Hi all,

I am developing a couple of web services for work. Most of the methods return custom classes but I want one of them to just return a 'string' (either "OK" or "NOTOK").

The problem is that, whilst with custom classes the webservice's XML's tags are named according to the variable name (for example: <hotelsummary><hotelid>5 ... where HotelSummary is a type but HotelID is the variable name), with strings the XML returned is <string>OK.

Is it possible to rename the tags to display, for example, <hotelcheck>OK instead of the datatype?

Thanks a lot.

Why not use bool then? Return True/false

I don't think you can rename it. I am not sure though.

First, unless you are planning on expanding your status messages later, I would suggest using a boolean.

Second, sounds like you might be able to use an enumeration for this:

public enum Status
{
  OK,
  NOTOK
}

Then you would be able to say Status.OK or Status.NOTOK

Hope this helps,
Chris

Hi Chris,

Yes thanks a lot. The enum was exactly what we needed, especially since we are able to expand the responses whenever needed now.

how can i use txtNoPersoneli when this is in other form?

Re: use control in other form

If txtNoPersoneli's access modifier is public then you should be able to access it through otherforminstance.txtNoPersoneli

Better still, create events in otherform that are rasied when whatever your interested in with txtNoPersoneli occurs, and subscribe to these in the initial form.

You have to access it through an instance of the second form. For example, if the form is called Form2 then:

Form2 form2 = new Form2();
// any other stuff here
form2.txtNoPersoneli.Text = "Text";

Whoever univoted this - I agree that it's not best practice and if you look at my previous reply I did suggest using events (implies delegates too). The question in response to that from the OP was specifically on the unrecommended way, to which I gave an accurate and working response! Dead | X|

You change the access modifier to public, but it is not recommended as it breaks OO rules. Use delegates to communicate between forms. CP has an article on this subject.

listen,

you have to use delegates, search: transfer data between form here in codeproject.

you may want to drop the idea of using more than 1 form Frown | :(

use parentform/childform method
or
1form + 10usercontrols (usercontrols that load in form like page, i use it a lot) method

i use delegates, see the following exemple
(here i trigger a text msg FROM usercontrol IN form):

in userform

public delegate void Delegate_TransferPageInfo(string msg);
public event Delegate_TransferPageInfo Event_TransferPageInfo;

private void ToolStripButton_Add_Click(object sender, EventArgs e)
{...
Event_DriverPageInfo("ERROR: invalid birth date");//trigger
...}

in form

private void Form_Main_Load(object sender, EventArgs e)
{...
UserControl_DriverPage_Child.Event_DriverPageInfo += new UserControl_DriverPage.Delegate_DriverPageInfo(Page_Info); 
...}
protected void Page_Info(string msg)
{
ToolStripStatusLabel_MainInfo.Text = msg;
}

can´t help you more!!! Poke tongue | ;-P

I don't know of a standard path where a webcam would store all the captured images. The app might store it in "my pictures", or in a folder where the app is installed. Different webcam applications may use different folders, don't you think? Roll eyes | :rolleyes:

So, have an option in your application where the user can specify the path on where to store the captured images. It would be ideal to create a folder, within the "My Pictures" folder, and store the images there by default.

There's no default saving location. Create a folder within My pictures like "My Captures" and store it within that folder.

Umm... So, you are not writing an utility for a webcam yourself? Are you just intending to find the default location where this HP webcam stores the captured images? If yes, there must be an app that should be controlling it. Why not check with the settings?

WPF designer problem (MarkupExtension ctor confuse the VS2008SP1 designer)

Super Lloyd25-Sep-08 0:57

I have a simple experimental WPF application which works fine.
However the designer is broken.

I'm working on a MarkupExtension which takes 2 parameter, here is the faulty XAML snippet:

<TextBlock
  Text="{Binding}"
  Background="{Binding
                   Converter={local:Script
                                    'if(value%2==0) Brushes.Red; else Brushes.Green;', {x:Type Brushes}}}"/>

And I got this error message in the designer: "Problem Loading ........ <<Button: Reload the designer>>"

If I click on the button it fails and I got this error message in the error list:
Error 1 No constructor for type 'ScriptExtension' has 2 parameters. C:\Dev\Tests\ExpressionConverter\ExpressionConverter\Window1.xaml 13 43 ExpressionConverter

But problem is, my has extension has all the required parameters!!!
here is a snippet of its C# code...

public class ScriptExtension : MarkupExtension
{
   public ScriptExtension(string code) { Init(code); }
   public ScriptExtension(string code, Type t0) { Init(code, t0); }
   public ScriptExtension(string code, Type t0, Type t1) { Init(code, t0, t1); }
   public ScriptExtension(string code, Type t0, Type t1, Type t2) { Init(code, t0, t1, t2); }
   public ScriptExtension(string code, Type t0, Type t1, Type t2, Type t3) { Init(code, t0, t1, t2, t3); }
   public ScriptExtension(string code, Type t0, Type t1, Type t2, Type t3, Type t4) { Init(code, t0, t1, t2, t3, t4); }

   void Init(string code, params Type[] types)
   {
       ......
    }
    .....
}

Any tip / work around (to re-enable the designer) please?!?

hi all,

I have an exe and it contains some other dlls and using functions from that dll.I want to debug through that dll also using DbgCLR.exe.

can anybody help me to solve this problem?

Sorry, you cant. Neither will you be able to step thru any code in the external dll, nor will it work on native dlls (you need VS for that).
