What do you mean by 'template' ? You can't hijack a browser on another computer via a windows program, no.

Have a look at the BitVector32[^] structure. It is specifically designed to assist with bit manipulation operations.

Well, a gridview can be set up to support an 'add' link that gives you a row with textboxes and saves the data to the server.

Meenge,

What Michael has been saying is:

Dim udtCustom() As CUSTOM_EXPORT '<< executing this lines does not actually create any instances of the array. You must specify a size by putting a number between the (). When you do that, now you can use that instance.

Dim udtCustom(1) As CUSTOM_EXPORT '<< now 0 and 1 (because the array is zero based) instances are available for accessing.

---------
Your other problem is the arrays within you structure. Creating instances of your structure does not create any instances of the arrays within. If you notice, in your original post, the () are empty. So once again the variable is created but equal to nothing or has a length of zero (depending on the type of object). So you have to create the instances for those arrays as well by specifying a size. You can do that either at the point of DIMming your variables or using Redim to allocate after DIMming. Michael has chosen to call a routine within the structure to set those sizes. You can either hardcode the size within the () or call a routine or set them outside the structure ex: ReDim udtCustom(1).List(5)

Hope this helps...

You can use some XML reader or DataSet.ReadXml().

I'm using the AppActivate function to bring an application to focus. This function works if the application has not been minimised. If it is minimised, AppActivate function won't bring the specified application to focus.

Hello
I want to make a chat program used to talk between 2 computers connected by LAN.
But I couldn't, I made a good one in VB6 using WinSock.
But in VB.NET, it isn't the same.
So can anybody give me a sample, or at least tell how to do it?

Thanks
