In designer LayoutControl ` and (the form is inherited from standard designer TdxLayoutControlCustomizeForm) it is necessary for the selected elements to assign any label, for example, in Tag to write down 1 either 0. Or to one to an element.
As and not in the designer, and directly in LayoutControl ` windows where this lives dxLayoutControl too it is necessary to walk on selected or on all and to understand, what selected and what is not present.
The main thing - to receive the list of the selected elements that in a cycle on SelectedItems to specify to any member property the necessary value.
As a result, that at window discovery such elements, at which tag = 1 have been hidden.
I.e. the user in program adjustments includes certain and at window discovery such elements need to be hidden.

Operation with a sound a sine curve, timbre and loudness change (on the fly)
Colleagues, hello!
Who in a subject, help...
The task - continuously to generate a sound (a pure sine curve), but only to change its tonality and loudness, as they say to "touch".
Found the code: http://www.delphitricks.com/source-code
_card.html
All is good, yes there is a pause between calls, and a pause notable. And it is necessary that instantly frequency and loudness it was possible to change.
procedure Tfmain. Button3Click (Sender: TObject);
var
a: integer;
begin
for a: = 1 to 5 do
begin
MakeSound (1100, 300, 50);//<<<between "units" a pause ~0.3 (((
MakeSound (1100, 300, 50);
MakeSound (1100, 300, 50);
end;
end;As an output to drive a signal not , and to modulate it "on the move" as it is necessary. Whether Here only it is possible to prompt, in what direction to dig to me...
I think it is necessary to place the code by the link in a separate flow, and to influence a flow in a flow. Only under the task - task runtime on tonality and loudness change 1 seconds and that at all there were no empty pauses.
Links to examples are welcomed.

ADOQuery and dates
Children all greetings!
At me it is filled StringGrid, here there are two columns "Date with" and "Date on". Further I collect SQL request and through ADOQuery I send it on performance. But faced here such problem - if dates are read with StrigGrida the request returns nothing. If I register dates in the code the request returns the data. Dates identical.
ADOQuery1.Parameters. ParamByName (' DateFrom ').DataType: = ftDate;//we Assign type
ADOQuery1.Parameters. ParamByName (' DateTo ').DataType: = ftDate;
//Here so the request returns nothing!!!
ADOQuery1.Parameters. ParamByName (' DateFrom ').Value: = StrToDate (Cells [4, i]);
ADOQuery1.Parameters. ParamByName (' DateTo ').Value: = StrToDate (Cells [5, i]);
//And here so the request returns the data
ADOQuery1.Parameters. ParamByName (' DateFrom ').Value: = StrToDate (' 10/1/2016 ');
ADOQuery1.Parameters. ParamByName (' DateTo ').Value: = StrToDate (' 10/27/2016 ');At once there is a thought that in most StrigGrid the wrong information is stored. But I checked, there the same dates (line).
The conversion problem to date through StrToDate when I take value from StrigGrid can?

DevExpress the filter on entrance %LIKE % in ColumnPopup

Questions on operation with flows
All kind day!
Never before with flows worked, therefore there is a pair of questions... There is a flow which does the same operation on time.
Pulls out the data from DB Firebird and saves in a file of Eksel. Costs FreeOnTerminate: = true, that is I launch it, further it is not necessary to me.
In this connection a question:
1) At program termination, I somehow should complete forcedly a flow if suddenly it works at present? Or Delfi the automatic machine kills him at an output?
2) Found that in a flow it is necessary to create the copy of session for a connection to basis... Whether Really it is necessary? Now works and so

To calculate probability of an outcome of a batch
Children, help , and that with mathematical apparatus not so.
There are two chess players with rating : https://ru.wikipedia.org/wiki/_
As I understood, for calculation of rating Gaussian distribution (normal distribution) is used.
looks so: A - the Difference of ratings. In - Expected result for the player with higher rating. About Expected result for the player with lower rating
AND IN WITH
0 0,5 0,5
25 0,53 0,47
50 0,57 0,43
100 0,64 0,36
Etc.
In chess three results (a victory white, a drawn game, a victory black) are possible.
Let's admit, at player A a rating X, and at player B rating Y.
How to calculate probability of victory A, probability of victory B and probability of a drawn game? Under what formulas?

FireDac does not understand the coding in FTS to the table of basis SQLITE.
There is basis SQLITE with Encoding=UTF8.
I read from basis by means of AnyDac (FireDac) in Delphi XE3 with ADQUERY and with ADTABLE.
When there is a normal table
CREATE TABLE table0 (mytext Ntext, publishdate date);
INSERT INTO (mytext, publishdate) VALUES (' greetings ', ' 1998-12-07 ')
All is normal - ADQUERY with ADTABLE return mytext =''
And at creation FTS of the table
CREATE VIRTUAL TABLE table0 USING FTS4 (mytext, publishdate);
INSERT INTO (mytext, publishdate) VALUES (' greetings ', ' 1998-12-07 ')
At reading instead of ' greetings ' are had '?????? ', i.e. in this case FireDAC reads this data as ANSISTRING.
NTEXT, NVARCHAR near to mytext at table creation do not help.
In basis it is written down truly - ' greetings ' (opened basis with SQLITEEXPERT).
What it is necessary to make, that and in the second case FireDAC returned in the correct coding?
(SQLQuery from dbExpress in DelphiXE3 returns ' greetings ')

Dialogue forms FastReport
Hello!
In FastReport there are the Dialogue forms intended for input and parameter passing in the report.
The dialogue form is shown before report start.
It would be desirable to allocate the Dialogue form on the report that the user filled with the data, pushed Raschitat and the report was constructed. Changed one parameter (instead of entered all of them anew), pushed Raschitat and received the new report.
Prompt, as such to implement!
