问题 I do not understand what is the purpose of PixelsPerInch property... It seems it is useless. If Scaled is checked, PixelsPerInch cannot be modified. If Scaled is unchecked and PixelsPerInch is changed, the form size an font is scaled to a fixed value, regardless of the value you entered in PixelsPerInch field. Of course, I checked the form size at runtime. 回答1: Scaled is True In the dfm file the PixelsPerInch property contains the screen DPI value used when the form was designed. This is

问题 So if I have prepared a REST Request, is there a way that I can view the output of it before sending for debugging purposes? So: LRequest.Client := LClient; LRequest.Method := rmPOST; LRequest.Resource := AUTH_PATH; LRequest.Accept := 'application/json'; // required parameters LRequest.AddParameter(ExCode, AuthCode, pkGETorPOST); LRequest.AddParameter(ExRedirectURI, RedirectionEndPoint, pkGETorPOST); LRequest.AddParameter(ExGrantType, ExAuthorizationCode, pkGETorPOST); LRequest.AddParameter(

问题 I am in the process of upgrading from Delphi 10.2.3 to 10.3.3. My android apps are now not generating an OnKeyDown event from the virtual keyboard for the Return key. I have confirmed this using a very basic newly created project so it is nothing to do with the conversion from 10.2.3 it seems. Any ideas would be appreciated. QA at embarcadero have come back with the following response: "According to this documentation - Handle keyboard actions or this - KeyEvent : When handling keyboard

问题 There has been a change to the HTTPRIO.HTTPWebNode.OnBeforePost event in Delphi 10.3. Before Delphi 10.3, the event handler was defined this way, and it worked perfectly: procedure TForm1.HTTPRIO1HTTPWebNode1BeforePost(const HTTPReqResp: THTTPReqResp; Data: Pointer); var auth: String; begin auth := 'Authorization: Basic ' + IdEncoderMIME1.EncodeString('user:password'); HttpAddRequestHeaders(Data, PChar(auth), Length(auth), HTTP_ADDREQ_FLAG_ADD); end; In Delphi 10.3, the Data parameter is gone

问题 In Delphi Tokyo 10.2.x a ESOAPHTTPException was an Exception descendant with a StatusCode property set in the creator: ESOAPHTTPException = class(Exception) private FStatusCode: Integer; public {$IF CompilerVersion <= 15.0} constructor Create(const Msg: string; SCode: Integer = 0); {$ELSE} constructor Create(const Msg: string; SCode: Integer = 0; Dummy: Integer = 0); {$IFEND} constructor CreateFmt(const Msg: string; const Args: array of const; SCode: Integer = 0; Dummy: Integer = 0); property

问题 I have hit this issue off and on in Delphi 10.3 using FireDAC and the EMS Rad Server. I have not experienced it in Delphi 10.2 or below, but I am not using FireDAC anywhere but in Delphi 10.3. The issue I am experiencing is some special characters seem to be getting stripped out of the SQL statements before they reach the Database. For example, if I run: update messageread set MessageDeliveredDateTime = '8/11/2020 6:33:45 PM' where messageread.dts in ('5/7/2020 12:48:20 PM-!+[[786', '5/7/2020

问题 I try to set a 6 s connection time out for non responding sites, on a TNetHTTPClient with : NetHTTPClient1.ConnectionTimeout := 6000; But it doesn't work, the timeout seems always the same default ( about 1 mn) Am I missing something with the ConnectionTimeout or with my code ? Edit : OK, my mistake, for this tests I used a (bad) proxy and it was the proxy which was not responding. So it seems that the ConnectionTimeout is not efficient in case of not responding proxy. I will post mode code
