View 1 RepliesI 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.
Consider a MyForm class that contains a shadowed implementation of Show(). It also contains a CreateForm() method, which accepts an instance of the form and calls the shadowed sub:

I've got this code here, hard coded into a button. What I want to do is create a module with a method, let's call it "openFile."
That way, in the future, I can just call openFile("default directory",file type, etc etc) and also being able to set the input from the reader as the text in a text box or something all in one line of code. Is this possible? I don't know anything about writing modules or my own methods/API or anything like that...Can someone point me to a tutorial about this?
Here's the
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim filesOpen As New OpenFileDialog()
filesOpen.InitialDirectory = ("C:") 'set the default directory

I'm working through a book that does not provide a lot of example code and what it does provide is in C#. The book refs vs 2005 but I'm using vs2008. The author asks for the user to create a solution with two projects, one winforms and the other a class library (called DependentAssm). The class library is added as a reference to the winforms project In the class library, he asks one to create a new class called SayHelloComp. The project created a file called class1.vb, and a class called class1 which I renamed to SayHelloComp. I left the file name alone, that's ok right?

For the last week I've been trying to create an async method. I tried the MSDN article How to: Implement a Component That Supports the Event-based Asynchronous Pattern but it does the work in a method in the same class. The work I'm doing is a lot more complicated and is its own class. The problem I'm having is the class doing the work cannot post the progress or completion as the methods that handle this stuff is in the parent class.

I wish to create a form with a translucent clientwindow but want to have all contained controls and the form border display as normal. Setting the form's Opacity level dims the entire form including its controls and this is not the effect I'm trying to achieve. I have achieved the desired effect by placing a second form behind the main form (with the main form's "TransparencyKey" property set) and adjust the background form's opacity level. This added a few issues to overcome in terms handling the z-order, handling click-through through the main form, and an additional form in the Alt-Tab sequence that I did not want.

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.
I want to create a custom control (let say textbox), after build, when I place that custom control on a form, all the properties for the default textbox are available.

2- Is there a Wizard or custom tool for creating custom control or I had to do every thing by coding?
I am learning vb.net and I am having trouble wrapping my head around the following... I can create several properties of a custom class and get/set values or I can create a method to set them all at once. If each property is going to allow read and write should I just make a method to assign values all at once? I assume that I am missing a very important piece here. Example: I can create 2 properties:

View 1 RepliesUse the "new" keyword to create an object instance & Check to determine if the object is null before calling the method. I'm reading text from a text file using the following [Code]
View 9 RepliesI need a bit of advice. I am working on my project with the listbox. I know how to create a source to get the strings from the text file using ReadLine method, but I have no idea how to split the strings in the text file by on the third commas and ignore the other strings while select with the matched strings on the listbox for each row.Here it is an example listbox Here it is an example items on the listbox
random item 1
random item 2
random item 3
random item 4
random item 5
And here it is an example text file.
example strings one, any strings 1, any random strings 1, other strings 1, final end of strings 1
example strings two, any strings 2, any random strings 2, other strings 2, final end of strings 2
example strings three, any strings 3, any random strings 3, other strings 3, final end of strings 3
example strings four, any strings 4, any random strings 4, other strings 4, final end of strings 4
example strings five, any strings 5, any random strings 5, other strings 5, final end of strings 5
The listbox is display the list of an example items, so if I select the "random item 1" item on the listbox, it read the strings through in the text file on the first line to get the strings on the third commas in the same line which it is (any random strings 1) to split it while ignore the other strings (other strings 1, final end of strings 1) that come fourth and fifth commas. So, if I select the "random item 2" item on the listbox, it read the the strings through in the text file on the second line to get the strings on the third commas in the same line which it is (any random strings 2) to split it while ignore the other strings (other strings 2, final end of strings 2) that come fourth and fifth commas and so on...That is what I am trying to achieve by select the each listbox item to get the correct strings for each line in the text file that come on the third commas while to ignore the other strings.
