Prevent A Context Menu From Showing?
Jun 18, 2010I want to stop a context menu from showing if nothing is selected.
If lvCopiedText.SelectedItem Is Nothing Then
cmsText.Close()
End If
That doesn't work for some reason, i think its because that happens before the menu actually appears.
Asp.net - Prevent Numbers From Showing In Exponent Notation?
Oct 21, 2009I've got an app that sometimes stores some decently small numbers, such as 0.000023425. These numbers get loaded up in TextBox controls for users to edit.
Dim number As Double = 0.000023425
someTextBox.Text = number.ToString() ' Shows "2.3425E-05"
As mentioned, the text that shows is 2.3425E-05, which isn't exactly intuitive for the user to see, plus I have numbers even more precise (out to 19 decimal places). I would like the output to be fixed point. Of course I could easily and cleanly do:
number.ToString("F20") ' Shows "0.00002342500000000000"
But then there's an annoying number of zeros left over. So, to fix that, I could do:
number.ToString("#,##0.####################") ' Shows "0.000023425"
Which is what I want, but is there any better way to do it than to have that giant ugly format string there? So, ok, it's not that ugly, but surely there's a different way, right? My goal is to show the raw value being stored in the DB in a friendly way, and I would rather not have to force a format on the number at all.I found that changing the underlying datatype to Decimal solves the issue.
Dim number As Decimal = 0.000023425
someTextBox.Text = number.ToString() ' Shows "0.000023425" instead of "2.3425E-05"
So it sounds like Doubles aren't precise enough to be displayed normally?

View 5 Replies[2005] - User Controls - Prevent Them From Showing Up In The Toolbox
Feb 1, 2009I have created a series of custom user controls for a wizard interface that I am making. Each user control represents one step in the wizard and really shouldn't be used outside of the wizard. The thing that is bugging me is that each wizard step user control shows up in the toolbox of components to insert into a form.
Is it possible to hide a user control from the toolbox? Better yet is it possible to hide a user control from other classes not in the same namespace of an assembly? Is this a good approach or should I think of a different approach?

I'm not getting a remainder like I would have hoped. I'm new and I'm sorry for the lack of intelligence on the subject. To my understanding the Val( function will convert the string to a number, but when I divide it gives me a single number instead of an integer.

Feb 2, 2010You developing a application named "DemoSoft" which is going to be a shareware or Premium, you use different DLL's in this project and some DLL's are owned by you, they are very useful and valuable, you are selling this software and are charging the customer for what the software does but since this software uses one of your Valuable DLL, actually few functions from it you have to deploy it and cannot additionally charge for the whole dll. since that would be unwize.now i want to ask what can you do so that This DLL in "DemoSoft" cannot be exploited, meaning end user could use my software but if some thief tries to use my supplied DLL in one of his own app he is unable to do it, in simple terms DLL should work only and only with DemoSoft.

I want to create a security tool, but can't seem to find this anywhere.This is in vb.net.I know the registry is stored as files on your computer somewhere, but I have no clue where it is stored, though I could probably use a FileSystemWatcher component to check it.Then, for prevention, would simply duplicating the registry files and rolling back the changes work?

How To Prevent Program Being Started Twice
Apr 8, 2010I have a small problem with my application. When the system starts up, the program starts with it, but runs hidden (registry key with paremeter). The program also has a GUI.I want it so that when the user clicks the desktop icon, it does not start a second instance of the executable, but instead reveals the currently running background process. Is that possible?i.e. when the application is started with the "-startup" paremeter, it loads a hidden form2, and closes form1. When the desktop icon is clicked, it loads form1, while form2 remains hidden.

Prevent A Keypress In Another Application?
Mar 17, 2011We have 2 apps that we display at once for data entry. 1 taking up the left side of the screen, and 1 taking up the right side.
1 of those apps is the data entry application. The other app is for viewing scanned info. But they can't talk to each other directly.
So I'm creating a tool that runs in the background to intercept certain keys.
I want to be able to capture keys such of Ctrl + Home, Ctrl + Page Up, etc from the data entry application, and send it to the scanned image to rotate it or zoom, etc.
I believe I can do most of it, except 1 part.
Right now if I did Ctrl + PageUp, it will send the key press to both apps. How do I prevent a keypress from the originating application?
