CVI 调用ACtiveX控件出现错误

作者:互联网

利用CVI 做工程,三级窗体包含日期activeX控件,在win10下运行报如下错误。

后在main.c 中加上这个

 if (InitCVIRTE (0, argv, 0) == 0)
  return -1;
 
 CA_InitActiveXThreadStyleForCurrentThread (0,  COINIT_APARTMENTTHREADED );

这样解决问题。

Q:ActiveX controls cannot be created in a thread whose concurrency model is multithread apartment (MTA)

A:The fix to this issue is to call CA_InitActiveXThreadStyleForCurrentThread prior to calling NiScope_Init.  The explanation of this is that the ActiveX controls need to run with the apartment-threading-model (STA).  When the CVI run-time encounters an ActiveX control it will initialize the thread to STA.  What is happening is that NiScope_Init is probably initializing this to a multi-thread-apartment(MTA) first, so it is running into a conflict when the CVI run-time tries to run it on STA since its already initialized on MTA
