跪求这段程序错在哪？

是虚拟打印的程序，转换完的图片我希望放到d:\\sample中。在OEMStartPage函数中：
BOOL APIENTRY
OEMStartPage(
    SURFOBJ    *pso)
{
    TERSE(UNITEXT(\"OEMStartPage() entry.\\r\\n\"));


    PDEVOBJ  pdevobj = (PDEVOBJ)pso->dhpdev;
    POEMPDEV pOemPDEV = (POEMPDEV)pdevobj->pdevOEM;
    PDEVMODE pPubDev = (PDEVMODE)pdevobj->pPublicDM;
POEMDEV  pOemDev = (POEMDEV)pdevobj->pOEMDM;


    // increment page number 页数增加
    pOemPDEV->PageNum++;

   if(!pOemPDEV->bAppendPageNum)
     pOemPDEV->szPreviewFileName=\"D:\\sample\\1.bmp\"; //文件名要放的地方
if(lstrlen(pOemPDEV->szPreviewFileName))//文件名长度不为空
{
TCHAR szBuffer[MAX_PATH] = {0};
PTSTR pFilePart = NULL;

// 得到全部路径的名字
     GetFullPathName(pOemPDEV->szPreviewFileName, MAX_PATH, szBuffer, &pFilePart);

// create temp file
HANDLE hFile = CreateFile(szBuffer, GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
if(hFile == INVALID_HANDLE_VALUE)
        {
return FALSE;
        }
else
{
            // close & delete file
CloseHandle(hFile);
DeleteFile(szBuffer);
}

// update szPreviewFileName
lstrcpy(pOemPDEV->szPreviewFileName, szBuffer);
}
else
return FALSE;

}

      
// set resolution 设置精度
if(pPubDev->dmOrientation == DMORIENT_PORTRAIT)
{
pOemPDEV->DIBInfo.XPelsPerMeter = pPubDev->dmPrintQuality * 10000 / 254;
pOemPDEV->DIBInfo.YPelsPerMeter = pPubDev->dmYResolution * 10000 / 254;
}
else
{
pOemPDEV->DIBInfo.XPelsPerMeter = pPubDev->dmYResolution * 10000 / 254;
pOemPDEV->DIBInfo.YPelsPerMeter = pPubDev->dmPrintQuality * 10000 / 254;
}

// calculate approximate page height 计算纸的高度
if(pPubDev->dmOrientation == DMORIENT_PORTRAIT)
pOemPDEV->approHeight = pPubDev->dmPaperLength * pPubDev->dmYResolution / 254 + 10;
else
pOemPDEV->approHeight = pPubDev->dmPaperWidth * pPubDev->dmPrintQuality / 254 + 10;

// allocate memory for scanline pointer array 分配扫描行数的内存空间
if(!(pOemPDEV->DIBInfo.pScans = (PSCANLINEPTR)HeapAlloc(pOemPDEV->hHeap, HEAP_ZERO_MEMORY,
pOemPDEV->approHeight * sizeof(SCANLINEPTR))))
{
WARNING(UNITEXT(\"    error(%d) occured while allocating memory for pScans!\\r\\n\"), GetLastError());
return FALSE;
}


    // turn around to call Unidrv 进入驱动
    return (((PFN_DrvStartPage)(pOemPDEV->pfnUnidrv[UD_DrvStartPage]))(pso));
}

编译完了出的错是：
error c2220:warning treated as error - no object file generated
error c4129:\'s\':unrecognized character escaple sequence
error c2440:\'=\':cannot convert from \'char[141]\'to \'TCHART[260]\'
这些错都在 pOemPDEV->szPreviewFileName=\"D:\\sample\\1.bmp\"; //文件名要放的地方地方
错在哪？？

反斜杠 \ 放在引号中要用 \\
