First, this really belongs on the ASP.Net board, but I'll take a whack at it anyway...
I don't know your reasons for caring why/when an image doesn't load, so I'm not sure how useful I can be, but the image loads on the client. You could add attributes to the Image (or HtmlImage) control to execute javascript on a load failure (OnError I think), but that would only work in IE.
In general, could you not just check the image dimensions (still on the client side)? I think the width and height would be zero if the url was not available, and that should work on almost any browser.
Hope this helps.

Hi, all.
I'm a bit of a newbie to C# and .NET. I want to create an on-screen keyboard for a touchscreen. They keyboard itself is easy enough, but I'm not sure how to "stuff" the keystrokes into the keyboard buffer. There's probably a better way than "stuffing" to begin with...
I want to be able to pop up a keyboard, and have keystrokes entered into the control that had focus before the keyboard appeared.
Any suggestions, or pointers to useful articles would be appreciated.
Thanks.

Almost every tochscreen ive ever seen has come with onscreen keyboard software bundled in with them - is there some reason why that or a 3rd party app will not do (ie, is this a leaning excercise?)

That it a good point. I haven't received the monitor yet, and the product info doesn't say if it comes with a utility to do this. However, having said that, I'm using this in a machine automation application, and would still like to be able to customize the user interface... probably not possible with a third party tool.
So, if anyone knows how to do this, I'm still very interested.
Thanks.

Hi
I got following function. When I debug the code '"+Name+"' is
Name="System.Data.DataRowView".
Does anybody knows why?
private void menuItem1_Select(object sender, System.EventArgs e)
{
string Name = this.listBox1.SelectedItem.ToString();
OleDbConnection conn = new OleDbConnection(connString);
OleDbCommand dbCommand = new OleDbCommand("SELECT Beschreibung FROM tbl_T5 WHERE (Rechner = '"+Name+"')", conn);
conn.Open();
OleDbDataReader dbReader;
dbReader = dbCommand.ExecuteReader();
dbReader.Read();
if (dbReader.HasRows)
{
this.menuItem2.Text = dbReader["Beschreibung"].ToString();
}
dbReader.Close();
conn.Close();
}

That's quite easy:
Name is set at exactly one location, so the value you see is the result of this.listBox1.SelectedItem.ToString();.
That means the selected item in your listBox1 is a DataRowView. DataRowView doesn't have an overloaded ToString method, so you simply get the type name.
But what's the question? Obviously you expect Name to be something else. Could it be that you don't want one of listBox1's items?
Without further info we can only guess...

Try replace this.listBox1.SelectedItem.ToString(); by this.listBox1.SelectedItem.Text;
|
|
|
|
|
got it..
DataRowView dv =(DataRowView)this.listBox1.SelectedItem;
this.menuItem2.Text = dv["Beschreibung"].ToString();
Thank you

Hi,
Can I use c#.net to automate Outlook Express ?
Btw, are there any C# based MAPI for communicating with Outlook Express ?
Many Thanks
|
|
|
|
|
|
Thanks for ur reply.
So it means I need to access outlook express with MAPI ?
And do you know any c# based MAPI component or code reference for MAPI with outlook express ?
|
|
|
|
|
Automation does not work with Express. MS wants you to pay for Outlook to do automation.

Of course is XmlDocument.LoadXml() throwing an exception, because of all the ampersands in your string.
They must be escaped as &
Using LoadXml() in a try/catch is a way to check for proper XML.

hi mav,
it is not throwing error if i escaped with a single & if i use like &&&&&&&&&& then it is throwing error.
i think its not a good way, if i use try/catch to check.
please help with a solution.

Of course you have to escape every & as &.
If you do this, the xml string is correct and no exception is thrown.
AFAIK there's no ValidateXml method available, so trying to load the string and looking for an XmlException seems to be a reasonable way.

I've posted this in the database section and got no response, so I thought I'd try here...
I need to export the contents of an SQL2000 table to a flat dbf file without any user intervention - Ie I don;t want them to have to use Enterprise Manager
Any ideas out there ???
Tks

I have a bunch of librarys in C to manipulate dBase databases, I'm sure it could be ported to C#
