Embodiment

For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.

Embodiment mono-

Referring to Fig. 1, the embodiment of the present invention provides a kind of operation method of application program, and the method flow process is specific as follows:

101: obtain simulator primitive corresponding to application program in simulator;

Particularly, first start the application program in simulator, can when application program launching or in the process of application program operation, obtain simulator primitive corresponding to application program.

102: this simulator primitive is converted to corresponding host primitive;

For this step, before this simulator primitive is converted to corresponding host primitive, first judge whether this simulator primitive can be converted to host primitive, if can, carry out the step that this simulator primitive is converted to corresponding host primitive.The mode of judgement is for to mate this simulator primitive with primitive matching list:

If this simulator primitive and primitive matching list match, judge that this simulator primitive can be converted to host primitive;

If this simulator primitive and primitive matching list do not match, judge that this simulator primitive can not be converted to host primitive.

Wherein, the simulator primitive that can change is converted to corresponding host primitive, the concrete mode of conversion is: simulator coordinate system is converted to host coordinate system, according to this host coordinate system, the parameter in simulator primitive is modified, obtain host primitive.

103: this host primitive is sent to host, so that host is carried out this host primitive.

Further, after host is carried out this host primitive, also receive the rreturn value that host sends, this rreturn value is to receive host primitive by host, and load after host instruction set corresponding in host dynamic link library according to host primitive, carry out this host instruction set and obtain.

The method that the embodiment of the present invention provides, by starting the application program in simulator and obtaining simulator primitive, simulator primitive is converted to host primitive and sends to host, by host, carry out this host primitive, reduced the process of the conversion from simulator instruction set to host instruction set, owing to only having carried out conversion and the transmission of a primitive, thereby reduce the system loss of application program in operational process, improve the efficiency of application program operation.

Embodiment bis-

The embodiment of the present invention provides a kind of operation method of application program, in the middle of process due to application program operation, need to carry out primitive, in the system of different frameworks, it is identical having primitive greatly, or can simple conversion, as the primitive of the graphical pointv in drawing, line, rectangle etc., the order under different frameworks and parameter are likely consistent.Thus, the present invention after obtaining the simulator primitive of application program, sends to host through simple conversion by simulator, by host, carries out this host primitive, can significantly reduce the system consumption of simulator instruction set conversion.Referring to Fig. 2, method flow is specific as follows:

201: obtain simulator primitive corresponding to application program in simulator, and judge whether this simulator primitive can be converted to host primitive;

Particularly, first start the application program in simulator, can when application program launching or in the process of application program operation, obtain simulator primitive corresponding to application program.The embodiment of the present invention does not specifically limit obtaining the mode of simulator primitive, can, after simulator starts the application program in simulator, by calling simulator dynamic link library, obtain simulator primitive.Simulator gets after this simulator primitive, according to this simulator primitive and primitive matching list, judges whether this simulator primitive can be converted to host primitive:

If this simulator primitive and primitive matching list match, judge that this simulator primitive can be converted to host primitive;

If this simulator primitive and primitive matching list do not match, judge that this simulator primitive can not be converted to host primitive.

When this simulator primitive can be converted to host primitive, according to the subsequent step of the embodiment of the present invention, it is processed.

When this simulator primitive can not be converted to host primitive, in loading simulation device dynamic link library, the instruction set of correspondence, is converted to host instruction set by instruction set corresponding to this simulator primitive, by host, directly carries out this host instruction set.Because this situation is identical with simulator principle of work of the prior art, at this, no longer repeated.

203: the host primitive being converted to is sent to host;

For this step, the embodiment of the present invention does not specifically limit sending the mode of host primitive, and the above-mentioned application scenarios of enabling Windows Mobile simulator in Windows XP operating system of only take describes as example.Windows Mobile simulator drawing primitive is converted to after Windows XP host primitive, by modes such as socket or shared drives, Windows Mobile simulator sends to Windows XP operating system by drawing primitive title Ellipse and amended parameter new_hdc, new_nLeftRect, new_nTopRect, new_nRightRect, new_nBottomRect.

204: host receives the host primitive that simulator sends, and carries out this host primitive, obtains corresponding rreturn value;

Wherein, host receives after the host primitive of simulator transmission, the concrete steps of carrying out this host primitive are: according to this host primitive, call host dynamic link library and load host instruction set corresponding in host dynamic link library, be about to host primitive and be converted to corresponding host instruction set; Host is carried out this host instruction set merging and is obtained corresponding rreturn value.

With the above-mentioned application scenarios of enabling Windows Mobile simulator in Windows XP operating system, describe.Windows XP operating system receives after corresponding drawing primitive, carry out drawing primitive BOOL Ellipse (HDC new_hdc, int new_nLeftRect, int new_nTopRect, int new_nRightRect, int new_nBottomRect), obtain corresponding operation result, i.e. corresponding rreturn value.

205: the corresponding rreturn value obtaining is sent to simulator.

For this step, the embodiment of the present invention does not specifically limit sending the mode of rreturn value, and the above-mentioned application scenarios of enabling Windows Mobile simulator in Windows XP operating system of only take describes as example.Windows XP operating system obtains after corresponding rreturn value, by modes such as socket or shared drives, this rreturn value is sent to Windows Mobile simulator.

If simulator needs to proceed primitive operation after receiving rreturn value, repeat 201 to 205.
