Hey Luc,
I tried \r and \n too with no luck then I was trying the string value and I tried Chr(13) as well with no luck.
I will try the binary thing tonight and see what bits I am getting

Has the textbox a multiline option?
|
|
|
|
|
No. I am only concatenating two string
like...
string strValue="abc" + ";" + "xyz";
|
|
|
|
|
I have had luck writing serial data from a PIC microcontroller to a textbox using the following code in C#:
private void serialPort1_DataReceived_1(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
{
txtToDisplay = serialPort1.ReadExisting();
DisplayText();
}
public void DisplayText()
{
if (txtIn.InvokeRequired)
{
this.BeginInvoke(new MethodInvoker(DisplayText));
}
else
{
txtIn.AppendText(txtToDisplay);
}
}
Also, I set the comm port parameters in the same place I open the port, rather than the receive event:
private void GetComPorts()
{
foreach (string s in SerialPort.GetPortNames() )
{
lbPort.Items.Add(s);
}
}
private void btnOpen_Click(object sender, EventArgs e)
{
this.lbPort.SelectedIndex = this.lbPort.TopIndex;
this.lbRate.SelectedIndex = this.lbRate.TopIndex;
this.lbProtocol.SelectedIndex = this.lbProtocol.TopIndex;
string crlf = Environment.NewLine;
serialPort1.BaudRate = Int32.Parse(lbRate.Text);
serialPort1.PortName = lbPort.Text;
serialPort1.Open();
if (serialPort1.IsOpen)
{
btnOpen.Enabled = false;
btnClose.Enabled = true;
txtIn.AppendText(string.Format("Port {0} opened successfully." + crlf, serialPort1.PortName));
}
}
Anyway, this seems to work in my situation. Also, my PIC code is using "\r\n" so I am actually sending a {10} and a {13} pair.
Hope this helps,
Adam

Hi Adam,
Thanks! I will try that at home and see how it works with my uC. I did not try sending a 10 and 13, that might be worth a try as well!

Hey Adam,
Looks like it was searching for a 10 and 13, but it wanted them as a 13, then a 10.
Thanks to everyone who was kind enough to respond and offer help to me. I'll probably have more questions as time goes on and now that I have a baseline I can start to implement the other good pieces of advice in this thread

Do you wite firmware on microcomputer? try to change 0x0d to (0x0a 0x0d)
|
|
|
|
|
Try looking for a linefeed (10) character instead. If it's coming from a Unix/Linux box then that's what will be sent.

Hi,
I am using something like this to get all my running processes:
Process[] processlist = Process.GetProcesses();
foreach(Process theprocess in processlist)
{
Console.WriteLine("Process: {0} ID: {1}", theprocess.ProcessName, theprocess.Id);
}
My problem is that I want to know the filename (EXE) of a process, and the pathname it was started from. For example, if there is a process Notepad.exe running, I want to determine in which folder that file actually resides, i.e. something like "C:\Windows\system32\notepad.exe". How can I get that information?
I already tried to get the member StartInfo. but it doesn't contain a link to the folder.
How can I do this?

Good one
My vote 5.
|
|

|

You can also use
theprocess.Modules[indexno].FileName
|
|
|
|
|
that is much more expensive and in no way any better than what qwertz already provided.

Yes, that's why I vote 5 for qwertz and during writing my answer I have mention you can also use and code works very well. I just try to give an alternate answer.

Not a Matter
some people Down vote or comment without testing code, which is not good in any corner.

We need to handle Exception in this case.

Yes, in both cases either you are using MainModules or Modules you need to handle exception..

Hi,
I have a .NET C# application that contains many different assemblies. My start up project contains all assemblies as references, so when I build the application all these assemblies are copied to output directory.
Is it possible to replace one of the assemblies at runtime, if it exist a new version of that assembly?
Best regards
Olof

Short answer: No
Shortish answer: If you get to it early enough (before any types (or types that reference the types) are instantiated that reference the dlls) you can overwrite them.
Long answer: If you need more than the above gives you like being able to swap the types after they have been used you need to create a seperate AppDomain and load the dlls into that. If they get updated you can destroy the AppDomain and create a new one with the new dlls.
It all depends on what you are trying to achieve.

One way would be to load the assemblies using Reflection. That way, if an assembly changes periodically, you will get the latest
|
|
|
|

Hi, a lot of the types declared in the assembly I want to update at runtime are used both in this assembly and in other assemblies. And since a lot of people are working in the project at the same time it's not easy to make a bigger reorganization of the source files.
