Hi
Yeah, It was more how to get a Class to show a child form in a Mdi Form
<br />
{<br />
if (frmClientInfo.Visible)<br />
{<br />
frmClientInfo.Focus();<br />
}<br />
else<br />
{<br />
frmClientInfo.MdiParent = frmMain;<br />
frmClientInfo.Show();<br />
}<br />
}<br />
} <br />
}
That didn't work

frmClientInfo.MdiParent = frmMain;<br />

Hi all,
Any idea about how could I return an array from the JavaScript code of a WebBrowser control? In another words: returning an array from a call of Document.InvokeScript.
Thank you.
Bogdan.

|
|
|
Use JavaScript's return statement.
|
|
|
|
|
 Well, it seems that it didn't cross my mind...
Anyway, assuming that I do that, how should I interpret the answer on the .NET side? Chances are to get some COM wrappers of an interface I don't know.
That's what I'm looking for, the appropriate interface to communicate through.
Bogdan.

The return type for Document.InvokeScript is object. May be you should step through the code in the debugger and inspect what the return value contains.
|
|
|
|

I tried that actually.
In a script block in the head of the HTML doc:
function f() { return [1,2]; }
In the C# code:
var list = browser.Document.InvokeScript("f");
ToString();
Alas, list was null!

Almost certainly IDispatch.

string str="select * from Furn_Info where Time >= '"+from+"' and Time <= '"+to+"'";
Although you should think about parameterising the 'from' and 'to' rather than building a string with them.

As Rob said, avoid using strings for dates, it only yields problems when you move to a PC with a different datetime formatting. Store real dates and times and datetimes in your database, not strings, and use parameterized SQL, which accepts date/datetime values directly instead of strings.
And please use PRE tags to show us your code.

private long bytesUploaded;
public long BytesUploaded
{
get { return bytesUploaded; }
set
{
bytesUploaded = value;
this.Dispatcher.BeginInvoke(delegate()
{
if (PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs("BytesUploaded"));
});
}
}

Too slow..

keeps throwing
-- line 10 col 1: VB does not support anonymous methods/lambda expressions with a statement body
thanks

I guess you have to implement this part in a different way then 
|
|
|
|
|

here is how you convert it
Private bytesUploaded As Long
Public Property BytesUploaded() As Long
Get
Return bytesUploaded
End Get
Set
bytesUploaded = value
Me.Dispatcher.BeginInvoke(Function() Do
If PropertyChanged <> Nothing Then
PropertyChanged(Me, New PropertyChangedEventArgs("BytesUploaded"))
End If
End Function)
End Set
End Property
and here is the Best Site for Converting

Hello and thanks for your reply
This lambada expression (do) is killing me
here is what i got so far
Private m_bytesUploaded As Long
Public Property BytesUploaded() As Long
Get
Return bytesUploaded
End Get
Set(ByVal value As Long)
Me.Dispatcher.BeginInvoke(Function() do(If PropertyChanged <> Nothing Then PropertyChanged(Me, New PropertyChangedEventArgs("BytesUploaded"))End If)) End Function)
End Set
End Property
Please help

You've been told already to please put your code in pre tags, it makes it much more readable.

webspeed wrote: If PropertyChanged <> Nothing Then PropertyChanged(Me, New PropertyChangedEventArgs("BytesUploaded"))End If
For a start, your code is easier to read in pre tags. As for your problem, you could replace that if-clause with a simple RaiseEvent EventName(EventArg1, EventArg2)

Hi Experts
I Have a Window Application in .net 2.0 and sql server 2005.

the person can close application from window tasklist.
then how i can solve this problem.
Thank U

In the login form itself, attach an handler for Applciation.Exit event. When you quit the applcation, from any form and through Task manager as well, this event will be fired. There you can set the flag to zero again.
Although you wont be able to do much about shut down though. Hence if the last login of the user was some X - minutes before, let the user login. Also, in this case, you will need to update the database with user's login details at regular intervals to handle following case:
Say if a user opened your application and has not done anything for 30 min. And you have set that X minutes as 15, then his connection is gone. So you will need to regularly update the database, maybe on another thread, that user has not closed the application yet and is doing something.

Hello,
I have an app that use an excel component(ocxt.com). This component have a strange behavior, which I reproduced it with Interop.Excel.
Bellow is the functions with I open and close an excel file programatically:
private ApplicationClass app = null;
private Workbook book = null;
private Worksheet sheet = null;
...
private void openExcel(string fileName)
{
if (app != null)
closeExcel();
app = new ApplicationClass();
app.Visible = false;
app.ScreenUpdating = false;
app.DisplayAlerts = false;
book = app.Workbooks.Open(fileName, Missing.Value, Missing.Value, Missing.Value,
Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value,
Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value,
Missing.Value);
sheet = (Worksheet)book.Sheets[1];
}
void closeExcel()
{
if (sheet != null)
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(sheet);
sheet = null;
}
if (book != null)
{
book.Close(false, Missing.Value, Missing.Value);
System.Runtime.InteropServices.Marshal.ReleaseComObject(book);
book = null;
}
if (app != null)
{
app.Quit();
System.Runtime.InteropServices.Marshal.ReleaseComObject(app);
}
app = null;
GC.Collect();
}
If I have 2 files: 1.xls and 2.xls and 1.xls I always open with .net code, and 2.xls double clicking it. There is 2 undesired (for me) behaviors:
1. If I open first by code file 1.xls, and then try to open 2.xls from Windows Explorer, 2.xls doesn't open. It only open an inactive Excel.
2. When I close by code 1.xls, it close 2.xls too.
What I do wrong?
Thank you.
