From: hahoyer on 14 Nov 2005 05:51 Which part MFC/MSWindows creates the message "an invalid argument was encountered"? Why this message is usually created? How can I customize it, to a) throw an execption instead b) add more information on the environemt that created that message Greetings Harald
From: Tom Serface on 14 Nov 2005 10:38 I've seen this message in a few instances: 1. CTime used in CFile has a problem where it returns a time that is incompatible (0 I think) and that does error. I finally created my own version of CFile::GetFileStatus() that does a check like: if(nTimeTest != 0) rStatus.m_ctime = CTime(findFileData.ftCreationTime); else if(nWTimeTest != 0) rStatus.m_ctime = CTime(findFileData.ftLastWriteTime); else rStatus.m_ctime = CTime::GetCurrentTime(); I had this problem mostly when using Berlin,Germany since I think they are pretty close to GMT (certain times of the day didn't work). CTime seems to be really fussy about some times. 2. You get this message (and ASSERTS) if you have a control on a dialog that you delete, but the handler for the control is still in the DDV, DDX part in the dialog handler file.

From: Ajay Kalra on 14 Nov 2005 11:00 Its likely that an exception is already being thrown. You can check it while debugging. In VC6, you can catch exceptions under Debug->Exceptions menu. You can select all and stop always. ------------ Ajay Kalra ajaykalra(a)yahoo.com
From: hahoyer on 15 Nov 2005 05:20 The problem is, that this all happens at customers site. In addition it is hard to reproduce. So I still hope that anybody knows, how to deal with this "singularity" in the following sense: How can I customize it, to a) throw an execption instead (since our application provides very good means to observe them) b) add more information on the environemt that created that message Greetings Harald

If you customer is in a different timezone than you I'd take a close look at all of the CTime calls you have. Also, you can change your locale to match the customers and see if you can reproduce the problem then. I've caught lots of problems by tricking my computer into thinking we were somewhere else.
