Custom ToolStripItems Painting - Draw Graphics Without Calling The Refresh Method?

Nov 11, 2011

I have created a custom ToolStripProgressBar. It is basically a class inherited from ToolStripStatusLabel, and i paint the 'progress' bar myself (just a simple rectangle). I have tried creating a custom ToolStripProgressBar using different methods including inheriting from both ProgressBar, ToolStripProgressBar and ToolStripControlHost. I always ran into difficulties doing in this way. Inheriting from ToolStripStatusLabel works well, but with one issue...

In order to have the progress bar update in the statusbar, i have to call StatusStrip.Refresh. Trouble is, adds a huge overhead to the drawing of the progress bar graphics. Simply calling the invalidate method of my ToolStripStatusLabel does not seem to render anything to the screen. how to have my graphics draw without calling the refresh method?

Method To Modify Value Of Property

Feb 18, 2011

I've got two classes deployed as COM+ components, let's say ClassA and ClassB. ClassA has some public properties. ClassB sets values for those properties and calls a method of ClassA. The method itself does not modify the value of the property. After the call the values of the properties are reset to default values for the corresponding types. This only happens if the called method includes statement ContextUtil.SetComplete(). Once I comment out the statement the values of the properties remain same as they were before the method call, which is what I expect. Do I overlook some basic concept of COM+ objects and their contexts? I would expect the property value to remain the same in any case.

Here's the simplified listing for the code:
Option Strict Off
Option Explicit On
Imports System.EnterpriseServices
<Transaction(TransactionOption.Required)> _
Public Class ClassA

Overloading A Property's Set Method?

May 12, 2012

maybe it's not a method exactly. here's what I'd like to do:

Private _Columns As ArrayList
Public Property Columns() As ArrayList
Get[code]....

which would allow me to conveniently set the property by assigning to it various kinds of collection types... except, I can't do it because apparently the Set method has to take an argument of the type of the property itself... I get the complaint:

'Set' parameter must have the same type as the containing property

is there a way to do this?

Inheritance - Create A Method Called StartWorking() And Want FrmChild To Inherit - Method

Nov 25, 2011

I have a large problem with inheritance in vb.net. The problem is the following:

I have 2 forms => frmBase and frmChild

In frmBase i want to create a method Called StartWorking() and i want frmChild to inherit this method.

But here is the tricky thing: when frmChild.StartWorking is called i would like the following => without calling MyBase.StartWorking()

I want frmBase.StartWorking() to be executed first and after a test in frmBase.StartWorking if blnValue is true then frmChild.StartWorking has to be activated. if blnValue is false that frmChild.StartWorking cannot be activated.

Use The ToString Method And A Counter To Concatenate A File Name Into A String Variable From The Image.FromFile Method?

Dec 18, 2010

I have nine pictures that I need to animate -I need to use the ToString method and a counter to concatenate a file name into a string variable from the Image.FromFile method. Once the counter reaches its maximum value, and the last picture is displayed, the counter should be reset to zero or one depending on how the first image file has been name. Also a static counter variable should be incremented in the time routine. what I have so far -- I know what I have to do; however, I just do not know how to code this properly.. Right now I have this going thru a button procedure but it needs to go through a timer.

Reflected Method From A Loaded Assembly Executes Before Calling Method?

Jun 9, 2009

When I am loading an Assembly dynamically, then calling a method from it, I appear to be getting the method from Assembly executing before the code in the method that is calling it.It does not appear to be executing in a Serial manner as I would expect. Can anyone shine some light on why this might be happening. Below is some code to illustrate what I am seeing, the code from the some.dll assembly calls a method named PerformLookup. For testing I put a similar MessageBox type output with "PerformLookup Time: " as the text. What I end up seeing is:

First: "PerformLookup Time: 40:842"
Second: "initIndex Time: 45:873"

Hide A Method/property For Intellisense?

Sep 28, 2009

I have a Class A that inherits from a base class. In the class A i have build some methods/properties.What I want is that some methods/properties from the base class are not visible in the intellisense which makes it easier for a developer. Basically i want to hide all the methods/functions/etc.. which are no use.Is this possible whithout having to use the EditorBrowsableAttribute for every item?The best way would be to tell the class that it must hide all props/methods/functions/etc... and after that i can specify which MUST be visible.

'by default hide all props/functions/etc.... ????

The Method 'X' Is Not A Property Accessor (Linq / LinqToSql)

Feb 15, 2011

I'm using LinqToSql classes in an ASP.NET website and let's say I have an entity named Testimonials. Two pages utilize this type - the first being a list of all existing Testimonial records and the second being an add / editor with which to manage the records. [Code] This allows population a DataGrid with the returned items, however on the add / editor page we alter the query ever so slightly: [Code] This query dies, prior to even trying to populate anything, with the following message: [Code]

I have pretty much identical methods for other data objects which have been and still are executing just fine. One immediate difference I can think of is that this table has been recently updated in the database, removed from the dbml designer and re-added to the dbml designer. None of the other tables have undergone this process for some time. [Code] Why is this exception occurring and how can I configure my project appropriately to correct the issue?

Create An UnInterface Making Sure That The Class Does Not Have A Method / Property

Dec 17, 2009

Interface makes sure a class does have a Method / Property, However is there a way to create an unInterface, making sure that the class does not have a method / property or is there a way to implement something that will unimplement every other implements except for itself?

what i want to do: i've got a class that serves as a storage for information only, so i decided to give it a blank interface IBank, the other classes that share this feature will implement this interface. they should not implement any other interface the use is that when i seek out the interface of a class and realise that its IBank i know that its just a class for info storage.
