VS 2008 Locking An Application After A Limited Period?

Sep 13, 2009

I am writing an application that I want to give to a select number of customers.

What is the best solution to use so that after the trail period (1 month) the application will no longer work.

I was thinking that if they are interested in purchasing the software I will give them a license key or something, to unlock the application. However, I would like to make this unique to every computer.

I am have a very limited budget as I am working on my own. So is there any free 3rd party products that does this?

I was thinking of writing the date the application was installed in the system registry, and each time the application loads it will check if this date is over one month. However, the user could turn back the date on their computer.

Another, solution I was to have the application run some many times. For example, the user can only run 30 times. Then it will lock.

VS 2008 - IDE Bug - Make Certain Forms Automatically Close After A Timeout Period

Sep 14, 2010

I caused the VB.NET2008 IDE to do something extremely odd and unintentional with some code I was writing. As some of you know, I mostly write programs for industrial equipment. On one of our products, I needed to make certain forms automatically close after a timeout period. To do this, I began programming a usercontrol with a Timer on it (interval = 1000) and a ProgressBar. Timer.Enabled was set to the Enabled event so I could toggle it. When the control counted to it's timeout period, it would call Me.ParentForm.Close

So I build my project, and drop it on a form in the IDE and I see it begins counting! Huh... I had no idea timers were active in the IDE. I wonder what happens when it hit's it's trigger? I figure probably nothing since Me.ParentForm was actually the designer. When it triggered, the whole IDE crashes without save. I tried it twice now. Here's my

VS 2010 Number Of Days In Billing Period?

Jul 19, 2011

If a billing period always starts on say the 22nd of the month and ends on the 21st of the following month then all I'd have to really figure out is how many days are in the month the billing period started right? I hate working with Dates! This is what I've come up with using the idea above...Note, Dates are strings in the first column of a Listview in the format of, mm/dd/yyyy.

' get month from start of billing period (last item in LV) ' example of dates: 06/22/2011
Dim BillStartMonth = CInt(ListView1.Items(ListView1.Items.Count - 1).Text.Substring(0, 2))

VS 2010 :: Make An Application To Save Images [or Download Images] To Local Hard Disk

Aug 12, 2010

I was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?
