Wrappers for Delphi 2010

[jeffp]

I'm in the process of porting my code from Delphi 2007 to Delphi 2010 and have encountered some issues relating to your Delphi wrappers.

As of Delphi 2009, Delphi supports Unicode and in doing so they changed some of the types. The big change is that PChar is now mapped to PWideChar where it used to be mapped to PAnsiChar.

I discovered this when I put your code in Delphi 2010 and kept getting the demo watermarks on all my PDF. I found out that the cause of this was because your procedures that relate to the RegKey and DevCodes in your Delphi wrappers use PChar. So in 2007 that meant PAnsiChar but in 2010 in meant PWideChar, which caused in not to work in D2010.

I got it working by changing all the PChar in your Delphi wrappers to AnsiString.

I'm not sure if this will mess other procedures up but it does seem to work with the procedures that require the RegKey and DevCode.

Do you have updated Delphi wrappers that have been tested on both D2007 and D2010 (I didn't see any in your latest SDK builds)? If not, you might want to look into this issue.

Hi Jeff,

will try and get these available tomorrow if possible and will advise when ready.

please nudge me by a repost if you have not heard by lunchtime ..

Don't hurry on my account since I've got something working for now. I just know this will come up as more Delphi developers move to D2010 and beyond and have to deal with the Unicode headaches that I've been though this week.

Again, in converting yours and other Delphi wrappers around windows DLLs, the best solution seems to be to change PChar type to AnsiString and then it works for all versions of Delphi.

Hi Jeff,

the strange thing is - apparently we have these and use them ourselves for various tools (C#, DOTNET, Delphi etc) for creating our own examples - but no one ever told me and we have never distributed - we will be doing so in the very near future now I know with the SDK's by default

[jeffp]

Maybe the conversion is PChar to PAnsiChar instead of AnsiString.

Attached is an article widely cited on the changes in Delphi 2010. Your dev guys will understand all this much better than I.

Let me know when you have the new wrappers done and I'll test them out for you on both versions of Delphi.
