TMS VCL Chart
Using the Popup ToolBar
Using the Popup ToolBar
The chart supports displaying a helper popup toolbar that offers various functionality such as changing the series type, fill and line color as well a specifying the marker type and label visibility.
To enable the popup, set Popup.Enabled := True;
AdvChartView1.Popup.Enabled := True;
When clicking on a series point, slice, or bar depending on the chosen series type the popup will be shown and initialized based on the current settings of the series.
The popup options can be configured via the Popup.Options property. This allows you to show more or less dropdown pickers depending on the series configuration. Below is a sample that demonstrates displaying the full set of options versus a limited set with line color, type and width.
AdvChartView1.Popup.Options := AllOptions;
AdvChartView1.Popup.Options := [ctpoStroke, ctpoLineStyle, ctpoLineWidth];
Serial Comms over Bluetooth
If you have a Windows virtual serial port driver for your Bluetooth hardware, you can use TMS Async to communicate via the virtual Windows serial port over Bluetooth.
TWebUpdate
TimeOut & ReceiveTimeOut
TimeOut & ReceiveTimeOut
First of all, TWebUpdate has a function .Connected: boolean that can return whether the PC is connected to the internet or not.
TimeOut:
Sets or retrieves an unsigned long integer value that contains the time-out value, in milliseconds, to use for Internet connection requests. Setting this option to infinite (0xFFFFFFFF) will disable this timer.
ReceiveTimeOut:
Sets or retrieves an unsigned long integer value that contains the time-out value, in milliseconds, to receive a response to a request. If the response takes longer than this time-out value, the request is canceled
Default values are zero, meaning , these values are not configured and system defaults are used.
TWebPost
Post to a https URL
Post to a https URL
TWebPost can handle HTTPS under certain circumstances. (depends largely on the server side implementation of the HTTPS POST) To use HTTPS, use the WebPost.port = 443

Create a new custom tableview descending from TTMSFMXTableView or TTMSFMXTableViewEx
Create a new custom tableview descending from TTMSFMXTableView or TTMSFMXTableViewEx
When you create a new TableView that descends from our TTMSFMXTableView control, make sure that in the new class, you override the protected method GetDefaultStyleLookupName to ensure your new TableView control uses the base class TTMSFMXTableView default style resource. Sample code:
TTMSFMXTableViewEx = class(TTMSFMXTableView) private { Private declarations } protected { Protected declarations } function GetDefaultStyleLookupName: string; override; function GetClassStyleName: String; override; public { Public declarations } procedure ApplyStyle; override; published { Published declarations } end; function TTMSFMXTableViewEx.GetClassStyleName: String; begin Result := ClassParent.ClassName + ''style''; Delete(Result, 1, 1); end; function TTMSFMXTableViewEx.GetDefaultStyleLookupName: string; begin Result := GetClassStyleName; end;
function TTMSFMXTableViewEx.GetClassStyleName: String; begin Result := ClassParent.ClassParent.ClassName + ''style''; Delete(Result, 1, 1); end;

W1035 Return value of function '%s' might be undefined
W1035 Return value of function '%s' might be undefined
Did you know that Delphi compiler warning "W1035 Return value of function ''%s'' might be undefined" works only with simple types like integers, but never work for managed types like strings or interfaces?
Using FixInsight''s rule W521 you can handle ANY type:
function TForm1.TestInteger: Integer;
begin
end;
Delphi Compiler: W1035 Return value of function ''TForm1.TestInteger'' might be undefined
FixInsight: W521 Return value of function ''TForm1.TestInteger'' might be undefined
function TForm1.TestString: string;
begin
end;
Delphi Compiler: NOTHING
FixInsight: W521 Return value of function ''TForm1.TestString'' might be undefined
