You're using the wrong overload of the Add method. Passing a string as the frst parameter causes a new MenuItem to be created for you, with the supplied text as the caption and the specified handler. You need to specify the handler in your PJMenuItem constructor (and pass it to the base class constructor) then used the version of the Add method that takes a reference to the menuitem.

g'day Rob
Would it be possible for you to give me another example of your explanation as I am unable to follow through. The point I am having difficulty is with the part where you said i need to specify the event handler in the constructor and then passing it to the base class constructor.
I am refering to the following article on msdn about base class constructors:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/csref/html/vclrfbasepg.asp
But I cant seem to draw a correlation between the msdn article and your explanation.
I would really appreciate it if you could give me another example.
thanks.

okay, here it is. i have this
as my opengl window, on load, and this image i need to draw fullscreen. basically the code looks like this:
this.ClientSize = new System.Drawing.Size(640, 480);,
GL.glVertex3f(0f,0f,0f);
GL.glVertex3f(640f,0f,0f);
GL.glVertex3f(640f,480f,0f);
GL.glVertex3f(0f,480f,0f);, and
GL.glOrtho(0,640,0,480,0,1);. as previously stated, i want the image to be drawn in the exact amount of pixels that it came with. in case pointers arent enough and a whole source fix is needed, the source for tyhe entire program can be found here. thanks for your time

Rob,
EXACTLY what my App needed.Didn't even know there was such a thing as
"current culture". Many thanks.....
|
|
|
|

If you ever intend to write applications that might be used outside your country, you should read up on the CultureInfo[^]and System.Globalization [^] Name space. Most of the string formatting and comparison functions in .NET have overloads that expect culture specific parameters, and it is generally recommended that you use these to get predicatable results in all languages.

Hi!
Im using an arraylist bound to a datagrid to show some info. I also let the user delete rows from the datagrid using a contextmenu. IE rightclick on the row, choose "delete item", and the row disappears.
Everything works fine except when I delete the last row, then when I choose another row I get a "Index out of range exception".
this is my deletemethod:
private void DeleteItem(object sender, System.EventArgs e)
{
//get the index of the selected Item, same index in the ArrayList
int index = commentGrid.CurrentCell.RowNumber;
try
{
comments.Comments.RemoveAt(index);
if (comments.Comments.Count < 1)
{
menuItemExport.Enabled = false;
toolBar.Buttons[2].Enabled = false;
}
dataChanged = true;
commentGrid.DataSource = null;
commentGrid.Refresh();
commentGrid.DataSource = comments.Comments;
commentGrid.Refresh();
}
catch(ArgumentOutOfRangeException)
{
return;
}
}
I heard this was some kind of bug in .NET, but I dont know how to work around the problem! Any help is much appreciated.
thanks!

You can achive what you want by handle keypress event
Catch enter key
Set The Focus to the next control
Try some thing like this
<code>
private void Text_KeyPress
(object sender,System.Windows.Forms.KeyPressEventArgs e)
{
if(e.KeyChar==(char)13)
{
this.GetNextControl(textBox1,true).Focus();
e.Handled=true;
}
}
</code>

13 is the numeric value of the character sent by the enter key.

you can modify the code above to do what you want
the code did not work because -i think- the tabcontrol not the next control to textbox i mean if textbox tabindex=7 the tabcontrol should be 8
you can do somthing like that
private void Text_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
if(e.KeyChar==(char)13)
{
tabControl1.Focus();
tabControl1.SelectedTab=tabPage2;
e.Handled=true;
}
}

as rob said this the value of enterkey as this numric value and KeyChar type is Char so we need to cast it
in other word convert numric value to char
one of the method to do that is
(char)13 which wil do the conversion
if you want to know the value of other key
look at
Keys Enumeration[^]

i tried modifying again but it still cant work.. i want to ask..
private void Text_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e) << do i write Text_KeyPress too? or should i replace Text with something else?
{
if(e.KeyChar==(char)13)
{ //this.GetNextControl(textBox1,true).Focus(); >> do i remove the //?
tabControl1.Focus(); tabControl1.SelectedTab=tabPage2; e.Handled=true;
}
}
as for tabControl1, textBox1 and tabPage2 in the above codes, do i write the relevant names of my tabcontrol, textbox and tabpage of what i want to link to/from?
thanks!

If you take this code Copy and Paste of course it will Not work you need to modify it
1-Text_KeyPress this function will be called when KeyPress event fire in textbox so change its name to your Function name or copy the body of the function to yours
2-The Control names tabControl1,tabPage2 and textBox1
you need to change this name to yours

i have modified the codes but it still cant work.. can anyone see what's wrong with it?
private void button3_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
if(e.KeyChar==(char)13)
{
this.GetNextControl(textBox4,true).Focus();
tabControl1.Focus();
tabControl1.SelectedTab=tabPage6;
e.Handled=true;
}
}

Can you explain again what you really want exactlly
Are you want to move to the tab control after you press Enter on button OR text control
The code you write do the folowing
If buuton control key press event fired
Set the focus to the control next to textBox4
And move focus to tabpage and select the page
So what you get when you run the code?
