MS Office Forum / Word / Programming / May 2006empty document variables
Hi, XML Word format, I set these variables: <w:docVars> <w:docVar w:name="myVar1" w:val="Kibo" /> <w:docVar w:name="myVar2" w:val="Xibo" /> <w:docVar w:name="myVar3" w:val="Jaffo" /> ;-)))) getting loving these... <w:docVar w:name="myVar4" w:val="" /> <w:docVar w:name="myVar5" w:val="" /> </w:docVars> In the document, I have fields that refers to these variables. However, the variables with empty strings are not present in the document! The field reports an error and ActiveDocument.Variables.Count returns 3. How can I set the variables to empty string? Thanks, Jan > Hi, XML Word format, I set these variables: > <w:docVars> [quoted text clipped - 11 lines] > > How can I set the variables to empty string? You can't. It is a holdover from the days before VBA when the method of deleting a variable was to set it to a blank string. The nearest you can get is to set it to a single space, and manage your code so that a single space is treated as an empty string.

But why is the Word then saving variables with empty strings...... Thanks for pointing that out before I get mad :), Jan. Jan Kucera was telling us: Jan Kucera nous racontait que : >> You can't.

A string containing a space is not an empty string... ;-) SignatureSalut! _______________________________________ Jean-Guy Marcil - Word MVP jmarcilREMOVE@CAPSsympatico.caTHISTOO Word MVP site: http://www.word.mvps.org > Jan Kucera was telling us: > Jan Kucera nous racontait que : [quoted text clipped - 8 lines] > > A string containing a space is not an empty string... ;-) I think the question Jan was asking is why, if when you set a Variable to an empty string and it therefore disappears from the Variables collection in VBA, does the tag of the Variable still appear with empty content when you save the file as XML? And I have no definite answer. I suspect it is a bug.

I suspect it is a bug. Yes Jonathan, that was the question - thanks. ;-) However you wrote a new information to me - when I set the variable to the empty string, it will be deleted? I was sooo near using Variables.Add("myVar", '") just to define it and set later...

Yes. At least, it will disappear from the Variables collection in VBA. As you have seen, the matching XML tag seems not to disappear.
