I am trying to open a previously created VB Project on my machine. When I open the VB Project file, I get the error-
Line 15: Class abcVBListViewCtrlCtl.abcVBListView of control abcVBListView1 was not a loaded control class.
what could be the probable problem. I am pretty new to this technology.
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.

View 1 RepliesI have two usercontrols. One is loaded statically another dynamically.In the aspx page I can write as follows for static user control.
ProgramAddSchedule.onNewProgram += new AddProgram.OnNewProgramClick(onNewProgram_btnHandler);
But dynamically loaded control's event I am not able to get
Control myUserControl = (Control)Page.LoadControl("~/View/EditScheduleProgram.ascx");
How do I get the event of the dynamically loaded control?
I have the user control that is loaded dynamically. When the user save the data by clicking on the Save button, a raise event is passed.
Public Sub RaiseCloseEvent(ByVal sender As Object, ByVal e As System.EventArgs)
RaiseEvent Close(sender, e)
Debug.Print(String.Format("The control {{0}} was closed by {{1}}.", Me.Name, sender.ToString))
End Sub
In the save button I have called the RaiseCloseEvent as follows:
RaiseCloseEvent(sender, e)
Now, how can I close the user control form? Any Idea? I have used VB.Net language.
I have a webbrowser control and the following code is in a for next loop. If I use wba = New WebBrowser the code works in the background and I don't see the loaded pages in the webbrowser control. My question is how can I see the results in webbrowser component with wba=New WebBrowser ?
wba = New WebBrowser
AddHandler wba.DocumentCompleted, AddressOf wb_DocumentCompleted
TheLoginUrl = Items(2) & "/test.php"
wba.Navigate(New Uri(TheLoginUrl))
results.Text &= "Login to: " & Items(2) & vbNewLine

In my userform I have a WebBrowser control to load PDF files. I have added a FolderBrowserDialog to allow user selection of drives and or folders.
What I am trying to do now is after a file has been selected and viewed, the user may want to change drives and or folder locations. How do I remove the current contents of the WebBrowser control to be a blank screen (just like when the app starts, its blank).
I am just wondering how to force the creation of a handle of a control before the form that it is contained on is loaded... I have tried:
[Code]...
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.
I have two rich text boxes, and two buttons on my screen. The first button grabs HTML from a URL and then converts the HTML to XML which resides in rich text box 1.
The second button is to grab the XML from the rich text box1 and then parse it to grab all the input elements by their ID.
My issue is that my parser isn't doing anything. My guess is that I'm not quite getting the XML from the first rich text box.
What would be the best way to grab the XML from a rich text box load it into memory and then parse the XML to grab all the ID tags?
Here is my code --
Imports mshtml
Imports System.Text
Imports System.Net

View 10 RepliesI tried it and get an error but maybe I'm tring the wrong way. Can a usercontrol inherate an application defined class ie.. could you inheritance a classic rect class into a user control to add the hight and width properties to the control without having to do all the coding all over again? Currently I just declair a private instance of the class within the control and then encapsalate. It would be nice if I could just inherit all the functionality of my classes into controls designed to implament the classes.

View 6 RepliesI'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]....
