i use a method that looks like this
public bool upload(string fileName)
{
FileInfo fileInf = new FileInfo(fileName);
string uri = "ftp://" + FtpServerIP + "/" + fileInf.Name;
FtpWebRequest reqFTP;
reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + FtpServerIP + "/" + fileInf.Name));
reqFTP.Credentials = new NetworkCredential(FtpUserID, FtpPassword);
reqFTP.KeepAlive = false;
reqFTP.Method = WebRequestMethods.Ftp.UploadFile;
reqFTP.UseBinary = true;
reqFTP.ContentLength = fileInf.Length;
if (fileInf.Exists)
{
return false;
}
else
{
int buffLenght = 20482;
byte[] buff = new byte[buffLenght];
int contentLen;
FileStream fs = fileInf.OpenRead();
try
{
Stream strm = reqFTP.GetRequestStream();
contentLen = fs.Read(buff, 0, buffLenght);
while (contentLen != 0)
{
strm.Write(buff, 0, contentLen);
contentLen = fs.Read(buff, 0, buffLenght);
}
strm.Close();
fs.Close();
return true;
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "Upload Error");
}
}
return true;
}
how do i implement what u suggested correcly ?

Perhaps I'm misunderstanding. You have the file you are uploading, FileInfo fileInf = new FileInfo(fileName); What is the point it comparing the uploaded version of the same file?

|

Well i want to be sure that the upload was completed succesfully, later i am deleting the file from the harddrive, thats why I need to do the check.

Generally, I'd say if you got no exceptions, then it succeeded. Usually the simple solution is the one that works best.

This is just a quess, but maybe try doing a socket.Disconnect() first?

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
Kurt

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
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");
