Problem creating channel property in tdm file

[Kuo]

Hi, Stefan:

Here it is:

static const char * FILE_Property_Test = "File Property Test";

Argument "file" is the DDCFileHandle

Hi Kuo

blanks are not supprted in property names.

Property names should only contain alpha numerical characters.

The following poperty names are resevered and may not be used on channel level:

Well if that is the case then the LabVIEW TDMS vis should not allow the use of spaces in property names.  

[YongqingYe]

TDMS does support white space in property names an property values. TDMS and TDM are different file formats.

[StefanR]

Note: Other software than LabVIEW such as DIAdem or DataFinder cannot deal with e.g. spaces in property names and will replace 'forbidden' characters with '_'.

[Kuo]

That's true. So far I used DIAdem fairly well.
