I am new to vb.net and I am designing a custom control and I want to have one of the properties of that control have a dropdown list where the data in this list comes from a database and is not hard coded using a Public enum statement..
I know that you can create a dropdown list using a Public enum statement where the list is based on the the data typed in the enum statement as seen in my project below. What I can not figure out is how to create a dropdown list of values that would be loaded dynamically from a query from a database, or from an array
Is there a way to to fill a enum statement dynamically based of data from a query of a database? Or is there another method for filling a drop down list of a control property? Please show me the code in VB and not C#
Public Class UserControl1
Private myDirection As compas_dir
Public Enum compas_dir
North = 0
South = 1
East = 2
West = 3
End Enum
Public enumType As Type
Public returnValue As String
Public Property CurrentDirection() As compas_dir
Get
Return myDirection
End Get
Set(ByVal value As compas_dir)
myDirection = value
Label1.Text = [Enum].GetName(GetType(compas_dir), value)
End Set
End Property
End Class

I need to import excel records into access database using vb.net 2003.i’m successful in retrieving records from excel to datagrid.
The datagrid may have 1000 records with 10 columns.I need to iterate through each row of datagrid to find whether this record is
already exist in access database 2003.i have given 3 field combination as primary key in database.if record already exists in
Database it should ignore that row and check for next record of datagrid.and if tht record not found in database then it should able to insert that new record to access database.i need ur valuable suggestion regarding how to proceed
Or any sample codes wil help me a lot.
Please give me the solution as early as possible...
Thanking you in advance.

You asked essentially the same question a month ago.
This isn't really a VB.NET question; it is more of a SQL question.
But, here is some help anyone.
Rather than checking to see if the record exists before inserting it, allow the insert to check if the record exists.
And, use a stored procedure instead of writing the SQL statments in the code.
Given these helps, you should be able to accomplish the task.

you said you have primary key table in the database.
So don't loop through each table rows with your records because it would take a lot of time
to loop through and execute the insert statement.
Better fire all the insert statements and catch the error message for primary key voilation and that's all. Your all the records that are not in the database will be saved and the other duplicate records will throw the exception saying it can't have duplicate primary key values.
enjoy

Not that I am aware of. You might need to look at third party controls or implement one of your own.

I have a spreadsheet showing a Purchase Order.
I wish to email it to the Supplier in a PDF format.
'Email The Order
ActiveWorkbook.ExportAsFixedFormat Type:=xlTypePDF, FileName:= _
"C:\DOCUME~1\David\LOCALS~1\Temp\" & strName & ".pdf", Quality:= _
xlQualityStandard, IncludeDocProperties:=False, IgnorePrintAreas:=False, _
OpenAfterPublish:=False
Application.Dialogs(xlDialogSendMail).Show
This seems to be the right way of doing it as far as I can tell.
HOWEVER...
It sends in .xlms format and can be opened at receivers end as spreadsheet!
If I send it manually as PDF no probs.
Where am I going wrong?

I've never used this call before, but, I ran a quick check in VBA.
It looks like Excel is going to e-mail the spreadsheet in a spreadsheet format, not the file is was saved as.
Having said that.... my advice is: save the file as a PDF, then send the PDF using other VBA code.
A search of how to e-mail in VBA should reveal results, if not, let me know.

That works.
It is a bit of a kludge, save file as PDF, send the PDF, erase the PDF file!
(Not elegant either, but as it works I shall leave it working now. Thanks for that!)

looking for an alternative and efficient way to transfer table records from one database to another database.
could it be done with one sql?

If the databases are in the same server, and the database user account has access to both, you can easily copy data from one database to another:
insert into database2..someTable (oneField, anotherField)
select oneField, anotherField
from database1..SomeTable
Despite everything, the person most likely to be fooling you next is yourself.

ty for the prompt help
but could i ask for code sample?
insert into C:\database2...
select *
from c:\database1...

The subject has asked it all.. but additionally, just wanna know how to simply use that component in windows app. Secondly how to add that component to toobox.
|
|
|
|
|
|
IIRC the latest release of code on CodePlex[^] is in VB2008.
Anyway - if you add the compiled dll to the references of a windows forms project the component should show up in the toolbox. If it doesn't try a "Rebuild All"...?

Any particular reason why you can't just loop through the collection of multiple items and insert them one at a time?

If you are qualified to write the application then surely you can write code to loop through the selected items in a list box.
