Alternating output of two dictionaries

12-Sep-09 5:34

As far as libraries go Google for c# pdf libraries and take your pick. There are lots of established ones like PDFSharp, ITextSharp etc. but that search listed several that I have no experience of.

Images of a PDF page? Same thing applies, Google for c# image of pdf page, and it's "eany meany miney mo". The first on the list I got was Generate Thumbnail Images from PDF Documents[^], which although it is VB and gives thumbnails, should suggest a few things. If you don't like that one, pick another, there are loads of hits after all. Smile | :)

I have two dictionaries that I output to two separate DataGridViews. I need to be able to alternate the output of the two dictionaries to one DataGridView. Any help would be appreciated.

Then just do so by writing some code.

The two dictionaries better have the same number of entries, otherwise you'd have to come up with a more precise specification.

BTW: Right now I can't imagine an application domain where your requirement makes sense.

I am differencing two files. Each file's specs are put into a dictionary and then output the two files into two separate DataGridViews. Then differences are colored. I am required to show these in a single DataGridView where one line of the gridview is outputted from one dictionary and then the other dictionary is outputted as they alternate. The dictionaries can have different amout of entries as one file may have more or less records than the other.

File Permission

I was just trying to give file premission to my dummy files but encountered a problem. I found out that only the last applied permission is imposed on the file while rest are overriden or not applied.

using System;
using System.IO;
public class RegistryEditor
{
    public static void Main()
    {
        try
        {
            FileInfo f = new FileInfo(@"C:\Test.txt");
            f.Attributes = FileAttributes.System;
            FileInfo f1 = new FileInfo(@"C:\Test.txt");
            f1.Attributes = FileAttributes.ReadOnly;
            FileInfo f2 = new FileInfo(@"C:\Test.txt");
            f2.Attributes = FileAttributes.Hidden;
            FileInfo i = new FileInfo(@"C:\Test1.txt");
            i.Attributes = FileAttributes.System;
            i.Attributes = FileAttributes.Hidden;
            i.Attributes = FileAttributes.ReadOnly;
        }
        catch (Exception ex)
        {
            Console.Write(ex.ToString());
        }
    }
}

Hi,

int i;
i=1;
i=2;
i=4;

Now what is the final value of i? Is it 7? Why would it be any different with file attributes?

File attributes are flags, i.e. they have a binary pattern with one bit set, all others cleared. So you can OR them together (with the '|' operator) to get combinations of them.

Assume it works: the attributes for the file are now "System"

Had you considered?

FileInfo f1 = new FileInfo(@"C:\Test.txt");
f1.Attributes += FileAttributes.ReadOnly;

What are the attributes now?

I told you, you would kick yourself!

Except that if it already was ReadOnly, it will be Hidden and not ReadOnly anymore. (ReadOnly = 1, Hidden = 2)

OriginalGriff,
Yes, i had considered

FileInfo i = new FileInfo(@"C:\Test.txt");<br />
i.Attributes += FileAttributes.ReadOnly;<br />

But this gives an error Operator ' += ' cannot be applied to operands of type 'System.IO.FileAttributes' and 'System.IO.FileAttributes'.
Luc Pattyn,
ThankYou. Your suggestion worked.

I am trying a program to add keys, however i am getting an exception saying
System.UnauthorizedAccessException : Cannot write to registry key
You can consider me beginner in registry editing issue.

using System;
using System.Security.Permissions ;
using Microsoft.Win32;

public class RegistryEditor

    {
        try
        {

            RegistryKey hkSoftware = hkcu.OpenSubKey("Software");
            RegistryKey hkMicrosoft = hkSoftware.OpenSubKey("Microsoft");
            RegistryKey hkIshaan = hkSoftware.CreateSubKey("Test1");
            hkIshaan.SetValue("Name", "Ishaan");

Re: Registry Editing

Henry Minute12-Sep-09 3:28

Two things:

1) You can concatenate your two OpenSubKey calls:

RegistryKey hkMicrosoft = hkcu.OpenSubKey(@"Software\Microsoft");

2) The OpenSubkey has 4 overloads. If you look it up on MSDN the last one allows you to specify the RegistryKeyPermissionCheck (what you can do with subkeys), and RegistryRights (read only, read/write TakeOwnership etc.).

I am still on XP, so I don't know how this applies under Vista and Weven, which I know are a bit more picky about these sorts of things.

Hope that this is of some help! Smile | :)
