System.AppDomain dom = System.AppDomain.CreateDomain("newDomain");
dom.Load(arraybyte); not work
do not start.
and use this code:
byte[] arraybyte = System.IO.File.ReadAllBytes("app.exe"); Ok
System.Reflection.Assembly.Load(arraybyte); not work
How it need work?
Help please.

Is app.exe a .NET exe? If not, you cant do that.
|
|
|
|
|
app.exe is a .NET .
I don't know how to do next step.
Application .Net do not start from byte[].
Please help me.

Is there a reason you couldn't just call System.Diagnostics.Process.Start() ?
|
|
|
|
|
Class System.Diagnostics.Process.Start() need String type
But my application in byte[].
I don't start my application from hard disk.
My application in memory.
|
|
|
|
|
byte[] arraybyte = System.IO.File.ReadAllBytes("app.exe");
System.AppDomain dom = System.AppDomain.CreateDomain("newDomain");
Assembly assembly = dom.Load(arraybyte);
assembly.EntryPoint.Invoke(null, null);
That calls the Main() method.
|
|
|
|
|
I run this code.
byte[] arraybyte = System.IO.File.ReadAllBytes("app.exe");
System.AppDomain dom = System.AppDomain.CreateDomain("newDomain");
Assembly assembly = dom.Load(arraybyte);
assembly.EntryPoint.Invoke(null, null);
But in line
assembly.EntryPoint.Invoke(null, null);
have runtimeerror:
"TargetInvocationException was unhandled
Exception has been thrown by the target of an invocation."
Please help me!

Read the exception's InnerException. That'll tell you the actual error.

My code :

System.AppDomain dom = System.AppDomain.CreateDomain("newDomain");
Assembly assembly = dom.Load(arraybyte);
assembly.EntryPoint.Invoke(null, null);
}
catch (Exception e)
{
string st = e.InnerException.ToString();
}
}
}
}
st :

Please help me!

I can't run that since I have neither the other portion of the form nor zshchita.exe, but just judging from the exception, it looks like you have to remove the line that calls Application.SetCompatibleTextRenderingDefault from zshchita.exe. It's probably in Main().

My be out of memory?
Any application i was run in TotalComander and Ok result.
But from my application is error.
If this veri hard then stop this idea?
I don't know how to do this.
But i was veri wont to do this!
God bless you. He leves you veri mach.
|

I'm pretty sure you can fix it by deleting the Application.SetCompatibleTextRenderingDefault() from the other exe.
|
|
|
|

i deleting this but problem don't go out.
Next message was this :
System.InvalidOperationException: Starting a second message loop on a single thread is not a valid operation. Use Form.ShowDialog instead.
at System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context)
at System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context)
at System.Windows.Forms.Application.Run(Form mainForm)
at Bblank.Program.Main()

|
|
|

Try what the error says...
On the line where it says Application.Run(), change it to form.ShowDialog().

hi all,
let's assume i have form named mehmet and a mainmenustrip on that form like this:
'Properties'
>property1
>property2
>property3
>...
mehmet.MainMenuStrip.Items[0].ToString() gives me the name : <properties>
how can i get any name under Properties ? what should i write instead of mehmet.MainMenuStrip.Items[0].ToString() to get property3 as a result ¿
|
|
|
|
|
mainMenuStrip.Items[0]?
what do you mean?
do you want it's name? what's written in it?
if you want what's written it's not ToString... it's Text...

Your question isn't very clear. What is you are trying to do?

Hello guys,
Can u suggest me a command in C# similar to GetObject in VB6.0
|
|
|
|
|
What does GetObject in VB6.0 do?
"On two occasions, I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able to rightly apprehend the kind of confusion of ideas that could provoke such a question."

GetObject in VB:
if you are running a third party app from ur code lets assume 'mspaint' and due to some reason ur system crashes and is not able to close the instance of 'mspaint' which will now run in background and consume memory.
so GetObject in VB will get this running instance of 'mspaint' and reuse it instead of starting a new instance.
Sorry, i was not clear earlier as this is for the 1st time i am posting a query .... will take care of this in future
Can u pls suggest a similar function in C#
Thanks in Advance

Hi!
You might want to take a look at Marshal.GetActiveObject()[^]

Good day everyone,
I've been doing a handwriting program. User can use mouse pointer to draw lines and eraser lines
I use 2 methods AddPoint and RemovePoint to add points when user draw lines and remove points when user erase lines by using ArrayList pointArray.
But they're not working
Please help me if you are interested in this program.
Thanks so much
