Compatibility issues between FastReport 3 and FastReport 4:
|
|
|
|
- v4 uses the same file/package names as v3. You have to uninstall v3 before
|
|
installing v4.
|
|
|
|
- v4 uses the same file format, .fr3 and can open v3 files without any problems.
|
|
Most of new report files also can be opened by v3, but not all.
|
|
|
|
- v4 can read v3 .fp3 files.
|
|
|
|
- New kind of page, "Data" page is introduced in v4. This page contains all
|
|
internal datasets of your report. When opening old v3 files, v4 automatically
|
|
adds the "Data" page and moves all datasets on it.
|
|
|
|
- Since all v4 reports contain a "Data" page, you should check your Delphi
|
|
code where you access a report page by index. The "Data" page is always the
|
|
first one. So code like Page := frxReport1.Pages[0] will return a data page.
|
|
You should correct that code (either use [1] or access a page by its name).
|
|
|
|
- Check your reports that contain the Cross-tab object!
|
|
a) In v4, this object draws cross-tab elements in design-time
|
|
and is bigger than in v3. So you have to correct bands that contain
|
|
such object.
|
|
b) New behavior introduced in v4 - table can have corner, title, cell headers.
|
|
All these properties are on by default. You may turn off corner and title
|
|
(ShowCorner, ShowTitle properties) if not needed, and fill in the cell
|
|
headers elements.
|
|
c) In v4, table has several cell elements. Each cell element has its own
|
|
font/color/frame/... settings. In v3 you were able to setup only one cell
|
|
element. You should set the fonts and colors for each new element, if needed.
|
|
|
|
- frxHiButtons unit is no longer used - remove it from your "uses" list
