Control XXX Was Not A Loaded Control Class

Oct 13, 2010

I am using .ocx in my project. I made some changes into .ocx. and compiled it. Afterthat I unregistered the old one and register the new .ocx. I changed reference from my project as well. This .ocx is related to display of new form so whenever i m trying to load new form it taking to much time. In .log file of my project i m getting error "control XXX was not a loaded control class"

It seems like its not finding the correct .ocx at the beginning. But afterthat it works fine but very slow.

For Each previewer In LoadedPreviewers
If previewer.GetType().Equals(T) Then

UPDATE: is the following correct?

'True' Control Transparency - Control With Motion Graphics (simplicity, A 'video Player' Control)

Dec 29, 2010

Here's my situation: I have a control with motion graphics (for the sake of simplicity, a 'video player' control) in my project. Think of a PictureBox with constantly-changing images. In front of this will sit a second control (such as a second PictureBox of the same dimensions). The topmost PictureBox will be drawn to in its Paint event.

I need to draw very few elements, and the bottom control is updated much more frequently than I need for this drawing. So these elements are drawn to the topmost control. Think of a news broadcast, where they have live video in the background, with a news channel logo, news ticker, and sometimes gradient visible in front.

I'm trying to create that 'foreground' control, and the closest I believe I have gotten so far is the following:

Imports System.Drawing
Imports System.Drawing.Imaging
Imports System.Drawing.Drawing2D

[CODE]...

The 'Opacity' property in the code above is a sort of "scaling factor." The image drawn to the top control may, in different parts of the image, have any alpha value from full transparent to a full 255. This 'Opacity' property is applied to the entire image being drawn, scaling the alpha values of each pixel.

See the following pictures for description:

.NET Multithreading / Calling Invoke On A UI Control From A Class In A Separate Class File?

May 13, 2011

Example:

Two files - TestClass.vb, myForm.vb

TestClass.vb looks as follows:

Imports System.Threading
Public Class TestClass
Private myClassThread As New Thread(AddressOf StartMyClassThread)

[code]....

The result:Application runs, no errors or exceptions.Displayed is the listbox and the Start button.I press the start button and a msgbox says "Not Invoked" as expected and upon clicking OK to that msgbox "Start Button Pressed" is added to the Output listbox control.Immediately following that the msgbox pops up again and says "Not Invoked". I was expecting "Invoked" as a separate thread is trying to use the Output listbox control.Of course this results in the Output.Items.Add being attempted which results in no visible result as the thread is not allowed to directly update the UI control.

Create A Control Class Rather Than Use A Module For MVC?

Mar 20, 2012

I'm trying to use it in writing VB.NET Windows Form code.So I'm thinking, instead of using a VB.NET module, or having code embedded in the forms, I should create my own "Control" Class, to handle all operations and "application" level variables.Is this the right approach?Ex:

Private Sub frmLogin_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
goControl = New MyControlClass()
goControl.sUserID = txtUser.text[code]....

VS 2005 Custom Control As A Class?

Nov 9, 2009

What I would like to do now is well convert this somehow to a class. so I do not have to DirectCast the items. Is this possible?

Here is the original code that kleinma assisted me with:

Dim CtlLosArray(150) As ShieldLOSInfobox
CtlLosArray(0) = New ShieldLOSInfobox
CtlLosArray(0).Location = New Point(0, 0)

[code]....

Is there a way to make this into a custom class so that I can make things easier to manipulate? at least that is how I think it would be done.

Apr 16, 2011

im trying to access a richtextbox from another class and thread then the ui and i cant seem to get it working. I currently have the sub thats handling the the work inside of a public class and its a sharedsub, im going to be calling it from several different classes and threads but again i cant seem to get it working. the code looks like this. Public Class SharedSubs

[code]...

i would be calling sub using SharedSubs.Console("stringstring") when this is called from the ui thread it works fine but when its called from anyother thread or class its does nothing,ive confirmed it going thru this code but its not displaying anything in the textbox and its not thru an exception due to delegates either which i figured it would.
