I am using the zoom\_sdk\_dotnet\_wrap.dll with the the Custom UI mode.  
It is returned SDKERR\_INVALID\_PARAMETER when I call ICustomizedAnnotationObj.SaveSnapshot() , which is descripted as  
“If the specified path is wrong, the SDKERR\_INVALID\_PARAMETER will be returned.” in the windows SDK.  
The path value in my project is “D:\”  
I just want to know why the error returned and what is the correct format of the path value?

Here is my steps:  
**1.** I changed the parameter type of path to String^ in the zoom\_sdk\_dotnet\_wrap, which was const w\_char\* before. I have used the PlatformString2WChar() method to convert the value type to const w\_char\*.  
virtual SDKError SaveSnapshot(String^ path, SDKAnnoSaveType nType)  
{  
if (m\_pSDKObj)  
{  
ZOOM\_SDK\_NAMESPACE::SDKAnnoSaveType sdk\_type = (ZOOM\_SDK\_NAMESPACE::SDKAnnoSaveType)nType;  
return (SDKError)m\_pSDKObj-\>SaveSnapshot(PlatformString2WChar(path), sdk\_type);  
}

```
	return SDKError::SDKERR_UNINITIALIZE;
}

```

**2.** In the C# program, I get an ICustomizedAnnotationObjDotNetWrap object first.  
this.mAnnotationController = CZoomSDKeDotNetWrap.Instance.GetMeetingServiceWrap()  
.GetAnnotationController().GetCustomizedAnnotationController(shareRender);

```
 if (this.mAnnotationController != null)
 {
         this.mAnnotationObj = this.mAnnotationController.CreateAnnoObj(shareRender);
 }

```

**3.** I call the Snapshot() function when user click the button.  
If(this.mAnnotationObj!=null)  
{  
var errCode = this.mAnnotationObj.SaveSnapshot(@“D:\”);  
}

Thanks.

Thanks for relpy.  
The version is 5.5.7681.0323.  
And I found out that the snapshot has been saved successfully, but the return code is SDKERR\_INVALID\_PARAMETER.  
Thanks.

Hey @VideoPro,

So the method worked correctly but still returned an error?

Thanks!

Yes, it does.  
You may check if it is a bug or not.

Thanks.

Hey @VideoPro,

Got it. Can you reproduce the issue once more and send your SDK logs to [developersupport@zoom.us](mailto:developersupport@zoom.us)? Please mention my name in the email.

Thanks!  
Michael

Hey @VideoPro,

After your application has exited gracefully, the logs will be put in %appData%/roaming/ZoomSDK.

Thanks!
