Hello.

I want to access a 2D array with only one Index.

This approach is made possible in "C++", I do not know how to in "VB"..

Thank you..

In C++>

C++

char cTestArr[2][10];
strncpy(cTestArr[0],"123456789\0",10);      // Data -> char array ( PASS! )
CString strTest(cTestArr[0]);				// char array -> CString ( PASS! )

In VB>

VB

Dim strTemp As String
Dim cTestArr(2, 10) As Char ' Must not be a String Type

cTestArr(0) = "123456789"   ' Data -> char array  ( FAIL!!! )
strTemp = cTestArr(0)       ' char array -> String ( FAIL!!! )

You don't. You have to use two indexes. In C, you can get away with it, but VB is a lot more strict.

The solution if you want to use one index is to make it a one dimensional array. You'll have to do some additional mathematical coding to access the array using two indexes and generate a single index value to get the correct item from the array.
