the tool tip does not pop up any more. Why, it should be '0'.
Without a control with ID==0 you will no longer get the message.
Anyway, do you need to create a CToolTipCtrl? That may be why it's showing two tooltips.
Try just calling EnableToolTips(TRUE); and handling ON_NOTIFY_EX(TTN_NEEDTEXT, IDC_EDIT_ExampleText, SetTipText)
like you were.

As part of enabling tool tips, you handle the TTN_NEEDTEXT message by adding the following entry to your owner window’s message map:
ON_NOTIFY_EX( TTN_NEEDTEXT, 0, memberFxn )
memberFxn
The member function to be called when text is needed for this button.
Note that the ID of a tool tip is always 0.
The information was from MSDN.

Good people,
I am trying to place a Banner across the top portion of my dialogue. I am using a bitmap I created. I create the bitmap with the dimensions of the picture control that I place on the dialogue. My goal is that it will run across the top part - giving the application a nice look and feel. However, I have been unable to get it to size correctly. Even though I use the exact dimensions (in pixels) of the picture control, when I compile and run it, the size is always smaller (and sometimes larger) than the area it needs to cover on the dialogue.
How can I get it to display correctly (and possibly even shrink or grow as the dialogue is adjusted)? Any help or thoughts would be greatly appreciated. BTW, I am using VS 2003 .NET. I am building MFC Dialogues.

How are you getting the size of the picture control?
To resize a bitmap just blit it to the picture controls DC using StretchBlit().
|
|
|
|
|
How do you use that function?
|
|
|
|
|
Can you show code snippet how do you use
|
|
|
|

Thanks for replying.
I am not using any code except the one automatically generated when you place a picture control on a dialogue and assign a bitmap.
To see the effect I'm trying to get...look at this screenshot http://sourceforge.net/project/screenshots.php?group_id=95013&ssid=18186 of a KeePass dialogue, notice how that banner is across the top of his dialogues. Any idea about how to do that?
Thanks,
BP

yes I see,you can use of StretchBlitfor show your image but for get dimensions of window you can use of GetWindowRect<screentoclient< code=""> now you have left/right/top/bottom of window and you can use of their on StretchBlit

Friends,
I have an edit control on a dialog box. I've placed some text in the edit box during dialog initialization. The problem is that, when the dialog appears on the screen, the entire text in the edit box is *selected*. I want to remove this selection, however i want the focus to remain in the edit control. I am doing something as follows but it is not working:
BOOL CWebServiceURLDlg::OnInitDialog()
{
CDialog::OnInitDialog();
m_editUrl.SetWindowText(_T("Tomato"));
m_editUrl.SetSel(-1, 0);
return TRUE;
}
Please tell me how to remove the selection.

Try this
m_editUrl.SetSel( -1, 0, 0 );

Not working at all

That's because your selection is being cancelled by what OnInitDialog() is doing when it finishes. You need to call PostMessage() instead, and in the handler for the message, call SetSel(). That will work.

You should return FALSE , if you want to set focus to a control in a dialog, from OnInitDialog.
As far as the selection issue is concerned I don't see any problem here. It's working here.

Hi,everyone. My application is based on Muti-Doc (VC6.0).
I created a controlbar in mainfrm (OnCreate()) and then created a tabcontrol in the controlbar (also in OnCreate()), then I created a TreeCtrl in the TabCtrl.
HTREEITEM hti1 = m_wndTree1.InsertItem(_T("Chapter1"));
HTREEITEM subroot1=m_wndTree1.InsertItem("section1",hti);
HTREEITEM hti2 = m_wndTree1.InsertItem(_T("Chapter2"));
Now I want to add "Chapter3" in the TreeCtrl by menu, what should I do???
If you can show some codes , that's better. Because I'm a begginner.
Thanks a lot.

Um...
HTREEITEM hti3 = m_wndTree1.InsertItem(_T("Chapter3"));
seems obvious to me....
If you want a menu to add the item, then you need to put that code into the method called by a menu item.

I created the treectrl in mainfrm.cpp, and used ID_FILE_NEW_ADD menu item to do this work.
I add this to my codes:
void CMainFrame::OnFileNewAdd()
{
// TODO: Add your command handler code here
HTREEITEM hti3 = m_wndTree1.InsertItem(_T("Chapter3"));
}
But it didn't work.

Which didn't work InsertItem or event of ID_FILE_NEW_ADD

Ok, there is something I really don't get. I'm triing to use the function _strnset_s, but I get the compiler error : '_strnset_s': identifier not found, even with argument-dependent lookup.
The thing is that string.h is included in my project and at the line just before this one, I used strrchr wich need the same include and the compiler doesn't complain about this one. What did I do wrong?
here a very short version of my code:
stdafx.h :
#pragma once
#define WIN32_LEAN_AND_MEAN
headers
#include <stdlib.h>
#include <malloc.h>
#include <memory.h>
#include <tchar.h>
// Others
#include <stdio.h>
#include <string.h>
#include <afx.h>
Form1.cpp :
#include "stdafx.h"
#include "Form1.h"
Form1.h :
#pragma once
#pragma push_macro("GetObject")
#undef GetObject
#pragma push_macro("MessageBox")
#undef MessageBox
namespace VampireReader
{
using namespace System;
using namespace System::ComponentModel;
using namespace System::Collections;
using namespace System::Windows::Forms;
using namespace System::Data;
using namespace System::Drawing;
using namespace System::IO;
using namespace System::Runtime::InteropServices;
using namespace System::Text;
private:
System::ComponentModel::Container * components;
void InitializeComponent(void)...
private: void fOpenFile()
{
csDest = strrchr( csFName, '\\' );
_strnset_s( csDest, sizeof(csDest), ' ', 1 );
}

Maybe you are pointing to a string.h from a previous sdk.
Right click on the include, open string.h, and search for "_strnset_s".
If it's not there you need an SDK update.
|
|
|
|

_strnset_s is found in C++/CLI of VS2005. Looks like you are using Managed C++ of VS2003 because "System::ComponentModel::Container* components;" is MC++ 2003 and "System::ComponentModel::Container ^components;" is C++/CLI 2005.

Will really appreciate the help
Thanks

Look through your project ( a find in files can do this for you ) and see why it's looking for this file.

Thanks for the reply but it didn't work for this problem. When I do "FIND IN FILES" it gives, there is nothing like sensors.obj.
I am just hung up with the problem. What else I can do?
Thanks again
