Re: User control not updating when running project

A bit harsh, but this should do the trick;

Right-click on the toolbox, and choose "Reset Toolbox".
Right-click on the toolbox, and choose "Choose Items.."
Select "browse" to navigate to the assembly containing the UserControl.

Closing Visual Studio and losing your changes without a prompt is really strange. I think Visual Studio is corrupt.

Does it update if you close the user control and main window, then build and reopen the main window?

If so go with that.

That seems to be working thanks. Although I'm not sure if the Easter Break has done my PC some good.

I'll make sure everything is update to. Hopefully my 2010 installation is causing any troubles.

User Shared File Access

I’m using Visual Studio 2010 on Windows 7

I’m trying to write a log file in one program while reading the same log file in a second program.

The first program receives data from a server every minute from second 0 through second 5.

I want the second program to sleep till 30 seconds after each minute, read the traces from the first program’s log file, and display any warnings.

I found a post on the web saying I should open the file in program 1 as:

_logStream = new FileStream(logFileName, FileMode.Create, FileAccess.ReadWrite, FileShare.Read);
_logFile = new StreamWriter(_logStream);

Then open the file in program 2 as:

var _logStream = new FileStream(filename1, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
var xyz = new StreamReader(_logStream);

But I get the error message:

Unhandled Exception: System.IO.IOException: The process cannot access the file '
C:\SandBox\120405133716.log' because it is being used by another process.

Can this be done in Window's 7 ??
If so, what is the proper code ??

I don't like textfiles as a buffer. I'd switch to a database, and do insert's and selects - that would also solve the problem of simultaneous access.

No. The only code you're going to get is the code you write.

Is that supposed to mean something?

1. Press the windows key + R.
2. In the dialog that appeared, type in the code "notepad" (without quotes)

Notepad launches.

Notepad is basically a TextBox. Create a form, add a TextBox and menu items to load/save text, and you essentially have NotePad.

Hi I have application that is define as MDI,
there are several form child
once the user press X button, i wish the application to be close and all other windows.
at the FromClosing event i add the following code
//handle and close the logic layer...
foreach (Form frm in this.MdiChildren)
{
frm.Close();
frm.Dispose();
}
Application.Exit();
All childs are closed but the the event FromClosing
happen agian, why?
i would expect the event of the main form FromClosing will happen only one time.
this cause my problems at the logic layer

Because you called "Application.Exit", which will close all the forms and exit the application. You needn't close all forms manually, exiting the application should be enough and should close all remaining forms (and dispose them) automagically.

There are TWO X-es on a MDI-form if you have the children maximized. If you want to close the application, you close the mainform. That's how things work in Windows, and across all other MDI-applications. If you close one of the child-windows by using it's X, then you are merely closing that particular document of the "Multiple Document Interface".

Likewise, Ctrl-F4 would close a child-document, Alt-F4 would close the application.

Ronenb wrote:

Application.Exit from code, the X topright of the mainform or Alt-F4 from user-input.

Yes. Post the code from the children's OnCloseForm handler.

Start a new project, add this code;

namespace WindowsFormsApplication15
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            this.IsMdiContainer = true;

            new Form() { MdiParent = this, Visible = true };
            new Form() { MdiParent = this, Visible = true };
        }
    }
}

That'll display two documents within a MDI-parent. App will close on X, unless you have some custom code somewhere.
