When it comes to the instalutil.exe - are you sure you opened the Command Prompt with path's set to the VS folders? Open the Command Prompt using the shortcut in the Visual Studio Tools in the start menu.
Start Menu >> Microsoft Visual Studio 2XXX >> Visual Studio Tools >> Visual Studio 2XXX Command Prompt

Hi, I have a class that triggers two different events.
- EventA triggers an event with argument AEventArgs
- EventB triggers an event with argument BEventArgs
Code sample below.
My question is:
How can I create one generic function TriggerEvent(...) that replaces TriggerEventA(...) and TriggerEventB(...) ?
class Publisher
{
public event EventHandler<AEventArgs> EventA;
public event EventHandler<BEventArgs> EventB;
public void TriggerEvents()
{
TriggerEventA(EventA, new AEventArgs());
TriggerEventB(EventB, new BEventArgs());
}
private void TriggerEventA(EventHandler<AEventArgs> eventHandler, AEventArgs args)
{
EventHandler<AEventArgs> handler = eventHandler;
if (handler != null)
{
handler(this, args);
}
}
private void TriggerEventB(EventHandler<BEventArgs> eventHandler, BEventArgs args)
{
EventHandler<BEventArgs> handler = eventHandler;
if (handler != null)
{
handler(this, args);
}
}
}
class AEventArgs : EventArgs
{
}
class BEventArgs : EventArgs
{
}
|
|
|
|
|
How about,
class Publisher
{
public event EventHandler<AEventArgs> EventA;
public event EventHandler<BEventArgs> EventB;
public void TriggerEvents()
{
TriggerEvent(EventA, new AEventArgs());
TriggerEvent(EventB, new BEventArgs());
}
private void TriggerEvent<TEventArgs>(EventHandler<TEventArgs> eventHandler, TEventArgs args)
where TEventArgs : EventArgs
{
EventHandler<TEventArgs> handler = eventHandler;
if (handler != null)
{
handler(this, args);
}
}
}You call it like TriggerEvent<AEventArgs>(EventA, new AEventArgs()) or without specifying the generic type. If type is not specified, compiler will infer from the type of parameter passed.

No, can't figure this out by myself...
I do have some dll's written in c++ which are part of a big project. Now I want to do a C# program that only display functions and parameters from a selected dll dynamically.
Tried some with LoadLibrary but can't get it to work. I won't call the dll code just need the info. Ideas?

For managed C++/CLI code, you could use reflection.
For native C/C++ code, the only way I see is by diving into the DLL file yourself, locating the EXPORTS table and mimicking the DUMPBIN utility (with option /EXPORT).

Hi,
How can i validate in .Net C# a SAML signature created in Java? Here is the SAML Signature that i get from Java:

I know to parse SAML, i need to validate the signature.
I tried this:
public bool VerifySignature()
{
X509Certificate2 certificate = null;
XmlDocument doc = new XmlDocument();
XmlElement xmlAssertionElement = this.GetXml(doc);
doc.AppendChild(xmlAssertionElement);
SamlSignedXml signedXml = new SamlSignedXml(xmlAssertionElement);
XmlElement xmlSignature = this.Signature;
if (xmlSignature == null)
{
return false;
}
signedXml.LoadXml(xmlSignature);
foreach (KeyInfoClause clause in signedXml.KeyInfo)
{
if (clause is KeyInfoX509Data)
{
if (((KeyInfoX509Data)clause).Certificates.Count > 0)
{
certificate = (X509Certificate2)((KeyInfoX509Data)clause).Certificates[0];
}
}
}
if (certificate == null)
{
return false;
}
return signedXml.CheckSignature(certificate, true);
}
It valides the signature of a SAML signed in .Net but not of this Java one.

Hi,
All previous replies lead to your local IP address, i.e. the address as seen on your LAN; when connecting to the Internet, the outside world may see you at a different address though, and you need an external server to tell you that address, have a look here[^].

Hi guys
So the past few weeks I've been doing research and playing around with TCP servers. I've finally got the one type of server architecture down and I understand the why's and the how's.
Basically the server object creates a TcpListener in its own thread to listen for client connections. When this listener thread accepts a client it creates a client object for it and handles communication(which is the blocking type) for that client in its own thread. So 1 thread per client.
I get that this doesn't scale well and why.
Now I need to move on to the non blocking way. I believe its called "asynchronous TCP sockets", using BeginConnect(), BeginAccept(), BeginSend(), BeginReceive(), EndConnect(), EndAccept(), EndSend()and EndReceive()
Now I've found alot of articles but what I really need is a bare bones example and explanation. Alot of these articles are built around custom libraries and implementations of this server architecture and I find it difficult to find the core concepts in between other code.
So my question, can anyone recommend an article where this is explained well enough and in a bare bones type manor? I'm really more interested in how it works instead of copying the code and modifying it for my needs.
Thanks

When creating scalable server applications, you should work directly with Socket class. If you need more, come up with a custom socket implementation which suits your needs. We did this once with an application. TcpListener or TcpClient are just wrapper classes built on top of Socket class. You will find it very limiting when you start coding with these classes.
Here[^] is my favorite article. I never found another one which is not even closer to this.
If you are doing serious coding, I would suggest to take a book rather than depending on several articles.

there is no way to change a single attribute in a css class in code behind.
how u can do it is either giv another css class or set a particular style attribute in code behind

i have created a dynamic 2d array using list<list <double="">> ....
now i want to convert this object into an actual array ?
how can i do that ?
bcoz the list.toarray can (i think convert it into a 1d array)???
 
|
|
|
|

Couple of things:
1) When you try to describe things such as List<T> please use the greater than and less than symbols just above - that way they don't get stripped out as HTML.
2) We would need more information. I am guessing that your "dynamic 2D array using list>" is actually along the lines of "List<List<string>>" but it could be anything really. We need to know what you are doing in order to help.
3) Check your post with the "Preview" button to ensure it looks like what you wrote! I keep forgetting...
