The negation operator (!) has a higher precedence than the logical or operator. I think you made a typo yourself when you went from steps:
if(! (false && true) || (true && true))
To:
if( ! (false || true) )
Personally, I would suggest just using the debugger and putting a watch in to see what exactly is going in. Put the full statement "(!(intPosHomeUS > 0 && intPosHomeUK > 0) || (intPosHostUK > 0 && intPosHostUS > 0))" and then break it down into pieces to find the error.
As a side note, I'm not a big fan of putting a negation like that because it always seems to trip me up (may just be me). So, I typically pass the negation through the set...so you'd have something like this instead:
if (intPosHomeUS <= 0 || intPosHomeUK <= 0 || (intPosHostUK > 0 && intPosHostUS > 0))
It's just DeMorgan's Law...you can find more about it here[^].

It tends to trip me up as well, but I prefer writing the exression in the intuitive 'as english' format and either using a temp var for the base expression and then notting the temp in the expression or switching the then and else clauses around to avoid the negation all together.

Yes, it should, and it does.

Is this a logic issue? I noticed that you're not checking for a value from intPosHostUK

Hi,
I need to know how can I create shotcut to myButton on form when I press key F10 independent of current active control on form, without using "ShortcutKey" in "ToolStipMenuItem".
I can do this if myButton is active control on form. I explicitly need to use key F10, so I can't use an & (ampersand) in a button text.
Thanks for help

handle key down or key up event of the form and then trigger click event by;
if(e.KeyCode == Keys.F10)
button1.PerformClick();
hope it helps.

Hello,
And dont't forget to set:
this.KeyPreview = true;
All the best,

Thanks both, it really works.

Hi,
I have just one more question. Can I check if ALT+F1 pressed?
Thanks,
Jure
|
|

|

Hello,
Yes you can!
if (e.Alt && e.KeyCode == Keys.F1)
Hope it's not too late, but I didn't got your post.
All the best,

Thanks, it's not too late.

Excuse me for being brief, but it is self explanatory.
So I make a query with linQ, and then try to make a 2nd query on the previous results, but there i get an error.
List<clsHotel> q = from d in dbGet.Hotels()
select d;<br />
<br />
if (chkHalfpension.Checked) {<br />
List<clsHotel> z = from x in q
where x.Naam == "Bon jour" <br />
select x;<br />
}
It returns the following error on that line:
Error 1 Cannot implicitly convert type 'System.Collections.Generic.IEnumerable<hotelmanager.data.clshotel>' to 'System.Collections.Generic.List<hotelmanager.data.clshotel>'. An explicit conversion exists (are you missing a cast?)
If anyone could please help.
Thanks in advance !
-- Edit --
The weird thing is:
This code also doesnt works:
List<clsHotel> q = from d in dbGet.Hotels()
select d;<br />
<br />
List<clsHotel> z = from vx in dbGet.Hotels()
select vx;
It throws the same error, but the code is the same :s
Guess it's an bug in c#3.0 ?

instead of list, have you tried var?
|
|
|
|
|
Yes, keeps saying the same error.
I guess you can't do 2 of that select things in the same function, wich is to bad 
|
|
|
|
|
Have you tried IEnumerable < string > < == remove spaces
|
|
|
|
|
This works ! (except i used clsHotel class, not string)
Thanks alot edboe !

Another option would be to create each search in a separate function/method.

What i want to be able to do is change a Color that i get from a method to a lighter version. E.g: If its red, make it a lighter shade of red.
Any ideas how i'd do this?
Regards,
Gareth.

Hello,
I think this should do it.
Color _lightcolor = ControlPaint.Light(Color.Red);
Hope that helped you.
All the best,

Hi
If I output the result of a web-method as a struct defined in my web-service, how do I then use that outputted result (i.e. the struct and its properties, methods, etc.) in the calling client application?
Here is the struct:
public struct DataType_Shop_SKU
{
public Int32 SKUID;
public String Name;
public String WebDescription;
}
Here's the web-method:
public DataType_Shop_SKU GetSKU(int SKUID)
{
clsShop Shop = new clsShop();
try
{
MyDataTypeSKU = Shop.GetSKUBySKUID(SKUID); // populates the struct
}
Thank you for your help.

Make a dll of the struct and refer it to both client and the server.

Hi All,
Given a string filename, eg:
string filename = @"c:\my folder\my second folder\myfile.txt";
Is there a neat-o way of getting the directory that the file is in, other than using string manipulation or regular expressions?
I'd expected that there would be a File class with a (read-only) property of Directory, such that one could get the directory a bit like this:-
string directory = new File(@"c:\my folder\my second folder\myfile.txt").Directory;
but I cannot find anything like that.
Thanks
Jon

Take a look at the System.IO.Path class which has a static method to do exactly what you want.

Excellent! Thanks Jamie, perfect.

Have a look at the System.IO.Path class.
