richTextBox1.SelectionStart=GetSelectionStart(5,3)
richTextBox1.SelectionLength=10
'to set cursor to specific line just pass 0 in column no and set seletionlength to 0
Public Function GetSelectionStart(nLine as Integer,nColumn as Integer ) As integer
Dim nIndx As Integer
Dim nSelectionIndex as Integer=0
Dim sLines() As String =richTextBox1.Lines
For nIndx=0 To sLines.Length -1
nSelectionIndex+=sLines(nIndx).Length
Next
return nSelectionIndex+nColumn
End Function

Thank you one more time, i also rewrite it in c# with some modification, so it can throw exception if you try to select something in empty line...
public
int SetPosition(int linija, int kolona){
int doKade = 0; string[] lini = richTextBox1.Lines; if (lini[linija-1].Length == 0){
throw new Exception("Empty line");}
for (int i = 0; i < linija -1; i++){
doKade += lini[i].Length+1;
}
return doKade + kolona;}
This was realy good piece of code, thank you for shearing it with me. It made me to learn litle VB so I can rewrite it in c# :)

for(nIndx=0;nIndx<sLines.Length ;nIndx++)

}
return nSelectionIndex+nColumn;
