Re: Mouse wheel scroll does not work in Win7

If dwMajorVersion = 6, this means that your application is not marked as Win10-compatible. I thought that the difference in mouse wheel processing in applications compiled in 10.1 and 10.2 is because they are marked as Win10-compatible (in their manifest). Currently, I have no other ideas. If you do...

Re: ZoomPanel does not repaint when using DevEx Skin

Sorry for the delay. Yes, a zooming panel is drawn using BackgroundProperty's gradient colors (even when a gradient fill is turned off, it is drawn using ColorBegin). So your changes are correct. However, for some skins results are not the best, because a zooming panel uses system (or VCL theme) col...

Re: Mouse wheel scroll does not work in Win7

Make sure that you completely recompiled your application (Project | Build All Project). If the problem still persists, I ask you to do some tests. The first of them. Please open SclRView.pas, find TSRichViewEdit.DoMouseWheel. It must be: function TSRichViewEdit.DoMouseWheel(Shift: TShiftState; Whee...

Re: Problem with importing docx and doc

1) I do not know why. No, the converters specification states that file names must be in OEM.
2) I recommend not changing file system options, but simply writing a code in your application that copies the specified file to a temporal location under a simple name, loading this copy, deleting this copy.

Re: Excel PDF

Report Workshop generates reports in our editor, so this is a question of exporting documents from our editor to PDF. Unfortunately, we do not our own solutions for PDF, but you can use third-party components, both freeware and commercial. See http://www.trichview.com/forums/viewtopic.php?f=2&t=8852...

Re: Load RVF with footer and save to RTF

1) You create three RVStyles, but assign the same RVStyle (FRichStyle) to all 3 controls. Assign different RVStyles, and the main problem will be fixed. 2) Assign the same RVFOptions to FRichViewHeader and FRichViewFooter, otherwise RTF will have incorrect formatting in headers and footers. 3) Optio...

Re: Problem with importing docx and doc

AFAIK, NTFS always supports short file names, but their creation for new files may be enabled or disabled. You can check using the system command line utility fsutil: fsutil behavior query disable8dot3 c: It displays the value for the specified drive (c:): 0 - short file names are created, 1 - short...

Re: Problem with importing docx and doc

Well, probably I should add it to RVOfficeConverter...

However, as I said, it does not help on my computer (Win10, NTFS): it simply returns sLongName.
But at least it does no harm.
