I want to connect oracle 9i database with vb.net. Can anyone help me in doing this?
Thank you.

Use OleDbConnection
Example connectionString:
"Provider=msdaora; Data Source=MyOracleDB; User Id=myUsername; Password=myPassword;"
Very simple example:
Public Sub InsertRow()
Dim myConnection As New OleDbConnection(myConnectionString)
Dim myInsertQuery As String = "INSERT INTO Customers (CustomerID) Values('1')"
Dim myCommand As New OleDbCommand(myInsertQuery)
myCommand.Connection = myConnection
myConnection.Open()
myCommand.ExecuteNonQuery()
myCommand.Connection.Close()
End Sub

I have a gridview in a VB2005 project that contains a checkbox. In VB2003 I used a datagrid and I have the code to read the datagrid to determine how many and which boxes were checked. I am having trouble converting my code to use a gridview. How do you in VB2005 read a gridview and determine if the checkbox was checked?
Thanks

There are many ways to do this. Probably the easiest way would be to add a DataGridViewCheckBoxColumn to your GridView. Then set the FalseValue property and the TrueValue property of this column. Then set the DataPropertyName property to the field you want to bind this control to from your DataTable/DataSet or whatever you are binding to the DataGrid. Now when the box is checked that field in the DataTable/DataSet will be set to whatever value you set as the TrueValue property.
I hope this at least will put you on the right track. Good luck.

Sir/Madam
I am Final Year Engineering student. I want to get information about connection of computers at different cites.
Actually if I want to computerize a department of any company which have its offices at several cities then what steps I should follow.
Means how I can connect that no of computers in appropriate manner to get desired output.
I want to make it just like railway reservation system through in which if I enter data at same time then database must be able to prioritize data in sequence to enter in database.
Which database & platform or language I should use to code this kind of project.
Thank You

Please don't cross post. Currently, you have posted this same topic on the Suggestions, Visual Studio, Work and Training Issues, General Discussions, Web Development, SQL / ADO / ADO.NET, ASP.NET, VB.NET, Visual Studio and C# forums. I see from your profile that you have been warned of this before.
the last thing I want to see is some pasty-faced geek with skin so pale that it's almost translucent trying to bump parts with a partner - John Simmons / outlaw programmer
Deja View - the feeling that you've seen this post before.

You're a final year student and you don't know what languages to use ? Do you know any ? There's no language I can think of that can't do this. The real question is, what language do you know ?
I'd imagine a central server which exposes a webservice and keeps the database.
Please don't cross post in future.

Hi,
Is it possible to read all the lines in a text file into seperate textboxes in vb6. If anyone knows please help.Thanks
|
|
|
|
|
the answer is yes. the consideration is that depending on the size of the file, that could be a large number of textboxes which could lead to issues managing that on the window.

Private Enum eLED_TEST
eLEDTEST_PASS = 1
eLEDTEST_FAIL
End Enum
Dim byteBuffer(64) as Byte
bytBuffer(1) = eLED_TEST.eLEDTEST_FAIL
After Building it gives the following error:
"Option Strict On disallows implicit conversions from 'Commlink2.Form1.eLED_TEST' to 'Byte'"
Can anyone please tell me what should be done for this?

bytBuffer(1) = Convert.ToByte(ED_TEST.eLEDTEST_FAIL)

hello
when I hit the delete button in BindingNavigator1 the update method of tableadapter give me this error.
"Update requires a valid DeleteCommand when passed DataRow collection with deleted rows"
how can i delete my data that be deleted in my database(SQL 2005).
thanks for your help

It's telling you that it doesn't know how to delete the data in your database because you haven't supplied an SqlCommand to do the delete. How are you setting up your DataAdapter to get the data?

I drag my object(textbox from dataset) form myconnection and VB.Net add the bindingnavigator,tableadapter,bindingsource.
i didn't use it it use automatically.
how can i supplied an SqlCommand delete my data from database
thanks for your answer and help

Does your database table have a primary key? If not, there's no way for the Delete command to uniquely find each record to delete it.
Also, I find supporting the Designed generated code to be a huge problem. Writing the code yourself gives you a much greater control over the data process and makes it much easier to support since you can actually find the code.

theatre booking with minimum 200 text boxes on form and maximum 600 text boxes, as seats looking for code for this to say whether the seats are booked or free as with multi dimensional array the code that is generated for each txt box would be phenomanal looking for easy way than that at present using tab index to code the programme.

Why not just use a multi-dimensional array? Also try looping through all the controls of the type textbox in your form.

would generate mass amount of code for just 1 text box.

I don't think you need to put any code in any event of the text box. like evilnoodle said, use the control collection
you didn't specify what you wanted done when you found a free seat so the below just finds the first free textbox...
For each oCtrl as me.controls
if typeof (octrl) is textbox then
with ctype(octrl, textbox)
if .text = "free" then
.focus()
exit for
end if
end with
end if
next
