why are you making everything much more complex than necessary?
dictionaries (SortedList is a dictionary) require keys to be unique, which does not match your application; so forget about dictionaries as your primary storage.
you can keep a list of strings (any strings including duplicates) in a List<string> which you can simply sort by calling myList.Sort()
you can also define your own little class "MyType" (holding name, age, address, vehicleColor, whatever) and collect those in a List<MyType>
Strings get sorted alphabetically by default; your own objects don't have a default sort order. If you need a (special) sort order (i.e. non-alphabetic for strings) you can easily do that with an object that implements IComparable; I wrote a little article[^] that explains it all.
FWIW: I strongly recommend you buy and study a book on C# to increase your basic knowledge of the language and the .NET framework. Here[^] is why.

My answer to that is because the program that i'm creating is for the subject that i have about data structures. I can't use Array.Sort() etc because the solution that we presented is to use radix sort(which i didn't continue because I can't resolve the error i always get). We have a different subject for the fundamentals and other things about C#.
But I'll take your advice. I already visited the links that you posted and read it especially about learning a new language. I already have a book, the title: C# Programming: From Program Analysis to Program Design by Barbara Doyle. But probably I'll do what you said there so I can have more knowledge about the language.

OK
Now SortedList is not dealing with duplicate keys and not doing Radix Sort, so it is a bad choice.
What you need is create your own collection class, probably inheriting from List<string> or List<MyType>, start by using its normal Sort method, later on override the Sort method with your own (for which I already gave the basic principles in another thread).

Hi,
I have a Form called from another Form. I've put events in both forms. The called forms mouse events aren't being triggered. The OnClosing event is triggered. Any and all help appreciated!

Too much code!!
So badly formatted that it is impossible to read.
Cut it down to ESSENTIAL code only and enclose it in <pre></pre> tags to preserve code colouring and formatting.
Somebody might then be able to help you.

Hi,
Im making an c# asp.net application. I would like to open an bin file and read the character by character. the intention is to get the most attentive characters.
Like if the content is çüëýýýëþõõ , the result must be ý. Because there are 3 characters like it.
Here are 2 pictures to see the content of the bin file:
Hex editor
Notepad
Is it possible with StreamReader ?
|
|
|
|
|
Yeah use StreamReader.BaseStream.ReadByte() that will give you a byte which you can convert to a char or hex value or int or whatever you want
Life goes very fast. Tomorrow, today is already yesterday.
|
|
|
|
|
NO
if you want to treat the file content as binary data, then you should not use anything related to characters, strings or StreamReaders, so File.OpenText() is of limits, use File.OpenRead() instead; that returns a FileStream which has Read and ReadByte methods.
Your Notepad link clearly proves the data isn't text I would say.
BTW: your question is not related to hex at all, the data is non-textual or binary, which you could show in hex format (as the left half of your hex editor does) but that is just a way of looking at it, it is not what is in there.

Good day!
I am finally rewriting an 10 year old device-communication application in .Net. The original program uses a series of VB6 DLL's (also developed by me) to connect with all the different devices.
There are about 20 or so DLL's most of them rather unique and it would be an extremely cumbersome task to re-write all of them in .Net.
I want to create an Interface and make the DLL's conform to that.
When I try adding my DLL's in .Net it wants assembly data, which I don't have.
What is the easiest way of exposing a such a DLL's methods?
And how would I go about using an Interface to define the classes from the DLL's? (I will modify the DLL's to expose the correct methods).

You must have missed the part where I said LATEBINDING.
But thanks anyway.
|
|
|
|

If you want to perform late binding, you need to follow the following steps. You need to use Type.GetTypeFromProgID to retrieve the type from program ID that you want to work with, e.g. Word.Application. Create the object using Activator.CreateInstance and then use calls like InvokeMember to invoke methods in the DLL.

Hi Pete
My apologies for only replying now.
I think my problem is that there exists no such Program ID on the system, according to what I've read in Microsoft's documentation, there is a registry entry for every valid program ID. My application however, retrieves the DLL file from a DB (in a BLOB field), saves it on the HDD and then attempts to work with it.
That last bit is where I'm stuck. Do I need to register the DLL with the system in order for it to be a valid ProgramID? And furthermore, I see that the programID always conforms to {Application}.{Class} or so it seems, I'm not even sure what my DLL's programID will be even if I do manage to use it in this manner.
I'd appreciate any help you may be able to provide.
Kind Regards!

Hi experts,
I am looking for code to generate thumbnail for the first page of Microsoft Office document (such as word,excel) and PDF. I found sth like this in MSDN and tried it, however, what is the missing reference for "Doc" as in the first line. What reference should I use for the "Doc"?
InlineShapes shapes = Doc.InlineShapes;
int i = 0;
foreach (InlineShape shape in shapes)
{
if (shape.Type == WdInlineShapeType.wdInlineShapePicture)
{
shape.Select();
shape.Application.Selection.CopyAsPicture();
IDataObject data = Clipboard.GetDataObject();
if (data.GetDataPresent(DataFormats.Bitmap))
{
Image image = (Image)data.GetData(DataFormats.Bitmap, true);
image.Save("c:\\111.bmp"), System.Drawing.Imaging.ImageFormat.Bmp);
}
}
}
Could anybody kindly help me with this? Will this code do the job or you guys have better solutions? Thank you very much.
Chris

You would be far better served by buying a book or two.
The information you have asked for is far too complex and long to be covered in a forum such as this.

Hi all. I want to get the columns in a DataGrid as an Array and i am trying such a piece of code:
foreach (DataGridViewColumn column in dataGridAppointments.Columns)
{
...
}
Where dataGridAppointments is a DataGrid control. I keep on getting the error message:
'System.Windows.Forms.DataGrid' does not contain a definition for 'Columns'.
How can i manage to loop through the collection of columns.

dataGridAppointments is not a DataGridView.
