Intercepting print dialog

[salvadordf]

As far as I know, there are two ways to disable printing :

• Overwrite the window.print JavaScript function. Add this code :

  Code: Select all

  TChromium.ExecuteJavascript('window.print=function(){}', 'about:blank', 0);

• Hook the PrintDlg and PrintDlgEx functions in the Windows API. For more details about this, read this post message :

After reading a little more about this kind of problems I would try to use the TChromium.OnLoadStart event and add this code inside that event :

Code: Select all

frame.ExecuteJavascript('window.print=function(){}', 'about:blank', 0);

This would override the window.print function in every loaded frame.
