用 c++/c 如何向数据库中，插入图片，。

例如： 图形文件 c:\picture.bmp , 把它插入数据库，如何 做？
我用 java 和 delphi ,已经解决了！
想知道，用vc, unix c, vb 如何实现！

不是我，不给分，我的太少了

int main()
{
(80==500) ? GiveYouADetailedAnswer() : GiveYouABriefAnswer();
}

void GiveYouAnDetailedAnswer()
{
// This function is omitted due to the compiling optimization
}

void GiveYouABriefAnswer()
{
OleInitialize(0);
HBITMAP hBmp=LoadBitmap(...); // LoadImage
PICTDESC pd;
memset(&pd, 0, sizeof(pd));
pd.cbSizeOfStruct=sizeof(pd);
pd.picType = PICTYPE_BITMAP;
pd.hbitmap = hBmp;
IPicture * piPict;
OleCreatePictureIndirect(&pd, IID_IPicture, TRUE, &piPict);
// Obtain IStream point from a BLOB field
IStream pStream;
//... SomeObj->QueryInterface(IID_IStream, &pStream);
piPict->SaveAsFile(pStream, TRUE, NULL);

vc中，向access插入位图：
在 CdaoRecordset 派 生 类 的 对 象 中，VC 自 动 为ACCESS 的“OLE 对 象” 域 生 成 一 个CLongBinary 对 象。 该 类 虽 然 较 简 单， 在 程 序 里 却 需 要 使 用 全 局 函 数GlobalAlloc() 和GlobalFree() 处 理 与 它 的 内 存 句 柄m_hData 有 关 操 作， 访 问 数 据 前 后 要 调 用GlobalLock() 和GlobalUnlock()， 而 且 还 要 给 它 的m_dwDataLength 赋 值， 使 用 起 来 相 对 复 杂， 所 以 一 般 推 荐 使 用CByteArray 类。 这 只 需 要 在CdaoRecordset 派 生 类 对 象 的 数 据 说 明 里 修 改 一 下， 并 把DoFieldExchange() 里 的DFX_LongBinary() 改 成DFX_Binary() 即 可。

我还以为真的是什么要命的东东?
大哥，你也太小题大作了吧!
开个玩笑，：)
