I want to implement a password text box that will behave like the one we see in Windows 7 (ie, when there is no user input, then it will display a string 'Enter password', and when the user press any key, this string is cleared). I tried all the events like 'TextChanged', KeyPress', etc., but failed to get the result.

I have a small VB .Net application that, among other things, attempts to substitute system wide typed text by the user(hotstrings concept). To achieve that, I have deployed 'ahk2exe' and 'AutoHotkeySC.bin' with my application and did the following:When a user assignes a new 'hotstring':
Kill 'hotstring' exe script file if running Append new hotstring to the script file (if non exist then create a new one)Convert edited/new script file to exe (using ahk2exe)Run the newly converted script exe(somewhere there I also check if the hotstring has been already assigned)However, I am not totally satisfied with this method for the following two main reasons:
The extra resources deployed with the application. Lag: The time it takes for the system to kill the process and then restart it takes a minimum of 5 seconds on my fast computer and more on other computers. That amount of time is much more than the time it takes the user to assign the hotstring, minimize/close the window and then test his/her new hotstring. When the user does so initially with no success they will think the process failed. So this method is not very good for user experience.I am looking for a different method or implementation. May be using keyboard hooks? Or maybe adding a .dll library that achieves the same. Are there any resources you know about that might help (free or commercial)? What is the best way to achieve my desired goal?

View 14 RepliesI am trying to figure out a way to implement password protection on documents that a program I am working on creates. They should remain with the document regardless of where it is copied to or sent.Here is a rough sequence of events:
1. Application Opens (no document loaded).
2. User opens document with extension registered to application.(could also be # 1 if they clicked on the document directly)
3. Application Security checks document for security and prompts if necessary.
4. If prompted, user enters password.
5. Application checks password.
6. If passed, document opens, otherwise user is notified of failure.
i have made a program that needs a password to activate it but i would like it to look for a text file in the same directory called "password.text" as it will alow me to change the password.

I'm making a custom control suited for handling passwords. I have created a control that inherits from a text box and I have implemented a lot of things so far. But what i want to do now is create a system so that when a user types It will display his last character typed for a X amount of time.Is there a way to turn only selected characters into password characters and still be able to get the password text from the Text property ?

is it possible to have my app protect a folder's files from being viewed by other users. like, if i set the command to protect a folder, then if anyone tries to access that folder will be prompted with a msgbox.
it probably means having a separate app loading at windows startup and constatly running in the background to make sure that folder isn't being accessed.
so much work to do and so many choices to choose from...
I am looking forward to reset password of Windows Seven by my app.Using command

But I don't know how to run this command
process.start("net user" & user_name & "*")
gives error.So how to do that or is there any other direct command which can change/reset windows password.
I'm working on an app that will only be used on Windows 7 and the user environment is very limited. Standard users cannot run exe files just by double clicking them. However, there is a bug that if you right click and click "Run as Administrator" on the exe, it runs without you needing to put the admin password in. So, what I'd like my app to do is sort of "emulate" this function on another exe. So the user clicks a button and it launches another exe by emulating the right click run as admin.Is this possible, without putting in the administrators username and password?
View 12 RepliesI am converting projects from C# to Visual Basic, and the namespaces in VB.NET behave in a weird way. There is some kind of hidden default namespace, and it's annoying. I want it to behave identical to C#, which works as expected - things go into the namespaces you create for them.
I've been getting around it usually with say
using MyClassLibrary;in C#, and in VB
Imports MyClassLibrary
Imports MyClassLibrary.MyClassLibrary
but it would be nice to have the functionality the same, and also logical.The other bigger problem is, I have a .tt file, and the C# project generates the code in a different namespace to the VB one.
Is there some solution to make both behave identically with regards to namespaces?

AccountsRemove Your Password").
The program should check:
1) Which User is currently logged on and using the program.
2) Check if the User has a password.
3) If No then Exit the program, else Step 4.
4) If YES then allow the User to type in his current password, press a button and Windows should remove the password.
I am using the follwoing code to generate Menustrip at runtime.
Dim dgv1 As DataGridView
dgv1 = Me.MenuDataGridView
ReadMenuInGridView(dgv1)
Dim MItems As New SortedList(Of String, ToolStripMenuItem)
For Each dgr As DataGridViewRow In dgv1.Rows
[Code] .....
Where the sub "ReadMenuInGridView" passes the DGV by reference and populates it with the menu item from the database. My question is,, the program as it is in the form listed above works fine (where I have a DGV "MenuDataGridView" created at design time), however, if I want to make it 100% dynamic and use a DGV created at run time I will not get the menu? Actually the program will not get in to the For loop?
Simply to do that we can replace the first 2 statement with:
Dim dgv1 As New DataGridView
'dgv1 = Me.MenuDataGridView

View 5 RepliesThis questions is for VBers, it's irrelevant in C#.
In VB, when you create a module, all it's fucntions and members are available in the scope without need to type the module name, just like all the VB functions (Rnd, Mid, IIf etc.).
I want to create a module but I should have to explicitly write it's name to access it's members, i.e. it shouldn't be loaded to the scope like a namespace.
Update
For example, I have a Module of extension methods, I don't want all it's members to show up on the scope and in the intellisense.
I want it to be available only by instance.ExtensionMethod().
If you create new projects in C# and VB.NET, then go directly in the Immediate Window and type this:
? 567 / 1000
C# will return 0, while VB.NET will return 0.567.To get the same result in C#, you need to type
? 567 / 1000.0
Why is there this difference? Why does C# require the explicit decimal point after 1000?
