描述:
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？？
