How to insert an unicode (e.g letter "A" with circumflex) into wordpad(at current cursor position)
from c# program?
|
|

|

Just give you an idea. Why don't you make a format file. Then call this file into to your C# code.
Format File example:
1 SQLNCHAR 0 6 "\0" 2 MANDT ""
2 SQLNCHAR 0 20 "\0" 3 LIFNR ""
.

Hi All,
I have a custom generic list defined with:
namespace DataLayer
{
public class ExportFile
{
private string _path;
private string _fileName;
public string Path
{
get { return _path; }
set { _path = value; }
}
public string FileName
{
get { return _fileName; }
set { _fileName = value; }
}
public ExportFile(string _path, string _fileName)
{
Path = _path;
FileName = _fileName;
}
}
}
Being populated like:
void xamDataBaseView_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
DataRecord dr = xamDataBaseView.ActiveRecord as DataRecord;
if (dr != null)
{
DataRowView drv = dr.DataItem as DataRowView;
string _path = drv.Row.ItemArray[4].ToString();
string _name = drv.Row.ItemArray[1].ToString();
exportlist.Add(new ExportFile(_path, _name));
listboxExport.Items.Refresh();
}
}
But in the listbox on the UI the contents is shown as:
DataLayer.ExportFile
I'm not entirely sure what I'm doing wrong here. Why is it showing the Type and not the data in the exportlist ...
Cheers,
Jammer

You need to override the ToString() and format the values to be displayed in the ToString(), if it is a ListBox type of control.

Hi Guy
when bind generic object to gui , u must get object from ur class, then assign listbox.items.add()
And what is this "exportlist" ? i'm assuming this is listbox,
then ur code must be '
exportlist.items.add(new object('' ,''))
thnaks

Thats not even valid code, there is no constructor of Object which takes 2 char vales.

Hey
i wrote a sample code regards his object.
thanks.

The answer is pretty simple, you should have to set the DisplayMember and ValueMember of the ListBox to the names of the properties on your ExportFile which you want to use for display and value.
In your case you might want FileName for the DisplayMember and the ValueMember - but you're free to use any properties of the object being put into the List.

Fantastic that is exactly what the doctor ordered.

Hey
There many way write log file.
So You must decide what i want to include within log file, then select a way.and write log file.
1.must use simple object
2.u must close file or stream immediately when u written
3.don't put garbage within log file
4.use the simple phrases.
that's all.

I'm hoping there's a more streamlined approach to this. In a form, I have 7 textboxes and a button. When the button is clicked, each textbox needs to be looked at to ensure it contains something. If the textbox is blank, I have a label on the forum to alert the user of such. Then I direct focus to the blank textbox. So far I've been doing it like this:
if (txt1.text == "")<br />
{<br />
ErrorLabel.text = "Enter something in txt1";<br />
txt1.focus();<br />
}<br />
else if (txt2.text == "")<br />
{<br />
ErrorLabel.text = "Enter something in txt2";<br />
txt2.focus();<br />
}<br />
else if (txt3.text == "")<br />
{<br />
ErrorLabel.text = "Enter something in txt3";<br />
txt3.focus();<br />
}<br />
else if (... and so on, and so on for all 7 textboxes)
Is there a way to do it with less code?

Realistically you should create a class that implements the data that you want, and then put a binding against the textbox. With a bit of the magic listed here[^] you can save yourself a lot of work keeping validation and items in sync.

That's a great article. Do you know any similar approach available for web application ?
|
|
|
|
|
You could adapt it using techniques described in this[^] article.
|
|
|
|
|
if you don't want to go with databinding which is a good option, you can combine all the if statements:
if(txt1.Text=="" OR txt2.text=="" OR txt3.text="" OR ...)
{
ErrorLabel.text="All fields must be entered to continue";
}
Their still may be better options though.

Why dont you just use required field validators?
|
|
|
|
|
*Clicks the Back Button2*
"Please fill in all the fields to continue" >
The reason I've stopped using RequiredFieldValidators....
|
|
|
|

How about this:
<br />
<br />
foreach (var tb in new TextBox[] { txt1, txt2, txt3, txt4, txt5, txt6, txt7 }) {<br />
if (tb.Text == "") {<br />
ErrorLabel.text = string.format("Enter something in {0}", tb.Name);<br />
tb.Focus();<br />
break;<br />
}<br />
}<br />
<br />
It aint pretty, and I'd prefer data binding, but it'd work?
|
|
|
|
|
If you set required field validators when tabbing to each textbox it instantly does validation i dont see the issue perhaps ive misinterperted your query

That's what I would do too... so it must be wrong somehow. 
|
|
|
|
|
I'll give this a shot .. looks interesting
I'd do databinding, but not sure how. I'm still new at this. If I created the DB within Visual Studio I'd be able to do it, but it's created at runtime (SQL CE)
EDIT: I just tried it, and it worked great. Thanks!!!

Or set the Button's Enabled property
btn.Enabled = ( txt1.Text.Length > 0 ) && ... ;
