download crystal reports 2005 merge modules

Crystal Reports uses merge modules to verify the correct crystal report components and assemblies are installed with your deployment project.

A merge module is a set of components that are merged with a Windows installer for applications that need them. The components may include a .dll file, resources, registry entries, setup logic, and related files. With all related components stored in a single container, the installer eliminates version conflicts and other common installation problems.

Read Pdf file using c#

So you’ll have to download the PDFBox package. In this package you’ll find a bin directory. To read your PDF file, you’ll need the following files:

* IKVM.GNU.Classpath.dll
* PDFBox-0.7.3.dll
* FontBox-0.1.0-dev.dll
* IKVM.Runtime.dll

PDF Box Package is free distribution tool







You’ll have to add a reference to the first two in your project. You’ll also have to copy the last two on your project’s bin directory.


The program will look something like this (if you’re working with a Console application):



using System;
using org.pdfbox.pdmodel;
using org.pdfbox.util;
namespace PDFReader

{
class Program
{
static void Main(string[] args)
{
PDDocument doc = PDDocument.load("lopreacamasa.pdf");

PDFTextStripper pdfStripper = new PDFTextStripper();

Console.Write(pdfStripper.getText(doc));
}

}

}

Bind countries from CultureInfo class in C#

Some people have asked me how BlogEngine.NET displays a dropdown list of countries when no source XML file is present. The simple answer is that you don’t need any external list to bind to from C#, you can instead use the CultureInfo class.

Consider that you have the following dropdown list declared in an ASP.NET page:



Then from code-behind, call this method which binds the countries alphabetically to the dropdown:

public void BindCountries()
{
System.Collections.Specialized.StringDictionary dic = new System.Collections.Specialized.StringDictionary();
System.Collections.Generic.List col = new System.Collections.Generic.List();

foreach (CultureInfo ci in CultureInfo.GetCultures(CultureTypes.AllCultures & ~CultureTypes.NeutralCultures))
{
RegionInfo ri = new RegionInfo(ci.LCID);
if (!dic.ContainsKey(ri.EnglishName))
dic.Add(ri.EnglishName, ri.TwoLetterISORegionName.ToLowerInvariant());

if (!col.Contains(ri.EnglishName))
col.Add(ri.EnglishName);
}

col.Sort();

ddlCountry.Items.Add(new ListItem("[Not specified]", ""));
foreach (string key in col)
{
ddlCountry.Items.Add(new ListItem(key, dic[key]));
}

if (ddlCountry.SelectedIndex == 0 && Request.UserLanguages != null && Request.UserLanguages[0].Length == 5)
{
ddlCountry.SelectedValue = Request.UserLanguages[0].Substring(3);
}
}

The method first adds all the countries from the CultureInfo class to a dictionary and then sorts it alphabetically. Last, it tries to retrieve the country of the browser so it can auto-select the visitors country. There might be a prettier way to sort a dictionary, but this one works.

Why use interface ?

The following 2 examples will give bit more insight into use of interfaces. The first example explains how interface can be ploymorphically used. The second one explains how it can be used for multiple-implementation. Both the examples combined also describe a ISP or Interface Segrigation Principle.

Example 1: [Polymorphism] Suppose you have an application that writes data into different devices say HDD, FDD and CDW, in a buffered mode. Any number and any media may be used. It should also be possible plug-in/out any device any time. Each device has its own implementations. How do you ensure that this can be done without knowing the specific implementation of the device?

Solution: Lat them all implement an interface that defines common operations. The application can use the interface to make polymorphic calls.

public interface IMedia
{
void FlushData();
void OpenMedia();
void WriteData(Stream dataStream);
}

public class CDW : IMedia { ... }
public class HDD : IMedia { ... }
public class FDD : IMedia { ... }

public class DataApplication
{
CDW _cdw = new CDW(...);
HDD _hdd = new HDD(...);
FDD _fdd = new FDD(...);

IMedia _mediaDevices[] = new IMedia[] ({_cdw, _hdd, _fdd });

private void SomeDataWriteTask()
{
_cdw.WriteData(someDataStream);
_hdd.WriteData(someDataStream);
_fdd.WriteData(someDataStream);
}

private void Close()
{
foreach(IMedia mediaItem in _mediaDevices)
{
// Ploymorphic call to flush the buffered
// data into correct implementations.
mediaItem.Flush();
}
}
}

Example 2: [Multiple Implementation] Continuing the above example now suppose you have another diagnosis application that needs to check few common performance factors of these devices. The dignostic application need not know the details of these implementations. However the DataApplication (application above) should not have any knowledge of these tasks. How to do this?

Solution: Let each media implement an interface that the diagnostic application can use to operate upon. So the modified design looks like:

public interface IMedia
{
void FlushData();
void OpenMedia();
void WriteData(Stream dataStream);
}

public interface IMediaMonitor
{
long GetSeekSpeed();
long GetSizeInBytes();
void MoveToOffset(long offsetPosition);
}

public class CDW : IMedia, IMediaMonitor { ... }
public class HDD : IMedia, IMediaMonitor { ... }
public class FDD : IMedia, IMediaMonitor { ... }

public class DiagnosisApplication
{
private void DoHealthCheck(IMediaMonitor someMedia)
{
IMediaMonitor mediaDevice = someMedia;

long l1 = mediaDevice.GetSeekSpeed();
long l2 = mediaDevice.GetSizeInBytes();
mediaDevice.MoveToOffset(0);
}
}
