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;
}
}

why is there a 13 and must i use it in my program too?
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?

first the user keys in something in the textbox and then he press enter on the keyboard.. after enter key is pressed, i want to move to tabPage6..
this is what i did:
private void button3_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
if(e.KeyChar==(char)13)
{
this.GetNextControl(button3,true).Focus();
tabControl1.Focus();
tabControl1.SelectedTab=tabPage6;
e.Handled=true;
}
}
but when i run the app and i press enter, tabPage6 is not displayed.. only when i click on the button it will be displayed..
thanks again for your kind attention! =)

Of Course !
because you but the code that move the focus in command button3 keypress event handler
nidhelp wrote:
private void button3_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs
so to make this happen when key pressed in textbox you must handle keypress event so you have two choice
after subscribe to textbox keypress event like you did in commandButton pass button3_KeyPress to it like the following
this.textBox1.KeyPress += new stem.Windows.Forms.KeyPressEventHandler(this.button3_KeyPress);
or create new function and copy the code in command button
keypress event in it so the subscip line will be like this
this.textBox1.KeyPress += new System.Windows.Forms.KeyPressEventHandler(this.textBox1_KeyPress);
Note:1-you dont have to write this code visual studio
will write it for you all you will do that you select to use existing function or new one
2-in your case you dont need this line of code
this.GetNextControl(button3,true).Focus();
Remove it or comment it by write // before them
