I'm trying to iterate the DOM using TChromium and because i use Delphi 2007 i can't use anonymous methods, so i created a class inherited of TCEFDomVisitorOwn. My code is as below, but for some reason the 'visit' procedure is never called, so nothings happens. unit udomprinc; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, ceflib, cefvcl; type TForm1 = class(TForm) Chromium1: TChromium; procedure FormCreate(Sender: TObject); procedure Chromium1LoadEnd(Sender: TObject; const browser: ICefBrowser; const frame: ICefFrame; httpStatusCode: Integer)

I am familiar with Jeff Atwood's article about how errors are always the programmer's fault , but I believe I have really and truly found a bug in a Delphi .pas file. Specifically, I'm using Delphi 2007, and the error is on line 955 of the DBCommon.pas file, which on my machine is located here: C:\program files\codegear\rad studio\5.0\source\Win32\db\DBCommon.pas And the code is this: ... FieldIndex := StrToInt(Token); if DataSet.FieldCount >= FieldIndex then LastField := DataSet.Fields[FieldIndex-1].FieldName else ... If "Token" has a value of zero, then we try to access index -1 of DataSet

I have a Base64 binary string that is part of an XML document that is sent to us by a 3rd party supplier, I would like to be able to save it back to its original file format (jpg). Using the accepted answer from this question "saving a base64 string to disk as a binary using php" I can save the string to a jpg with little effort, so I know the string is in good form and is a JPG file. But how do I do this in Delphi 2007? Looking on the net I found a tutorial on how to convert the Base64 into a TByteDynArray, and save that, but it doesn't work right. I have also played about with Indy's

The situation is simple. I've created a complex Delphi application which uses several different techniques. The main application is a WIN32 module but a few parts are developed as .NET assemblies. It also communicates with a web service or retrieves data from a specific website. It keeps most of it's user-data inside an MS Access database with some additional settings inside the Registry. In-memory, all data is converted inside an XML document, which is occasionally saved to disk as backup in case the system crashes. (Thus allowing the user to recover his data.) There's also some data in XML

How I can get information about Windows OS type? Is it 32bit or 64bit? How I can get this information programatically? You need to use GetProcAddress() to check the availability of the IsWow64Process() function at runtime, like so: function Is64BitWindows: boolean; type TIsWow64Process = function(hProcess: THandle; var Wow64Process: BOOL): BOOL; stdcall; var DLLHandle: THandle; pIsWow64Process: TIsWow64Process; IsWow64: BOOL; begin Result := False; DllHandle := LoadLibrary('kernel32.dll'); if DLLHandle <> 0 then begin pIsWow64Process := GetProcAddress(DLLHandle, 'IsWow64Process'); Result :=

Hello how can I find the smallest and biggest number in delphi? Suppose I have 10 different numbers stored in an array: How can I find the biggest number and smallest numbers in my array? Simply loop through the array in linear fashion. Keep a variable for the min value and one for the max values. Initialise both to the first value in the array. Then for each element, update the min or max value if that element is less than or greater than the min or max value respectively. minval := a[0]; maxval := a[0]; for i := 1 to Count-1 do begin if a[i]<minval then minval := a[i] else if a[i]>maxval
