I have a service that opens a listening tcp socket and cant get connection from remote pc. No problem with local connection.
It works fine as console app.
I tried using networkservice, localservice, localsystem but none worked.
I dont know if it works as user service - problem installing the service, with invalid user or password error although im using administrator account and have password.
Firewall is off, but should not be a problem since it works as console app.
Am I missing something?

do you log occurred errors?
what error do you have?

There is no error messages. The socket can listen, but from the network, it seems that no port is listening.

I would like to ask what's the best way to change content of main form. I have 3 items in menu strip (Add user,Delete user,List of users) I don't want to open new window after clicking on menu strip item but i want to have only main window and change content. Thanks

You could put your subforms in User Controls, then just show the appropriate one when the proper button is clicked.

you can use what Dave said, otherwise use a classic ways, make visible/invisible panels that contains your sub form
hope it helps

Hi All,
I've just been working on some drag and drop functionality in a C# app and came upon this exception:
Invalid FORMATETC structure (Exception from HRESULT: 0x80040064 (DV_E_FORMATETC))
This was occuring when debugging ... I would drag the item out of my app and hover over the related app in the taskbar in order to restore that apps screen to drop the item in the other application.
So I rebuilt the entire application in Release mode to test the same thing there and there is no problem. After reading a bit it seems that this is actually related to protected memory. Can I just put this down to the app being in debug mode and rest easy that it works in Release mode?
Kinda worrying when your app behaves better in Release mode ... there is always a first I guess

Did the error occur if you executed the Debug build without Debugging?

Interesting. I didn't think to try at the time, so I just did ... no error ... it must be related to the debugger.

How extensively are you using generic methods in your codebase? I've gone through some simple implementations like creating a generic Max() method to get the max value of different integral types.
I'd like to know the extent of the practical generic method implementations you are using in your codebase.

Extensively. I use them extensively.

I use them extensively where appropriate.

I have two PC screens, one DVI is my main screen and I can also plug a VGA screen. I wonder if, just say, I put a PictureBox on a Form, and when I exacuate the program, the content of the PictureBox will show on my VGA screen in a fullscreen mode; while on my main DVI screen, it remains a square PictureBox on a grey Form?
Thank you.

Is it VGA vs DVI, or primary vs secondary monitor?
I never encountered this in my programming, but I've ran into some video playback apps and codecs that only worked on the primary display and not the secondary.
Today's lesson is brought to you by the word "niggardly". Remember kids, don't attribute to racism what can be explained by Scandinavian language roots.

primary vs secondary, just as if the thumbnail of the secondary screen is showed on the primary screen in real-time.

That's going to be a bit difficult to pull off. You have to get the screen rectangle, then take a BitBlt copy of that rectangle every so often, then draw it in your PictureBox. Since a 1280x1024 screen, at 32-bit depth, is 5.2MB. At 30fps, that's 157MB per second of data you have to move. That's going to eat some serious CPU.

Thank you, but I think this is not the case. Since video card can split a single video output signal to 2 different screen simultaneously, I wonder if there is a way to project one to a 'fullscreen' and another to a picturebox, as if the picturebox is a 'independent screen'.

No, there isn't.

You can use the Screens collection to work out what screen you're on, you can't work out if one is DVI and one is VGA ( whatever you mean by this )

hi guys, I need to clean up a string what this function below does but sometimes this is too slow and I have been told that for best performance regular expression will do much a faster job. Is there anyway to write a regulatr expression that cleans what the function below does?
Please help guys!
Thanks
Frank
private string CleanString(string strValue)
{
// See Above CString() Function for ASCii Denotations.
string strReturn = strValue;
for(int x=0; x < strValue.Length; x++)
{
char charTmp = strValue[x];
string strTmp = charTmp.ToString();
int ASCii = (int)charTmp;
// The following blocks system characters (<= 31) save for the
// CR (10) / LF (13) needed to preserve Line Returns. It also clears
// some specific problematic characters, such as double quotes ("),
// semi-colons (;) and html-tag delimiters (<) and (>).
if ( (ASCii <=9) || (ASCii == 11) || (ASCii == 12) || ( (ASCii >=14) && (ASCii <=31) ) || (ASCii == 34) || (ASCii == 59) || (ASCii == 60) || (ASCii == 62) || (ASCii == 124) )
{
// Strip out these characters as they're encountered...
strReturn = strReturn.Replace(strTmp, "");
}
// This next step eliminates the ever-annoying shift-space character
// as well as a large range of non-used symbol and system characters.
if ( ((ASCii >=127) && (ASCii >= 191)) || (ASCii == 215) || (ASCii == 247) )
{
// Strip out these characters...
strReturn = strReturn.Replace(strTmp, "");
}
}
return strReturn;
}

a regexp like [\x00-\x09\x0B-\x0C\x0E-\x1F\x22\x3B\x3C\x3E\x7C] which is equivalent with if ( (ASCii <=9) || (ASCii == 11) || (ASCii == 12) || ( (ASCii >=14) && (ASCii <=31) ) || (ASCii == 34) || (ASCii == 59) || (ASCii == 60) || (ASCii == 62) || (ASCii == 124) )... hope i didn`t omit any of the ascii numbers or miscalculated their value 
Code? Yeah i love it fried together with a glass of wine.

Looking at this gives me flashbacks...
You should think about using a regex util. I use 'The Regex Coach.' If it's a performance increase you should first consider rewriting the nasty looking conditional(s). Be aware that regular expressions can be a huge pain (and hurt performance) if done poorly.

I think first of all you need to quantify what you mean here and have a way of timing a simple loop to cleanup the strings. I would have done much the same but in c++ I would have done something like :-
template <class T>
class is_garbage: public unary_function<char, bool>
{
public:
bool operator ()(T t) const
{
return ( !(isalpha( t ) || isdigit( t )));
}
};
std::string clean(const std::string& val)
{
string tmp = val;
string::iterator it0= remove_if(tmp.begin(), tmp.end(), is_garbage<char>());
string result(tmp.begin(),it0);
return result;
}
Which isnt that much different from what you've got, a bit more readable maybe 
(NB : you would have to alter 'is_garbage' to match what you want, this is straight from my code, Ive made no attempt to replicate your issue)
Are you actually searching for strings within strings, replacing etc ? no ?? then I personally think a regex is an overkill ...
Ive copied this excerpt from John Maddock's page where he has the Regex++ library, although its been in Boost for a while now :-
"Regular expression libraries use a variety of differing algorithms all of which have their pro's and con's, which can make it hard to choose the best implementation for your purpose. This library uses an NFA algorithm which is dedicated to determining fast and accurate sub-expression matches, as well as providing support for features like back-references, which are hard to support using DFA algorithms.
People who should use this library:
Anyone who needs to use wide character strings.
Anyone who needs to search non-contiguous data.
Anyone who wants fast sub-expression matching.
Anyone who wants to customise the regular expression behaviour, or localise the library to a non-English locale.
People who should look to an alternative DFA based library:
Anyone who doesn't care about sub-expression matching, and
Wants to search only ANSI-C strings. " ref http://ourworld.compuserve.com/homepages/john_maddock/regexpp.htm[^]
