Re: SearchTextW that returns bounds or itemindex instead of selecting

A release will be later.

Re: Need to send video stream over the internet (RVCamSender, RVCamReciver or smth else?)

I can reproduce the latency on the first connect.
I requires some time to fix, since there is other urgent work now. I'll try to fix it later in this week.

Re: [Demo] Searching with regular expressions

I converted the first demo to Lazarus: https://www.trichview.com/support/files/RegExLaz.zip This conversion is one-to-one, with classes/records mapped to interfaces. I hope I understand it correctly (I assumed that IMatch contains one position defined by GetIndex and GetLength; I do not understand t...

Re: How to analyze document in ReportHelper

If ReportHelper.Richview.ItemCount = 0, it means nothing was loaded. Maybe you did not assign a TRVStyle component to RVReportHelper.RichView.Style? Also, for proper RTF loading, assign ReportHelper.Richview.RTFReadProperties.TextStyleMode := rvrsAddIfNeeded; ReportHelper.Richview.RTFReadProperties....

Re: TRVStyleTemplateCollection : SaveToStreamRVST, LoadFromStreamRVST

It's strange. In 10.2 source, I can see 3 constructors for TMemIniFile, all of them has FileName, not Stream parameter.

Re: is possible usage of richviewEdit in windows service application

How do you want to use it? To display a editing window, or for saving and loading files? I believe, it is not possible to show any GUI from a service. But I believe, you can use TRVReportHelper component to save and load files. Internally, it creates an invisible TRichView window, I think it is poss...

Re: Need to send video stream over the internet (RVCamSender, RVCamReciver or smth else?)

2. Do you use the newest version of RVMedia? In older versions, there was a bug with VideoLatency = 0, it is fixed in the new version. 9. Encoding = *Change uses less traffic. But it requires more CPU usage (mostly on the sender side), because it requires detection of changed areas. And this mode ma...

Re: Need to send video stream over the internet (RVCamSender, RVCamReciver or smth else?)

1. Yes, TRVCamSender and TRVCamReceiver work together. One receiver can receive data from one or more senders. Currently, TRVCamSenders sends all frames received from the camera. When a camera receives a new frame, it calls OnGetImage, and also give this frame to all linked viewers and senders. 2. Y...

Re: [Demo] Searching with regular expressions

Do not use the functions from RVGetText/RVGetTextW. Only the functions from RVLinear provide one-to-one correspondence with the document.
What regexp library do you use?

Re: ScaleRichView 9.0.3 memory leaks and painting issues

Finally, it seems I found a solution for the problem of black scrollbars and panels when TSRichViewEdit is used together with TMS components.
Assign False to SRichViewEdit.DoubleBuffered.
This setting will be default in the next update.

I am sorry for the delay, it is caused by uploading a new version, compatible with Delphi 10.4.
