same project to build dll and static lib

I have a project which I want to build as a dll in one project workspace and as a static lib for another project workspace. can you somebody suggest ways to do this if it is possible? If I need to have two different project files, how do I create the second one in the same directory as the first one. and if it is possible to do with just a single .dsp file, what should I do in this .dsp file? Thanks in advance.

I would recommend having separate .dsp files. You can put them both in the same workspace (.dsw).

Hello everyone, I have created an activex control using VC.net, the control works fine if i use the activex test container, or a small vc program i wrote to test the control. But if i use it in vb it doesnt, the problem is when i try to call the SetTimer funtion. from what i can see, the hwnd value is Null when called from vb, i think it is something to do with vb been the container ?? but i am not sure... does anyone have any ideas, as the rest of the control works a treat, its just this one point...

Thanks in advance

I'm not sure I understand your question...
So, you say you have Word (or another application) open and your application that is also open. The user write something in Word and then delete it. You want to retrieve in your application what the user has deleted ? Is that correct ?
It looks really strange to me... But ok there could be option like using hooks on Word inside your application (that will allow you to retrive all keys that are pressed in Word). But I don't have a lot of knowledge in that field. Take a look on this site, I think there are a lot of articles that cover this subject.

If it is not what you were asking for, then try to reformulate your question a little bit clearer

You can write a keyboard hook to do that. Look for SetWindowsHookEx Win32 API function.

Owner / Custom Drawing a Header Control

I am trying to handle drawing a header control so that I can support
multi-line items. It tried both owner and custom draw but neither will tell
me the control is 'hot' when the mouse is over it. Everything is ok if I
revert back to standard drawing so the window styles must be right. Can
anyone suggest what is wrong?

This may be a simple thing but I,m stuck. In the last function of this class I am trying to show m_image_new. This is not for a serious project I am just learning, but the project will not compile. The class is:-

// dlg_new.cpp : implementation file
//

#include "stdafx.h"
#include "EditTest.h"
#include "dlg_new.h"

#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif

/////////////////////////////////////////////////////////////////////////////
// dlg_new dialog

dlg_new::dlg_new(CWnd* pParent /*=NULL*/)
: CDialog(dlg_new::IDD, pParent)
{
//{{AFX_DATA_INIT(dlg_new)
m_image_new = _T("");
//}}AFX_DATA_INIT
}

void dlg_new::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
//{{AFX_DATA_MAP(dlg_new)
DDX_Control(pDX, IDC_BUTTON_IMAGE, m_image_button);

//}}AFX_DATA_MAP
}

BEGIN_MESSAGE_MAP(dlg_new, CDialog)

}

void dlg_new::OnButtonImage()
{
//using ::CWnd;
m_image_new.CWnd::ShowWindow( SW_SHOW );
// TODO: Add your control notification handler code here

}
The error I get is that CWnd is not a member of CString.

Please help

Try
GetDlgItem(IDC_STATIC_IMAGE)->ShowWindow(SW_SHOW);
instead of
m_image_new.CWnd::ShowWindow( SW_SHOW );

i think m_image_new is a CString variable and i completely don't understand
what you're trying to do with this :

m_image_new.CWnd::ShowWindow( SW_SHOW );

If you use MFC, you can use the CTime and CTimeSpan classes, they will allow you to do exactly what you are looking for.

Something like:

CTime Time(2005,6,2,0,0,0);  // Look in the doc for the "daylight savings time" that you want to use
CTimeSpan Span(100,0,0,0);

CTime NewTime = Time + Span;  // NewTime will hold the time you are looking for

[EDIT] I don't use that very often so you have to check if that works, it was just for information... [/EDIT]

Problem with ListCtrl while using Manifest file for XP Look

Neeranjan2-Jun-05 1:29

Hi,

I have an application (in VC++ 6.0) wherein it displays the images in ListView. So the application starts displaying the images from the Top left corner (0,0).
Now I have added the manifest file (to give XP look to application) in applicatoin resource successfully. (as outlined in the below mentioned link http://www.codeguru.com/Cpp/controls/controls/article.php/c5227/)
The application is having the XP look but the images are displayed from the Bottom left corner.

Please I need some help in understanding
1. Why origin of the ListCtrl is changing
2 .How to set the origin of the ListCtrl to top left corner (0,0) so that the images are displayed from the top left corner (0,0) ?

Any help in this regard is highly appreciated.

Thanks in advance

Thanks & Regards,
Neeraj

Grayscale Image Display

Reiste2-Jun-05 0:51

Hi.

This problem has been driving me mad for too long now. I have a 640x480 char array of data. I need to display that in grayscale in a Window (currently using a CFrameWnd). I can't copy it to a 640x480x3 array and use SetDIBitsToDevice - that isn't fast enough (it's for a video application).

At the moment, I am using SetDIBitsToDevice with BITMAPINFO.biBitCount set to 8. The image displays correctly, except not in Grayscale - it's in a psychedelic 256-color palette mapping of some sort - I assume Window's default.

Try as I might, I can't get it to use a grayscale palette. I can't even create a palette from scratch - maybe if I could, I could get this to work. I've read Chris Becke's article on Bitmaps, and checked out forums all over - but nothing seems quite related to what I want to do. I can't believe that it is this difficult!

If anyone has an answer, or can recommend an article that would help... please do!

Hi All!

What's the SDK function of the DeflateRect of MFC

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
