Hello All,

I use the following code which loops through all fields on my user form,
searching for any text box that does not contain data.

Question: How can i modify this code such that only some of the fields are
searched for missing data, rather than all. Reason: on my user form, 40 of
the 60 text boxes are required entry, and i want to make sure those fields
contain data.

Dim ctrl as Object
for each ctrl in Userform1.Controls
if typeof ctrl is msforms.combobox then
if ctrl.Value = "" then
msgbox "Missing Data in " & ctrl.Name
exit sub
end if
end if
Next

The body of your message says you have TextBoxes, but your code says
ComboBoxes. Either way... if the names for the controls that must be filled
in are unique in some way from the names for the controls that can be empty,
then you can modify your 2nd IF statement like this...

If ctrl.Value = "" And ctrl.Name Like "*uniquenamepart*" Then

If you unique name part come at the beginning or end of the name, you can
omit the asterisk at that end in the Like pattern string. If your naming
convention is not that structured, you can place the same text string in the
Tag property of those controls that must be filled in and then test for it
in the 2nd IF statement. For example, let's say that you put XX in each Tag
property for the controls that must have something filled in them; then your
2nd IF statement would look like this....

If ctrl.Value = "" And ctrl.Tag = "XX" Then

Hi Rick,

This worked fantastically well. Is there a way i can do the same thing for
all fields accpeting numeric data only?

Any assisstance would be really appreciated.

Do you mean you want to check if a number was entered in a field instead of
something with a mixture of letters and digits? Well, depending on what your
program is doing with the entry, you might be able to use VBA's built-in
IsNumeric function.

If Not IsNumeric(ctrl.Value) Then
MsgBox "Enter numbers only in " & ctrl.Name & "!!!"
Exit Sub
End If

Is that what you were referring to? By the way, I said "depending on what
your program is doing" above... the reason I said that is if your program is
dependent on a number looking like a number (digits only, coupled perhaps
only a decimal point), then IsNumeric might not be the way to go. Consider
this previous post of mine from the compiled VB newsgroups... everything
should apply from it with the possible exception of the method I use to get
the regional decimal point setting (although I think it is applicable to the
Excel world too).

From a previous post of mine...

I usually try and steer people away from using IsNumeric to "proof"
supposedly numeric text. Consider this (also see note below):

ReturnValue = IsNumeric("($1,23,,3.4,,,5,,E67$)")

Most people would not expect THAT to return True. IsNumeric has some "flaws"
in what it considers a proper number and what most programmers are looking
for.

I had a short tip published by Pinnacle Publishing in their Visual Basic
Developer magazine that covered some of these flaws. Originally, the tip was
free to view but is now viewable only by subscribers.. Basically, it said
that IsNumeric returned True for things like -- currency symbols being
located in front or in back of the number as shown in my example (also
applies to plus, minus and blanks too); numbers surrounded by parentheses as
shown in my example (some people use these to mark negative numbers);
numbers containing any number of commas before a decimal point as shown in
my example; numbers in scientific notation (a number followed by an upper or
lower case "D" or "E", followed by a number equal to or less than 305 -- the
maximum power of 10 in VB); and Octal/Hexadecimal numbers (&H for
Hexadecimal, &O or just & in front of the number for Octal).

NOTE:
======
In the above example and in the referenced tip, I refer to $ signs and
commas and dots -- these were meant to refer to your currency, thousands
separator and decimal point symbols as defined in your local settings --
substitute your local regional symbols for these if appropriate.

As for your question about checking numbers, here are two functions that I
have posted in the past for similar questions..... one is for digits only
and the other is for "regular" numbers:

Function IsDigitsOnly(Value As String) As Boolean
IsDigitsOnly = Len(Value) 0 And _
Not Value Like "*[!0-9]*"
End Function

Function IsNumber(ByVal Value As String) As Boolean
' Leave the next statement out if you don't
' want to provide for plus/minus signs
If Value Like "[+-]*" Then Value = Mid$(Value, 2)
IsNumber = Not Value Like "*[!0-9.]*" And _
Not Value Like "*.*.*" And _
Len(Value) 0 And Value < "." And _
Value < vbNullString
End Function

Here are revisions to the above functions that deal with the local settings
for decimal points (and thousand's separators) that are different than used
in the US (this code works in the US too, of course).

Function IsNumber(ByVal Value As String) As Boolean
Dim DP As String
' Get local setting for decimal point
DP = Format$(0, ".")
' Leave the next statement out if you don't
' want to provide for plus/minus signs
If Value Like "[+-]*" Then Value = Mid$(Value, 2)
IsNumber = Not Value Like "*[!0-9" & DP & "]*" And _
Not Value Like "*" & DP & "*" & DP & "*" And _
Len(Value) 0 And Value < DP And _
Value < vbNullString
End Function

I'm not as concerned by the rejection of entries that include one or more
thousand's separators, but we can handle this if we don't insist on the
thousand's separator being located in the correct positions (in other words,
we'll allow the user to include them for their own purposes... we'll just
tolerate their presence).

Function IsNumber(ByVal Value As String) As Boolean
Dim DP As String
Dim TS As String
' Get local setting for decimal point
DP = Format$(0, ".")
' Get local setting for thousand's separator
' and eliminate them. Remove the next two lines
' if you don't want your users being able to
' type in the thousands separator at all.
TS = Mid$(Format$(1000, "#,###"), 2, 1)
Value = Replace$(Value, TS, "")
' Leave the next statement out if you don't
' want to provide for plus/minus signs
If Value Like "[+-]*" Then Value = Mid$(Value, 2)
IsNumber = Not Value Like "*[!0-9" & DP & "]*" And _
Not Value Like "*" & DP & "*" & DP & "*" And _
Len(Value) 0 And Value < DP And _
Value < vbNullString
End Function
