hi all, I'm not the only one to experience the error "StringToNumber". I've seen it in other posts for e.g. QR emulator. Another collegue has the same issue, since we migrated from XP to 7. Do you have a solution now ? What do you try to convert at the start up of the program ? Is is the definition file version that is corrupted (I installed version 1.1.10.0)? Windows is localized in French; Also, in the registry for dvtp extensions (HKLM/SW/classes/DVT project file/shell/open I have 2 entries : Default "C:\Program Files (x86)\DVTk\DVT\Bin\DVT.exe" "%1" command ~Z^2_c'M0@q`brF(Ec`!>o^FG0sv9pg`E,B7W3~be "%1" The "command" one seems weird... Is there a unicode issue ? C:\Program Files (x86)\DVTk\DVT\Bin\DVT.exe Error type: System.FormatException Error description: Le format de la chaîne d'entrée est incorrect.

Sorry, it should be more readable with line breaks.

LS,

recently, I was able to help a DVTk user with the same problem.

It took me some time to figure out a workaround:
Change the formats (found under the "Region and Language" settings of windows) fom French to English. That will do the trick for now for your current version of your DVTk applications that use definition files. This never came out of our tests as we are developing and testing on English windows versions.

This should however still be solved in new versions of our software (a language format indepent conversion should be used), so I created a ticket for this on this web site.

Regards,
Marco

I've had this problem with DICOM Compare, I'll try the fix and hope that it works. (I'm running Windows with English language but Swedish formats).

It worked, thanks!
