Can you read what you have posted?
I can't. :eek::sick:

Please, post good readable, formatted code snippet. Use Code tags.

Code:

---


class IEHeaderCtrl : public CHeaderCtrl
{
public:
    IEHeaderCtrl();

protected:
    afx_msg virtual void DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct);

    DECLARE_MESSAGE_MAP()
}

---

Code for IEHeaderCtrl.cpp

Code:

---

BEGIN_MESSAGE_MAP(IEHeaderCtrl, CHeaderCtrl)
END_MESSAGE_MAP

void IEHeaderCtrl::DawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{
    HDITEM hdi;
    CBrush brush(RGB(255, 0, 0));
    CString csBuffer;
    CRect rectFrame(lpDrawItemStruct->rcItem);
    ZeroMemory(&hdi, sizeof(HDITEM));

    hdi.mask = HDI_TEXT;

    LPTSTR pBuf= csBuffer.GetBufferSetLength(MAX_PATH);

    hdi.mask = HDI_TEXT;
    hdi.pszText = pBuf;
    hdi.cchTextMax = MAX_PATH;
    GetItem(lpDrawItemStruct->itemID, &hdi);
    csBuffer.ReleaseBuffer();

    CDC *pDC = CDC::FromHandle(lpDrawItemStruct->hDC);

    pDC->FillRect(rectFrame, &brush);
    pDC->SetTextColor(RGB(255, 255, 255));
    pDC->SetBkMode(TRANSPARENT);
    pDC->DrawText(csBuffer, &lpDrawItemStruct->rcItem, DT_LEFT | DT_SINGLELINE | DT_VCENTER);
    brush.Detach();
}

code for Myformview.cpp where my listctrl is embedded:

Code:

---

void MyFormView :: OnInitiUpdate()
{
    IEHeaderCtrl m_HeaderCtrl;
    CHeaderCtrl* pHeader = NULL;

    pHeader=m_List.GetHeaderCtrl();
    VERIFY(m_HeaderCtrl.SubclassWindow(pHeader->m_hWnd));       

    HDITEM hdItem;
 
    hdItem.mask = HDI_FORMAT;
}

Please, post your real code that compiles! not just a pseudo code.
And use the proper code indentations!

This is a real code and compiling at my end..

Then where and how is this method

Code:

---

void IEHeaderCtrl::
DawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)

---

declared?

See this, although already posted above..

Code:

---

class IEHeaderCtrl : public CHeaderCtrl
{
public:
    IEHeaderCtrl();

protected:
    afx_msg virtual void DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct);
    DECLARE_MESSAGE_MAP()
}

Well, there is

Code:

---

...
afx_msg virtual void DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct);
...

---

, not the

Code:

---

DawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)

---

Not getting what else you want.see the code below(already posted) which is having definition of DrawItem

Code:

---

BEGIN_MESSAGE_MAP(IEHeaderCtrl, CHeaderCtrl)
END_MESSAGE_MAP

void IEHeaderCtrl::DawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{
    HDITEM hdi;
    CBrush brush(RGB(255, 0, 0));
    CString csBuffer;
    CRect rectFrame(lpDrawItemStruct->rcItem);

    ZeroMemory(&hdi, sizeof(HDITEM));
    hdi.mask = HDI_TEXT;

    LPTSTR pBuf= csBuffer.GetBufferSetLength(MAX_PATH);

    hdi.mask = HDI_TEXT;
    hdi.pszText = pBuf;
    hdi.cchTextMax = MAX_PATH;
    GetItem(lpDrawItemStruct->itemID, &hdi);
    csBuffer.ReleaseBuffer();

    CDC *pDC = CDC::FromHandle(lpDrawItemStruct->hDC);

    pDC->FillRect(rectFrame, &brush);
    pDC->SetTextColor(RGB(255, 255, 255));
    pDC->SetBkMode(TRANSPARENT);
    pDC->DrawText(csBuffer, &lpDrawItemStruct->rcItem, DT_LEFT | DT_SINGLELINE | DT_VCENTER);
    brush.Detach();
}

There is no "definition of DrawItem".
There is a definition of DawItem. :rolleyes:

Oohhh Victor.i spelled it wrong here but at my wnd its DrawItem only
.Sorry ,plz assume it as DrawItem and tell the solution

Again: post your real code.
Why don't you want just copy/paste the code from your IDE?
Why do you ignore code indentation (or you remove it before sending a post?)

Code tags and formatting please. That mess is unreadable.

Did you debug your code? Is this DawItem (or DrawItem) called?

And BTW, do you set the ownerdraw flag to the header control items? See the Owner-Drawn Header Controls section in MSDN

Resolved..Thankyou
