there is no explicit\implicit way on converting char[] to string, and overriding will cause a-lot of problems. just use this function (you can change and it's better to change the static in it):

static private string CtoS(char[] charArr)
{
    string tmp = "";
    for (int i = 0; i < charArr.Length; i++)
        tmp = tmp + charArr[i];
    return tmp;
}

a question about notifyicon ?

12-May-06 2:02

I have a textarea for which when the text exceeds the length of the textarea the text should come down to the next line without any horizontal scroll bars appearing. This is the default behaviour in IE but in Firefox whenever the text exceeds the length of the textarea, horizontal scrollbars appear (which i do not appear).Please advise.

hi all,
i added the following code into mouseclick event :
private void notifyIcon1_MouseClick(object sender, MouseEventArgs e)
{
if ((e.Button == MouseButtons.Left) || (e.Button == MouseButtons.Right))
notifyIcon1.ContextMenuStrip.Show();
}
>for right click there is no problem. everything works fine, i only see the contextmenustrip.
> but as for left click; apart from the contextmenustrip, the application's icon shown on 'Taskbar' and this is not something good Wink | ;)

what should i do in order not to let the icon shown on TASKBAR for single left click on notifyicon ?
thanks in advance,
bye.

as i seen... you use the show commmand (I think I told you how to do this, it looks like my code)
but you don't supply a point for it, so it just opens where it thinks to open... in the show method just write the mouse point:
this.notifyIcon1.ContextMenuStrip.Show(MousePosition);
this will be alot easyer than using notify icon contextmenustrip show cmd without pointing on the point...

I think he is not asking the ContextMenuStrip position, he is asking about when u right click, it creat another icon on the taskbar along with form icon..

is it correct?

implementing form closing event ? help please ...

hi all,
i want to implement form_resize and/or form_closing event. i added these two lines in form1.designer.cs:

this.Form1_FormClosing += new System.Windows.Forms.FormClosingEventArgs(this.notifyIcon1_MouseDoubleClick);
this.Form1_Resize += new System.EventArgs(this.Form1_Resize);

and add some appropriate code in Form1.cs but when building the solution i get the following errors:
>Error 1 No overload for method 'FormClosingEventArgs' takes '1' arguments
>Error 2 No overload for method 'EventArgs' takes '1' arguments
how can i fix these problems ?

ps: codes in Form1.cs are :
private void Form1_Resize(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized)
this.Hide();
}

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
if (e.CloseReason == CloseReason.UserClosing)
{
e.Cancel = true;
this.WindowState = FormWindowState.Minimized;
}
}

Re: implementing form closing event ? help please ...

No it should be like this

this.Resize += new System.EventHandler(this.Form1_Resize);<br />
this.FormClosing += new System.Windows.Forms.FormClosingEventHandler(this.Form1_FormClosing);

Why did u add these codes manually, instead go to the Form1's properties window and click the events button, then double click the event u want to write.

Hope this is wat u want.

Thanks,
Srini

This is really annoying me, I'm sure there is a simple method but I just cant find it anywhere.

I have an 'options' form that I show when the user wants to change options, but how do I read variables from the mainform in the options form, and then change them when the user clicks ok on the options form? I have tried making the variables public with no success.

Hope someone can quickly put me out of my misery Smile | :)

Read This[^]

and try working something like this...
when you'll make the variables public and send the last form as the last form (not as type Form), then you can access them through
VarForm.Var;...

good luck

No no and no!

In MVC pattern Views do not know about each other! Forms are Views. Coupling forms is a violation of fundamental design principles.
