Unhandled exception while fitting peaks with the latest NET 9.0 versions of PDIndexer

[loictoraille]

Dear Seto-san,

I happily report a new issue that has been bothering me with the latest versions of PDIndexer. This problem does not exist with v4.446, which means I don't know if it comes from the corrections performed on the decimal separator, or if it comes from the update to the 9.0 NET version.

Here is the problem: when using FormFitting, each time I tick or untick a peak to include or remove it from the fit, I get a popup with the following text (mainly in French, which to me means that it is produced by the NET framework):

If I click on 'Continuer', the rest of PDIndexer works perfectly. This means that it does not prevent me from using the form fitting of PDIndexer, it is just really annoying to have to click on a popup every time I add or remove a peak to the fitting list.

Here is what appears if I click on 'Détails' :

System.NullReferenceException: Object reference not set to an instance of an object.
at System.Windows.Forms.DataGridViewCell.OnMouseUpInternal(DataGridViewCellMouseEventArgs e)
at System.Windows.Forms.DataGridView.OnCellMouseUp(DataGridViewCellMouseEventArgs e)
at System.Windows.Forms.DataGridView.OnMouseUp(MouseEventArgs e)

at System.Windows.Forms.Control.WndProc(Message& m)
at System.Windows.Forms.NativeWindow.Callback(HWND hWnd, MessageId msg, WPARAM wparam, LPARAM lparam)

I've tried installing v4450 with NET 9.0 on a different computer, the same error pops up. I've tried reinstalling (and cleaning the AppData folder), it does not resolve the issue.

ChatGPT suggests me to add the following line somewhere:

if (e == null || dataGridView.Rows[e.RowIndex].Cells[e.ColumnIndex].Value == null)
return;

I hope you will be able to solve this issue easily :) Let me know if you need more information. My PC environment is still Windows 10.

Thanks again for your work!

Best regards,

Dear loictoraille-san,

Thank you for reporting the bug. I apologize for any inconvenience caused.

The bug does not occur in my environment (Win11 24H2). If the .Net version is the same (even if the Win version is different), the software should behave exactly the same, so this is strange.

For now, I have fixed the code that seemed to be related to the bug and released a new version (ver 4.451) .
I hope this will resolve the issue.

Hi Seto-san,

Thank you for looking into it. I've tried with ver 4.451, same problem. I've tried on a windows 11 22H2 computer (with NET 9.0), same problem. I've tried with both settings for the decimal separator (in case the problem was coming from there, since I have the problem but you haven't), same problem.

As usual with my bugs, there is something weird going on and it's annoying since you cannot reproduce it so it's hard to test! Maybe it's still linked to the regional settings somehow?

Do you have any ideas?

[seto77]

Hmm, that's strange. I tried changing the language settings on my PC to French, but no errors occurred.

Could you send me the file that loictoraille-san is working on? (I don't think there's any problem, but just to be sure.)

[loictoraille]

Sorry for the delay.
I add an example file, taken with a 0.3738 wavelength (there is a mix of bcc, and two fcc phases).

Let me know if you have any ideas.
