There are converters which can reduce the amount of work required, but you must have a good knowledge of both C/C++ and C# to get the job done.

Hello. I have a listview where I load data from sql database. ListView has two columns (name, surname) where data is loaded. On the selectedindexchanged event, when an item from the listview is selected it gets the other data from the database, based on selection, and writes it to several textboxes... basicly a phonebook. If I select someone from the list the info is displayed in the txtboxes, but if i click smeone a second time i get an exception "NullRefferenceException" "Object reference not set to an instance of an object."
private void lvNameList_SelectedIndexChanged(object sender, EventArgs e)
{
ClearSearch();
select = "SELECT * FROM agenda_telefonica WHERE nume = '" + lvNameList.FocusedItem.Text + "' AND prenume = '" + lvNameList.FocusedItem.SubItems[1].Text + "'";
SqlDataReader dr = realSql.Select(select);
if (!dr.HasRows)
{
MessageBox.Show("Information not found", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
else
{
while (dr.Read())
{
tbName.Text = dr[1].ToString().Trim() + " " + dr[2].ToString().Trim();
tbPhoneNumber1.Text = dr[3].ToString().Trim();
tbPhoneNumber2.Text = dr[4].ToString().Trim();
tbPhoneNumber3.Text = dr[5].ToString().Trim();
tbFaxNumber.Text = dr[6].ToString().Trim();
tbEmail.Text = dr[7].ToString().Trim();
tbCompany.Text = dr[8].ToString().Trim();
tbService.Text = dr[9].ToString().Trim();
tbEquipment.Text = dr[10].ToString().Trim();
}
}
dr.Close();
realSql.Close();
}
}
The exception is raised the second time i click an item in the list and points to the select string. Does it have something to do with the FocusedItem?

Before doing anything else check the if the SelectedItems.Count property is > 0.

Thanks.

You are closing realSql which is not opened in the method you have posted. It could therefore be realSql (null after closing) that is causing the exception.

realSql is a dll refference to a sql class i've created. it has an select(string select) which open an sql connection then returns a datareader ("SqlDataReader dr = realSql.Select(select)"). So the realSql.Close() closes the connection opened by the Select() method.

i have to Make a GridView with print option (Inherit the GridView control and add a print method). The print button should print all the rows in the gridview. There should an option to print no of rows perpage.

When faced with a problem like this, you have to ask yourself a question.
"Am I so brilliant that I have thought of doing something so extraordinary that no one has thought of doing it before?"
In 999,999,999 cases out of 1,000,000,000 cases the answer is going to be NO.
If the answer is yes, ask here. In all other cases Google the bloody thing!!!

can you tell me that which type of quesiotns have to be asked here?
its a realy so pythetic answer.

The sort of questions that should be asked here are those concerning a piece of code that you have written, that is not working in the way you expect, or at all. This is CodeProject.
The important points to remember here are
a) code
b) you have written
There are so many solutions to this problem on the internet that people are reluctant to answer, because it is perceived (may not be true but it is perceived) that you are too lazy to either Google, or try for yourself.
Find something on the Internet that most nearly suits your situation and try to implement it. If you get stuck then or do not understand part of it then ask here with a code snippet that is relevant (properly formatted, of course) and any error messages.
For goodness sake Google for print datagrid c# or print datagridview c# whichever applies. Pick one and have a go.
All of this advice is free, there is no need to thank me!

Hi,
I want to decompile a CHM file (help file) and also be able to compile the generated files back to a CHM file again in C#.
I have tried to do this using Microsoft Html Help Workshop. I create a Process and decompile with hh.exe and it works fine. After that I create a Microsoft Html Help Workshop project file, and the project file works perfect if I compile in Microsoft Html Help Workshop. But if I create a Process in .Net and try to compile with hhc.exe I get a corrupt CHM file, it looks like a web page that not can be loaded. I got the same problem if I compile from command line -> hhc [project file].
HHC5013: Error:
runtime error R6002
- floating point not loaded
Is it possible to do this only in C#? Or anyone who knows what is wrong?
I have added Hh.exe and Hha.dll in my Path variable.
I am not sure where I shall post this question so I try here.
Best regards
Marc

Hello,
Digging up this post from 1000 years ago
I am experiencing the issue of R6002 floating point not loading while running hhc.exe from the command line.
Have you by any chance found how to solve this issue (and remember how?)
Thanks

How will I validate the text of email address. I am making a window application in c# .net, in the text box I want that the textbox of email contains the '@' without written @ it gives a messagebox that it is not valid email address.
thanx in advance

Use a regular expression. There are several examples of email validation on google - some more accurate than others, so take your time and read around the various implementations (i.e. look for ones that can handle more complex email addresses such as .museum addresses).

The best way of doing this is using Regex. Try the below code.
private void txtboxEmailAdd_Validating(object sender, CancelEventArgs e)
{
string pattern = @"^[a-z][a-z|0-9|]*([_][a-z|0-9]+)*
([.][a-z|0-9]+([_][a-z|0-9]+)*)?@[a-z][a-z|0-9|]*\.([a-z][a-z|0-9]*(\.[a-z][a-z|0-9]*)?)$";
System.Text.RegularExpressions.Match match =
Regex.Match(txtboxEmailAdd.Text.Trim(), pattern, RegexOptions.IgnoreCase);
if (match.Success || txtboxEmailAdd.Text == "")
return;
else
MessageBox.Show("Invalid Email Address" + "\r\n" + "Please enter Valid Email", "Invalid Email Error",MessageBoxButtons.OK, MessageBoxIcon.Error);
e.Cancel = false;
}
Excellence is doing ordinary things extraordinarily well.

Didn't read the question properly!
string s = "Hello@email.com";
if (s.IndexOf("@") <= 0)
{
MessageBox.Show("Not an EMAIL address");
}
This will report on @email.com and email.com, but not on a@email.com
