Using Shockwave Flash as OCX control in Win32 app.

Question

I program in Delphi. On my development machine I have imported the Flash10h.ocx control and have developed a Win32 application which will render a swf file. This all works fine on my development machine.

However, I am trying to get the same application to work on another box. I have installed Flash for Internet Explorer; I can go to sites and it will place Flash. But for some reason or another my Win32 application will not play the swf file.

One thing I have noticed is that on my development computer I have the following files in the C:\Windows\System32\Macromed\Flash folder:

    Flash10h.ocx
    FlashInstall.log
    flashplayer.xpt
    FlashUtil10h_ActiveX.dll
    FlashUtil10h_ActiveX.exe
    FlashUtil10h_Plugin.exe
    install.log
    NPSWF32.dll

On the computer having problems I have the following:

    Flash10i.ocx
    FlashInstall.log
    flashplayer.xpt
    FlashUtil10h_Plugin.exe
    FlashUtil10i_ActiveX.dll
    FlashUtil10i_ActiveX.exe
    NPSWF32.dll

Any ideas why the Win32 app. is not playing the Flash Files?

Answer 1

It looks to me like a version mismatch. In your first list, look at the letter following the version number for both FlashUtil10_ActiveX.exe and FlashUtil10_Plugin.exe. On the working system, both files have = 'h', which matches FlashUtil10h_ActiveX.dll; on the problem system, the FlashUtil10h_Plugin.exe doesn't match the = "i" versions of FlashUtil10i_ActiveX.dll and .exe.

IOW, the parts just before the underscore in the filenames is a version number. On the good machine, all the version numbers match at 10*h*; on the bad machine, one file has version 10*h*, the other two are at version 10*i*.
