I have a VB class inside which one of the methods accepts an array of forms. For each form inside the array, I need it to traverse all of the objects, check if they are a specific tyoe (input, label, checkbox, etc.) and get the properties of each object. Then, I want to dump these into a text file in the following format:
[Code]...
Lets say I have 30 text fields in a Frame on my form, and I want to set them all to disable (so users can't edit them).Is there an easy way to walk through those fields without having to create an array of text fields?
I.E., in ... VB 6, with an array of text fields, I can do something like this:
For i = 0 to 10
txtfield(x).enabled = true.
Next i
Is there something in VB.NET where I won't have to use an array of controls, something like this (assuming all txt fields are in a frame):
[Code]...
If I have a List(Of x) and a List(Of y) is it possible to iterate over both at the same time?
Something like
for each _x as X, _y as Y in List(of x), List(of y)
if _x.item = _y.item then
'do something
end if
next
These lists may be of differing sizes. I am using .Net2.0 which I suspect is my downfall here as I have a feeling LINQ would solve something like easily by joining the lists on there common id.

I'm fairly new to the concepts of OO programming - actually programming in general as I am still a student. I'm currently working as an intern in a department that has me coding a new structure that will probably be the base for all their applications to come. So I believe I have the idea behind OO down where you create "basic building blocks" and then expand, expand and expand, until you arrive at the most complex object (for the time being). I need to put all these "advanced" objects into one but how many is too many? Can I have 100 objects inside of this bigger object if it requires all these "parts".I really hope this question makes sense to everyone. I'm sure the answer is not going to be a definite answer either but I just need a rule of thumb to go by. I'd really hate to have 100 objects inside of 1 big one if there is a better design/programming technique. [code]

I am new to using Visual Basic 2008. I have been programming in VBA for years. In VBA I used the following type of 'For ... Next' statement to go thru multiple controls in a form which are named the same except for a number at the end of the control name. [code]...
View 3 Repliessay you have a sub containing an io.streamwriter. That streamwriter is declared and used only inside that sub (and not as static). Should you still call dispose on that streamwriter or is it disposed automatically as it is no longer in use after that sub, until you call that sub again?

View 4 RepliesI'm currently working on binding an objects properties to fields on a Form. Whilst I have managed to get it so that I can get standard objects to bind, I am having a problem figuring out how I would go about binding an inherited object.
For example, if I had a Client class (the parent class) and then two sub-classes called CompanyClient and IndividualClient. The CompanyClient would have an extra field company name for example.The problem I'm having is that I'm not certain how to set up the binding, as if I set up the binding against the Client class then I would be missing the Company Name property for the CompanyClient, if I set up against the CompanyClient, then it wouldn't work with the IndividualClient as it doesn't have all the fields.
I know I could get around this by having different forms for each of the different Client types, but as almost all of the properties are the same I would like to avoid this if I can.I was wondering whether anyone knows how I might be able to go about doing this
