DoorEx library

[agraham]

This library extends the functionality of the Door library. This first version implements a "FromString" method that will obtain the reference to either a Basic4ppc control or external library object when provided with the name of that control or object as a string.

The reason for providing this is that you can't indirectly address a library object using the Control keyword in an optimised compiled app because the optimised compiler needs the Control(name, type) form of the Control keyword and "type" cannot be a variable and so is limited to the one type of control specified at compile time. Using "FromString" you can get the reference and then get or set properties or run methods using the Door library.

EDIT : Version 1.1 posted. See post #6 for details

EDIT : Version 1.2 posted. With Erel's permission this library now includes all the original Door library functions so can it be used as a replacement for instead of alongside the Door library which makes some things a little easier. See post #11 for details.

Agraham it is great!big thanks!you are my Hero))

Sorry that I ask here...

obj.SetProperty("ForeColor",rgb(255,0,0))

return error

Object of type 'System.string' cannot be converted to type 'System.Drawing.Color'

how can i convert string to color? :-[

There's an example in Door help->Overview->Passing color value

If you thought the Door library was a bit arcane

I've been playing over the last couple of days passing things around between libraries and Basic4ppc code and have provided a few more things that made it easier to do some things with the Door library. The most useful for mere mortals is probably ValueToColor, "obj.ValueToColor = cRed" or "obj.ValueToColor = RGB(255,0,0)", which saves a lot of typing. See the help for details.

I won't attempt to provide a demo file for this. If the help is not enough then you probably need to learn more about .NET.

I am happy with GetProperty for collections indexed by keys but I have not thoroughly tested the SetProperty variants, but as the famous last words said "it should work" (but probably won't)

Erel once amusingly wrote to me in an email "However it wasn't checked and therefore it doesn't work ". I should frame that one really and put it on the wall As Richard Feynman wrote about the fine structure constant "it's something every physicist should write on their blackboard and worry about!"

I can't find the solution in any .NET searchs.


mycolor = "255,0,0"


Button1.Color = mycolor (Doesn't work)
Button1.Color = RGB(mycolor) (This too)

In my app, MYCOLOR isn't really a variable, but the foreground and background colors (in RGB) are in a Class Flag Color database table. The button color needs to change (and rechange) depending on the Class selected.

Could I have just a tiny, one line example of how to change color when the desired color is a TEXT item in a database?

You don't need to use any library for this.

Sub Globals
 Dim Type (R,G,B) clr
End Sub

Sub ...
 somestring = "255,0,0"
 clr() = StrSplit(somestring,",")
 Button1.Color = RGB(clr.R, clr.G, clr.B)

Erel,

Once again, thank you for your help. It's all so simple when you just know how.
