Re: [Lazarus] Can't create calculated field
Try this:
In the interface part of the form unit insert this prototype into the Private
declarations:
private
{ Private declarations }
Procedure OnCalcFields(DataSet: TDataSet); // insert this
Early in the implementation part insert the event procedure:
Procedure TForm1.OnCalcFields(DataSet: TDataSet);
begin
SQLQuery1.FieldByName('calc').AsBoolean := true;
end;
Then after creating your "f" field:
f.DataSet := SQLQuery1.FieldDefs.Dataset;
SQLQuery1.OnCalcFields:=OnCalcFields; // insert this line
Dealing with events without using the Object Inspector can be tricky!

[Lazarus] Tdbf replacement (Windows and Linux only)
Tdbf has been decremented because it is no longer maintained. Advantage TDataSet Descendent is a more powerful and flexible dbase format alternative. It accommodates Foxpro cdx as well as Clipper ntx memo and index file types. You can also use their proprietary Paradox-like format, it will be familiar to those who have used the Delphi BDE. The Local Server version is free, and some or all files can be on the network. You only need to buy the Client-Server version if you have large files and want only the relevant records to travel the network. I have used ADS for years - it is rock-solid, a joy to use, and continues to be maintained. It doesn't support Laz version 1.0.8 yet, you need to use 1.0.6 or earlier now.

[Lazarus] Delphi incompatibility - hard cast
In Delphi this will work even if the Sender is not a TdbGrid, as long as it has a DataSource property: TdbGrid(Sender).datasource:=myDataSource; But it won't work in Lazarus if Sender is a different dbAware component., the compiler will complain it's not a dbGrid.

Re: [Lazarus] Delphi incompatibility - hard cast
OK, how about a compiler switch (that can be turned on or off) that SEARCHES for the property (or event if defined in code and not by the Object Inspector)? It shouldn't be so difficult to deal with Sender (or components in a loop) where the exact Type is not known in advance, just the presence of a specific property or Event. If the switch can be turned Off again after the routine, the impact on performance shouldn't be a concern. Greater flexibility and ease of use, especially for newbies (RTTI is difficult and poorly documented) is needed if freepascal/Lazarus is to become universally adopted. Can there please be a discussion on this? Thanks! A. G.

Re: [Lazarus] Delphi incompatibility - hard cast
Is there also a way of setting an event such as OnEnter for Sender or a Component in a loop (if the Event is defined in code and not with the Object Inspector)? Thank you. A. G.

You just need to understand what you are doing, and use SetObjectProp(Sender,'Datasource',MyDataSource); that's all there is to it.

[Lazarus] clicking a dbgrid's column title does not trigger OnEnter event as with Delphi
It does in Delphi! I have Laz 1.0.4 for Win7 64 bit. Has this been fixed in a later version? Or is there some reason this is different from Delphi? A. G. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
Re: [Lazarus] clicking a dbgrid's column title does not trigger OnEnter event as with Delphi
I clicked on another component first to be sure the grid didn't have focus. OnEnter IS triggered by clicking on a grid cell, but not column header. Same for ActiveControl, which will break some code.

Re: [Lazarus] clicking a dbgrid's column title does not trigger OnEnter event as with Delphi
Why is there no interest in fixing this bug? There is a lot of code transferred from Delphi, and if you don't click on a column title during testing you won't know anything is wrong until a client screams at you. Sure, you can fix it with a SetFocus in the OnTitleClick event of the grid, but why should you have to remember? PLEASE fix in RC3! Thanks. A. G.

[Lazarus] LazReport - access violation
I am using Laz 1.2 for Win32, with Advantage (http://devzone.advantagedatabase.com) for the database, Foxpro CDX format. Everything seems to go ok designing a report with LazReport until I include a memo field, then it crashes. Is there something special I have to do in LazReport to use a Foxpro style memo field?

Re: [Lazarus] LazReport - access violation
UPDATE This only seems to happen when some records have a large entry in the memo field. The problem seems to be with the routine that calculates the field size but I don't know how to fix it.

[Lazarus] LazReport - Group bands
I only wanted a list of unique entries for a key field. So I selected the Group Header band and for Condition selected that key field. I then inserted a Rectangular Object on the band and for dbfField selected the same key field. But Preview showed only a blank page. What else do I have to do?
