Hi,
you can use :
listView1.Items[i].SubItems[0].BackColor = System.Drawing.Color.Red;
And this must be false, else the total area of the line is in the same color.
listView1.FullRowSelect = false;

Hi,
Just looking for some advice as I think my current working solution is probably wrong. I've written a small video player in C# using ffmpeg as the decoder and a thread to process and display the footage. However, as I try and further the player's development the thread idea seems more difficult to control. My main window initialises the video footage but plays its output in a seperate thread to a seperate window. To pause the video I suspend and resume the thread, this works fine. To stop the video I abort the thread and kill the seperate window, I can then initialise another video and then play it fine. If, however the video plays to the end I can't restart the player as the previous thread doesn't seem to have terminated properly. Is it possible to control threads where they can be stopped and restarted.
Thanks in advance.

I imagine so. I have never implemented an approach that aborts threads since virtually all the documentation you read warns against aborting threads. You should use thread communications techniques to control the operations of the thread internally. The result is that the code executing in the thread has an alternate path that causes the thread procedure to return which ends the thread in a proper controlled fashion.
public static void ThreadProcedure(...)
{
while ( IShouldContinuePlayingRecording() )
PlayRecording();
}
So to cause a thread to end looks like this:
1) parent thread communicates with child thread telling it to end
2) child thread receives the message and alters it's flow of control resulting in the thread procedure returning.
is that what you were asking?

This should provide some clue as to what's going on. First, you should allow the thread to exit if playback completes (I can infer that you're doing this, I'm just making sure). While you could probably manage to keep the thread alive and consume new playback requests, it is probably much easier to simply let the thread exit and create a new thread when you want to start a new playback.
With that in mind, if your thread is using any unmanaged resources that it doesn't release when the thread exits, the thread will hang when it attempts to exit. I've run into this on multiple occasions. If your thread doesn't seem to be terminating properly, I would look at the resources you're using in that thread and make sure any objects you use are properly Dispose()'d if their documentation says to do so.

Hi All,
I am working on the project using c# 2.0. I need to get the contents of window.status bar and save into string variable. Please help if you can.
Thanks in advance.

What window are you talking about? The web browser's status bar?
|
|
|
|
|
yes web browser window. I am using the following code but doesn't work.
string result = LPBrowser.Document.Window.StatusBarText;
Thanks.

I'm sorry, I still don't understand. Is LPBrowser something in ASP.NET? Or is this a Windows Forms web browser control?
If it's a Windows Forms web browser, have you looked at browser.StatusText property?
If this is something in ASP.NET, I recommend you post your question in the ASP.NET forum.

Hi,
LPBrowser is just the name I gave to browser control. Currently I am using following code but for some reason these codes not working,
string result;
string someVar;
some Var = LPBrowser.StatusBarText //This line doesn't work
result = LPBrowser.StatusText; ///This line doesn't work

Hi everyone.
I have got some VB6 code i need to translate to C#, but i really cant understand the VB code.
The program is something that communicates with a serial dervice.
I do not know how much of the code I need to get translated, so it is possible that I will post more code later.
Until now i've got this code:
Private Sub Command1_Click()
Dim CheckSum As Byte, x, Tid
MSComm1.Settings = "1200,N,8,1"
Buffer = "GET" + vbCr
CheckAndSum Buffer ' add Checksum and Length of string
Buffer = Buffer + SumStr
'For x = 1 To Len(Buffer)
' Tid = Timer
' Do
' DoEvents
' Loop Until (Timer - Tid > 0.01)
' MSComm1.Output = Mid(Buffer, x, 1)
'Next x
MSComm1.Output = Buffer
End Sub
This should write some code to the Serial Port.
I have already got the code for creating the checksum.
When my device receives the GET command with vbCr (Carridge return), the checksum and the string Length, it should return 10 characters an example could be c=02345"Carrigde return"Checksum1Checksum2
I do not think you need more code that i pasted to do this. But I am not sure..
It would really be a great help if you could help me with this..

I already had looked at MSDN.. I have tried make some code.. But no matter what i do it doesn't seem to work..

A few questions...
Which serial port? How do you know this does not work? Where is code to listen for the result your program is expecting? What is the specification of the device that needs this input? Maybe the port parameters do not match up?

Does this article[^] help? It shows how to create an XSD file from a class.
Also, there is an XSD.exe utility in the .NEt framework SDK that may help you out.

Hi all,
I'm trying to show a tooltip for a button.
I have a StopWatch,
the purpose is to show the elapsed Time into the tooltip string. and to get the refreshed value each time the mouse is under the button
I'm doing like that
this.toolTip1.SetToolTip(button1, Stopwatch.Elapsed.ToString());
but the tooltip shown have always the same value
How can I update this value ?
Thanks for help

I think you may have to hide the tool tip and reshow it again.
That, or use a custom tooltip that lets you set the text while it's visible.

Hi,
I have a problem to understand one thing concerning structs.
It is said that structs are value types. But what happens when a Reference Type member is defined for a struct? Because it is a member of a struct does it behave like a value type -meaning both its value and reference address are stroed in the stack together?
Thanks!
