The only way to run an application developed on Windows under Linux is to run it under a Windows emulator, such as Wine[^].

Hello There
My application is running in an environment where security policy does not allow the application to create folder on d drive. but my Application does have the Administrator UserName and Password. I want to create folder using Admin Credentials or you can say my application should run with Admin Rights no matter what ever the rights are for the logged on user.
Any helpful code or any Arcticle link would be highly appreciated.
Regards

Hello,
I have a datagridview that is bound to a bindingsource.
I have the binding source filter to only display 'ordered' rows. However, I have a combo box in the datagridview that will list 'ordered', 'to be ordered' and 'delivered'.
However, as the datagridview is filter to only display 'ordered' rows, as soon as the user selects either 'to be ordered' or 'delivered' it will automatically filter those rows. However, the customer wants to change all the displayed rows to 'delivered' then click save so all the rows will filter at that time.
Currently the row will disappear as soon as the combo box is selected to something.
I did try to use the suspendbinding, but that doesn't work for the dgv. I thought that might suspend the binding so the filter won't take place until after the user clicks the save button.
here is some code:
Many thanks for any help,
<br />
Try<br />
<br />
Me.bsOrderDetailsPending.Filter = String.Format("Status = '{0}' AND OrderID = '{1}'", "Ordered", Me.cboPendingOrders.SelectedValue)<br />
Me.dgvPendingOrders.AutoGenerateColumns = False<br />
Me.dgvPendingOrders.DataSource = Me.bsOrderDetailsPending<br />
Catch ex As Exception<br />
MsgBox(ex.Message)<br />
End Try<br />

I think you are going to have to rethink how the program is going to work behind the scenes. You will need a new field that will store the status you want to change it to. So you will filter by the status it currently is...and then when they click save, you will change the current status to the new status.
Hope this helps.

Hello,
Thanks for the reply.
However, that is not really the solution I was looking for.
The only thing i have found out is to do this:
<br />
Me.bsOrderDetailsPending.RaiseListChangedEvents = False<br />
however, by doing this the datagridview doesn't work as well.
Thanks for any more suggestions,
Steve

hi i cant find the query builder in visual basic express edition could someone point me in the right direction 2 find it cheers
|
|
|
|

Query Builder doesn't show up as a seperate option. You will only get that option in a place where it is appropriate, usually in one of the dialogs, for say, creating a DataSet or TableAdapter.

Hi,
It seems that you are planning to build a switch menu, if this is the case:
This is a tricky way
In form 1 > Button (or whatever):
Dim f as New Form2
Me.Hide
f.ShowDialog
Me.Show
Hope this will help

How i can use Microsoft Forms 2.0 controls like combox in vb 6 i fill combobox with list. how i fill it in vb.net 2005
In VB6 Me.CboCust.List=MyCustArray
In VB.Net Me.CboCust.Set_List(? , ? , ?)
What is the syntax of Set_List()
|
|
|
|
|
Hi,
CboCust.Items.Add("...")
You could add object too:
Public Class Customers
Public FullName As STring
Public Overrides Function Tostring () As String
Return FullName
End Function
End Class
Dim oCust as New Customer
oCust.FullName = "Naji El Kotob"
CboCust.Items.Add(oCust)
for more details got to msnd2.microsoft.com and search for "ComboBox"
Good Lcuk

Retrieve it to where? Back to form1? Same process, but in reverse.
