Are you sure that you wrote that code? It looks like you copied and pasted it from somewhere, without even looking at it. What's the give-away, you may ask?

You are supposed to replace all those with actual E-Mail addresses, and your working SMTP server.

Isn't the MailMessage.To property, read-only? I don't think you can write
clife537 wrote: mail.To = "mail@mymail.com";
It would generate an error.
To add an email address to the MailMessage.To property, you'd have to write something like:
mail.To.Add("someone@somewhere.world");

Hi,
Does anyone know how the get/Pass the DBnull Value of an integer field from a typed dataset without getting an error?
Propertie Allow DBnull is true for my integer field.
Thx

I'm not quite sure I understand your question, but if I understand correctly, DBNull.Value, will give you a null value you can pass.

hi,
thx for u'r response. (i rather be polite thinking you're invention maybe exists.  )
Its a column from a typed dataset, which has no value entered by the user. so the value is DBnull. When getting my value to pass to a stored proc it results in an error.
Typed dataset DataSet1 with Table1 has 3 columns all integers with property allow DBnull
Gives a row Table1Row with fields Table1Row.ID1, Table1Row.ID2, Table1Row.ID3
when calling for example Table1Row.ID2 it gives an error.
In designtime the property Nullvalue also remains (throw exception) and cannot be modified. For string fields it's no problem.
Thx again.

What is the error message you are recieving?

The error message is :
The value for column 'ID2' in table 'Table1' is DBNull
|
|
|
|
|
Double check that the field ID2 does allow null values, that make sure that there isn't a exception thrown if there is a null value. Additionally, in your code, you can check the value before passing it, and if it is equal to DBNull then set the value to 0 instead of null.

Found something :
[^]
i need to check each field for null and pass null value myself. Seems very unlogic to me knowning that SQL servers allow DBnull values in tables.
Ex :
<br />
if(Table1Row.IsID2Null())<br />
ATDatabase.AddInParameter(updateCommand, "ID2", DbType.Int32, null);<br />
else<br />
ATDatabase.AddInParameter(updateCommand, "ID2", DbType.Int32, Table1Row.ID2);
Checking the auto generated code from the typed dataset:
[System.Diagnostics.DebuggerNonUserCodeAttribute()]<br />
public long ID2 {<br />
get {<br />
try {<br />
return ((long)(this[this.Table1.ID2Column]));<br />
}<br />
catch (System.InvalidCastException e) {<br />
throw new System.Data.StrongTypingException("The value for column \'ID2\' in table \'Table1\' is DBNull.", e);<br />
}<br />
}<br />
set {<br />
this[this.Table1.ID2Column] = value;<br />
}<br />
}
Cannot pass null value here...

IIRC a typed dataset generates 2 methods for you:
IsColumnNameNull()
SetColumnNameNull()

hello,
I'm working on a C# windows application. I've managed a connection with an MS Access Db, but I'm having a problem with retrieving a single cell from a table.
Can someone please post a sample statement of retrieving and converting it to string?
Thanks in advance.

Have a look into this simple example

Create a DataTable. Once you have established a connection, use a TableAdapter to fill the DataTable. Once you have done that, it's as simple as getting the data from a DataTable.

I've embedded a webbrowser control in a 3rd part application via their plug-in mechanism
The first time I set the documentText property on the webbrowser control nothing happens. The documentText property remains as "/0" and the browser doesn't update. On subsequent attempts when i set the value it works just fine, all updating occurs via the same code.
I found a single posting where someone was experiencing the same issues but no one had much advice.
Has anyone seen this behaviour before?
Thanks
Russell

Maybe. Try this rather than setting the documentText property:
browserCtrl.Navigate("about:blank");

Thanks mike,
That was one of the things i tried while getting this thing to work. There were a few people who reported that until the page navigated somewhere you couldn't set the document text property. I'd forgotten about that.
At least i now understand that the documenttext won't show the text you set it to until that text is loaded up in the browser so it makes sense that it would still be blank.
Is there a way to force the browser to render the text it's been given?

Not exactly sure what you mean by that but this has been working for me for several years now
browserCtrl.Navigate("about:blank");
string sHtml = "<html><body>No Document</body></html>";
Document.Write(sHtml);
This is in a User Control where also:
public HtmlDocument Document { get { return browserCtrl.Document; } }

Plz give me idea about how to run Multiple command in MS_DOS using C Sharp code.
for eg. using command prompt: telenet 10.0.1.15
login : snt
password : snt
execute more commands....
i use
System.Diagnostics.Process.Start ("cmd", @"/c telnet 10.0.1.15");
but how to again fire command for login, password and more...

I don't think you're going to be able to do it using Process.Start as you're simply launching another process - you need to have your own to send messages and listen for events etc.
For telnet, have a look at this[^]. I haven't tried it but it's open source so it should give you an idea at least by examining the source.
