There is only 1 control in my dialog which catches (and thus shows) a tooltip.
Does that imply that OnToolTipNotify() is called only for that one control? Are the other controls obscured by anything, including a group box?

Well now you mention it: yes, they are all surrounded by a groupbox.
(that one control isn't surrounded)
I didn't know that that would be problem?
Why's that?

The group box control needs to be behind the other controls. Even though it appears as a skinny line surrounding the controls, it is actually obscuring them as far as tooltips are concerned. In the resource editor, change the tab order of the controls such that all the controls within the group come first.

Hi,
tnx for your reply, but I'm afraid the changes didn't make any difference... 
Oh well if it doesn't work, the boss must be happy without.;P

If you can trim the code down to something very small and still be able to reproduce it, feel free to send the project to me and I can take a look.

I see your point. If I make the Group box invisible, the tooltips appear.
However the three groupboxes in my dialog have the three last numbers of tabstop and the tooltips do not appear. (enabling or disabling the tabstop propetie does not help)
(why don't things ever go the easy way  )

There's no need to make it "invisible." Just ensure that it is behind all the other controls.

I don't quite understand this.

Hail everyone,
Let's say I have two classes, A and B, as well as two interface (abstract) classes for them, iA and iB. Class B derived from class A and interface iB, interface iB derived from iA, so we have,
class iA {
vitrual method AA
}
class A: public iA {
method AA
}
class iB: public iA {
vitrual method BB
}
class B: public A, public iB {
method BB
}
By doing this I want to be able to access methods of class B (and A in it) through interface iB, but, I can't do so. Compiler justly says "pure vitual function AA was not defined in B"
So, couls you please explain to me how this hierarchy should look like?
Thanks in advance, any suggestion would be helpful.

Because class B inherits from both class A and class iB, it has to deal with two different vtables. Therefore you need to provide method AA of class iA in both vtables and that is the source of the error message: the implementation for class iB is missing.
Just write a wrapper method AA in the class B, calling A::AA; this will redirect iB::AA to A::AA.

We are trying to capture ctrl + char keys from keyboard for the list control. We are not able to get good help. We even tried with lvn_keydown but not working. Is there a way to find the solution.
Thanks & Regards,

Processing the LVN_KEYDOWN notification will work, I've tested it. You just need to check if ((LPNMLVKEYDOWN)lParam)->wVKey=='F' and then check the state of the control key, it is pressed when the test (GetKeyState(VK_CONTROL) >> (sizeof(SHORT)-1)) returns non-zero.

{<br />
SHORT nCtrlState = GetKeyState(VK_CONTROL);<br />
if(nCtrlState && pMsg->message == WM_CHAR)<br />
{<br />
}<br />

how can i know the NIC number of network card using winsock or any other method
C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do, it blows away your whole leg

When you say NIC number are you looking for the MAC address? If so you may want to check out this.[^]

Hi all,
i like to deactivate my Dialog Button IDC_STOP_ROBOT.
Seems like no big deal, but when useing the syntax below nothing happens?
GetDlgItem(IDC_STOP_ROBOT)->EnableWindow(FALSE);
.. or enable again:
GetDlgItem(IDC_STOP_ROBOT)->EnableWindow(TRUE);
happy coding,
-mark

CWnd* pWnd;<br />
pWnd = (CWnd*)GetDlgItem(IDC_STOP_ROBOT);<br />
pWnd->EnableWindow(FALSE);
AND
CWnd* pWnd;<br />
pWnd = (CWnd*)GetDlgItem(IDC_STOP_ROBOT);<br />
pWnd->EnableWindow(FALSETRUE);
if it doesn't work try rebuilding all.
(now I noticed it's actually the same...   )
Hope it helps.

At what point(s) are you calling EnableWindow()?

Hi All,
Using VSFlexGrid.
I want a combobox in 1 cell to be only readonly.
In the Beforeedit event,I set the cancel to "true".
In the OnClick event,I have this.
std::string test("|Hello|Text|test1");
m_flexGrid.SetComboList(test.c_str());
But I couldn't see the combobox dropdown list.
Would be nice if u could help me...
Thanks...

I'm using CHtmlView in my application to display html's store on the local machine. But when i navigate to some locla page sometimes the images there are not displayed. The image path is correct. It's something like "c:\images\image.jpg". Where is the problem. In caching, in backward slashes?
|
|

|

Hmm... interesting.
I once wrote a program that stored the HTML sources inside the rc-file, worked fine for HTML, didn't worked at all for jpg's. So I put the jpg's in a relative adress to the program -> wokred fine.
In other words, the problem you are describing here worked fine back then when I tryed it (VS6 a few years ago), so I guess the problem lies in the HTML-Source.
Can you please post the HTML-Source around the problem? (right click, view source when the program is running.)
|
|
|
|

Thanks for the quick answer.
I can't put the HTML in res-file because it's dynamicly created and also i can't use relative paths but abosolute bacause the paths are also dynamic. The HTML for the images is:
It works but when i right click and refresh the page sometimes some of the images doesn't appear. This is inexplicable for me.

How should the assignment operator be written for the following class?
<br />
class CTest<br />
{<br />
private:<br />
const int m_test;<br />
<br />
public:<br />
CTest(int i) : m_test(i)<br />
{<br />
}<br />
<br />
CTest(const CTest& rhs) : m_test(rhs.m_test)<br />
{<br />
}<br />
<br />
~CTest()<br />
{<br />
}<br />
<br />
CTest& operator=(const CTest& rhs)<br />
{<br />
}<br />
};<br />

CTest& operator=(const CTest& rhs)
{
m_test = rhs.m_test;
return *this;
}Yes, you can see the private members of another instance of your class. Returning a reference to the current object allows assignments to be chained.
Interestingly, even though you haven't written an operator=(int), because you have an implicit constructor that takes an int, you can write:
CTest tst( 4 );
tst = 9; which constructs a temporary CTest and calls operator=. If you don't want this, mark your constructor explicit.
Stability. What an interesting concept. -- Chris Maunder

Thanks for trying to help but the member variable is a const int which generates the compiler error 'l-value specifies const object' if I implement your suggestion. The class shown is just the simplest example I could put together to show my problem.

My understanding is that the only time a const member variable can be initialized is in the member initialization list of the constructor. So unless you are just trying to solve a puzzle for a class, I wouldn't try to get around this rule in professionally designed code. If the variable is const, it is const for a reason; meaning it should never change once it is initialized. Once it is initialized by the constructor, whether it be the default constructor or the copy constructor it should never be changed!! That is why it is const. If it needs to be changed then it should not be const. It is as simple as that in my mind.
Now some super programmer might reply with some crazy way of actually making it happen; but again, it is not good programming style. Const has a special meaning and to make a member variable const and then try to undo that is a bad style in my opinion. Either the variable needs to be const or it doesn't! Since const variables must be initialized in the member initialization list of the constructor anyway, there seems to be no reason why you'd ever want to copy it in the assignment operator anyway because the value would be the same for all classes anyway!
Regards,
Shawn
