Glad to hear it - I was just going through my emails, and had some spare time so was going to attack your code.
What was the solution in the end?
Iain.
Plz sir... CPallini CPallini abuz drugz, plz plz help urgent.

I have this in C#
[DllImport("user32")]
public static extern int SendMessage(HWND hwnd, int wMsg, int wParam, IntPtr lParam);
and I dont know what is its equivalent in C++.
|
|
|
|

It's simple to use on the c++ dont need to load any dll file or library file.
LRESULT SendMessage(
HWND hWnd,
UINT Msg,
WPARAM wParam,
LPARAM lParam );
|
|
|
|
|
it shows me an error in 'UINT' do i have to specify something else before this code?
|
|
|
|

How did you use it? can you show your code?

If you just want to call the win32 API in C++, you don't need all that garbage stuff.
The symbols for windows messages are in header files that you just include and to call SendMessage() you just do something like this...
::SendMessage(hWnd,WM_SOMEMESSAGE,wParam,lParam);

Yeah thats right.I think this little code is helpful for you and also for some messages you dont need to declare them like WM_PAINT/WM_KEYDOWN,...
class win32
{
public:
win32()
{
}
void Changecaption(HWND hwnd,UINT m_Message);
};
void win32::Changecaption(HWND hwnd,UINT m_Message)
{
SendMessageW(hwnd,m_Message,0,(WPARAM)_T("Hi how are you"));
}
win32 m_cTest;
m_cTest.Changecaption(m_hWnd,WM_SETTEXT);

Hi all,
How can I force the user to select only via dropdown, but not allowing him to edit in combobox?
Thanks,
Sunil.
Regards,
Sunil Kumar
|
|
|
|
|
Change the combobox style to CBS_DROPDOWNLIST[^]. You can change this in the resource editor. Look at the properties pane, and change the style selection.
|
|
|
|
|
open combo box properties and change style type to DropList
|
|
|
|
|
Thanks a lot,
The problem is solved.

If you want someone to even try to look at your code, read the posting guidelines at the top of the forum, They're there for a good reason.
Hint: pre tag.
Also, choosing an actual name, rather than a number helps.
Lastly, a bit more of a question please! What have you tried? Etc. Have you looked for CP articles that may help? Examples on MSDN? etc.
Iain.

I need to write a console application which would get me the list of users in a particular system and their corresponding user account privilege (Administrator, Guest, User, etc.). How could I do this ?
Thanks in advance.

Hi all,
i want to know how can i use Enter key in TreeCtrl?
i want to use this same as LButtonDown function.
i m using Lbuttondown like this.
void CMyTree::OnLButtonDown(UINT nFlags, CPoint point)
{
CTreeView::OnLButtonDown(nFlags, point);
CTreeCtrl& tc = GetTreeCtrl();
UINT uFlags = 0;
HTREEITEM hItem = tc.HitTest(point, &uFlags);
if(!hItem)
return;
tc.SelectItem(hItem);
tc.SetFocus();
CString Previous_File;
CString Tree_str = tc.GetItemText(hItem);
CMainFrame *pMainFrame=(CMainFrame*)AfxGetMainWnd();
if (Tree_str==_T("Str"))

Handle WM_KEYDOWN message and inside the message check the key pressed is enter.
void CMyTree::OnKeyDown( UINT nChar, UINT nRepCnt, UINT nFlags )
{
if( nChar == VK_RETURN )
{
}

You can use of CTreeCtrl::GetItemText for get string of an item.
|
|
|
|
|
this is right syntax;
CString GetItemText( HTREEITEM hItem ) ;
how can i enter HTREEITEM hItem ,on enter the key,

Did you see MSDN see an example of MSDN:
HTREEITEM hCurSel = m_TreeCtrl.GetNextItem(TVI_ROOT, TVGN_CARET);
// report it to the user
if (hCurSel == NULL)
{
AfxMessageBox(_T("There is no selected item"));
}
else
{
CString str;
str.Format(_T("The currently selected item is \"%s\""),
(LPCTSTR)m_TreeCtrl.GetItemText(hCurSel));
AfxMessageBox((LPCTSTR)str);
}
