You can not. This is a special key combination interrupted and handled by Windows.

You'd probably have to use a hook. Hook the keyboard, and see if you can cancel the message. Although this is not advisable, unless you'r making some kind of kiosk thing. There are articles here on how to hook the keyboard and mouse and whatnot.

You do that through the database.

is there a way to call thread.join to thread from the threadpool?
|
|
|
|

If you want to synchronize one of your threads with a queued worker item, I would suggest
you use an AutoResetEvent or ManualResetEvent object; the worker item could call its Set()
method, the interested thread could use its WaitOne().

Hi,
I have created a window application. I have to provide security to it. I have to provide a login form with username and password. The username and password are present in the database. When i click the login button it should compare the username and password entered in the form with that in database and give access to the Window application that i first created. How to do it.
Please help

You just take the username and password from the windows form, have them be in the where clause of your query, if the query returns 1 row, then you let them log in. Simple enough.

I am writing a program that stores date, as fixed width data. The record is supposed to be 532 characters wrong. When I do the getRecordLength method it says that the record is 548 characters wrong. I looked at the file and its adding a strange character ( [], (, #, $, etc...) to each thing im writing. Why is it adding this and how do i get rid of this.
Thanks.

Because your name is Kyle.
Could you post a small section of the code that is performing the write?
|
|
|
|

this is the code
clsContact myData = new clsContact();
string Filename = "Employee.dat";
int flag;
string State = cboState.Text;
string Country = cboCountry.Text;
string Birthday = txtBdayMonth.Text + '/' + txtBdayDay.Text + '/' + txtBdayYear.Text;
string Anniversary = txtAnnMonth.Text + '/' + txtAnnDay.Text + '/' + txtAnnYear.Text;
string HomePhone = txtHAreaCode.Text + '-' + txtHPrefix.Text + '-' + txtHLast.Text;
string CellPhone = txtCAreaCode.Text + '-' + txtCPrefix.Text + '-' + txtCLast.Text;
string EmployeePictureFile = txtLName.Text + txtFName.Text + ".jpg";
myData.FirstName = txtFName.Text;
myData.LastName = txtLName.Text;
myData.MI = txtMI.Text;
myData.SSN = txtSSN.Text;
myData.AddressLine1 = txtAddressLine1.Text;
myData.AddressLine2 = txtAddressLine2.Text;
myData.Zip = txtZip.Text;
myData.OfficeExtension = txtOfficeExt.Text;
myData.Email = txtEmail.Text;
myData.Spouse = txtSpouse.Text;
myData.Department = cboDepartment.Text;
myData.State = cboState.Text;
myData.Country = cboCountry.Text;
myData.City = txtCity.Text;
myData.Birthday = Birthday;
myData.Anniversary = Anniversary;
myData.HomePhoneNumber = HomePhone;
myData.CellPhoneNumber = CellPhone;
myData.EmployeePictureFile = EmployeePictureFile;
BinaryWriter bw = null;
if (!validation())
{
return;
}
myData.FileName = Filename;
flag = myData.Create(Filename);
if (flag == 0) //An error
{
return;
}
{
{
try
{
int recs = (int)myData.getRecordCount();
//getInputValues();
myData.WriteOneRecord(recs);
}
catch (Exception ex)
{
MessageBox.Show("Error saving contact" + contact.FileName + ex.Message);
}
finally
{
if (bw != null)
{
bw.Close();
}
}
lstContacts.Items.Add(myData.LastName + "\t" + myData.FirstName);
contact = null;
}
}
}
and its calling these methods from a class
public long getRecordCount()
{
long records = 0;
long remainder;
try
{
if (myFile != null)
{
// Position the file pointer
records = myFile.Seek(0, SeekOrigin.End);
}
}
catch (IOException ex)
{
errorMessage = ex.Message;
return 0;
}
// See if there is a partial record
remainder = records % RECORDSIZE;
// Calculate the records
records = records / RECORDSIZE;
// If there was a partial record...
if (remainder > 0)
// ...up the counter to account for it.
records++;
return records;
}
and
public int WriteOneRecord(int num)
{
int errorFlag = 1;
try
{
if (myFile != null && bw != null)
{
//Postions the file pointer
myFile.Seek(num * RECORDSIZE, SeekOrigin.Begin);
bw.Write(LastName);
bw.Write(FirstName);
bw.Write(MI);
bw.Write(SSN);
bw.Write(AddressLine1);
bw.Write(AddressLine2);
bw.Write(City);
bw.Write(State);
bw.Write(Country);
bw.Write(Zip);
bw.Write(HomePhoneNumber);
bw.Write(CellPhoneNumber);
bw.Write(OfficeExtension);
bw.Write(Department);
bw.Write(Email);
bw.Write(Spouse);
bw.Write(Birthday);
bw.Write(Anniversary);
bw.Write(EmployeePictureFile);
}
}
catch (IOException ex)
{
errorMessage = ex.Message; //In case they want to view it
errorFlag = 0;
}
return errorFlag;
}
Thanks for the help in advance

I guess from the code, your thing would be much easier to handle as a SQL (or simply a Database) task. Still, I have question: Why is it important the size you stated in your 1st post?
to avoid strange chars:
you can use streamwriter instead of binarywriter with proper encoding (eg.: Encoding.UTF-16 - as a parameter-) if you expect other than eng. characters.
cheers, geri

Its for a school project, we have to use a text file, using a fixed witdth. And we have to use binary.
Kyle Maldonado

still don't understand why to use a fixed size (do you mean fixed size, when you write fixed width?):
an idea to your code: it 's always useful to close your writer in a finally block like:
binarywriter.close();
|
|
|
|
|
When I say fixed size i mean that
NAMESIZE = 30
if (txtName.length < NAMESIZE)
{
txtName.PadRight(NAMESIZE).Substring(0,NAMESIZE);
}
so then all the records are the same size so its easier to pull data out.
(The above code was just written fast, may not be correct)
