Safe Arrays question

Posted on 2004-09-21
Last Modified: 2008-05-29
I am taking xml data from a web service (data is good) and loading it into a dataset.

Here is the code that does that:
 procedure TForm1.GetDataFromWebService(AStrXMLDoc: string);
  XMLTransform1.TransformationFile := 'sites.xtr';
  XMLTransform1.SourceXml := AStrXMLDoc;

  ClientDataSet1.XMLData := XMLTransform1.Data;

For some reason that code is throwing esafearraylockederror-variant or safe array is locked.   I cant find anything about this sucker.   any ideas folks?

Try->  var before the parameter
Your sending a pointer and if the origin string destroys, the pointer lose its values
procedure TForm1.GetDataFromWebService(var AStrXMLDoc: string);
  XMLTransform1.TransformationFile := 'sites.xtr';
  XMLTransform1.SourceXml := AStrXMLDoc;

  ClientDataSet1.XMLData := XMLTransform1.Data;

Good luck

It is caused by a corrupt midas.dll.   I also found answers in google groups that showed this fixed this error for other people as well.  
First: startmenu->run->regsvr32 /u "c:\windows\system32\midas.dll"
Then: Update your midas.dll in c:\windows\system32 (for XP, other windows versions vary) and startmenu->run->regsvr32 "c:\windows\system32\midas.dll"
