Hi,
. Since learning here the basic idea about Microsoft Scripting Runtime Dictionary, I have been able to use it successfully for sorting and re organizing lists, particularly where unique values come into play..
. I have read time and time again that all sorts of information can be stored using the Microsoft Scripting Runtime Dictionary, and so I am considering it as an alternative to storing complete Range info as I have been able to do, for example, by creating an Array of Range Objects.
. All my attempts have been unsuccessful to date. I expect I am missing some fundamental points but all googling suggests it should be possible but I have yet to see concrete examples of how to do it.
. Can anyone set me straight or point me in the right direction on this one?
. The following is a simplified example of one of my failed attempts:
. – I consider a Simple spreadsheet with 7 hyperlinks, one in each cells, for cells A21 to A27
[Table="class: grid"][tr][td] [/td][td]
[tr][td]
[tr][td]
[tr][td]
[tr][td]
[tr][td]
[tr][td]
[tr][td]
[tr][td]
[tr][td]
[/table]
(In my actual sheet these are all hyperlinks which open a Web page when they are clicked on)
. With the code below I attempt to create a simple Microsoft Scripting Runtime Dictionary with 7 entries. The key I assign to the name (Value) of the Hyperlink in the cell, and I attempt to set the item to the Cell as a Range Object.
. There are 3 main parts to the code.
. 1). The background stuff to setting up the Dictionary. I have used this many times when using the Microsoft Scripting Runtime Dictionary for simple values and think it is still applicable to what I am trying to do here.
. 2) A loop to attempt to store the keys and corresponding Range Objects
. 3) A second loop to attempt to retrieve the range objects and put them in an Array of Range Objects
. Observations in the Watch Window show me clearly that 2) and 3) are only dealing with values rather than range objects.
( . 4) Finally the attempt to output the Range confirms that I only have values (Indeed I expect this simple method for outputting an Array in one go might not work fro an Array or range Objects and would possibly need to be replaced by some looping method anyway.?)
. Any help would be appreciated
Thanks
Alan Elston.
