Dynamically Pass Values To An Object?
Mar 28, 2011
How can I do this:
Dim oMyObject As New MyObject
oMyObject.DoSomething("Parameter1","Parameter2")
The "DoSomething" and the two parameters are dynamically provided from another script. They are stored in a string object in this script: sAction & sParameters. My question is how can I dynamically pass the "sAction" to the object oMyObject.For example oMyObject.sAction (where sAction should be the value stored in the sAction string). The example will probably not work. Is there a way to do this? The idea behind is to avoid having to write each function hardcoded, like:
If sAction = "DoSomething" then
oMyObject.DoSomething(sParameters)
ElseIf sAction = "AnotherThing" then

I am working on a application that has quite a few functions involved and have been thinking of the following: If I have a function that has a few paramaters, is it more efficient to pass the objects to the function(Example 1) or reference the objects in the parent(Example 2)? Does it matter if the objects are large or not?
Example:
Class mainform
Public myGenericList As New List(Of String)
Public myDatarowArray() As DataRow
[Code].....

I am trying to figure out how to do this or if it is even possible. I believe it should be, I have about 20 different tables with different amounts of columns in each table. I.E. One table might only have 4 columns while another might have 30 columns. What I am trying to do is create 1 sub/funtion that will handle the select and import for all 20 different tables, unfortunately for me I can't seem to figure out how to write this.
I know the select statement for getting the column names is :
SELECT column_name FROM INFORMATION_SCHEMA.Columns where TABLE_NAME = 'table'

I am trying to create a application scripting environment for my VB .Net application. I have a form type in the application called Project. What I want to do is dynamically compile (i.e Eval) VB .Net code on a Project form. This dynamic code always has a Main function. One of the arguments to Main is a reference to the calling Project form. Here is the Eval code:
Public Function Eval(ByVal vbCode As String, ByRef MyAssembly As System.Reflection.Assembly, ByRef ProjectForm As Project) As ArrayList
Dim Provider As VBCodeProvider = CodeDomProvider.CreateProvider("VisualBasic")

I am in the process of creating a program that needs to pass some information to another program. The program that needs to receive the data is meant as an update program to the first. I send a new copy of the host program over the sockets connection, then I need to pass the file name and location to the update program. After this information is sent the host program will quit so that the update can overwrite the host with the new version. The the update program restarts the host and everything goes on like normal. I have everything all-ready in place, except for passing the file information. I could just save the information in a text file and read form this, but it seems messy and illogical.

Greetings, I'm sure there's a simple solution to my question, but I haven't figured it out yet. I have a Form with 12 Label objects L1-L12. I'm trying to set the ".Text" values of those label objects with the values of the fields in a Database table,,, Here's what I have. It DOES NOT get errors. But it doesn't work either.

I have been updating a program that was made in VB5. It contains several lines of code that are drawing lines and arcs, for example:
Arc(picCameraImage.hdc, sngOldX - sngCircRadius, sngOldY - sngCircRadius, sngOldX + sngCircRadius, sngOldY + sngCircRadius, sngOldX, sngOldY, sngOldX, sngOldY)
I have figured out, or think to have figured out, that the new way of doing arcs and lines does not require the HDC, so that problem is solved. The problem I am having now is that with the new way, every example I have found created a sub that does the drawings, like:
Public Sub PictureBox1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles PictureBox1.Paint
Dim radius As Integer = 20
Dim diameter As Integer = radius * 2
[code]....
Is there anyway to pass values to this sub? I have to draw several arcs and lines and the values for them are different everytime. I would like to create a sub that would be used in every spot the old program used the old arc command and pass the needed values through it.

Is It possible to get the arguments' values used in the previous execution method?
For example:
Public Sub GetPreviousMethod()
Dim stackTrace As StackTrace = New StackTrace
Dim stackFrame As StackFrame = stackTrace.GetFrame(1)
'MethodBase: Get the previous method
Dim methodBase As MethodBase = stackFrame.GetMethod()
End Sub
If I use 'methodBase.Name', It works 100% and return the method name. I got the arguments' names of this methodBase using Reflection, and is It possible to get dynamically the values of the arguments?

I have various shape objects, and I want each unique shape to implement a saveToDB method that simply calls a DB object that implements a Save method with an object as its input paramter. This DB.Save method will be a long case function that implements the proper SQL commands based on the type of attributes possessed by the input parameter object.how do I implement the SaveToDB method in my Shape class? Is it something like this:
Function Shape.SaveToDB
DB.Save(Me)
End Function
The goal here is to let each shape save itself without it knowing anything about database operations; I want to isolate db-specific information in my intermediary DB object, so the DB object will have to figure out what type of object wants to be saved into the SQL database and then execute whatever SQL instructions are needed. And then if I override the SaveToDB method in each shape subclass, I can avoid the case statement entirely, replacing it with a series of unique methods such as db.SaveCircle (ob), db.SaveSquare (ob), etc., sincle the caller already knows what it is.

We have a few applications that will be passing a token object around and I wanted to get an idea about the best approach at doing this.
For starters, this token object is somewhat simple. It would have about 5 properties or so.
Would we create a WCF app and reference it through a datacontract?What about serializing it and sending it through an http post? (each app have a referenced dll of the object)Querystring? (I truly don't think this would be good, but put it up nonetheless)?

I'm writing a wrapper class to expose a subset of the functionality of a .NET FTP library edtftpne from Enterprise Distributed Technologies.
When you call the edtftp's GetFileInfos method you get an array of FTPFile objects returned. I'm able to iterate through these but I don't know how to pass them on as a new and different object array containing only Name and Size for each file. Here's the code I have. Sorry it's a little confusing because I have my own class named FTPFile and the .NET library I'm using also has a class named FTPFile. I'm using both of them here. I should probably change the name of my class just to avoid confusion:
Public Function GetFileList() As FTPFile() Implements IFTP.GetFileList
Dim ftpfiles() As EnterpriseDT.Net.Ftp.FTPFile
ftpfiles = fCon.GetFileInfos 'Fill object array
[Code]....
I'd just pass on the object array that I'm getting from the GetFileInfos method but COM clients won't have access to the class/object EnterpriseDT.Net.Ftp.FTPFile without me rewriting it, I'm assuming.
