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?

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[^].

Exception When Accessing Process.StartTime, Exc:"Access is Denied"

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 />
                                 // following statement causing exception<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"

What process are you trying to get to ? I guess access is denied.

Hi there,

Thanx for reply Graus.

This process is causing the exception.

I m running this code in Vs 2005, While same code is running succesfully in VS 2003. I can't understand this weird behaviour.

Here is complete code of my method, u can test it on VS03.

                foreach (Process p in processes)<br />
                {<br />
<br />
                    Console.Write("\nProcessName: " + p.ProcessName);<br />
                    Console.Write("\tID: " + p.Id.ToString());<br />
                    Console.Write("\tStartTime: " + p.StartTime.ToShortTimeString());<br />

If you are getting the error on Vista or Windows 7 it can be caused by UAC. See this blog post for a workaround: Bugs in System.Diagnostics.Process Class

Remote sensing image(b&W - captured by satellite), segmentation of the image is separeted by roads, trees, buildings, water levles done in C#.net or vb.net. Any possible ways to implement this.

Hi all,

Wanna create a new website with 3/n tier.I want to keep all the business logic and DAL in different projects, in the same solution.

Please tell me the most efficient way to do this
should I add a new windows project to solution and start coding at the same place or

create an individual project and after successfully building it add it to my solution

or any other efficient way is there other than these two. Please give me your suggestions.

With Thanks & Regards

Wow. I'm not sure if you're serious. You can do whatever you like, although it stands to reason that the process with the least steps is to create the project within the existing solution, you'll lose valuable micro seconds if you do it the other way.

Well, I'm not sure how you think it could affect anything. Code is code. The way it builds won't change by how it was added to a solution, in fact, the two methods you suggest, each create exactly the same thing, a project that gets built within the context of a solution.

As there is no interface needed for other two layers BLL and DAL so you should make them class libraries.

Create a new web application project and add your other two class libraries in the same solution. this will help u out when u start coding.

Hello Friends,
I am developing an barcode application and i am facing a problem that i am unable to arrange multiple prints on a single page it only print one barcode on one page another barcode on another page. So how can i arrange multiple barcode print on single page.

Re: How to arrange print?

Christian Graus3-Mar-08 17:21

You need to write your printing code so it draws the barcode more than once on the page. Your print code just calls your normal paint code, so you need to change how that works during a print.
