hmm there is some problem in your code. I have modified it as follows
NMLVCUSTOMDRAW* pLVCD = reinterpret_cast<NMLVCUSTOMDRAW*>(pNMHDR);
*pResult = CDRF_DODEFAULT;
if ( CDDS_PREPAINT == pLVCD->nmcd.dwDrawStage )
{
*pResult = CDRF_NOTIFYITEMDRAW;
}
else if (pLVCD->nmcd.dwDrawStage == CDDS_ITEMPREPAINT )
{
*pResult = CDRF_NOTIFYSUBITEMDRAW;
}
else if (pLVCD->nmcd.dwDrawStage == (CDDS_ITEMPREPAINT | CDDS_SUBITEM))
{
if ( (m_nSubItemSelect == pLVCD->iSubItem) &&
((pLVCD->nmcd.uItemState &CDIS_SELECTED) == CDIS_SELECTED))
{
pLVCD->clrTextBk = RGB(0,0,255);
pLVCD->clrText = RGB(255,255,255);
}
else
{
pLVCD->clrTextBk = RGB(255,255,255);
pLVCD->clrText = RGB(0,0,0);
pLVCD->nmcd.uItemState = pLVCD->nmcd.uItemState& ~CDIS_SELECTED;
}
}

My code now looks like this:
void CIMAPIListCtrl::OnClick(NMHDR* pNMHDR, LRESULT* pResult)
{
NMLISTVIEW * pLV = reinterpret_cast<nmlistview>(pNMHDR);
LVHITTESTINFO stInfo = {0};
if(m_nSubItemSelect != -1 && m_nCurrentlySelectedItem != -1)
{
CRect rcItem;
GetItemRect(m_nCurrentlySelectedItem, rcItem, LVIR_BOUNDS);
InvalidateRect(rcItem);
}
stInfo.pt = pLV->ptAction;
SubItemHitTest( &stInfo );
int nRow = stInfo.iItem;
int nClmn = stInfo.iSubItem;
if(GetItemText(nRow,nClmn)=="") return;
if (nRow != -1)
{
if (m_nSubItemSelect != nClmn)
{
m_nSubItemSelect = nClmn;
m_nCurrentlySelectedItem = nRow;
CRect rcItem;
GetItemRect(nRow, rcItem, LVIR_BOUNDS);
InvalidateRect(rcItem);
}
}
*pResult = 0;
}
void CIMAPIListCtrl::OnCustomdraw(NMHDR* pNMHDR, LRESULT* pResult)
{
NMLVCUSTOMDRAW* pLVCD = reinterpret_cast<nmlvcustomdraw*>(pNMHDR);
*pResult = CDRF_DODEFAULT;
if ( pLVCD->nmcd.dwDrawStage == CDDS_PREPAINT )
{
*pResult = CDRF_NOTIFYITEMDRAW;
}
else if (pLVCD->nmcd.dwDrawStage == CDDS_ITEMPREPAINT)
{
*pResult = CDRF_NOTIFYSUBITEMDRAW;
}
else if (pLVCD->nmcd.dwDrawStage == (CDDS_ITEMPREPAINT | CDDS_SUBITEM))
{
if((m_nSubItemSelect == pLVCD->iSubItem) &&
(pLVCD->nmcd.uItemState & CDIS_SELECTED)==CDIS_SELECTED &&
m_nCurrentlySelectedItem == pLVCD->nmcd.dwItemSpec)
{
pLVCD->clrTextBk = RGB(0,0,255);
pLVCD->clrText = RGB(255,255,255);
}
else
{
pLVCD->clrTextBk = RGB(255,255,255);
pLVCD->clrText = RGB(0,0,0);
pLVCD->nmcd.uItemState = pLVCD->nmcd.uItemState& ~CDIS_SELECTED;
}
}
}
</nmlistview>
The problem is that for hiliting subitem I need first to click on column 0 and then subitem column to work. Exception is when clicking on first row after listctrl is populated!

I think the checking should be done in the following way...
if (nRow != -1)
{
m_nCurrentlySelectedItem = nRow;
if (m_nSubItemSelect != nClmn)
{
m_nSubItemSelect = nClmn;
m_nCurrentlySelectedItem = nRow;
CRect rcItem;
GetItemRect(nRow, rcItem, LVIR_BOUNDS);
InvalidateRect(rcItem);
}
}

Hi all,
I m using a TreeCtrl with CTreeCtrl derived class.
Here i m using a LButtonDown function for get Item Text.
void CTree::OnLButtonDown(UINT nFlags, CPoint point)<br />
{<br />
CTreeView::OnLButtonDown(nFlags, point);<br />
<br />
CTreeCtrl& tc = GetTreeCtrl();<br />
::GetCursorPos(&point);<br />
tc.ScreenToClient(&point);<br />
<br />
UINT uFlags ;<br />
HTREEITEM hItem = tc.HitTest(point, &uFlags);<br />
if ((hItem != NULL) && (TVHT_ONITEM & uFlags))<br />
{<br />
tc.Select(hItem, TVGN_CARET);<br />
}<br />
tc.SelectItem(hItem);<br />
tc.SetFocus(); <br />
CString Tree_str;<br />
Tree_str = tc.GetItemText(hItem);<br />
AfxMessageBox(Tree_str);<br />
<br />
}<br />
<br />
<br />
Here number of items are present.
if i expnd all th item the VScroll display.
if scrollbar displays and i select any item than it prompt a wrong value of item.
i think its happens becoz of position change by VScroll.
Please tell me any solution for this.
Thanks in advance.

Hi Experts,
How can I traverse System Volume Information folder?
|
|
|
|
|
You have to take ownership of the directory and its objects before you can enumerate them. That works on XP, not sure about Vista or 2003.

I don't know how to do it programmatically, try googling. From the command line you can do it like this:
cacls "[driveletter]:\system volume information" /e /g [username]:f

Do you want to create Resource only DLL??
If yes you can search CP there are good articles for the same.

Ive seen a lot of applications load icons that seem to be a higher colour rate
the standard is 32x32 16bit color
is there a way to use an icon that is 256 or truecolor
in WINAPI or MFC
cheers

LoadImage is your friend. Two of the params specify a desired width and height (though all the icons I've come across have been square, I suppose that might not be true occasionally).
HINSTANCE hInst = AfxFindResourceHandle (MAKEINTRESOURCE(IDI_MYICON), RT_ICON);
HICON hHiRes = (HICON)::LoadImage (hInst, MAKEINTRESOURCE(IDI_MYICON), IMAGE_ICON, 256, 256, LR_DEFAULTCOLOR);
There's no error handling there, but I hope that gives you the idea. The AfxFindResourceHandle is MFC only, but if you're doing raw API, then I'm sure you have a (eg) m_hInstanceResource somewhere in your code to use.
Iain.

cheers  Another question
Im using visual studio 2005, I add the icon which is bigger(64X64) in high res colour
and it says
Warning: Visual Studio Image Editors do not support 32bit color images. Your changes will be discarded when
saving the image.
Is that important or can i ignore that? I dont need to edit the icon just include it I wanna know if this is a cause that will stop the icon from loading?

You can ignore any deficiencies in the IDE, as long as the resource compiler can handle it. I doubt that it even cares about the content of the icon.
The source icon is stored in an external ico file, with just a reference in your rc file. I suspect the rc.exe treats it as an opaque blob of data. If it's bad data, LoadImage will choke at a later date.
Iain.

The Code you said worked pretty well
I used a variation through API
WNDCLASSEX wc;
....
wc.hIcon = static_cast<hicon>(LoadImage( hInstance,
MAKEINTRESOURCE(IDI_ICON1),
IMAGE_ICON,
255,
255,
LR_DEFAULTCOLOR));
........................................................................
wc.hIconSm = static_cast<hicon>(LoadImage( hInstance,
MAKEINTRESOURCE(IDI_ICON1),
IMAGE_ICON,
16,
16,
LR_DEFAULTCOLOR));
</hicon></hicon>
Also a note to be taken in this, I could only get images up to 255 to work not 256, it completly rejects the file if you have any 256 in there. Thought i might just mention that.
There is also an issue with alpha blend in Visual studio, some mentioned a way around that and i quote,
"If you have an icon with alpha blend, visual studio will get rid of it straight away, so to get around that,
-->Put the icon in your /res/ folder
-->import the file via your resource editor
-->close the file in the resource editor so its not in view
-->save the project
-->copy the .ico with alpha blend over the top of the one in your res folder
-->rebuild your application
-->and you should have alpha blend,
you will not be able to open the icon in resource editor againbecause it will get rid of the alpha blend again."
This is my findings in working on my initial question, i hope it helps anyone else looking for this.
