Persistently Change A Control's Properties At Runtime

Oct 29, 2011

i've written an app to enumerate forms + controls in a project at runtime:

it lists form names in a listbox + when a control is selected, it lists hierarchical controls in a treeview. by selecting a control in the treeview you can view its properties in a propertygrid.

here's the problem: how can i use the propertygrid to actually persistently change those properties?

at the moment you can change properties in the propertygrid but it doesn't change the control's properties, either persistently or otherwise.

here's the code. (you can download the full project at: [URL]

Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ListBox1.Items.AddRange((From t As Type In Me.GetType().Assembly.GetTypes() _
Where t.BaseType Is GetType(Form) _

Looping Though The Properties Of A Control At Runtime?

Apr 11, 2009

How can I read the properties for a given contol type at runtime without having the masive overhead of specifing the each property for each type of control in code.

For example supose you are building an application where the end-user selects a contol type form a drop-down list in a combobox then the properties (Read, Write, Runtime, Designtime) for that control are displayed in a listbox.

I want to program a water supply pipeline network in a treeview control. It has five node (junctions). The parent-child relation is based on a parameter (say pressure).

User Control Properties - Finalize My Design Time Properties Grid

Apr 27, 2011

I'm making a control and I am trying to finalize my design time properties grid. I have several List(of Class) items as public properties and when I click on the design time menu (while testing the control) there is the word "Collection" and a button with an ellipsis (...) that brings up a neat pop up with the buttons Add/remove and all of the public properties of the collection's class on the right hand side. Basically for a non-collection instance of a class (with public properties) I'd like a similar button to show up. I know I could put all of the properties in the main control class and group them, but I like the pop up box feature. Anyway to duplicate this? (think font grid item etc.)

ASP.NET - Ascx.designer 'properties' Not Showing Up In Reflection At Runtime

Jul 2, 2010

I have a very simple setup, single mycontrol.ascx with assoicated mycontrol.ascx.designer.vb and mycontrol.ascx.vb file.

mycontrol.ascx embeds a single reference to a custom control: "MyMenu":

<mM:myMenu id="myMenu1" runat="server" />

This has created a protected reference in the mycontrol.ascx.designer.vb file:

Protected WithEvents myMenu1 As Global.CustomControls.MyMenu

Now, when I breakpoint the Page_Load() event of mycontrol.ascx, and inspect the members returned from the type via:

Me.GetType().GetMembers()

I cannot any reference to myMenu1. If I look at the control with intellisence, the property is accessible:

Me.myMenu1

what I'm missing and what I need to do to access designer created properties at runtime through reflection?

Setting Properties Of A SSIS DTSX Package At Runtime From VB?

Sep 14, 2009

i am writing a VB front end (VS 2008 .NET 3.5) to a data loading program that involves moving the contents of CSV flat files into SQL Server 2005 staging tables. I have had some experience with DTS in SQL 2000 so I decided to use SSIS packages to load the CSV data. Creating the packages in BIDS worked fine for the development environment where I hard-coded the Connections and file paths. The problem arises when I will release this program to 30 different sites that do not have SQL Server admins to help changing the configuration.

I have a SQL table in which I will put all the necessary path information and I can pull that into the VB program on startup. I need to see an example of how I can set the properties from VB once the package is instantiated and opened.Here is an example of where I plan to set those properties and run the packages.

Private Function RunPackages() As Boolean
Try
Dim oApp As New Application
Dim oPackage As New Package

[code]....

Even though I am using a configuration file in the example, I am finding it difficult to edit the configuration files for each site. I see that there are methods and properties exposed for the oPackage instance. However, I can't find a good reference for the Class model to use as a guideline. All the examples expect packages to be run and configured with SQL Server and BIDS. direct manipulation of package properties in VB or C#?I am now considering using the old standby SQL Bulk Insert. It almost appears as if the Data Tasks are just wrappers for the Bulk Insert operation. Furthermore we have several sites still using SQL Server 2000. With the economy the way it is, most of those sites do not want to spend ANY extra money upgrading to SQL 2005 or 2008.

However, having a good resource to learn how to manipulate SSIS packages from the CLR would be very helpful. I have heard that in SQL 2008 things have changed even more. It is maddeneing that once I learn a "new" Microsoft technology it seems to be discarded by MS in their next release in favor of a "better" alternative.

VS 2008 Accessing Button Properties Made In Runtime?

Apr 6, 2010

how to handle movement of buttons that are made in runtime. What my program does is writes the name of a button that is made in runtime, the left, and top cordinate into a textfile. When the user reopens the program it needs to load the button in the same spot. So far i have a streamreader reading the file in each line. There is a one sentence split by ",". Each of the three components are loaded into an array. how can i call the buttons it i am unsure of the name. Possible answer could include using sender, addhandler.

Private Sub LoadBuildingToolStripMenuItem1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LoadBuildingToolStripMenuItem1.Click
