I am writing a Windows form application where a client has the ability to add as many chart as needed in the form by clicking at an icon in the menu bar at run time. These charts will have the same format, and I will have them linked to a text box for the client to select which entity to chart.I have no clue where to start. I did a web search and I have found articles that show how to add user's control at design time (I don't think it is what I want).

I also dont want the color buttons to remove any other formatting from text (like bold, underline, etc) - i achieved this for the other buttons like so:

I need my app. to Create an Control Array at runtime that will consist of up to 50 Data Bound Labels. The app. will first be checking the 1st database field (Ing1) to see if there is data, if so then only create the 1st Data Bound Label (lblIng1) and then check the next field and so on.
The problem is that VB 2008 dos not seem to support Control Arrays. There must be another way to work around this.

I have a DataGridView in one of my form which at a certain point I resize an change it's position. I would like to be able to restore it to the designer's default position at runtime.

I have a very simple setup, single mycontrol.ascx with assoicated mycontrol.ascx.designer.vb and mycontrol.ascx.vb file.
mycontrol.ascx embeds a single reference to a custom control: "MyMenu":
<mM:myMenu id="myMenu1" runat="server" />
This has created a protected reference in the mycontrol.ascx.designer.vb file:
Protected WithEvents myMenu1 As Global.CustomControls.MyMenu
Now, when I breakpoint the Page_Load() event of mycontrol.ascx, and inspect the members returned from the type via:
Me.GetType().GetMembers()
I cannot any reference to myMenu1. If I look at the control with intellisence, the property is accessible:
Me.myMenu1
what I'm missing and what I need to do to access designer created properties at runtime through reflection?

View 4 RepliesI'm using Visual Studio 2005, net framework 2.0, Microsoft Internet Explorer ver 7.0.5730.13. Create a form with the webbrowser control and two buttons. Use the code that i provided at the end of this question to understand the scenario. As far as i know, this behaviour happens only on the myspace.com web site. 1. Navigate to your myspace.com inbox page, read a message and click on the reply button to reply to the message. The page will show correctly in the web browser.2. Then click on Button1, repeat the same process (read a message in the myspace.com inbox, click on the reply button), and the textboxes where you have to enter your reply will be gone.3. Then click on Button2, repeat the same process, and the page will show correctly in the web browser.4. Then comment out or remove the oDoc_MouseDown event, click on Button1, repeat the same process, and the page will show correctly.Why does the page shows correctly when the oDoc_MouseDown event is removed? The same behaviour happens if you use any other event of the oDoc variable.I desperately need the page on myspace to be shown correctly with the oDoc_MouseDown event and other events of the oDoc variable.
