Set conn = Server.CreateObject("ADODB.Connection")
conn.Open "DSN=HMS"

set rsValidationRules = conn.execute ("SELECT * FROM VALIDATION WHERE VALIDATION_COMPONENT_ID="&componentID&" VALIDATION_CLIENT_ID="&clientID&" VALIDATION_USER_GROUP_ID="&userGroupID)
validationRulesArray = rsValidationRules.getRows()
%>
</body>
</html>


the error it gives me is

Microsoft VBScript compilation  error '800a0401'

Expected end of statement

set validationRulesArray = New validationRules()

 

by: JonMnyPosted on 2007-01-23 at 12:00:06ID: 18378454

try

set validationRulesArray = New validationRules

 

by: drunkenlogicPosted on 2007-01-23 at 12:47:04ID: 18378918

that works but it doesnt create an array of validationRulesArray.

i want an array of class validationRules

 

by: JonMnyPosted on 2007-01-23 at 12:50:45ID: 18378951

you can make it static like this

dim validationRulesArray(10)

or

dim validationRulesArray()


redim validationRulesArray(sizeneeded)


 

by: drunkenlogicPosted on 2007-01-23 at 12:59:58ID: 18379071

yeah but i want validationRulesArray to be of class validationRules

 

by: JonMnyPosted on 2007-01-23 at 13:06:11ID: 18379157

I think you will have to do somthing like this

Set validationRulesArray(0)  =  New validationRules  'do this for each item in array

Look here for another example

>yeah but i want validationRulesArray to be of class validationRules

That's impossible in VBScript, it can only be done in VBA or full Visual Basic.  What you really want and can get is an array filled with validationRules.

Your script is horribly wrong for doing this.  Try this:

Dim validationRulesArray()
Dim numArrayRows
Set conn = Server.CreateObject("ADODB.Connection")
conn.Open "DSN=HMS"
set rsValidationRules = conn.execute ("SELECT * FROM VALIDATION WHERE VALIDATION_COMPONENT_ID="&componentID&" VALIDATION_CLIENT_ID="&clientID&" VALIDATION_USER_GROUP_ID="&userGroupID)
numArrayRows = 0
Do While Not rsValidationRules.EOF
    numArrayRows = numArrayRows + 1
    Redim Preserve validationRulesArray(1 to numArrayRows)
    Set validationRulesArray(numArrayRows) = new validationRule
    validationRulesArray(numArrayRows).validationID = rsValidationRules.Fields("validationID").Value
    validationRulesArray(numArrayRows).validationComponentID = rsValidationRules.Fields("validationComponentID").Value
    validationRulesArray(numArrayRows).validationType = rsValidationRules.Fields("validationType").Value
    validationRulesArray(numArrayRows).validationCriteria = rsValidationRules.Fields("validationCriteria").Value
     validationRulesArray(numArrayRows).validationClientID = rsValidationRules.Fields("validationClientID").Value
     validationRulesArray(numArrayRows).validationUserGroupID = rsValidationRules.Fields("validationUserGroupID").Value
    rsValidationRules.MoveNext
Loop
conn.Close

This will actually do the job as long as the property names of the validationRule object match the field names of the field values they are being assigned.

the above code doesnt work and what do you mean by each item in array?

 

by: cpkilekofpPosted on 2007-01-23 at 13:18:31ID: 18379313

Which above code doesn't work?

validationRulesArray(1) is one item in the array.
validationRulesArray(2) is another item in the array.
etc.

 

by: cpkilekofpPosted on 2007-01-23 at 13:20:35ID: 18379332

Also, what do you mean when you say "it doesn't work"?  A specific error message tells us what happened, "doesn't work" tells us nothing (the error could be unrelated to the code change, or could be caused by a typo, for instance).

 

by: JonMnyPosted on 2007-01-23 at 13:22:50ID: 18379351

You create the array

Do While Not rsValidationRules.EOF
    numArrayRows = numArrayRows + 1

then while reading through the database you set each item in the array to a "New" instance of validationRules

Set validationRulesArray(numArrayRow)  =  New validationRules  'this will create an instance of the class

 

by: cpkilekofpPosted on 2007-01-23 at 13:40:05ID: 18379559

*smacks head* I missed the s at the end of New validationRules.  A typo, as I said.

 

by: drunkenlogicPosted on 2007-01-23 at 13:50:51ID: 18379703

anyways thanks
