You cannot create temporary volumes.

You can read up on Isolated Storage, with some how-to's, here[^].

That was not a cross post, it was a reference.

It's quite ok to make a reference to another post. A cross post would spread the answers in two threads, while a reference keeps the answers in one single thread.

I want to get the header of a stream, which has been recieved into a array of byte.
Is there a safe method to get the header quickly?

Here is the header format:

length 4 bytes,
ID 4 bytes,
SN 12 bytes

Thanks!

If I understand correctly and you're trying to convert from a byte array to primitive integer types, you can use System.BitConverter:

<br />
// data as a byte array<br />
byte[] data = { 0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a }; // etc. etc.<br />
<br />
// convert the first 4 bytes to an integer<br />
int length = BitConverter.ToInt32(data, 0);<br />
<br />
// convert the next 4 bytes to integer<br />
int id = BitConverter.ToInt32(data, 4);<br />
<br />
// what is SN?

You can use the ReadBytes(int) function from the BinaryReader-class

If it's a COM DLL, did you register it using regsvr32?

Did you create an install for the VB6 .DLL? It would appear that some dependencies are missing, like maybe the VB6 Runtime .DLL's, or some other .DLL that your .DLL is refering to.

It's a Setup and Deployment project. Look in Start/Programs/Microsoft Visual something... whatever, I haven't used VB6 in years.

You can get the runtime here[^].

DrawImageUnscaled......Scaled?

I draw an image in the form_Paint event handler:
e.Graphics.DrawImageUnscaled(bmp,0,0/*panel1.Bounds*/);
But the image IS scaled! The size of bmp is 2048*1900, but the whole image was drawn in a small area of the form, the width was 800 more or less.
Why scaled? How can I make it unscaled?

There's a problem with DPI.
Let use DrawImage(bmp, bmp.Width, bmp.Height): it's simper.

DataGrid's asp:ButtonColumn

Brendan Vogt16-Oct-05 21:25

16-Oct-05 21:25

Hi!!

I am using a datagrid to display my customer details, lik ethe first coloumn is the ID, then the next coloumn is the name, and the third coloumn only contains text that says Update. This column is a asp:ButtonColumn. If the user clicks on this link, it must take the user to the updateCustomer.aspx page and load all the customer details. I know that I can have a method for clicking on the link, but is a querystring the only way of going to the updateAgency.aspx page from the link with maybe the agency ID as a parameter? I would've liked to have the link work as a submit button and have no parameters passed like in the querystring, and maybe have it retrieved like Request.Form("ID"), etc. But how is this possbly, how will it know which ID to take as there are other customers listed as well.

Is there a way of clearing a datagrid?

Regards.
