Way To Stop Other Person To Use Dll In Application?
Jul 2, 2010
We are developing an application in VB.NET 2008. We break the application into smaller multiple dlls so that we can easily update the program at the customer end.We want to know that is their any way to stop the other person to use my dll in their application?i.e we want to lock the dlls such a way that the dlls will be used by us only and not anybody in their application.Also we want to block viewing of dlls code using any code reflector

I have a Person class, which contains two public properties. I am trying to add items to it as follows.
Code:
Class frMain Dim persons As New List(Of Person()) Private Sub frmMain_Loaded(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded GetInfo()
[code]....
When I try to use the Object Initializer, I get an error Error"Value of type 'Person' cannot be converted to '1-dimensional array of Person'.
I'm trying to make a application that allows the person to script config files for an open game server project so they don't have to do it manually... I'm starting with 3 groups. Those groups are "NPC NAMES", "MONSTER NAMES", and "MONSTER WALK POSITIONS"... I want the user to be able to add as many items to the group as they want... Right now I'm using a listbox, but its very messy... I want the user to be able to add items to these groups, and then add the items of each group to a .txt file.
Create an application that allows the user to select or enter into a combo box the number of days a person will work, and calculates the total amount of pay she will receive over that period of time. Salary is one penny the first day, two pennies the second day, four pennies the third say, and continuing to double each day.
The combo box must list the following items: 30, 180, 365, and 1000. Must be the default drop down box. Use a validating event procedure on the combo box.
The program should go through a loop once for each day, doubling the number of pennies with each iteration of the loop. You will need a running totl of the number of pennies that you add to with each iteration. To calculate the total amount of pay, multiply the total number of pennies by .01 and show the result in currency format.
Public Class Form1
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
The fact is I'm making an application, which users can install by using a Setup file...once installed the data in the database can be updated by a centralized server. To do this, they can insert a DVD/CD-ROM and export the necessary data towards it. I need to do it that way, because some of the users who really need this data will be using stand alone computers.The application gets it's data from a mdb-file and the connection remains open as long a person works with the application (maybe not the best way to do, but I know :-) )...when the user uses the application, he can perform an export...this exports the .ini-file and pictures (which works fine), but he also needs to export the mdb behind the application...I already tried connection.close() before and connection.open() after the System.IO.File.Copy...but that doesn't seems to work.
I am trying to make an application with a start button and a stop button on a stop watch program. These are the codes I am using but my seconds on the stop watch don't start.
Public Form Dim intSecond As Integer = 0 Form 1 Private Dim intSecond As Integer = 0 intSecond +=1
[Code]...
After I write my code and try to run the program, the seconds will not start,
I have a windows forms application that has no form and it runs in the background. It using a webbrowser control to get information off the internet.The program is that when I add the event handler:webbrowser.documentcompleted the program just shuts down. If i put a message box after the event handler then it works just fine because the webrowser has time to load the document. How can I do some like console.readkey that you would do in a console application?
I have an application in wich I have included a timer wich close automatically the application when no activity is detected.My problem is that when I make 'some activity' like accesing something, I do not know how can I reset the timer to 0.
I have something to ask again.. I develop a program that will send bulk messages but the problem is that when I load at least 1000 emails then I want to stop the application I cannot stop it. Is there any way to stop this application without closing the form? So that i can save the file on my listview? Here is my code upon send bulk emails. [code]...
I have created a small program but the code is quite big.
I have a start button that when clicked it runs the script in a private sub called start(), when it gets the the ens it calls the start() again to loop it and restart the script.
I have added a stop button, but how do i make the script stop ?
I have an application in which there is a do...loop. I need the do...loop to perform some code and then stop for .1 of a second. When i try using System.Threading.Thread.sleep(), a wait cursot comes up and the application stops working. I was wondering if there was any way to get the thread to stop without stopping the application.
Guys anyone know how to stop or close a running program remotely through a vb.net program? am already aware on how to run or open one using the System.Diagnostics.Process.Start method. I would be needing it in my next projec
I believe I have found a solution! I will be continuing testing to make sure it DOES in fact work, but I'm hopeful :) I have detailed how I found the solution in EDIT THREE of the question.
For anyone wishing to know the full background behind my problem and what I have kind of tried as a result of input from this question, see this: [url]
I will be editing this frequently (>3 times a day most weekdays) as I progress my research and situation, so keep checking back if you are interested or have some information or knowledge of my issue :)
Quick Background:
I have this app I have made that can be crashed by changing my screen saver or locking my work station, and in general whenever a WM_WININICHANGE/WM_SETTINGSCHANGE message is sent to it.
If I can consistently crash my app by changing my screensaver, then SOME part of doing that is sending my app SOME kind of message (not necessarily a windows message, I mean message in the most general sense), which in turn is catastrophic to my application. Due to this, I am trying to find a way to block whatever message is causing my problem from being processed by my application. I am aware this isn't the best way to go about a solution, so you don't need to tell me. Look at the backgroung info or ask why if that bothers you (there is a good reason).
I have vb.net windows application. I want this app to be protected from being used remotly.Means some users on my network are using this app with remote desktop, some on internet use VNC viewr, team viewer or log me in to access this application.
I want to restrict this kind of access to my application. But I these users must be able to operate other functionality regularly. So can I write anything in my application so that i does not go over VNC viewer or team viewer or remote desktop
I wrote the following code to build a basic game that makes two cars race (randomgenerator) and let the user pick their bets on the end results. I've gone terribly wrong somewhere in that my cars only race halfway then get stuck behind the start line and the programme keeps repeating the beeping and the messsagebox.show and adding results to the 'incorrect' box.
The only way to terminate the application is to hit 'stop debugging'.
Option Explicit On Option Strict On Public Class MainForm
How can I stop my application quitting until a backgroundworker has finished? Its an updater, so basically I want the form to hide until the download is finished, and then exit.I've tried to make a setting to tell the app when it is still downloading, and on form closing check this variable, but it won't work. For some reason it still quits!The update window is in a separate form to the main form, so the user clicks 'Finish', the update form closes and the main form stays open.[code]
I have written a converting program, which converts binary files to ASCII files. (VB.net 2010). I need to have a functional "stop" button on the form and I was wondering if there was a simple command to make a program stop, exit all procedures, and wait for user input on the form.
It is not feasible to multithread this application, as it frequently interfaces with the form. Currently, I have a global boolean variable which becomes true if the stop button is pressed, and I have internal loops checking to see if the variable is true. However, I don't to waste CPU on checking a variable if it's not necessary.
launch a Modeless Dialog I am used in me.showintaskbar property to remove application from taskmanager.but it removes the form(application)it still refreshes.How to stop the form refresh.
We just spent 300 man-hours fixing a buggy application in the field. It all came down to calling Application.DoEvents (re-entrancy problem).This was not caught in design reviews, code reviews.The code was inserted two years ago with the first version; the application was always "flaky" but recent changes exposed the re-entrancy problems to a greater degree. This incident is the second time in our organization that Application.DoEvents caused failures and multi-man hours of debugging.It was discovered in this case by simply noticing the call,buried way down in a complex event handler for an asynchronous task.What do you suggest to prevent this issue from happening again:
Add checkin gates to source control?
Developer training?
Code Analysis rules (why is this not already a built-in rule?)
