How to pass the name of a Bolean variable in a String Variable and then Use that String Variable as a Replacement for the Name of the Boolean Variable in Code
This question is related to another question I asked on the Forum today and which was very kindly answered by Idle_Mind.
I have a Global Boolean variable in my project in a Visual Basic .NET Project named YesNo01. This YesNo01 is declared in a Module1 of my Project.
I wish to write some code along the following lines
1. If YesNo01 = True Then
2. MessageBox.Show (“YesNo01 = True”)
3. Else
3. MessageBox.Show (“YesNo01 = False”)
4. End if
However I do not want to use the actual Name of YesNo01 in statement No 1. Instead I wish to say something like the following:
Dim myString as String
myString = “YesNo01”
If myString = True Then
MessageBox.Show (“YesNo01 = True”)
Else
MessageBox.Show (“YesNo01 = False”)
End if
Thank you for your help in anticipation.

You can use a Dictionary:
Dim variables As New System.Collections.Generic.Dictionary(Of String, Boolean)
...
variables.Add("YesNo01", True)
...
Dim myString as String
myString = "YesNo01"
If variables(myString) = True Then
MessageBox.Show ("YesNo01 = True")
Else
MessageBox.Show ("YesNo01 = False")
End if
The most ~direct~ route would be using a Dictionary as kaufmed suggests. The Reflection approach I posted in your last question can't really be shortened. It can be placed into a function I suppose...
How are you going to use this? What is the "big picture"?

Excellent many thanks.
Idle_MInd the big picture is hard to explain briefly, but in my code somewhere I need to check if one of the several YesNo01 variables is true before the rest of the code runs. I cannot tell the code directly in advance which of the several YesNo variables (YesNo1, YesNo02 etc ) my code should check the value of before running further, but I can provide my code the value of YesNo variable it should check through a string variable. Hence these two questions related in theme. Many thanks both of you for your kind help.
