This is a small (and expanding) group of simple utility procedures which perform functions which I find that I use very frequently. So far, the procedures are:
GetAppDirectoryPath(BPath* appPath)
This, when called from within a BeApplication, sets 'appPath' to the directory in which the application resides.
GetAppPath(BPath* appPath)
Like the above, this sets 'appPath' to the application, so it can be used for accessing the application file.
BBitmap* GetAppBitmap(uint32 resID)
This returns a bitmap reconstituted from an application's resource file (assuming that you added one to begin with). The application 'Bitmap2Rsrc' can be used to do this.
