Hello, Do you know any way to extends Windows 7 desktop outside the screen ? I'm using a w7 under VirtualBox with a DPI to 144 to test my application on high resolution, but the desktop resolution is too low and my application is shrunken. The VM use my host resolution, I'de like to set a much higher virtual size.

what i want is to have a small picture of a link (html page). HOWEVER i do not want !! to use WEBBROUSER !!! I would like to have the size of a whole page on a small picture. Is it possible ? Any free code?

Yup, this is also in Delphi possible^^ Alexander Benikowski wrote a little sample wtf? source https://i.redd.it/cozohvgr2h7z.png

Some kind of comment lies : procedure TRegistry.RenameValue(const OldName, NewName: string); [...] begin [...] Len := GetDataSize(OldName); // returns 0 if OldName doesn't exist if Len > 0 then Ok, the comment says Len have to be not equal to 0 if the old value exists. But if we have a look at the implementation of GetDataSize we see this: function TRegistry.GetDataSize(const ValueName: string): Integer; var Info: TRegDataInfo; begin if GetDataInfo(ValueName, Info) then Result := Info.DataSize else Result := -1 ; end; Badumm.... The comment is just wrong. But what are the consequences? - Every value with a size of 0 can not be renamed. When does this happens? - Reg_Binary values can has the size of 0... https://quality.embarcadero.com/browse/RSP-18538 https://quality.embarcadero.com/browse/RSP-18538

How the heck can I prevent the IDE from jumping to the main monitor as soon as I start a debugging session?

If I have a declaration in an attribute like this TestAttr (const aString: string) I can do this: const str1 = '123'; and then [Test (str1)] but if I declare the const like this: const str1: string = '123'; the compiler complains that constant expression is required. Shouldn't I be able to use the second form? Thanks

All new Mac OS apps submitted to the app store must have 64 bit support from January 2018. So make sure you finish and submit your new OS X app before January as Delphi will not support 64 bit on OS X until later 2018 (according to latest road map). https://developer.apple.com/news/?id=06282017a https://developer.apple.com/news/?id=06282017a

Hello! Is there any way to take the content of a checklistbox item and use it as property for a class made by me? In more details: I have a checklist box with items. When the user clicks one of them, the item has to be used as property for a class and present its specific value. I hope I was clear enough. It is hard for me to explain.

If anybody here knows the details about the Dynamic Abstract Factory created by Spring4D and want to help I'll be appreciated.

How to debug resolver issues in Spring4D? When in constructor occur unregistered type parameter (or registered, but uncompletly - without register his constructor parameters types), Spring creates the object with a bad constructor (without parameters, come from base class), but does not warn about it! And an unfinished object is created, with nil in the key fields. How to avoid this, how to detect it?

Hi Everyone. There is no way to instantiate generics at runtime? Eg: TMyGen = class Value: T; Default: T; Min: T; Max: T; end; TMyClass = class // usually.... FMyByte: TMyGen ; FMyWord: TMyGen ; FMyDWord: TMyGen ; // but now I'd like to instatiate the variable FMyValue // as Byte, Word or DWord at runtime FMyValue: TMyGen ; // end; how to do that? It's possible? Thanks.

Can somone comparir delphi xe7 pro to delphi 10 starter? I have the Tokyo edition. I am able to add components and packages manually. Are there any compelling reasons to move to Tokyo Starter for future development? Or stay with XE7 Pro?

Spring4D - How to get the same instance of Logger for a class group? Everything works on interfaces, but I skip interfaces for simplicity. I have a base class: TBaseClass = class fLogger : TLogger; constructor (aLogger : TLogger); end; Two usable classes are inherited from it: TClassA = class(TBaseClass) fWorkClass1 : TWorkClassA; fWorkClass2 : TWorkClassB; end; TClassB = class(TBaseClass) fWorkClass3 : TWorkClassC; fWorkClass4 : TWorkClassD; end; ...which have working classes: TWorkClassA = class fLogger : TLogger; constructor (aLogger : TLogger); end; TWorkClassB = class fLogger : Tlogger; constructor (aLogger : TLogger); end; TWorkClassC = class fLogger : TLogger; constructor (aLogger : TLogger); end; TWorkClassD = class fLogger : Tlogger; constructor (aLogger : TLogger); end; These objects I use directly in the code: var ObjectA : TClassA; ObjectB : TClassB; ObjectA and ObjectB create their own separate workgroups, and I would like...
