In Delphi (2007) ShareMem must be declared as the first item in the uses of the unit you are using and also in your application file. Then declare:
function WebUpdate(strPath: string): Integer; stdcall external'wuw4.dll';
Then call the exported WebUpdate() function with:
procedure CheckForUpdatesExecute();var strPath: string; intResult: integer;begin strPath := 'https://mycompany.com/myscript.txt' intResult := WebUpdate(strPath);if intResult = 0 then ShowMessage('Unable to check for updates because the update components are not installed.');end;
That's it! You are ready to move on to the next step - authoring your update script.
Alternatively, install the supplied wuwstub.exe utilty into the same folder as your application and launch it as a child process, passing the URL of your update script as a command line argument. (Note: this method needs to be used for 64 bit applications because wuw4.dll is a 32 bit DLL. Wuwstub.exe adds only 28kb to your application's footprint.)
