I like listbox because of its simplicity. But could you please point out the advantage of listctrl that made you to ask so?

Instead my choice is Listctrl and ListBox is simple to use but its limited.

Because all I need is a list of names.
CListCtrl has been designed to do more, like icons, different views(like report), good in-place edit, etc. and more flexibility cause more complexity, so one should spend a lot more time and write more codes to do the same work that could be easily done by a ListBox.
Now that I don't need those features, why should I go the hard way?

I agree. It was an odd suggestion.

Your method seems fine to me - but have a look at LBS_HASTRINGS to be sure.
My suspicion is that the example snippet is just storing a pointer to some text in itemData in order to have something simple to draw. There's nothing to stop you have your code numbers in it, or neglecting it completely.

I try to subclass and use this code for change background color in list control
<br />
BOOL CSubListCtrl::OnEraseBkgnd(CDC* pDC) <br />
{<br />
CRect rect;<br />
GetClientRect(&rect);<br />
pDC->FillSolidRect(0,0,rect.Width(),rect.Height(),RGB(100,200,0));<br />
return TRUE;<br />
}
it work only when first time show.
but when I add item to it, that item will change to default color.
Please help me for solve this problem.

I think you should override DrawItem which will be called when each item of the control is to be drawn. Then use the input parameter for that function(lpDrawItemStruct) like this:
CDC dc;
dc.Attach(lpDrawItemStruct->hDC);
dc.FillSolidRect(&lpDrawItemStruct->rcItem, RGB(100,200,0));
dc.Detach();
You should also manually draw text of each item, check to see if it is selected to highlight it and draw a border for active item.
By the way if your list control is inside a dialog, take a look at OnCtlColor of the dialog. It makes life times easier if you just need to change background or text color of a dialog control.

I wonder why you do such a thing when SetBkColor and SetTextBkColor are available for CListCtrl.

But he needs a single bk color. So my suggestion is good, right?

I didnt see your answer but I see your answer yeah its good and perfect.;) but he must tells more detaily of his control.

scanf consider space bar as an end of input just like an enter key(carriage return), is it possible so that it shouldn't consider space bar as an end of input.
|
|
|
|

does this works for you
char vl_sData1[111],vl_sData[1233];
sprintf(sData,"Hello World\n")
sscanf(sData,"%[^\n]" , vl_sData1)
|

You are only partialy correct. When scanf() is processing a %s format specifier, it will continue until it encounters a whitespace character. If there are any more format specifiers, those will then get processed.

Use gets() function.
It will scan the string till you will press enter key.

Hi,
how does "sizeof" operator works internally?
Thanks

The compiler "knows" the sizes of all types that are native, or have been declared up to that point. It merely substitutes an integer constant in place of the sizeof expression at compile-time. Unless you're talking about reflection or RTTI (run-time type identification), all the size information is known at compile time, so there is no run-time involvement; just a simple substitution. Much like using a #define or a const.
Hope this helps.

I do not know a way to get all exceptions.
try
{
}
catch(CException *e){}
is not working for all exceptions. If I put catch(...) it is ok but I cannot get the error message this way.
Do you know what I can put in the catch () so that I can handle all exceptions having their messages.
Thank you!

In order to catch everything, you need to look at the docs for the function which is throwing the exception and then add a catch statement specific for that.
try<br />
{<br />
}<br />
catch(CException *e)<br />
{<br />
}<br />
catch(LPTSTR szErr)<br />
{<br />
}<br />
catch(...)<br />
{<br />
}
