Hi,

You will need to code one of the DataGridView's events to do this depending on when you want to add the date. As an example you could code the RowValidated event to add the date. In this...

To specifically answer your question, the reason you are getting this error is due to fact that you are declaring the variable within the If statements and therefore the scope of this...

Hi,

You have got this error due to the fact that you have tried to read the XML file into the same DataSet in which you created the the XML Schema thereby effectively duplicating the schema within...

Hi Niya,

Ahhhh, I now see your point since I made a typo in my original post by saying "Do Loop" instead of "Do/Loop Until", so, valid point made.

However, that said, as a human programmer you...

Hi Niya,

Hi Niya,

Actually, I would disagree with you on that point but I will not hijack this thread to debate the point.

Hi,

The difference between a While/End While Loop and a Do/Loop Until Loop is that the code within a While Loop may never be executed since the Condition controlling the execution of the Loop is...

Hi,



No, what I have demonstrated here is creating a Private variable at the Class level that is populated when the Form loads. Once loaded, this collection of in-memory strings can then be...

Hi,

You can do this by creating an object of Type Rectangle which represents a region on your form. You can then use the IntersectsWith Method of the Bounds Property of the PictureBox to see if...

Hi,

From what I can see of your code you are definitely making things more difficult than they need to be.

The first thing to do is read your Zip file into memory so that you save time by NOT...

Hi,

You would test the Count property of the Items collection of the ListBox. i.e:-


If ListBox1.Items.Count = 0 Then
MsgBox("No Items In ListBox!")
End If

Hope that helps.

Hi,

I do not agree with dunfiddlin's post here since you were already on the right track with a DataSet. However, what you will need to do is to create two related tables within the DataSet where...

Hi,



The first thing to address is your comment above. You seem to have misunderstood the fact that ALL variables that are declared within the My.Settings collection are, by default,...

Hi,



The first thing for you to realise is that what you are describing is NOT a For Loop. You are basically describing "How many times is a button pressed". To actually do this you would...

Hi,

Can you please try and explain that one a little better and in a lot more detail, since I and many others on this Forum, know how to use and explain a For loop, but understanding your question...

I have not had a look at dday9's example in his/her signature but one way to easily do this is to use the TextFieldParser Class. Here is a quick example:-

The first thing to do if there is something that you do not understand is to read the Documentation for the method that you are using. MSDN has a wealth of information on every Method...

Hi,

To begin with you should be using the Random Class in .NET rather than the legacy Rnd function that was introduced with earlier versions of VB. Using this calss, here is a streamlined version...

Hi,

I deliberately left the population of the ListBox as you had already shown it in your first post. So, the first thing for you to understand and learn is "What is being returned from the LINQ...

Hi,



In each of your events, you would test for the state of the Checked property to see whether you need to display your message or not. i.e:-

Good to hear and you are welcome.

Hi,

Yes, you can simply assign the value to a variable. i.e:-


Dim myValue As Integer = CInt(myDataRow(0))

Hope that helps.

Hi,

You have not mentioned what is going wrong so I cannot specifically comment on your problem but the one thing I would say is to remember basic school maths. What does BODMAS mean?
