Re: Installation problem
Do you use Starter edition of Delphi? This edition does not include command line compilers. The only way to install TRichView in Starter edition is opening packages in IDE one by one and compiling/installing them. Normally, the installer creates packages in default location specified in RAD Studio. ...

Re: [Demo] Sending HTML email. Saving MIME-encoded files.
The demos were updated for compatibility with TRichView 17.3. Now they use functions included in TRVGraphicHandler class, so the code is slightly simplified. The demos include a newer version of DMime (2.8). It is compatible with RAD Studio 10.2 Tokyo. DMime is used to implement base64 encoding in D...

Re: Fastest way to search for text in RVF files?
There are no functions for searching text in RVF files, sorry. You need to load them one by one. The slowest procedure is formatting, and SearchText method requires a formatted document. So, if you need a fast search, avoid using SearchText, and create your own procedure for searching text in TRichV...

Re: fault : Add Tcheckbox cause slow
I am afraid if you add many controls, they will slow down scrolling, and it is unavoidable.
(unless you use ScaleRichView, which displays images of controls instead of controls themselves)

Re: time passed until first typed letter appeared in memo.
You use TDBRichViewEdit. It does some work when the table is moved to an editng state (it stores the field content in a stream, to check later, if it was really changed). The editor moves database into editing state when you type a character or call any editing method (such as InsertText). So, when ...

Re: find word in text and swap by value coming from database
Sorry, I do not understand the question. Can you explain with more details, what do you want to implement?
Which code did you take as a base? Not all field merging demo projects use item tags.

Re: time passed until first typed letter appeared in memo.
I still do not understand why it may happen. Are these image resized? Also, I which graphic classe is used for them? May be you send me RVF file containing some reasonable count of images, I'll multiply them for testing. And this delay may be caused by your code in events, what's why I ask about rep...

Re: [Example] Removing formatting
This code is for TRichView 17.3 and newer. No Unicode<->ANSI conversion is needed any more, because all text is Unicode. procedure RemoveFormatting(RVData: TCustomRVData; RemoveMarkers, KeepLinks: Boolean); var i, HypertextStyleNo: Integer; {.............................................................

Re: time passed until first typed letter appeared in memo.
Does the same problem happen in ActionTest project, or only in your project? Unfortunately, there are no function that return the amount of memory used by the editor. The editor allocates many objects, and nobody calculates their total size. Moreover, because of image caching, the amount of allocate...

Re: RVMedia 5.0
Unfortunately no, this function is not implemented.
PS: if you have some other, more sophisticated motion detection library, you can use RVMedia's TRVCamera to get video frames and this library to process them.

Re: time passed until first typed letter appeared in memo.
For testing, try to increase side of image cache.
Add in DPR file, before creating any form:
uses RVGrCache;
RichViewMaxPictureCount := 10000; // set value greater than the count of pictures in your document
