I am wondering if it is possbile to show multiple line for this param name "searchPattern" in the ///summary section. (Documentation explaining about the method and its parameters.
I mean to show as this in 2 lines.
For all files, use "*.*".
For hex files only, use "*.hex"
Instead of on one line.
For all files, use "*.*". For hex files only, use "*.hex"
<code snippet below>
/// <summary>
/// Gets the list of filenames in a certain directory path.
/// </summary>
/// <param name="path">Directory path</param>
/// <param name="searchPattern">For all files, use "*.*". For hex files only, use "*.hex"</param>
/// <returns> List of filenames in a directory path.
/// </returns>
public string[] GetFilenamesInDirectory(string path, string searchPattern)
{
....
}
|
|
|
|
|
Try:
/// <param name="searchPattern">For all files, use "*.*".<br/>For hex files only, use "*.hex"</param>
Modified: just realised you might have meant like this:
/// <param name="searchPattern">
/// For all files, use "*.*".
/// For hex files only, use "*.hex"
///</param>

Try this:
There are a set of pre-defined tags that one can use why doing XML style comments. Place a " < " and VS will display them to you."No matter how many fish in the sea; it will be so empty without me." - From song "Without me" by Eminem

This is what I did and it did work!
/// <param name="searchPattern">For all files, use "*.*".<para/> For hex files only, use "*.hex"</param>
Thanks for the help!

Hi,
I cant figure out how to switch my customcontrols when clicking on a menubar-button.
I have a MainWindow containing the following XAML:
<DockPanel x:Name="MainWindow">
<Menu Name="dropDownMenu"
DockPanel.Dock="Top">
<MenuItem Name="dropDownPage1" Header="File">
<MenuItem Header="Page1" Click="dropDown_Page1"/>
</MenuItem>
<MenuItem Name="dropDownPage2" Header="File">
<MenuItem Header="Page2" Click="dropDown_Page2"/>
</MenuItem>
</Menu>
<Grid Name="gridMainContent" DockPanel.Dock="Top">
<TextBlock>placeholder main content</TextBlock>
</Grid>
<Grid Name="gridStatusBar" DockPanel.Dock="Bottom">
<TextBlock>placeholder statusbar</TextBlock>
</Grid>
</DockPanel>
The task is when clicking on one menubutton i.e. "dropDown_Page1", changing the content of the grid "gridMainContent".
Is there a way to place customcontrols into a grid without code in any *.cs File ? It would be wonderfull if somebody could help me on this.
Cause I´m new to WPF, I welcome you to show me other ways of doing this!
Thx! PingOfDeath

Hi, I wrote some code for two modems: one, must send some string and another must answer the call and receive the string. My receiver modem is a D-Link voice-modem which has COM port, and the sender modem is a NetForce usb2.0 data-modem. Two modems are connected to two different computers and each one has a phone line. I first run the receiver's code and then the sender's code. Here's the code for each of them and log files:
The receiver modem's code:
SerialPort sp = new SerialPort("COM1");
private void Form1_Load(object sender, EventArgs e)
{
sp.NewLine = "\r\n";
sp.Parity = Parity.None;
sp.DataBits = 8;
sp.StopBits = StopBits.One;
sp.DtrEnable = true;
sp.WriteBufferSize = 1024;
sp.Open();
sp.WriteLine("ATE0");
sp.BaseStream.Flush();
sp.DataReceived += new System.IO.Ports.SerialDataReceivedEventHandler(sp_DataReceived);
}
void sp_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
{
string str;
str = sp.ReadLine();
if (str == "RING")
{
sp.WriteLine("ATA");
sp.BaseStream.Flush();
}
System.IO.File.AppendAllText("c:\\log_receiver.txt", str + "\r\n");
}
private void Form1_FormClosed(object sender, FormClosedEventArgs e)
{
sp.Close();
}
and its log file(log_receiver.txt):
OK
RING
CONNECT 9600
And sender's code:
SerialPort sp = new SerialPort("COM8");
private void Form1_Load(object sender, EventArgs e)
{
sp.NewLine = "\r\n";
sp.Parity = Parity.None;
sp.DataBits = 8;
sp.StopBits = StopBits.One;
sp.DtrEnable = true;
sp.WriteBufferSize = 1024;
sp.Open();
sp.WriteLine("ATE0");
sp.WriteLine("ATDT6632");
sp.BaseStream.Flush();
sp.WriteLine("My string to be sent");
sp.BaseStream.Flush();
sp.DataReceived += new System.IO.Ports.SerialDataReceivedEventHandler(sp_DataReceived);
}
void sp_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
{
string str;
str = sp.ReadLine();
File.AppendAllText("C:\\log_sender.txt", str + "\r\n");
}
private void Form1_FormClosed(object sender, FormClosedEventArgs e)
{
sp.Close();
}
and the sender's log file(log_sender.txt);
ATE0
OK
NO CARRIER
I have read all the commands of the Hayes AT commands, but there were no tutorial about how to use the commands(I know that using commands may differ in some modems). I wanted to know that where's the problem of my code and does anyone have an idea about using AT commands in order to send and receive data between modems?

| The "NO CARRIER" message indicates that there is no connection to the telephone line. Maybe you need to check your circuitry, or whether the receiver hangs up after getting the "RING" message. txtspeak is the realm of 9 year old children, not developers. Christian Graus

so, why one of the modems returns CONNECT 9600 message?!

Sorry, no idea, you need to check that your program is not causing a hang-up, or that there is no problem in the modem.txtspeak is the realm of 9 year old children, not developers. Christian Graus

I created a custom timer class (MyTimer). The class is basicaly just a wrapper that internaly uses System.Threading.Timer. Class MyTimer will be used in a windows service app. Since the Timer class signals it events on the background thread, I am using Dispatcher.Invoke to marshal the requests to the current thread. Below is the event handler for the internaly used System.Threading.Timer.
private void timer_Elapsed(object state)
{
if (Dispatcher.CurrentDispatcher != _dispatcher)
{
_dispatcher.Invoke(
new System.Threading.ThreadStart(delegate
{
onTick();
}), DispatcherPriority.Send);
}
else
{
onTick();
}
}
private void onTick()
{
if (Tick != null)
{
Tick(this, new EventArgs());
}
}
The problem is that in some casses the _dispatcher.Thread is in stopped or WaitSleepJoin state, and the onTick() method doesn't execute. Does anybody has a solution to this problem? Any ideas will be appreciated.

Is there a tool that would help me examine the application domains in a running process that hosts the .NET runtime (BizTalk for instance)? Or the DLL's loaded by the said process?
|
|
|
|
|
In order to get the Dlls loaded by a process, you can make use of Process.Modules property. Not sure about getting the list of AppDomains in a process. In case you know the AppDomain, AppDomain.GetAssemblies method would do same for you."No matter how many fish in the sea; it will be so empty without me." - From song "Without me" by Eminem
|
|
|
|
|
Thank you for your answer. I will start with that, that should be enough.
I wanted to do this because you can instruct BizTalk to load specific assemblies into named domains and not to unload those domains when idle.
|

|
|
|
You can also use the Fusion Log Viewer, it's installed with most visual studio installs, if not it is easily downloaded from Microsoft Downloads. Open up a visual studio command prompt, and type FUSLOGVW. have this open whily you run your process, and it will log all the assembly binds that occur.

Hi i am trying to write a tree view control however have come accross difficulty in drawing the vertical lines.
The bellow method currently works by fining the cumulative height of the last branch it was in and then calls AmountToDeduct(nodes[i].Nodes) to reduce this to the correct height for the next line.
However this is very slow. Does anyone know a way i can simply not add nodeheight to the newLineFinishPoint if it is not needed apposed to taking away from the total heigh.
private Point PositionNodes(List<Node> nodes, Point point)
{
Point newStartPoint = new Point();
Point newFinishPoint = new Point();
newStartPoint = point;
int nodeHeight = nodes[0].Size.Height;
for(int i = 0; i < nodes.Count; i++)
{
nodes[i].Location = point;
point.Y += nodeHeight;
if (nodes[i].Nodes.Count > 0 && nodes[i].Expanded)
{
point.Y = PositionNodes(nodes[i].Nodes, new Point(point.X + m_xIndentation, point.Y)).Y;
}
newFinishPoint = point;
newFinishPoint.Y -= (int)(nodes[0].Size.Height * 0.5);
if (nodes.Count == 1 && nodes[i].Expanded)
{
newFinishPoint.Y -= AmountToDeduct(nodes[i].Nodes);
}
m_linePoints.Add(newStartPoint);
m_linePoints.Add(newFinishPoint);
}
return point;
}
Thanks in advance

Here is one way:
string[] lines = new string[5];
using (StreamReader sr = new StreamReader(@"c:\XXTemp\data.txt"))
{
for (int i = 0; i < 5; i++)
{
if (!sr.EndOfStream)
{
lines[i] = sr.ReadLine();
}
}
}

try
{
StreamReader objStream;
string myfile = Request.QueryString["txtreader"] + ".txt";
string reading = Server.MapPath(myfile);
string[] lines = new string[5];
using (objStream = new StreamReader(reading))
for (int i = 0; i < 5; i++)
{
if (!objStream.EndOfStream)
{
lines[i] = objStream.ReadLine();
lblDispaly.Text = lines[i];
}
}
objStream.Close();
