Good Custom Calender Control?
Nov 17, 2007
I'm looking for something relatively simple - just a monthly calender view where text can be placed on each individual day - just like a calender on a fridge (with a highlight for the current day). Slap it on a form or UC, set up a few properties and all done. I don't even need any clicking events - just a display.
The controls I've seen for sale are much more than what I need and creating my own, while an option, is something I'd rather not have to spend time on.

How to implement my own events I'm not sure why do I use them. I mean instead of rising event you could simply call functions right? This is as close as I got to a good reason:
1) If you call a function that does one thing and then based on result it needs to do something else it may be a good idea to do that something else in event function that is raised when that first thing was done. This way you avoid creating long functions and can make system more intuitive.
2) If object1 is inside object2 (a variable) and object2 has function DoThis and in that function affect something in object2's parent class it's better to use event in object1 rather than mess with parent (object1) inside object2.

Can anyone point me to a good tutorial for creating custom controls. I want something that is actually understandable.I have gone through a few but nothing really any good at this point. I want to create my own contol that uses its own look and not just modifying a windows control.

I am using custom textboxes and I need to be able to set the Text on txb1 based on the Text of txb2. I have simplied my code to the following:
Public Class customtextbox
Inherits TextBox
Public Event ControlReset()
[Code]....
So, when txb1 looses focus, if its Text is "fried", then it sets off txb2's ProcessAlert function. I had tried to change the value of txb2 Text in ProcessAlert function, but didnt work, so I tried to get it to raise an event instead, which then tries to set the Text property. However I still cant set txb2's Text property. The Text property seems to be set for the duration of the "life" of the Event handler. When I step through the forms controls within the Event handler, the changed Text value is there, but not outside of the Event handler.

Can a custom control NEW Sub be the only one that executes when Inheriting from an existing control please?I am Inheriting from TabControl and I do not want the base New Sub called, is this possible?In other words, I do not want TabPage1 and TabPage2 to be added.A Form has an Activated Sub which runs once a Form is activated.It is a pity that Microsoft have not got such a method in the baseControl Class otherwise I could have used it within a custom TabControl.
Public Class Form1
Private Sub Form1_Activated(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Activated
End Sub

We have a ASP.NET web application written in VB.NET where we build content programmatically during the Init event.We make extensive use of user controls, building them on the fly, and I now want to start including SilverLight content.Is there an easy way of embedding a SilverLight application in a control, and then instantiating the whole thing in code, in the same way as you'd programmatically add ordinary ASP.NET controls to a page?The SilverLight component itself works fine when added to a page using the <object> tag but I really want to be able to reuse it elsewhere in code.Since I'm expecting use of SilverLight to increase in our application, and the asp:Silverlight control seems now to be deprecated, I'm looking for an alternative way of wrapping the content.

What I've done is create a User Control Library (Project) and I've added a single User Control to that project. The control contains a single FlowLayoutPanel, and I created a Property on the control itself to pass the FlowDirection from the Control to its FlowLayoutPanel child.
Build, reference, component appears in the Toolbox and everything works fine, but the property on the control does not appear in the Properties window when I go to edit it at design time.

I want to create a custom control in a dll file.
I can make this without a dll file, also inside a normal project, making a class for it and inheriting the desired base control class, compiling the project and the toolbox has the custom control.
But now I want to make it in a separate file, in a dll file. I use vb express 2008.
I start a new class library project, add the reference System.Windows.Forms to the project and add this code (this is only an example):
Inherits System.Windows.Forms.Button
Private Sub New()
Me.Backcolor=Color.Red
End Sub
I compile the project and get the dll file. Then I add this file to the toolbox, but I get the error message: "this control has no components."

I'm trying to play with this: [URL]..I have no clue how to use it though.What i THOUGHT i had to do was open the project and "build" it to produce a .dll or something which i would then add as a reference in my new project. I'm unable to open the solution so i could not test this theory.
