You can use obj.GetType() to find out what type object actually is. You can then cast it to the proper type.
Or you can do something like:
if(obj is int)
int x = (int)obj;
else if(obj is string)
string x = (string)obj;
else ..

Convert.ToInt32(obj);
}

Console.WriteLine(ex.Message)
}

Here is the situation.
I have a Form, called Form1 that contains a button, this button is marked as private.
I have another Form, called Form2 the inherits from Form1.
I Want Form2 to be able to Show and hide the button in the base class, without exposing the button as protected / or public.
I Have created a public property on Form1 which has Get/Set into button.Visible property. All should work ok i can hear you shouting.
In the form2 designer, i can see the property mentioned above, and i can change its value, and the button obediantly shows and hides it self as expected. The problem is that When i set enabled to true, it adds code to the designer generated section, which speifically sets my property to true, and when i set it to false, it removes this code, but it does Not add code to set it to false. The defualt value of the property is set to true, but this has no effect.
I realise i can call this property in my form load, or in a constructor, but i would like to get the design time support. Other properties such as Enable work fine.
Any idas?

Try to add DesignerSerializationVisibility attribute:
<br />
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]<br />
public bool Description<br />
{<br />
get<br />
{<br />
return myButton.Visible;<br />
}<br />
set<br />
{<br />
myButton.Visible = value;<br />
}<br />
}<br />

Unfortunately this does not have any effect. I believe that for some reason the designer believes the default value is set to false, so that when i set it to false, it does not add any code.

In framework 1.1 I used to do Assembly.GetTypes() and get everything, web pages, web services, classes.
In framework 2.0 it’s not the same story. There are App_code…dll, App_Global.dll, App_web…dll.
The only thing I was able to get is the App_Code by ReflectionOnlyLoadFrom() method.
Is there a way to get everything like I did before?

Code :
internal void Run()
{
AppDomain curDomain = AppDomain.CurrentDomain;
curDomain.ReflectionOnlyAssemblyResolve += new ResolveEventHandler(MyReflectionOnlyResolveEventHandler);
string assemblyPath = Path.GetFullPath(assembly.Location);
m_rootAssembly = assemblyPath;
Assembly asm = Assembly.ReflectionOnlyLoadFrom(assemblyPath);
// force loading all the dependencies
Type[] types = asm.GetTypes();
// show reflection only assemblies in current appdomain
Console.WriteLine("---- Inspection Context ----");
foreach (Assembly a in curDomain.ReflectionOnlyGetAssemblies())
{
Console.WriteLine("Assembly Location: {0}", a.Location);
Console.WriteLine("Assembly Name: {0}", a.FullName);
Console.WriteLine();
}
}
private Assembly MyReflectionOnlyResolveEventHandler(object sender, ResolveEventArgs args)
{
AssemblyName name = new AssemblyName(args.Name);
String asmToCheck = Path.GetDirectoryName(m_rootAssembly) + "\\" + name.Name + ".dll";
if (File.Exists(asmToCheck))
{
return Assembly.ReflectionOnlyLoadFrom(asmToCheck);
}
return Assembly.ReflectionOnlyLoad(args.Name);
}

I am writing a .net assembly that contains several UserControls. When a control is clicked, I would like to fire a message to the parent window so it can do something.
The parent window is in a different assembly, and the UserControl knows nothing about the parent.
How can I call the parent?
In MFC/Win32 I could send a message, but I'm new to this C#.NET thing. Is there a standard method to do this?

i think u can use the on click event of the control
and use the SendMessage(hwnd,wparam,lparam,..) to send
a message to the parent window
Regards,
Pramod

The UserControl needs to raise an event. Any host (parent) can choose to respond to the event if it wants to. This is the .NET way of doing things and it's much better than the old SendMessage way.
Look up events and delegates in the documentation.

There is no "simple" way to do this. You can find an example of RAW printing here[^] on MSDN. The code is in VB.NET, but is easily convertable to C#.

Hi all,
Here is the code:
\\----------------------------------------
public void DisplayButtons()
{
string idName = "id" + j;
string divName = "divNamee" + j;
string divId = "divIdd" + j;
string StyleStr = "visibility:visible; position:absolute; left:" + xPosCityValue + "; top:" + yPosCityValue + ";";
Response.Write("<DIV NAME = '" + divName + "' ID = '" + divId + "' runat = \"server\" STYLE = '" + StyleStr + "'>" + "<input type='image' runat='server' SRC='bulletNew.gif' ALT='" + curCityName + "' id='Image1' onserverclick='Image1_ServerClick'>" + "</DIV>");
}
protected void Image1_ServerClick(object sender, ImageClickEventArgs e)
{
Response.Write("Hello");
}
\\----------------------------------------
On clicking the imagebutton, the event doesnt trigger. I have no idea where I am going wrong. Someone Please help me. This is really urgent.

That is because you are not using a server control. If you simply write out the html code for the control, the runat and onserverclick properties simply ends up in the html code, where they are totally meningless. The runat and onserverclick properies only work if you have them in code that is parsed into the page.
In this case I would simply create server objects for the elements, add the event to the OnClickproperty of the button, and add the objects into a Controls collection of an element in the page.

Thank you for the prompt reply. I did not get you clearly. I would be very happy if you could brief little more on this with some example code. I once again thank you for the reply. (I am waiting for your reply).

What was it that you didn't understand?

b { font-weight: normal; }

| Response.Write(" " + "runat='server' SRC='bulletNew.gif' ALT='" + curCityName + "' id='Image1' onserverclick='Image1_ServerClick'>" + " ");
}
You said that i need to make the "image button" as a server control, which I had already done in the above code (the attribute in the bold text).
Also, I want to ask whether it is possible to call C# method from javascript.
Thanks in advance. Please reply soon. I am eagerly awaiting.
Nitya.

No, it's not a server control. It's just some text in a string. Just because the string contains "runat='server'" doesn't mean that anything happens. The string could just as well contain "kill all humans", but that wouldn't happen either.
To be a server control it has to be a real object, in this case an HtmlInputImage object.
There are generally two ways of creating server controls:
1. Put the tag in the aspx page so that it is parsed into the Page object.
2. Create the object in the code behind and add it to the page structure.

Not directly. Consider these two rules:
1. The server side code and the client side code never exist in the same place.
2. The server side code and the client side code never exist at the same time.
If you want a Javascript to make anything happen on the server, you have to post the page back to the server and make the C# code detect what it is supposed to do.
