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 converting to uppercase takes 764ms. str1 := 'dfkfkL%&/s"#<.676505'; for i := 0 to 1000000 do PosEx('#<.', str1, 1); // Takes 78ms for i := 0 to 1000000 do PosEx(AnsiUpperCase('#<.'), AnsiUpperCase(str1), 1); // Takes 764ms I know that to improve the performance of

I've always heard that Delphi can do almost anything C++ can do...except write Windows drivers. Is this correct, and if so, why is that? I recently read a blog post online that may indicate a possible solution for writing drivers with Delphi , but it's 3 years old and I don't know how accurate this information is. So, with the latest version of Delphi (2010), would it be technically possible to write a Windows driver? It may be technically possible to write some drivers with Delphi, but as far as a general answer goes, I'd say: you can't easily write drivers with Delphi . First, there's a

Our company have a software that has been in development for over 10 years, so there are some really dated stuff in there. It's still quite functional and everything, but I see the new features on Delphi XE and it makes me want to switch. Problem is that the source code itself is over 300mb of .pas files (1gb total with components, etc). We're using custom components, old jvcl stuff and the latest devexpress. How hard can I expect things to be if I decide to migrate from Delphi 7 to Delphi XE? Thank you. The only real problem is conversion to Unicode. You should learn how Unicode support is

I am trying to use the Rand() function within MySQL to select a random record but I am getting a syntax error in the Rand() LIMIT line qryCards.SQL.Add('SELECT * FROM tblCards WHERE Card_Rarity = "Epic"'); qryCards.Open; iCount := qryCards.RecordCount; qryCards.Close; qryCards.SQL.Clear; qryCards.SQL.Add('SELECT * FROM tblCards ORDER BY rand(' + IntToStr(iCount) + ') LIMIT 1'); qryCards.Open; ShowMessage(qryCards.FieldByName('Card_Name').AsString); First off, you are not using RAND() correctly. It returns a decimal number 0 <= N < 1 . The input value is a seed, not an upper limit like you are
