wire an event to control a particularly dynamic button?

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?
