GetLocaleInfo for .NET? - C# Discussion Boards

Thanks Chris.
I think I didn't write the problem clearly. I tell you it again.

I write below method to remove an item from ListBoxA and add it to ListBoxB:

<br />
void TransferItem()<br />
{<br />
	object SelectedObject = ListBoxA.SelectedItem;<br />
	((ArrayList)ListBoxA.DataSource).Remove(SelectedObject);<br />
	((ArrayList)ListBoxB.DataSource).Add(SelectedObject);<br />
}<br />

By this method the DataSource of ListBoxA and ListBoxB has been changed, but no changes will be appear in ListBoxA.Items and ListBoxB.Items .
I couldn't change the Items directly because of using DataSource for ListBoxes.
Can you help me please.

Mehdi,

If you add the code I gave, or the following modified version of it, at the end of the TransferItem method in your previous posting it should work:

CurrencyManager cm = BindingContext[ListBoxA.DataSource] as CurrencyManager;<br />
if (cm != null) cm.Refresh();<br />
cm = BindingContext[ListBoxB.DataSource] as CurrencyManager;<br />
if (cm != null) cm.Refresh();

Adding a progressbar to a statusbar

Hi there,

Is it possible to add a ProgressBar control to a status bar or do you simply have to make the status bar panel owner drawn?

Thanks in advance

Hi, I may be mistaken but I think that you cannot place controls into a StatusBar control in the designer. However, you can add any number of Controls to the StatusBar programatically through it's Controls property.

Hope this helps

Hey don't worry, I can handle it. I took something. I can see things no one else can see. Why are you dressed like that?

Thanks Chris! I'll give it a try.

// Edit

Gave it a try. It works...the problem is that is always inserts the progressbar as the very first item on the statusbar. I tried using the SetChildIndex method of the Controls collection but it had no effect. Any ideas?

Try writing a StatusBarPanel derived class as described in http://www.dotnet247.com/247reference/msgs/20/102483.aspx[^]

GetLocaleInfo for .NET?

What's the equivalent of the Win32 API GetLocaleInfo for .NET?

Thanks,

I think the CultureInfo class (from System.Globalization) might be what you're looking for.

Yes, thanks, that's the one.

Do you know if there's a mapping of Win32 APIs to their equivalent namespace.class.methods in .NET. Something like that would help a lot of people like me who are porting apps from Win32/MFC to .NET.

For example, I just ran into another one. What's the equivalent for VK_DELETE? Well, I had to search for a few minutes before I discovered the System.Forms.Keys enumeration.

Thanks again,
Alvaro

I need to determine the amount of records in a database table without looping through the tables records one by one, that seem to be very slow over a 33kbps connections if you got 20,000 records???

In order to find out the number of records in a database table "table", use the SQL Command:

Select count(*) from table

In general, try to get familiar with SQL and what it can do for you. It can do a LOT more than procedural code.

J# Not C#

I thought you guys might be able to help.

I am still undecided about J#. Can anyone explain why the code snippet below would work in J++ but not in J#. The code compiles okay but it cant find the text file to read from. Instad, the exception I catch is J# filenotfoundexception. The text file is in the right directory. Anyways, appreciate any help.

public static String[] getIndonesianwordList(String file){
String IndonesianwordList[] = new String[9];
try{
BufferedReader in = new BufferedReader(new FileReader(file));
String s;
int i = 0;
while((s=in.readLine())!=null){
StringTokenizer tok = new StringTokenizer(
s,DELIMITERS);

while(tok.hasMoreTokens()) {
String nextWord = tok.nextToken();
System.out.println(nextWord);
IndonesianwordList[i] = nextWord;//wordList.add(nextWord);
i++;
}

}
}
catch(IOException e){
System.out.println(e);
System.out.println("error loading array");
}
return IndonesianwordList;
}

Just a guess, but maybe J# requires a fully qualified path name for FileReader (e.g., "C:\temp\foo.txt" rather than "foo.txt").

Mirroring Explorer Functionality

I am creating a small application that will goto a specific directory, display its contents, etc - basically the window where the dir contents is displayed should have the same functionality as a normal explorer window :

i.e.
Drag/Drop
Listing/Sorting functions
Double Click to open

I assumed that this would be fairly simple, but after some surfing around it seems that is not the case at all.

Does anybody have any experience of this?

Well after a few hours of looking around I have come up with a grand total of nothing.

So I have started to write my own, so far so good, but I have encountered a stumbling block - I cant find any code to open a file given its path.

For example, I am trying to open the following file :

C:\skunkworks\directoryviewer\test.txt

Does anybody have any info on achieving this?

I have been looking through this article :

http://www.codeproject.com/csharp/csdoesshell2.asp[^]

But it all seems to much to simply open a file in whatever the associated application.

I have found a solution to the file opening problem I mentioned above, just incase somebody is searching these forums for a similar answer this is the code I used :

<br />
FileInfo launchfi = new FileInfo(strDocumentPath);<br />
Process proDocument = new Process();<br />
proDocument.StartInfo.FileName = launchfi.FullName;<br />
proDocument.StartInfo.WorkingDirectory = launchfi.Directory.FullName;<br />
proDocument.StartInfo.UseShellExecute = true;<br />
try<br />
{<br />
	proDocument.Start();<br />
}<br />
catch<br />
{<br />
	MessageBox.Show("Unable to open selected document. If this problem persists please contact your Administrator.", "Document Open Error", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);<br />
}

.NET & Visual Studio 6.0

Hi there
Basically whats the avantage of .NET over Visual studio 6.0.Many Ppl say that Common language Specification is the Advantage.
Do they mean that a code writtern in VB .NET can be used in C#?
If so we can very well write a dll in VB, that can be used in VC++.

Plz make me clear on this stuff .
Thanks in adv.

the difference is mainly
1) common class library across languages.
2) class/object reuse across languages.

you can't do this is vb/vc++ - you can provide a dll interface, but thats at a function level, not an object level.

of course you can get the same results with vb/vc++ and some clever programming, but the whole point is the M$ have done it for you.

its all about productivity.
