Hi,
I have created a multi line edit control and assigned a member variable say m_strOutput...
when i do m_strOutput += _T("\n") expecting the next time string to be printed in next line , the string is not printed in next line but appended to previous string.... How to go to next line in edit control????

Have you tried \r\n instead?

yes i tried that also but no result

Does the control have the ES_MULTILINE style?

you should try to do this: m_strOutput+=_T("\r\n")

Maybe this is not the best forum to answer my question, but because plugins can be written in C++ I hope somebody who is making them will answer
Can somebody tell me if browser plugins for IE (activeX) or firefox can read (any) files on the HDD? (when they know exact path).
Somebody have told me that it is insecure to store sensitive data into "application data" folder because it can be accesses by web plugins.
Is it true? I'd guess they can access any files/folders with active user permissions.
Thank you

Since the code is C++, why wouldn't they be able to? See here for BHO examples.

That's what I've thought ... but I have no idea about firefox

Browser plugins can access files in the computer. Just take the case of online virus scanners, they are able to scan the entire HDD for viruses.

Hi,
I'm creating a whole bunch of buttons during run-time. When anyone of these buttons is clicked it should go through the same function, but with different parameters. A small example to clarify;
for (x = 0; x < 10; x++)
{
TButton *b = new TButton(this);
b->Caption = "My button " + IntToStr(x);
b->Top = 100;
b->Left = 100 + 10 * x;
b->OnClick = myfunction(x);
b->Parent = this;
}
void __fastcall TForm1::myfunction(int x)
{
ShowMessage("Button " + IntToStr(x) + " clicked");
}
This, however, doesn't work. I get an "Not an allowed type" error when compiling. Apparantly I can't pass variables like this to myfunction.
I can only do something like this;
b->OnClick = myfunction;
void __fastcall TForm1::myfunction(TObject *Sender)
{
ShowMessage("Button ? clicked");
}
But how do I know which of the ten buttons is clicked now? How can I pass this information to the function?
thanx
Willem

See, for instance [^], I know it's Delphi, anyway it is conceptually the same issue.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

verry nice, didn't think of that one
but the problem with this is, that it will only work with a known button, one that's written in the code.
when creating new buttons it wil return just the "button" methode as the sender.
so you know that a button is pushed and not an (ai) editbox or that it was a counter. but wich button you still don know.

Looks like David Crow has given already the solution [^].

I suspect there's a joke in there somewhere, but, alas, it escapes me.

In myfunction(), what does Sender represent? If it's the button, then look at its Caption property.

I've never use borlands object library - I used their compiler way back when in my 16bit days (ie, up to 1999), so take this next bit under advisement.
In raw windows (which I bet Builder sits on top of):
A button (or any other control) has an ID, which is set when the button is created (CreateWindow parameter), or later (with ::SetWindowLong(hWnd, GWL_ID, nID) )
When a button is pressed, it sends a WM_COMMAND message, and one of the parameters has the ID number embedded in it.
MFC has message handlers of the form:
ON_COMMAND_RANGE(ID_FIRST, ID_LAST, MemberFunction)
where function is of the form:
void CMyDlg::MemberFunction (UINT nID)
so your function can tell different controls apart.
I bet you'll find that TButton inherits from something like TWnd, which will have a SetDlgCtrlID member function, and it has some sort of message routing table.
Iain.

Hi all..
I'm creating the window with the help of CreateWindowEx. And i'm making it transparent.. And i'm drawing PNG on that window.. Now i need to repaint it whenever any window is dragged to it. As soon as any of the window dragged on it my WM_PAINT should get called. How do i do that?
Thanks.

May be you can handle WM_WINDOWPOSCHANGED message?
Regards,
Sandip.

That will just call when my window changes.. I need to get notify when other window move on to my window.. Hope you're getting my problem.
Thanks.
