Thanks for the link.
I looked at the code. I saw no "subclassing" going on besides what MFC already does for you.
It is an owner drawn control implemented by overriding WM_PAINT and drawing the entire control
instead of using the Windows ownerdraw interface.
My point in previous posts is that no matter what wrapper you are using, if the control is a
Windows control then aside from making an owner-drawn control, there's no way to magically
change the way the control draws itself. Unfortunately, Microsoft chose to not fully implement
transparency (via WS_EX_TRANSPARENT) in all controls and multi part controls like the group box
that require more than one background brush do not work well with the WM_CTLCOLOR messages.
I have no idea how ATL wraps a window, but if there's no way to intercept every message to the
window then it sounds like a pretty lame wrapper. Even the lowly MFC lets you do that

Yup...thanks for your post. Looks like I am heading for another sleepless night.

Hi, I made a BHO for a Single Sign On system and worked fine in IE6, but doesn't in IE7.
I belive IE7 is blocking the messages sent to and from my controlling app, because PostMessage and SendMessage return OK but my app dont receive any message.
Also my BHO Dll haves a shared data area, and the data isn't beign refreshed.
Does anyone knows if IE7 block messages sent outside IE?

You should monitor the IE7 window with spy++ and watch out for the message you are sending it.

Thanks mate, I can see a lot of WM_USER messages going out, but not mine's 
I dont know whats happens, in IE6 the messages were sent ok
I'm afraid MS people limited BHO communication due malware stealing logins before SSL encryption

Are you using XP or Vista? If it's Vista, then the behavior you're seeing is caused by extra security features that are turned on in protected mode.

I'm testing the BHO in XP SP2 so no protected mode is involved :S
My boss isn't going to be happy if I tell him that we must abandon the project or do it for Firefox

Hi.
I am a newbie in programming.
Here is a problem which I want to know.
I have one small exe file.
And I want to use one function of that exe file in my program.
Is it possible to call the function in my program?
If so, please give me the way how to do that.
Thanks for your help, sincerely.

It's not possible to directly call a function in another EXE from your EXE.
How is it you even know the small EXE has a function you need?

The answer is, it depends. If the function is exported from the executable, you may be able to call LoadLibrary() for the executable and then GetProcAddress(). Additionally, you may have to know what the calling convention is for the function, in order to invoke it correctly.

Really? I thought you could only get at the resources that way.
Hopefully the function doesn't use anything that requires initialization, like MFC

|

You can, but I never tried myself. Take a look here[^]
|
|
|
|
|
I stand corrected
I still would worry (at least) about run-time initialization if the function uses the CRT, MFC,
etc. I exercise my right to choose not to do it
Cheers!

I agree, it's not something that should normally be done. After all, what the hell are DLL's there for?
Another way I know of is to build a type library for the exe and add the export into it, again though, what's the point?

Sure?
How can you do that?

How to use large cursor as in PhotoShop?
As I know, cursor size is maximum to 32x32 pixels.
Pens in PhotoShop use very large cursors, how to do that?
|
|
|
|
|
Don't use a cursor, instead use a bitmap and draw it to the cursors location.
|
|
|
|
|
|
Take a look at this[^]. I used depends.exe and it seems that all they do is draw transparent bitmaps.

I have this line of code :
TargetList.push_back(CSTREAMS(*(SrcList[i])));
where CSTREAMS is a userdefined class and TargetList is a vector. So i'm just calling the constructor without the new keyword. I think this creates a temporary object, wich is copied by the vector and then destroeyd, so no memoryleak. Is this correct ?

Hi all,
I've written an MFC MDI application where I need an additional child frame to show other aspects of my data. So I derived a class from CMDIChildWnd and created the Icon, Accelerator and Menu. My view for this child frame is derived from CFormView and has a chart control an a button control.
I call/create the child frame by choosing a menu entry as follows:
<br />
void CmyApp::OnAnsichtnewView()<br />
{<br />
CMainFrame *pFrame = STATIC_DOWNCAST(CMainFrame, m_pMainWnd);<br />
pFrame->CreateNewChild(RUNTIME_CLASS(CmyChildFrm), IDR_myTYPE);<br />
<br />
CRect cr;<br />
pFrame->GetActiveFrame()->GetClientRect(cr);<br />
<br />
CDocument *pDoc = pFrame->GetActiveDocument();<br />
CRuntimeClass *pRTC = RUNTIME_CLASS(CmyFromView);<br />
CCreateContext context;<br />
context.m_pCurrentDoc = pDoc;<br />
context.m_pNewViewClass = pRTC;<br />
context.m_pLastView = NULL;<br />
<br />
pFrame->GetActiveFrame()->CreateView(&context);<br />
}<br />
In my view class I've overwritten the OnSize method as follows:
<br />
void CmyFormView::OnSize(UINT nType, int cx, int cy)<br />
{<br />
CFormView::OnSize(nType, cx, cy);<br />
<br />
if(m_Chart.GetSafeHwnd() != NULL)<br />
{<br />
m_Chart.MoveWindow(0, 0, cx-30, cy);<br />
AfxMessageBox("Chart resized");<br />
}<br />
if(m_Button.GetSafeHwnd())<br />
{<br />
m_Button.MoveWindow(cx-30, 0, 30, 30);<br />
AfxMessageBox("Button resized");<br />
}<br />
AfxMessageBox("Form resized");<br />
}<br />
When I run my programm and do a resize on my new child, I only get a "Form resized" MessageBox. So, obviously m_Chart and m_Button don't get a Hwnd but I don't know why.
Can anybody give me a hint on this?
Thanks,
Frank.
