ToolStripTextBox Cut Method Doesn't Remove Text?
Jun 23, 2010
I have a toolstriptextbox and a custom context menu strip with a "Cut" menu item. When you select text in the textbox, display the context menu and select the menu item, the cut method of the textbox is being executed, the text is pushed to the clipboard, but the text is not being removed from the textbox. The code is as simple as follows.
Sub menuItemCut_Click (byval sender as object, e as eventargs) handles menuItemCut.Click
textbox.Cut()
End Sub
I have verified the event is fired, and the selected text in textbox gets sent to the clipboard. For some reason the selected text is not removed from the textbox. Has anyone ran into this issue before when working with a toolstriptextbox?

I am placing 2 of these on my form and want to do the following:
1. When the control is not Focused and the user clicks inside the control, I want to highlight all text within the control. I expect to use SelectAll() to accomplish this.
2. When the control IS Focused and the user clicks inside the control, I want standard actions to occur; i.e., the user can click-and-drag to highlight, double-click to highlight,
3. When the user leaves the control (clicks on something elsle), if the control is empty, I want to populate it with pre-defined text. If it's not empty, leave text as-is.
I'm having problems, though, with figuring out #1 and #3. I have tried Enter/Leave, GotFocus/LostFocus to no avail. With Enter/Leave, the text will highlight the first time a user enters the control, but I can't seem to get the program to think the user has "left" the control. That is, the "Enter" code will not fire again.
I also thought about using the Click event, but I don't want the SelectAll() code to fire for EVERY click in the TextBox controls.

What i need is, if a item in a listbox Doesn't exist, it needs to remove it from the other.
In the pic i have attached. Basically If it doesn't exist in Listbox2 then it needs to be removed from Listbox1 and tell the user which one has been removed.
i.e Test 02 doesn't exist. So messagebox would show "test02 has been removed" then remove it from listbox 1
It probably something simple thats sitting in the back of my mind, but for the life of me can't figure it out lol

to know if a control have any handler. I have a dgv and in the editing control Showing event i add an event handler like this: VB AddHandler e.Control.KeyPress, AddressOf Grid_KeyPress_NumbersOnly This event it's added in some of the columns and for the other ones i remove it... The problem it's when the user, for example selects 3 columns where the event it's added, then if the user selects one where the event it's removed, it doesn't remove all handlers... So i have 2 solutions, when removing i put multiple removes or the other check if the event handler it's added doesn't add again. I prefer this second option, but i don't know how to check if the event it's added?

I have in a menu a ToolStripTextBox where the user can enter a CASE NUMBER to FIND. And I have a ToolStripMenuItem below that says QUICK FIND - clicking this will find the case you put in the textbox. Tabbing out of the textbox puts you at this TOOLSTRIPMENUITEM so that ENTER on the keyboard will trigger the FIND. I want to make it so that pressing ENTER while still in the textbox will trigger that same TOOLSTRIPMENUITEM action. Do I have to trap keypresses or is there a more natural way to accomplish this?

I can't figure this out. I have a bitmap that will be used throughout an application, so I can't declare it with a Dim statement in a procedure, or it isn't recognized as having been declared in other procedures. So I declared it at the top of the form class, two ways. This one works: Private MyBitmap As New Bitmap(622, 461) It makes a bitmap to the exact size of a picturebox I have. But I want to be able to change the size of the picturebox and not have to worry about going back into this declaration to set things up, every time I decide to change the box's dimensions. So I tried this next version, but it doesn't work:

I'm using VB .NET and I know that Union normally works ByRef but in VB, Strings are generally processed as if they were primitive datatypes.Consequently, here's the problem:
Sub Main()
Dim firstFile, secondFile As String(), resultingFile As New StringBuilder
firstFile = My.Computer.FileSystem.ReadAllText(My.Computer.FileSystem.SpecialDirectories.Desktop & "1.txt").Split(vbNewLine)
secondFile = My.Computer.FileSystem.ReadAllText(My.Computer.FileSystem.SpecialDirectories.Desktop & "2.txt").Split(vbNewLine)

I have a ToolStripTextBox on a ContextMenu that opens upon right-clicking a NotifyIcon in the systray that I'm using to 'filter' what is shown in the menu. My trouble is that as soon as the text box loses focus, the menu closes. Is there a way to force the menu to stay open?
I tried changing "AutoClose" to false, but then my menu wouldn't open at all when the NotifyIcon was clicked.

Basically, I want it so if dllA doesn't have a method that the application is looking for, it asks dllB. This is assuming, as well, that ApplicationX and dllB don't know anything about dllA and dllA kind of just appeared out of nowhere (I want dlls dynamically like a patch to my applications without having to rewrite ALL of the methods, properties, etc. in the dll and have everything else just routed to the old dll).

When I've used the remove handler method in my code, I get this warning:The 'AddressOf' expression has no effect in this context because the method argument to 'AddressOf' requires a relaxed conversion to the delegate type of the event. Assign the 'AddressOf' expression to a variable, and use the variable to add or remove the method as the handler.Why do I have to assign the "AddressOf" expression to a variable?

What's the best way to dynamically remove method calls at runtime? Essentially what I'd like to do is pass a parameter to my application. Let's call the parameter level. Depending on the value of level, I'd like to essentially remove all the calls that have higher levels. I have the following but was wondering if there were a simpler/cleaner way to remove the calls:
Ideally I'd really like to write something like:
Log5("message")
And just have Log5 work or not call if it doesn't exist. My goal is to actually remove the call. The overhead for calling level 5 logs that test and return is fairly high and I rarely use it.
Module Module1
Delegate Sub Log(ByVal message As String)
Public Log1 As Log = Nothing
Public Log2 As Log = Nothing

I've got a simple tool written in VB in VS 2010 that has a series of command buttons which run Windows command files and the output is sent to a Rich textbox object on the main form (the comand files take awhile to run so I wanted the output to show up in the RTB as it was produced to show progress). All worked well until I made an update to the tool so that the series of buttons are no longer hard-coded, but created dynamically from information in the app.config file. To do this, I use a button

if they choose to use a networked version of my software, I will need the main server doing the authenticating. This is a problem, because from what I understand, it is quite easy to clone MAC addresses. I have looked into using the CPU ID and the HDD ID, but those are not unique, well at least I don't think so. Reason why I say they are not unique is because someone has the exact same CPU ID as me, and the HDD ID changes from partition to partition (same drive). Maybe the HDD ID is a partition ID instead? Anyways, I was thinking maybe I could get the Physical serial number of both the HDD and CPU, but I have not been able to find anything yet.
