wxDateTime and date validation

[Tim Burgess]

Hi,

 

I have some code that stores a date generated from a wxDatePicker in ISO format:

 

datePicker->GetValue().FormatISODate()

 

Example result:

 

2020-01-01

 

However, I’m failing to retrieve this stored value in a form that I can use to set the value of the wxDatePicker. Here’s my code:

 

wxString temp = “2020-01-01

”;

wxDateTime myDate.ParseISODate(temp);

 

In this example, myDate takes the value wxInvalidDateTime.

 

My project requires that I store the date in ISO format and I assume I’m missing something simple.

 

Any and all suggestions would be most welcome.

 

Best wishes.

 

Tim

Did you try with the following code?

wxString temp = “2020-01-01”;
wxDateTime myDate;

myDate.ParseISODate(temp);

It works on my side ... please see the attached image.
I suspect your problem is due to other than wx itself

Is the code executed in an application (EXE) or in a library (DLL)?

Hi,

I can confirm this works as expected with wxWidgets 3.2.8 and GIT Master on Windows, tested with

 const wxString isoDateSrcStr("2020-01-01");
 wxDateTime dt;

 if ( dt.ParseDate(isoDateSrcStr) )
 {
     wxString isoDateDstStr = dt.FormatISODate();

     if ( isoDateDstStr == isoDateSrcStr )
         wxLogMessage("ISO date roundtrip successful: %s", isoDateDstStr);
     else
         wxLogError("ISO date roundtrip unsuccessful: %s vs %s", isoDateSrcStr, isoDateDstStr);
 }
 else
     wxLogError("Could not parse ISO date %s", isoDateSrcStr);

I have also checked whether it matters if the datetime was valid (had value) before parsing: It does not.

Best,
PB

Ooops, I had a typo in the code in my previous post, using ParseDate() instead of ParseISODate(). 

The conclusion still stands though, full corrected code:

        const wxString isoDateSrcStr("2020-01-01");
       

wxDateTime dt;

        if ( dt.ParseISODate(isoDateSrcStr) )
