TAdvCardList
Using HTML template items in TDBAdvCardList

In CardTemplate.Items[index].ItemType , you can now set the type to itHTMLText. You can use CardTemplate.Items[index].HTMLTemplate to set the template for the HTML text for the item. DB fields are invoked via <#FIELDNAME> in the template. Other than this, HTML tags can be used described at https://www.tmssoftware.com/site/minihtml.asp

Example:
When TDBAdvCardList is bound to a dataset containing cars that has the fields BRAND, TYPE, CC and PK, these can be combined into on card item in TDBAdvCardList by setting the template to:

'Car:<#BRAND> <#TYPE> Engine: cc:<#CC>/pk:<#PK>'

Combined with setting the CaptionField to BRAND and add an item directly connected to PRICE and COUNTRY fields, the result is:

TMS FMX WebGMaps
Taking a screenshot in Android

The code below takes a screenshot of an instance of TTMSFMXWebGmaps and saves it to a file:

units

AndroidApi.JNI.Embarcadero, AndroidApi.JNI.GraphicsContentViewText, AndroidApi.JNI.JavaTypes, AndroidApi.Helpers, FMX.Objects, IOUtils

code

var
  web: JWebBrowser;
  pic: JPicture;
  bmp: JBitmap;
  c: JCanvas;
  fos: JFileOutputStream;
  fn: string;
begin
  fn := TPath.GetDocumentsPath + PathDelim + ''sample.jpg'';
  web := TJWebBrowser.Wrap(TMSFMXWebGMaps1.NativeBrowser);
  pic := web.capturePicture;
  bmp := TJBitmap.JavaClass.createBitmap(pic.getWidth, pic.getHeight, TJBitmap_Config.JavaClass.ARGB_8888);
  c := TJCanvas.JavaClass.init(bmp);
  pic.draw(c);
  fos := TJFileOutputStream.JavaClass.init(StringToJString(fn));
  if Assigned(fos) then
  begin
    bmp.compress(TJBitmap_CompressFormat.JavaClass.JPEG, 100, fos);
    fos.close;
  end;
end;

TMS FMX WebGMaps
Using the TTMSFMXWebGMaps inside a TTabControl

The TTMSFMXWebGMaps is a wrapper around the native webbrowser. When dropping the component on the form, the webbrowser follows the position and alignment of the wrapper control. There is however a technical limitation when using it as a child of a TTabControl. The native webbrowser doesn''t respond to tab changes, therefore you need to manually toggle the visible property. The following example demonstrates this technique when placing the TTMSFMXWebGMaps control on one of the pages of a TTabControl.

procedure TForm1.TabControl1Change(Sender: TObject);
begin
  TMSFMXWebGMaps1.Visible := TabControl1.ActiveTab = TabItem3;
end;

TCheckListEdit
How to disable an item in the drop-down list

Set ItemEnabled from the event OnShowCheckList, at that point the dropdown checklist is created and ItemEnabled[] can be set.

Example:

procedure TForm1.CheckListEdit1ShowCheckList(Sender: TObject);
begin
  CheckListEdit1.ItemEnabled[2]:=false;
end;

TAdvStringGrid
How to export to PDF

Drop a TAdvgridPDFIO component on the form and connect the TAdvStringGrid to this nonvisual component''s TAdvStringGrid property.
Then simply call:

AdvgridPDFIO.Save(FileName);

After you called Save(FileName) you can call ShellExecute(0,''open'',Char(FileName),nil,nil,SW_NORMAL)
to automatically open this PDF after having it produced. TAdvgridPDFIO comes with settings for header and footer as well as metadata. Header and footer can as such be optionally generated for the PDF file independently from the TAdvStringGrid content.

TAdvGlowButton
How to change the font

Set:
AdvGlowbutton.ParentFont = false
AdvGlowbutton.Appearance.SystemFont = false

When ParentFont = False and Appearance.SystemFont = true, the button will automatically use the recommended system font depending on the operating system used, ie. Segoe UI on Windows 7 and Tahoma on Windows XP.

TAdvSpinEdit
When using the TAdvSpinEdit as a spintype of sptFloat I can not enter a number with decimals

Set AdvSpinEdit.Precision = 2

TAdvSpinEdit
Using the TAdvSpinEdit constraints (MaxValue, MinValue)

If you want that the min/max values are checked, please set

AdvSpinEdit.CheckMinValue := true;
AdvSpinEdit.CheckMaxValue := true;

TMS VCL WebGMaps
Polygons created from the coordinates retrieved from the GetDirections call are not displayed exactly on top of map roads.

Please note that the precision of the route path coordinates retrieved from the GetDirections call is limited. Unfortunately this is a limitation of the Google Maps Directions API which we have no control over.

Alternatively you can use the RenderDirections call to display the route using the Google API instead of using a Polyline. This technique has better precision.

Example:

WebGMaps1.RenderDirections('Hamburg', 'Hannover');

TInspectorBar
How to programmatically open / close a panel

You can programmatically open / close a panel in imMultiPanelActive mode by toggling the Panel.Open: Boolean property.

TMS FlexCel Studio for .NET
When generating Flexcel reports with the registered version, I get an error similar to: "This document was created with the non-commercial version of FlexCel...."

Make sure you don’t have a trial dll installed anywhere in your system. You can right click FlexCel.dll and look at the properties:

If it says “TRIAL” then it is the wrong one. Especially, look in the GAC: c:\windows\assembly
If there is a trial dll in the GAC, it will be used over the local registered dll.
Normally this error happens when there is a trial dll in the GAC, as this has higher priority than the local dlls.
