08-30-2007, 13:51 bsardinha Joined on 09-11-2006 Posts 11 Strange behavior with ShowFileConversionDlg Attachment: AskDialog.jpg I'm using LeadTools v14.0. There are two strange things happening with this dialog.  The first is that the dialog will only allow you to select up to 5 files when choosing to Add Files.  If you select more than that, it simply won't add them. The second is that if you allow the dialog to show "Ask" for overwriting, the attached is what the dialog looks like.  The text of the dialog is gibberish. Any ideas?    Report

Also, what is the build number (version info) of LEADTOOLS DLLs you have? Can the problem be shown using one of our demos? If yes, which demo and what are the steps? If it only happens in your code, please put the code in a small test project (not your full application) and send me this test project in a ZIP or RAR file.

09-04-2007, 11:46 bsardinha Joined on 09-11-2006 Posts 11 Re: Strange behavior with ShowFileConversionDlg I do have a higher version already, but we're not using it because in the older version the BitmapXRes returns 1 if the DPI is unknown whereas in the newer version, this funtion returns a default value (I believe it's 150).  I need to know if the DPI is unknown, and if so, the user must perform a calibration to identify the true DPI of the image.  These are medical images so the DPI's vary widely and 150 may be a valid value. Is it possible to use the older version for the main LeadTools control and use the higher version for the dialogs?  Or, in the newer version, is there a way to know if the DPI is unknown?  I would like to upgrade fully for everything, but I need to know if the DPI is unknown.      Report

In the DLL API, this property corresponds to the FILEINFO_NO_RESOLUTION flag. Adnan Ismail LEADTOOLS Technical Support    Report

The file conversion dialog does seem to work well in this version though.    Report

Thanks!! P.S. Are there newer help files that I could download?  The patches I've downloaded include properties that aren't included in the help files I have from v14.0 (including the InfoNoResolution property).    Report
