Update Sorry. I didn't mean the whole reflection library was off limits. I just meant the insanely slow *.Invoke() stuff. Hi, I need to implement a property system in C# that allows both normal property access [property_attribute()] return_type Property { get; set; } and access by string SetProperty(string name, object value); obje...
I'm trying to read the value of a C# property from my code behind file into some JQuery script (see below). The JQuery selector I've written accesses an ASP.Net GridView and then a CheckBox field within the gridview. Whenever a checkbox is checked or un-checked the code is hit, but I need to access the C# property from the code behind ...

Is there any simple way to archive this with ListProperty and custom property's without going into pickled/simplejson blob data?

The goal is to create a mock class which behaves like a db resultset. So for example, if a database query returns, using a dict expression, {'ab':100, 'cd':200}, then I would to see >>> dummy.ab 100 So, at the beginning I thought I maybe able to do it this way ks = ['ab', 'cd'] vs = [12, 34] class C(dict): def __init__(self, ks...
I am trying to develop a simple interface for allowing quick lists to be generated from classes. Basically, the interface needs to return an ID and a Name. However, some classes have a calculated name property which is read only, others just use a read/write name property. Basically, all I care is that it has a getter, it does not matter...
I'm trying to create a point class which defines a property called "coordinate". However, it's not behaving like I'd expect and I can't figure out why. class Point: def __init__(self, coord=None): self.x = coord[0] self.y = coord[1] @property def coordinate(self): return (self.x, self.y) @coo...
I admit I am totally new to QT so bare with me. I am used to develop in Delphi, but I have recently moved to developing in Python and with that PyQT (later I'll switch to PySide). Anyway, I'm trying to figure out if there's anything in QT that is equivalent to Delphi's Align property possibilities like alTop, alClient, alRight and so on?...

The symptoms are that MMC.EXE crashes when selecting that property sheet tab. I tried attaching to mmc.exe, but although the property sheet displayed the tab, the DLL is not on the call sta...
Hello, I wish to allow the user of my control to choose the licensing method for the control. The choice comes from an enumeration, so they must choose one of the methods I have laid out for them. This license needs to be chosen prior to the code executing at runtime. Therefore I wish for them to selected a value at design time. Fu...

I want to execute a command that will take in "mod1" as one of the arguments. Moreover.. I cannot modify this original "module.list" property to a list or anything else.. although I can crea...
I want to be able to call a method that creates an object and sets properties of the object based on the parameters passed into the method. The number of parameters is arbitrary, but the catch is I don't want to use strings. I want to use the actual properties sort of like you do in lambda expressions. I want to be able to call the me...
