C # development of Flash programs

You can try the following keywords to search for other materials Keywords (C #, Flash, winform, Flash Embedded C #, flash development UI) To embed flash in the C # winform program, the OCX control of Flash is directly referenced. Then you need to use the "COM component" Shockwave Flash Object. However, the "flash. ocx" control cannot be directly found in the "COM components" window .. You need to manually add the toolkit, select "Tools"> "Custom toolkit" from the menu, open the "Custom toolkit" window, and click "Browse" in "COM components, then select "C: // WINNT (Windows) // system32 // macromedflashswflash. OCX control. After confirmation, you can see two new controls in the toolbox: "flashfactory" and "shockwaveflash ". Add control note I have installed both the "XP system" and flash 8 and Flash 9. shockwaveflash is under the "C:/Windows/system32/macromed/flash/" Directory (I used "flash9d. OCX ") When you find that your shockwaveflash program prompts you "not registered", you may lack the "Microsoft Multimedia Control, version 6.0" control. You can add this control to the "toolbox" first. This control is available in "C:/Windows/system32/mci32.ocx". If not, you can download Now we can embed a flash into the program. Movie: storage address of Flash Embedmovie: whether to embed data into program resources. After the initializecomponent (); control is loaded, flashbox_ui.movie = application. startuppath + "// flashplayer.swf"; connects to the embedded SWF File The form1.cs file is as follows: Using system; Using system. Collections. Generic; Using system. componentmodel; Using system. Data; Using system. drawing; Using system. text; Using system. Windows. forms; Namespace flashshell2 { Public partial class form1: Form { Public form1 () { Initializecomponent (); Flashbox_ui.movie = application. startuppath + "// flashplayer.swf "; } } } --------------------------------- Flash C # communication -------------------------------------- In flash, you can use the fscommand function to communicate with the hosting app. This function has two parameters: Command: command name Parameters: Parameters Example: On (Press ){ Fscommand ("circule", "green "); } In C #, process the fscommand event of the Flash Object. If the eventargs of the event processing function is E, the corresponding relationship is as follows: E. Command-> command parameter when fscommand is called in Flash; E. ARGs-> the arguments parameter when fscommand is called in flash. The setvariable method is used to transmit values to flash in C: Axshockwaveflash1.setvariable ("variablename", "valueasstring "); Corresponding, there is a getvariable method to get the variable value in flash. Only one fscommand parameter can be passed, so its function has some limitations. When you need to pass multiple parameters, the caller needs to concatenate the parameter values with strings and then unbind them again. This method makes complex value passing ugly. However, in addition to fscommand, we also have another way to communicate with flash by Using Flash Player 8 External API. Http://www.codeproject.com/cs/media/flashexternalapi.asp) The external API can be used to implement two-way calls of ActionScript and C. The advantage is that the parameters and returned values are passed through an XML document each time you call them, which is much better than the fscommand function. Of course, in C #, we also need to declare the ing between external function implementations. Code snippet: Declare the callback function provided to the hosting application in Flash ActionScript: Import flash. External. externalinterface; Externalinterface. addcallback ("loadandplayvideo", null, loadandplayvideo ); When flash is called in C: Flashplayer. callfunction ("<invoke" + "Name =/" loadandplayvideo/"returntype =/" XML/"> <Arguments> <string> "+ filedialog. filename + "</String> </arguments> </invoke> "); Call the C # function in ActionScript: Externalinterface. Call ("resizeplayer ", Videoplayer. Metadata. Width, videoplayer. Metadata. Height ); Declare the function called by flash in C: Flashplayer. flashcall + = New _ ishockwaveflashevents_flashcalleventhandler (flashplayer_flashcall ); Here, we can see that the communication between C # And flash is quite convenient.
