So the "IF NOT EXISTS (SELECT * FROM StaffTrackingFTEData)" is not needed? The reason I put that in was to eliminate duplicates. What is they submitted several times. I don't want the same data in there several times.

It's not eliminating duplicates - it's just preventing you from having more than one row in the table.
If you want to prevent duplicates, then you'd need to add a WHERE clause to that test to check the columns which you don't want to duplicate.

take away IF NOT EXISTS (SELECT * FROM StaffTrackingFTEData) I get " Cannot insert the value NULL into column 'StaffTrackingID', table 'SP2010_EDCStaffing_AppDB.dbo.StaffTrackingFTEData'; column does not allow nulls. INSERT fails.

That just shows that you have an issue with the subquery that should provide the StaffTrackingID. The issue was previously hidden because the INSERT wasn't actually attempted.
On a different note: Adding @StaffTrackingID as output parameter doesn't serve a purpose.

command.Parameters.AddWithValue("@StaffTrackingID", SqlDbType.Int).Direction = ParameterDirection.Output;
If I didn't declare that variable it was giving me an error that I needed to declare it.

I updated my sql query and it is giving me this error: (Must declare the scalar variable "@StaffTrackingID")
protected void SubmitButton_Click(object sender, EventArgs e)
{
const string Query = "IF NOT EXISTS (SELECT StaffTrackingID, Period FROM StaffTrackingFTEData where StaffTrackingID = @StaffTrackingID and Period = @Period) INSERT INTO StaffTrackingFTEData ([StaffTrackingID], [EstimateHours], [EstimateFTE], [ActualHours], [ActualFTE],[Comment], [CommentBy], [Period]) VALUES ((Select StaffTracking.ID From StaffTracking where StaffTracking.CATWResourceName = @Name), @Estimatehours, @EstimateFTE, @ActualHours, @ActualFTE, @Comment, @CommentBy, @Period)";
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["SQLStaffingConn"].ConnectionString);
using (SqlCommand command = new SqlCommand(Query, conn))
{
conn.Open();
command.Parameters.AddWithValue("@StaffTrackingID", SqlDbType.Int).Direction = ParameterDirection.Output;

That's because you're not passing a parameter called @StaffTrackingID.
Try changing your query to:
const string Query = @"DECLARE @StaffTrackingID int;
SELECT @StaffTrackingID = ID FROM StaffTracking WHERE CATWResourceName = @Name;
If @@ROWCOUNT = 0 RAISERROR('No staff tracking record found for resource ''%s''.', 16, 1, @Name);
IF NOT EXISTS (SELECT 1 FROM StaffTrackingFTEData WHERE StaffTrackingID = @StaffTrackingID And Period = @Period)
INSERT INTO StaffTrackingFTEData ([StaffTrackingID], [EstimateHours], [EstimateFTE], [ActualHours], [ActualFTE],[Comment], [CommentBy], [Period])
VALUES (@StaffTrackingID, @Estimatehours, @EstimateFTE, @ActualHours, @ActualFTE, @Comment, @CommentBy, @Period)
";

That worked but if no record is found for someone can I just skip it and continue? Your revised sql does exactly what I wanted to do except it gives an error and the users wouldn't know what to do with it. The problem is that we have some employee that are suppliers and others direct and vise versa. this is what I am getting.
No staff tracking record found for resource 'ALISON GREEN'.
Cannot insert the value NULL into column 'StaffTrackingID', table 'SP2010_EDCStaffing_AppDB.dbo.StaffTrackingFTEData'; column does not allow nulls. INSERT fails.
The statement has been terminated.
The Field in StaffTracking to determine if a person is a direct or Supplier is PersonnelResourceType. I changed the above code to include in the where clause SELECT @StaffTrackingID = ID FROM StaffTracking WHERE CATWResourceName = @Name and PersonnelResourceType = 'Supplier'; but still getting that message.

Thanks that worked. Really appreciated it.
|
|

Don't Clear and re-Add the Parameters for each row; just set the Values.
|
|
|
|
|
Thanks. Just set the values beforehand?

No - create the SqlParameters just once, before the foreach-loop and capture them in variables. Then inside the foreach-loop assign new values to these instead of recreating new SqlParameters for each loop-iteration.

Can you provide a snippet of what you are talking about?
So this is not correct?

Hi, I'm having trouble with the following code which takes a file on my local hard drive and writes it to a Linux server via FTP. It works, however the permissions of the file after it has been written to the server is 000 and I would like permission set to 775. Any ideas? The source file on my local hard drive is first created with the StreamWriter object.
string fileUri = "ftp://" + serverAddressTextBox.Text + "/" + masterDirectoryFileName;
DeleteFileOnServer(fileUri);
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(fileUri);
request.Method = WebRequestMethods.Ftp.UploadFile;
request.Credentials = new NetworkCredential(ftpUserNameTextBox.Text, ftpPasswordTextBox.Text);
StreamReader sourceStream = new StreamReader(directoryPath + "\\" + masterDirectoryFileName);
byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
sourceStream.Close();
request.ContentLength = fileContents.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(fileContents, 0, fileContents.Length);
requestStream.Close();
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
richTextBox2.Text += "Upload File Complete, status {0}" + response.StatusDescription;
response.Close();
Thanks for any insight you can provide!

This project[^] may be of use. It has support for more FTP stuff than the .NET Framework.
I have used it successfully myself.

There is only problem which is about the input string was not in the correct format. I use a textbox1 which is for me to type a number in the string format as I store the string in a variable knn. Then I try to convert it to Int32 and store it in another variable wup. However, after I tried to run the program, the error of input string popped up and I really run out of idea on what to do next.
public void find() {
int a = 0;
int h = 0;
Int32 t = 1;
int f = 130;
int d = 230;
string knn;
Int32 wup = 0;
knn = textBox1.Text;
wup = Convert.ToInt32(knn);

If you enter a none-integer value in your TextBox, Convert.ToInt32 is going to fail. In cases of parsing values, you really should use the appropriate TryParse instead, so you would expect this to be something like
int value;
if (!int.TryParse(myStringValue, out value))
{
return;
}
|
|
|
|

I am still unsure about what you commented. So I just need to insert this chunk into my code? In addition, int value represents which variable of mine? I am actually quite new to programming so please help me.

Remove the lines
knn = textBox1.Text;
wup = Convert.ToInt32(knn); and replace with
if (!int.TryParse(textBox1.Text, out wup))
{
MessageBox.Show("Please enter an integer value");
return;
}
Some other points ... instead of using
textBox2.Text = "Index = " + Convert.ToString(t); you can use the built-in ToString() method e.g.
textBox2.Text = "Index = " + t.ToString(); or possibly even better
textBox2.Text = String.Format("Index = {0}", t);There is more tidying up you could do but I'll leave it there

hi
Does anyone experienced in the text-to-speech in C# WinForm ?
Is it possible to get a clue or direction ?
