Correct, you can't copy a locked file. No way around it.

Hey uh, i have a project and its considered as a thesis project in our school. My project is an automatic controlling model for monitoring and triggering.
A webcam or any camera will be attached to monitor object in a two dimensional frame with x and y axis. My problem here is, for initial run of the program(the camera is already in front of the frame) the camera will monitor if there is a change in the plane, like for instance the frame is a white board and I put a dot in the white board, the program would determine the coordinates of that dot(.) in the x and y axis of the plane in front of the camera. And once that coordinates is located, a pointer like a laser pointer attached to stepper or servo motor that is connected to the (parallel) port of the computer, will point to that coordinates computed by the program.
my specific problems are:
1. how would the program know the coordinates of the interrupting object?
2. how would the pointer that is attached to the stepper motor point the coordinates of the plane in front of the camera?
these are my major problems.
My adviser told me that the camera will be used as an actuating device. But I would ask for a better actuating device to monitor an interrupting object on the frame. Please do advise or help me I'm just a 4th year student and I don't even have a background of device interface programming, and I am also a beginner in C#.Net or VB.Net language please do help me. I can't graduate without this. Please

Sorry, but if this is above your technical skills, you shouldn't graduate - simply because you don't fulfill the requirements. (Or maybe the requirements are not appropriate. Don't know and don't care...). Do your homework!
This is not a free-of-charge coaching place!

hey sir uh, no offense please
but its not about the homework or unaccomplished material or something
maybe its not like your school but uh let me tell you that its not like any school in US that spoon feed students. I'm here in the Philippines and our school is a type of school that doesn't spoon feed students. It mean that, our challenge that is the point of our studies, just how we knew the language in C++ or Java is also the same. We were given a problem and they let us decide whatever we do just to show them that the program is working properly.
It is hard for me to use C or Java for that specific problem that is why we are obliged to study other language in just a short period of time. The strategy of our school is to guide the students only and this is not the same in US that trains even a simple logic to students.
What I'm trying to Please is Only a GUIDE and ADVISE.
Please if you don't like to help me or give me some guidance, please be advised to please don't comment anymore. You'll just waste you time.
What I'm seeking is help not a Sermon.
Thanks.

Read my image processing articles for ideas on how to look through a bitmap to work out if an area is black instead of white.

Hi,
I'm trying to do this and am wondering if it is possible.
I have a DataGridView control. I would like the ToolTip message to show some data (on the DataGridView itself) when the cursor is over that particular row in the control. If the cursor is out side the data rows but within the control (i.e. in the parts that have no data), I would like it to show another message.
I have tried this.
private void grid_CellMouseEnter(object sender, DataGridViewCellEventArgs e)
{
if (e.RowIndex != -1 && ds.Information.Rows[e.RowIndex]["Value"] != null)
{
this.grid.CurrentCell.ToolTipText = ds.Information.Rows[e.RowIndex]["Value"].ToString();
}
else
{
toolTip.Show("Right-click to display menu", this.grid);
}
}
What do I have to do to get it working?
Thanks.

Dlsoft (www.dlsoft.com) sells an adequate barcode tool. Their technical support is very helpful if you have problems.

in my application i have some 4-5 tabs. what i need is on a button click the tab containing the ACtiveX control should be selected and the shared screen should be shown. the problem comes when i click on the button the corresponding tab is shown but gives an error of InvalidStateException. Maybe the ActiveX control needs some time to load .... becz if i am putting a message box there it works fine.
is there some way in which i can wait or check until the control has been loaded.

i am unsing ADONET for my database. What's happening and how to solve it if i have error :
1.Database: Object reference not set to an instance of an object
2.Data type mismatch in criteria expression.
3.The field is too small to accept the amount of data you attempted to add. Try inserting or pasting less data
Thanks.

1 - fix your code. This means an object is null. Can't say more without seeing code
2 - fix your code. You're trying to compare objects of different types. Perhaps missing quotes from a string ?
3 - Fix your code, specifically make your code not accept data that's longer than the DB column will accept, or make the DB column bigger.

None of this makes any sense. All strings in C# are unicode. I think you need to post your code so we can see what you're doing wrong.

thanks Christian for ur attetion
i used the unicode for arabic letters my friend
here is my code
int Counter = 0;//looping throught the string
int CountAllLetter = 0;
int CountInFirst = 0;
int CountInMiddle = 0;
int CountInLast = 0;
//-------------------------------------
string Qurantext = " " + Txt_search.Text.ToString() + " ";
string LettertoUnicode = string.Empty;
//-------------------------------------
CharEnumerator charEnum = Qurantext.GetEnumerator();
while (charEnum.MoveNext())
{
LettertoUnicode = Convert.ToString(Qurantex[Counter]);
//here is my problem
stringletterunicode=@Cmbletters.SelectedValue.ToString();
if (LettertoUnicode == letterunicode)//"\u0645")
{
// To Increment the letter in all text
CountAllLetter++;
charEnum.MoveNext();
//Before the letter space
string checkfirst = Convert.ToString(Qurantext[Counter - 1]);
if (checkfirst == " ")
{
CountInFirst++;
}
//this string to check if the letter in the last word by checkin the next letter if it space
string checklast = Convert.ToString(Qurantext[Counter + 1]);
if (checklast == " ")
{
// To Increment the letter in the last
CountInLast++;
}
// in the middle
if (checkfirst != " " && checklast != " ")
{
CountInMiddle++;
}
}
Counter++;

What is Qurantext ? If it's a string, why not use the contains method to look for substrings ?
