通过修改VCL源码实现自定义输入对话框，在BCB中有两个函数可以实现输入对话框：InputBox和InputQuery，其实InputBox也是调用了InputQuery，这个函数有几个缺点：-amend VCL source implementation-defined input dialog, the BCB has two functions can be achieved input dialog : InputBox and InputQuery, also called the InputBox InputQuery, this function has several drawbacks :

This is a photo of a general purpose timer/counter card you can wirewrap in a weekend. It plugs into your PC s ISA bus just like a sound or modem card. It gives high-resolution timing (microseconds). Because of its programmablity, it is very powerful and flexible. You can even control DC or servo motors using pulse-width modulated (PWM), or stepper motors using its square wave capabilities. The figure below is the actual output (square wave) from the 8254 card captured by an oscilloscope:
