I'm looking for the best way to set up application registration.Currently, I'm looking at hardware, generating a registration number from a variant thereof, then manually (through a created key-gen app) generating a serial number that I'm sending the registrant.Then, every time the app is stated, it re-generates the registration number, looks for the serial number, then checks to make sure that they match.until The problem with this is it ties the serial to that machine. I'd like to allow for transferring to another machine.What are some other solutions for application registration that will ward off pirating. i don't want to make it too easy for someone to install a single copy on 5 machines, or worse, share the serial with friends. I'd like to get paid for my work (call me crazy). I know about the 80/20 rule (of 100 registrations, 80 will pay, 20 will pirate) or 70/30 or whatever you hear, and am not opposed to that, but, hey, closer to 96/4 would be nice, right?
i developed a very simple vb.net application and i need a way for every user to verify that they have paid for it. i would like the simplest method possible. it will be an off-line registration. I am actually looking for a way that I can program this easily myself, and am not interested in third part solutions.
I hv developed a vb2005 based win form application. I would like to include application registration module.The planned i/p fields are usr name, productID. Based on this two filelds a unique registration key will be produced.
what third party software is around that I can use in my VB web application to 'call home' to my website to get a registration key.I saw something that did this a while back but can't remember what it was called.

create an application that calculates the registration fees for a conference. The general conference registration fee is $895 per person. The is also an optional opening night dinner with a keynote address for $30 per person. additionally, the optional preconference workshops listed in table 7-16 are available. [code] When the user clicks the select conference options button, it should display the conference option form the conference options allows the user to select the regular conference registration, the optional opening night dinner, and an optional preconference workshop.(the user cannot register for the optional events, however, without selecting the conference registration of $895.) when the close button is clicked the conference form should be removed form the screen and the total should apper on the main form. [code]

I am writing an application that needs several random numbers. Each time I use the Rnd() function, do I need to precede it with the Randomize() initializer?Or can I just use Randomize() once at the beginning of the code?Examples: Do I need to do it this way?
I need to generate a lot of random 2 character strings for my application. it's a VB console application. basically what I have tried for random strings is this:
Private Function GenerateRandomString(ByVal intLenghtOfString As Integer) As String 'Create a new StrinBuilder that would hold the random string. Dim randomString As New StringBuilder
[Code]....
What is going on? I thought that I used to, a long time ago, be able to just do random.Next.
I must say I don't get the vb Random function. Try making a basic winapp application, but a button named Button1 and a few (around 10) labels on the form. Then add the following to the forms codebehind:
Code: Public Class Form1
Public Function RollDize(ByVal iDize As Integer) As Integer
Dim iRes As Integer
[CODE]...
Now, if you click the button, you will see that all the labels get the same number. However, if you step through the code in debug, the numbers are random.
I'm have a quite big application which have 2 serial ports and access 1 DB (running on Background workers). I'm experiencing some random locks while the application is running and I started looking for something that could cause it. One of the obvious possibilities would be if I had in the GUI thread some While_End that would never return.I have one While_End in my GUI thread but IMHO it does not look like it would lock, so I want your opinion: Does the code below looks like will lock?? If 'yes', Why ?
[code]...
Does anyone can imagine a scenario where this While_End would not return ?
making a VB application which chooses a random line for a file, sets it as the value of a Label (word) and also adds it to a ListBox (list) when a Button (nextbut) is pressed. I also want it to keep going.
Button; Text: Next Name: nextbut Label; Name: word Listbox;Name: list
What i need it to do is to load a line from a file ("C:words.txt" for example) and set it as the value f the label. The lines are different lenghts.
Iw ould like to know how to make it so every time you click on a button a different outcome can happen from the opens i gave the application.such as: when i click button 1.i will want it to either close the application or show a textbox but the outcome should be random out of the two.Like a dice if you get 1, 2, 3 the application will execute command "Me.close()" but if it rolls 4, 5, 6 it will execute the command "textbox1. show()"
I am trying to make a random shift scheduling application for a rotating workforce that must satisfy the following basic requirements: 3 shifts (8 hours each) per day (Morning, Afternoon, Night), 2 workers per shift work a maximum of 7 consecutive days and rest a minimum 1 day. 9 Total workers separate in 5 supervisors and 4 operators, and 2 part time workers (1 supervisor and 1 operator) for covering the possible absences of 9 standard workers. Total days off are 8 days per month (normal sequence 2,2,4) and the vacation days are 22 per year. A basic rule is that the shift must cover from 2 supervisors, or 1 supervisor and 1 operator. 2 operators are forbidden.
the error code points to a Stack-Overflow I can not pin the offending code down because the software works faultlessly on some computers after deployment but on others the crash occurs when a Gantt chart gets redrawn after changing activity dates. All the computers are situated on the same LAN and connect to the same SQL server 2008 database.The application has been developed with Visual Studio 2008.
I used the same install disk on all the computers and they are all using the same date/time format. The crashes occur on both 32 - and 64 bit machines.
The error message: Stopped working Problem signature: Problem Event Name: APPCRASH Application Name: Pfisterer Project Manager.exe
I'm trying to make an application where when the user clicks a button, it generates a series of 100 random numbers between 1 and 1000, and then saves those numbers in a text file. All I could come up with is generating ONE random number, but I can't figure out how to make it 100. Here is what I have:
I've read numerous posts and threads about random number generation, but I havent' run across this.If I generate a bunch of random numbers, the results are radically different if I create a new Random generator for each number than if I use on Random generator for all the numbers. The results are much more consistent and evenly distributed if I use the same Random generator.I would have thought the opposite,because creating a new Random generator each time should reduce the number of random repetitions, if a different time slice is used to create the random number.[code]......
The class Random is out right defective. It always produces the same random numbers in the same sequence. Things I have tried so far is every kind of seed you can think of as well as Randomize. The result is that I always get the same random numbers in exactly the same sequence.
I am practicing using the drawing commands, and have gotten a grass background and black happy face that moves around the background.It's a 10x10 grid of 50 pixels.I want (at the moment, when i press enter) it to generate a random number of trees (15 ~ 25) at random locations on the background. The program doesn't freak out about anything, and the variables seem to be right (using stop commands) but it's not drawing anything. Here is the code for the "GenerateTrees" command I have for when I press enter.
Private Sub GenerateTrees() NumberOfTrees = Int(Rnd() * 10) + 15 For i = 0 To NumberOfTrees - 1 bmap.MakeTransparent(Color.Fuchsia)
I would like to use integers generated by Random.org in a small desktop widow app. Im using visual basic. All My search terms bring up unrelated (to My issue) information. Currently I am using the local random statement/command.
I am trying to make a texas hold em game and it is of the utmost importance that my code generate a random number. But using a random number function that I always end up with a lot of the same numbers over and over again. Any ideas on how to make it "TRULY" random? [code]
I've made an image viewer which opens a random image from a specified folder, but the random number is not that random at all... I've already used Randomize(), but without result.
I just got Visual Basics 2008 Express Edition and I am very addicted to it.I am quite a fast learner. I was able to script together many fun applications that I learn from YouTube. I want to make a registration form look-a-like.I setup the design the way I wanted it and now its the coding part I am having trouble with.I have been on Youtube and this site for some tutorials but I still cant find what I am looking for. I have 4 Text boxes, one being Name, second being Last Name, third being E-mail, and fourth being Username.I also have a OK button that I want them to press when they fill in all text fields. The problem I am having is, say they only fill in the Name & E-mail field and leave the Last Name & Username feild blank when they hit OK I want a error to come up and say Please fill in all information. I have tried these codes and none seemed to work:[code]
I am making a program that allows users to share certain files, and it requires anaccount.How do I make a login system? I have my own website, so I have a MySQL thing...Could I link it with that? I have never really worked with account systems so I have no clue on how to add an SQL database and how to use it within the program
Although I thought I had registered for the 2008 VB Express, several attempts to run the application resulted in a "stall" at the following address: url...I tried uninstalling and reinstalling the application several times but with the same result.I also installed the latest Vista service pack. This is a problem with my desktop.I have not (yet) experienced the same issue with my laptop.
