Dim Values As Object() = {S, DI.Name, "Folder", Nothing, DI.Attributes}
how can i add values to the object above with a for loop?for example:
dim i as integer
for i= 1 to 10
and now add eache value of i to the object?
I'm having a problem with passing on values from my data grid view to a textbox located in another form.[code]
View 2 Repliesi have a form that will pass value to my web application(vb.net) using <object> tag, and what i need to do is to get those value from it on page load.
for example:
<object classid="clsid:F08DF954-8592-11D1-B16A-00C0F0283628" id="info">
<param name="txtField1" value="Someone's name" />
<param name="txtField2" value="some value" />
[Code]...
1. the number of parameter that will pass to my web application(vb.net) is dynamic
2. i need to know the param name and the value for that
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 have a dictionary of type:
Dim parentDictionary As Dictionary(int,Dictionary(string,string)).
Dim childDictionary As Dictionary(string,string).
parentDictionary.Add(1,childDictionary)
Now I need to iterate over childDictionary to fetch key value pairs.My childDictionary is inside parentDictionary.
I have a class called Item which contains all the information about all parts, finished goods, in process parts (parts made on site), purchased parts, and raw materials.
I have a Bill of Materials table which has the following columns (reflected in the BOM class)
ParentItem
ChildItem
ChildItemQty
Parent Items can only be Items which have subcomponents.
Child Items can be parts that are made on site, purchased parts that are bought ready made from other companies, or raw materials used to make a part that is made on site.
Parent Items and child Items both inherit the Items class.
I will limit the Parent item class to only items that are in the parent column of the BOM table. I believe I can limit that by doing a quick look up on a view which only shows the parent items.
I will limit the Child Item Class to only items that are in the child column of the BOM table. Same method to limit it by doing a quick look up on a view that shows only the child items.
That way, an instance of the BOM class will have all the detail information about any of it's components available whenever I need them.

when calling a webmethod
[WebMethod]
public Profile synchronize(string MID, DeviceUploadData data)
The object DeviceUploadData has many properties, and a few of them are array's. My question is about the array specifically. It loses it's value once it's received on the webmethod end.This is the property inside DeviceUploadData

Public Property Data() As DataObject()

So the DataObject is populated with data, then once passed, on the other end, some of the DataObject properties are no longer populated. I haven't included the other properties in this example.
This code works, as is, on my system. Problem lines are commented out. The last three commented lines are the problem.It creates the objects alright but a line that should send a message into the list box doesn't work. I am almost sure that the problem is in passing information into the sub routine. Forgive my use of ALL CAPS as it helps to see my comments on comments. A few comments in passing information to SRs would be helpful.
Also, how it is that I can comment out the .Name option and it still works?(I hope that this shows up properly. If it ends up as a big useless paragraph, I will repost it after learning how to do it properly.

my table looks like this.[code]...
I was able to do this via a SELECT CASE statement, however I'm always trying to improve my code writing and was wondering if there was a better approach. Here's the scenario:Each document has x custom fields on it.There's y number of documentsHowever there's only 21 distinct custom fields, but they can obviously have n different combinations of them depending on the form.So here's what I did, I created an object called CustomFields like so:
Private Class CustomFields

I'm trying to create an export Excel/CSV function that will iterate through a custom object and first output the property names and then output the values. I want to use reflection only where necessary so I'm attempting to save the property names when I output the headers and then reuse them to print the values. Is this possible? I'm a little weary of using reflection in a loop but is there a better way?

I accept both C# and VB.NET suggestion, even though I'm writing an app in VB.NET I have two lists of intergers
List1 {1,2,3,5}

I have a VB.NET project where I am able to iterate through the keys and values collections of a dictionary object using an index:
MyDictionary.Keys(idx)
MyDictionary.Values(idx)
When this code is taken from the test project and placed into the real project I get the following error:
'System.Collections.Generic.Dictionary(Of Double, String).KeyCollection' cannot be indexed because it has no default property.[code]...
In the line in sub search that says "dtf.Keys(idx) = 0" place your cursor after the right parenthesis and backspace you should get a tooltip that says, "<Extension> ElementAtOrDefault(index as Integer) as Double - index: the zero based element of the index to retrieve.
I've now properly started implementing OO into my system (which I probably should have done from the start) but I just want to clear some best practices.So let's say I have a class called Job which contains information such as Description, Project Manager (Employee class), Value etc. at the moment, if I initialise the Job class it will initialise all the information held within it, even if I only want the job description. Is it best practice to do this or is it better to implement the class and access the database for values as and when they're needed? Or is it just better in those cases to just access the database directly?

I am somewhat new to object oriented programming and am attempting to flatten a Linq object hierarchy by using a shim class.how to initalize a derived class with property values from a base class?I have two objects, a base object with about 100 properties, and a derived object which inherits from the base object and adds a few additional properties beyond those of the base object. My simple constructor creates the derived object, but I am looking for a way to initialize the derived object properties with values from the base object.Right now I am using reflection to iterate over the properties individually and I suspect there may be a better way. The following example shows my shim class constructor for the derived class, and two properties:
newProperty1 - a new string property of the derived class
flattenedProperty2 - a new string property of the derived class, copied from a 2nd-level object of the base class
Code example:
Public Class derivedObj
Inherits baseObj
Private _newProperty1 As String[code].......
Is this the correct constructor approach to flatten the object hierarchy using a shim class? My second question relates to initialization of properties in the derived class. The constructor above creates the derived object, but what is the best way to initialize the derived object properties with values from the base object? The following code uses reflection to iterate over the properties individually, but I suspect there may be a better way.
Code example:
' property names are in the string array fieldNames
'baseObjQuery is an ienumerable of baseObj
'derivedObjList is a list of derivedObj[code].....
Is there a simple way to initialize values for the properties in the derived object based upon the values of the common properties in the base object?
bare with me during this silly example. :-) Let's say I have a class like this:
Public Class Animal
Public iLegs as int32 ' Number of legs
Public bWings as Boolean ' Wings? Yes/No
End Class
And another class that inherits the "Animal" class and adds one more property:
Public Class ScaryAnimal
Inherits Animal
Public iScariness as int32 ' 0-100, how scary is it?
End Class
Now, if I have an instance of "Animal" with some values in it, and I decide I want to cast it to a ScaryAnimal for some reason, how do I do that without having to create a new instance of "ScaryAnimal" and copy each property value?Basically I'm looking for a way to do this, without having to write the lines marked with '*** below:

lets say I have a form (form1) with lables a-z which are all designed with default text "0". So they all show 0 on program startup. which is fine. I also have a dialog with 2 TextBoxes; I want my program to update the default text/value on (only)form1 labels x, y and z to whatever was put into the textboxes when i press the OK button on the Dialog, so these specified labels show the 'new' value on next startup. Is it even possible or should I save the values to a file which loads the values in the specified labels on startup?
