.net - Make A Product Key Registrar For The Program?
Oct 17, 2009
I am trying to make a product key registrar for my program. I want the product keys in a database or a dictionary type thing where I can make new keys everyday without putting them into the program, and redistrubate them everytime.
Right now i have a form in the VB where there are 2 combobox in it. user can choose from a range of products that comes together with some description and these are to be stored in a database table.. when i retrieve these data from another form in VB, i'm only able to retrieve the first product and it repeat e same product in my second textbox.
I have 2 datagrids. One to show Product information and another for Product purchase details entry. Both share the same dataset. The dataset (ds) is filled up with columns from 2 table
The problem is that: Showing from dataset or entering new records into the dataset is no problem, but am not able to save the modified dataset into DataBase. SqlCommandBuilder failed to generate the corresponding INSERT, UPDATE command as the dataset has multiple base tables.
I am wondering how to make a product key as a license key for my VB.Net windows form application? Because at the end of the day, i would have to package it as a exe file and i would like to include in a license key for the user.
And also may i know how to package the whole project as a exe file such that after the user excute the installer, everything will run. like how you install windows xp like that.
im trying to make something to protect my application a simple serial key the only thing i can think of is if textbox1.text = ("key") then blah blah blah you get it. what i really want is something that will allow me to add and remove keys without having to mod the application, something that would check a site like
I am looking for a free utility or way to protect my software by requiring a Product ID (Which will be created when a customer requests a paid license) to use the application after a demo version. Like most shareware apps.
I made this thread a discussion thread instead of a question thread because I would like hear opinions on how I should do this best. Right now, what I am wanting to do is done with macros inside of microsoft excel spreadsheet and I think a program that is easier to control and perform updates and that did the same thing might be simpler for the end-user and for me. The Excel sheet works fine for right now but editing the macros when a change needs to be made is a pain.
I would like to have a VB program where a user will scan in a serial number and a tester number and then that information will be stored in a sheet, like excel or pdf or something, and then when that sheet reaches the limit of parts that should be on a certain sheet, save the sheet to a specific folder and then print the sheet out.
I will do a step by step breakdown to make it a little more clear what I am trying to do.
Step 1: User determines what kind of part is being scanned (Type 1, Type 2, Type 3, Type 4)
Step 2: User scans the barcode on the part. That data is entered into a sheet as well as the date and time when the part was scanned.Step 3: User then scans a barcode telling the program what station the part come from (Station 1, Station 2, Station 3, Station 4). Then the sheet is saved and waits on another part to be scanned, going back to Step 2.
Step 4: When the sheet meets the maximum allowed parts per sheet, determined by what part is being scanned, the sheet is saved into a folder and the prints itself out.I'm not necessarily looking for code for this idea but more of a 'Well, I would do it like this.." type thing.
I am trying to make a form that you can enter a serial (to validate the product) this is my code :
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged Dim T1 As String = TextBox1.Text Dim T2 As String = TextBox2.Text Dim T3 As String = TextBox3.Text
[CODE]...
The problem is when i first open my application and i enter my code it goes red, but when i re-enter the code in textbox 1 it works fine, how can i make it work without re-typing?
I have database in MS Access and this is Embedded to my program in VB2010 this is a Product Database now I try to create a reminder about my product expiration date
I cannot find a way to make a program that I write make a shortcut in the start menu for all users.My final goal is to make an MSI and deploy it in group policy to all users on a computers OU. Is this possible?
Dim IncomingCommand As String = e.CommandLine.Item(0).ToString
If IncomingCommand.Substring(0, 2) = "-1" Then
form1.close()
End If
End If
I am trying to make the program close if the -1 string is sent with the program. See my installer allows for me to run certain programs before it actually installs, but it doesn't shut down copies of the program itself. So I have a next startup instance set to shut the program down if the -1 is received. But if the program is not running it starts up instead. This is not desired. form1.close doesn't work. e.cancel = true doesn't work, etc etc. What can I do to make the program not start during this instance.

I have a product table on datagridview and I would like to add checkbox to each product so that I can mass delete them instead of deleting them one by one.
The GUI below shows the same product I inputted. If I inputted the same product and a new Quantity inputted, it will add to the current Quantity inputted. Same goes to the Total Amount will change.
I am a DCOM/Standalone Client-Server programmer who is now moving to eCommerce. I am building my first complete website for my wifes company and I have a design question for you gurus out there.
I looked at alternatives for shopping cart/product display and none of them meet my needs (e.g. ProStores). I wish to know which type of database you would use to have Many Products - Multiple Images per Product - possibly Multiple Vendors per product. I have begun a RDB using access as a prototype and I feel there was no faster method than inserting every product manually. Is there an alternative? And would you use a frame to display this data?
Would you store the images to the DB or a file reference on the host. I have begun with a file reference and truncated the path to only relate to where the file will reside on the host.
