Initialization interface has been an error, find the reasons for a long time all don't understand, hope to have help to see what's going on, the code is as follows:

 using System; 
Using System. Collections. Generic; 
Using System.Com ponentModel; 
Using System. The Data; 
Using System. Drawing; 
Using System. Linq; 
using System.Text; 
Using System. Windows. Forms; 
Using System. The Runtime. InteropServices; 
Using yh_interface; 
Using System. The Reflection; 


The namespace YH 
{
Public partial class ff: Form 
{

//System. The Type yh=the GetTypeFromProgID (" YinHai. SCMYInterface "); 


//Object yhObject; 





Public ff () 
{
InitializeComponent(); 
} 
//business interface function 
Public static short li_appcode=1; 
Public static string ls_appmsg=""; 
Public static string a=""; 

//initialize interface 


Public static bool JK_Init () 
{
COClass_n_yh_interface YH=new COClass_n_yh_interface (); 
//System. The Type yh=the GetTypeFromProgID (" YinHai. SCMYInterface "); 


YH. Yh_interface_init (a, li_appcode, ls_appmsg); 

If (ff) li_appcode & gt;=0) 
{
return true; 
} 
return false; 
} 
# region initialization 
Private void button1_Click (object sender, EventArgs e) 
{
JK_Init (); 
} 
# endregion

COClass_n_yh_interface content is what? Is his own definition or reference?

CodePudding user response:

references on the 1st floor buses meet response:

COClass_n_yh_interface content is what? Is his own definition or reference?

Is referenced, the content inside don't know, should not content of the problem, as a parameter

CodePudding user response:

If the DLL is written in c #, you use Windows's own IL disassembler see inside the constructor method

CodePudding user response:

To the administrator mode vs try... This cannot be created are generally access error

CodePudding user response:

You copy all the files under yinhaisoft to the debug directory is ok, but you will be another error below:

Then there is no then, I was stuck in here not bottom go to, don't know you solve have no?

CodePudding user response:

DLLS are need to debug or folder with the environment, but COClass_n_yh_interface. The init is probably a pointer, the parameter types may be wrong, this should have the document to you, or you won't let you do

CodePudding user response:

Projects to use x86 compiler, using anyCPU has the problem, that's what I was solved

CodePudding user response:

Compilation, into a 32-bit CPU, try it
