I was thinking of creating a simple, specialised task manager. It seems quite easy to use the Diagnostics.Process class to get processes memory and CPU usage.
But I also need to get GDI and USER objects per process. Is there any similar class for that or is it performance counters or WMI I need to look into?

Yes, you do need to use performance counters for this.

Hi Heath,
thanks for your answer. I did look into the performance objects in PerfMon (I have a XP Home WS at home and a Win2K WS at work) and could not find any counters for the process object. Actually I could not find any counter for this. I have looked with exctrlst.exe and could not find any disabled counters.
So I have to ask if you can point me in the right direction on how to proceed:
1. Do I have to do something to add more counters to the process object (or they might just not are available in WS PerfMon).
2. Is there any other performance object I should look into (but I still want the count per process as in the Task manager).

If you can't find performance counters that suit your needs, you'll need to P/Invoke native APIs when appropriate, like GetPerformanceInfo or GetProcessMemoryInfo, both defined in psapi.dll on XP and newer. I recommend reading the native performance monitoring and Processes sections of the Platform SDK at http://msdn.microsoft.com/library[^]. The .NET BCL by no means provides a full set of diagnostic APIs for issues like this.

Through googling I later found that the easiest way was to use the GetGuiResources method in User32.dll. This provides the GDI and USER objects counters for each process.

Hello,
Is there anyone can help on how to access the windows (oulook) address book with the standard dialog. I need to get back name, company, phone number and fax number.
Thanks

In fact, the address book dialog I want to display is this used by Outlook when you click on "TO" button when you send an email. With this dialog you have access to your exchange address book and your personal adress book...

hi there !
i am doing a chat app with c#. i have used tcpclient and listener classes to send data across. recently i have encrypted
the data iam sending back and forth with rjindael encryption algorithm. when i did this iam losing some characters on the receiving end. it's sort of truncation. on both the server side and client i perform an asynchronous read with a buffersize of 5120. the sendbuffersize and receivebuffersize for the tcpclient are default which is 8192 bytes.
please tell me what is happening here and guide me.
thanks.

|
|
|
Have you tried calling Flush() on the encryption provider and/or the TcpClient stream after each write?

Hi reinux !
i am calling flush() after each call to write. thats already in place.
any more possiblities.
thanks.

Are you using a language with something other than 1 byte characters? You might be counting characters wrong. For example, say you're working with Japanese transmissions (2 bytes per character). Say there are 50 characters -- that's 100 bytes. But if you count characters rather than bytes, and you send only 50 bytes worth, you'll only get the first 25 characters across.
It's a rare mistake in C#, but it can still happen.
Hope this helps.

hey reinux !
thanks for that info man. i misunderstood my own problem. fixed it.
tahnks for your time. will post any questions i have in future on codeproject.
that was informative.

Hi,(new to programming)
I want to read xml data into an DataTable, but from what I've read you have to load it into a DataSet. Anyway, I was wondering if it was possible to end up with just a DataTable in the end with NO reference to the original DataSet? My attempt below still causes the error "DataTable belongs to another DataSet" if I try and load it into another DataSet. I can use the .Copy to stop this, but I'm wondering if it's possible to create a DataTable from a DataSet table that has NO reference to the original DataSet?
myDS_Options.ReadXml("options.xml");
myDT_Options = myDS_Options.Tables["Options"].Copy();
myDS_Options.Dispose();
thanks,
Ron

Did you try the Dataset property on the DataTable??
-You just have to change this

Hi,
I am new to .NET, so my apologies if this question is silly. I am wondering, is it possible to send an instance of a class/struct from server to client through remoting, when the class/struct is not defined on the client side?
I need to develop a server that will create user-defined types on the fly using Reflection.Emit, then return instances of these objects to the client. As these types are defined on the fly, there is no way of including the class definitions on the client application.
When I try to do this, I get the error
---
An unhandled exception of type 'System.Runtime.Serialization.SerializationException' occurred in mscorlib.dll
Additional information: Parse Error, no assembly associated with Xml key ...
---
This occurs despite using TypeAttributes.Serializable when creating the type :
TypeBuilder helloWorldClass = module.DefineType("UserType", TypeAttributes.Public | TypeAttributes.Serializable)
|
|
|
|
|
I'm afraid you do need the type definitions on the client side. The standard practice here is to have just the interface definitions on the client side, with the implementation on the server side.

 Hello:
I’m sending a Crystal Reports’s report to Word, but a dialog box is opening where user is asking if wish open/save file.
I’d like avoid this dialog emerges and report be displayed directly in screen as user would press open button.
I’m attaching code I’m using:
string ExportPath = sRuta + "CrystalReport1" + ".doc";
crvReportes.ReportSource = cr;
CrystalDecisions.Shared.DiskFileDestinationOptions DiskOpts = new CrystalDecisions.Shared.DiskFileDestinationOptions();
cr.ExportOptions.ExportDestinationType = CrystalDecisions.Shared.ExportDestinationType.DiskFile;
cr.ExportOptions.ExportFormatType = CrystalDecisions.Shared.ExportFormatType.WordForWindows;
DiskOpts.DiskFileName = ExportPath;
cr.ExportOptions.DestinationOptions = DiskOpts;
cr.Export();
Response.ClearContent();
Response.ClearHeaders();
Response.ContentType = "application/msword";
Response.WriteFile(ExportPath);
Response.Flush();
Response.Close();
System.IO.File.Delete(ExportPath);
Where crvReportes is my CrystalReportViewer y cr is my ReoprtDocument
I’ll thank your help.
A.L.

Why don't you start by stating what it is you're trying to do and in what environment you're using Crystal Reports. From the looks of it, you're trying to mix Crystal Reports from a Windows Forms implementation to ASP.NET, correct? Why is it that you're displaying a report in the first place, especially in ASP.NET? If you're not using ASP.NET, why are you using an HttpResponse (at least it appears that way)?
There is a separate Crystal Reports viewer for ASP.NET that creates files for the web, like HTML for the report and any images that are necessary. You also don't need to display the report just to export it. Just use the ReportDocument.ExportToDisk or ReportDocument.ExportToStream (best for ASP.NET instead of creating temp files on the file system, which requires Write access for the ASP.NET account which leaves your system potentially vulnerable - especially if you write to disk in a directory accessible to web clients).
To open a specific .rpt file, use ReportDocument.Load.
You should consider reading the documentation[^] for using Crystal Reports in Visual Studio .NET for more information and examples. Deploying the CR runtime using the MSMs provided, for example, is a commonly overlooked scenario where users don't include all the necessary MSMs or the registration code you were given when you registered CR for VS.NET. That's also covered in the documentation as well as the class library documentation for CR at http://msdn.microsoft.com/library/en-us/crystlrf/html/crlrfcrystalreportsclasslibrary.asp[^].

Hello:
Surely I need to be more explicit.
I'm using web forms an I’m trying to export a report from a CrystalReportViewer to a location within client machine, I write it therein and then I want display it imto web page, I want avoid dialgog box asking if user want open or save file. I want that it be displayed into a web form without such a dialog, if instead Word document I export it to .pdf format it is displayed directly without such a dialog.
How can I achieve it in Word?
A.L.

You can't. The server does not have direct access to the users' machines. If it did, security would be non-existent. Your code runs on the server. The result of that code is downloaded (pulled) from the server to the client and client-side code runs only on the client. Displaying a report in a web form outputs HTML and once it's downloaded to the client only client-side code can do anything. That's the very nature of HTTP and most other client-server protocols, fortunately.
