[lazarus] Getting a svn update while Packages are used - Lazarus undo's the changes.
Hi, I've noticed this a few times now and was wondering if it could be fixed or improved on (and if I should report it as a bug or feature request). In summary, changes to packages get undone while Lazarus is open! Lets use an example to explain. If I have Lazarus open and loaded one of my projects that have required packages list. One of those required packages are fpGUI. I don't actually have the Package open, only the project! Now if I get a svn update for fpGUI while Lazarus is open and the update had changes to the fpGUI changes, Lazarus will overwrite the changes with what's loaded in memory. The Lazarus Editor will detect the changed files and ask if you want to reload it, but when it comes to Packages, Lazarus simply overwrites the package .pas file. This happened again to me today. I did some development work over the weekend at home. I added a new unit to the fpGUI package. Today I got to work, open my project and realized I needed to get a fpGUI update. Got a update, then double clicked in Project Inspector window on one of the required packages, so I can open the fpGUI package, so I can recompile it. Again, the new unit I added didn't appear in the fpGUI package. Did a 'svn diff' and it shows that the package's .pas file was modified and the new unit was removed Very frustrating.

Re: [lazarus] SQLite 3 datetime and timestamp
En/na Luiz Americo Pereira Camara ha escrit: - Try sqlitepass and sqldb/sqlite3. I vaguely remenber of sqlitepass to support timestamp. I don't know about sqldb. Note that sqlitepass is windows only (at least it was last time I looked). You can also use zeos, it is cross platform but I didn't check if/how it does support timestamps with sqlite (since, as Luiz explained, you can put any data type in any sqlite column).

Re: [lazarus] SQLite 3 datetime and timestamp
Hi Luiz,
first of all, thanks a lot for the good job you did with sqlite for us all!
So, now my app can understand a timestamp field as a TDateTime instead
of a string...
..

...
Here's how sqlite works (for good and bad):
- You can create tables with any field type: TIMESTAMP, TIME_STAMP,
QWERTY etc
- In any of this field type you can store anything: a integer, a
float, a string
Many sqlite managers make assumptions (each one create its own
..
[removed]
...
I'm perfectly aware of that and I'm living happily with it...it's an
embedded database anyway!
I don't expect a QWERTY type to be understood, of course, but I
thought a timestamp might, because the sqlite.org documentation
http://www.sqlite.org/lang_createtable.html
refers to it. And SQLiteAdmin and SQLite Manager and SQLite Firefox
extension can understand it.
Anyway, as you said, it is opensource and with a very open license, so
I just added the three lines of code I needed: my post number 1) is
just to share it.
The code needed is only:

begin
AType:= ftMemo;
It's not expensive from the point of view of the code performance nor
lightweight.
Even better, one could also assign AType := ftTimeStamp (which is
alreay defined in db.pas) and then change also db.pas accordingly:

I haven't seen the source code of the tools I mentioned above, but I
guess that sqlite3ds would behave in the same way if you change the
IFs like:
if (ColumnStr = 'TIME')
into
if ( Pos('TIME',ColumnStr) 0 )
which is similar to what you do with BOOL, except that 0 understands
the CURRENT_TIME type that you can find in the documentation of sqlite

Re: [lazarus] SQLite 3 datetime and timestamp
Now, about assumptions. in sqlite3ds there is the assumption that BOOLEAN fields are stored as 1 or 0. In fact, to recover a db that had TRUE and FALSE, I made a new class where I changed ftBool to fString. In this way I could read them, parse them and then write them back as 1 or 0. With the dates, the problem is similar, because sqlite3ds understands that the field is of type DATE, and so it makes the following assumption in customsqliteds.pas line 603: ftFloat,ftDateTime,ftTime,ftDate,ftCurrency: begin Val(StrPas(FieldRow),Double(Buffer^),ValError); Result:= ValError = 0; end; In the database I have, the dates are in the ISO standard form 2007-12-03 12:11:10.1234 How do you suggest me to handle with them ? 1) by complicating the SQL queries with SELECT date(field_name) as field_name FROM... which turns the field_name into a string in the result set 2) by subclassing or anyway changing the TFieldType ? 3) like with boolean, by making a special temporary class that parses the whole database (not so big) and changes the dates into Freepascal-style doubles (are they stored more efficiently ?) 4) other (please specify :-)) My brain-storming last night came up with the idea of adding a flag that says force every field as a string: this would let someone who doesn't know which convention was used in which field to inspect it. Is it somewhat crazy ? By the way, I really like sqlite and the unit you made to access it. When the project I'm working on is finished, I'll strip everything from the source code and only leave a detailed tutorial for using sqlite without visual components. Meanwhile, I read somewhere in the mailing that you are writing a documentation for sqlite3ds; is it ready or partially ready ? I'm studying the whole code at the moment and some documentation would help a lot, especially to see the global structure, to get the large picture of it. Moreover, I'm going to keep on working a lot with sqlite, so if some contribution is needed somewhere, let me know.

[lazarus] Main Form retreiving data from Child Form
Hi All, I have an MDI application in which I have two forms. Form1 (Main form) and form2 (Child Form). In form 2 I have some TComboBox and TEdit Components. In the main form I have some TEdit components. I would like Form1(MainForm) TEditBox to have info from Form2(Child Form) TEditBox. I thought of two ways of doing this and would like to know if there is a better way Method 1. TIniFile. When I close form2 I write to a .ini the contents of form2. Then When I Activate Form1 (OnActivate) I read the info from .ini and fill in the info into the TEdit. Method 2. I use global variables. When I close Form2 I have global variables that store the contents of TEdit from Form2. When I go to Activate form1(OnActivate) I use the global variables and assign to the TEdit in Form1. Please let me know if there is a better way. I do not feel too good about global variables since it is a little scary and not good practise and TIniFiles are a little cubersome. Is there a better way in Lazarus. Thanks Lefti

Re: [lazarus] Main Form retreiving data from Child Form
You can use public variables (or a private variable with the corresponding public methods for reading and writing to it, or even better a property). For simplicity, let's say that we go with the public variables. Let TMainForm be the class name of the main form. In the child form class, you could declare a public variable like: formMainReference : TMainForm and then in the main form you do a: formChild := TFormChild.Create(self); formChild.formMainReference := self; formChild.Show; the in the child form code you can do: formMainReference.editBoxInMainForm.Text := 'hello'; You can also do the other way round, but beware not to free the child before accesing the data. By the way, I never tried it, but did you notice that by creating the child form: formChild := TFormChild.Create(self); you are passing a reference of the calling form ? Any TComponent object has a Owner property, so that formChild.Owner is the main form. You only need to type cast it to a TFormMain in order to use it. .02 R# 2007/12/3, el stamatakos [EMAIL PROTECTED]: Hi All, I have an MDI application in which I have two forms.

Re: [lazarus] Lazarus on Fedora 8
C Western wrote: The switch from Fedora 7 to 8 seems to have revealed some problems. The same lazarus executable looks fine on 7, but on 8 has two issues: 1. The font used for menus and dialog boxes is now a rather larger font (?Arial) and is clearly not using the gtk2 theme settings. I suspect this is because the gtk1 theme info is no longer installed but I can't identify the appropriate files. Any ideas? 2. The font used for displaying source code looks rather worse - it does not show reserved words in bold, for example. Changing the font via the environment options does not seem to help. Has anybody else had this problem? And the answer (for future reference) is that 75dpi fonts needed to be manually installed. The version 7 install had both 75 dpi and 100 dpi fonts automatically, but version 8 (on two different systems) only installed the 100 dpi fonts. The reduced selection seems to have defeated the default gtk1 theme, and given a reduced choice of fonts for LCL.

Re: [lazarus] SQLite 3 datetime and timestamp
Roberto Padovani wrote: Now, about assumptions. in sqlite3ds there is the assumption that BOOLEAN fields are stored as 1 or 0. In fact, to recover a db that had TRUE and FALSE, I made a new class where I changed ftBool to fString. In this way I could read them, parse them and then write them back as 1 or 0. With the dates, the problem is similar, because sqlite3ds understands that the field is of type DATE, and so it makes the following assumption in customsqliteds.pas line 603: ftFloat,ftDateTime,ftTime,ftDate,ftCurrency: begin Val(StrPas(FieldRow),Double(Buffer^),ValError); Result:= ValError = 0; end; True. It stores both in memory and in database the Double value. In the database I have, the dates are in the ISO standard form 2007-12-03 12:11:10.1234 How do you suggest me to handle with them ? 1) by complicating the SQL queries with SELECT date(field_name) as field_name FROM... which turns the field_name into a string in the result set Possible 2) by subclassing or anyway changing the TFieldType ? Difficult 3) like with boolean, by making a special temporary class that parses the whole database (not so big) and changes the dates into Freepascal-style doubles (are they stored more efficiently ?) I already started such tool. Not ready yet. Good if is one step eg you won't access that file every time. 4) other (please specify :-)) Modify the sqlite3ds or create a TSqlite3Dataset descendant that: 1) Recognize a TIMESTAMP field 2) Stores the field value as a string in the desired format 3) When the data is loaded convert from string to double 4) When do ApplyUpdates convert from Double to String I can do that. My brain-storming last night came up with the idea of adding a flag that says force every field as a string: this would let someone who doesn't know which convention was used in which field to inspect it. Is it somewhat crazy ? It's more difficult than above, but possible. By the way, I really like sqlite and the unit you made to access it. Good When the project I'm working on is finished, I'll strip everything from the source code and only leave a detailed tutorial for using sqlite without visual components. Good. Meanwhile, I read somewhere in the mailing that you are writing a documentation for sqlite3ds; is it ready or partially ready ? Partially ready. This is really needed because there's a lot of undocumented features and some feature misuses (like using QuickQuery for execute a SQL) I'll be busy until 15/12. After that i will work on a solution for this case, finish the documentation, work in improvements in sqliteds and release a new sqlite3 wrapper. I'll contact you. I'm studying the whole code at the moment and some documentation would help a lot, especially to see the global structure, to get the large picture of it. Moreover, I'm going to keep on working a lot with sqlite, so if some contribution is needed somewhere, let me know. Fine. The documentation is a place that needs work.

[lazarus] FPC unit in Lazarus
Awhile ago I found that the following 2nd line
(C:\lazarus\fpc\2.2.1\source\rtl\objpas\fmtbcd.pas) causes problems when
using database access units in a dll. (note the space at front of line)
{$r+,q+,s+}
{ $r-,q-,s-}
Removing the space fixes the problem for me, though may cause others yet
unknown.
Question 1 - How would I determine if this has been fixed without
downloading a full snapshot ?.
I can use the WebSvn interface to check Lazarus source, but not the fpc
used by Lazarus (which I am assuming to be different to the current FPC
source - patches etc).
Question 2 - How could I fix this for myself ?
I have the latest svn from FPC, compiled ok - but how do I use this with
Lazarus? - paths etc are all different - and will this negate any Laz
specific patches applied by the Laz developers ?
If this is already covered in a wiki or similar - sorry - please point
me to the link.
