No, just creates another extra subfolder.
I think you're mixing up the terms "solution" and "project". You'd have a single solution, with multiple projects - and that's what most of us will have.

That's fine. My doubt come from the wording used in VS: "New Solution Folder", so I thought I'm creating really a new solution, but it is rally a "New Folder of Projects".
Is it right my note? (I'm checking if I correctly understand)

A solution folder is just a folder at the solution level that you can use to organise things in. They could be projects or they could be things such as common DLLs that you want to refer to across the solution.

Thanks,
I note that
using "New Solution Folder" you can add in project and can be used only at higher level than project. The folder is not really created in the HD. The name of solution folder can not use special characters such as "#" (strange... If I add a Folder I can...)
using "New Folder" can be used inside a project and can contain files. The directory is really created in the HD and you can use special character such as "#"
Obviously  I needed a mixed solution.. I need to use special character and I should contain project.. Not lucky...

Hi C# Guys,
is there way to find the filename that relates to network port?
so, I can enumerate the network ports, but is there a way to find the file(s) that is being access that relates to that network activity?
many thanks,
P

If you're talking about something like a \dev\... name like you find in Linux, there's no such thing in Windows.
If your'e talking about a file being transfered over a TCP/IP connection, no. The filename is not attached to the port in any way at all.
|
|
|
|
|
is there not a chain of activity you could follow?
port -> service -> thread -> file ?
|
|
|
|
|
Not every port has activity, not every port is for files. Here's[^] a list of port-numbers, and what they do.
|
|
|
|
|
Well that changes the question a bit...
No, there is no chain like that, but you can find all the ports that are being listened to and get the process ids (PIDs) of the process that is listening on that port. You then need to enumerate the entire Windows handle table, filter out just the files that are open, get the PIDs of the owners of those handles, then match them up with the PIDs you got from the listeners pass.
This is a rather time consuming process and if you wanted to get a constant "real-time" update, you'd be using a ton of processing power because of the constant polling you'd have to do.
Oh, and all this requires admin priv's.

I'm working on the 3 motor drivers that has their own ComPort on the computer. (yes 3 Serial Ports on the back of computer).
In the past, I've been using the do-while loops to do the Serial.Readline() to monitor the driver's response to the command. That really slows the processing and usually hangs the application very often.
I've modified the code to add the DataReceived event for each port. I've been sending lots of drivers' configuration (and gets the response back from the driver as echo as well.)
After sending all of the configuration, the other process begins.
The problem is that the drivers didn't finish sending back all of the responses before the new process begin. This caused the new process commands to be messup with communication.
Question is... how do I check if the configuration responses are completed before running the next process?
Your help would be greatly appreciated. Thanks!

There are a couple of ways to handle this, but it depends on how you want to work it.
The simplest solution is to set up a thread to handle each com port - that way they can use ReadLine all they want, and you don't have to worry about them hanging the UI thread or about data synchronisation. You then have to communicate between the UI and the threads - and I have no idea how complex that is for you because I don't know what you app is actually doing.
The other is to use the DataRecieved Event in the UI thread as you seem to be doing - but that has to be handled differently, because the data is not received in the form of lines - it arrives character by character (or a couple of characters at a time if the processor is busy) so you have to buffer and examine the data a bit more carefully.
Exactly which way you should go, I don't know - but without seeing any relevant code fragments, I can't tell what your code is doing at the moment, so I can't make any concrete suggestions.

Welcome to the C#-forum; I'm a WinForms-programmer, you'd probably have gotten a better response in the ASP-forum.
Doesn't ASP.NET give a bit more "detailed" error, than the mystical catch-all? I'd guess it's the version of JET/MDAC (the Microsoft Access drivers), or the read/write permission for the internet-user on that particular folder.
I suggest you open the database in Access, and find the "Upgrade to Sql Server" button. It'll convert all tables to Sql Server-format. Access isn't really designed to handle many requests from different users, and there's no file-level read/write permission to worry about once you're using Sql Server. There's a free version available, called Sql Express.
Further, I'd throw in some logging, wrap the con.open() in a try..except, and log any exceptions.
Good luck

This problem has been resolved.
It turned out that there was a slight difference between the code that worked and the one that did not. The Internal Server Error 500 was being casused by the following issue.
Problem: There are GridView features that are supported by the ASP.NET 3.5 version on my laptop, that was not supported by the version ASP.NET version 2.0 that the hosting server was using.
Remedy:
Remove the unsupported properties from the Gridview. They are the tags that have to do with <SortedAsceding..> or <SortedDescending…>. Then publish the file again.
CODE from the offending file.aspx
<asp:GridView runat="server" id="GridView1" AutoGenerateColumns="False" DataSourceID="DetailsFromDBDataSource" CellPadding="4" ForeColor="#333333" GridLines="None">
<AlternatingRowStyle BackColor="White" />
<Columns>
<asp:HyperLinkField DataTextField="ProductName" HeaderText="Product Name" NavigateUrl="hottea.aspx">
</asp:HyperLinkField>
<asp:BoundField DataField="CategoryID" HeaderText="CategoryID" SortExpression="CategoryID">
</asp:BoundField>
<asp:BoundField DataField="UnitPrice" HeaderText="UnitPrice" SortExpression="UnitPrice">
</asp:BoundField>
<asp:BoundField DataField="UnitsInStock" HeaderText="UnitsInStock" SortExpression="UnitsInStock">

I am using MEF in my application. My application have 4 parts(class library) and a main module , the main modules responsibility is to interact with the above said parts and delegates job to them.
I have coded all the interface and abstract base classes in a library called 'Common' and refer it to all the other dlls which have classes inherit from those base classes. I moved all the base class and interface definition to the 'Common' library so that i can add reference of that dll in my main program and all the base classes and interfaces are readily available.
Is this the right way to do it? What is the other option in MEF using which i can refer to the base classes in my main module without referring to a dll.
eg:- abstract class baseAbc and interface IAbc is defined in common.dll, Is it possible to refer baseAbc and IAbc in my main module without adding reference to Common.dll

I have a custom control called EditorSection which contains a Button control for the header and a RichTextBox control. I have another custom control called EditorContainer which can contain multiple EditorSection controls. In the EditorContainer I have a Button control for "Print All", which obviously should print all of the EditorSection controls' content.
I created a class called "PrintSection", which stores the title (header text) for each section as well as a string array for the "Lines" property of the RichTextBox in each EditorSection custom control. All is fine so far.
When I click "Print All" I would like to print each section's header title and then prints that section's content below it, which will sometimes span more than one page. This is where I have a problem. I'm not sure how to achieve multi-page printing with this setup.
Here is how I populate a List<printsection> object:
this._printSections = new List<PrintSection>();
foreach (Control child in sectionsPanel.Controls)
{
if (child is EditorSection)
{
PrintSection section = new PrintSection();
section.Name = ((EditorSection)child).SectionName;
section.Lines = ((EditorSection)child).GetLines();
this._printSections.Add(section);
}
}
The "GetLines()" method returns the "Lines" property for the RichTextBox in the EditorSection control, while "SectionName" is the section's header title.
Here is what I have tried so far with printing:
int sectionIndex = 0, lineIndex = 0;
void document_PrintPage(object sender, PrintPageEventArgs e)
{
Graphics g = e.Graphics;
Font font = new Font(SystemFonts.DefaultFont.FontFamily.Name, 9.5f);
Font headerFont = new System.Drawing.Font(font.FontFamily.Name, 12.0f, FontStyle.Bold);
float yPos = 0;
PrintSection section = this._printSections.ElementAt(sectionIndex);
{
g.DrawString(section.Name, headerFont, Brushes.SteelBlue, 0, yPos);
yPos += (g.MeasureString(section.Name, headerFont).Height + 4f);
g.DrawLine(Pens.LightSlateGray, 0, yPos, g.MeasureString(section.Name, headerFont).Width * 2, yPos);
yPos += (g.MeasureString(section.Name, headerFont).Height);
for (int l = lineIndex; l < section.Lines.Count(); l++)
{
string line = section.Lines[l];
g.DrawString(line, font, Brushes.Black, 0, yPos);
yPos += (g.MeasureString(line, font).Height);
lineIndex++;
}
yPos += 32f;
if (sectionIndex < (this._printSections.Count - 1))
{
sectionIndex++;
e.HasMorePages = true;
}
}
}
The "sectionIndex" variable holds the zero-based index of the section currently being printed. I am able to print each section on its own page, which is desirable. However, I would eventually like to allow for printing continuously without making a new page for each section, as an option to the user.
The problem I am facing is this. How do I print the section's lines on more than one page if it doesn't fit on one page? I have the "yPos" variable which is the current position on the y-axis for printing. I have tried "if (yPos > pageHeight) { e.HasMorePages = true; }" but it doesn't print the remaining lines on a new page.
What am I doing wrong?

One call to the PrintPage handler is responsible for printing a single page. So if you want to be able to split sections between pages, you need to save some state information which allows the second call to the method to pick up a section part way through (just as you're currently storing sectionIndex so the next run of the method knows where to start).
|
|
|
|
|
Right. I just didn't know what I was doing wrong because I tried something like that. However, I *did* figure it out. I had to add a "break;" statement:
for (int l = lineIndex; l < section.Lines.Count(); l++)
{
string line = section.Lines[l];
g.DrawString(line, font, Brushes.Black, 0, yPos);
yPos += (g.MeasureString(line, font).Height);
lineIndex++;
if (yPos > e.PageBounds.Height)
{
e.HasMorePages = true;
break;
}
}
Because without the "break;" it was continuing the "for" loop until all lines had been processed. The "break;" causes it to go to the end of the PrintPage handler with "HasMorePages" set to true, which would pick up where it left off. I'm not sure how I skipped over that to begin with but your response seemed to set off a light bulb in my head. Thanks!
