ComboBox 의 Item과 List 구성하기

연관글 보기
 2010/05/13 - [개발언어/C++] - ComboBox의 GetCurSel의 ItemDate를 가져와서 SQL Querey 하기

ComboBox의 Item과 List를 DB를 통해서 구성합니다.

CComboBox::SetItemDataPtr

int SetItemDataPtr( int nIndex, void* pData );

Return Value

CB_ERR if an error occurs.

Parameters

nIndex

Contains a zero-based index to the item.

pData

Contains the pointer to associate with the item.

Remarks

Sets the 32-bit value associated with the specified item in a combo box to be the specified pointer (void*). This pointer remains valid for the life of the combo box, even though the item’s relative position within the combo box might change as items are added or removed. Hence, the item’s index within the box can change, but the pointer remains reliable.

Example

// The pointer to my combo box.
extern CComboBox* pmyComboBox;

// Set the data pointer of each item to be NULL.
for (int i=0;i < pmyComboBox->GetCount();i++)
{
   pmyComboBox->SetItemDataPtr(i, NULL);
}
