Hi,


Anybody here have an idea why the LoadRVF sometimes returns false? What are the factors that affects this? I've been trying to load a file which was being saved using SaveRVF..

Thanks in advance..

One of the most possible reasons:
- document includes unregistered graphic class or control; TBitmap, TIcon, TMetafile and TJPEGImage do not need to be registered; for other graphic classes, as well as for all components inserted in the document, call RegisterClass, one time, before the first loading:
RegisterClass(TButton);
RegisterClass(TGifImage)
- styles are not saved in RVF and changed after saving:
* make sure each TRichViewEdit is linked to its own TRVStyle
* right click at TRichViewEdit at design time, choose Settings in the popup menu, make sure that "Allow adding styles dynamically" is set;

Thank you so much sir for the reply..

Actually, my RichViewEdit is created at runtime & has its own style, could you pls check if the ff. options are fine during creation?:

-------------------------------------------------------
Options := [rvoAllowSelection, rvoScrollToEnd, rvoClientTextWidth, rvoShowPageBreaks,
rvoTagsArePChars, rvoAutoCopyText, rvoAutoCopyUnicodeText, rvoAutoCopyRVF, rvoAutoCopyImage,
rvoAutoCopyRTF, rvoFormatInvalidate, rvoDblClickSelectsWord, rvoRClickDeselects];
RTFOptions := [rvrtfSaveEMFAsWMF, rvrtfSaveJpegAsJpeg];
RTFReadProperties.UnicodeMode := rvruMixed;
RTFReadProperties.TextStyleMode := rvrsAddIfNeeded;
RTFReadProperties.ParaStyleMode := rvrsAddIfNeeded;
RVFOptions := [rvfoSavePicturesBody, rvfoSaveBinary, rvfoSaveControlsBody, rvfoSaveBack,
rvfoLoadBack, rvfoSaveTextStyles, rvfoSaveParaStyles, rvfoSaveLayout, rvfoLoadLayout, rvfoSaveDocProperties,
rvfoLoadDocProperties];
-------------------------------------------------------

Based on what you've said about RegisterClasses, i'm doubting now my custom classes that will be inserted in the RichViewEdit, the RegisterClasses are in its own individual unit's Initialization.. Example:

-------------------------------------------------------
TCustomClass1 = class(TPanel)
private
...
...
end
...

initialization
RegisterClasses([TCustomClass1]);
end;
-------------------------------------------------------

Does this mean that i should transfer this to the unit in the Initialization section of the unit where the RichViewEdit is created? And should I include all the used classes (whether custom or not) inside that unit?


Thanks again in advance sir..

It does not matter where you call RegisterClasses.
Calling them in your unit is ok.

PS: if your panel contains other components, they must be registered as well.

Only visual components must be registered right?

No, any component that can be stored in RVF.

Thank you so much for your help sir..
