There is no standard directory listing method in the HTTP protocol. Directory listing is usually disabled (security hole) for most if not the whole site and even if its enabled you get back an index file if present (like with http://my.lotro.com/home[^]). Even if the get on the directory returns a directory listing its still a non-standard generated html page that you have to parse somehow. Its a waste of time trying to solve this problem because this can not be solved. Web spiders just follow links found on websites, they do not do directory listings.

Hi guys,
For our company I have written (meanwhile some 15 years ago!) a data mapping tool. This tool has evolved over the years and it is currently in C++, using Microsoft Visual Studio 2010. One of the products for this tool is a debugger that shows what is happening and shows the source code lines where action is performed. This part uses a CEdit control.
We have included stuff like breakpoint markers and all that.
Recently I have come to think that it might be handy to introduce syntax highlighting for the source codes. Would anyone have any samples of a CEdit that can do that sort of thing (like changing the color of words, showing them in bold or italics and stuff like that) Would save me a lot of re-inventing the wheel!
Thanks in advance for any suggestions.

I think the best solution would be to replace the CEdit control by a CRichEditCtrl. It can do all the things you want.

I created an SDI application with FormView. I fixed the main window size to 600*350 and placed the control over the dialog accordingly and it worked fine.
But now I magnified the screen (Control Panel\Appearance and Personalization\Display) to 125% on my win7 machine. Now my application dialog is adjusted as per windows magnifier but main windows(mainframe) size remains small (600*350) and FromView inside the mainframe is not completely visible.
Please guide me to solve this issue.

It is a known issue. MS has developed a guide (TL;DR)[^] that is in their mind supposed to assist the developers.
In short, try first to adjust the manifest settings, as they suggest in the article and see if it works, otherwise, it is a notorious task of testing and adjusting, especially is you use custom fonts

Hello friends
I converted a Mfc project from VS2005 to VS2010.
Its compiled successfully.Now,the prob is that I am not able to launch application through release build output As It is opening through Debug Build output.
Any Ideas ?
Thanks & Regards

Create the release version and launch it. Your question makes no sense, you have to choose the Release build as opposed to the Debug version.
One of these days I'm going to think of a really clever signature.

Perform a clean build on both release and debug. Then rebuild the solution in release and launch it. The clean operation already wiped out the debug binaries, so you will either get an error or the app will be launched in release mode.

Hello Guys
Thanks for ur reply. Prob Solved.

Here is some code from the draw function in my custom control. I am using a vector to contain data concerning portions of the control.
This code works. You will surely agree with me, though, that using the iterator 'x' to identify vector members in called functions is probably a tad on the clunky side. I have had a go at sending pointers to vector members. I gave up with this. I think this might not be the right way to go either. What it is the correct, elegant way to do this?
vector<sliderUnit>::iterator slider;
for ( slider=sliderVector.begin() ; slider != sliderVector.end(); slider++ )
{
theSliderRect.left = theDrawRect.left+(x-2)*sliderWidth;
theSliderRect.right = theSliderRect.left + sliderWidth;
(*slider).m_TextBoxSize = m_TextBoxSize;
(*slider).sliderRect = (RECT)theSliderRect;
tempRect=theSliderRect;
tempRect.right=tempRect.right-4;
DrawBackground(&theMemDC,tempRect);
if (m_currentSlider != x-1){
(*slider).m_bFlashFocus = FALSE;
}
else{
(*slider).m_bFlashFocus = TRUE;
}
DrawButtonsByID(&theMemDC, theSliderRect, x-1);
DrawThumbSliderByID(&theMemDC, theSliderRect, x-1);
DrawSliderLabelByID(&theMemDC, theSliderRect, x-1);
x++;
}

Huh?
What type is "X"? I assume it is an int (or long) since you add it to a CRect internal value.
In what way does it identify a vector element? it is not clear.
Nihil obstat

|

|

Sorry, I should have clearer. The function calls I refer to are at the bottom of that block of code
DrawButtonsByID(&theMemDC, theSliderRect, x-1);
DrawThumbSliderByID(&theMemDC, theSliderRect, x-1);
DrawSliderLabelByID(&theMemDC, theSliderRect, x-1);
The 'x' becomes 'id' in the called function below which dereferences the vector member that is the same as the iterator in that first for loop block I posted. I know this is murky. That's why I want to make nicer.
void CScrollBarEx::DrawThumbSliderByID(CDC* inDC, CRect inDrawRect, short id)
{
CRect theThumbSliderRect;
COLORREF theThumbSliderColor = GetSysColor(COLOR_3DFACE);
COLORREF theThumbSliderTextColor = GetSysColor(COLOR_WINDOWTEXT);
ASSERT(inDC != NULL);
if (sliderVector[id].m_bThumbSliderDownFlag && sliderVector[m_currentSlider].m_bTrackThumbSliderFlag)
{
theThumbSliderColor = sliderVector[id].m_ThumbSliderTrackColor;
theThumbSliderTextColor = m_ThumbSliderTextColor;
}
...

So you're accessing a vector with an index that comes from a variable of unknown type and origin. Not a lot of information to work with. Why do you think this is a problem? Is there a reason why you think x is not the appropriate index to use?
Until you explain what x is and where you got it from, it's hard for us to understand your problem - if there is one. Since the code works, the only suggestion I can make at this point is to rename x to something more ... self-explanatory, and add a few comments to explain what's going on (while you're still able to understand it). That may be helpful if you need to fix it in a year or two.
P.S.: There's one other suggestion I can think of: instead of passing x to those functions, pass a reference to the vector element. While technically that is the same as passing a vactor index, it removes the dependency between those functions and the entire vector.

I have spent some time trying to write code to send a reference to the vector element. I think I might have had trouble extracting this from the iterator. I must have somehow persuaded myself that there was some reason as to why passing a reference to a vector element from an iterator was a bad idea. I was just wondering if anyone knew if there is some sort of trap here - . I would probably be happier doing it this way if it is straightforward and safe. It seems more elegant. I don't really want to get bogged down in making the changes, though, if there is some inherent problem.
The functions in the iterator block use and possibly change the data in the vector element but don't call any further functions that use the vector element. There is only a single thread accessing the vector.

You didn't use an actual iterator anywhere in the code that you posted, so I don't see the problem. When a function argument is declared as a reference, you can just pass a vector element, such as sliderVector[id]. If you do have an iterator, then you can just dereference it to get the vector element and pass that instead. If you wish to pass a pointer instead, just use the 'address-of' operator:
void bar_ref(double& element) {
element *= 2.0;
}
void bar_ptr(double* p_element) {
*p_element += 3.0;
}
void foo() {
std::vector<double> myvec(2); myvec[0] = 3.1415;
myvec[1] = 2.718;
for (std::size_t i = 0; i < myvec.size(); ++i) {
bar_ref(myvec[i]); bar_ptr(&(myvec[i])); }
for (auto it = myvec.begin(); it != myvec.end(); ++it) {
bar_ref(*it); bar_ptr(&(*it)); }
}
The only possible trap I see is trying to pass an iterator directly when a pointer is expected. An iterator may behave like a pointer, but, while - depending on the implementation - it may actually auto-convert to a valid pointer (I know VS 2003 did that), you shouldn't rely on that. (e. g. VS2010 doesn't accept it)

Thanks for this! I will certainly give this a go and let you know how I get on. It might not be for a few weeks, though...

Thanks very much for showing me how this can be done, Stefan. I have tried your method and it works perfectly.
I have thought some more about what I'm trying to achieve, though, and have come to the conclusion that since the vector array has class scope and that its members don't themselves know, or need to know, whether they are the current item in the 'for' block (where I've got the iterator) - the more elegant solution would, I guess, involve just sending an (integer) identifier for the required element.
Your help is very much appreciated. Your correspondence has helped my thought process a lot.
Cheers,
Ben

Glad I could be of help.
As for your conclusion, keep in mind that sending an ID of the element requires you to also pass the container that this ID refers to! Otherwise the function won't know what to do with that ID. Whether that ID is an iterator or index value doesn't matter in this regard - neither have an inherent knowledge of the container they refer to.
If the container is class scope, and you pass an ID to a class member function, that would work. But from a design view, doing so would still be questionable as the function actually shouldn't need to care about the rest of the container - you have introduced an unnecessary dependency. If at some point you realize you want to use that same function for elements not related to this class, you cannot easily do it, due to that dependency.

hi all I wonder how comfigurar the code blocks for borland ide bcc55 and download the library QTK and c + + qt hope your help.

Get a time machine.
Dial up 1996.
Ask again when you get there.
Seriously, Borland C++ 5.5 is so out of date it's not worth thinking about. (But I loved it in its day.) There are much better modern compilers available for free.

You need to provide some more information on the problem. Is that the exact message that you see, and which DLL is it missing?

Hi all,
i make a nice CMyFileDialog derived from CFileDialog that works fine for my need, but i need just one function for my Dialog and this is when a user select some file in a list to catch this event, something like:
"OnItemChange", is this possible, something like CListCtrl function itemchange??? If yes can someone give me a suggestion how to do this?
