This paper aims at introducing how the principle of currency dialog box function for windows is achieved and at discussing in detail its compiling principle through analysing GetOpenFileName function port parameter and its destination code.

Optimization of polymer injection parameters in the second reservoirs in Xingbei oil field;

Optimal selection of injection parameters for ASP flooding at initial development stage in Guanjiapu Offshore Oilfield;

Selection of injection parameters for alternative injection of gas and solution;

Then it determines the injection parameters of the polymer flooding.

RBF neural network is applied into the comprehensive state assessment of the railway bridge members successfully by its self-adaptability and study capability,and the input parameter is given,which is acquired expediently and can reflect the actual assessment of existing railway bridge members roundly and truly.

This paper presented a Back-Propagation network method(BP network),using struc- tural frequency response function as the network input parameters.

According to the different observing objects, the widely used photovoltaic maximum power point tracking (MPPT) techniques can be divided to two kinds, which are based on input parameters and output parameters respectively.

By the function of the dialog box in Auto CAD R12,this paper discusses the method of program design in which the parameter input of graphical interface can be carried out in parameter draft software.
