VC显示图片的问题
大家看过这段代码为，使用的时候有点问题：
if (IsIconic())
{
CPaintDC dc(this); // device context for painting
SendMessage(WM_ICONERASEBKGND, (WPARAM) dc.GetSafeHdc(), 0);
// Center icon in client rectangle
int cxIcon = GetSystemMetrics(SM_CXICON);
int cyIcon = GetSystemMetrics(SM_CYICON);
CRect rect;
GetClientRect(&rect);
int x = (rect.Width() - cxIcon + 1) / 2;
int y = (rect.Height() - cyIcon + 1) / 2;
// Draw the icon
dc.DrawIcon(x, y, m_hIcon);
}
else
{
CDialog::OnPaint();
}
CWnd *pWnd = GetDlgItem(IDC_PICTURE);
CRect rect;
pWnd->GetClientRect(&rect);
CDC *pDC = pWnd->GetDC();
IStream *pStm;
CFileStatus fstatus;
CFile file;
LONG cb;
IPicture *pPic;
CString m_sPath = "baby.jpg"; //需要显示的图片地址
if(file.Open(m_sPath,CFile::modeRead)&&file.GetStatus(m_sPath,fstatus)&& ((cb = fstatus.m_size) != -1))
{
HGLOBAL hGlobal = GlobalAlloc(GMEM_MOVEABLE, cb);
LPVOID pvData = NULL;
if (hGlobal != NULL)
{
if ((pvData = GlobalLock(hGlobal)) != NULL)
{
file.ReadHuge(pvData, cb);
GlobalUnlock(hGlobal);
CreateStreamOnHGlobal(hGlobal, TRUE, &pStm);
}
}
}
if(SUCCEEDED(OleLoadPicture(pStm,fstatus.m_size,TRUE,IID_IPicture,(LPVOID*)&pPic)))
{
OLE_XSIZE_HIMETRIC hmWidth;
OLE_YSIZE_HIMETRIC hmHeight;
pPic->get_Width(&hmWidth);
pPic->get_Height(&hmHeight);
if(FAILED(pPic->Render(*pDC,0,0,rect.Width(),rect.Height(),0,hmHeight,hmWidth,-hmHeight,NULL)))
AfxMessageBox("渲染图像失败！");
pPic->Release();
}
else
AfxMessageBox("从流中装载图像失败！");
问题就是显示图片的地址m_sPath如果使用CFileDialog选择图片，然后用GetPathName金线复制就可以正常显示，但是如果直接赋值，例如m_sPath="house.jpg"就不能显示，这到底是怎么回事啊，求解
[解决办法]
图片地址需要使用全路径(像D:\\picdir\\a.jpg这样的),用CFileDialog 得到的就是图片文件的全路径,直接赋值m_sPath="house.jpg"在默认搜索路径下通常是找不到文件的
