Use Serial Numbers / 30 Day Trials And Updates?
Apr 29, 2011
I have recently built a personal project but I forgott to finish some menu items and the application is only half done, as you can imagine from a developers point of view this is quite disapointing.
I could have rectified this if I new how to build applications that could be updated whenever I make changes.
My question is this:- can anyone please give me a basic run down on how to make my applications able to accept updates when changes are made ALSO how do I build applications with a 30 day lisence FINALLY can I write my own serial numbers or does Visual Studio create them automatically.

I just found this amazing DLL that can extract the hardware ID (computer RAM, hard drive unique serial number, partition serial number, CPU unique serial number, etc) of a computer.
However, there is no documentation for VB users and it is written in Pascal and assembly language. Ya, sad
connect to this DLL?The documentation says that the DLL exports the following functions:

Something ive wondered about as long as ive had an interest in making apps is generating serial numbers for software projects.Im wondering how is this done by the pro's so that someone can put a key into an app and without being connected to the net it knows the key is valid by using an algorythm.Id like to make something like that for the sake of learning how. I realise more and more programs now "call home" at the point of entering a key or to "activate" as with MS office and windows etc, but id like to start at the old school way of doing it.Generating the alpha numeric keys and also checking them.

I made my program and now I just need to add in the serial and trial part of the application. I know the application must connect to the host and go to a txtfile. How would i do the trial and serial. Also If the serial is already activated I want the application to reject that Serial and Count how many times they entered in a wrong serial.

I have a stand alone VB.Net 2005 application that uses a serial port that generally stays open while the application runs on a Windows XP system. In trying to bullet-proof the UI, I ran into a problem when the USB to Serial Converter normally used to provide the serial port is disconnected while the serial port is open. In trying to handle the resulting error when accessing the port, I find I cannot close the port.
When trying to do so, the error message says something like "unable to close the port. You may not have sufficient permissions." Reconnecting the USB/Serial Converter does not reactivate the port.

Im trying to write a program that will do:
1.The average of the four numbers. This answer will be placed into a text box reserved for that value. This text box cannot be changed by the user.
2.The maximum and minimum values. These will be denoted by changing the color of the largest number green and the smallest number red.
3.The range of the numbers. The range is defined as the difference between the largest and smallest numbers. The range will be placed into its own text box, labeled as such. This text box cannot be changed by the user."
Im using visual studio 2008 and it has to be written in VB

So how would I use .next (random numbers) to randomly select something from a list of numbers but it can't repeat the number?I could do:
dim num as integer
dim r as new random
num = r.next(1,5)
if num = 1 then
elseif num = 2 then
etc.
That wouldn't work because it would repeat.If I donwload someone's game can I disect it in VS? :0 I tried going to open project, then I went to the folder and clicked open. It brought me inside of the folder so I tried to open the game but there is no form1 there. It says the games name then .exe in the explorer-like thing in the top right?Also, how would I have a value or something in a label and access it from a button.
Example:This is in a label.
Dim number as Integer
number = 0
Then in the button do
Label.number = 0
How would I do something like that? I want to use that a lot as I did in a different language.

I am making a program, where the user enters 6 numbers in 6 different text boxes, and it displays the larger of those 6 numbers. But I also want to make it where if the user enters a string value (like S for instance) in the text boxes, it gives an message and says "please enter the numbers again" and the user gets to enter the 6 numbers again. But when I do try to do that, it gives an error message saying conversion from "w/e the user entered" to Double is not valid. If the user just enters the numbers, it works fine. However, I am trying to make it if the user does enter non numeric value, it gives a message window and the user can reenter the numbers again.
Here is my code Example
CODE:
This is where I am trying to use IsNumeric to show a message if a user does not enter a string so the user can renter the numbers again, but when the user does enter a string value (say in textbox 1) it gives me an error message saying conversion from "S" to 'double' is not valid.
CODE:
Then right here this is where I have my series of ifs statements, this part works fine, it displays the largest numbers of the 6 textboxes every time. Error free.
CODE:
And do this with variable number 2, 3, 4, 5.
I know there are easier ways to do these with arrays and stuff. But I am not there yet. I am still learning about ifs and stuff.

I have just about completed a .NET project to write a program to randomly select numbers for a Bingo caller. Over the last month or so Ive learned a lot about .NET but heres something that I consider to be odd and maybe one of you guys can offer an opinion.
One of the features of calling Bingo in a small local club is that callers often use little sayings to accompany certain numbers, I expect youve all heard of (say) All the sixes, clickety click for 66 or 5 and 9 the Brighton line for 59 etc. My little program gives an option to incorporate these with a prompt for the caller that can be edited outside of the program. One of these conventional sayings is used when a number is reversed 12 followed by 21 or 45 followed by 54 for example, when the caller might call (say) 1 and 2, one dozen, number 12 And the other way round 2 and 1, twenty one.
So, I programmed in a bit of code to detect this and to over-ride whatever might otherwise have been the quote with And the other way round and set about testing it. Ive been through literally dozens of full 90 calls watching for the occurrence of a reversed number, spent a few hours doing it, and not once has it occurred which is to say the least, unusual.
So, Im wondering about the Rand Function, could it be that it isnt possible for a reversed number to be selected? Just so you know, I randomly pre-select the order of all 90 numbers, I fill each of the 90 elements of an array with a random number first checking that the number selected hasnt already been stored, if it has, I just get the next random number (and check that too of course), but I cant see how that could prevent reversed numbers being selected, especially in light of the fact that frequently it's not the 'next' number that's used.

I am currently working with a vb2010 front end with access as the database. everything works for accessing the information adding information. But when I try to edit/update the contents of a row I find that the update is being applied to the first row of the table rather than the target row. i have tried using the ID as a way to specify the row i want updated but that doesn't appear to work.

In the following code, TextBox5 reports conditions while the mouse is moving over the form, and TextBox7 reports only when the mouse has STOPPED moving over the form. When I start the program, and move the mouse from outside the form, onto the form and don't stop the mouse, the coords continually update in TextBox5 as expected. When I then stop the mouse, TextBox5 clears and TextBox7 reports, "Mouse Hovering", also as expected. Then if I start moving the mouse again, TextBox7 clears, and TextBox5 starts displaying mouse coords again, as expected.
