It would certainly keep me busy for 6 months. With all the other demands on your time in the final months of your Masters program, you should select the simplest project you can get away with. It has to comprise enough of a challenge to demonstrate your mastery of the subject of your degree, but it doesn't have to add anything to the store of human knowledge - that's for PhDs. Only you and your faculty advisor can decide what's adequate to meet the requirements for your degree, so I'd discuss it with him/her. I know from experience that it's very easy to pick a project that is far too hard to complete in the allotted time, and you really don't want to get into that boat.
Keep in mind that, if your school is doing its job properly, you're going to have to submit a project proposal, a schedule, a top level design, a detail design, monthly progress reports, a test plan, test reports, program documentation, and a final report. That's all on top of actually producing a product that works. They all take time that you'd rather spend coding, so please keep that in mind when selecting the scope of the project you propose. The details will kill you. Keep it simple, but make it comprehensive enough to make your advisor happy.
Good luck, and congratulations on making it this far!

Any body help me
I am new in wpf windows. I want to know a binding concept.
and advantage of the this concepts with example. Please give
good article URL
Please replay...
Thank you...

There's all sorts of good articles, and excellent books. The big difference in WPF is that you can set up a binding so that if your object changes, the UI is updated, and vice versa, with no plumbing code.

Hello guys.
I'm wonder about differences between VS2008 and VS2008 Express Edition !
Could you explain the most differences between them ?
Thank you

Hi ppl
Lets assume i have 2 forms. Activity is hide one and show another. Just vice-versa.
Now everytime I have to create new form for which i want to show. Is there anyway to detect which form is hide or which instance have already created??
Pls help me thanks

I dunno what you're doing but you can know forms hidden status through Visible property

No Xen. thats not im asking for. I know that property.
My ques is how to detect from programaticaly.
Lemme explain again..
2 forms. Default open form1. when i click a button in form1, it will hide
exm. form1 code
{
this.hide();
form2 frm2 = new form2;
frm2.show();
}
Then show form2. In that form when i click button then it will show form1 again.
Now my problem is for showing i have to create form1 instance.
exm. form2 code
{
this.hide();
form1 frm1 = new form1;
frm1.show();
}
I dont wanna create another instance of form1.
Any way to do it.
Thanks

make an object of Form1 in Form2
in form2
public form1 form1inst;
in form1
form2 f2 = new form2();
f2.form1inst = this;
this.hide();
f2.Show();

What Xmen suggests is your solution. Since form1 derives from the Form class, you can also use a Form variable instead of a form1 variable. Going a step further, you can store the reference in a Control variable:
public Form FormRef
form2.FormRef = form1
or
public Control ControlRef;
form2.ControlRef = form1;
Both of these options will not limit your from storing one type of form and will make your code more flexible.
Happy coding!
There cannot be a crisis today; my schedule is already full.

sorry i cant understand ur code 1st time
but i tried to apply and its not working.
Its a nice way.
Thanks

Forgive me if this is stupid, but can't you create both initially as hidden, then alternately show/hide them? I've never tried it, as I'm just trying to learn the language, but it seems that it ought to be possible.

I have a dataset that contains a query stateing the following:
select * from table where id = @id.
This query works fine. The problem I am having is that I have 2 Windows forms, Form1 contains a datagrid and Form2 contains the textboxes, comboboxes etc.
How can I double click on a record in the datagrid and then that record should populate form2?
I know it should be handled in the datagrid_doubleclick method but How can I let Form2 know that I have double clicked on id 1?

you'll setting dataSet public,when form2 load and for form2 data

Can you possibly give me an example of what you are saying?

use MouseDoubleClick instead...
Point p = dataGridView1.PointToClient(new Point(e.X, e.Y));
DataGridView.HitTestInfo tmp_hinfo = dataGridView1.HitTest(p.X, p.Y);
if (tmp_hinfo.RowIndex == -1 || tmp_hinfo.ColumnIndex == -1)
return;

what you can do is provide an overload constructor for the second form that takes a datarow as a parameter
<br />
public Form2(DataRow drow):this()<br />
{<br />
this.text1.text=drow["Name"].ToString();<br />
}<br />
and as to figuring out which data that has been selected just handle "CellDoubleClick" and/or "RowHeaderMouseDoubleClick" events and then send the datarow selected by using the selected row from the event handler argument. like in this code:
<br />
private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)<br />
{<br />
new Form2(dataGridView1.Rows[e.RowIndex].DataBoundItem).Show();<br />
}<br />
hope this does the trick for you

I need to convert a coded string back to its original ascii charcters in c#.
The string has been coded by a vb6 application that I dont have the encoding code for but I do have the decodeing code as detailed below.
Public Function QLDecryptPassword(ByVal strPassword As String) As String
Dim intCharCounter As Integer
Dim intCharASCII As Byte
Dim strDecryptedPassword As String
If (strPassword = vbNullString) Then Exit Function
intCharCounter = 1
For intCharCounter = 1 To Len(strPassword)
intCharASCII = Asc(Mid(strPassword, intCharCounter, 1))
intCharASCII = 255 - intCharASCII
strDecryptedPassword = strDecryptedPassword & Chr(intCharASCII)
Next
QLDecryptPassword = strDecryptedPassword
End Function
can someone please let me have the equivelent c# code.
I have had a go using byte, byte[], char[], int convert.toint16,32.........etc but I just cant seem to get there.
any help greatly appreciated.

The code makes very little sense to me, but you can get the ASCII encoding of a string easily: Encoding.ASCII.GetBytes("some string") gives a byte[] containing the ASCII values.

Hi,
the highest threshold you have to overcome is the fact that all .NET languages have strings consisting of Unicode characters which take 16-bit each.
Now your original decryption code is taking a series of (unsigned) bytes and complementing all the bits (that is what x=255-x basically does); BTW encryption would have to be identical to one undoes the other.
The first decision to make is whether you want to deal with your password as a string or as a byte array. The natural thing to do is a byte[], since it isn't really a string in the .NET sense nor in any other sense, it just accepts all possible bit patterns without giving them any particular meaning, i.e. it is just binary data, hence best represented by a byte[].
So it could be as simple as:
public void crypt(byte[] data) {
for(int i=0; i<data.length;>}
which modifies the array content in place, useful for both "encrypt" and "decrypt" (quotes due to the fact that it doesn't offer much protection against prying eyes).

Hi,
I see Luc has beaten me to it.
Chances are that the old programme represents the string as single bytes so you should read the encrypted password into a byte array and decrypting will then just be some simple arithmetic.
To turn the the byte array into a unicode string you will need to select the correct encoding. The obvious one to try is Encoding.ASCII but this won't work if your data has character codes above 127. Windows 1252 is a single byte encoding, "provided for compatability with legacy systems" and is most likely correct.
Alan.
Example code:
public string QLDecryptPassword(byte[] encryptedPwd) {
byte[] decodedBytes = new byte[encryptedPwd.Length];
for (int i = 0; i < encryptedPwd.Length; i++){
decodedBytes[i] = (byte)(255-encryptedPwd[i]);
}
Encoding coding = Encoding.GetEncoding(1252);
return coding.GetString(decodedBytes);
}

thank you for the prompt answers and code examples.
I now have a working decrypt function so i can start pulling my hair out (what little i have) on the next bit of the program..........
