No sorry this is not my point. This will not add a notification if the user clicks on the "Popup" item. This will only change the behavior when clicking on "real" menu items.

Hi.
In my application I have added a listbox on a dialog box. This list contain numbers of elements that user has to scroll so much to see all the contents.
I want to minimize the scrolling efforts of user and I want to provide auto scrolling to the list box. The elements of the list box should get scroll automatically when user movies the mouse pointer over scroll bars of the list.
How I can proceed to achieve this?
Thanks

What would be the difference between an registered dll and a normal dll that doesn't have to be registered, would there be any performance differences?
Many Thanks

Assuming the DLL's are the same as far as their core code is concerned, No.

Yes the code would be the same ... Thanx for clearing that one up John.

Normal dll should be present in Exe Current Directory or environment path.. but no such compulsion with registered dll as it path is stored in registry

So that is the difference between the two? (in a nutshell)
Thanks for the response.

Hello,
I have a Dialog, where in I show some text and draw some images using DrawText() and Draw(..) functions respectively.
Now I need to introduce an IEControl on this dialog. I wish the IE control to behave as if, its the background of my dialog, i.e. when I draw text on my main dialog, some part of the text is present on the main dialog and some part of the text spills over the IE control(this behavior is desired.) however, I wish to show my text in the foreground and the IE control to be on the background.
However windows is not providing any APIs for definind Z-Order for a child window and the text out on the dialog.
Any pointers in this regard will be highly appreciated.
Thanks
Suyash

No, there's no Z-order for drawing on a window. It's up to you to make sure you draw on top
of whatever you want the text to be on top of.
I'm not sure what "IEControl" you are using so I'm not sure how you could potentially know when
it's appropriate to draw the text.

What is difference between File pointer and File Descriptor?
|
|
|
|
|
a file descriptor is an unique number managed by the system itself to identify the file opened.
in your code, you don't get it. you get a FILE* (file pointer) to a copy of the opened file mounted in memory
you actually never work directly on the hard disk file, but on its copy into memory

Hi guys
I'm trying to figure out how to make a template class History. This class should be able to record history moves.(for any application). e.g. a history of changed in an editor, or a history of URLs in a web browser etc.
This is what i came up with so far.
<br />
#include < stack ><br />
#include < iostream ><br />
#include < string ><br />
<br />
using namespace std;<br />
<br />
template < typename E > <br />
class history<br />
{<br />
private:<br />
stack < E > back_list; <br />
stack < E > forward_list;<br />
<br />
public:<br />
history();<br />
void add_entry(const E & entry);<br />
E & undo();<br />
E & redo();<br />
bool no_undo();<br />
bool no_redo();<br />
};<br />
<br />
template < typename E ><br />
void history < E >::add_entry(const E & entry)<br />
{<br />
back_list.push(entry);<br />
while(!forward_list.empty())<br />
{<br />
forward_list.pop();<br />
<br />
}<br />
}<br />
<br />
template < typename E > <br />
E & history < E >::undo()<br />
{<br />
E entry;<br />
if(!back_list.empty())<br />
{<br />
entry = back_list.top();<br />
back_list.pop();<br />
forward_list.push(entry);<br />
<br />
}<br />
<br />
return(entry);<br />
}<br />
<br />
template < typename E > <br />
E & history < E >::redo()<br />
{<br />
E entry;<br />
if(!forward_list.empty())<br />
{<br />
entry = forward_list.top();<br />
forward_list.pop();<br />
back_list.push(entry);<br />
}<br />
return(entry);<br />
}<br />
<br />
template < typename E > <br />
bool history < E >::no_undo()<br />
{<br />
if(back_list.empty())<br />
return(1);<br />
else return (0);<br />
}<br />
<br />
template < typename E > <br />
bool history < E >::no_redo()<br />
{<br />
if(forward_list.empty())<br />
return (1);<br />
else return (0);<br />
}<br />
<br />
<br />
<br />
void main()<br />
{<br />
history <int> his;<br />
his.add_entry(2);<br />
int out;<br />
out = his.undo();<br />
cout<<out;<br />
<br />
}<br />
<br />
I get no compilation errors but as soon as i try to run it i get:
<br />
Linking...<br />
history.obj : error LNK2001: unresolved external symbol "public: __thiscall history<int>::history<int>(void)" (??0?$history@H@@QAE@XZ)<br />
Debug/history.exe : fatal error LNK1120: 1 unresolved externals<br />
Error executing link.exe.<br />
<br />
history.exe - 2 error(s), 0 warning(s)<br />
Any ideas of i'm doing wrong?
It's the first time i'm using template so i'll appreciate any help.
Thank in advance.

you don't define a constructor for you class maybe, no ?
also next time, please use the <pre></pre> tags, and replace the < and > with < and >

Hi toxcct
Thanks for helping me. Sorry about my post it was missing all the <parts>.
U r right i don't define a constructor. Think thats why i get the errors?
The default constructor history() won't do the job?
Thanks again toxcct

yes, that's exactly what the error message talks about :
unresolved external symbol "public: __thiscall <code>history<int>::history<int></code>(void)"

Yes, you have forgot to define this c'tor.

I'm so stubit guys.
You were right i forgot to define the constructor outside the class.
It works fine now cheers everyone.
Appreciate ur help

Hi,
How can I change the height of a dropdown/droplist combo box (not the height of the dropped listbox)? It is automatically set by the font size.
Thank you.

Have a look at CComboBox::SetItemHeight.
If you want to increase dropped height, you need to increase reactangle heigh bounding it, i.e. reactangle you have mentioned while creating combobox, or use MoveWindow to mention increased height.
|
|
|
|
|
No... I mean the height of the combo box window.
