I am using the other DarkGDK.NET and faced the same problem. My data consisted of X/Y pairs such as;
PTDATA:
DATA 123.45, 678.90
What I did was cut and paste all of my data to a textfile using NOTEPAD and then did a search and replace until the data looked like:
123.45, 678.90
.
.
etc.
Then I saved it as "datapnts.txt"
I then used the following code in VB to read the file to an array:
Dim x1 As Double
Dim y1 As Double
path = System.Windows.Forms.Application.StartupPath.ToString
DarkGDK.IO.File.SetCurrentDirectory(path + "\data\")
Dim TempFile As DarkGDK.IO.File
TempFile = New DarkGDK.IO.File.OpenToRead("datapnts.txt")
Do While TempFile.IsEOF = False
TempFile.ReadFloat, x1
TempFile.ReadFloat, y1
pathpts(I).x = x1
pathpts(I).y = y1
Loop
TempFile.close()
