问题 Does anyone know how to turn off the anti-aliasing in TChart for Firemonkey in Delphi XE2? 回答1: FireMonkey Canvas does not allow enabling or disabling anti-alias for individual controls.

问题 I have written a Delphi function that loads data from a .dat file into a string list. It then decodes the string list and assigns to a string variable. The contents of the string use the '#' symbol as a separator. How can I then take the contents of this string and then assign its contents to local variables? // Function loads data from a dat file and assigns to a String List. function TfrmMain.LoadFromFile; var index, Count : integer; profileFile, DecodedString : string; begin // Open a file

问题 I made a small program in Delphi 7 to show some details of all attached HID devices. I only used system files like SetupAPI , Moduleloader and HID.pas . This works perfect. When I take the same code and compile it in Delphi XE2 or (2010 for that matter), it fails to produce the required output. Probably this has something to do with pointer casting or so, but I cannot find the root cause. Can anyone help. This is my code: unit Unit1; interface uses Windows, Messages, SysUtils, Variants,

问题 I'd like to get a file last modified time in Delphi. Normally something like FileAge() would do the trick, only the problem is: if I overwrite * File A * with File B using CopyFile , File A's modified date is not updated with current overwrite time as it should(?)

My whole application relies on modification time to decide whether or not

问题 In my (XE2) IDE I constantly have to switch the settings for Project Options/ Debugger / Parameters because I'm testing for different client configurations, databases etc. The Parameters dropdown list is becoming unmanageable. Since these have no descriptions either, it's even hard to figure out which ones to remove (How can I clean the Parameters field in the Run -> Parameters menu?). Any smart ideas on managing these? In an ideal word I would like to give them a tag/description, reorder

问题 I know there's plenty ways of enumerating computers and devices on a network, but how do I show just computers available for Windows file sharing? I need to provide a tree view of network computers and their shared folders. I know I could use existing shell controls for this, but I would rather keep it in my own tree view. It will only list those computers on the network which have shared folders. Past the computers and their shared folders, I can do the individual directory listing part
