Hi
I am beginner in VC++. I have got a CTreeCtrl in my application from which I want to delete HTREEITEMs upon press of delete key. First I proceed to delete the related data structure for the HTREEITEM selected. Then I proceed to delete the HTREEITEM using the DeleteItem(HTREEITEM) method. If the HTREEITEM to be deleted is a folder with numerous sub items with in it, do i need to delete all sub items individually before deleting the parent HTREEITEM ?
OR could i directly delete the parent HTREEITEM ?
Please help me out on this.
Thank You,
Jayanand.

Hi 
You can handle the TCN_DELETEITEM message that the tree control will send whenever an item is deleted ... this will happen for each child item after you delete a parent item manually.
sorry this answer is a bit brief.

What is the easiest way to append a DWORD (the result from GetTickCount in this case) to a BSTR, the following works but I know there must be an easier way:
CComBSTR szString = "";
char szStartTime[11] = "";
sprintf( szStartTime, "%ul", GetTickCount() );
szString.AppendBSTR( szSessionID );
szString.AppendBSTR( szSep );
szString.AppendBSTR( szIPAddress );
szString.AppendBSTR( szSep );
szString.Append( szStartTime );
And the following doesn't work (much to my dismay):
CComBSTR szString = "";
DWORD dwStartTime = GetTickCount();
szString.AppendBSTR( szSessionID );
szString.AppendBSTR( szSep );
szString.AppendBSTR( szIPAddress );
szString.AppendBSTR( szSep );
szString.Append( dwStartTime );
I also tried casting the DWORD as different types but none of this worked. Any suggestions. Thanks.

Hi !
May be it's the one you'was looking for?
#include <sstream>
using namespace std;
sstringstream ss;
ss << LPCSTR(szSessionID) << LPCSTR(szSep) << LPCSTR(szIPAddress)\
LPCSTR(szSep) << ULONG(::GetTickCount());
CComBSTR szString(ss.str().c_str());
Best regards,

hi,
i want to use an edit control in a idockingwindow in the right pane of the explorer.
the problem: if i press backspace to del the last letter in the edit control, the explorer goes one level up in the directory.
so, how is it possible, to use the backspace (and all the other special keys) for the edit?
thanks
|
|

|

You need to implement IInputObject and the appropriate methods to get the backspace to work correctly when your docking window has focus. I am in the process of a couple articles that explain this and other things within Explorer bands and toolbars.
If time permits hopefully this week 1 or 2 of the articles will come out.
Cheers,
-Erik

Hello,
I now C++ pretty well but I'm a MFC beginner. I'm trying to learn it by myself.
How can I change the caption of a button? How can I disable it? I looked into the CButton Class and I can't find how to change it 
Anyone can answer this newbie question? (I wish this was as easy as VB) hehe
Thanks
|

CButton is derived from CWnd, so you can call methods like
SetWindowText to change the caption or EnableWindow() to enable/disable the window.
Look at all the methods of CWnd which will show you what you can do.

Try this:
GetDlgItem(IDC_YOUR_BUTTON_ID)->EnableWindow(FALSE);
GetDlgItem(IDC_YOUR_BUTTON_ID)->SetWindowText("new text");

What i do is that in the dialog editor you put the & sign before the letter with the caption.
I hope this is what you need .

handle the OnUpdate() message and set the scroll sizes there depending on the 'size' of your doc and the font size you are using

Handle the WM_GETMINMAXINFO message, where you tell Windows the min/max sizes of your windows.

I need to catch the WM_KEYDOWN messages that are send when the user write a string in a window of another process.
Actually it is to convert the string to an asian character set.
Is it possible ?
If not, is there a way to avoid the problem ?
Thank you
Eric
