C # calling external files

Unfortunately, the software "Data Mining-overlapping clustering" that I used to help my teacher in the past really feels good and has patent rights .. O (zookeeper) O .. Unfortunately, after a long time, I accidentally restored the system and lost it... So it's called regret .. So .. It is necessary to record, think, and summarize a project online ..

I had nothing to do over the past two days and made a desktop software. Some external programs are called. Summary:

1. C # Call the EXE file

System. Diagnostics. process. Start ("calc.exe ");
// This will enable it. Of course, you can handle Fault Tolerance later.

String _ Path = application. startuppath; above is the path to the program you are currently executing
Input. String dfgdf = _ path + "\ general.txt"; with "_ path", you can process the entire string.

2. How to call an external dos program in C?

Use the process object:
System. Diagnostics. PROCESS p = new system. Diagnostics. Process ();
P. startinfo. filename = "arj.exe"; // name of the program to be started
P. startinfo. Arguments = "-x sourcefile. ARJ c: \ Temp"; // startup Parameter
P. Start (); // start
If (P. hasexisted) // determines whether the running is completed.
P. Kill ();

3. Read the word content and display it in the control.

Add a button and a RichTextBox to form, and add a click event to the button.
Private void button#click (Object sender, eventargs E)
{
Object filepath = "d :\\ debugtest.doc ";
Openword (filepath );
}
// Put the word
Extract the document content and put it in RichTextBox.
Private void openword (Object Spath)
{
Object File = Spath;
Object nullobj = system. reflection. Missing. value;
Word. document Doc = mywordapp. documents. open (ref file, ref nullobj, ref upload, ref nullobj, ref nullobj, ref nullobj, ref nullobj );
Doc. activewindow. selection. wholestory ();
Doc. activewindow. selection. Copy ();
Idataobject DATA = clipboard. getdataobject ();
This. richtextbox1.text = data. getdata (dataformats. Text). tostring ();
Doc. Close (ref nullobj, ref nullobj, ref nullobj );
}

4. C # load the flash Control

For example, we will consider how to embed flash into the winform program. In Visual Studio 2010, there is a default unenabled component, Shockwave Flash Object, which can load the Flash program, to enable Shockwave Flash Object, open the toolbox in the upper left corner, right-click the toolbox, select the Add tab, name it AAA, right-click the AAA tab, and select "select item ", you can open the "select toolbox items" dialog box, click "COM components", and drag the scroll bar to the bottom. You will see the Shockwave Flash Object component, select it, and click OK ,:
 
At this point, the Shockwave Flash Object component has been added. This component is displayed on the AAA tab of the toolkit. Then, drag the component into the winform design view and set the size to 258x192, drag a button control and a label control in the public control tab of the toolkit, and add the click event processing function to the button, such:

// Each time Flash calls a function in C #, there is an event response in C #, which is received by axshockwaveflash1.
 
Axshockwaveflash1.flashcall + = new axshockwaveflashobjects. _ ishockwaveflashevents_flashcalleventhandler (axshockwaveflash1_flashcall );
