Well I was just going to store the ints and ints, but yea it really depends on where the data is supposed to go..

And, how about using Mehdi Gholam's zippy implementation of JSON on steroids here on CP ? Over-kill ?

That's what it implies, and yes, I know that you don't need reflection for serialization.

Because the TS gave an example where he'd convert a small structure to a string and back. If he had asked how to store a class or a collection, I'd answered serialization.

I'm not familiar with the article, but it sounds like a viable alternative.

Typically the answer to this is if you want to store something in a human readable form. Object->string conversions are often part of file I/O. (This is what I'm using similar code for.) Or, for a web app, creating a POST request body, though there it might be better to use &x=42&y=72.

Hey guys,really need some serious help with my capcha code project.My caphca code variation is that it has to consist of a number pattern and the user has to input the missing number
For eg. 2,4,6__,10 (Fill in the missing code)
I already have the graphics class setup ,so just the code for randomly generating a number pattern itself.Please Help guys.I'm a beginner programer.Help much appreciated.

What sorts of pattern do you want?
Once you successfully answer that question (defining the pattern types that are valid) it should be trivial to write it in code.

Hi Guys!
I am trying to make one simple application where i want to have info from db(Damain Z)
example:
I am in Damain X where the tool will reside,i have a bridge domain Y and a domain Z where DB resides..
any clue how to solve this senario!!!

If these is no trust setup between Domain Z and Domain X, you're limited to using SQL Server accounts and SQL Authentication. The problem with this is maintaining the accounts on the SQL Server, seperate from everyones AD account.

Hi Guys,
I am having a problem here, please help.
I wanted to create an CAPTCHA image using text from SQL Database but now I don't know how to actually fit the get and fit the text in the image. I have already created the image but with automatically generated text using C# code.
I tested my program before, I got the image with the automatically generated text but now I dont get the other components like the textbox and botton for entering the text and validating it.
Please help!!! Thanks in advance!!!

Why? What you create will almost certainly not be as good or robust as those that are already available.
Have a look at ReCaptcha[^] - it's free, it's easy to use, and it helps digitise books that have failed OCR treatment.

Fixed - it's the damn link truncation bug again. If you highlight text and then paste a link for some reason the url gets truncated in proportion to the original text length. But only sometimes, and most links get straight through. I reported it a month or so ago...

Hi
For my assignment, I need to find out all rows that were newly added into the datagrid and add it to the database.
I have pasted my code below, getting error in setting dRow where it says index is out of range.. I thought the newly added row can be accessed thru the index. Please let me know how to access the cells in newly added row.
public partial class AllCustomer : Form
{
private int ii;
public AllCustomer()
{
InitializeComponent();
string strConnection = "Data Source=.;Initial Catalog=Company;Integrated Security=True";
SqlConnection sqlconn = new SqlConnection(strConnection);
DataSet ds = new DataSet();
string sqls = "select * from CustomerMaster";
SqlDataAdapter da = new SqlDataAdapter(sqls, sqlconn);
sqlconn.Open();
da.Fill(ds);
dataGridView1.DataSource = ds.Tables[0];
ii = dataGridView1.RowCount;
sqlconn.Close();
}
private void btn_Add_Click(object sender, EventArgs e)
{
string strConnection = "Data Source=.;Initial Catalog=Company;Integrated Security=True";
SqlConnection sqlconn = new SqlConnection(strConnection);
DataSet ds = new DataSet();
string sqls = "select * from CustomerMaster";
SqlDataAdapter da = new SqlDataAdapter(sqls, sqlconn);
SqlCommandBuilder cmdBldr = new SqlCommandBuilder(da);
sqlconn.Open();
da.Fill(ds);
dataGridView1.DataSource = ds.Tables[0];
for (int j = ii; j >= dataGridView1.RowCount; j++)
{
DataRow dRow = ds.Tables[0].NewRow();
dRow["cust_name"] = dataGridView1.Rows[j].Cells["cust_name"].Value.ToString();
dRow["cust_st_addr"] = dataGridView1.Rows[j].Cells["cust_st_addr"].Value.ToString();
dRow["cust_city_state_zip"] = dataGridView1.Rows[j].Cells["cust_city_state_zip"].Value.ToString();
dRow["cust_phone"] = dataGridView1.Rows[j].Cells["cust_phone"].Value.ToString();
dRow["cust_stat_cd"] = dataGridView1.Rows[j].Cells["cust_stat_cd"].Value.ToString();
dRow["cust_add_dt"] = "2011-10-14";
dRow["cust_updt_dt"] = "2011-10-15";
ds.Tables[0].Rows.Add(dRow);
}
da.Update(ds.Tables[0]);
}
}

this is wrong.
1) In the button add click event you load the data form the DB again. Without first adding stuff
2) ii has the value of Count . Lets say 5. That means dROW[4] maximum and you start with 5.
The list could go on.
All the best,
Dan

I've visual c# 2008 ,I wanna make an assembly program of 8086 microprocessor on it,, is it available ????
could u show me the steps ,,plz??? thanks

Uhhh.. you're either asking how to write an 8086 emulator or your looking to write an app in Intel Assembly Language. I really can't tell which.
In either case, the required discussion would fill entire books. WAY too much information for a couple of forum posts.

Here[^] is an article that seems to explain things rather well, I didn't test it however I do expect it to work properly, even with Visual Studio C++ Express. What it doesn't say is you will be getting some build errors, unless you move some switches away from their default values. Trial and error will be involved.
[ADDED]
ML.exe may already be present in C:\Program Files\Microsoft Visual Studio 9.0\VC\bin
Now how is this a C# question?

From what it sounds like, and I'm still wondering about it, he might be wanting to have some 8086 (why an old 8086, maybe meant 80x86) Assembly code get called from C#. Like Dave's post, who knows for sure.

Nah. Calling an assembly function is too easy: just call it like you would call a regular C/C++ function, i.e. using P/Invoke, and make sure to have the calling conventions declared correctly.
We'll know what he really wants tomorrow. Or later. Or not at all. Who knows?

It's pretty easy, too. But again, who knows what his real requirements are.
