Can Not Delete Control in VS2010 - vb.net

At the top of the Properties Window in VS2010, I can see a list of all of the controls on my form. In that last, I see "PictureBox1," even though I don't see a corresponding PictureBox in the Form window.
I can change the location and size of the PictureBox, and set its image to a picture that should be noticeable. I still see nothing on the GUI form. If I can't find something to click on the GUI form, however, I don't know how to get rid of this superfluous PictureBox.
Is there some backdoor method that I can use to get rid of this PictureBox? It seems if the Properties Window lists it, it should offer some method to delete it.

A simple explanation is that it is covered by something else. Use View + (Other Windows) + Document Outline to see it. You can drag+drop it back on top. Or just right-click + Delete and its gone.

How can you add an image to a listbox in VB?

I am wanting to add an image to the top or background of a listbox. I would like it to be visible on the screen, but more importantly is that it prints. Can someone help me with the code for this. I tried to see if you could add it through properties and don't see that option. I need the listbox not listview. Also I was wondering if it could be added as a string and the file referenced at the top of the listbox (when you right click the little arrow and click edit options? Can someone please help. I am working on a project and still very new at this.
You need to create a custom ListBox class and add the ability to draw a custom background by overriding the OnPaint event, like on:

can i make a window form(common controls) using code in vb.net?

instead of dragging and dropping a common control in vb.net, is there a way to hard code it?
or is there a way for me to be able to view the codes where a dragged and dropped object has
been created? thank you so much!
The auto-generated code is intentionally hidden in the VB.NET IDE. But you can easily reveal it. Click the "Show All Files" toolbar button in the Solution Explorer window. You'll now see the Form nodes in your project displayed with a triangle. Click on it to reveal the Designer.vb file. And double-click that to see the code.
Observe the changes in the InitializeComponent() method as you use the designer to add/remove/edit controls. It isn't perfect code, the machine generated it, but it gives you a major leg-up on what kind of code you need to write to "hard-code".

Can't View VBA Form

So I created a form, and have been using it for a while.
All of a sudden today it stopped working. Other forms load and can be viewed but not this one.
The weirdest part is that the controls still respond!
So I can't actually see the form but I can still interact with it. (only using keyboard no mouse clicks are responding) I know the form is enabled. But I simply can't see it! I have restarted excel, and the whole computer.
I even completely removed all code in the userform to see if I could get the blank shell to load, and while I can tell it loads (it disables everything in excel until I use Alt+F4) it still won't be visible. I have checked the Enabled, All Colors, Captiuon, Width, Height, Top, Left, StartUpPostion, SpecialEffect, Zoom, DrawBuffer properties and everything is fine.
I have also Exported and reimported it and still simply nothing. Also tried importing it into another Workbook, nothing. I at my wits end (not that it's very far to reach!)
Also, I can still see the userform in the designer I can still edit it, I get NO errors. This happens not only when calling the form in code, but even when running it right from the designer.
Any one ever have this issue? Any ideas or solutions?
The issue ended up being the Top and left properties. While I did check them, they way I checked them was not accurate; I still have no idea why, but I think it defiantly has something to do with dual monitor setup.
The way I tested double checked the forms top and left properties was by creating a new form and adding a button on the button click event I had a msgbox show the top and left properties of the form at time of clicking.
I then moved the new form to where I wanted the form that woudn't show to be and clicked the button; I then set these values to the form that wouldn't show.
I tested this location and made sure to match the properties with the values I wanted multiple times and it didn't work.
For some reason the values needed where about 1000 digits off (instead of 250 I needed to use 1250) even though I had set the form right where I wanted the new one to be and made sure to save the properties when they matched what I wanted

How to stop my tools strip menu items from appearing in the taskbar?

I have a program which runs mainly though a NotifyIcon in the bottum right of my windows screen (XP). Whenever I open the ContextMenuStrip that appears when the icon is right clicked, a box also appears in the task bar. I also have nested menus inside the menu (mouse over one item leads to another menu), and each additional menu also creates a taskbar box upon appearing. So once I am at the third or fourth nested menu, there would be 3 or 4 windows appearing in the taskbar. After the menu disapears, so do the windows in the taskbar.
How can I stop the taskbar from displaying boxes to represent these menus? I have done nothing in my code as far as I know to create this type of behavior. I have searched for similar problems but have found nothing similar. There is no "showintaskbar" property for these items as far as I can see, and no other property that I can find which would affect this. I have investigated the owner of the contextmenustrip since I read the owner may effect these type of behaviors, but that doesnt seem to be helpful as there isn't an owner property of the contextmenustrip.
I don't know what else to search for, so I am here hoping someone can give me a clue as to what else may effect this type of behavior.
Any help is greatly appreciated. Thank you!
If you are using the ContextMenuStrip.Show() method, it will display in the taskbar as you describe. Try assigning your menu to the NotifyIcon.ContextMenuStrip property instead.

How to always display a control on the currently active tab of a TabControl?

I have a tab control with two tabs. Both tabs have controls which are unique to them, but there is one control which I would like to always appear on whichever tab is currently active.
I figure I just need to add some code to TabControl1_SelectedIndexChanged().
I tried
MyControl.Parent = TabControl1.TabPages(
TabControl1.TabPages.IndexOf(TabControl1.SelectedTab))
MyControl.Parent.Update() ' is this necessary?
and I also tried
TabControl1.TabPages(
TabControl1.TabPages.IndexOf(TabControl1.SelectedTab)).Controls.Add(SeMyControl)
but neither worked (the control moved once, but when I went back to the original tab, the control did not appear there.
googling found someone suggesting
TabControl1.TabPages(TabControl1.TabIndex).Controls.Add(MyControl)
but that looks dodgy as the control is never removed from the old tab, so repeated switching would probably add the control multiple times.
I feel that I am close, but not quite ... how do I do it?
No, that works fine since Controls.Add() changes the Parent property. Which automatically removes it from the tab page it was on before. A control instance can only have one parent.
The more straight-forward approach is to simply not put the control on a tab page but leave it parented to the form which a lower Z-order so it is always on top of the tab control. The only problem with that is that the designer will hassle you. It automatically sucks the control into the tab page when you move it on top of the tab control. One trick to fix that is to leave it off the tab control and change its Location property in the form constructor.
Using your second code snippet that you are concerned about because it doesn't remove it from the original tab, why not just remove it from the original tab before you add it to the new tab?
Maybe something like: TabControl1.TabPages(TabControl1.TabIndex).Controls.Remove(MyControl)
