hi to all,
i am working with c# win application.
i want to copy a file from a server on the local machine.
the path to my file is "http://server/Dir1/myfile.doc".
before doing the copy, i need to verify if the file on the server has recent date than the file on the local machine. if yes i want to make the copy and if not i do nothing
any suggestions or code sample
best regards and thanks in advance

If you convert each segment of the date into a string, and check each segment in order, so:
if (server.year > local.year)
if (server.month > local.month)
if (server.day > local.day)
etc
- I am not sure on the datetime conversion functions, but there will be a way to split it up into segments with normal string functions and then convert them to int32's

Hey howzit,
I got a project off the net and I am trying to compile it. It gives me this error message:
"Visual Studio cannot start debugging because the debug target 'C:\.....\bin\Debug\xxx.exe' is missing. Please build the project and retry, or set the OutputPath and AssemblyName properties appropriately to point at the correct location for the target assembly."
So I built it first and then ran it. Can someone explain why one has to built and then run some apps and others work when you press run right away?

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.
