Store An Image In A Structure?
Jul 26, 2009
I am trying to store an image in a structure, then display the image in a picture box by referring to the structure field. Right now I have declared the field in the structure as an Object, as in Dim objPicture As Object, then I am initializing it as objPicture = Image.FromFile(filename.jpg). When attempting to display it, I have coded picImage.Image = structure.objPicture. For anyone with knowledge on the subject, you know this won't work.

I have a .txt file i want to read that has states by abbreviation and states by name. In that text file some are territories and some are states.
I want to read from that file and put the abbreviations into one structure array and the states into another structure array.
I then want to lookup up the states by abbreviation or state name. The lookup will simply be selected by a radio button which will flag either the states full name array, or the abbreviation array.
all I have is the structures created:
Public Class Form1
Structure Lookup
Dim Abbreviation As String
[Code]....
How can I read from the .txt file and store into an array

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()
End Sub
