Combine 2 Arrays Into Single Array?

[nico3334]

Hi, I have 2 arrays (Each As a String), and I would like to combine these into a new single array. Is there an easy way of coding this? For example, I want "arrData" and "arrID" to be combined into a new array: "arrTotal". If anyone could give me some coding examples, I'd greatly appreciate it. Thanks!

This has a ArrayMerge solution that might be just what you need:

Can you be more speciifc about what you mean by "merged"? Do you want the corresponding values in the arrays to be concatenated/added/multiplied/combined in some way? Do you just want the two arrays to be stuck together "end to end"? Should the values be "interleaved"? Show us some samples of what sort of thing you mean.

Also, what version of VB are you using?

Thanks for your replies. I'm using VB 6.0. I basically am building 2 separate "tables" that are being filled with data from a SQL table. The first array bascially contains descriptive data and the 2nd array contains numerical quantitative data. I'm adding SQL data into each array using .movenext and loop. So, I have both arrays containing the data, and I would like to combine them as a new "table". So, nothing will be added or calculated, just a combined new array that contains all the data. Thanks!

Hi,

u want a combined resultant array with Distinct Values of both the arrays..? or Simply Merge without any condition...?
If both the array data is in 2 Tables, then u can just get the Results thru SQL Query, u dont have to Populate an array and combine,
Some Query Like :

Select Col1 From Table1
Union All
Select Col1 From Table2
 

REgards

SELECT (tblTableName1.MrgColumn & tblTableName2.MrgColumn) as CombColumn 
FROM tblTableName1 INNER JOIN tblTableName2 ON tblTableName1.IDfield = tblTableName2.IDfield

Just explain you want to ADD one by one or merge columns?

I'm still a bit confused about what is to be in the combined array. Could you show us just a little sample of some data, before and after.

If the "combined" array is supposed to hold some sort of one-to-one relationship (this descriptive-text <=> this numeric-value) then perhaps the simplest would be to define an array (or collection) of a user defined type which holds the two pieces of information. For example...

Public Type MyStuff
  DescTxt As String
  NumVal As Long
End Type
Dim MyArray(1 To 10) As MyStuff
 
With MyArray(1)
  .DescTxt = "The first descriptive text entry"
  .NumVal = 1234
End With
 
' And so on...

I think He Means...

Dim 1 = abc
Dim 2 = def

3 should be 1 joined to 2 so...
3 = abcdef

You may be right waffles. However, it may also be a bit late. That last post of mine was almost 5 years ago, and the OP doesn't appear to have been active here for almost that long.
