vss 备份初始化失败并返回代码 E_UNEXPECTED

#include "vss.h"
#include "vswriter.h"
#include <VsBackup.h>
#include <stdio.h>

#define CHECK_PRINT(result) printf("%s\n",result==S_OK?"S_OK":"error")
int main(int argc, char* argv[])
{
 BSTR xml;
 LPTSTR errorText;
 IVssBackupComponents *VssHandle;


 HRESULT  result = CreateVssBackupComponents(&VssHandle);
 CHECK_PRINT(result);
 result = VssHandle->InitializeForBackup();
 printf("unexpected%x\n",result);

 system("pause");
 return 0;
}

在上面的程序中，initializeforbackup 失败，错误代码为 E_UNEXPECTED。 VSS 服务正在运行。在事件日志中，它显示为“卷影复制服务错误：调用例程 CoCreateInstance.hr = 0x800401f0 时发生意外错误。”..InitializeForBackup 返回 S_OK 的任何解决方案吗？

原文

#include "vss.h"
#include "vswriter.h"
#include <VsBackup.h>
#include <stdio.h>

#define CHECK_PRINT(result) printf("%s\n",result==S_OK?"S_OK":"error")
int main(int argc, char* argv[])
{
 BSTR xml;
 LPTSTR errorText;
 IVssBackupComponents *VssHandle;


 HRESULT  result = CreateVssBackupComponents(&VssHandle);
 CHECK_PRINT(result);
 result = VssHandle->InitializeForBackup();
 printf("unexpected%x\n",result);

 system("pause");
 return 0;
}

in the above program intializeforbackup fails with error code E_UNEXPECTED. The VSS service is running . In the event log it shows as "Volume Shadow Copy Service error: Unexpected error calling routine CoCreateInstance. hr = 0x800401f0.".. Any solutions for the InitializeForBackup to return S_OK?

您需要使用 CoInitialize 函数初始化 COM 库。

HRESULT  result = CoInitialize(NULL);
CHECK_PRINT(result);
result = CreateVssBackupComponents(&VssHandle);
CHECK_PRINT(result);
result = VssHandle->InitializeForBackup();
CHECK_PRINT(result);

这将为您提供所有 S_OK

You need to initialize the COM library with the CoInitialize function.

HRESULT  result = CoInitialize(NULL);
CHECK_PRINT(result);
result = CreateVssBackupComponents(&VssHandle);
CHECK_PRINT(result);
result = VssHandle->InitializeForBackup();
CHECK_PRINT(result);

This will give you all S_OKs
