这里居然无人呀，我的问题怎么办呀

  在delphi中如何绑定ado数据源呀，那个能帮助我呀，我们可是个论坛呀，我自己在这里怎么论呀

论坛里发过不少有关数据绑定的贴，我想你不会就知道等别人答案，而不去看资料吧？我们是个论坛，但并不是没资料可看，有些问题从前讨论过，你可以看看。的确这里人气还不够，很欢迎你来这里讨论，只是我觉得学习方法也很重要！

我是全部看了这里面的每一个问题和答案之后才提问的这个问题，你这么说，并且是这么没有礼貌的说，则么让我这个新来的会员寒心呀

怎样用miDataSetGlobalHandle来实现数据的绑定


CMapXBindLayer bLayer;
CMapXFields flds;

bLayer.CreateDispatch(bLayer.GetClsid());
flds.CreateDispatch(flds.GetClsid());

//Our source data in the correct tab-delimited form.
//In practice, this could come from a text file or some
//other source.
const char* tabifiedData =
"\"Cust1\"\t\"Loc1\"\t-72.40\t42.22\r\n"
"\"Cust2\"\t\"Loc2\"\t-75.40\t40.48\r\n"
"\"Cust3\"\t\"Loc3\"\t-76.40\t38.02\r\n";

bLayer.SetLayerName("Customer");
bLayer.SetRefColumn1(3);
bLayer.SetRefColumn2(4);
bLayer.SetLayerType(miBindLayerTypeXY);

flds.Add(1, "Customer");
flds.Add(2, "Location");
flds.Add(3, "X");
flds.Add(4, "Y");

//The global handle which will contain the actual data.
HGLOBAL hGlobalData=NULL;
//This temporarily points to the location of the locked
//handle's data

char* pHandleData=NULL;
COleVariant SourceData;

//Allocate space for the handle's data and copy the source
//data into it
hGlobalData = GlobalAlloc(GMEM_MOVEABLE, strlen(tabifiedData)+1);
pHandleData = (char*)GlobalLock(hGlobalData);
strcpy(pHandleData, tabifiedData);
GlobalUnlock(hGlobalData);
pHandleData = NULL;

//Point the SourceData variant at the global handle
SourceData.vt = VT_I4;
SourceData.lVal = (long)hGlobalData;

try {
//Now add the Dataset to the Datasets collection
COleVariant bindVt, fldsVt;
COptionalVariant optVt;

fldsVt.vt = VT_DISPATCH;
fldsVt.pdispVal = flds.m_lpDispatch;

bindVt.vt = VT_DISPATCH;
bindVt.pdispVal = bLayer.m_lpDispatch;

CMapXDataset ds = m_ctrlMapX.GetDatasets().Add(miDataSetGlobalHandle, SourceData, COleVariant("My Dataset"), COleVariant(1l), optVt, bindVt, fldsVt, optVt);

//Create a simple Theme from the data
ds.GetThemes().Add(COptionalVariant(), COptionalVariant(), COptionalVariant());
}
catch (COleDispatchException *e) {
e->ReportError();
e->Delete();
}
catch (COleException *e) {
e->ReportError();
e->Delete();
}

这个问题好象已经讨论了n遍了哦：）
现在把他固定
好的不？

呵呵，不好意思，我是个菜鸟，没有发现：）
