Well it's not exactly an HTML rendering engine, but the following control has support for a bunch of tags. I haven't looked at the source that I can remember, but you may be able to rip out it's core and use it for your own purposes.

Hey,
here's a good newbie question for everyone:
I'm currently using a 2d graph DLL that i got from codeproject:
CXGraph
And am running it on a split pane with a control panel the right. when the user clicks on the graph, i want to pull the value for that point on the graph out of the graph dll and access it in my project, but the click message seems to get caught in the graph function.
is there any way i can catch the mouseclick action in the main app?
Many Thanks,
Mike

You could intercept it in your derived class then post it back to the MainWnd
AfxGetMainWnd()->PostMessage(...
My neighbours think I am crazy - but they don't know that I have a trampoline. All they see my head bobbing up and down over the fence every five seconds

Hello, there,
I am currently working on a project. There is a combo box. I'd like to know how I can disable the dropdown arrow of it or hide the dropdown arrow. In my project there is two setting, one is keeping the input history, one is not keeping the input history.
I tried m_Combo.ShowDropDown(false)when not keeping the history, but there is a black line under it and it doesn't look good. Is there a way to solve this problem?
Thanks a lot in advance.

One way is to subclass the control, and handle WM_LBUTTONDOWN yourself, to effectively disable it that way, or alternatively, at run-time create an edit control in it's place which is ES_READONLY.

If your wanting to disable it do this
have a combo box and give it a control name like m_example
then on your button or whatever your using
lets say your using a button and the button is called History
you put under OnHistory()
m_example.EnableWindow(FALSE); // disabled combobox or whatever linked to
m_example.EnableWindow(TRUE); // enables combobox or whatever linked to
now if you wanna hide it all together
i would do this under the OnHistory()
m_example.ShowWindow(SW_HIDE); // hides the combobox or whatever linked to
if you want the window back then
m_example.ShowWindow(SW_SHOW);// shows the combobox or whatever linked to
GOOD LUCK,
HOPE THIS HELPS.

thanks a lot. But I just want to disable the drop down button and make it work as an edit box. I don't want to disable the whole thing.
Thanks.

what you can do is:
Just iterate the windows of the combo box. Combo box contains the edit box and the button.
For example
char szClassName[256];
CWnd* pWnd=(CWnd *)m_combo.GetWindow(GW_CHILD);
::GetClassName(pWnd->GetSafeHwnd(), szClassName, 256);
while( strcmp( szClassName,_T("Button")) != 0 )
{
pWnd=(CWnd *)m_combo.GetWindow(GW_HWNDNEXT);
}
//Got the button
if( pWnd )
pWnd->ShowWindow( SW_HIDE );

I have seen issues with something that works fine in all Windows OS's except some machines running 2000 or XP. I'm using a WM_COPYDATA to send text between windows. When it fails, messages that should appear do not. It is extremely hard to narrow it down further than that.
Is anyone aware of any issues using this message on the newer OS's?

Does it fail consistently? Have you used Spy++ on the recipient window to see if it is receiving the message?
Perhaps the author of this article might have some knowledge of it failing.

Well, I've looked into it a bit further. It is actually recieving the message but the pointer to the data seems to be off be quite a bit (haven't counted the offset yet). I can see the start of my struct in the dump but it is preceeded by a bunch of "junk". I really don't know why. I have one long and 2 int's followed by a char[256]. The long, int's and string are all in there but not at the correct starting point.
Any ideas?

Having not ever used that message before, I'm afraid not.

I noticed someone else mentioned a similar issue in the article you linked to. No answer posted unfortunately.

It appears that the author has not been good about answering any of them. Bummer.

Hi,
I saw a thread where wm_copydata failed due to the nvidia tray-icon app.

Ok, but since Dave_ was the one asking the question, you might want to respond to him.

Help, please!
How to access a member in a base class from within an __asm block?
Suppose, we have:
struct s1
{
int a;
};
struct s2 : s1
{
int b;
};
struct s3
{
s2 c;
};
then:
__asm mov eax, [eax]s3.c.b // just fine
but
__asm mov eax, [eax]s3.c.a // ERROR
|
|
|
|
|
Use this instead:
__asm mov eax, [eax]s3.c.b.a

Yes, this works! Why, however this doesn't:
struct s2 : POINT
{
int b;
};
struct s3
{
int c;
};
__asm mov eax, [eax]s3.c.b.x // 'x' : ambiguous member name in 'second operand'
'x' couldn't be a reserved name, could it??
Is there any way to clarify it to compiler except for defining an offset explicitly, like:
enum { s3s2x = offsetof(s3, s2.x) };
and then
__asm mov eax, [eax + s3s2x]
|
|
|
|
|
How are you expecting to get to 'b' or 'x' through struct s3 since struct s3 and struct s2 know nothing of each other?
__asm mov eax, [eax]s3.c.b.x
^ this dot makes no sense

Sorry, of course:
struct s2 : POINT
{
int b;
};
struct s3
{
s2 c;
};
__asm mov [eax]s3.c.b.x // error
__asm mov [eax]s3.c.x // error also
And, unfortunately, if s2 has no data members,
that is
struct s2 : POINT
{
void foo();
};
then I wouldn't know how to access POINT::x at all as
__asm mov [eax]s3.c.x
results in error again...

See if this helps:
int xx = ss3.c.x;
__asm mov eax, [eax][xx]
