Depends which database engine you are using, but I'd look at the native support built into most db's these days to provide this functionality without programming effort. (I'm talking about SQL Server, Oracle etc - not Access.)
You could use log shipping, transactional replication, or a number of other methods - all controlled by the db engine itself. You'll need to look at the db's doc to find out what sort it provides.

Hi, I was wondering if anyone out there might be able to help me with the removal of the selectedindexchanged event from a custom combobox? I have created a custom combobox control and have the keyevents calling a method that will reset the selectedIndex changed event to 0, and then to -1. I do this because visual studio 2003 seems to have problems setting the combobox index to -1. In that method, I need to shut down the index changed event so that the event is activated only once when the index is changed, but I do not know how exactly I can remove the handler/disable the event within a custom control that inherits from the combobox. Anyhelp would be greatly appreciated. Thank you and have a nice day.
Code: -not working
'delegate declaration?
Shadows Event SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
'Handling event
Protected Overrides Sub OnSelectedIndexChanged(ByVal e As System.EventArgs)
MyBase.OnSelectedIndexChanged(e)
End Sub
'Reset Index
Public Sub resetIndex()
RemoveHandler SelectedIndexChanged, AddressOf OnSelectedIndexChanged
Me.SelectedIndex = 0
AddHandler SelectedIndexChanged, AddressOf OnSelectedIndexChanged
Me.SelectedIndex = -1
End Sub

I'm done with my browser and things are working very nicely, thanks to a lot of advice from the people here. My next project is a chat system but I'm not sure which approach would be best to take. I want to making the main application, that will nest all these other projects of mine (Browser, chat, ect), as peer-to-peer as possible in order to avoid as much server usage. I know that it will be unavoidable in certain cases but it is my ultimate goal. I've seen many examples on this site on chat systems but I'm not quite sure as to which is best. Any suggestions as to which type of system/approach would be best for this chat project of mine?
Any thoughts would be greatly appreciated.
Thanx

Hi,
When I lookin under "My Project", Settings, the value for my db connection is as follows:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\dbSpringBook.mdb
Is this not correct for deployment, as the app should find where the .mdb file?
|
|
|
|
|
Ok
I don´t know what you mean by |DataDirectory|
but what you can try is:
Dim DatabasePath as string
DatabasePath=Application.StartupPath & "\dbSpringBook.mdb
"
Then
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & DatabasePath
Put the database in the same path of your executable file.
Hope it helps

Hi,
I have included the database file in the same path as my executeable, but when I run the Publish Wizard in visual studio, and then execute the setup wizard on another computer, it still cannot find the database file.
Any other suggestions?

|
|
|
Hello
Can you specify the error that the application is giving you?
|
|
|
|
|
Sure,
When I go to run the Published Install from another computer, I get the following error:
Could not find file 'C:\Documents and Settings\Rashar\Local Settings\Apps\2.0\Data\GHJ14R6W\Data\dbItems.mdb'
*********** Exception Tet *****************
System.Data.OleDb.OleDbException: Could not find File 'C:Documents and Settings\...dbItems.mdb
at System.Data.OleDb.OleDbConnectionInternal.ctor(OleDbConnectionString)
...
So if i hit continue on the error, the app will load up fine, but I do not see any data.
Under "My Project" in the Publish Tab, I have clicked on the Application Files button and ensured that my database is included in the publish.

Hi,
I actually figured it out. I removed the database from my project, then readded it, and then selected the option Yes to copy database to project.
Thanks for your help.

IIRC, the control will only work when it's on a form. You can't use it without one. There's nothing preventing you from putting it on a hidden form though...

Hi Dave,
You just beat me to it. lol Abu this is one of the very generous people that helped me with mine, I'd listen to him.

Hi Abu,
The problem I see is that you are not adding the AxWebBrowser control to anything first before trying to use it. As far as I know you have to add it to a form, TabPage, Panel or GroupdBox or something like that. You can't just tell it to appear and start using it, it must be put on something of that nature first in order to use it. But I could be wrong, I'm new at this although I just finished working with the AxWebBrowser control to do a Web Browser myself.
