ohh, yes, the CALLBACK is there,
i even tried replacing CALLBACK with __stdcall
i have never had any problems using EnumWindows outside of MFC projects,
if it comes down to it i may just use GetTopWindow()
and GetNextWindow();
although i really prefer not too

Do you use the CALLBACK function as a member-function of your dialog class?
In case you do, take a look at this article

This worked fine for me:
BOOL CALLBACK GetWindows( HWND, LPARAM )
{
return 0;
}
BOOL CMyDlg::OnInitDialog()
{
CDialog::OnInitDialog();
EnumWindows(GetWindows, 0);
}

Hi,
I've been trying desperately integrating the new compiler into the VC++ 6.0 IDE. I put the directories (bin, include and lib) of the toolkit at top of the list and the new compiler compiles 
But now I get either linker errors (LNK2001, over 300 times...) for all the STL-Stuff or - if i change the order of the directories - get over 1000 compiler errors in the header files of the toolkit.
has anybody successfully integrated the toolkit to vc6 or knows good links about this topic (i searched the web but didn't manage to find something useful)

For your situation, I hope that I am wrong, but I don't think that you can put the MS VC Toolkit 2003 into VC6.0, partly if not entirely because of the vast version differences.

Hello!
I've been told that everything to be drawn in a dialog needs to be in the OnPaint method. Or else when you minimize and maximize again you won't seen anything.
i have these two functions that paint on the dialog when i click the left mouse button :
<br />
void CVentanaPizarra::OnMouseMove(UINT nFlags, CPoint point) <br />
{<br />
if (nFlags == MK_LBUTTON)<br />
{<br />
CClientDC dc(this);<br />
CPen Lapiz; <br />
<br />
Lapiz.CreatePen (PS_SOLID,1,RGB(0,0,0)); <br />
dc.SelectObject(Lapiz); <br />
<br />
if ((m_PosMouse.x!=-1)&&(m_PosMouse.y!=-1))<br />
{<br />
dc.MoveTo(point.x, point.y);<br />
dc.LineTo(m_PosMouse.x,m_PosMouse.y);<br />
}<br />
dc.MoveTo(point.x, point.y);<br />
dc.LineTo(point.x+(int).5, point.y+(int).5);<br />
m_PosMouse=dc.GetCurrentPosition(); <br />
}<br />
CDialog::OnMouseMove(nFlags, point);<br />
}<br />
<br />
void CVentanaPizarra::OnLButtonUp(UINT nFlags, CPoint point) <br />
{<br />
m_PosMouse.x=-1;<br />
m_PosMouse.y=-1;<br />
CDialog::OnLButtonUp(nFlags, point);<br />
}<br />
the problem is that it's not in the OnPaint function.
How could i do to stop what i've drawn from erasing when i minimize the window?
thanks!

The OnDraw function is the funtion that repaints the view whenever it needs to be painted. Place your drawing code within that function (or call the function that you have doing the drawing in OnDraw) and that should solve your problem. You can also call your view class's Invalidate() function to repaint the view as you need to.
Good luck on your programming efforts.

i'm trying to store points, and then redraw in the OnDraw function, but i'm not successful.
I've declared in the header file
typedef std::list<CPoint> CListaPuntos; inside the class there's:
CListaPuntos ListaPuntos;
In the constructor of the class, i've written:
m_PosMouse.x=-1;
m_PosMouse.y=-1;
this->ListaPuntos.push_back(m_PosMouse);
In the list, i store a Cpoint variable with (-1,-1)
Then, this is the function which draws and stores points in the list
void CVentanaPizarra::OnMouseMove(UINT nFlags, CPoint point)
{
if (m_DibLapiz)
{
CRect rect;
GetClientRect(rect);
if ((nFlags == MK_LBUTTON) && ((m_PosMouse.x>rect.left+90) || (m_PosMouse.x==-1)))
{
CClientDC dc(this);
CPen Lapiz;
Lapiz.CreatePen (PS_SOLID,1,RGB(0,0,0));
dc.SelectObject(Lapiz);
if (point.x>rect.left+90)
{
CPoint punto;
if ((m_PosMouse.x!=-1)&&(m_PosMouse.y!=-1))
{
this->ListaPuntos.push_back(point);
dc.MoveTo(point.x, point.y);
dc.LineTo(m_PosMouse.x,m_PosMouse.y);
}
dc.MoveTo(point.x, point.y);
this->ListaPuntos.push_back(point);
punto.x=point.x+(int).5;
punto.y=point.y+(int).5;
dc.LineTo(punto.x, punto.y);
this->ListaPuntos.push_back(punto);
}
m_PosMouse=dc.GetCurrentPosition();
}
}
CDialog::OnMouseMove(nFlags, point);
}
this function compliments the abovementioned one:
void CVentanaPizarra::OnLButtonUp(UINT nFlags, CPoint point)
{
m_PosMouse.x=-1;
m_PosMouse.y=-1;
this->ListaPuntos.push_back(m_PosMouse);
CDialog::OnLButtonUp(nFlags, point);
}
and this is the onpaint function:
void CVentanaPizarra::OnPaint()
{
CPaintDC dlgDC(this);
PintarBlanco(dlgDC);
if (ListaPuntos.size()>1)
{
CPoint punto1, punto2;
for (CListaPuntos::iterator i = ListaPuntos.begin(); i != ListaPuntos.end(); i++)
{
punto1= *i;
if (i==ListaPuntos.end())
break;
if (punto1.x!=-1)
{
dlgDC.LineTo(punto1.x,punto1.x);
dlgDC.MoveTo(punto1.x,punto1.y);
}
i++;
if (i==ListaPuntos.end())
break;
punto2= *i;
if (punto1.x!=-1)
dlgDC.LineTo(punto2.x,punto2.x);
dlgDC.MoveTo(punto2.x,punto2.y);
}
}
}
something is drawn, but not what i want, or what i've drawn with the mouse.
any ideas?
thanks!

First of all, you are still drawing in the mousemove handler, which will not exactly make it easy for you to know what drawing works and what don't. Moreover, this code is leaking GDI-handles, as you don't unselect the pen you have created and selected. The paint handler, on the other hand, will use whatever pen happens to be selected into the CDC.
You are adding point twice to the list, which looks slightly odd. You seem to be moving to the current position, drawing backwards, and then forward again, is this really what you intended.
The OnPaint-handler is definitely odd as well - you are drawing and then moving?
I think you should get some pen and paper, and outline what you really want to do. Basically, when all prerequisits for drawing is fullfilled in OnMouseMove, just add the current point to the list. Invalidate and redraw the window as appropriate. Then, in OnPaint, create and select the pen you want to draw with. Set the initial position with MoveTo. Loop the list, and call LineTo for each point. Voilà!

Hi,
We are planning to send some Fax related data as a SOAP with Attachments messages to a Fax consuming Service over MQ. I would like to know if it is possible (in .NET, PocketSOAP or SOAPToolkit) to create the SOAP Message along with attachments and then serialize it to a byte stream, which can then be used to populate the MQ Message. What I am looking for is the equivivalent of the SAAJ library in Java. Can anybody point me to some info on this or give advise.
Thanks,
Kris

One note, AFAIK .NET uses DIME, and cannot read MIME, so you won't get 100% compatibility. I think in the future there is supposed to be a "standard" format that everyone will use. Now, if you are 100% Microsoft on all sides, this won't be a problem. And some non-Microsoft code (e.g., Apache Axis) can understand both.
Somebody correct me if I'm wrong, though.

Thanks for your reply. Unfortunately I dont have a choice about the receiving end. It expects SOAP with MIME Attachments. I couldnt find any examples with MIME attachments and .NET. That's why I had mentioned - PocketSOAP which seems to support it but was wondering if it was tranport dependent (as I am not using HTTP but MQ). Apache also has a C++ Axis implementation. I should probably look at it too. Any other suggestions would be welcome.

That is what we found as well. Also we got DIME working between ASP.NET (IIS) and Tomcat. It wasn't easy but it works.

How can i load the icon from antother application/process and set it as the icon for a MFC list control item
|
|

hi!
I never did THIS but... here is a code sample
how to load some ressource from a DLL
extern "C" DllExport BYTE* GetLogo(int &nSize) {
DWORD dw;
HRSRC hRes = FindResource(g_hInstance,_T("IDR_LOGO"),_T("Images"));
dw = GetLastError();
HGLOBAL hg=LoadResource(g_hInstance,hRes);
LPVOID lpRes=LockResource(hg);
nSize = SizeofResource(g_hInstance,hRes);
dw = GetLastError();
return (BYTE*)lpRes;
}
I think you have just to get the HINSTACE to the app you want, and then load the ICON from it!
good luck!

The DirectX SDK (DirectShow) is one of the best starting points for writing codecs. You can download it from microsoft.

I have a project that will use a tabbed control (property pages?) as the primary interface. The tabs are arranged in such a way as to guide the user in the proper order of steps. Anyway, given that I need a title bar, a menu bar and possibly a toolbar - and eventually the whole thing needs to be sizeable, which is the best interface to use: MDI, SDI, or Dialog based? 
I've done a lot of C++ coding, but have very little experience in "starting from scratch" - so I plan to use the wizard in Microsoft's Visual C++ to get me started.
Any suggestions, pointers to articles, etc. would be greatly appreciated.
Thanks!!

Do you need multiple document support? If not, then you can rule that app structure out. From what you have been saying, a SDI style app with a CFormView view class. That would probably be your easiest straightforward path to take.
Keep in mind that you could use a CDialog-based application structure. Toolbar(s) can be added to a dialog and of course a menubar. There are articles on this site of how to add a toolbar to a dialog. Skim the articles on this page for help on adding resizability and toolbars to a dialog: http://www.codeproject.com/dialog/[^]
I hope this helps. Good luck in your programming efforts!

Thanks, bneacetp. I've been doing some more study since my post, and at this point I think I'm leaning toward the learning curve of the SDI style - since I'll eventually need most of what it does (including printing from the app, resizing, etc)
Thanks, also, for the well wishes!
Happy Programming and God Bless to you, as well!

I have a MFC Dialog which contains a Bitmap. When the application is run the dialog is always on top and I cant have any other Windows placed over it.
I have looked at the Dialog settings and cant find any that would cause this effect (problem).
Have I overlooked anything as I want to place the dialog in the background when required.

I have a "Generic CWnd" class named CData. This class will hold all of my data for the program. The "instance" is created in the CMainFrame constructor. Serveral dialog classes are created and launched fron the CData class. However, I cannot get the data from those dialogs realized or recognized by CMainFrame::m_CData(my instance of CData class in CMainFrame). The dialogs are created "modeless" in CData; and while active CData gains the data; but when returned to CMainFrame the data is not there in CData.
Any ideas?

Sorry if sounds patronising
have made the CDialog objects or the getter methods public in the CData class?
If you clarify what your are trying do.
