Merge 2 strings and read variable that is created

Hi - interesting one (and possibly easy to solve)...

I am writing some vba for a custom outlook form - and as part of the validation process the code runs through a number of checks, ticking box's here and there... once it's checked the box's it will create a custom error message advising the user the parts they haven't done correctly.

The (cut-down) code is as follows

Sub ValidateTop_2
	if (_
		 VAL_T_01.value and _
		 VAL_T_02.value and _
		 VAL_T_03.value and _
		 VAL_T_04.value and _
		 VAL_T_05.value and _
		 VAL_T_06.value and _
		 VAL_T_07.value _
		) then
		T_PASS.value = true
	else
		T_PASS.value = false
		OOO_T_ErrCode = "TOP SECTION ERRORS"
		
		for x = 1 to 7
			set valbox = MP.Controls("VAL_T_0" & x)
			valerr = "OOO_T_ValErr" & x
			if valbox.value = false then
				OOO_T_ErrCode = OOO_T_ErrCode & chr(10) & valerr
			else
			end if
		next
	end if
	
	MsgBox(OOO_T_ErrCode)
End Sub

Open in new window

In the 'for loop', this checks to see if the user has passed each step (populated via a previous sub) - if they have T_PASS is ticked. if they fail, an error message is generated with custom "you haven't completed x" strings (OOO_T_ValErr1, OOO_T_ValErr2 etc)

As it loops through, it sets the VAL_T_01/VAL_T_02 etc variable absolutely fine and reads the relevant field as it needs to. But I'm trying to get it to loop through the error message variables, but it returns as a new string...

Any ideas how to merge the two and read the specific variable it refers to?

OK, I think I see what you're doing. I think what you're looking for is the equivalent of the Eval function in VBScript. but sadly, that doesn't exist on VBA, but you can use a Dictionary object for keys and pairs. The code below should do what you're after.

Regards,

Rob.

Private Sub CommandButton1_Click()
    Set dctErrors = CreateObject("Scripting.Dictionary")
    dctErrors.Add "OOO_T_ValErr1", "Full name of mailbox owner has not been provided"
    dctErrors.Add "OOO_T_ValErr2", "NT Username of mailbox owner has not been provided"
    dctErrors.Add "OOO_T_ValErr3", "Requestor's name has not been provided"

    If ( _
         CheckBox1.Value And _
         CheckBox2.Value _
        ) Then
        T_Pass.Value = True
    Else
        T_Pass.Value = False
        OOO_T_ErrCode = "TOP SECTION ERRORS"
        
        For x = 1 To 2
            Set valbox = UserForm1.Controls("CheckBox" & x)
            valerr = "OOO_T_ValErr" & x
            If valbox.Value = False Then
                OOO_T_ErrCode = OOO_T_ErrCode & Chr(10) & dctErrors(valerr)
            Else
            End If
        Next
    End If
    
    MsgBox (OOO_T_ErrCode)
End Sub

Hi, I built a sample in Excel, but it worked pretty much identically to what you have...

Thanks Rob - yes, it does pretty much the same thing unfortunately... if it helps, the below declarations/set commands are run:

dim OOO_T_ValErr1
dim OOO_T_ValErr2
dim OOO_T_ValErr3

Open in new window

OOO_T_ValErr1 = " - Full name of mailbox owner has not been provided"
OOO_T_ValErr2 = " - NT Username of mailbox owner has not been provided"
OOO_T_ValErr3 = " - Requestor's name has not been provided"

Open in new window

So if it fails at a specific point, the error message that should appear - is the one assigned to the relevant variable... not the variable name!
