Update Form while Retaining Access to It

I need to update a C# form with values read to it from another program in addition to changes from C# code while retaining the ability to edit text/combo boxes on a different part of the form from the updates. Right now, I can get the updates running, but am denied access to the form while the updates are occurring. How can I achieve this functionality?

Create an object dynamically for COM component witout reflection

Hi Guys,
How can we create an object for vb dll without reference and reflection in c#.
In VB.Net we have a method CreateObject(), but in C# we don't have such method. How can we achieve this in C#.

AFAIK, CreateObject also uses reflection like techniques to do its job.

I'm not sure how you can do without adding a reference, because C# is a statically typed language, which means that you have to have a type definition to compile.

Mocking interface methods with 2 dimensional array return types

Anonymous17-Oct-05 3:06

I have found a problem using Rhino (incidentally the same problem is occurring with NMock 1.1).

When I try to mock an interface which defines a method with a multi-dimensional array return type: creating the mock instance throws an error:

ClassLibrary1.SampleTest.MethodOnSampleTest_Rhino : System.TypeLoadException : Method MethodOnSample in type ProxyInterfaceSystemObject_ISample_IMockedObject_ISerializable from assembly DynamicAssemblyProxyGen, Version=0.0.0.0 does not have an implementation.

e.g.
namespace ClassLibrary1
{
public interface ISample
{
double[,] MethodOnSample(string StringArg);
}
}

using NMock;
using NUnit.Framework;
using Rhino.Mocks;

namespace ClassLibrary1
{
///

/// Summary description for SampleTest.
///

[TestFixture]
public class SampleTest
{
[Test]
public void MethodOnSampleTest_Rhino()
{
using (MockRepository mocks = new MockRepository())
{
ISample sample = (ISample) mocks.CreateMock(typeof(ISample));

Expect.Call(sample.MethodOnSample("Test"));

mocks.ReplayAll();

double[,] actual = sample.MethodOnSample("Test");

Assert.IsTrue(true);
}
}

[Test]
public void MethodOnSampleTest_NMock()
{
DynamicMock mock = new DynamicMock(typeof(ISample));

ISample mockInstance = (ISample) mock.MockInstance;

Assert.IsTrue(true);
}
}
}

Has anyone else experienced this problem and is there another mock object I can use to mock this interface?

Thanks.

hi my C#.net application has a Reminder pop up where a user enters reminder dates,name etc.
how do i make the reminder pop up from the date and time that it was set to?
here's what ive done
DataTable dtRemNow

conn=connection

SqlDatadapter da= new SqlDataAdapter("select * from reminders",conn);

da.fill(dtRemNow )

if(dtRemNow.Rows.Count > 0)
{
foreach(DataRow row1 in dtRemNow.Rows)
{
string strReminder = row1["rem date"].ToString;
if (strReminder .Length == 0) continue;
// get the date the reminder is due
DateTime dt = DateTime.Parse(strReminder);
TimeSpan tsRem = dt - DateTime.Now;
if(tsRem.TotalMilliseconds == 0)
{
}

}
}
dtRemNow.AcceptChanges();
if(dtRemNow.Rows.Count>0)
{
//show pop up for reminder
form.Popup(dtRemNow);
}
the pop up does not show Confused | :confused:

i would really appreciate if any of you can provide articles that include source code and examples
examples on creating reminder applications.

regards paula

This isn't quite a reminder application, but it might be useful for what you want to do.

You cannot create temporary volumes.

That was not a cross post, it was a reference.

It's quite ok to make a reference to another post. A cross post would spread the answers in two threads, while a reference keeps the answers in one single thread.

I want to get the header of a stream, which has been recieved into a array of byte.
Is there a safe method to get the header quickly?

Here is the header format:

length 4 bytes,
ID 4 bytes,
SN 12 bytes

Thanks!

If I understand correctly and you're trying to convert from a byte array to primitive integer types, you can use System.BitConverter:

<br />
// data as a byte array<br />
byte[] data = { 0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a }; // etc. etc.<br />
<br />
// convert the first 4 bytes to an integer<br />
int length = BitConverter.ToInt32(data, 0);<br />
<br />
// convert the next 4 bytes to integer<br />
int id = BitConverter.ToInt32(data, 4);<br />
<br />
// what is SN?

You can use the ReadBytes(int) function from the BinaryReader-class
