The problem that I want to print in the same page ,that contains informations printed with e.Graphics.DrawString () I want to print command PCL but the problem is that I have in the result 2 pages.

- the first one contains informations printed with e.Graphics.DrawString ().
- The second contains informations of PCL command

The problem that I want in the result 1 page that contains both information.

I send To you a part of my code:

code use e.Graphics.DrawString ():

PrintDocument Page = new PrintDocument(); Page.PrintPage += new PrintPageEventHandler(cardDocument_Page); Page.Print();

Code of cardDocument_Page(....):

e.Graphics.DrawString("String1", cardFont, Brushes.Black, 400, 300);
e.Graphics.DrawString("String2", cardFont, Brushes.Black, 500, 300);

Code that send commande directely to the printer:

DOCINFO di = new DOCINFO();
int pcWritten = 0;  
PrintDirect.OpenPrinter("\\\\10.1.0.40\\HPLaserJ", ref lhPrinter, 0);
PrintDirect.StartDocPrinter(lhPrinter, 1, ref di);
PrintDirect.StartPagePrinter(lhPrinter);  

string st1;
st1 = "\x1b**1M\x1b(14Y\x1b(s0p8.00h12.0v0s0b105T" + Strin+ "\x1b**0M";

 PrintDirect.WritePrinter(lhPrinter, st1, st1.Length, ref pcWritten);  
PrintDirect.EndPagePrinter(lhPrinter);
PrintDirect.EndDocPrinter(lhPrinter);
PrintDirect.ClosePrinter(lhPrinter);

classes used by  PrintDirect:
public class PrintDirect { [DllImport("winspool.drv", CharSet = CharSet.Unicode, ExactSpelling = false, CallingConvention = CallingConvention.StdCall)]
public static extern long OpenPrinter(string pPrinterName, ref IntPtr phPrinter, int pDefault);

I'm trying to save a unicode utf8 string --> "سلام" in a feature of a featureclass, but it is saved like "????".as ArcMap support different encodin and also Farsi that I'm working with, It should be possible through my program.but I didn't find any way yet.anybody knows about this?

<br />
                        <br />
                        feature = fc.CreateFeature();<br />
                        feature.Shape = point;<br />
                        feature.set_Value(feature.Fields.FindField("Name"), o.Name);<br />
                        feature.Store();<br />

fc is an IFeatureClass, feature is an IFeature and o.Name is a unicode.utf8 string.in watch window:
feature.get_value(feature.Fields.FindField("Name"))--> is OK
but
fc.GetFeature(1).Get_Value(feature.Fields.FindField("Name")) --> is "????"

and this is what is saved. What should I do? Cry | :((

If you're sure that your data is intact when sent to the component (easily checked with some breakpoints) then you should ask in their forums[^].

Hi,
I have to develop UI in windows mobile in which the icons come one by one in a line by using left/right key (AS developed in iphone). The selected icon gets focus and enlarged, others are going in background of screen.
How to develop ?

object instance shared across entire application

jackgeek18-Jun-09 3:54

I am writing a Windows.Forms application and I have a some objects that I want to be Global. Example of these objects are an object for maintaining a collection of remote resources, and a "Task list" type object that shows all running tasks. There is only ever 1 instance of these objects, they are created when the application starts and are destroyed when the application ends.

I use these objects throughout my application and inorder to do so I have to pass an "Environment" object to each form, this Environment object serves as a pointer to the global objects.

This seems very kludgy, is there a way that you can have global objects shared across the application without having to pass them to each form/thread you create?

Thanks in advance!

If I understand correctly, you need a object TaskList across the application. Assuming it has a set of properties, you can have a public static class TaskList, with all the properties needed, which will be available across the application.

If it is just a list of tasks and there are some more things of this sort, have all these as properties in a common static class and expose them as properties of type List.

Since the class would be public, you can access it anywhere in the application.

The public static class contains the global object instance (or is the global object if you prefer).

public static class GlobalObjects
   {
   public static List<Task> taskList = new List<Task>();
   }

...

   GlobalOjects.taskList.Add(task);
...

The thing you're looking for is called a singleton - something there's only ever one of and in general can be got from anywhere.

Hi, I am using EF and want to use its generated objects to be returned to the web service (By serializing it). The problem is All generated classes are inherited from EntityObject (member of System.Data) and I don't want its member to be included in the wsdl.

Please help me if anyone know the solution. Thanks in advance.

Create DLL out of a C# Project

18-Jun-09 1:39

Hi,

I have a windows application, reporting-tool, wich alows a user to create a XML that later can be generated to a Excel-File.
I am now developing a new function. The user should have the possibility to create a DLL consisting model/generator and also the created XML. By now I have splited the application into two projects:
1. The main windows application with all the forms etc.
2. The model of the excel-report and the classes which generate the report.

Now how can I create the DLL and embed the XML, and all that should be implemented in the windows application project

Thanks in advance

You create an assembly by using a compiler, but I'm at a loss to understand why you are having users create them. How would the be used?

Create an assembly by using a compiler? Could you be a bit more specific D'Oh! | :doh:

It's a windowsapplication that uses COM-Interop to create a excelfile. The XML file has stored the definition for the report, like position of the cell, cell-content, cell-format etc.
Generation the excelreport works fine. But the next step is to create that DLL.
When the user has created that DLL he can upload it to a ASP.Net application which handels that DLL and provides the report as a download.
It has to be a DLL consisting the C#Project(model/generator) and the XML Definiton-File. Unsure | :~

Woah! You are allowing users to upload DLL files to a web server?! Are you nuts! Can you not see what a massive gaping security hole you are punching in the Web server? It would be like a bank saying that they want to make it easier for their customers to access their money, so here's a stick of dynamite to use if you ever need to access the vault out of hours.

My primary concern was to ensure that you understood, in the quickest way possible, the severity of risk in your actions.

It is your problem. You already have an idea of how it will be used. You now have an idea that it is an extremely risky solution to the problem.

How to save a webpage using ExecWB() in c#

when IE is opened, internally I have to save the page on some specified path( as C:\abc.html)
this is code trying
object pvaIn = new object();
object pvaOut = new object();
pvaIn = webBrowser.Document;

pvaOut = @"C:\abc.html";
webBrowser.ExecWB(OLECMDID.OLECMDID_SAVE, OLECMDEXECOPT.OLECMDEXECOPT_DODEFAULT, ref pvaIn, ref pvaOut);

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
