怎样在C#中调用LabVIEW/CVI的用户界面控件？

[sslisaCandy]

您好！请问我想在C#中调用CVI的CWGraph控件，用来绘制通讯传过来的数据波形，我的步骤是新建一个工程，新建一个uir文件。然后添加自己设置好的CWGraph控件之后，生成全部代码，新建一个.c文件，加入dllmain函数。然后把main函数改成if ((panelHandle = LoadPanelEx(0, "Main.uir",PANEL,__CVIUserHInst)) < 0)，将工程输出设置为dll。

C#的开发平台是VS2010   WINFORM。

但是调用后，运行时报"试图加载格式不正确的程序“的错误 。问题有可能出在哪个方面呢？非常感谢您的解答。

int __stdcall DllMain (HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved)
{
switch (fdwReason)
{
case DLL_PROCESS_ATTACH:
if (InitCVIRTE (hinstDLL, 0, 0) == 0)
return 0; /* out of memory */
break;
case DLL_PROCESS_DETACH:
CloseCVIRTE ();
break;
}

return 1;
}

int __stdcall DllEntryPoint (HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved)
{
/* Included for compatibility with Borland */

return DllMain (hinstDLL, fdwReason, lpvReserved);
}

是否需要写InitCVIRTE 和CloseCVIRTE 函数内容？

Your dll main looks ok.

Did you remember to check "enable LoadExternalModule" on the target settings window?

You can always attach your dll to the C# application to run an debug.
