I'm facing with an issue, here is my code
constructor TORAThread.Create;
begin
inherited Create(True);
ORAFDcon_Ora := TFDConnection.Create(nil);
ORAFDPhysOracleDriverLink := TFDPhysOracleDriverLink.Create(nil);
ORAFDGUIxWaitCursor := TFDGUIxWaitCursor.Create(nil);
ORAStorPRoc := TFDStoredProc.Create(nil);
ORAFDcon_Ora.DriverName := 'ora';
ORAFDcon_Ora.LoginPrompt := False;
ORAFDcon_Ora.Params.LoadFromFile('ORAconfig.ini');
ORAFDcon_Ora.CheckConnectionDef;
ORAFDcon_Ora.ResourceOptions.AutoConnect := True;
ORAFDcon_Ora.ResourceOptions.AutoReconnect := True;
ORAFDcon_Ora.ResourceOptions.KeepConnection := True;
ORAFDcon_Ora.ResourceOptions.CmdExecMode := amNonBlocking;
procedure TORAThread.Execute;
begin
ORAFDcon_Ora.Connected := True;
while not terminated do
begin
//somejobs
end;
When I start the thread and VPN connection is not alive, my GUI freezes
Whats wrong?

I am creating a program, and I need to display an image and then block input for a few seconds before allowing it again. The problem I am running into is that Delphi is not running the code in order and is executing the Sleep() command before the image command. I have run into this problem before when using Sleep() with a video before displaying a message.
The code looks as follows:
procedure TtForm.WindowsMediaPlayer2Click(ASender: TObject;
nButton, nShiftState: SmallInt; fX, fY: Integer);
Var
buttonSelected: Integer;
begin
buttonSelected := MessageDlg('Well done Monkey!-_-', mtError, mbOKCancel, 0);
if buttonSelected = mrOK then
begin
Pages.Visible := False;
WindowsMediaPlayer2.Visible := False;
imgEroor.BringToFront;
BorderStyle := bsNone;
WindowState := wsMaximized;
imgEroor.Top := 0;
imgEroor.Left := 0;
imgEroor.Width := Screen.Width;
imgEroor.Height := Screen.Height;
imgEroor.BringToFront;
BlockInput(True);
Sleep(10000);
BlockInput(False);
end;
if buttonSelected = mrCancel then
begin
Pages.Visible := False;
WindowsMediaPlayer2.Visible := False;
imgEroor.BringToFront;
BorderStyle := bsNone;
WindowState := wsMaximized;
imgEroor.Top := 0;
imgEroor.Left := 0;
imgEroor.Width := Screen.Width;
imgEroor.Height := Screen.Height;
imgEroor.BringToFront;
BlockInput(True);
Sleep(10000);
BlockInput(False);
end;
end;
Where is this strins resources is stored on the Windows?
I need to show size corectly on native language of installed Windows.
Strings are very specific to the application that is using it. There are no generic string resouce in windows that an application can use. Of course you can write a program to search the resource in the windows folder to see which resource dll has the string that you are looking for and then use that resource dll in your application, but that is unadvisable. The reason being that, any new update of the windows that brings in resource dll changes can break your application.
As the other poster advises, you are better of writing your own resource dll and localize it in the languages that you want to support your application.
This is possible with disk quota library which is available since Windows XP:
function FindStringResourceEx(AInstance: HINST; AStringID: UINT; ALangID: UINT): PWideChar;
var
Res: HRSRC;
LoadedRes: HGLOBAL;
I: Integer;
begin
Result := nil;
Res := FindResourceEx(AInstance, RT_STRING, MAKEINTRESOURCE(AStringID div 16 + 1), ALangID);
if Res <> 0 then begin
LoadedRes := LoadResource(AInstance, Res);
if LoadedRes <> 0 then
try
Result := PChar(LockResource(LoadedRes));
if Assigned(Result) then
try
for I := 0 to (AStringID and 15) - 1 do
Inc(Result, PWord(Result)^ + 1);
finally
UnlockResource(THandle(Result));
end;
finally
FreeResource(LoadedRes);
end;
end;
end;
function GetSizeStrings(out sBytes, sKB, sMB, sGB, sTB, sPB, sEB: string): Boolean;
var
hLib: HMODULE;
sRes: string;
I: Integer;
SL: TStringList;
begin
Result := False;
hLib := LoadLibrary('dskquoui.dll');
if hLib > 0 then
try
SL := TStringList.Create;
try
sRes := FindStringResourceEx(hLib, 14472, MAKELANGID(LANG_NEUTRAL, SUBLANG_NEUTRAL));
Result := sRes <> '';
if Result then begin
sRes := sRes.Remove(0, 1);
I := sRes.IndexOf(#$B);
if I > -1 then
sRes := sRes.Remove(I);
SL.Delimiter := #2;
SL.DelimitedText := sRes;
sBytes := SL[0]; // bytes
sKB := SL[1]; // KB
sMB := SL[2]; // MB
sGB := SL[3]; // GB
sTB := SL[4]; // TB
sPB := SL[5]; // PB
sEB := SL[6]; // EB
end;
finally
SL.Free;
end;
finally
FreeLibrary(hLib);
end;
if not Result then begin
sBytes := 'bytes';
sKB := 'KB';
sMB := 'MB';
sGB := 'GB';
sTB := 'TB';
sPB := 'PB';
sEB := 'EB';
end;
end;
When changing a language in combo box (without clicking ok), I want to change texts of the dialog (label, form caption, button caption)
procedure SelectLanguage();
var
LanguageForm: TSetupForm;

LanguageForm.ClientWidth := ScaleX(297);

LangCombo.Left := ScaleX(16);
LangCombo.Top := ScaleY(56);
LangCombo.Width := ScaleX(273);

for I := 0 to Languages.Count - 1 do
begin

L := Copy(Languages.Strings[I], 0, P - 1);
S := Copy(Languages.Strings[I], P + 1, Length(Languages.Strings[I]) - P);
LangCombo.Items.Add(S);
if L = ActiveLanguage then
LangCombo.ItemIndex := I;
end;
if LanguageForm.ShowModal = mrOK then
begin
{ ... }
end;
end;
function InitializeSetup(): Boolean;
begin
SelectLanguage();
{ ... }
end;
Spanish: first language.
I select English and no change the language of the language selector.
You have the code already. You just need to make some local variables in the SelectLanguage function global, so they can be used in the LangChange function:
var
LanguageForm: TSetupForm;
SelectLabel: TNewStaticText;
CancelButton: TNewButton;
procedure LangChange(Sender : TObject);
begin
case TNewComboBox(Sender).ItemIndex of
0: { English }
begin
SelectLabel.Caption := 'Select the language to use during the installation:';
CancelButton.Caption := 'Cancel';
LanguageForm.Caption := 'Select setup language';
end;
1: { Czech }
begin
SelectLabel.Caption := 'Zvolte jazyk, kter'+#$FD+' se m'+#$E1+' pou'+#$17E+#$ED+'t b'+#$11B+'hem instalace:';
CancelButton.Caption := 'Storno';
LanguageForm.Caption := 'V'+#$FD+'b'+#$11B+'r jazyka pr'+#$16F+'vodce instalac'+#$ED+'';
end;
end;
end;
In the SelectLanguage, remove these the declarations of local variables:
LanguageForm: TSetupForm;
SelectLabel: TNewStaticText;
CancelButton: TNewButton;
And assign the LangChange event handler:
LangCombo.OnChange := #LangChange;
How to programmatically add an application or port to Windows Firewall on Windows XP?
Try this code extracted from our open source SQlite3UI.pas unit:
function GetXPFirewall(var fwMgr, profile: OleVariant): boolean;
begin
Result := (Win32Platform=VER_PLATFORM_WIN32_NT) and
(Win32MajorVersion>5) or ((Win32MajorVersion=5) and (Win32MinorVersion>0));
if result then // need Windows XP at least
try
fwMgr := CreateOleObject('HNetCfg.FwMgr');
profile := fwMgr.LocalPolicy.CurrentProfile;
except
on E: Exception do
result := false;
end;
end;
const
NET_FW_PROFILE_DOMAIN = 0;
NET_FW_PROFILE_STANDARD = 1;
NET_FW_IP_VERSION_ANY = 2;
NET_FW_IP_PROTOCOL_UDP = 17;
NET_FW_IP_PROTOCOL_TCP = 6;
NET_FW_SCOPE_ALL = 0;
NET_FW_SCOPE_LOCAL_SUBNET = 1;
procedure AddApplicationToXPFirewall(const EntryName, ApplicationPathAndExe: string);
var fwMgr, profile, app: OleVariant;
begin
if GetXPFirewall(fwMgr,profile) then
try
if profile.FirewallEnabled then begin
app := CreateOLEObject('HNetCfg.FwAuthorizedApplication');
try
app.ProcessImageFileName := ApplicationPathAndExe;
app.Name := EntryName;
app.Scope := NET_FW_SCOPE_ALL;
app.IpVersion := NET_FW_IP_VERSION_ANY;
app.Enabled :=true;
profile.AuthorizedApplications.Add(app);
finally
app := varNull;
end;
end;
finally
profile := varNull;
fwMgr := varNull;
end;
end;
procedure AddPortToXPFirewall(const EntryName: string; PortNumber: cardinal);
var fwMgr, profile, port: OleVariant;
begin
if GetXPFirewall(fwMgr,profile) then
try
if profile.FirewallEnabled then begin
port := CreateOLEObject('HNetCfg.FWOpenPort');
port.Name := EntryName;
port.Protocol := NET_FW_IP_PROTOCOL_TCP;
port.Port := PortNumber;
port.Scope := NET_FW_SCOPE_ALL;
port.Enabled := true;
profile.GloballyOpenPorts.Add(port);
end;
finally
port := varNull;
profile := varNull;
fwMgr := varNull;
end;
end;
It will allow you to add an application or a port to the XP firewall.
Should work from Delphi 6 up to XE.
