They are many licensing mechanisms available, both free and paid. Have you done at least a cursory search?

Yes a bit. But I'm not really sure what to look for. Never done this before.

Provide the registration file with the DLL or as an embedded resource. 
|
|
|
|

I considered that, but then I would have to recompile the DLL for each client.

No you wouldn't. Everyone can use the same one.

FYI, there have been threads in the C# forum for how to dynamically inject a resource into a DLL. I forget the exact approach, but I participated in just such a thread, so I know there's an answer here somewhere if that's what you want to do.

I've been trying to figure this out for over an hour and haven't had any luck. While doing a string comparison, this works but is case sensitive ... I'd like to make it case insensitive, any ideas on how to do this?
while ((line = file.ReadLine()) != null)
{
if (line.Contains(searchString))
{
textBox12.Text += "Line Number " + counter.ToString() + ":" + "\r\n";
textBox12.Text += line + "\r\n";
textBox12.Text += "\r\n";
}
counter++;
}
Complete function
if (checkBox1.Checked == false)
{
foreach (string i in xmlFileNames)
{
FileStream fs = new FileStream(@i, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
StreamReader xmlStream = new StreamReader(@i);
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(fs);
string allRead = xmlStream.ReadToEnd();
string line = null;
int counter = 0;
string testString = Regex.Match(allRead, searchString, RegexOptions.IgnoreCase).ToString();
if(Regex.Match(allRead, searchString, RegexOptions.IgnoreCase).Success == true)
{
System.IO.StreamReader file = new System.IO.StreamReader(@i);
while ((line = file.ReadLine()) != null)
{
if (line.Contains(searchString))
{
textBox12.Text += "Line Number " + counter.ToString() + ":" + "\r\n";
textBox12.Text += line + "\r\n";
textBox12.Text += "\r\n";
}
counter++;
}
}
xmlStream.Close();
}
textBox12.AppendText("Number of xmls listed: " + xmlFileNames.Count().ToString());
}

Unfortunately, the Contains method does not support any of the StringComparison overloads that othr methods do.
The workaround is to use IndexOf which does:
if(line.IndexOf(searchString, StringComparison.OrdinalIgnoreCase) >= 0)
{
...
}

That worked well, thank you

Bad idea when working with non-Latin General char sets.
|
|
|
|
|
I know, but most people would have used it and moved on. And maybe sought/asked for a better solution later.

First define an IEqualityComparer like this:
class CharEqualityComparer : IEqualityComparer<Char>
{
bool ignoreCase;
pubilc CharEqualityComparer(bool ignoreCase)
{
this.ignoreCase = ignoreCase;
}
pubilc CharEqualityComparer() : this(false);
{
}
public bool Equals(Char c1, Char c2)
{
c1 = (ignoreCase) ? c1.ToString().ToLower().ToCharArray()[0] : c1;
c2 = (ignoreCase) ? c2.ToString().ToLower().ToCharArray()[0] : c2;
if (c1 == c2)
{
return true;
}
else
{
return false;
}
}
public int GetHashCode(Char c)
{
int hCode = (int)c;
return hCode.GetHashCode();
}
}
and then do this in your code
if (line.Contains(searchString, new CharEqualityComparer(true)))
Hope this helps!
Cheers

That looks correct but expensive, as each pair of characters may result in the creation of several string objects.
The community content on MSDN[^] suggests another approach.
|
|

Just to enhance upon this solution, instead of doing a ToUpper/ToLower, you can use String.Equals with a StringComparison overload:
public bool Equals(Char c1, Char c2)
{
var comparison = (ignoreCase) ? StringComparison.OridinalIgnoreCase : ? StringComparison.Oridinal;
return String.Equals(c1.ToString(),c2.ToString(),comparison);
}

Thanks for that info!

Write an extension method that overloads the string.Contains() method.

Hi
I need to play(render) a video stream from an IP camera. Since media element does not support rtsp protocol, I created a rtsp client which connects to the camera. Now I am not sure what to do with that stream? My best guess is to save it file, and than use media player to render it. Does anybody knows how to do that? What I am concerned is, when to delete old data from the file and how can the same file be opened for reading and writing at the same time? If anybody has any ideas how to solve those problems, please let me know.

That app. just downloads a jpeg and renders it - in my case I access a 3GP encoded file.

Hi
In my c# windows application I have a registration form having dropdown of Country, State and City fields.
I want to fill these dropdown from web as I don't want to fill them from database or any hard coded values. Is there any web service which provide the Country, State and City related updates or Is there any other way to Implement this?
Please Help..
Thanks in advance

I also found this link but here I didn't found the way to get City an states corresponding to that country.
I know I can also get list of all country using culture info in c#. But still unable to get list of state or city.

Don't; they'd be too long. Simply allow the user to type the input and then validate it. Drp down and such are for when you have a very few, lengthy, entries.
