CDate function using different locales

问题

I am using QTP (therefore VBScript) and I seem to have a problem with the CDate function.

When my colleague in Malaysia is using it there is not a problem. When I use it here in Spain I have the following error.

Now all I am asking is if there are any known issues with this function or any other related ones like FormatDateTime between different locales.

Anybody knows this?

Thanks in advance.

The error specifies the problem. todateObject.GetROProperty("value") contains a value that CDate does not recognize as a date.

You will need to first determine what is being returned by todateObject.GetROProperty("value"), and then make sure it can be converted to a date.

You may want to consider creating the date using DateSerial instead of CDate to avoid problems arising from cultural differences. If that is the case, depending on your circumstance you may need to provide separate fields for Day, Month, and Year to assure the order is always correct.

CDate() tries to convert its input to a date, taking the Locale Setting into account. See:

>> SetLocale "en-us"
>> WScript.Echo GetLocale()
>> WScript.Echo 1, CDate("1 dec 2011")
>> WScript.Echo 2, CDate("1 dez 2011")
>>
1033
1 01.12.2011
Error Number:       13
Error Description:  Type mismatch
>> SetLocale "de"
>> WScript.Echo GetLocale()
>> WScript.Echo 3, CDate("1 dez 2011")
>> WScript.Echo 4, CDate("1 dec 2011")
>>
1031
3 01.12.2011
Error Number:       13
Error Description:  Type mismatch
>>

CDate() under "en-us" understands "dec", but chokes on "dez"; "de" works with "dez", but not with "dec".

A minimal impact strategy to solve your problem could be to enforce 'one locale for all' by using SetLocale() and some big stick (input validation) against sloppy data entry persons.
