With MDI I'm not sure, but have you tried changing the child form's StartPosition property to Manual?

Try code model generation tools at BoneSoft.com.

Thanks! That did the trick. I thought I had tried that already, but I've done so many different things trying to make this work, that perhaps it was a different version of the form, or a different drawing mechanism. Regardless, it works like a champ now. Thanks again!

That is ASP.NET and don't tell them "it did not work" you need to be specific.

following is my simple code which accept the request from client site, then reponse.

<br />
int port = 8080;<br />
			// Create server socket <br />
			Socket proxyServer = new Socket(AddressFamily.InterNetwork,<br />
				SocketType.Stream,ProtocolType.Tcp); 				<br />
			proxyServer.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.SendTimeout, 5000);		    <br />
			<br />
			// call the Listen method to listen for and queue incoming connection requests.			<br />
			proxyServer.Bind( new IPEndPoint(GetHostIP(), port) );<br />
			proxyServer.Listen( port );<br />
<br />
			// Display start message <br />
			Console.WriteLine("ProxyServer started at port " + port);<br />
			Console.WriteLine("ProxyServer ready for accepting incoming connections...");	<br />
<br />
			//endless loop<br />
			while(true)<br />
			{<br />
				// waiting for client <br />
				Socket clientConnect = proxyServer.Accept();		<br />
				// Create the NetworkStream for communicating with the remote host.<br />
				NetworkStream clientStream = new NetworkStream( clientConnect, true );	<br />
<br />
				HttpWebRequest loHttp =	(HttpWebRequest) WebRequest.Create("http://www.google.co.uk/intl/en_uk/images/logo.gif");<br />
				// Set properties - 10 secs<br />
				loHttp.Timeout = 10000;  <br />
				// Retrieve request info headers<br />
				HttpWebResponse loWebResponse = (HttpWebResponse) loHttp.GetResponse();	<br />
<br />
				System.IO.StreamReader loResponseStream =<br />
					new System.IO.StreamReader(loWebResponse.GetResponseStream()<br />
					, System.Text.Encoding.UTF8);<br />

				//Console.WriteLine(lcHtml);<br />
<br />
				loWebResponse.Close();<br />
				loResponseStream.Close();<br />
<br />
<br />

Hi mike,

Thanks for your reply,but i am not quite clear about what you said, do you mean i should save my code part in GIF format file then upload it? GIF? a picture? Confused | :confused:

The part that uses a HttpWebRequest to download the image file resulting in a byte array containing the image. That should be isolated and unit tested. The unit test could save the byte array to a disk file that can be verified to be correct. None of that has anything to do with your "proxyServer" and sending the byte array to the client socket. That is why it can and should be "isolated". Take some time to read about software design principles.

Hi all. I need to call a method of my .NET COM-object from Word. How can I do it?
I've written an object, checked all these "COMVisible", "register for COM Interop" etc.
In Word I can see a reference to it. After adding the reference I write the script:

Dim Ob As Object
Set Ob = CreateObject("ClassLibrary1.FOO")

On CreateObject line I get: "Run time error 429. ActiveX component can't create object".

Or if I write so:

Dim Ob As Object
Set Ob = New Classlibrary1.FOO

I get: "Run-time error -2147024894 (80070002). File or assembly Classlibrary1, or one of it's dependencies was not found".

Which dependencies? It's just a test project! Here is the source code:

using System;
using System.Runtime.InteropServices;

namespace Chapter_Code
{
[GuidAttribute("1C6CD700-A37B-4295-9CC9-D7392FDD425D")]
public interface IFoo
{
string PrintMe();
int ShowState();
void SetState(int newState);
}

[GuidAttribute("C09E2DD6-03EE-4fef-BB84-05D3422DD3D9")]
[ClassInterfaceAttribute(ClassInterfaceType.AutoDispatch)]
[ProgIdAttribute("Chapter_Code.Foo")]
public class Foo : IFoo
{
public Foo() { }
private int state = 100;

public string PrintMe()
{
return ("TEST SUCCESS");
}

public int ShowState()
{
return (state);
}

public void SetState(int newState)
{
state = newState;
}
}
}

Your help is much appreciated!

it's .NET COM object, so I used "regasm CodeLibrary1.dll /codebase".
There were some little mistakes in namespace and ProgID in my code. So here is the final variant:

using System;
using System.Runtime.InteropServices;

namespace ClassLibrary1
{
[GuidAttribute("1C6CD700-A37B-4295-9CC9-D7392FDD425D"),
InterfaceType(ComInterfaceType.InterfaceIsDual)]
public interface IFoo
{
[DispId(1)]
string PrintMe();
[DispId(2)]
int ShowState();
[DispId(3)]
void SetState(int newState);
}

[GuidAttribute("C09E2DD6-03EE-4fef-BB84-05D3422DD3D9"),
ClassInterfaceAttribute(ClassInterfaceType.None)]
[ProgIdAttribute("ClassLibrary1.Foo")]
public class Foo : IFoo
{
public Foo() { }
private int state = 100;

public string PrintMe()
{
return ("TEST SUCCESS");
}

public int ShowState()
{
return (state);
}

public void SetState(int newState)
{
state = newState;
}
}
}

Now using CreateObject or New gets the same error: "Run-time error -2147024894 (80070002). File or assembly Classlibrary1, or one of it's dependencies was not found".

The following function will format a datetime like the old vb dateformat and return a varchar. I use this all the time to format dates in my applications.

/****** Object: UserDefinedFunction [dbo].[udf_FormatDate] Script Date: 07/05/2006 11:11:54 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

create FUNCTION [dbo].[udf_FormatDate] (@date datetime, @format varchar(50))
RETURNS VARCHAR(50) AS

-------------------------------------------------------------------------------------
--
-- Name: FormatDate
--
-- Purpose: Mimics the VB Format routine for dates
--
-- Parameters:
-- @date - Date, Date to be formatted
-- @format - String, Template to format the date to
--
-- Returns: String, Date formatted to user requested template
--
-- Notes:
-- 1. Time information is not accounted for in this routine
--
-- 2. @format accepts the following values for each section of the date.
-- Day
-- dddd - Full Day Name
-- ddd - Abbreviated Day Name
-- dd - Zero Padded Day Number
-- d - Day Number
--
-- Month
-- mmmm - Full Month Name
-- mmm - Abbreviated Month Name
-- mm - Zero Padded Month Number
-- m - Month Number
--
-- Year
-- yyyy - Full 4 digit year
-- yy - 2 digit year
--
-- 3. Any unexpected characters will be returned in the string
--
-- 4. Assumes database was set up with case-insensitive collation
--
-- Example Usage:
-- All examples use the following date 2003-07-13 00:00:00
--
-- 'dddd, mmmm dd, yyyy' --> Sunday, July 13, 2003
-- 'mmddyyyy' --> 07132003

I don't understand your problem. Perhaps if you posted your code it might help.

DateTime theDate = new DateTime(2006,07,05, 17, 11, 00);
SqlCommand cmd = new SqlCommand();
cmd.Connection = someConnection;
cmd.CommandText = "SELECT * FROM MyTable WHERE dateColumn = @dateValue";
cmd.Parameters.Add("@dateValue", theDate);
SqlDataReader reader = cmd.ExecuteReader();
// etc.

As you can see there is no need to format the date at all.

Shadow copying is a feature of the ASP.NET runtime. It is not used in WinForms because the WinForms compilation model is not dynamic.

Not Active

5-Jul-06 7:49

WinForms does use ShadowCopy. Actually, the .NET framework itself uses this method also. When an assembly is loaded from the GAC it is really using a shadowcopy, this allows assemblies in the GAC to be updated without the risk of being locked by an application.

Using the AppDomainSetup object you can set the path and whether or not to use shadowcopy when creating a new AppDomain. I have used this method to load assemblies for use in an application and allow them to be updated while the app is running. If the assembly is updated the AppDomain is unloaded and created again there by getting the newer version for use while the app remains active for the user.
