Not sure what else I can give you. So I've shown you where the options are to change the Fonts & Colours of the text editor. Looking through the display items, I can only assume that the "Collapsible Text" is what you need. Google may be your friend in finding out what each display item is

Hi,
I don't know whether this is the right place to ask this question.
I have an executable file that I want to run remotely. When I double Click the file and when I use the command prompt, It starts fine.It also runs fine when I use Task Manager. I included the file in the system path and when I run it through the run utility and when I run it in the command prompt(without giving it its full path), It runs but not as expected i.e some of the buttons on the running form are disabled.
Running the file through the System.Diagnostics.Process.Start function of C# has exactly the same problem. What I want is to run it through the System.Diagnostics.Process.Start on a remote XP machine.

It sounds to me like a bug in the program and not a remote issue. The fact that it performs differently when running it from cmd then when double clicking it suggest that to me. You could try adding a pause on startup, running it from the command line, attach a debuger and unpause it. Then you can see why the buttons are disabled.

Hi
i am using 2 form first from is logo 2nd is my application, i want to first show my logo from then after few mints the 2nd form is show and 1st form is close, i am using timer but not working correctly and my coding is below.
private void logo_Load(object sender, EventArgs e)
{
Timer timer = new Timer();
timer.Tick += new EventHandler(timer1_Tick);
timer.Interval = (1000) * (1);
timer.Enabled = true;
timer.Start();
}
private void timer1_Tick(object sender, EventArgs e)
{
Form1 frm = new Form1();
if (timer1.Interval == 1000)
{
this.Hide();
frm.Show();
timer1.Enabled = false;
}

What you are trying to do is implement a splash screen - have a look at this[^], it may be more than you want, but it will show you how to do it!

link is very good but i need small coding

Ok my friend i found a solution for your problem with a short code 
you made a simple mistake in the form1_load method, it should be left empty!
here is the full code of the program (I included the full code page!):
public partial class Form2 : Form
{
Form1 F = new Form1();
public Form2()
{
InitializeComponent();
}
private void timer1_Tick(object sender, EventArgs e)
{
int A = 1000; // represents number of seconds before Form2 is shown. each 1000 = 1 sec.
for (int i = 0; i < A; i++)
{
this.Hide();
F.Show();
}
this.timer1.Stop();
this.timer1.Enabled = false;
}
}

Hi everyone. I'm trying to invoke a constructor through reflection, with no luck.
Basically, I have an object that I want to clone, so I look up the copy constructor for its type and then want to invoke it. Here's what I have:
public Object clone(Object toClone) {
MethodBase copyConstructor = type.GetConstructor(new Type[] { toClone.GetType() });
return method.Invoke(toClone, new object[] { toClone });
}
I call the above method like so:
List<int> list = new List<int>(new int[] { 0, 1, 2 });
List<int> clone = (List<int>) clone(list);
Now, notice the invoke method I'm using is MethodBase's invoke. ConstructorInfo provides an invoke method that does work if invoked like this:
return ((ConstructorInfo) method).Invoke(new object[] { toClone });
However, I want to use MethodBase's method, because in reality instead of looking up the copy constructor every time I will store it in a dictionary, and the dictionary contains both methods and constructors, so it's a Dictionary<MethodBase>, not Dictionary<ConstructorInfo>.
I could of course cast to ConstructorInfo as I do above, but I'd rather avoid the casting and use the MethodBase method directly. I just can't figure out the right parameters.
Any help? Thanks so much.

Dunno. If casting works, you might as well do that.
Also, why not make the method generic?

Well, I know I can, but I don't want to. This method will be called pretty often and I don't want to be doing any unnecessary operations (such as casting) that may impact performance.
PIEBALDconsult wrote: Also, why not make the method generic?
How will that help? Can you be more specific?
Thanks.

That type of casting isn't an operation.
blackblizzard wrote: How will that help?
The caller won't have to cast the result; it would be done internally.
blackblizzard wrote: will be called pretty often
With how many different types of object? If only a few, then maybe write specific cloners for them.

I'd say it is. "A cast explicitly invokes the conversion operator from one type to another. (...)"[^]. It results in a IL cast class[^] instruction. How is it not an operation?
PIEBALDconsult wrote: The caller won't have to cast the result; it would be done internally.
I still don't see that. We're always casting to ConstructorInfo. I think you're confusing the type of the object we want to clone, which may be anything, with the type of the method we use for cloning, which may be either ConstructorInfo or MethodInfo (both of which are subclasses of MethodBase) and isn't known a priori, since it depends on whether the type of the object has a copy constructor. Or maybe I'm the one that is confused; in that case please explain.
PIEBALDconsult wrote: With how many different types of object? If only a few, then maybe write specific cloners for them.
With any type of object. It isn't known a priori. If it was I would already know whether the types of the objects have copy constructor or Clone methods, and this wouldn't be a problem.

In many cases (like yours) no conversion is necessary; if I have an instance of class X, but pass it in as Object, and cast it back to X, then there is no conversion -- that's what I meant.
blackblizzard wrote: depends on whether the type of the object has a copy constructor
I don't think you said that originally, but I see what you mean.
I also tested it and see that you are correct; Invoke doesn't seem to behave as documented. Now I'm intrigued...

Ah, alright. Well, that's good news. Although I'd still like to know how to do it without the cast, just for sake of knowing
PIEBALDconsult wrote: I don't think you said that originally, but I see what you mean.
True, I didn't. I didn't want to include extraneous info, and I was asking something very specific... But yeah, I forgot you didn't know about that.

Great. Now that makes two of us

I tried to write overloaded methods -- one for ConstructorInfo, one for MethodInfo -- but it didn't compile; it might with C# v4.0
Still, even if it worked there'd be the extra method call which would likely be slower than the cast.

Aha! It is documented:
"
Return Value
Type: System..::.Object
An object containing the return value of the invoked method, or nullNothingnullptra null reference (Nothing in Visual Basic) in the case of a constructor.
"
So I think you have to cast.
Here's a little something I whipped up to show a generic method to do it:
private static readonly System.Collections.Generic.Dictionary<System.Type,System.Reflection.MethodBase> dic ;
static Test
(
)
{
dic = new System.Collections.Generic.Dictionary<System.Type,System.Reflection.MethodBase>() ;
return ;
}
public static T
Clone<T>
(
this T Source
)
where T : class
{
System.Type t = typeof(T) ;
System.Reflection.MethodBase m ;
if ( !dic.ContainsKey ( t ) )
{
System.Type[] part = new System.Type[] { t } ;
m = t.GetMethod ( "Clone" , part ) ;
if ( ( m == null ) || ( ((System.Reflection.MethodInfo) m).ReturnType != t ) )
{
m = t.GetConstructor ( part ) ;
if ( m == null )
{
throw ( new System.Exception ( "blah blah blah" ) ) ;
}
}
dic [ t ] = m ;
}
else
{
m = dic [ t ] ;
}
T result ;
if ( m.IsConstructor )
{
result = (T) ((System.Reflection.ConstructorInfo) m).Invoke ( new object[] { Source } ) ;
}
else
{
result = (T) m.Invoke ( Source , new object[] { Source } ) ;
}
return ( result ) ;
}

So I think you have to cast.
Ah, I see. That's a bit weird, IMHO, but there you go . Good to get that out of the way, thanks for the info
As for your code, yep, that's pretty much what I was doing except for the generics. However the caller doesn't know the type of the object it's going to clone, so I'll keep it non-generic. But thanks for the alternative
Finally, they gave me a very good answer at Stack Overflow[^] using Func<,> instead of MethodBase. It's way more elegant (and very probably more efficient) so I'm adopting that solution.
Thanks for your input
(so many smiley faces! but there you go)

Hi,
I use VS2010 + windows forms for a few months, so i can't try WPF, my application is too developped to start from 0.
So I would like to know how to totally edit the skins of combobox, buttons...
To not have windows XP's theme for example.
For example, if I have all my design on Photoshop, I should edit skins of combobox in order to do the same as the design.
I've seen some application which were doing that, but they were really expensive.
So I ask you: How i can create a skin? or edit vista's Style, to have a comboBox totally personnalized.
Thanks.

If you want to send a mail to group in that case the group should have a defined email address in the Global Address List. Set the group email address in To list of the email.
If you are looking for code to send email using c# then you can check this article in CP

hello
I've couple core 32 bit dll - trying to package them under a Windows Service running on 64 bit Windows. Is this feasible?
Thanks
dev

A 32 bit application can run on 64-bit windows, these applications are handled in a different way, but the communication between 32-bit and 64 bit modules can’t happen directly (You need to do some workaround for that). It will be better if you try to migrate it to 64-bit.
