Cycling through all GUI Objects within a form

[karoitay]

I Have just recently heard about reflection and I'm quite not familiar with the subject. So... can you please hand me a little piece of code to show how can this be done so I will not have to read all about reflection. ( I'm a litle busy the next days any I need this job to be done as quickly as possible ). Thanks.

Don't you think, that this would bring a lot of useless matches (ListBox.Items). I think it would be easier to check out how many control classes don't match "Controls", and do a typecheck ("as") at them!

All the best, Martin

Since I don't know what the overall purpose is I can't say if that would bring lots of useless matches or not. It might do. It might not.

I wouldn't use reflection. I'd just test if the current control is of a type with a property Controls or whether it is of for example type ToolStrip: Or the make the code more readable, introduce several overloaded methods that take the different types as a parameter (one overload for control, one for toolstrip, ....) And call them recursively.

That may depend on how the enumeration is implemented.

Whould you mind explaining yourself?? Undefeated's explanation and suggestion is perfectly valid.

The Overall purpose is to have a dictionary that will map a Gui object to a bitmask to determine its accessibility to each user of the application

but it wasn't something that could be copy/pasted as is to do the OPs homework/job for him. Consequently it was worthless. :mad:

Gee, why didn't you say so. I'll get right on it. :rolleyes:

--- How to get answers to your questions[^]

[Colin Angus Mackay]

You can ask every object for its type with .GetType(). You get back a Type object. It has methods on it such as GetMethod, GetProperty and so on. You can get information from the objects those methods return MethodInfo or PropertyInfo and so on. If you find the one you want you can then Invoke it. Most of this should make enough sense through intellisense. You may have to look up some stuff in the documentation though. It really is worth reading up on so you have a better understanding of the environment in which you are working.
