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[^].

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

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.

Hi,
I have placed a list View control & a Tree List View (Custom control obtained from this site for placing the tree & list view together) one below the other for a specific requirement in my application. Now I need to synchronize the Horizontal scroll for both these controls.

Any idea on how to do this is most welcome.
