Animate does not function after OpenFileDialog!?

[Alexander Holzer]

Hello,
I stated that Animate_Open/_Play without function after OpenFileDialog call.

Try PBwin-example "Animate.bas" edit:

...
[COLOR="Red"]#INCLUDE "ComDlg32.inc"[/COLOR]
...

FUNCTION PBMAIN () AS LONG

    LOCAL hDlg AS DWORD

[COLOR="Red"]local f as string
local lstyle as long

f = "*.txt"
lstyle = %ofn_filemustexist or %ofn_hidereadonly or %ofn_longnames
openfiledialog(0, "open file", f, "c:\", _
"text files|*.txt|all files|*.*", "txt", lstyle)[/COLOR]

    InitComCtl32(%ICC_ANIMATE_CLASS)

    DIALOG NEW 0, "Animation demo",,, 185, 60, %WS_CAPTION OR %WS_SYSMENU, _
...

and open you any for TXT file. Now try to start animation.
Idea?

Thanks.

Apparently there is a memory or Z-order conflict if you try to run the open file dialog before the animate control is operational. You should send this to [email protected].

If you place the open file code into the callback in the %WM_INITDIALOG case after this line:

Animate_Open hAnimate, "FILECOPY.AVI"

Then it will work.

Thank you Richard.
In the example - yes ,but in the correct program it will implement with difficulty.

[Richard Angell]

In your program, code unseen here yet, it appears the openfile call should still come after the animate control has been loaded and a file provided to it ...

What version of PBWin are you using?

PBWin 9.0
The mistake or disputed situation with OpenFileDialog and Animate_Open/_Play exist. Also it is the fact.

Which OS version are you using?

[Steve Rossell]

The OpenFileDialog API call is changing the current directory when selecting a file. Therefore the

Animate_Open hAnimate, "FILECOPY.AVI"

cannot locate the file "FILECOPY.AVI". You can use the style bit of %OFN_NOCHANGEDIR and the API will keep the current directory the same or use the full path to the AVI filename.

Thanks Steve!
Now everything is clear.

From MSDN Library:

OFN_NOCHANGEDIR
Restores the current directory to its original value if the user changed the directory while searching for files.

Windows NT 4.0/2000/XP: This flag is ineffective for GetOpenFileName.

Bruce,
Where is that??? I am curious if its when user hits "Search", and then in another window goes to check something else???

Or if it holds the last known folder? (and maybe better than some other techniques)

[Rodney Hicks]

Where is that???

What?
If you mean %OFN_NOCHANGEDIR it is in the help file under 'flags' in the DISPLAY OPENFILE page.

Try this on XP SP2 or SP3, then see if you believe MS that the %OFN_NOCHANGEDIR flag has no effect in XP

#COMPILE EXE

    LOCAL PFN$,olddir$
    olddir$ = CURDIR$
    ? "Change to a different directory and select any file,each time."

                    "*.*", "", %OFN_ENABLESIZING OR _

      "IS  directory:  "+ CURDIR$ + $CRLF + $CRLF + "file selected:  "+ PFN$,, "omit %OFN_NOCHANGEDIR"
    
    CHDIR olddir$  'back to square one

    DISPLAY OPENFILE 0, , , "",CURDIR$ , "", _
                    "*.*", "", %OFN_ENABLESIZING OR _
                    %OFN_FILEMUSTEXIST OR %OFN_PATHMUSTEXIST OR _
                    %OFN_EXPLORER OR %OFN_NOCHANGEDIR TO PFN$

    ? "WAS directory: "+ olddir$ + $CRLF + _
      "IS  directory:  "+ CURDIR$ + $CRLF + $CRLF + "file selected:  "+ PFN$,,"with %OFN_NOCHANGEDIR results"
END FUNCTION

on this XP system it does!
