Multi-folder usage of IrfanView’s batch mode

Batch conversion tool (B in main screen or File > Batch Conversion/Rename) in IrfanView is both flexible and powerful tool that allows you (as menu item says) to: quickly convert many images, quickly rename many files or mix these two operations.

The Add All button in mentioned tool’s window is even more powerful, because it lets you add files (to be converted or renamed) from given folder and all subfolders. But not everyone knows, that the same goes for saving converted files. They also can be placed by IrfanView in many folders

Enabling Polish letters in Delphi 2010

Using non-Latin keyboards with Delphi and non-Latin characters in code was always a big problem in Delphi.

To enable correct support in Delphi 10 you have to:

  • go to Tools > Options > Editor Options > Key Mappings,
  • uncheck Use Ctrl-Alt keys.

Hopefully in Delphi 2010 you can do this from IDE settings. You don’t have to play with stupid .reg files to change some dully strings in Windows Registry, as you were forced in Delphi 5 to achieve the same.

Remove system menu button from PhoneGap application

By default your PhoneGap application will contain system menu button, even on those systems (Android 4.0+) that doesn’t support this button any more (i.e. applications written for this system should not use this button; it is handled anyway and you can use it, if you really wish to).

On most new devices user pressing this button will be simply ignored by system and nothing will happen. So, this problem reduces itself to purely aesthetic means (whether you care about seeing that unusable button on system bar, when your app is active, or not).

However, there are reports, that PhoneGap applications crashes on small group of devices, when user presses this not handled system menu button. In this case, more radical solutions must be considered.

A link to the same URL with a different port

Let’s say, that you need to make a <a href=""></a> link, that will point you to the very same URL (as page, in which have this link), but to a different port. Even though there are no reasons for not implementing support for links like <a href=":8080">jump</a>, as of writing this, such support is not implemented in any known browser. And thus, neither this link work nor pure-HTML solution is available.

You must hire Javascript to resolve this problem.

AdMob Plugin and pure-Javascript ads in PhoneGap Build application

It all started with this Stack Overflow question asked by me 2,5 year ago, when I was attempting to strike with ads in mobile applications for the first time. I’m still using PhoneGap Build only therefore in the past I was very limited to only these ad networks, that supported displaying their add through pure Javascript only. However, all the things had changed radically, with introduction of npm plugins to PhoneGap Build.
