TdxAzureMapResponse.ErrorInfo Property

Provides access to detailed error information if the current server query is not successful.

Declaration

property ErrorInfo: TdxAzureMapErrorDetail read;

Property Value

Type	Description
TdxAzureMapErrorDetail	Stores detailed information on an Azure Maps server query. The property value is nil (in Delphi) or nullptr (in C++Builder) if an Azure Maps server does not return query error information.

Remarks

Use ErrorInfo and StatusCode properties to obtain detailed error information if the IsSuccess property returns False.

Code Example: Validate Server Response

The code example in this topic section demonstrates a function that checks if an Azure Maps server response is valid. The function returns False and displays a message box with the corresponding error message if a server query fails.

Delphi

uses
  dxMessageDialog;  // Declares the dxMessageDlg global function
// ...

function TMyForm.ValidateServerResponse(AResponse: TdxAzureMapResponse): Boolean;
begin
  if AResponse <> nil then
  begin
    Result := AResponse.IsSuccess;
    if not Result and Assigned(AResponse.ErrorInfo) then
      dxMessageDlg(AResponse.ErrorInfo.Message, TMsgDlgType.mtError, [mbOK], 0);
  end
  else
    Result := False;
end;

C++

#include "dxMessageDialog.hpp"  // This header declares the dxMessageDlg global function
// ...

bool __fastcall TMyForm::ValidateServerResponse(TdxAzureMapResponse *AResponse)
{
  if(AResponse != nullptr)
  {
    if(AResponse->IsSuccess) { return true; }
    else
    {
      if(AResponse->ErrorInfo != nullptr)
        dxMessageDlg(AResponse->ErrorInfo->Message, TMsgDlgType::mtError, TMsgDlgButtons() << mbOK, 0);
    }
  }
  return false;
}
