Re: VixCom/VIX VMWare Server Exceptions: GetErrorText and Connect

This also solved my problem with Visual C++, unfortunately not DevC++
The C code connect example
[code]
#include "stdafx.h"

#include <vix.h>

int _tmain(int argc, _TCHAR* argv[])
{
VixHandle jobHandle = VIX_INVALID_HANDLE;
VixHandle hostHandle = VIX_INVALID_HANDLE;

VixError err = VIX_OK;

jobHandle = VixHost_Connect(1,VIX_SERVICEPROVIDER_VMWARE_SERVER,NULL,0,NULL,NULL,0,VIX_INVALID_HANDLE,NULL,NULL);

err = VixJob_Wait(jobHandle,
VIX_PROPERTY_JOB_RESULT_HANDLE,
&hostHandle,
VIX_PROPERTY_NONE);

if (VIX_OK != err) {
printf("\nError: %i",err);
printf("\n%s\n",Vix_GetErrorText(err,NULL));
goto abort;
} else {
printf("connection success!\n");
}

Vix_ReleaseHandle(jobHandle);

abort:
return 0;
}

Wonderful thanks...
For anyone using the code above...
Set the version to 1 and be sure to assign the propertyIDs as an array.

eg (VB).
job = VixLibA.Connect(1, VixCOM.Constants.VIX_SERVICEPROVIDER_VMWARE_SERVER, Nothing, Nothing, Nothing, Nothing, 0, Nothing, Nothing)

Dim propertyIDS() As Object = {VixCOM.Constants.VIX_PROPERTY_JOB_RESULT_HANDLE}

Dim err = job.Wait(propertyIDS, results)

Similar to the response that my colleague gave in the thread "VixHost_Connect Problem", the issue that there is a version mismatch issue.

Error code 6 is 'not supported'.

You're having an exception when you call GetErrorText() because when Connect() failed, not all of the required libraries were loaded, so VIX is having difficulties looking up the error string. We're looking into ways to make sure that this doesn't happen in future releases.

You should be able to get this to work by explicitly passing 1 as the first argument to Connect().

Just to be clear, only functions from the version 1.0 of the VIX API are supported with VMware Server.

I would like to also mention this is a 32bit environment.
This forum needs an edit post function.

VixCom/VIX VMWare Server Exceptions: GetErrorText and Connect

zerovoid — Mon, 21 May 2007 17:39:17 GMT

This post has a few questions.

What is error code 6 when trying to connect?
I get this error returned in everything C, C#, VB, VBScript/WSH, Perl
Why am I having these exceptions in VixCom for GetErrorText?
Why do my programs crash when compiled with DevC++ and VC++2005 but run fine with VC++6 (except error 6 returned)?
Is this a bug in VixCom/Vix?
Has anyone had any luck with VixCom or Vix on VMWare Server?
If yes, can you please post your code or a link to a project source?
Language is not a problem as long as it uses VIX.
The other APIs do not support some of the functionality I am seeking.

Environment:
WinXPSP2
VMWare Server 1.0.3 (even though it has been tried on older versions and different machines)
Vix API 1.1
Tried in various languages (C#, VB, VBScript, C)
