Hi all, Playing with new RTTI module, I couldn't find a way to set an event handler with the new utilities. Trying something like this: LProp := TRttiContext.Create.GetType(Form1.ClassInfo).AsInstance.GetProperty('OnClick'); LProp.SetValue(Form1, {a TValue!}); SetValue needs a TValue passed but I've yet to find a way to represent a T...

I just upgraded my BDS2006 Prof to D2010 Prof. I usually use Interbase component (TIBDatabase, etc) to connect with the database. I am thinking about other alternative components. Sadly, Zeos component (6.X) currently still not working with D2009/D2010. DBExpress support FB connection but not in Prof. Version (only in Enterprise/Architec...
I've been asked to re-open a project I wrote in 1998/99 in Delphi 3 and which has been running stably since then. I have the Delphi 3 code base on an aging Windows 98 machine which exists only to keep this project alive. Obviously, I'd like to bring the source code base into the 21st century before undertaking any major revisions. I n...
Is there any way of installing TWebBrowser in Delphi 2010 directly without having to install the Web Development Controls? If I select the Web Development Controls option on the Delphi 2010 setup, TWebBrowser is installed. But this "package" is over 200 MB and I only need TWebBrowser.

I'll shortly be making a purchase decision regarding Delphi 2010. I've always been a "Professional" level developer (meaning I've owned the "Professional" SKU of the product before), but I'm considering buying the Enterprise edition this time.

Hi, Have installed trial version of Delphi 2010, and hoped to get a look at DeHL. There must be something that I have missed out on, though, cause I can't find out how to include any of the units without getting a 'file not found'-error at compile time... What I have done, is to include the path to the pas-files in the projects 'Incl...

Is there any Delphi D2010 function like PosEx that finds a sub-string inside a string starting from the end of the string? I'm removing all the calls to the FastStrings library and one of the functions I was using was FastPosBack: function FastPosBack(const aSourceString, aFindString : AnsiString; const aSourceLen, aFindLen, StartPos :...
Is there any comparable function like Pos that is not case-sensitive in D2010 (unicode)? I know I can use Pos(AnsiUpperCase(FindString), AnsiUpperCase(SourceString)) but that adds a lot of processing time by converting the strings to uppercase every time the function is called. For example, on a 1000000 loop, Pos takes 78ms while conve...

I have a project with a lot of frames, and when I reload my project, they are resized to a width and height of 443x270, or thereabout. I do reside the frames at runtime, but I wish they would remain as I create them at design time. I use the non-embedded, classic undocked view. Anyone has any idea on how to have the frames keep their s...
