Has anyone got sample code of using Oracle and .NET?
I'm specifically looking for the syntax of calling a stored proc and receiving a result set.
Cheers,
Simon

oracle has recently released a beta version of their managed data provider. It comes with fairly extensive help files.
You may want to look into using that instead of the OleDb data provider.

I'm looking at the site now.
Any idea if there's truth to the rumor that Oracle can't return a recordset from a stored proc. to ADO?

Hi All,
I'm having a small problem with my C# application.
I have a DLL written a while ago, using pure Windows API. Now, it would be really nice if I could call functions of that DLL from my C# application.
Any ideas how I might go about it?
Any help would be appreciated.
Regards,
Venet.

i'm not an expert in dll-including, but i once took a function out of an ordinary dll like this:
[DllImport("user32.dll")]
private static extern bool SetForegroundWindow(IntPtr hWnd);
and just used it.
that was all 
:wq

|

Your best bet...
Put up the function call and we'll translate it for you.
It's incredibly easy with C# now. I've done about 20 of them so far and I'm really impressed with the robustness of them.

Thanks for your replies.
Basically the function contained within the dll is:
bool state;
bool InstallMHook(state);
And I have exported this function from mhook.dll.
So is this what I need to do:
[DllImport("mhook.dll")]
private static extern bool InstallMHook(bool someState);
as suggested by Rüpel ?

Venet.

I am trying to create a custom web control in C#. As i know, i can provide own property for user to set their prefer properties. Example:
public string Text
{
get{ return text;}
set{ text = value;}
}
But, the case is, i want to allow user to set multiple values for a property where user click on the the property window, it will be popping up a window and add the properties by using my own window setting. Is this possible to do and where can i find some example on this?
Thank you in advance

I am having problems finding out how to convert a time from a client's local time zone to GMT/UTC.
It seems the classes I should use would be in the .NET SDK for either System.TimeZone or System.Datetime. However, the .NET Framework SDK's System.TimeZone object does not have a public constructor (and is abstract) and the System.DateTime only creates its CurrentLocalTime according to the server the code is running on.
So, how do I create and specify another timezone? Most of the examples I have found either use JavaScript to display the value in the client's system time or use the standard offset for the client's timezone (which usually does not take into account Daylight Standard Time and the varying dates that the timezone switches to Daylight Time).
Any help is greatly appreciated. Thanks!

Hi...
so what is it this time 
This time I really would like someone, to explain how I store (and retrieve) bitmaps in a resource file....
Also: If I have a funktion to wich I want to send parameters, then how can I make a list appear, with the few diferant parameters I expect...
F.x.
call SomeMethod(Jump)// So when I want to send the paramet a list shows up with 5 differant options
private void SomeMethod(xxx usrAktion)
switch (usrAktion)
case Jump: etc;
case Walk: etc;
Please help, I will be greatful (honest)....

I'll help with the 2nd question:
If the parameter is of different types you can overload the method, just declare the same method with all the different paramaters.
If thats not really what you want your best bet is to use an enumerated type like so:
public enum UsrActions
{
Walk,
Run,
Jump,
Skip
}
And your method
private void SomeMethod(UsrActions usrAction)
{
switch(usrAction)
{
case UsrActions.Jump:...
case UsrActions.Walk:...
...
}
}
Then when using the method if you're in Visual Studio you get to this point
someObject.SomeMethod(
Intellisense will pop-up with letting you know its expecting a type UsrAction, just type UsrAction. and up pops the list of UsrAction s to choose from.

I have created a simple client/server remoting interface that basically allows the client to get a byte array from the server. I am wanting to develop something that will allow the main thread on the server to initialize a byte array and allow the client to access this byte array from the interface. Does anyone have experience doing such a thing? Below is an example of what I want to do; but, don't know how to make it work. Look for initialization and How do I do this within the code comments.
using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using RemoteInterfacecls; //Code not proviced at this time
using System.Runtime.Serialization;
namespace RemotingInterfaceServer
{
public class dataStuff
{
public byte [] mystuff;
}
public class EntryPoint
{
public static void Main(string[] args)
{
dataStuff dS = new dataStuff();
//Here is the initializaton
ds.mystuff = System.Text.Encoding.ASCII.GetBytes("This is a test");
TcpServerChannel channel = new TcpServerChannel(2566);
ChannelServices.RegisterChannel(channel);
RemotingConfiguration.RegisterWellKnownServiceType(
typeof(RemoteExample),
"RemoteExample", WellKnownObjectMode.SingleCall);
System.Console.WriteLine("Hit Key to Exit");
System.Console.ReadLine();
}
}
public class RemoteExample : MarshalByRefObject, IRemoteExample
{
public RemotingExample()
{
Console.WriteLine("Constructor Called ");
}
public IByteArray GetByteArray()
{
ByteArray byteArray;
//This is the from the main initialization
// How do I do this ???????????
byteArray.bytesRead = mystuff;
return (IByteArray)byteArray;
}
}
[Serializable]
public class ByteArray : MarshalByRefObject, IByteArray
{
public byte [] bytesRead;
}

After many hours of banging my head, I finally realized that the interface should of belonged to the class Entry point. Once I did this, I was able to do what I wanted. Here is a tidbit of the code I used.
using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using RemoteInterfacecls; //Code not proviced at this time
using System.Runtime.Serialization;
namespace RemotingInterfaceServer
{
public class dataStuff
{
public byte [] mystuff;
}
public class EntryPoint
{
dataStuff dS = new dataStuff();
public static void Main(string[] args)
{
//Here is the initializaton
ds.mystuff = System.Text.Encoding.ASCII.GetBytes("This is a test");
TcpServerChannel channel = new TcpServerChannel(2566);
ChannelServices.RegisterChannel(channel);
RemotingConfiguration.RegisterWellKnownServiceType(
typeof(RemoteExample),
"RemoteExample", WellKnownObjectMode.SingleCall);
System.Console.WriteLine("Hit Key to Exit");
System.Console.ReadLine();
}
public class RemoteExample : MarshalByRefObject, IRemoteExample
{
public RemotingExample()
{
Console.WriteLine("Constructor Called ");
}
public IByteArray GetByteArray()
{
ByteArray byteArray;
byteArray.bytesRead = dS.mystuff;
return (IByteArray)byteArray;
}
}
[Serializable]
public class ByteArray : MarshalByRefObject, IByteArray
{
public byte [] bytesRead;
}
}
}

Hello everyone , I'm in the process of writing a webservice for a small application im making, I lack a database so what im doing it making a folder on the server for each person that registers. I have a serperate folder in which when I am done will contain a text file for each member containing their password. I have completed the part of the webservice that creates a folder with the name they enter but when I went to make the part that makes the text file for their password I get an error: "Cannot create an instance of the abstract class or interface 'System.IO.TextWriter'. For the life of me I cannot figure what is wrong. Can anyone give me a hand in finding the error? I figure it is a very obvious mistake, heres my method:
[WebMethod]
public void RegisterAccount(string Name, string Password)
{
string path = @"G:\ArtAccounts\"+Name;
System.IO.Directory.CreateDirectory(path);
TextWriter PassWriter = new TextWriter(@"G:\ArtAccountsPasswords\"+@"Name.txt");
PassWriter.WriteLine(Password);
PassWriter.Close();
}
|
|
|
|
|
TextWriter is an abstract base class use StreamWriter
[WebMethod]
public void RegisterAccount(string Name, string Password)
{
string path = @"G:\ArtAccounts\"+Name;
System.IO.Directory.CreateDirectory(path);
StreamWriter PassWriter = new StreamWriter(@"G:\ArtAccountsPasswords\"+@"Name.txt");
PassWriter.WriteLine(Password);
PassWriter.Close();
}
