If Else Conditions Won't Work

May 10, 2009

Public Class Inventory_Edit
Private Sub Inventory_Edit_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'CategoryDataSet.Category' table. You can move, or remove it, as needed.
Me.CategoryTableAdapter.Fill(Me.CategoryDataSet.Category)

[URL]

I added an "edit" icon on my bindingNavigator. When users click on it, a new form will come out and pull out all the data records from the datagridview. Now the strange thing is that when I wanted to edit the data records, when I left the product name blank, I would get an error message saying "Product cannot be blank" - please see above code. But when I left the "Cost Price" blank(same applies to "Sell Price" and "Quantity"), the error message box wouldn't come out, instead, it did not allow me to move on to another textbox, close the form etc until I filled out that textbox with INTEGER. May I know why the error mesagebox would not come out when I entered the wrong datatype?

Using Operational Conditions?

Feb 1, 2011

I am very new to vb, I know there is an error somewhere, I had an assignment which stated that if a number was < 101 or > 500 and the answer is correct the output should be, for example-123, if the answer was wrong then the message output should be wrong number <101>500. Everytime I type in a number(no matter what the number) and click on my check button I get the output message. If at all possible, can you please assist. My professor gave the following example, but I am still not getting it:

Dim strInteger As String = "52.801"
Dim dblNumber As Double
dblNumber = CDbl(strInteger)

Asp.net - LinkedResource With Question Mark In Path?

Nov 24, 2011

I am trying to create an HTML email with an attached image using asp.net VB.

The trouble I am having is that the image is stored as binary code in a table rather than on the server.

I have the following code:

Dim myHeader As New LinkedResource(Server.MapPath("/Handler.aspx?id=237"), "image/jpeg")

I know it's the question mark in the path that's causing the problem. Does anyone know a way around this??

C# - Mark Non-unique Rows In A DataTable?

Dec 6, 2010

I have a DataTable which I want to check if values in three of the columns are unique. If not, the last column should be filled with the line number of the first appearance of the value-combination.

[Code]...

I solved this by iterating the DataTable with two nested for loops and comparing the values. While this works fine for a small amount of data, it gets pretty slow when the DataTable contains a lot of rows.My question is: What is the best/fastest solution for this problem, regarding that the amount of data can vary between let's say 100 and 20000 rows? Is there a way to do this using LINQ? (I'm not too familiar with it, but I want to learn!)

Evaluate 3 Conditions In An If Statement?

Dec 9, 2011

So I am trying to evaluate 3 conditions in an if statement. Its not working how I would assume it should. I basically want to do this:

vb.net
If PGN = &HEF007E And PGNData(0) = &H58 And (PGNData(1) And &H40) = &H40 Then IgnOn = True Else IgnOn = False

If I write it in that manner it gives inconsistent results. If I workaround by writing it this way it works perfectly:

vb.net
If PGN = &HEF007E And PGNData(0) = &H58 Then
If (PGNData(1) And &H40) = &H40 Then IgnOn = True Else IgnOn = False
Endif

What is the proper way to do this with only one if statement?

C# :: Conditional Logic For Gridview ItemTemplate (using Mark Up Only)?
