There can be two ways for this
1: Client Server, if u want someone to administor the system u can create a server application that will be on the admins machine and the client on other machines which the users will use.
2: A simple application can also do this,
just start a thread when the user logs in and break the thread
when the time reaches 1 hr and then u can block keyboard and the mouse so that the user cannot access anything or u can lock the computer with the admin rights so the user cannot access anything.
Hope this idea works for u
Regards,
Pramod

So you dont' want to write the program? You only want someone else to do the job for you, for free? Then you lack some understanding of how the world works.
This is a forum for programmers. If you have problems with programming there are a lot of people here that are happy to help you.
If you want someone else to do a job for you, put up a proper proposal for it, including a specification and what you are willing to pay for it.

a basic version would be:
string Password;
string Username;
///WHEN THE USER PRESSES OK///
{
if (tbUsername.Text == Username && tbPassword.Text == Password)
{
this.Close() //close the password entry form
form1.Enabled = true; //assuming the main form is form1
}
else label1.Text = "Username / Password Combination does not match";
}
you cannot really copy and paste this, but thats just lazy anyway
It should give you an idea of the structure you need to use for your program

What do you mean by locking the file?
If you mean that you lock it as you open it, simply close it.

As I see the file stream remains open .
You may copy the image into MemoryStream, then close FileStream .After this you will be able to delete the file and play with the image as you want.

This code snippet reads image file, show it in PictureBox then delete image file from the disk.
<br />
try<br />
{<br />
MemoryStream ms = null;<br />
FileInfo fi = new FileInfo(textBoxFilePathName.Text);<br />
byte [] buffer = new byte[fi.Length];<br />
<br />
using( FileStream stream = File.Open(fi.FullName, FileMode.Open) )<br />
{<br />
stream.Read( buffer, 0, (int)fi.Length );<br />
ms = new MemoryStream(buffer);<br />
}<br />
<br />
Image img = Image.FromStream(ms);<br />
pictureBox1.Image = img;<br />
<br />
File.Delete( textBoxFilePathName.Text );<br />
<br />
ms.Close();<br />
}<br />
catch (Exception e1)<br />
{<br />
MessageBox.Show( e1.Message );<br />
}<br />

If you load an image from a file, the file remains locked until you call Dispose on the image object.

Hey, howzit, anyone know a good place to get good FREE C# eBooks?

If it is a valid free eBook then you can link a URL to it. We don't condone the distribution of copyrighted material. Someone had to write that book and its sales put food on that author's table and a roof over their head. The bottom line is that distributing copyrighted material without the creators consent is theft.

I dont know of e-books as such, but there are many good reference sites such as Coding4Fun at http://msdn.com/coding4fun - it contains tutorials to make sample applications ranging from a LCD driver to a GPS-Wired application.

can somebody give a simple login validation program, i'm a newbie and i just need it for a refernece.thank you!
|
|
|
|

it's very simple
just get the text values of the textboxes that u
have used to accept the username and password and
then check those values with the valid username and password
if they match then the user is allowed to login
else the error message is displayed.

I am having a problem here with my project development. I would be glad if someone can help me out with this. Here comes.
I am trying to look for a way to find back the reference of a created object. Its something like vb6 callbyname but even using callbyname, i still need to have the reference of the object before i can use the callbyname.
Thanks.

I have something like the below code which might be reasonable to be in this way when there is just a 1,2 class and 1,2 property. But now i am having like 10++ different classed with each class having dozens of properties that i need to get and return the value which the name i can only know when its running coz its classname/propname is from a database table.
*********************************************
Select Case ClassName
Case "Class1"
Select Case PropName
Case "Prop1"
Return clsObj1.Prop1
Case "Prop2"
Return clsObj1.Prop1
End Select
Case "Class2"
Select Case Key
Case "Prop1"
Return clsObj2.Prop1
Case "Prop2"
Return clsObj2.Prop1
End Select
End Select
*********************************************
I was thinking to do something like
*********************************************
Select Case ClassName
Case "Class1"
return myType.InvokeMembers(PropName, Binding.GetProperty, clsObj1, nothing)
Case "Class2"
return myType.InvokeMembers(PropName, Binding.GetProperty, clsObj2, nothing)
End Select
*********************************************
This actually works but only problem is i still need to do this numerous time for each object. Is there somewhat a way to get back the reference of created object by name/type of the object so i do not need to code like this.
Thanks for ur reply.
