问题 I have written a function in my iOS and Android apps to open a url. I believe this code will be rejected by iTunes Connect for not connecting over IPv6. This function also raises an error when I build it through Delphi: An access violation occurred at error address 00000001017C4334. (When accessing address 000000000000000) I am using Delphi 10.2.3 Tokyo with Indy 10. How can I fix this error? My code is below: Procedure OpenGoogleForm; Var ipversion : String; Begin // For IPv6 IdTCPClient1

问题 I have created a simple application using Delphi 10.2 Tokyo (using FireMonkey) that displays images and allows you to set the desktop wallpaper for a selected image. The main code that sets the desktop wallpaper is: class procedure TUtilityWin.SetWallpaper(AFileName: String); begin SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, pChar(AFileName), (SPIF_UPDATEINIFILE OR SPIF_SENDWININICHANGE)); end; While this works great when the application runs on the desktop (as a standalone install), it

问题 Having recently received a 'Tumbleweed' badge for my last question, I am not sure whether I should be asking any more questions, but here goes. I am populating a TComboBox with items from a sqlite table and this works fine. In my previous version of Delphi I was able to use ComboBox1.Sorted := True; to sort the items, but this seems to have disappeared in Delphi 10.2. I can sort the items in the table by applying a query and then populate the TComboBox from the sorted table. However, for

问题 After changing to FireDAC I have trouble getting this code to work on MSSQL/Oracle: with DataFormsettings do begin Close; if Params.Count=0 then FetchParams; Params.ParamByName('TT_EMP_ID').Asinteger := AEmpID; Params.ParamByName('TT_FORM').AString := UpperCase(AKey); Open; if (RecordCount>0) then S := FieldByName('TT_VIEWDATA').Asstring; end; AKey and S are both strings.

问题 I'm trying to have a TEditDescendant that contains a reference to another object (MyString), so that when I edit the TEdit text, MyString gets updated and vice-versa. This works when MyString is already existing. However, if I need MyEdit to be able to create a MyString, it does not work. The code below is a minimal example: btnCreateMyEdit creates the myEdit and gives it some text. btnCreateMyString creates an instance of myString btnCheck shows the issues: If btnCheck is created AFTER

问题 I have multiple project groups that I want to compile at batch. There are over 100 projects in there. In 2010 we had a "make" file like this: call "c:\Borland\RAD Studio\19.0\bin\rsvars.bat" "c:\Program Files (x86)\MSBuild\12.0\Bin\MSBuild.exe" /t:Clean,Build Group1.groupproj Under Tokyo it does not work anymore.
