as far as i know you cannot retrieve additional information about serial ports with the System.IO.Ports classes, but you can use WMI to get the information you need.
check out the win32_serialport class.

Is there any method to keep the assemblies in separate folder rather than putting it in the same folder where program is executed ? I am trying to deploy a windows application with dlls kept in a sub directory where application is installed. But it's throwing error which said "Assembly could not be loaded". Is there any other way to do this ?
|

AFAIK, The answer is NO. You have to keep the assembles either in GAC or in the same folder along with the executable.
There is a work around. By using System.Reflection.Assembly.LoadFile() or
System.Reflection.Assembly.LoadFrom() methods, you can load the assemblies from a different folder; but you may have to change the design and the application will suffer a little(regarding performance).

After replying to your post, I did some googling and came across this article. It is possible to keep the assemblies in a sub folder. You have to do the following.
1. Keep a config file (YourExe.exe.config)
2. Keep the following configuration settings
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<probing privatePath="NewFolder"/>
</assemblyBinding>
</runtime>
</configuration>

Then why ask in the C# forum?

Hi,
I created a hash table with 3 elements.
hashtbl.Add(1, "aaa");
hashtbl.Add(2, "bbb");
hashtbl.Add(3, "ccc");
When I'm trying to modify the hash table as following,
hashtbl[2] ="xxx";
hashtable's length increased by 1.
After the above statement, hashtbl looks as following.
hashtbl[2, "xxx"]
hashtbl[1, "aaa"]
hashtbl[2, "bbb"]
hashtbl[3, "ccc"]
How can I restrict the hash table to add a new element with the same index, 2? I would like to get hashtable as below after the modification.
hashtbl[1, "aaa"]
hashtbl[2, "xxx"]
hashtbl[3, "ccc"]
Thanks in advance..

Is this using the built-in HashTable class? I would recommend using Dictionary<int, string>[^] instead. Your problem may have been due to some weirdness while boxing.

Thank you Vega02. Its worked and come to know about Dictionary class.

That is exactly the reason for the problem. The HashTable class uses reference types as identifiers, so if you try to use value types as identifiers, they are boxed first.
Each time you box the value 2, it becomes a new object on the heap, containing the value. As they are separate objects, they have different hash codes.
Despite everything, the person most likely to be fooling you next is yourself.

Shouldn't the hash codes be the same, since they represent the same underlying value? It doesn't matter that they're boxed value types. They don't have reference equality, but they still have value equality, hence they should have the same hash code.

Vega02 wrote: Shouldn't the hash codes be the same, since they represent the same underlying value?
No, the values are boxed in a type Object, and the hash code of the Object is not based on the boxed value.
The GetHashCode method of the Object type is not suitable for use as key in a hash table. From the documentation:
"the default implementation of this method must not be used as a unique object identifier for hashing purposes"
MSDN Library: Object.GetHashCode method[^]
Despite everything, the person most likely to be fooling you next is yourself.

hi
As you told that you use msaccess database then no requirement to include database seprately. to deploy your project do the following..
1. File -> New Project -> Choose Other Project -> then Setup project
2. In the application folder add all the files available into your bin folder including the database file also.

Hello,
I'm trying to make connection between a C# client to a C++ server.
Since I'm new at C/S I just downloaded sample programs, and tested them.
I downloaded the C++ server (and client) from:
http://www.codeproject.com/KB/IP/client_server_socket.aspx
The communication succeeded.
I also downloaded C# C/S from:
http://www.codeproject.com/KB/IP/tcpclientserver.aspx
It also worked.
But when I tried to make a connection from the C# client to the C++ server it didn't work (later on I also tried other versions of servers and clients in both languages – none worked).
What I see is that the client succeeded to connect to the server, but it didn’t succeed to send anything to the server, and the server stayed blocked waiting for the client's message (I encountered a version in which the server did get a message, i.e. was released from the blocking condition, but the message was empty).
BTW, when I changed the code such that only the server sends a message to the client - everything worked.
I don't know what problem to look for, nor if there is any known problems in this scenario.
I will really appreciate any help or idea what to do.
Thanks,
Itzik

Probably you need to examine what the code does in both instances to make sure they are communicating on the same port, and expecting to send/recieve data in the same format.

Thanks for your reply.
I checked it over and over ):
The ports are OK (The server does get the connection from the client).
Regarding the formats: the server is not released from the blocking situation of waiting for data (receive). So, is it possible that C# sends different format for simple strings (UTF, or something else) than C++, and is this format change can cause that the 'receive' function stays blocked?

Hi,
I am using Crystal Report Designer in my C# project. and kindly let me know, how may I create PDF file on button press?
"Is there any ready made samples about my said subject?"
Thank you in advance

Most PDF librarys probably come with a sample that does what you want. You can't create a PDF without a PDF library.

Adding to Christian's reply, you need to use a library that would enable you to create PDF files on the fly. You may try iTextSharp[^].

Hi there,
I have to get processes info for a system but I m having an Exception "Access is denied" in this code,
<br />
try<br />
{<br />
processes = Process.GetProcesses(mcName);<br />
int nThreadsCount = 0;<br />
foreach (Process p in processes)<br />
{<br />
<br />
string[] prcDetails = new string[]{p.ProcessName,<br />
p.Id.ToString(),<br />
p.StartTime.ToShortTimeString(),<br />
p.TotalProcessorTime.Duration().Hours.ToString()+":"+p.TotalProcessorTime.Duration().Minutes.ToString()+":"+p.TotalProcessorTime.Duration().Seconds.ToString(),<br />
p.Threads.Count.ToString(),<br />
p.HandleCount.ToString()};<br />
<br />
nThreadsCount += p.Threads.Count;<br />
<br />
}<br />
}<br />
catch (Exception ex)<br />
{<br />
MessageBox.Show(ex.Message); <br />
}
When I commented the statement
p.StartTime.ToShortTimeString(),
then next statement which is also getting-time-related property
p.TotalProcessorTime.Duration().Hours.ToString()
is also causing same exception.
Here is the Sysem Trace:
" at System.Diagnostics.ProcessManager.OpenProcess(Int32 processId, Int32 access, Boolean throwIfExited)\r\n at System.Diagnostics.Process.GetProcessHandle(Int32 access, Boolean throwIfExited)\r\n at System.Diagnostics.Process.GetProcessTimes()\r\n at System.Diagnostics.Process.get_StartTime()\r\n at CustomizedTaskManager.frmmain.LoadAllProcessesOnStartup() in E:\\MyProjects\\Programing\\C#\\Task Manager\\CustomizedTaskManager\\CustomizedTaskManager\\Form1.cs:line 100"
