What's actually in the byte array?
You're swallowed exceptions in serialisation which is a really bad idea as it makes it impossible to tell if that failed.

The problem is that one of the keys you attempt to read doesn't match the name of the key that you write. It's generally a bad idea to use strings like this in serialisation code - you should really use constants. That way, you make sure that the string is the same on the input and the output.
This code has the problem:
[Serializable()]
public class index
{
public int x;
public int y;
public int indexOfTargetCube;
public byte direct;
public index()
{
}
public index (SerializationInfo info, StreamingContext ctxt)
{
x = (int)info.GetValue("x", typeof(int));
y = (int)info.GetValue("y", typeof(int));
indexOfTargetCube = (int)info.GetValue("temp", typeof(int));
direct=(byte)info.GetValue("isConnected",typeof(byte));
}
public void GetObjectData(SerializationInfo info, StreamingContext ctxt)
{
info.AddValue("x", x);
info.AddValue("y", y);
info.AddValue("indexOfTargetCube", indexOfTargetCube);
info.AddValue("direct", direct);
}
}
You use indexOfTargetCube when you write the data out, and you use temp when you read the same item back in.

Hi
I'm working on improving a GUI on an application, I have a tabconrol with many pages, I want to put a background Image instead of the unique color which appear behind, I didn't find any property to do it .. Is there any way ??
your help is really appreciated,
thanks

Tab control? If you are using Pivot view, you can set a background image as described here[^].

Hi thanks for the answer,apparently this is for windows phone, I'm using a smart device, windows mobile version 6
|
|
|
|
|
What version of Windows Mobile are you using?
|
|
|
|
|
Hi I'm using the mobile 6 version, visual studio 2008, .NEt 3.5
|
|
|
|
|
I don't believe you can do this with the default WinMo TabControl, and I'm not aware of any open source implementations that provide this functionality. You might want to look at the controls at Resco[^]

There is a software called "advanced uninstaller pro 11" , I want to know is how the software dynamic menus can be built with C #? My English is poor, please reply with fluent English 
This is software that addresses:advanceduninstaller
|
|
|
|
|
Instead of linking us to a website (which makes me wonder whether this is just a spam pseudo-ad), describe your problem. Dynamic menus could mean a lot of things. What do you mean by dynamic? (Different content each time you show them? Ability to change content while it's visible? Built once on app startup?) And what environment (i.e. web, WinForms, WPF, Silverlight etc)?
|
|
|
|
|
Surely this is not spam. I mean that would like the software advanced uninstaller, Means when we click on one of the menus with animation-like state of being into another.

I would also suggest you to post this question in their Forum for better and quick answer.

Hi people,
I've a doubt:
Today I work with Java, but I started teaching C# to beginners.
I created two forms, each one has a button on the middle of the form. When I click the button of the first form, the second form appears and the first form disappears. When I click the button from second form, (the one that appeared), the first form appears and the second form disappears.
It's just to teach how the methods .Show() and .Hide() works. Now it's working, but I've a problem: When my software is running over Visual Studio, normally if I were, for example, working with just a form, clicking on (X) to close the app, the IDE came back to development mode. But on my app, after I show some punch of clicks to go to a form and to came back to the other, even if I had been on any of the forms (first or second), if I click to close the app, It does not happens.... I have to click Shift+Control+F5 to came back to development mode, and still doesn't happens again, the form appears, and I have to close it (again), so THEN I go to development mode... Weird.... Could someone help-me ?
I'm hiding the first form, and opening the other using
<pre lang="c#">
Form form2 = new Form();
form2.Show();
this.Hide();
and inside the Form2:
<pre lang="c#">
Form form1 = new Form();
form1.Show();
this.Hide();
|
|
|
|
|
Process won't quit till the main form and all foreground threads finishes executing. If you close the Form1, it should get closed properly. Is that happening?

I don't mean to sound negative, but I don't think you should teach C# (yet) if you still have these kind of questions.
That doesn't mean you're a bad programmer, but I think you still lack the thorough .Net knowledge to teach it.
I'm working with .Net for almost 10 year now (since 1.0) and I wouldn't even want to teach it.

I totally agree with you.
Think! Don't write a line of code unless you absolutely need to.
|

You didn't close the startup form. You closed another INSTANCE of Form1.
You should not have used Show to show Form2. You should have used ShowDialog. That way, when Form2 closes, the original instance of Form1 gets control back. Though, the down-side to using this is that Form1 code blocks until Form2 closes.
Form2 form2 = new Form();
this.Hide();
form2.ShowDialog(); ' Blocks until form2 closes
this.Show();

Very thank's Mr. Kreskowiak. You helped-me very very much!!! Thank's Again!, and Best Regards!

As far as teaching this class, you and your students are still screwed. You don't have the prerequisite knowledge to teach this stuff. You're just going to be guessing at how things work and the only thing worse that not knowing anything at all about what you're learning is being completely misinformed about what you're learning, and that's the path you're leading these students down.
|

This is entirely the wrong way to demonstrate Show/Hide. Multi-form UIs are difficult to get right, and coding up the example that you are using correctly will introduce a whole bunch of concepts (about main forms, the application loop and Program.cs) that are not relevant to the point.
Just have a button on your main form that shows or hides the secondary one.
And why are you creating a new instance each time? Such an elementary misunderstanding of objects and classes indicates that you shouldn't really be teaching people about any OO environment.
|

|
|
|
A windows App process will not close until the Main method exits.
And you're creating a new instance of the forms on each button click. What you should ideally be doing is to create a private member of Form2 in Form1 and instantiate it in the Form1's constructor or when it is first used (and vice versa for Form2).

Hi All,
I was developed a c# windows application and now I want to create a setup package for it that contains the SQL SERVER and .NetFramework and the application itself.

I don't think you can package SQL server with your application. Not sure if the license allows to do this.

I wrote one .net c++ dll,and reference it in an c# winform program .Prompt the following error:
title: BadImageFormatException was unhandled
content:
Could not load file or assembly “CppDll, Version=1.0.4798.31848, Culture=neutral, PublicKeyToken=null”or one of its dependencies.
the Default cpu settings is anycpu,when i change it to x64,the result is the same.but when i change it to x86 it can work well.
This is a very simple test example code:
part dll code:
namespace CppDll {
public ref class Class1
{
};
}
part exe code:
public Form1()
{
CppDll.Class1 cls = new CppDll.Class1();
InitializeComponent();
}

Where are you changing? In the C# project?
