Application.Settings VB 2005 - Save Arrays Using The Settings System Object
Jan 14, 2009I just wondered if you can or can't save arrays using the settings system object. There seems to be no way of entering it at designtime. It seems implied you cannot create new user settings.subobjects at runtime. I'm looking to find the easiest way to save a populated array of PictureBox's. If the only way is a self/custom made/managed .ini file then I need to know so i can start on that but I was hoping to use some of all this phaff in the new frameworks usefully.
View 3 Replies[2005] Pass Excel.Application Object To Shared-Addin By .Net?
Jan 22, 2009I currently need to build a Automation Add-in for Excel. This add-in will load a recordset from Database to Excel. I would like to have function A() that I input in Cell as a formular. This function A() call a the add-in to load the data from Database to Excel. The data should be a matrix. So that means I would like to set in Excel worksheet a range of data by just calling single function in a cell. (I am sure there should be some way to implement it)As I know if I develop a shared Add-in by VB(or VB.Net) and in the add-in, I can get an Object of Excel.Application. By this Excel.Application object, I can get full control of Excel inside the Add-in. That means if I define a sub that load datamatrix from database and using the Excel.Application object I can populate the data matrix to the Excel.
I have done much research on internet and I now have built a shared Add-in for excel. I should say this add-in works fine without invoke the Excel.Application Object that I have tested. But when I call the Add-in function that invode Excel.Application Object from Excel I got an error as below:
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Run-time error '2147467262'(*)

VS 2008 - Error With Arraylist In My.Settings - Object Reference Not Set To An Instance Of An Object
Mar 14, 2010The issue is when I try to add a new item to the ArrayList with the following code, it gives me an error:

Dim result As String = InputBox("New Filter Label:", "Label List")

Object reference not set to an instance of an object.
I'm not really sure what I'm supposed to be doing with this. It's a new setting I just added and it's empty, so I'm not sure if that has anything to do with it or not. Anyone know what's going on and what needs to be done to get it to accept a value and not want to be "initialized"?
Function - Pass Object Versus Reference Object In Parent?
Dec 1, 2011I 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

My.settings Complex Object Is Nothing
Mar 26, 2010I'm trying to save some settings in a complex object. If I make a dll of the class I can then add it in the projects properties settings list as that type.When the program runs though it won't show up as anything other than nothing. I read you have to have a sub new empty constructor which I have but don't know why else this would fail.First question is how to you do this. Second is there anyway to use a class inside the project as the target of the settings type or do you have to bring a in an external dll to do this every time? [code]

View 4 RepliesObject Must Pass Itself As A Parameter?
Sep 10, 2011I 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.

Pass Object Between Asp.net Applications?
Jan 6, 2012We 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)?
Pass Out An Object Array In .NET?
Mar 25, 2011I'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.
Dispose Of Application Settings Object?
Dec 28, 2009I have a custom settings file that I designed using the designer. In my form, I have a function that creates a new instance of this settings by using a dim statement. Then I add this new settings object to a hashtable. After I exit this function, I no longer have access to the settings object without using the hashtable to retrieve it. If I want to remove the object from the hashtable, I can do a simple remove but the settings object still exists somewhere in memory. How can I dispose of this object as well since it inherits from ApplicationSettingsBase and does not have a built in Dispose() function?
View 5 RepliesUser Settings XML Serialization Of An Object?
Jul 17, 2009I am trying to save a custom object as a user setting in a VB.net app. This object consists of a List(Of Pair(Of String, Object)). Pair is a custom class which has two read/write properties (a String and an Object).
If I put simple types like int, string, datetime as the second value of my pair, the setting is saved without any problem. But if I try to put something more complex, like a list, there seems to be a problem during serialization and my setting is not saved.
String values in my pairs are serialized like this:
<value1>Priority_1</value1>
Object values are serialized with a special attribute:
<value2 xsi:type="xsd:int">2</value2>
Seems like values of type Object are serialized differently, to "remember" what is the real type of the object. Why can't it do the same for more complex types like List(Of T)?
Asp.net - Pass An Object Into A UserControl In A Repeater?
Jul 24, 2009I want to wrap up a chunk of HTML render logic in a User Control. Then I want to pass a custom product object (title, thumbnail, id, etc.) to the UserControl that it can use when it renders. Ideally I want to use this in a repeater (or for loop) and pass the current custom product object into the UC.Every example I've seen has been passing through strings on the UC tag but thats not really want I want to do as it means I'll have references everywhere that need updating should we add a new field that needs rendering.

Call A Method And Pass In An Object?
Apr 21, 2012I have a method called ADD in a class that connects to a database. The database class name is XDB. I also have an object named XXX in it's own separate class with properties.One of the instructions for the Button named ADD click event is:
'Call Add method passing in the XXX object
So this is how I coded:
'declare a variable X as an object instance of XXX

Correct Way To Pass The Graphics Object?

Private Sub DrawMap(ByVal e As System.Windows.Forms.PaintEventArgs)

Dynamically Pass Values To An Object?
Mar 28, 2011How 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

Asp.net - Use A Dictionary-like Collection As An Application Settings Object?
Jun 8, 2009I'd like to store a set of key/value pairs in the application settings of my ASP.NET web app, but I'm not finding a straightforward way to do that. For example, these two questions tell me that StringDictionary etc. won't serialize to XML and suggest that I'll have to roll my own implementation. But it seems like this should be easier to do; after all, web.config is XML and < applicationSettings> is essentially a collection of key/value pairs, so it feels like I'm missing something obvious. Given my specific case below, do I really have to roll my own serialization, or is there an easier workaround?
The web app in question is a basic contact form that sends email to different recipients based on the value of a parameter; e.g. [URL]...The goal is to be able add or remove recipients (or change their addresses) by editing the web.config file so that I don't have to recompile and can easily maintain different configurations in test and production environments. For example:
// I can use something like this for the sender address SmtpMsg.From = New MailAddress(My.Settings.EmailSender)
// And then just edit this part of web.config to use different addresses in different environments.
<setting name="EmailSender" serializeAs="String"> <value>webcontact@exampledomain.com</value>

Anyway, My problem is that I have a Setting from "My.Settings.Navigation" that is a Specialized String Collection, and what I am trying to do is find a method in which I can attach "My.Settings.Navigation" to a ComboBox. I was also wondering if it was possible to make it only hold up to 20 items at a time?
