Test an in-process OLE server DLL by building it first as an out-of-processserver. This makes it possible to debug and test. Also, the stability ofthe entire application will be affected
The well-known Horner schema lets you calculate polynomial expressions efficiently. To calculate: A*x^N + B*x^(N-1) + . + Y*x + Z ( ^ means power ), simply write this expression
You can easily make a group of controls visible or invisible. At design time, select all controls you want tomake visible or invisible during the execution. Press F4, and assign
I often want to get to the General code section of a form quickly, either to hack module-level variables or tograb the procedure pull-down to find that function whose name
Do you sometimes need to format rounded numbers to a specific number of digits? You can accomplish thisin one step: n = 12.345Format(n, “0.00”)’returns “12.350”Format(n, “0.”)’returns “12.00”Format(0.55, “#.0”) ‘returns “.60”
If you set a form’s ControlBox property to False, the Minimize and Maximize buttons also become invisible.Suppose you want to provide functionality to the user to maximize and minimize the
