hi,
FindFirstFile API can list the files/folders in a given folder, but I need to find out what all drives are available on the system(like C:, D:, etc) and what are the media types (like harddrive, cd-drive, usb-drive, etc). Does any one have some idea to figure this out using windows file APIs?
Thanks

Thanks for that link. GetDriveType takes the drive letter as part of the argument, and I dont know how to obtain the list of drive letters available. I looked at the volume management functions, ([^]) but this example doesnt give the drive letter information. What is a volume, and what are mount points, if I may ask?
Thanks

Hi everybody!
I'm trying to find an answer on how to render a text in OpenGL and having it always in front of every object independingly of its z value. The text is placed using glRasterPos3d()..
(I don't want to use glOrtho() because I want the text to be moved in relationship with the camera)
Thanks for every answear!

You can disable the z-buffer by calling glDisable(GL_DEPTH_TEST), render the text, and re-enable z-buffer.

I have a dialog based class named CJKDlg, with a tree control with name treeTracks.
In the JKDlg.h i have defined the following structure:
struct _itemData
{
CString strData;
};
In the OK click event i have the following handler:
void CJKDlg::OnBnClickedOk()
{
CStdioFile stdFile;
CString str;
if(! stdFile.Open("test.txt", CFile::modeRead))
{
AfxMessageBox("Cannot find initialization file", MB_OK, MB_ICONSTOP);
return;
}
TVINSERTSTRUCT tvInsert;
tvInsert.hParent = NULL;
tvInsert.hInsertAfter = NULL;
tvInsert.item.mask = TVIF_TEXT;
HTREEITEM hAlbum, hItem;
char ch;
CString albumTitle, trackTitle, trackPath;
_itemData* pItemData = new _itemData();
while(stdFile.ReadString(str))
{
ch = str.GetAt(0);
if(ch=='$')
{
albumTitle = str.Right(str.GetLength()-1);
tvInsert.item.pszText = albumTitle.GetBuffer(albumTitle.GetLength());
hAlbum = m_treeTracks.InsertItem(&tvInsert);
pItemData->strData = "OK";
m_treeTracks.SetItemData(hAlbum, DWORD(pItemData));
}
}
delete pItemData;
}
In last a double-click event handler for the tree control:
void CJKDlg::OnNMDblclkTreeTracks(NMHDR *pNMHDR, LRESULT *pResult)
{
HTREEITEM hItem = m_treeTracks.GetSelectedItem();
ASSERT(hItem);
_itemData* pItemData = new _itemData();
pItemData = (_itemData *)m_treeTracks.GetItemData(hItem);
if(pItemData)
{
TRACE1("%s\n", pItemData->strData);
}
delete pItemData;
*pResult = 0;
}
The TRACE macro dose not display the "OK" string. Instead in the output window a white space displayed.
Can anyone help me with this please?

You are inserting the same pItemData for each node in the tree. Is that intentional?

delete pItemData;
This is why nothing shows up.

This statement is unnecessary in OnNMDblclkTreeTracks() . Memory was allocated in OnBnClickedOk() .

Daim you are right! The data is not the same for each node. I do that just to simplify the question and the code.
Thanks a lot for your time.

Hey,
i build a nice custom control (::from CWnd). It works perfect on dialogs but can't print it.
I tried to create the control in my CView::OnPrint function --> Success.
But I never come to my OnPaint function. How can I print my control? Do I have to implement a special function with a parameter-handle to my printing DC?

If given a region (could be CRgn or even just an area described by a CRect), is there a way to check if that region only contains background color (nothing really drawn in there, i.e., no characters, dots, etc)? The simplist way I could think is looping through the region and getting each pixel via the CDC::GetPixel () method, and checking it against the background color. I am basically looking for a way to determine if something is drawn in a specific area.
I was hoping if there was a more "elegant" solution. Searches both here and on the 'Net as a whole seemed to turn up nothing regarding this.
Thanks

I want to make a menu item is name "Printing " where there are many lists as item. And when I click on one item (like list of food) this list is printed
Thanks

Look for:
StartDoc()
StartPage()
TextOut()
EndPage()
EndDoc() You'll likely need others, but these are a minimum.
