Hello Cedric,
thank you very much for your answer. i changed my array to a pointer array and now evertything works like it should. i knew the answer was pretty trivial but i somehow got stuck in the code 
i have have more and more to get used to the whole pointer and polymorphism stuff in c++.
@sashoalm: thank you for the link. when i have some time left i will have a deeper look on polymorphism...
regards,
rudi

Hi,
Is there any SDK or API which gives me the FILE Pointer to the file which is zipped inside another file. Basically I have couple of files which are winzipped and password protected. I want to FILE pointer to file which is inside the zip file. We have similar kind of functionality in sharpziplib which gives stream of file which is inside the zip file. sharpziplib is available in C#. Is there any SDK or libarary or API which is available to implement such kind of functionality in C++.
thanks,
Umrahi

I'm not sure about FILE* pointer, but if you want to extract the file see Minizip[^].

thanks for reply...
It seems it is not a managed code or compatible with visual studio 2008... Can you show me any library which is compatible with Visual studio 2008
thanks again

Anyone know a C++ function or library that can be used for percent decoding? I need a function that can take urls of the type "http%3A%2F%2Fwhatever.com" and turn it into "http://whatever.com". I searched on google but couldn't find anything.
I hope there is a standard function in some library (may be boost, I've heard it has nearly everything in it). But since URL decoding is a common problem there has to be some pre-cooked solution for it.
Write now I use code that I've written myself but it only works for 5-6 of the most common symbols, and it's definately not optimized!
std::string s2;
s2.reserve(m_RealUrl.size());
for (size_t i = 0; i < m_RealUrl.size(); i++)
{
if (m_RealUrl[i] == '%')
{
if (!strncmp(&m_RealUrl[i], "%3A", 3))
s2 += ':';
else if (!strncmp(&m_RealUrl[i], "%2F", 3))
s2 += '/';
else if (!strncmp(&m_RealUrl[i], "%3F", 3))
s2 += '?';
else if (!strncmp(&m_RealUrl[i], "%3D", 3))
s2 += '=';
else if (!strncmp(&m_RealUrl[i], "%26", 3))
s2 += '&';
else if (!strncmp(&m_RealUrl[i], "%25", 3))
s2 += '%';
i += 2;
}
else
s2 += m_RealUrl[i];
}

Try the Wininet[^] api, it has methods to canonize an URL, maybe it has something to do the job the other way too...

And if you're using MFC, there is AfxParseURLEx[^] function.
It is a crappy thing, but it's life -^ Carlo Pallini

I wrote this code
std::string url = "http%3A%2F%2Fsomething.com/index.php";
CString server, object, username, password;
DWORD service_type;
INTERNET_PORT internet_port;
AfxParseURLEx(url.c_str(), service_type, server, object, internet_port, username, password, ICU_DECODE);
But after the call to AfxParseURLEx both server and object are "". Is this the correct usage of AfxParseURLEx?

Is it really conceivable that the :// characters would be escaped? I just tried your code snippet with escaped characters in other parts of the URL and it worked fine.

Right click on this page and select View Source and scroll to the bottom. You may find an escaped URL hiding in there. Escaped URLs are very common in browser ads and malware for evading spam/ad-blocking technologies.
I'm not implying the purpose of the escaped URL on codeproject is for nefarious deeds!

Actually the URL that broke my code and made me start searching for a generic unescape function had :// escaped.

Fair enough. I just had never seen one.

Hi,
I'm back again with another question. I have a dialog which holds a tab control only. For each tab I created a dialog where I set the settings to border: no, style: child and control: on (Perhaps I used other words than the ones in Visual Studio because I use the german version)
So far this works just fine. I can open the different dialogs by selecting the adequate tab. Now I try to make a dialog on one of the tabs (let's call it dialog 1) which contains child dialogs (dialog 2) itself. I did everything like with the other dialogs, but I only see the controls which are directly on dialog 1, the dialog 2 is not there. My supposition is that it is either somehow hidden or behind dialog 1.
Anyone has an idea? Thank you.

if d2 is child of d1 it is in d1 and the controls of d1 will overlap d2. hide d1 (or the controls= and bring d2 to top.
If you use MFC you can build a propertysheet.

Hi KarstenK,
in dialog1 I have space reserved where I want to insert dialog2.
Dialog1 only contains two static texts and one GroupBox, I also tried both settings for the visibility but it didn't change anything.
I'm using MFC, but never came across those property sheets. Perhaps I can find the solution there.
Thank you so far.

Propertysheets are one of the best features of the MFC and really simple: http://msdn.microsoft.com/de-de/library/d3fkt014(VS.80).aspx
At the end of the site are links to samples. 
You make dialog-resource and create a CPropertyPage class with the wizard and call AddPage to a sheet...
