I installed connector.net but still occered this error.
my connection string is:
connectionstring = "Provider=MySQLProv;Data Source=test;User Id=root;Password=Password;";
what i do plz help me...

Your connectionstring is based on the OleDb format, which you can also use to connect to MySQL. I guess that you'll either need a different connectionstring (for Connector/NET) or use a different provider (like OleDb).
Try the connectionstrings mentioned here[^].

Hey everyone,
I've been developing this database application for the last two years and now my boss wants me to translate it to other languages, I have some rough ideas about how that could be done but I dont believe any of them are official so here's my question:
What is the best practice in changing your application language?? "You know, the text properties of all the controls of your interface", any official way to do that?? Other than looping over the controls and reading the corresponding word from a text file or a csv file which I think would be a lame practice??
Please advise guys.
Many thanks!

Yep that's the one  , then a copy of each label for each language in the database. That's what we did, worked perfectly, we had a separate DB set up for the language tables as they are unicode and the main DB only used varchar.
The language DB then got played with by various divisions to add and improve the label translations. Last I heard there were 6 languages supported, 2 of which were Chinese dialects.

Hey Holmes,
Hmmmm, sometimes I hate using our logic when there could be more proper ways to perform casual tasks like this one but I think you're right, it's not that bad after all. But I'll go for the CSV file instead so I can make sure the user gets the language version without touching the database, besides, it is considered a part of the interface package not the database.
Thank you for sharing Holmes!

It's Sunday - give it a few hours and see if the states come up with some more productive ideas, what you are doing is not new, I'm confident there are a number of solutions out there.

Hi everybody,
I'm developing a windows based app. We are still in developing phase, so there are a lot of changes which should be sent to users every day. I need a suitable publishing method and found ClickOnce a good solution for our regular updates. But, there are some problems:
1) The app is multilayer with couple of projects. each project has some config and some user defined meta data files which should be with exe file. How can I add them to ClickOnce? just the config file of the exe project is added!!!!
2) there are some projects which are loaded by reflection in app. So there is no direct dependency between them and exe project, how can I add them too?
Thanks,
|

Presumably you have the configs stored in a file somewhere, add the file(s) to the project. We store user configs in their app data folder but that is for stuff created by the app and is not downloaded.
As for 2, get rid of reflections - this is a design issue. OR add a dependency to the assembly, this probably has the same affect as referencing the project anyway so there is probably limited value in using reflections for late binding.

I'm a beginner to Microsoft Visual C# 2008 Express Edition. I get the following error...
The server committed a protocol violation. Section=ResponseHeader Detail=CR must be followed by LF
When trying to use a solution posted here: http://forums.cpanel.net/showpost.php?p=468581&postcount=2
I've googled for this yet none of the solutions make any sense to me.
Any help is greatly appreciated since I'm fairly stumped on this one. If you need more info just ask!

I Googled for 'The server committed a protocol violation' and got a shed load of hits.
The consensus seemed to be that you need <httpWebRequest useUnsafeHeaderParsing="true" /> in your config file.
However I would suggest that you Google for yourself to see if any of the circumstances fit your situation exactly.
Good luck!

Thanks! I was wondering through, in Visual C# Express, where do I need to put that? I've heard about app.config and web.config but I don't know where they're located.
|

Normally you don't have to 'put' app.config or web.config files anywhere, that is all taken care of for you by the IDE.
I can only suggest that you take a look at this[^] page from MSDN about web.config.

Have you tried this?[^] It seems to be a suggestion to the same question that you asked a few hours ago. Did you follow up that suggestion? If you did, what was the outcome? If not, why not?

I'm fairly new to C#, and have written a small app to test something I needed to do in a bigger app. The app is simple, has a single main form and the routine creates a task bar icon. The only event that is serviced is when the user doble-clicks on the icon in the tray. Double clicking will hide the main window, double clicking again will show the main window. All that I understand, but he mapping of the ShowWindow functions has me seriously confused. I kind of understand the mapping of the ShowWindow function, but the Handle argument with the call makes no sense. Handle isn't declared anywhere, isn't intialized and yet the thing works. I've included thye code below:
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
namespace Foo_Bar
{
///
/// Summary description for Form1.
///
public class Form1 : System.Windows.Forms.Form
{
private System.ComponentModel.IContainer components;
public Form1()
{
//
// Required for Windows Form Designer support
//
InitializeComponent();
}
///
/// Clean up any resources being used.
///
protected override void Dispose( bool disposing )
{
if( disposing )
{
if (components != null)
{
components.Dispose();
}
}
base.Dispose( disposing );
}
#region Windows Form Designer generated code
///
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
///
private void InitializeComponent()
{
this.components = new System.ComponentModel.Container();
System.Resources.ResourceManager resources = new System.Resources.ResourceManager(typeof(Form1));
this.notifyIcon1 = new System.Windows.Forms.NotifyIcon(this.components);
//
// notifyIcon1
//
this.notifyIcon1.Icon = ((System.Drawing.Icon)(resources.GetObject("notifyIcon1.Icon")));
this.notifyIcon1.Text = "notifyIcon1";
this.notifyIcon1.Visible = true;
this.notifyIcon1.DoubleClick += new System.EventHandler(this.notifyIcon1_DoubleClick);
//
// Form1
//
this.AutoScaleBaseSize = new System.Drawing.Size(5, 13);
this.ClientSize = new System.Drawing.Size(192, 110);
this.Name = "Form1";
this.Text = "Form1";
}
#endregion
///
/// The main entry point for the application.
///

{
Application.Run(new Form1());
}
private System.Windows.Forms.NotifyIcon notifyIcon1;

private const int SW_RESTORE = 1;
private static bool VisibleBoolean = true;

private void notifyIcon1_DoubleClick(object sender, System.EventArgs e)
{
if (VisibleBoolean)
{
ShowWindow(Handle, SW_HIDE);
VisibleBoolean = false;
}
else
{
ShowWindow(Handle, SW_RESTORE);
VisibleBoolean = true;
}
}
}
}

Handle is declared (without your knowledge). It's a property of this (the Form).
/ravi
|
|
|
|
|
Handle is inherited from the Form class (which inherits it from the Control class). It's initialized during the construction of the Form1 object.
Congrats on being new and understanding how to use DllImport to call native functions, but there's an easier way that doesn't involve any of that. The Form class also has Hide() and Show() methods that accomplish the same thing as calling ShowWindow(...), and it has a Visible property that is the same thing as your VisibleBoolean.
I suggest that you either read the docs on the Form[^] class or use the Visual Studio intellisense to see what functionality already exists.

Yep, found them... Sorry, did an internet search for hiding main window and got a lot of "It's tough" Didn't think about a hide or show method for the form. One last question... why do you (not you personnaly) not have to (or can't) include the form name when using the hide or show methods? Like this.Form1.Hide (), or this.Form1.Visdible. Beyond the obvious it seems to me that would at least be optional. I know, beginner question...

Form1 is the type of the object, "Form1" is the value of the Name property of the object. The Name is just a place to store a user friendly and unique identifier for an object. The programmer friendly identifier is the variable name, in this case it's this.
I'm not sure what value there would be in being able to write this.Form1.Hide(), the compiler already knows the type of the this object, and programmer must be aware of it to be using it's members.

"Form1" is the class name. "this" refers to a specific instance of that class, an actual object.
You must use the class name when referring to static variables of that form, and you must (or can) use the instance reference when referring to instance variables.
Trying to precede the class name with the instance reference (this.Form1) is not really meaningful, and more than a bit confusing.
The "this" keyword is optional mainly because people get tired of typing it, I think. But there are cases where it must be used. When you have a class-scope variable and a method local variable with the same name, the "this" keyword specifies the class-scope variable. Otherwise, the local-scope variable is used.
Codemonkeys don't do it at all. Too busy coding.

hello

class B1, B2, B3 are derived class from B0
i show my object A in a propertygrid and i want to select ( create instance) for property People with instance B1, B2 or B3
how can i do that with TypeConverter or something else
i already know make it with collection ( using an derived collection editor)
but for objects in property grid i do not
can somebody help me
