Why? Why does every noobie think that the .NET Framework should be this be-all, end-all, embodiment that makes everything so much easier? What ever happened to writing code to do it yourself?
But, I digress...

It's not a good idea, because no application actually supports doing this, but it is possible to change the parent of a window to another window. You can get some strange things happening during painting, so don't say you weren't warned.
Private Declare Auto Function SetParent Lib "user32" ( _
ByVal hwndChild As IntPtr, _
ByVal hwndParent As IntPtr) _
As IntPtr
.
.
.
' Launch a new Notepad process, wait for it's window to be created
' then reset that window so it's parent is another window in our
' application. In this case, a Panel control.
Dim p As Process = Process.Start("Notepad.exe")
p.WaitForinputIdle()
SetParent(p.MainWindowHandle, Panel1.Handle)

hi,
r u talking about any dummy(sample)projects??
u can develop the sample applications like Student management system, Banking system, AddressBook, Personal Assistant,
Shopping cart,Webbased Address Book etc., if u r looking for sample applications,long back i saw one site where u can find the sample applications with source code. just check the urls for the sample applictions. but it's better to take the specification from that site and try to develop ur self by implementing ur own ideas.
u can find sample applications in microsoft site also.
check these links:

cmd.Parameters.Add("?addr", MySqlDbType.VarChar, 200, txtAddr.Text)
parm = cmd.Parameters.Add("?custname", MySqlDbType.VarChar, 15, txtCustName.Text)

When you need to perform an SQL statement that doesn't retrieve any data, you can use the ExecuteNonQuery method. So you will not need a DataAdapter object. You just use the command object. So you will need a line that looks like this:
cmd.ExecuteNonQuery()
The da.Fill(ds, "cust_mast") line that you have in your code is really only to be used for an sql select statement.
Hope this helps.

I'd write a function to either a) sum that values in the dataset that the grid view is bound to or b) query the database directly.

I still don't understand can u give me through example?

Hi,
I am using cross-tabs report for reporting in crystal reports for .net 2005. When the width of the report exceeds the width of the page so it cuts off the rest of pages.
|
|
|
|
|
Have you tried resizing or restructuring the layout? I think that would be the first step.
