you create a new io.fileinfo object, give it the url you want
then you call the create method
try that

You probably have to supply the full DNS name, not just the machine name. Like this: someComputer.myCompany.com. This, of course, depends on your DNS, or Active Directory if you have it, structure.

I am developing an application in VB.NET on the .NET framework v2.0, that consists of 2 parts. The client part, which is installed on the Client pc and the server part which is installed on the server (obviously)
The client part consists of a form containing a menuStrip, ToolStrip and an Explorer bar, all of which have no options as they are added to each of the controls at run-time, from an XML configurarion file located on the server. The server install also includes all the DLL that contain the Business logic. The client app connects to the DLLs ,on the server, using late binding.
All is working well when running locally on my PC, but as soon as I but the server part of the app onto my testing server, the .NET Framework security kicks in and stops the app from loading the DLLs from the server.
I would be grateful for any assistance on how to resolve this problem.

It doesn't work because in the .NET Framework, code running from a non-local source (i.e.: Network) is not trusted. Read up on Code Access Security[^] to learn about how to control trusting foreign sources.

A little Google goes a long way[^]. There's plenty of examples out on the web. All you have to do is a little searching.

I am assuming everyone...well most everyone here knows what datagridview looks like. On the control to the very left, there is something like a column that has an arrow type symbol in it and whenever a row is selected, that symbol is at the beginning of the row. I think it's called something like a row selector or something. Anyway, I was wondering what it is and how to get rid of it if possible.

|
|
|
I think it is Rowheader and there is some properties in datagridview property .

Yep, that was it, thanks enmahdi

Have you included the Microsoft.Office.Interop.DLL into your deployment package?

Thank you for ur immediate response.
Is any other way to make this file available in the target machine other than include to deployment package?

Try copying the DLL to the target machine, then on the target machine run RegSvr32 to register the DLL
for example
RegSvr32 C:\MyProject\Microsoft.Office.InterOp.DLL
It may work, but creating a deployment package is proberbly your best bet.

Cast sender to a Button.
Dim btn As Button = DirectCast(sender, Button)

i have a database of lists of subjects...then in my module, i want to display all the subjects that i recorded in the listbox...
how can i do it? i already connect my dataset in the connection wizard but i can't display it in the listbox.
|
|
|
|

at the first time you should set your listbox datasourse it will be your table in your dataset
and then set displayMember it will be the column name of the table it will be shown to user
and then set valueMember it will be the column name that is not been shown to user .

Try like that.
OleDbConnection nwindConn = new OleDbConnection("Provider=MSDataShape;Data Provider=SQLOLEDB;" +<br />
"Data Source=localhost;Integrated Security=SSPI;Initial Catalog=northwind");<br />
<br />
OleDbCommand custCMD = new OleDbCommand("SELECT Name from STUDENT", nwindConn);<br />
nwindConn.Open();<br />
<br />
OleDbDataReader custReader = custCMD.ExecuteReader();<br />
<br />
<br />
while (custReader.Read())<br />
{<br />
<br />
Listbox1.AddItem(custReader.GetString(1) = CompanyName);<br />
<br />
<br />
}<br />
<br />
custReader.Close();<br />
nwindConn.Close();
do searching a lit bit. man.... there are a lot of examples about how to populate the data into listbox in web or our forum....
