Hello All,
I am trying to do this:
using System.Web.Mail;
and Visual Studio tells me that:
The type or namespace name 'Mail' does not exist in the class or namespace 'System.Web' (are you missing an assembly reference?)
What am I missing here?
Thanks!
Ed

Hi,
You have to add a reference to System.Web.dll before you can access the namespace.

Under your references in your solutions explorer (right click) add a new reference to System.Web
That will help!

Helo 
I know that I have done this before, controling how the output-xml is formated.
The default i:
<NewDataSet>
<table>
<col1>val</col1>
<col2>val</col2>
</table>
<table>
<col1>val</col1>
<col2>val</col2>
</table>
<NewDataSet>
But I want it to be:
<NewDataSet>
<table col1="val" col2="val">
<table col1="val" col2="val">
</NewDataSet>
What is the property to set ????

Do you have a schema? You need one to achieve this.
In VS, open the <yourschema>.xsd file,and click on DataSet tab at the bottom. You will see a table named table (as your example) and the columns with their types. You will see in the first column an E, change it to an A and there you go.
If you don't have a schema, simply build by hand a XML file that will look like what you want. Open it with VS and choose, from the XML menu, Create Schema.
In your program, before loading the DataSet with data from an XML file, or before saving to an XML file, use one of the myDataSet.ReadXmlSchema methods. When reading, always use the XmlReadMode.Auto and maybe set the myDataSet.EnforceConstraints property to true to detect any schema errors.
Have fun!

You can set the ColumnMapping property on each column to MappingType.Attribute.

:-DGreat!
That was the best and eazyest solution.
To solve it with XMLSchema created alot of overhead and
puluted the xml with alot of xmlns-information...

Hi,
I have two lists (A and B).I want to add some items from A to B and remove the items from A. I've used two ListBoxes for this situation.
I want to display Name of items and for adding and removing I have to know ID of each item. So I use ListBox.DataSource to fill items. First I define a class:
<br />
public class USState<br />
{<br />
private string myShortName ;<br />
private string myLongName ;<br />
<br />
public USState(string strLongName, string strShortName)<br />
{<br />
<br />
this.myShortName = strShortName;<br />
this.myLongName = strLongName;<br />
}<br />
<br />
public string ShortName<br />
{<br />
get<br />
{<br />
return myShortName;<br />
}<br />
}<br />
<br />
public string LongName<br />
{<br />
<br />
get<br />
{<br />
return myLongName ;<br />
}<br />
}<br />
<br />
public override string ToString()<br />
{<br />
return this.ShortName + " - " + this.LongName;<br />
}<br />
}<br />
Then for filling list items :
<br />
ArrayList USStatesA = new ArrayList() ;<br />
ArrayList USStatesB = new ArrayList() ;<br />
USStatesA.Add(new USState("Alabama", "AL"));<br />
USStatesA.Add(new USState("Washington", "WA")) ; <br />
USStatesA.Add(new USState("West Virginia", "WV"));<br />
USStatesA.Add(new USState("Wisconsin", "WI")) ;<br />
USStatesB.Add(new USState("Wyoming", "WY"));<br />
<br />
ListBoxA.DisplayMember = "LongName" ;<br />
ListBoxA.ValueMember = "ShortName" ;<br />
ListBoxA.DataSource = USStatesA ;<br />
<br />
ListBoxB.DisplayMember = "LongName" ;<br />
ListBoxB.ValueMember = "ShortName" ;<br />
ListBoxB.DataSource = USStatesB ;<br />
Everything is OK by above codes. But the problem is: When I Remove an object from ListBoxA and then Add it to ListBoxB; no changes will be appear in ListBoxA.Items or ListBoxB.Items .
How can I update ListBox Items same as its DataSource updated?
regards,
Mehdi

One method that will work is to invoke the Refresh method of the Currencymanager objects involved, e.g. after you've moved an object from one ArrayList to the other:
CurrencyManager cm = BindingContext[USStatesA] as CurrencyManager;<br />
if (cm != null) cm.Refresh();<br />
cm = BindingContext[USStatesB] as CurrencyManager;<br />
if (cm != null) cm.Refresh();
A nicer method might be to wrap the ArrayLists (or derive from them) in an object of your own which implements the IBindingList interface. This allows an event to be raised when the list is changed, and I assume that the CurrencyManager traps this event and automatically updates the bound controls (but this is based only on my understanding of the documentation - I haven't tried it  ).

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();

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[^]

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

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.

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").

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?
