Sorry, but I do not understand the point of controlling a port from remote location. This means you need a driver that listens to a specific port for remote control commands. What I was sugesting is to control a remote application- not port- and let that application control port. Should not it work for your purpose?
|
|
|
|
|
yes that should do the trick!
this was the point of the thread, to get posible ideas from others who have atempted it and then decide which way will suite our needs best
but your idea sounds like it will work perfectly...
another colegue of mine asked me to look into the topic and posibility of controlling a com port remotely...
thanx for your idea

Hi,
I have ClassA, ClassB. ClassB inherits ClassA.
How do I de-couple these classes, so that, If i make changes to ClassA, ClassB wont be affected?.
and I wont have to modify ClassB(rebuild)
how to generalize?
-Pete

By causing them not to be inherited from one another ? Perhaps define a common interface that defines the part you want to exist between the two classes.

}
---- Set the CMBDecoreKind SelectItem ---
DataRow[] aRows=dsAcc.Tables["ACCTYPE"].Select("ACC_TYPE_ID=" + AccTypeID);
foreach (DataRow dr in aRows)

I have a set of MP4 files on a remote FTP server. My application has to show a preview of that clips before user can download that. For displaying the preview, I am downloading the clip to a temporary location. This temporary file will be deleted once the preview finishes. But I feel insecurity in this method as user can copy the file from temporary location once they come to know the location.
I am looking for a method which I can get the video contents to a stream and supply that to the player. I am using windows media player wrapped int to my own custom control. Is there anyway to do this ? I am using WebClient class for accessing the file. It provides methods to read data to a stream, but I don't know how to set this to player. Any ideas ?

I think you need to use the HTTP, RTSP, or MMS protocols for WMP to support streaming. I think you should definitely look into hosting your files on a server with those protocols opposed to FTP. There might be a way to have an ASX file point to the files on the FTP server, but I'm not 100% sure of that.
Good Luck.

That sounds great. I have some problem with using HTTP as users will be able to download the video directly from the server specifying URL. I will look into MMS and RTSP which is totally new to me. Thanks again.

call fortran dll winthin c#, when outnumbering, prompt:stack overflow
I don't know how to setup the size of stack in c#
|
|
|
|
|
The size of the stack is irrelevant, I reckon. Sounds like your code is getting into a recursive loop that doesn't end.

Hi all,
I have written a Application in C#. Its previous versions used to run on the Laptop.
However after including the dll(Interop.ActiveDs.dll) to find out the user name and the netId, the applciation fails to launch on several Laptops. however, few people are able to use it on thier PC's.
Does anyone have a clue as to why it does not work?
I ensured that .NET Framework is present on the Laptops. But it still does not work.
Thanks,
Nazia.

You need to provide more info than 'it fails to launch' and you need to work out what the machines it won't run on, have in common. It's not very probable that the issue is that they are notebooks.

Hello Christian,
The application works on few computers and does not work on the others.
I work on ASIA domain while the client for whom the application is written works in EUROPE domain. Even there, the application does not work on Laptop's.
I am not aware of what is amiss.
Can you tell me what are the features i need to look into?
Thanks.

Hello I'm working on a semi-script engine (using Reflection) and I have this class:
<code>
public enum LogicalOperator { EQL, NEQ, GTR, LSS, LEQ, GEQ };
public class Condition
{
public string instancename, fieldname;
public LogicalOperator logic;
public object value;
public Condition(string instancename, string fieldname, LogicalOperator logic, object value)
{
this.instancename = instancename;
this.fieldname = fieldname;
this.logic = logic;
this.value = value;
}
public Condition()
{
}
public bool Eval(object target)
{
object myValue = null;
try
{
myValue = target.GetType().GetField(this.fieldname).GetValue(target);
if (myValue == null)
{
myValue = target.GetType().GetProperty(this.fieldname).GetValue(target, null);
}
switch (this.logic)
{
case LogicalOperator.EQL: return myValue == this.value;
case LogicalOperator.NEQ: return myValue != this.value;
case LogicalOperator.GTR: return (float)myValue > (float)this.value;
case LogicalOperator.LSS: return (float)myValue < (float)this.value;
case LogicalOperator.LEQ: return (float)myValue <= (float)this.value;
case LogicalOperator.GEQ: return (float)myValue >= (float)this.value;
default: return false;
}
}
catch (NullReferenceException)
{
return false;
}
}
}
</code>
This works fine, but the problem is that I need some function like <i>GetObjectInstanceByName(this.instancename</i>), where instancename is a string and the return value is the instance as object.
I.e.: <i>Button myButton = GetObjectInstanceByName("Form1.button1") as Button;</i>
I've been surfering the net but I've don't found anything. How can I do this?
Thanks

You can call a constructor with reflection, I thought.
