  findViewById (R.id.myButton). setOnClickListener (new View.OnClickListener () (public void onClick (View v) (/ / Do stuff)));

Add a Listener using the above method has a drawback is that if control is too large, Listener will increase the number, so the following tips can be used to reduce the number of Listener:

1

  View.OnClickListener handler = View.OnClickListener () (public void onClick (View v) (switch (v.getId ()) (case R.id.Button01: / / doStuff break; case R.id.Button02: / / doStuff break;))) findViewById (R.id.myButton). setOnClickListener (handler); findViewById (R.id.myOtherButton). setOnClickListener (handler);

The Android1.6 inside, add the Listener's work has become fairly simple (feeling more like doing web programming!), Concrete steps are as follows:

1. First, the definition in the layout inside the Button and specify the response Listener

1

  <? xml version = "1.0" encoding = "utf-8"?> <LinearLayout xmlns: android = "http://schemas.android.com/apk/res/android" android: orientation = "vertical" android: layout_width = "fill_parent" android: layout_height = "fill_parent"> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> <Button android: text = "Button01" android : id = "@ + id/Button01" android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: onClick = "myClickHandler01" /> <Button android: text = "Button02" android: id = "@ + id / Button02 "android: layout_width =" wrap_content "android: layout_height =" wrap_content "android: onClick =" myClickHandler02 "/> <TextView android: layout_width =" fill_parent "android: layout_height =" wrap_content "android: text =" @ string / hello "/> </ LinearLayout>

These two lines of which the following are new features:

android: onClick = "myClickHandler01"

android: onClick = "myClickHandler02"

2. In the event inside the definition of public methods myClickHandler01, and myClickHandler02 (Note that these two methods must have a View of the shape parameter).

1

  package com.ray.test; import android.app.Activity; import android.os.Bundle; import android.view.View; public class TestOnClickListener extends Activity (@ Override public void onCreate (Bundle savedInstanceState) (super.onCreate (savedInstanceState) ; setContentView (R.layout.main);) public void myClickHandler01 (View target) (setTitle ( "myClickHandler01");) public void myClickHandler02 (View target) (setTitle ( "myClickHandler02");))

Of course, you can also use this wording:

The two buttons set to the same Listener

android: onClick = "myClickHandler"

android: onClick = "myClickHandler"

  package com.ray.test; import android.app.Activity; import android.os.Bundle; import android.view.View; public class TestOnClickListener extends Activity (@ Override public void onCreate (Bundle savedInstanceState) (super.onCreate (savedInstanceState) ; setContentView (R.layout.main);) public void myClickHandler (View target) (switch (target.getId ()) (case R.id.Button01: setTitle ( "myClickHandler01"); break; case R.id.Button02 : setTitle ( "myClickHandler02"); break;)))

8. Get Item Infomation

TCHAR szBuf[1024];
LVITEM lvi;
lvi.iItem = nItemIndex;
lvi.iSubItem = 0;
lvi.mask = LVIF_TEXT;
lvi.pszText = szBuf;
lvi.cchTextMax = 1024;
m_list.GetItem(&lvi);

More infomation: Q173242: Use Masks to Set/Get Item States in CListCtrl

9. Get the header titile of CListCtrl

LVCOLUMN lvcol;
char  str[256];
int   nColNum;
CString  strColumnName[MAX_COL];
nColNum = 0;
lvcol.mask = LVCF_TEXT;
lvcol.pszText = str;
lvcol.cchTextMax = 256;
while(m_list.GetColumn(nColNum, &lvcol))
{
    strColumnName[nColNum] = lvcol.pszText;
    nColNum++;
}

10. Scoll the scollbar to ensure item visible

m_list.EnsureVisible(i, FALSE);

11. Get the column count of CListCtrl

int nHeadNum = m_list.GetHeaderCtrl()->GetItemCount();

12. Delete all the columns

Method 1:

while ( m_list.DeleteColumn (0));

Once you delete the first column, the next columns will move above.

Method 2:

for (int i=nColumns-1; i>=0; i–)

          m_list.DeleteColumn (i);

13. Get the row and column index of the clicked item

Method 1:

void CTestDlg::OnClickList1(NMHDR* pNMHDR, LRESULT* pResult)
{
   DWORD dwPos = GetMessagePos();
   CPoint point( LOWORD(dwPos), HIWORD(dwPos) );
   m_list.ScreenToClient(&point);
   LVHITTESTINFO lvinfo;
   lvinfo.pt = point;
   lvinfo.flags = LVHT_ABOVE;
   int nItem = m_list.SubItemHitTest(&lvinfo);
   if(nItem != -1)
   {
        CString strtemp;
        strtemp.Format(“You clicked row %d column %d”, lvinfo.iItem, lvinfo.iSubItem);
        AfxMessageBox(strtemp);
   }
}

Method 2:

void CTestDlg::OnClickList1(NMHDR* pNMHDR, LRESULT* pResult)
{
   NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
   if(pNMListView->iItem != -1)
   {
        CString strtemp;
        strtemp.Format(“You clicked row %d column %d”,
                        pNMListView->iItem, pNMListView->iSubItem);
        AfxMessageBox(strtemp);
   }
}

14. Check if you clicked on the checkbox

void CTestDlg::OnClickList1(NMHDR* pNMHDR, LRESULT* pResult)
{
   DWORD dwPos = GetMessagePos();
   CPoint point( LOWORD(dwPos), HIWORD(dwPos) );
   m_list.ScreenToClient(&point);
   LVHITTESTINFO lvinfo;
   lvinfo.pt = point;
   lvinfo.flags = LVHT_ABOVE;
   UINT nFlag;
   int nItem = m_list.HitTest(point, &nFlag);
   if(nFlag == LVHT_ONITEMSTATEICON)
   {
        AfxMessageBox(“clicked on the checkbox”);
   }
   *pResult = 0;
}

15. pop up menu when right mouse button clicked

void CTestDlg::OnRclickList1(NMHDR* pNMHDR, LRESULT* pResult)
{
    NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
    if(pNMListView->iItem != -1)
    {
        DWORD dwPos = GetMessagePos();
        CPoint point( LOWORD(dwPos), HIWORD(dwPos) );
        CMenu menu;
        VERIFY( menu.LoadMenu( IDR_MENU1 ) );
        CMenu* popup = menu.GetSubMenu(0);
        ASSERT( popup != NULL );
        popup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y, this );
    }
    *pResult = 0;
}

1. CListCtrl style

       LVS_ICON: for each item displayed great icon

       LVS_SMALLICON: for each item displayed on the icon

       LVS_LIST: a show with a small icon on the item

       LVS_REPORT: Show item details

       You can inspect the Windows Explorer, just like “View” tab with “icon, small icon, list details”

2. CListctrl style and expand style

LONG lStyle;
lStyle = GetWindowLong (m_list.m_hWnd, GWL_STYLE); // Get the current window style
lStyle &= ~ LVS_TYPEMASK; // Clear display
lStyle |= LVS_REPORT; // set style
SetWindowLong (m_list.m_hWnd, GWL_STYLE, lStyle); // set style
DWORD dwStyle = m_list.GetExtendedStyle ();
dwStyle |= LVS_EX_FULLROWSELECT; // highlight the selected full row
dwStyle |= LVS_EX_GRIDLINES; // grid lines (with the style of the report)
dwStyle |= LVS_EX_CHECKBOXES; // checkbox controls
m_list.SetExtendedStyle (dwStyle); // set expand style

Note: Please check MSDN for style details.

3. Insert data

m_list.InsertColumn (0, “ID”, LVCFMT_LEFT, 40); // insert column
m_list.InsertColumn (1, “NAME”, LVCFMT_LEFT, 50);
int nRow = m_list.InsertItem (0, “11 “);// Row
m_list.SetItemText (nRow, 1, “jacky “);// set of data

4. Always selected item
Check the style of Show selection always, or in the section 2  above set LVS_SHOWSELALWAYS style.

5. Check and uncheck a row

int nIndex = 0;
// Check
m_list.SetItemState (nIndex, LVIS_SELECTED | LVIS_FOCUSED, LVIS_SELECTED | LVIS_FOCUSED);
// Uncheck
m_list.SetItemState (nIndex, 0, LVIS_SELECTED | LVIS_FOCUSED);

6. Get the checkbox status of all the rows

m_list.SetExtendedStyle(LVS_EX_CHECKBOXES);
CString str;
for(int i=0; i<nRowCount;i++)
{
   if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED || m_list.GetCheck(i))
   {
        str.Format(_T(“checkbox checked in row %d”), i);
        AfxMessageBox(str);
   }
}

7. Get the selected row index

Method 1:

CString str;
for(int i=0; i<nRowCount;i++)
{
    if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED )
    {
        str.Format(_T(“ROW %d selected.”), i);
        AfxMessageBox(str);
    }
}

Method 2:

POSITION pos = m_list.GetFirstSelectedItemPosition();
if (pos == NULL)
TRACE0(“No items were selected!\n”);
else
{
    while (pos)
    {
        int nItem = m_list.GetNextSelectedItem(pos);
        TRACE1(“Item %d was selected!\n”, nItem);
        // you could do your own processing on nItem here
    }
}

The simplest way to change the row height in a CListCtrl is:

Display an icon with the desired height.

All other ways that I know of require significant programming (such as owner draw, which is often too much work).

fatal error RC1004: unexpected end of file found.

It’s a bug of the resource compiler.

The solution is adding a blank line or two to the end of the file  and build again.

So, how to get the privileges to your utility through programatically at the time of setup?

Here is the solution provided by David Lowndes:

To achieving this privilege, you need to add a manifest to your application that specifies a requestedExecutiionLevel of “requireAdminstrator” – whick tells Vista that it needs to run elevated.

In gina, the system will list the domain name of the current system. How to get the primary domain name in your program?

From the released the Windows2000 and NT source code, you can get the code of gina. It locate on \win2k\private\windows\gina\winlogon\usrpro.c.

Here is the code:

DWORD rc;
PWSTR PrimaryDomain;

rc = NetGetJoinInformation (
NULL,
&PrimaryDomain,
&Type
);

if (rc != ERROR_SUCCESS)
{
PrimaryDomain = NULL;
}
else
{
wprintf(TEXT(“PrimaryDomain : %s\n”),PrimaryDomain);
}

The condition is only that the MessageBox window was created by MessageBoxA/MessageBoxW from the win32 api. Whether you call AfxMessageBox or CWnd::MessageBox in vc or MsgBox in vb, they finally call the ::MessageBoxA or ::MessageBoxW, so it also works.

Here is a example.

1. When some message box popped, press Ctrl+C to copy.

2. Paste in notepad, and you will see…

From MSDN:
The profiler is an analysis tool that you can use to examine the run-time behavior of your programs. By using profiler information, you can determine which sections of your code are working efficiently. The profiler can produce information showing areas of code that are not being executed or that are taking a long time to execute.

But in Visual C++ 6.0, you often found that the profile menu item is grayed. How to enable it?

To enable profile in VC 6.0, you first need to set the correct link parameter, and rebuild all the project.

Wait a minute, do you find that the profile menu item is still grayed?
OK. It’s because that you installed vc6 with one account but use it with another one. It’s mayby a bug of VC6.
But how can you to correct it? It’s easy. Just modify the entry value in the registery.
