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
BEGIN
-------------------------------------------------------------------------------------
--
-- 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
-- 'm-d-yy' --> 7-13-03
-- 'mm/dd/yyyy' --> 07/13/2003

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.

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.

C# Cross-Class function calls

czell5-Jul-06 3:57

5-Jul-06 3:57

I have a Windows Form (Form1 is class name) which is the GUI for my app. In Form1 class I have some methods for writing to a textbox. In the same namespace I have another class from which I would like to call Form1's method for writing to that textbox.

Question: How can I call Form1's methods from the another class. I understand how to make calls across classes using instances, but how can I do this when I dont have an instance of Form1 in the other classes? I've tried using static modifiers to Form1's textbox function but that brings up other problems.

So how can I access the Form1's members and methods from another class??

Thanks

You'd have to find a way to get a reference to the running form. Don't know how you would accomplish that unless the form is instantiating the class in question.

However, what you described sounds like a design choice you should probably reconsider. Instead of having a class that alters a text field, you might want to have that class just take some input and return a string so that any form with a text box can use that functionality.

First, although there are other alternatives, in your case it's better for other classes to call Form1 object. Static methods are not a good option here, as you may want to handle multiple Form1 instances.

Second, Form1's data members aren't supposed to be accessed/altered directly by other classes. A better design would be adding Property to Form1. Outsiders access Form1 properties and Form1 binds these properties with its own controls.

Best,
Jun

Hello!

When I try to execute a program sometimes it doesn´t work, and if I stop the debug the program that I wanted to be executed initializes =/. It really annoys me!!
What is happening?

Process.Start(ProgrammePfad, AuftragsVerzeichnis);

or

Process p = new Process();<br />
            ProcessStartInfo startInfo = new ProcessStartInfo();<br />
            startInfo.FileName = ProgrammePfad; // Programm Path<br />
            startInfo.Arguments = AuftragsVerzeichnis; // Programm Arguments<br />
            startInfo.ErrorDialog = true;<br />
            startInfo.WindowStyle = ProcessWindowStyle.Normal;<br />
            <br />
            <br />
            p.StartInfo = startInfo;<br />
            p.Start();

Both of them sometimes work, sometimes don´t! =/
The program that I want to be executed is called InTouch WindowMaker.
Thanks!

Are you trying to communicate with the program that you try to execute? If not, what exactly does "it doesn't work" mean?

You could try calling WaitForInputIdle[^] right after starting the process and see if it helps.

Seeking Input value from Dialog box but not closing it

For_IT5-Jul-06 3:20

For_IT

5-Jul-06 3:20

Hi I am creasting an application where I am implementing "search and replace word" functionality. I have a dialog "SearchAndReplace" which takes two text inputs and has three buttons as "FindNext", "Replace" and "Close"

I have implemented following code in my main form:

My main class code is:

<br />
if (SearchReplaceDialog.ShowDialog() == DialogResult.OK)<br />
{<br />
     if (SearchReplaceDialog.WithReplace)<br />
     {<br />
	int c = this.Editor.Replace(SearchReplaceDialog.Search, SearchReplaceDialog.Replace, SearchReplaceDialog.Match, SearchReplaceDialog.Word, SearchReplaceDialog.Up);<br />
	MessageBox.Show(c.ToString() + " strings found and replaced");<br />
     } <br />
     else <br />
     {<br />
	bool r = this.htmlEditor1.Find(SearchReplaceDialog.Search, SearchReplaceDialog.Match, SearchReplaceDialog.Word, SearchReplaceDialog.Up);<br />
	if (!r)<br />
	{<br />
	 MessageBox.Show("String '"+SearchReplaceDialog.Search+"' not found");<br />
	}<br />
     }<br />
}<br />

SearchDialog code:

<br />
private void btnFindNext_Click(object sender, System.EventArgs e)<br />
{<br />
     Match = this.chbMatchCase.Checked;<br />
     Word = this.chbMatchWholeWord.Checked;<br />
	Up = this.chbSearchUpward.Checked;<br />
	Search = this.txtFindWhat.Text;<br />
	Replace = this.txtReplaceWith.Text = String.Empty;<br />
	WithReplace = false;<br />
<br />
	DialogResult = DialogResult.OK;<br />
}<br />

When I click Find Next, the Search and replace dialog box closes. I want to retain it on top of application and close the dialog when user closes it on Clicking "Close" button.

Can anyone please suggest my how can I achieve this?

Thanks

As stancrm me eluded, setting DialogResult to DialogResult.OK is what's closing the form. As he suggested, you can set it to DialogResult.None, or don't set it at all on Find Next.

Your question gave the impression that you also need help getting information from the dialog form. You could have it publish events to notify the using form of the information in a match on Find Next, which would help you accomplish that.

I would like to ask user name and password when accessing to database with login prompt but seems that there doesn't exist the same mechanisn than eg. earlier VB connection object. (like connection.Properties("PROMPT") = adPromptComplete)
This kind of login form would be useful especially in situation when I get default connectionstring with Integrated Security=SSPI and that doesn't work...
C# connection object doesn't have properties property??
