You don't know how SQL works ? It's pretty simple, and there are tons of examples on the web. At it's most basic level, select * from [tablename] will return all the data in a table, and select 8 from [tablename] where [column] = [value] ( with single quotes around strings ) will select a particular value.

OK, you're connecting to a text file ? What does that have to do with SQL ?

From a textfile ? Is that even possible ? Your textfile doesn't have any named columns, if some sort of reading of textfiles is possible, I doubt it's using SQL.

The same way you delete a folder, one at a time. YOu need to iterate over sub files and folders before you can delete a folder.

I think VB2005 has a zip library, any other version, you need an external library

if u have installed winzip on ur machine and if it allows u zip/unzip at command prompt then u can do it easily....
1) create a process by specifing executable path of winzip.exe...
2) specify other parameters i.e. files to zip/unzip with required switches...
3) run this process...
Thanks & Regards...

Hello everybody!
This may sound like a really stupid question, but let me tell you that i'm new to .Net, so please be patient with me!
I need to find out what is the equivalent of the .additem function from VB in .Net.
Thank you sooo much!

That depends, what does it do ? Is it a method on a control ? If so, the controls have Items collections, so it becomes Items.Add.

Hi guys this is probably a really stupid question, but is there a better way of testing if an object implements an interface then this:
Try
CType(f, ISomeInterface)
Return True
Catch ex As Exception
Return False
End Try
Pablo
while(1){DoTheDo();}

I believe VB has syntax for the 'is' keyword, in C# it's if f is ISomeInterface. Also, you can compare f.GetType() and typeof(ISomeInterface).

Thanks, it seems you are the one to give me the answers most of the time LOL. Glad to have you here
Pablo
while(1){DoTheDo();}
|
|
|
|
|
Actually that didn't quite work...but it did give me another idea that works:
If Not f.GetType.GetInterface("ISomeInterface") Is Nothing
thanks
Pablo
while(1){DoTheDo();}
|
|
|
|
|
The proper syntax for using the GetType method is:
if(f.GetType()==typeof(IOtherType))
return true
else
return false
Visual Basic should not be much different from this.

i have created a datagrid using the vb.net wizard for my customer form, where you can add delete and navigate through records.
i have been searching the internet to find a way i can search a record in the customer table by the given primary key which is idsCustomerId. I am a complete beginner. Does anyone have any sample code?
This is what is generated by the wizard that i can see.
Public Class frmCustomer
Private Sub TblCustomerBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TblCustomerBindingNavigatorSaveItem.Click
Me.Validate()
Me.TblCustomerBindingSource.EndEdit()
Me.TblCustomerTableAdapter.Update(Me.CottageBookingSystemDataSet.tblCustomer)
End Sub
Private Sub frmCustomer_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'CottageBookingSystemDataSet.tblBooking' table. You can move, or remove it, as needed.
Me.TblBookingTableAdapter.Fill(Me.CottageBookingSystemDataSet.tblBooking)
'TODO: This line of code loads data into the 'CottageBookingSystemDataSet.tblCustomer' table. You can move, or remove it, as needed.
Me.TblCustomerTableAdapter.Fill(Me.CottageBookingSystemDataSet.tblCustomer)
End Sub
Private Sub ToolStripButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ToolStripButton1.Click
End Sub
Private Sub ComboBox1_SelectedValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedValueChanged
Me.TblCustomerBindingSource.Position = Me.ComboBox1.SelectedIndex
End Sub
End Class

Hi all,
I have a Movie Player Pro ActiveX Control attached in my project. I am able to play all different types of files on it apart from the one I want to play.
The file I wish to play is an .avi file (all other .avi files work).
The file i want to play was filmed on a DV camera, edited in Windows movie maker, then i saved it as a .wmv file (by default), which I converted to a .avi file.
I cant seem to understand why this doesn't work on my program?
What happens is I load the file, press play and I can hear the sound, but cannot see anything. It's just a blank screen.
I would appreciate any help on this matter.
Thanks in advance
Jaidev
