I don't have access to the client machines to find that out. What would change the value, wouldn't the OS create that value and leave it as it is ?

Christian,
I'm not sure what would change it, but it is possible via the .NET framework to change the Creation Date for a file or directory. I do a process at work where I have to move files and folders manually and I have to manually reset the file creation data. I'll admit that it is rare that needs to be done, but it is possible and does happen.
File.SetCreationTime();
So I wouldn't assume that your code is wrong just yet. Talk to that client first.

They may have caught a virus joggling with their system time.
.Net BCL wraps the standard Win32 routines for I/O so this error shouldn't really be .Net specific.

But Christian, is this the best method for checking the demo expiration when creation date can be altered ? I am just wondering.

There's not much you can do.
Even totally stupid noob can change their system time, so your best chance is storing a file on a clients machine with some kind of time-mark. Some sorta hidden system file stored somewhere deeeeep containing time-mark acquired from the internets is the best way I can think off right now.

i have used mltiple regression for crime forecasting, i know all the formulas to used but i m confused for forecasting formula...
Yt+1= b0+b1(Xt+1)
where does i get the value for thsi Xt+1??
can any one help or can provide me a code in C# for forecasting of crime??

This is not really a C# question, it's a question for people who know about crime forecasting.

Todays forecast is for some minor fraud in the financial districts with late afternoon muggings rolling up from the poorer areas. In commercial centers managers can expect some isolated violent acts as they ask their staff to work back on the weekend.
Back to you Christian...

My guess is the "t+1" part is a subscript that stands for "the next time unit". So Yt+1 and Xt+1 are the Y and X values at time t+1.

 How can I convert the OLE Object(byte array) from db1(my Access database) into a c# Bitmap object?
The Ole Object is a jpeg.
Source Code:
byte[] pictureData = <<...Ole Object...>><br />
int offsetValue = 78;<br />
Stream stream = new MemoryStream();<br />
stream.Write(pictureData, offsetValue, pictureData.Length - offsetValue);<br />
Bitmap bitmap = new Bitmap(stream);
Notes:
I have tried an offset value of 0-pictureData.Length.
I get an ArgumentException with message "Parameter is not valid." when instantiating bitmap object.
Thanks in advance

You shouldn't need any offset. If it doesn't work with an offset of 0, your data is probably bad.

Keep in mind also that the call stream.Write puts the stream position at EOF. So when you then pass the stream to create your new bitmap, its at the end of the stream and thus nothing to write.
Just because we can; does not mean we should.

I set stream.Position = 0.
Unfortunately, I still get the same ArgumentException.
Thanks in advance

A little searching finds that you should pass your byte array "pictureData" to the constructor for the MemoryStream. Then pass the stream to the Bitmap constructor.
byte[] pictureData = <<...Ole Object...>>
Stream stream = new MemoryStream(pictureData, 0, pictureData.length);
Bitmap bitmap = new Bitmap(stream);

Ah yes, string concatenation. Could someone please tell me what year it is? I'm sure I must have the wrong calendar.
Dear joynee, you might want to do some research on something called "SQL injection".

Well in 2008 if someone suggests you research something the obvious thing to do is type it into the Google keyword search input and click the search button. Then you attempt to locate a result that seems to provide a description of the item and read it.
However I can see how that might seem counter intuitive to posting a question in a forum, wait, no actually I can't.

Hi
i found in your code , this code snippet
//Get the values stored in the text boxes
txtDivision = gvTaskNewRow[0].ToString();
txtSegment = gvTaskNewRow[1].ToString();
txtDetail = gvTaskNewRow[2].ToString();
txtFuntion = gvTaskNewRow[3].ToString();
txtDescription = gvTaskNewRow[4].ToString();
txtTask = gvTaskNewRow[5].ToString();
txtCounty = gvTaskNewRow[6].ToString();
txtHighway = gvTaskNewRow[7].ToString();
please check is it correct?
i think that should be like this
//Get the values stored in the text boxes
txtDivision.Text = gvTaskNewRow[0].ToString();
---
thanks

No, his code is correct. You don't need to set the .Text property on a string. He prefixed the variables like it was a text box, but they were actually strings.

Hey guys
im trying to hide an image object (blob field) on a crystal report at runtime. the user will check a checkbox to either display or hide the object.
ive been battling with this for days...
i added a formula to the report in the designer as "False" so if i dont change this property at runtime is shouldnt show at runtime? correct? i assign the formula to the blob object.
what ive done in the code is i get the formulas collection object from the report then instantiate a formula field from this collection. i then assign formulaField.Text = checkbox.checked.ToString()
but the doesnt work 
any suggestions?

Hi
Does anyone know how to prevent a user from moving a ToolStrip from one ToolStripContainer into another? The scenario is that I have two non-TopLevel forms on a form, both have a ToolStripContainer and each ToolStripContainer has one ToolStrip. I am able, by default, to drag the ToolStrip from one ToolStripContainer into the other ToolStripContainer.
I'm pretty surprised that this is default behaviour and that there doesn't appear to be a simple 'AllowToolStripToChangeContainers' boolean to stop this happening.
The only 'solution' to this I could find on the net (after almost a day of trawling) was to trap the ControlAdded event on the ToolStripPanel and if the ToolStrip being added doesn't belong (originally) to that ToolStripPanel, then remove it and add it back to its original ToolStripPanel.
This 'works' in so much as it works, but there is a very annoying flicker and mouse judder when the ToolStrip is immediately removed then added.
I'd really appreciate any help
Thanks
Rob
