Nov 10, 2009I would like to define an interface in the same manner as IDispose. By this I mean that when the interface is implemented it would add functional code.
For example when IDispose is implemented it adds a fully defined Dispose method rather than just an empty sub routine.

Defining Ranges For Excel In .NET?
Jun 21, 2010I am using Excel interop in my VB.NET program. My problem is that I can't seem to figure out how to write to Excel *and* define the Range using numbers.Alright, so I have objects being created depending on the file that the user opens. So there could be 100 objects or there could be none. Now each object has an array of values, and these arrays contain nearly 15000 elements. So here is what I want to do but I can't figure out how to escape using the LetterNumber:LetterNumber combination.
For every object I want a new column to be occupied and for every element in the objects array I want the row to be occupied. I figured the easiest way to do this was using a for loop but, again, I can't use numbers.
For columns = 0 to NumberOfObjects
For rows = 0 to NumberInArray
Cell(0,0).Value = myObjectsCollection(column).Array(rows)

Defining A Name For A Variable Range Size?
Feb 18, 2012I have to define a name for a varying-length column of cells. The name is used later to define the range for a Data Validation List. I just cannot figure out (and the Help Function isn't assisting) how to define the Name, say "DropOrdNum" using a variable as the address for the last cell in the range. It is easy to define a name for "O13:O2000" - no problem, but then I have a whole lot of blanks in my drop-down list. But how do I define a name for "O13:LastCell", by making "LastCell" the Range Variable (am I correct in this) for the address of the last cell in the active range and then defining the name "DropOrdNum" as being the range "O13" to either "O(the row number of the last cell)" or "LastCell", being the address of the last cell in the active range, which varies by the hour?

View 1 RepliesVS 2010 Defining A Property As A Dictionary?
Sep 29, 2011I am trying to create a property and declare it as a dictionary. This property will be updated and called upon throughout my project. I may be complicating the issue but here is what I have...
vb.net
Private Shared m_ItemName As Dictionary(Of Integer, String)
Public Shared Property ItemName(ByVal Tkey As Integer, Tvalue As String) As Dictionary(Of Integer, String)
Get
[code]....
What I wish to do with the dictionary is to keep a record of the amount of items selected, the Key will be the Integer in the dictionary and will be the ID of that item in a database while the String will be the name of the item matched to that ID in the database.The user will be allowed to enter up to no more than 10 items at a time (overkill but necessary for the unknown).I was originally going to use an array statically declared allowing up to 10 items (eg. Private Shared m_ItemName(,) As String = New String(9,9) {})

View 1 RepliesDefining Path To Executable For A Custom Control?
Jul 30, 2010I have created a custom control using VB.NET in Visual Studio 2008 that gives extensive mapping and tracking functionality to a search and rescue app. The problem I am having is that in a number of places I need to define the path to the main applications executable in order to find a number of directories the control needs to function properly. Everything works fine when I am using it in VS but when I try to embed the control in a form in a separate solution I get the following error:
Failed to create component
'MainControl'. The error message
follows:
[Cod]....
This seems to indicate that it is looking for the GISDataDefault directory in the Visual Studio program path but I have used Application.StartupPath to define this location throughout the control.
This error only occurs when attempting to embed the control in a form outside of the controls solution. The solution I have created to develop this control has two projects (one for the control and one for a test form to do the debuging)
DrawImage And Defining Color To Copy Instead Of Mask?
Feb 7, 2012I am using VB 2008 & drawimage function to copy image A to Image B. My problem is image A has many different colored patches on it and I only want to copy the ones that have a certain RGB value. I was going to set the masking color to the RGB value but remembered that defines the color to ignore - Im interested in the opposite.
I know I could loop through all the pixels and check its color, but its way slow and Im hoping theres something better?

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If count.Elapsed.Seconds = 1 Then

End If
