Return Two Menu Tabs Using System.Windows.Forms?
Mar 25, 2012
I am trying to return two menu tabs using System.Windows.Forms. I have tried using an array and tried using control.add but I cant seem to get this working. What am I doing wrong?
Public Function MonitorsInit() As System.Windows.Forms.TabPage Implements LabTech.Interfaces.ITabs.MonitorsInit
Dim TP As New Windows.Forms.TabPage("Ticket")
Dim TP1 As New Windows.Forms.TabPage("Ticket1")
TP.Controls.Add(TP1)
Return TP
End Function

I have a windows forms application written in VB.NET which scrapes information from serveral web pages (who doesn't right)? Anyway, I am having problem with one particular site where partway through the page navigation my application hangs. When I press pause (or break) in the debugger, it stops on a call to System.Windows.Forms.Application.DoEvents.
Resuming execution shows that it really is stuck on this line (it does not reach the next line of code). It also hangs about the same point each time I run it (at least its consistent). Since System.Windows.Forms.Application.DoEvents yields to other threads on the same processor and then resumes execution of the current thread, I think the problem is that some other thread is not behaving well (not returning from some event handling code). I thought Windows 7 was pre-emptive, which makes me
doubt that theory but I really don't know.
[Code]...
The program scrapes somewhere between 12 and 14 pages before it gets stuck on the call to DoEvents. Does anyone have a clue why this would happen? Why would any call to DoEvents hang?

I have a panel with some controls in it (several textboxes, a slider, 2 buttons, and a small groupbox).. When I click a button, I want all of the textboxes within the panel to be readonly... So I have this code: [code] When I run it though, I get the following error:Unable to cast object of type 'System.Windows.Forms.Button' to type 'System.Windows.Forms.TextBox'.If I remove a button, it moves on to give me the same error but for a label..

I noticed that adding a MenuStrip (from the Toolbox) to my form design doesn't yield a menu bar like many native Windows applications. Instead I get a menu bar like Visual Studio's own. None of the style settings for MenuStrip appear to mimic the much more common native menu bar.Is there a way to add a menu bar to my Windows Forms application that looks the same as the one you see in Notepad, Task Manager and others? (Preferably with the designer, but I wouldn't mind adding it programmatically either.)

When I do this
Public Class cInherits : Inherits Panel
I get this: Base class 'System.Windows.Forms.Panel' specified for class 'MenuButton' cannot be different from the base class 'System.Windows.Forms.UserControl' of one of its other partial types.
How do I inherit?

I am looking to create a menu system in vb 2010 windows app. See attached file to give you an idea of what I want to achieve. I could do it by creating 4 buttons and have 4 panels. when button one is pressed make panel one visible and hide other 3 panels, etc This just seems messy. Will any of the built in VB menu components do this?

Win7 64 bit; fully patched VS2008 targeting FW2.0; VB.Net; running in Debug Mode (not tested in Release mode)I have a resonably complex app which I am refactoring a bit. As part of that, I relocated some code from a subroutine into a Click Event Handler. The Event Handler will, late in the handler, call the, reduced in function, subroutine. The point of this is thatNow when I click the button associated with the modified Handler I get:A first chance exception of type 'System.AccessViolationException' occurred in System.Windows.Forms.dll<br />With Error System.AccessViolationException Attempted to read or write protected memory.This is often an indication that other memory is corrupt.
at MusicManager2009.frmMain2.cmdLoadAlbum_Click(Object sender, EventArgs e)
at System.Windows.Forms.Control.OnClick(EventArgs e)
at System.Windows.Forms.Button.OnClick(EventArgs e)
[code].....
All functions of the app, except those that start from the buttonclick in question, work as before in the problem version.The problem persists after rebuilding the entire solution, after restarting VS, and after rebooting the PC.

It works, I click the little arrow, the context menu appears:I click the menu item, the event is fired, the control is docked:but the menu description is not updated or refreshed (it should show "Undock from parent container"). Then if I click outside the control to deselect it and then I click back on the arrow to show the menu, the right menu item is displayed:How do I refresh the menu items?

This context menu is pops up where the user right clicks inside a dataGridView
When adding the items the VB code is
Dim m As New ContextMenu()
m.MenuItems.Add(New MenuItem("Disassociate *A* Device"))
m.MenuItems.Add(New MenuItem("Purge Device Assosciations"))
Is there no simple way to reference a resource to add an icon to said menuItems?
Pseudo

I've search the net in order to create a custom control but nothing I find is worth looking at, The main thing I want to do is create a skinengin via DLL and import it in my vb 2010 then using or creating some sort of skin builder where I can create a full setting file which contains all the details of the customization regarding the Form(Look, Feel and the controls such as a menu), I have used Iriskin and multiple apps doing this for me and when a user installs my application they still recieve a message about buying the registered DLL file, I would like to create it completely from scratch.
