I am wanting to limit my applications to be free for the first 15 uses. I am wondering about the best way to do this.Should I save the number of uses in the registry? Is this the best place? (Can't people just delete the registry setting and then have full use again?)
View 3 RepliesI have a datagridview with checkboxes in the first column and I want to do a loop on saving the serialnumber(s) when the users decides to check a number of checkboxes Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code]...
the problem with this code is that it only inserts the serial number of the LAST checked checkbox and the number of entries of it depends on the number of checked checkbox for example ... if I checked the rows with the serialnumber 123 and 55652341, first the row with the serial number 123 then second 55652341, only 55652341 appears in the database and it is entered twice(twice because two checkboxes are checked)

I am trying to release my program now and I have a quick (hopefully quick) question concerning serial numbers. I want to be able to store the trial serial number so if the user uninstalls and reinstalls they won't get another evaluation period free of charge. My concern is that some crafty person will simply move the database files in and out of those installs and keep going indefinately. Although I have some protections built into the database itself in case the program runs out, I just want one extra layer of protection. Is there a way to store the serial number in the registry when entered and check for that entry whenever the program is installed using Windows Installer 3.1?

View 2 RepliesI am using zipforge.net to archive files in a small backup program I am creating. Everything works fine however if I try to archive a large number of files the process of zipping them gets slower the further along in the job it gets.
Example: I have a directory that contains a little over 100,000 files in it. Each file is only about 200k of text. When I use the zipforge zip class it starts zip'ing very quickly but as it gets about 40% of the way through the directory it starts to slow down... at about 60% its working at a snails pace.
Memory usage for my solution also goes up proportionate to the archive file size as it grows. Currently it takes around 26hours to backup this directory which only contains 4 gigs worth of information.
If I use a program like winzip I can zip the folder in less than an hour. I am thinking there has to be a way to write to the end of the zip file without having to open it every time or without keeping it open. My backup software scans the specified folder and writes each file path and name into a text file. Then it reads the text file line by line and passes the path + file info to the zipforge addfile().
I need a form width a checkbox "Don't show this again" for my winform, but how can i make this so when my Form1 loads it checks the state of the checkbox using the getsettings option?

I'm trying to create an app to launch at start up that will ask you what applications you want launching, or if you want all your favorite app's to start up etc. But before I go any further, I think its crucial to know how to save settings that a user has entered (such as program location and name in this case) so that he/she doesn't have to enter them every time at start up.
So far I have just made this, can anyone tell me how I would get it to save the settings entered?

I have an application that I need to be able to read and save a bunch of registry settings before they are changed. The purpose of this is to revert any new changes back to the original configuration. My application checks the state of each of the registry keys on startup. Is there a way to have it save the current configuration and then reload that configuration later ?

View 1 RepliesI'm creating a program and i want it to secretly save when the user clicks on save.
In other words, i have made it so that it saves twice. Once for the user to read (like a fancy copy) and another that the program uses to open up the form.
Currently when pushed, 2 save dialog boxes come up after each other. I don't want this to happen. I want 1 to come up (the user friendly, fancy version) which is the easy part, but i also want the other 1 to save automatically and secretly without asking the user to set the destination.

The registry key exists on my PC, so I'm having a hard time debugging it on another PC. When it threw the error, I commented out the last block of code to see if I was checking the key wrong or if it would throw the error just on the variable declaration.
Which is did. I get why it did. You can't .Open a key that doesn't exist. However, I looked it up and everyone is recommending that we do it this way. But this way doesn't exist.
