Indy 10.6.2 works with Delphi 6 and can be downloaded here:
https://github.com/IndySockets/Indy <== Downloaded the package from here
Hi
I tried to install Indy 10.6.2 into Delphi 6.
First I would need to recompile the CompUtils.dpr under delphi 6 running in Windows XP as i think the CompUtils.exe is not meant for Win XP.
After compiling that into CompUtils.exe, i run the fulld_6.bat in terminal mode
Once that has been done,
Open the Delphi 6 and compile the package IndyCore60.dpk. When i tried to install it, it prompted me "Cannot load package IndySystem60. It contains unit IdWinSock2 which is also contained in Package Indy60."
Then i recompile and install dclIndyCore60.dpk and it came out the same message. "Cannot load package IndySystem60. It contains unit IdWinSock2 which is also contained in package Indy60
Then i recompile and install IndySystem60.dpk and another message "Cannot load IndySystem60. It contains unit IdGlobal which is also contained in package Indy60.
Where is Indy60 package?
I tried to look for it but cant find it.
please advise

hi
attached is the code whereby it generated the error.
The funny thing is that this app can run on other machines without error but only that particular machine.
procedure TDataModule1.loadFilterTable;
var
l_str : string;
l_ini : TIniFileEx;
l_fieldList : string;
begin
if (trim(FFilterDay) = '') and (Trim(FFilterOthers) = '') then
l_str := ''
else if (Trim(FFilterDay) = '') and (Trim(FFilterOthers) <> '') then
l_str := Trim(FFilterOthers)
else if (Trim(FFilterDay) <> '') and (Trim(FFilterOthers) = '') then
l_str := Trim(FFilterDay)
else
l_str := Trim(FFilterDay) + ' and ' + Trim(FFilterOthers);
cdsDYNAFLTS.Close;
qyDYNAFLTS.Close;

l_Ini := TIniFileEx.create(ChangeFileExt(Application.ExeName, '.ini'));
l_fieldList := l_ini.ReadString(DYNAFLTS_TABLE, INI_SECT_FIELDS, '');
// cc : if the field list is still empty, then make it a *
if Trim(l_fieldList) = '' then
l_fieldList := '*';
l_ini.Free;
qyDYNAFLTS.SQL.Add('SELECT ' + l_fieldList + ' FROM ' + DYNAFLTS_TABLE );
if l_str <> '' then
qyDYNAFLTS.SQL.Add(' WHERE ' + l_str);
DoLog('LoadTableData2 SQL: ' + qyDYNAFLTS.SQL.Text);
cdsDYNAFLTS.ProviderName := '';
cdsDYNAFLTS.ProviderName := 'dspDYNAFLTS';
cdsDYNAFLTS.Active := true; <== when open is called, the BeforeOpen will be logged. However the afterOpen is not called

Hi
I am having a problem with this function. When issued a ClientDataset.open, the Before Open event is triggered but before the After event is triggered, it returned an Access violation

=============In my code, the SQL is added to TQuery
The Client dataset is link to the Provider. The provider is linked to TQuery.
This application is run on another machine without this error but always gives an access violation on this machine.
Is there a "cache" file that ClientDataset would read after the BeforeOpen event?
Please advise

Hi
In Windows, there is a TWinExit component to allow us to reboot the OS from our software.
Is there one that can reboot the Linux OS?
Or is there a script component whereby the software can call it to reboot?

hi
here is the getItInstall.log.
From GitHub, it states that SynEdit supports up to Delphi 10.4
Could this error due to not able to support 11.1?

Hi
Is there a XML Viewer component rather than using the TWebBrowser component?
Although i can use the TMemo component to load the xml but the output is not that pretty.
Please advise

Ok. I will try to write a small part of the code to see if i can reproduce the same error or not
thanks

We are just learning. I am still learning too
I tried not to create the form but to call showmodal each time user click on the update button
But i will get a problem is that cannot Showmodal when the form is visible.
In the FormClose of aircrafttype form, i set it to caHide instead of caFree
and i have that error.
I feel that even though i have use delphi since Delphi 1, i am still learning how to use this language.
Delphi 6 was the most stable version that i used and I am still using that now to do minor changes to those application written in 2007.
-
The DetailForm close event will have Action := caFree
I tried this way
===== Ghosting Windows
procedure DisableProcessWindowsGhosting;
var
DisableProcessWindowsGhostingProc: procedure;
begin
DisableProcessWindowsGhostingProc := GetProcAddress(
GetModuleHandle('user32.dll'),
'DisableProcessWindowsGhosting');
if Assigned(DisableProcessWindowsGhostingProc) then
DisableProcessWindowsGhostingProc;end;
begin
Application.Initialize;
DisableProcessWindowsGhosting;
TStyleManager.TrySetStyle('Iceberg Classico');
Application.CreateForm(TDataModule1, DataModule1);
Application.CreateForm(TfrmMain, frmMain);
Application.Run;
end.
=======================But will also have the same effect that open and close the form too many times will result in hanging of the application or the form will not show.
Only when i removed the Style Manager, then i will not have this problem.
The Grid is also having its own DrawColumnCell Event
=====================
procedure TfrmMain.dbgACTDrawColumnCell(Sender: TObject; const Rect: TRect;
DataCol: Integer; Column: TColumn; State: TGridDrawState);
var
l_bitmap : TBitmap;
l_rect : TRect;
l_bmpWidth, l_width : integer;
l_str : string;
begin
with dbgACT do begin
if (gdSelected in State) then begin
Canvas.Font.Color := clBlack;
Canvas.Brush.Color := clLime;
end
else begin
if ( (DataSource.Dataset).RecNo mod 2 = 0) then begin
if Canvas.Brush.Color = Color then begin
Canvas.Brush.Color := clSkyBlue;
end;
end;
end;
end;
l_rect := Rect;
l_str := Column.Field.DisplayText;
l_width := dbgACT.Canvas.TextExtent(l_str).cx + 5;
if Column.FieldName = 'ROW_ID' then begin
l_bitmap := TBitmap.create;
try
ImageList2.GetBitmap(tsACT.ImageIndex, l_bitmap);
l_bmpWidth := (Rect.bottom - Rect.Top);
l_rect.Right := Rect.Left + l_bmpWidth;
dbgACT.Canvas.StretchDraw(l_rect, l_bitmap);
finally
l_bitmap.Free;
end;
// cc : reset the output rectangle
l_rect := Rect;
l_rect.Left := l_rect.Left + l_bmpWidth;
l_width := 5 + dbgACT.Canvas.TextExtent(l_str).cx;
end;
if (l_width > Column.Width) then
Column.Width := l_width;
dbgACT.DefaultDrawColumnCell(l_rect, DataCol, (Column as TColumn), State);
end;
====================But not sure if this affected the style manager or not

HI
I am having this funny problem in Delphi 11.1 using VCL.
====
FDetailForm := TfrmAircraftTypesNew.Create(self);
try
(FDetailForm as TfrmAircraftTypesNew).setData(UpdateRow, l_rec);
FDetailForm.Visible := false;
FDetailForm.ShowModal;
finally
l_rec.Free;
end;
FDetailForm := nil;
=======When i open and close the FDetailForm a few times, the detail form would not show and the main window will hang.
See this video to see what i mean.
In the Form Close of the TfrmAircraftTypesNew, i will have
Action := caFree;
Can help why the form is not able to show on top.
I have already tried to put the PopupMode to Explicit.
Another Finding:
when i remove or commented the style from the startup, i did not have this problem of not able to showModal
Application.Initialize;
// TStyleManager.TrySetStyle('Iceberg Classico'); <== Remove/commented this line
Application.CreateForm(TDataModule1, DataModule1);
Application.CreateForm(TfrmMain, frmMain);
Application.Run;Not sure why this style is giving problem....
Please advise

Thanks. need to use locate with disable/enable controls so that the table will not have moving effect.
However, for my dataset, it has 50 columns but the dbgrid can only show first 10 columns on the screen.
If need to show next 10 columns, i will need to scroll to the next 10 columns.
So, when i am looking at the next 10 columns and the table refreshed, can the refresh go to the next 10 columns rather than always go back to the 1st 10 columns?
regards
cris

hi
i have tried using gotobookmark on TQuery with TClientDataset and it could not work.
Will try to use the locate function.
thanks
-
hi
ok i will try it with the locate function for the disablecontrols and enablecontrols
thanks

If there is frequent update to the table, then the user will see the table moving up and down (always locating the record) isnt it?
will this (record pointer moving up and down on the grid) happen?
-
Hi
When the database table is updated and i use dbgrid.datasource.dataset.refresh, the dbgrid is refreshed back to the first row.
Is it possible to refresh the grid without going back to the first row?
This is because if there is frequent update to the database and this Refresh notification is sent to my app each time another app updates the table, the dbgrid will always move back to the first row when it is refreshed.
Any advise

Hi
I managed to implement it in windows using this event
TfrmMain : TForm
Gauge1 : TGauge;
tmrInactivity: TTimer;
procedure FormCreate(Sender: TObject);
procedure tmrInactivityTimer(Sender: TObject);
privateFInactivityTimeout : cardinal;
FInactivityCounter : cardinal;// cc : application event to handle key down and left mouse click
// cc : for activity timeout
procedure ApplicationEventMsg(var Msg: tagMSG; var Handled: Boolean);
publicend;
procedure TfrmMain.FormCreate(Sender: TObject);
var
l_ini : TIniFile;
begin
// this event msg is to capture keyboard and mouse event
Application.OnMessage := ApplicationEventMsg;
// cc : get the amount of seconds allowed before timeout
l_ini := TIniFile.create(ChangeFileExt(Application.ExeName, '.ini'));
FInactivityTimeout := l_ini.ReadInteger('Main', 'Inactivity Timeout', 60);
Gauge1.MaxValue := FInactivityTimeout;
Gauge1.MinValue := 0;
FInactivityCounter := 0;l_ini.Free;
end;
procedure TfrmMain.tmrInactivityTimer(Sender: TObject);
begin
// Inactivity timeout will disconnect every connection
tmrInactivity.Enabled := false;
if (not DataModule1.getLoginSuccess) then begin
FInactivityCounter := 0;
Gauge1.Progress := 0;
tmrInactivity.Enabled := true;
exit;
end;
if (FInactivityCounter > FInactivityTimeout) then begin
DataModule1.closeAll;
end;
FInactivityCounter := 0;
Gauge1.Progress := 0;
end
else begin
FInactivityCounter := FInActivityCounter +1;
Gauge1.Progress := FInactivityCounter;
end;
tmrInactivity.Enabled := true;
end;

Hi
I have another question.
After i use the AddIndex and set the IndexName to the index field created, how can i get back the information of what index field is used and what is the sorting order (asc or desc)
e.g.
l_indexName := 'ABN_REM' + '_INDEX';
l_indexes := TStringList.create;
(TntDBGrid1.DataSource.DataSet as TClientDataSet).GetIndexNames(l_indexes);
if l_indexes.IndexOf(l_indexName) > -1 then
(TntDBGrid1.DataSource.DataSet as TClientDataset).DeleteIndex(l_indexName);
l_indexes.Free;
(TntDBGrid1.DataSource.DataSet as TClientDataset).AddIndex(l_indexName, 'FREE_REM', [ixDescending],'','',0 );(TntDBGrid1.DataSource.DataSet as TClientDataset).IndexName := l_indexName;
In the above code, i have set the IndexName to 'ABN_REM_INDEX' with field 'FREE_REM' used and sort in descending order.
So, how can i get back this information that the field name 'FREE_REM' is used and the sorting is in descending order?

chris

hi
Thanks. I will use the AddIndex function to do the sorting.

Column.Width := l_width; <==
end;
TntDBGrid1.DefaultDrawColumnCell(l_rect, DataCol, (Column as TTntColumn), State);
end;
As i store all the dates as Unix Epoch format. hence i need to translate all the values to date time format when drawn on the grid.
However, is there a way to know when the drawing on the grid is completed?
Or is there a better way to make the grid draw out faster?
Seems like if i dont make it auto size for every column, the drawing is faster.
The longest column is the Foreign Characters and the resizing took quite long there
Is there a way to auto size and auto fit the column which is not done during the drawing part?
please advise

chris
Indy 9.0.18 on Delphi 6. Where can i get 9.0.50?
in Indy
Posted · Edited by ChrisChuah
Finally managed to install Indy 10 on Delphi 6.
I need to remove the indy60.bpl files from c:\windows\system32 as well as c:\program files\borland\delphi6\projects\bpl
also remove all the indy*.bpl from those 2 directories and install the delphi 10 dpk file
seems like need to install packages from different directories as compared to Indy9
Install the design package from Core then Protocol directory.
Is this correct?
