VB6 Code
sdate = DateToString(dtpicker1 - 1)

It is showing Error.

I have a problem reading data from an RFID-reader. I connect to the reader by tcp and wait for DataAvailable to be true, then reading the data until I got a end of data character. Then I just go back and waiting for a new DataAvailable. This is done in a own thread for the function.
There seems to be some kind of timeout, If I don't got any data in a couple of minutes, then it just sits there in the do/loop waiting for DataAvailable. I hold the card to the RFID reader, it beeps, but there is no data available. I don't get any exeptions, and the information says that the clientsocket is still connected. Are there anything more I can check?
If I put the card to the reader in a minute-interval it seems as this will never occur. So 2-3 minutes idle:ing seems to do this.
Here are my code to read data from the socket, I have taken away some irrelevant code:
Sub test(ByVal ip As String, ByVal port As Integer)
' this sub is meant to run forever

I have a Master Page with nested pages in ASP.NET. Fairly simply I want to databind some hyperlinks to a gridview for the master page. This however is throwing a null reference exception when I try to set the DataSource.
I tested the code on a separate page and it works as expected. When debugging I can see the Page_Load Sub hit twice, I don't know if this is the cause I have one nested page being loaded, this is a blank page at the moment

View 1 RepliesIt's been a long while since I've done any VB.Net coding and need to bind some data to a form. I have multiple tables that share some common primary/foreign keys and need to easily be able to update them.
For example, I have a table with an ObjectID, TypeID, AreaID, and several other fields. When doing my layout, I need the TypeID (found only in the main table) to be a distinct value in a comboBox, and in the ComboBox which contains the Area to be the Area Description (from the main table tied to the Area table via the Area ID).
I have the following overloaded functions I use to fill a combobox.The first function works the way I want it to except for the fact that I pass a combobox in. I wanted to create a simpler function, thus my second attempt.For some reason the line:tempCombobox.DataSource = tempTable does not bind the data table to the tempCombobox. What am I doing wrong?
