we are doing a project for streaming video over the network in c#.net.
it is a client-server based model. the server sends bytestream to the client and stores it in the memory(memorystream). we are planning to use the directshow functions to play the video.
the renderfile function plays videos from a location in the hard drive. what we want is to play the video data streamed over the network directly from the memory of the client computer. this is really important, so please help us
thank you in advance.
are there any alternatives to this?

You can use the MailMessage Object to fill the from, to, subject, address. and then use the smtpclient object to set the SMTP server to be used and to send the mail Message.

Hi…
In my application…I am trying to add data received on comport in a rich text box. Rich text box is on second form & my SerialPort.datareceived event is on first form. Here is my sample code…
form2 f2 = new form2();
Serialport.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived);
private void port_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
ReceivedData = comport.ReadExisting();
f2.Controls[0].Invoke(new EventHandler(delegate{f2.Controls[0].AppendTextReceivedData);}));
}
But I am getting error on the staement-
f2.Controls[0].AppendText(ReceivedData);
Error is - ('System.Windows.Forms.Control' does not contain a definition for 'AppendText')
I have only one rich textbox control on form2…
What is the problem…why I am unable to access "Appendext" method for the rich text box on ‘form2’ from 'form1'
Thanks,
Vinay

test two point:
1, is the RichTextBox in f2 accessable? use public test it again.
2, f2.Controls[0] is a control. if you can sure it is a RichTextBox, then test these
<br />
RichTextBox r = f2.Controls[0] as RichTextBox;<br />
if (r != null)<br />
{<br />
}
hoping this help.

I tried with u told...
But my richtextbox in f2 is not accessable from f1...Although declared it as public.
& RichTextBox's TabIndex is 0...
Thanks for your reply,
Vinay

Sorry 1 braket was missing...
Statement should me like this...
f2.Controls[0].Invoke(new EventHandler(delegate{f2.Controls[0].AppendText(ReceivedData);}));
& i am getting error on this staement for AppendText method...
Thanks,
Vinay

Hi!
If you read the error message (that's usually the prerequisite for finding out what's wrong ) you'll see that the compiler tells you that Control doesn't have a method AppendText.
The Controls collection holds Controls, not RichTextBoxes, so the error message can be explained easily.
Use ((RichTextBox)f2.Controls[0]).AppendText(...) to get rid of the compiler error.
But keep in mind that the code above is bad style. It's easy to add another control to the form and suddenly your RichTextBox isn't Controls[0] anymore - an InvalidCastException will result.
I think it's better to explicitely expose the RichTextBox as a property of f2.

Hi...
i tried your suggestion
((RichTextBox)f2.Controls[0]).AppendText(...)
but its didnt worked.
Can u tell me what you want to say exactly with-
"explicitely expose the RichTextBox as a property of f2."
Thanks,
Vinay
|
|

|

Modify your class form2 to contain
public RichTextBox MyRichTextBox
{
get {
return richTextBox1;
}
}and use f2.MyRichTextBox instead of f2.Controls[0].
And by the way "its didnt worked" is not helpful at all - if you don't tell us what the problem/error message is exactly we cannot help you.

<br />
public Form f1;<br />
<br />
f1 = new ChildForm();<br />
f1.MdiParent = this;<br />

{<br />
string ReceivedData = comport.ReadExisting();<br />
<br />
ReceiveLog(LogMsgType.Incoming, ReceivedData);<br />
<br />
if(f1.Controls[0].InvokeRequired)<br />

Once again: Please read the error messages you get and try to understand them.
If you don't understand them, post them here so that we can help you!
With the code snipplet you posted I think the problem could be that you declared f1 as Form but in fact it's an instance of ChildForm.
The class ChildForm does have a public RichTextBox named MyRichTextBox, the class Form doesn't.
So to get your code to work you should change public Form f1; to public ChildForm f1; and your DataReceived event handler should read
string ReceivedData = comport.ReadExisting();
ReceiveLog(LogMsgType.Incoming, ReceivedData);
if(f1.MyRichTextBox.InvokeRequired)
{
this.Invoke(new EventHandler(delegate
{ f1.MyRichTextBox.AppendText(ReceivedData); }
));
} else {
f1.MyRichTextBox.AppendText(ReceivedData);
}

Hi All,
I have a compeleted project that uses ms access database and some images and crystal reports, how can I make an installation file (Setup file). concerning the directory path for db file. Also, in crystal reports I had to specify the db file path in side the code. I tried the built in component in VS2005 but I couldn't.
Very Urgent, Could any one help
|
|

You may set the db connection of Crystal Reports in code.
I used CrystalReport before, but I don't have these sample code at home.
Please get this from MSDN.
hoping this help.

I am replying for what i got to know about your unclear statements, i guess your problem is that when u install some application, then it doesnt find it resources like images,icons, bitmaps after installation, well mate.. for that while making setup file, Include them in a wizard and then include this line
AppDomain.CurrentDomain.BaseDirectory
it will refer to the current installation directry or from where the exe is being run 
enjoy !
if u face any problem do contact me

Thank realin for your reply,
This is a part of my code in the report viewer:
-----------------------------------------
int slach = Application.ExecutablePath.LastIndexOf('\\');
string dbLocation = Application.ExecutablePath.Substring(0, slach) + "\\Database\\hall.mdb";
ReportOkRes1.DataSourceConnections[0].SetConnection(dbLocation, dbLocation, false);
-----------------------------------------
It works fine in VS2005 but when I do the Setup project, and do the installation the application didn't work. I am sure that the problem is in reading from the db file "It does not find it".

Im a begining C# programmer and was hoping you guys could help me. Im working on my first real project and I am a little confused on how exactly to set it
up. I've read so many articles on this, but they all seem to be saying different things. Here is a psuedo code example of my current setup:
class EmployeeDA<br />
{<br />
public void Insert(Employee emp)<br />
{<br />
}<br />
}<br />
<br />
class Employee<br />
{<br />
private int id;<br />
private string name;<br />
private EmployeeDA = new EmployeeDA();<br />
<br />
public void Insert()<br />
{<br />
EmployeeDA.Insert(this);<br />
}<br />
}<br />
<br />
class Employees : List<Employee><br />
{<br />
public void AddEmployeesToTable()<br />
{<br />
foreach(Employee emp in this)<br />
emp.Insert;<br />
}<br />
}
Is this correct? I know there are many different ways to do it, so maybe "correct" isnt the right word. I guess what I want to know is if there is a "better" way of doing it. Are there any glaring issues with the way I am doing it currently?
Thanks
