Updated date Dec 14, 2008 198k 0 4 A simple tutorial to add an autonumber column in a DataGridView.

Then add a Data Column, AutoNumberColumn with auto incrementing behaviour.

The Merge method will add the rows of the source table to the destimation table one by one.

Consequently, autonumber column values are generated as sequential row numbers Implementation In a few minutes, we will create a Windows Forms Application to test the case.

Run the program. See what happens private string ConnectionString get SqlConnectionStringBuilder ConnectionBuilder new SqlConnectionStringBuilder (); ConnectionBuilder.DataSource myDataSource; ConnectionBuilder.InitialCatalog myDatabase; ConnectionBuilder.UserID myUserID; ConnectionBuilder.Password myPassword; return ConnectionBuilder.ToString(); SqlConnectionStringBuilder provides a simple way to create and manage the contents of connection strings.

I can generate INDDMMYY using following code: lblNoSiri.Text IN Date.Now.ToString(ddMMyy) However, I dont know how to generate the last six digit number.

I even tried to retrieve it using a button event, but that also does not work.

I know there is data in the buffer.Heres my Private Sub DataReceived( ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs)code.

This device is very similar to the price portable price checkers you see in grocery stores.

More information about my device and about the big project im working on can be found here: My Idea For A New Type Of WCP (Wireless Connection Protocol) Code.

I wont use it that way im planning to do it on the startup of my program only blur the window not the screen (i mean the content of my window) untill you login or register then it clears again.

How to take a screenshot of my program (only yhe content of the window) Progress: 1 (cause i know how to take a screenshot of the desktop) 2.

How to blur that image Progress: 100 No need for third party programs or dlls i mean isnt there a default function in vb.net the stupiest way to do it.

Using the documentation provided by MSDN and the Forums I have managed to get data related to the Win32 Class (Computer Name, Physical Memory, IP Address, etc.) Now I would like to get the Serial number of the monitor.

However, I do not know the Syntax to access the property of the same.

I breaked point the debuging and I found that the serial number column I added is fine and has its values, but when I reach the line relations.add(therelation) the serial number column loses its values and turn into an empty column with no numbers in it.why this is happening Note: I added another relations but the only relations that clear the serial number column are the relations that has a datatable that is a datasource to the datagridview that has the serial number column.

I need to figure out an algorithm to produce a unique activation key for each serial number.

In Datagridview Vb Net Getsetting Trial Serial Number

I want to be able to store the trial serial number so if the user uninstalls and reinstalls they wont 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.

I tried in the Class WIN32PNPEntity, WIN32DESKTOP, WIN32DESKTOPMONITOR But I am unable to fetch the Monitor Serial Number.
