The only way I know to get the parameters like this is to use enterpriseServices and setup a context for the object. Here is an example of the technique.

I don't know of any way to get the actual parameters in regular code.

Hi all!
I need to create application to capture video and audio. To do this I use WMEncoder SDK. I use video tape recorder device connected through a COM port using the Sony RS422 protocol. Everything is good - I can capture and control my device. But I have a problem, when I try to change settings of encoder instance. Here is source:
<br />
WMEncoder Encoder;<br />
IWMEncSourceGroupCollection SrcGrpColl;<br />
IWMEncSourceGroup2 SrcGrp;<br />
IWMEncVideoSource2 SrcVid;<br />
IWMEncSource SrcAud;<br />
IWMEncDeviceControlCollection DCColl;<br />
IWMEncDeviceControl DControl;<br />
IWMEncDeviceControlPlugin DCPlugin;<br />
Encoder = new WMEncoder();<br />
SrcGrpColl = Encoder.SourceGroupCollection;<br />
SrcGrp = (IWMEncSourceGroup2) SrcGrpColl.Add("SG_1");<br />
SrcVid = (IWMEncVideoSource2) SrcGrp.AddSource(WMENC_SOURCE_TYPE.WMENC_VIDEO);<br />
SrcAud = SrcGrp.AddSource(WMENC_SOURCE_TYPE.WMENC_AUDIO);<br />
SrcVid.SetInput(_video, "Device", "" );
SrcAud.SetInput(_audio, "Device", "" );
IWMEncProfileCollection ProColl = Encoder.ProfileCollection;<br />
for (int i=0; i<ProColl.Count; i++)<br />
if (ProColl.Item(i).Name == _profile)<br />
{<br />
SrcGrp.set_Profile(ProColl.Item( i ));<br />
break;<br />
}<br />
DCColl = SrcGrp.DeviceControlCollection;<br />
DControl = DCColl.Add();<br />
DControl.SetInput(_device, "DeviceControl", "");<br />
Encoder.PrepareToEncode(true);<br />
DCPlugin=(IWMEncDeviceControlPlugin)DControl1.GetDeviceControlPlugin();<br />
So, when I try to change my settings (_video, _audio, _profile or _device) and do Encoder.PrepareToEncode(true) I catch an exception "It was not possible to find a valid source plug-in for the specified source". I try to set null for all of using vars after doing Encoder.PrepareToEncode(false), but have no result. Maybe somebody do something like this? Thanx for all advices.

While reading a large textfile with, I am going to implement a Progressbar. My question is how to determine the MAX value for this progressbar? So I can update the progressbar dynamically, while application is reading textfile.
|
|
|
|
|
Get the size of the file before you open it.
---
b { font-weight: normal; }
|
|
|
|
|
Sure, but how to determine actual file block and block size?
StreamReader and TextReader don't support a method to do it.
|
|
|
|
|
Block size? What do you mean?
---
b { font-weight: normal; }
|
|
|
|
|
File fIn = new File<br />
("C:\\dotNET Projects\\Namespaces\\EnumFiles\\ReadMe.txt");<br />
StreamReader strm = fIn.OpenText();<br />
<br />
string sLine;<br />
do<br />
{<br />
sLine = strm.ReadLine();<br />
AddItem(sLine);<br />
}<br />
while (sLine != null);<br />
strm.Close();<br />
<br />
Look at the code posted above. After sLine = strm.Readline, I want update the progressbar value but don't know the MAX value of this one before.
|
|
|
|
|
Get the size of the file in bytes, divide by two to get the number of chars. Finally use sLine.Length to get the number of chars you just read in.
|
|
|
|
|
Dividing the size by two to the the number of chars only works if the textfile is saved as 16 bit unicode. Most text files are ANSI or UTF-8, which uses 8 bit encoding.
---
b { font-weight: normal; }

Hi all,
I have a server with a server object and a UI (2 different classes). The server object must send UI update events to the UI. I want to have an instance of the shared object in my UI class.
If I create an object in the UI of the server object, it is not the same as the object that is retrieved when using Activator.GetObject(...);
Is there a way I can specify which object is shared using the Activator.GetObject function? What I want is to create a server object in my UI class. That object should also be shared when a client uses the function Activator.GetObject.
Is this possible?
Thanks!

Did you try using RemotingServices.Marshal? That allows you to register an already created object as a remote object.

Thanks for you answer. This is my code now:
<br />
tcpServerChannel = new TcpChannel(8080);<br />
<br />
ChannelServices.RegisterChannel(tcpServerChannel);<br />
<br />
RemotingConfiguration.RegisterWellKnownServiceType(<br />
typeof(IMyClass),<br />
"MyClass",<br />
WellKnownObjectMode.Singleton);<br />
<br />
myobject = new MyClass();<br />
<br />
myobject.UpdateServerData += new UpdateServerDataHandler(UpdateData);<br />
<br />
RemotingServices.Marshal(myobject, "tcp://localhost:8080/MyObject", typeof(IMyObject));<br />
As you see, I want to be triggered when the server data changes. However, the UpdateServerData of the server object is <undefined> when I use a breakpoint at the point it should throw the event.
Any ideas?

Could it be that you're coming from a VB background? 
First, C/C++/C# uses '==' to test for equality and '=' for assignment.
Secondly, the whole if clause has to be written in parenthesis.
if ((userName.ToString() == "myname") && (userPwd.ToString() == "mypassword")) Btw. please tell me you don't plan to use this code outside your test project...

If userName and userPwd are TextBox controls (as opposed to string variables), you have to use the Text property.
if(userName.Text == "myusername" && userPwd.Text == "mypassword") Also note the equality operator (==) instead of the assignment operator (=).
And yes, please tell us this is not real production code!

Hello,
I am developing a program to access mails from a Exchange server 2003 Mailbox. For this I am using MSXML 2.6, XMLHTTP and WebDav protocol's PROPFIND method.
Till Now I created one Sample Console Application to execute these tasks (basically Exe). But when I try to implement the same logic in Web Application I am getting an Error. See the screen shot below.
I tried the same with a Console Application/Windows Application, both are working fine and able to access Exchange Server 2003. I am able to Read/Send Emails from Exchange Server and also able to Change Mail Message Status as Read.
Problem is when I create Class library (dll) or a Web Application to use the same code I am getting the error and I am unable to access Exchange Server 2003. I tried with different versions of MSXML but no use.
Any help regarding this would be very helpful.
Thanks & Regards,
Srinivas Muvvala.
