Create Custom Database In Windows Application - Double Click Custom Database File?
Jul 21, 2006
With VB.net, I'm coding a simple application to get more used to the new .Net format.
I'd like to save all the information to a 'new' database file. how to create a database on the fly, once that is done i'll be able to connect to it no problem, but actually creating the file is proving difficult to work/find out.
Also, with vb.net and the newly created custom file, how can it be made to automatically open that information with the program?
Is there a method in installation to associate the file type with the new program? How can i check when the program loads if a database file has been 'double-clicked' (rather than just running from the .exe of the program) and proceed to load the data?
EDIT1 - Extra InfoThe windows application has many different fields and content etc, then i need to save that to a file that could later be loaded by 'double clicking'. I assumed the easiest way would be to create a mini-database for each unique file
I've search the net in order to create a custom control but nothing I find is worth looking at, The main thing I want to do is create a skinengin via DLL and import it in my vb 2010 then using or creating some sort of skin builder where I can create a full setting file which contains all the details of the customization regarding the Form(Look, Feel and the controls such as a menu), I have used Iriskin and multiple apps doing this for me and when a user installs my application they still recieve a message about buying the registered DLL file, I would like to create it completely from scratch.
This is what I would like to achieve:To create a custom messagebox, with varying number of buttons with custom .Text descriptions, and other features. I intended to have a property array that would be redim-ed and have values (.Text values) set by the calling class:

I have created a custom logonui.exe in VB.NET and I know how to make it replace the existing logonui.exe, but I am having trouble with the functions, such as shutdown, restart and log in. I don't need to get the list of users, because there is only one user account on the system and it is not password protected. I just need it to log in to the account when the user clicks a button and to be able to shutdown when the user clicks a different button.
I'm Using Visual Studio 2005 and Mysql Database to create a windows application. The datagrid displays all the records. Since I don't know how to directly update from datagrid, thats why I have used textboxes for the respective datagrid fields. A load button is provided which on clicking puts the data on the respective textboxes. The data can be edited in the textbox. Problem is that I can't save this edited or modified data back into dattabase.
As i am trying to create a custom FTP server for an application i've been reading up on this for a while. One part of the problem is obviously the multi threading issue.Now i know that the synclock command will lock an object to the thread that requested it's lock, however in an example on the internet i found the following construction and i am wondering why he would do this.
Code:Private Sub ProcessClient( NewClient As Client )Call SendMessage( "530 Acces Denied", NewClient.ControlSocket) more codeEnd Sub Private Sub SendMessage(ByVal message As String, ByVal ToSocket as Socket)Dim CurrentThread As Thread = Thread.CurrentThread SyncLock CurrentThreadToSocket.Send(Message)End SyncLockEnd Sub Now ProcessClient is a thread that is trying to do some stuff with a newly connected client and SendMessage is just a sub in the same class as where the thread was created. Now normally one would synclock a "syncobject" however here he calls a sub and then from that sub he synclocks to the thread that called it. I wonder what the use of that is and why he does it this way?
I have removed the synclock statement and as I expected it functions exactle the same as it does with it. I tested it with multiple users at the same time trying to connect to it.

My Program is selected as the default program in the registry for any RTF file that is double-clicked. I want my program to load the RTF file when I double-click it in windows explorer, however, I also have my program set up so that it always opens the last file I had open, which is stored in an INI file. I do not know how to detect that a file have been double-clicked in Windows Explorer within my program as it loads (FormMain_Load), and then load that file instead of the last file open.

I would like to generate a tracking number as primary key for my database.
There will be total 12 letters for each tracking id. Example: 2012010001-1
The "2012010001-1" is actually from combination YYYYMMxxxx-v where YYYY is the current year, MM is the current month, xxxx is the auto generate number(increment) and -v is the version where it can be -2 -3 but using the same YYYYMMxxxx.
For both YYYYMM is not a prob as i can get the value from Date.Today.Month/Date.Today.Year. But how am I going to ensure the xxxx is an auto increment but will be reset back to 0000 every new month.
For example:
2012010000-1 (Month January, so start from 0000) 2012010001-1 2012010002-1

Is this even possible? [code]

I need two seperate lists, which every item is Integer, String, Bitmap - and one which every item is Integer, String String. However I don't know how to do this, or even where to look - I've googled for custom objects and custom object lists.

Any help, or even links to information that would be relevant to this request would be helpful?
