According to the MSDN website , the number of dimensions are saved as a descriptor in the file, but I can't figure out how to access/load them. The example below works, but only because I have hard coded the array dimensions. The commented out line works in a dynamic sense, but the array's dimensions are lost in the process. Here's some sample code: Sub WriteArray () Dim file_name As String Dim file_length As Long Dim fnum As Integer Dim values () As

Now, I want to calculate the euclidean distance between each point of this point set (xa[0], ya[0], za[0] and so on) with all the points of an another point set (xb, yb, zb) and every time store the minimum distance in a new array. Let's say that xa.shape = (11,), ya.shape = (11,), za.shape= (11,). Respectively, xb.shape = (13,), yb.shape = (13,), zb.shape = (13,). What I want to do is to take each time one xa[],ya[],za[], and calculate

When the player (purple shirt) walks near a cat, it will "rescue" it... which basically removes the animalContainer from the ContainerOfAnimals (thereby removing animalContainer's BMP from the stage), and then add the id of that animalContainer to a rescuedTotal_Array ...

To iterate in the right way an Array you have to use the following: for( var i=0; i < [1,2,3].length; i++){ ... } 回答2: Try instead : var arr = [1, 2, 3];

I have an array with database fieldnames as key and object properties as values like this: $properties = array("userid" => "user['userid']", "city" => "hometown"); foreach ($properties as $field => $property ) { $value1 = $db->$field; $value2 = $obj->$property; } This works for the property hometown but doesn't work voor de property user['userid']. What is the correct way to adress the property variable? I also tried several things like: ${property} or {$property} but without luck yet.
