They are used to attach the glass to the window regulator, the mechanism that moves the glass up and down.
You light a flame at the holes in the bottom of the glass part with the propane on, the glass will fill with propane and catch fire.
Glass Window dates back as far as the Babylonian empire in 3000 BCE, however the use of holes in walls has been around for much longer.
If its one of those cheap Airhogs Helicopters, Just attach the little holes on the post and attach them to the top one. It should work
remove panelling of the door. look at the bottom for the screws attached to the glass and put them back in the holes on the metal track on the bottom. fix the rubber guides on the side so that nothing blocks the way of the glass. keep the screws on the glass, that you put in the whole, sort of loose to adjust for centering. careful, it might pop out sometimes. you might have to unscrew the bolts that hold the rubber guides up, in order to put the glass in. this depends on how messed up your window/door/galss is. once everything is on track, tighten screws on the bottom of the track were you put into the wholes, and tighten. test the window before you put everything back. adjust if neccessary, then put everything back. this was on a 99 civic hatchback dx. might be different for other cars, but this is the back idea.
If your window is manual, remove the crank handle. If electric, carefully remove the switch panel and disconnect the electrical connector(s). Remove the interior trim panel, and then carefully remove the plastic insulation sheet from the door. Look through the holes in the door sheet metal. At the bottom of the window glass, you should see the metal support for the glass. There will be two large hex-head bolts threaded into either yellow or orange plastic that hold the glass to its support brackett. Using the normal window controls, move the window up or down until the bolts line up with appropriate access holes in the sheet metal, and then unscrew them with a 5/8" socket and extension (you shouldn't have to use a ratchet, as the bolts aren't that tight.) When the bolts are removed, remove the plastic inserts that go through the matching holes in the glass. I recommend using a long pair of hemostats for this. Also, you may have to work your hand around behind the glass to push the inserts out. After they are removed, you should be able to lift the glass out of the door. Installation is the reverse.
In early drilling of holes in glass garlic was used.

As long as the glass is not tempered then yes, you need a diamond coated hole saw or a dremel with a diamond bit. The bottom of most tanks are tempered so i would suggest avoiding the bottom, sides are mostly not tempered but some are.
The round windows in staterooms or cabins on board ships are called port holes. These round windows would be kept closed when the ship is at sea, but could be opened when the ship is at anchor or docked in port.
TAKE OFF THE DOOR PANEL STICK A A SCREW DRIVER IN ONE OF THE HOLES TO GET UP UNDER THE GLASS PUSH THE GLASS UP SLIGHTLY UNTILL YOU GET AHOLD OF THE GLASS THROUGH THE TOP OF YOUR DOOR U CAN THEN PULL UP ON THE GLASS TILLL YOU GET IT WHER U WANT IT U MAY HAVE TO DRILL A HOLE IN THE TRACK SO THAT THE WINDOW DOES NOT FALL BACK DOWN I DONT REMEMBER EXACTLY HOW IT LOOKS
first determine if the window is salvageable, meaning you can replace the glass. If you can NOT save the window then simply use a screw gun to fasten a piece of plywood cut at the proper dimensions to cover the window. The plywood should cover from one side of the frame to the opposite side. I would measure the total width of the window and subtract one quarter of an inch. If you can salvage the window then you will have to nail/screw the plywood into the material that is creating the 'outer skin of the building, i.e. brick, siding, stone etc. I would first attach a nailing board onto the window opening then screw the plywood to the nailer. You will have to caulk the holes in the 'exterior skin' when the window has been replaced. Any confident contractor will be able to do this with no trouble at all.
