Hi,
I have to return corresponding country currency from a function.
I have a disctionary like Dictionary<string,list<string>> that will contain like:
Dictionary<string,list<string>> str = new Dictionary<string,list<string>>();
List<string> currency= GetCurrency();//Will return all currency stored in database.
str.Add("Currency",currency);
Now currency list contains only currency. I would like to add corresponding country also.
I know that I can create datatable,change the dictionary value to DataTable/DataSet type and return..
Datatable is heavy object...So is there any other approach to achieve this?
Many thanks.

Hi,
1.
you should use PRE tags to show code snippets, and HTML-escape all < and > and & signs to make them show properly.
2.
this would be pretty close to what you want:
Dictionary<string,string>currencies=new Dictionary<string,string>();
string country="Belgium";
string currency="Euro";
currencies[country]=currency;
EDIT recased some /EDIT

your really going to post code that mixes case of local variables to help answer a question?

yes it seems I have been on the wrong casing track. All fixed.

I just want to second what Mark Nischalke said in his post.
If you are working on voice recognition, this is hard. If you want to use the built-in libraries (such as those that come with Windows 7) then processing the requests with a general grammer is also hard
By hard I mean its the sort of thing requires a team of researchers. To my knowledge no one has got natural languge processing right yet, even the voice recoginition libraries aren't 100%.

You're talking about a natural speech interface between the user and the computer, like Hal in 2001. You can't afford the hardware, and the software just ain't possible right now. the closest we've come is that Wizard computer that played jeopardy last week, and it was purpose-built to play jeopardy, and do nothing else.

You haven't been listening, now have you...
You just changed the application requirement, the problem is still very much the same.

You'd first need a dictionary of words that get recognized, and no, even the hardcore speech-dictation solutions only recognize the words that it knows.
If it was easy, it would be standard functionality. It's neither.

Don't listen to all the people saying how hard it is, and how you'll never do it.
The iPhone is a good example of this working - it understands a limited range of commands but does make an attempt at recognising names of bands, albums and artists.
e.g. you can say "Play Beatles" - the "Play" is predefined but (one imagines) the "Beatles" is generically algorithmised. (yes, I made up that word)
I think you are right in your idea - here's how I would think about the approach.
Assuming you are looking at a disc. Collect the names of all the top level folders and files, and process the names to sylabalise them (e.g. encode them into a series of syllables) in a similar way to SoundEx.
Then when a command is issued by the user (say, "Open Fred") you first match the command "Open" which is fixed, then compare the sound "Fred" against all of the folders/files previously encoded. And choose the closest match.
Good luck.
And when you have it developed, commercially released, and are rolling in the money, don't forget to come back here and post an "I told you so" message

Could you please explain what this has to do with C#? It looks to me that it would be better in the Web Development forum.

Hi,
I have to display an message to the user when he is uploading a file through File Upload,
In clear, if the file he is uploading is open in his desktop, at that time only i need to display this message like "Close the File Before upload" or etc, if the file he is uploading he is not open in his machine, it has to upload without throwing any message..
The code am used for file uploading is like this...
private void BtnBrowseClick(object sender, RoutedEventArgs e)
{
OpenFileDialog file1 = new OpenFileDialog { Multiselect = false, Filter = "Text File|*.txt" };
if (file1.ShowDialog() == true)
{
new FileInfo(file1.FileName);
using (Stream s = file1.OpenFile())
{
TextReader reader = new StreamReader(s);
reader.ReadToEnd();
txtFileName.Text = file1.FileName;
txtFileName.IsEnabled = false;
}
}
}
So in this code, i have to display an message, in case the file he is uploading is open in his machine, so the file uploading is not possible in that case..
So could u tell me how can i do this...

you first would have to define "open". is it "open" at the functional level (like Notepad or Word is showing the text content), or is it the state the file has from File.Open() to File.Close()?
In the former case, it may or may not be doable. Notepad reads an entire text file and closes it while you can edit it (Proof: open a .txt file and try and delete it while you can edit it in Notepad); Word OTOH keeps the file locked, so you can't delete it while editing.
In the latter case, a File.Delete() would fail. So you could do this:
- make a copy of the file;
- try and delete the original;
- if that succeeds, it was not in use, and you should rename the copy to the original;
- if it fails, the file was not entirely free (either in use, locked, write-protected, ...).
Conclusion: there is no general solution.
Remark: if the upload and the edit could be combined in a single app, then of course that app would know what it is doing, so it could prohibit an upload while editing.

Can't that be done simpler? E.g. with the open method of FileInfo class
fi.Open(FileMode.Open, FileAccess.Read, FileShare.None);
That should cause an exception when the file is in use by Word (of course no chance with Notepad).

No in my Application, i can upload only a file of type *.txt or *.csv,
so could u tell me how can i display a message to the user, when he is uploading a file of (.txt or .csv)type only when that particular file is open in his machine..
As of now in my application, it makes the application crash if that uploading file is open in user machine..
please check my code here..
private void BtnBrowseClick(object sender, RoutedEventArgs e)
{
OpenFileDialog file1 = new OpenFileDialog { Multiselect = false, Filter = "All Supported Files |*.txt;*.csv|Text|*.txt|CSV |*.csv"};
if (file1.ShowDialog() == true)
{
new FileInfo(file1.FileName);
try
{
using (Stream str = file1.OpenFile())
{
TextReader reader = new StreamReader(str);
reader.ReadToEnd();
txtFileName.Text = file1.FileName;
txtFileName.IsEnabled = false;
}
}
catch
{
txtFileName.Text = file1.FileName;
txtFileName.IsEnabled = false;
MessageBox.Show("Please check the file has been Closed before you upload", "LRM..! Manual Feed File Upload");
}
}
}
It is showing warning message if i change the security of that file,but it i think that is not a right way..
So could u tell me the solution, if it needed ignore my code and tell me with a new sample of code..

Hi all, I have an MDI container app with several MDI children forms that can be open at any one time. I had a problem, which I think I've solved fairly elegantly, but which introduced a new problem. Maybe someone here can make suggestions.
The original problem:
Changes on one MDI child form could affect the contents of another MDI child form. So what I did was to have each MDI form implement an interface with a RefreshForm() function. Each MDI child form will the override this function in which the data on the form is repopulated. Whenever a form submits changes to the data source (ie. changes that might affect the contents of any other form, it calls a function which iterates through all the open MDI children forms on the app and calls the RefreshForm() function for each.
The new problem:
The new problem is that, if a user was still busy editing data on Form A, switches to Form B to make changes there without submitting the changes he was busy making to Form A and then submitting the changes he made to Form B, you can already guess what happens. Form A gets repopulated and all unsaved changes are lost. No way around this, at least not that I can think of.
So I was thinking I can override the Deactivate event handler for these forms and warn the user that changes have been made and that these may be lost. I'd like, however, to provide an "OK" and "Cancel" button on the MessageBox, so that the "Cancel" button will take the user right back to the form he was busy editing. But how?
If, in the Deactivate event handler I show a MessageBox and call FormA.Focus() if the user clicks "Cancel", for some reason the newly selected form still has focus as opposed to Form A.
Any advice?

I do believe you are finding out why MDI is not a popular format! I would add an IsEditing flag to the MDI form and refuse to update that form if it is edit mode!
Sooner or later managing all the different states and interactions of a complex MDI app will cause it to crawl up it's own bum and dissapear.
Never underestimate the power of human stupidity

Well said that man. Maintaining an MDI App of any size is excruciating.
|
|
|
|

Thanks, not a bad suggestion. I think I'll do that, and also check whether any of the form's data in the data source has changed and if so, display a big red warning on the form that the data has changed and this form cannot be saved anymore - or something like that.
I'm surprised to hear you saying that MDI is not a popular format. What would be a popular format then for something like say a CRM applications? Say for instance, you're looking at the details of a customer and then, without having to close that customer and later opening it again, you want to see a list of orders that customer has placed. And then, without having to close that list of orders and later opening it again, you want to see the shipping details for a particular order.
MDI just seemed to me like the perfect format for this kind of application (and of course it brings with it all sorts of extra challenges). But I'd be interested to know what a more appropriate format would be.
