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

Keys shortcuts problem

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.

Khalid

Hello,

Yes you can!

if (e.Alt && e.KeyCode == Keys.F1)

Hope it's not too late, but I didn't got your post.

Linq - Problems with conversion [modified]

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()  // dbGet.Hotels() returns List<clsHotel><br />
                    select d;<br />
<br />
            if (chkHalfpension.Checked) {<br />
                List<clsHotel> z = from x in q     // Error occures here on q<br />
                                            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()  // dbGet.Hotels() returns List<clsHotel><br />
                    select d;<br />
<br />
                List<clsHotel> z = from vx in dbGet.Hotels()   // also gives error here<br />
                                   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?

Storme2-Nov-06 6:52

Storme

2-Nov-06 6:52

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 Frown | :(

ed^nrgc2-Nov-06 6:55

2-Nov-06 6:55

Have you tried IEnumerable < string > < == remove spaces

Changing a Color on the fly

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,

Using a struct passed from a C# web service at the client

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.

Directory from File Name

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.
