1 - Do you mean C# code, in a client side app, or javascript through a web app ? The former may be possible.

hi,
My problem is that my boss told me he didn't want to everytime add a new row to datagridview he must provide new values for new row's cell. Actually. in an added row, only one or two cell need changing values, others are unchangeable. He did want to copy an existing row and paste as new row as well as change the needed values without appearing errors
I tried to use getClipboardContent() method to manually add values of an existing row to a new row but its not working. I think everybody here could help me solve this by showing me how to copy a gridview row and paste as a new row without errors or suggest me a new way to solve this. Thanks in advance
[my code]
string[] str;<br />
private void copyToolStripMenuItem_Click(object sender, EventArgs e)<br />
{<br />
DataObject obj = dataGridView1.GetClipboardContent();<br />
str = obj.GetText(TextDataFormat.CommaSeparatedValue).Substring(1).Split(',');<br />
}<br />
<br />
private void pasteToolStripMenuItem_Click(object sender, EventArgs e)<br />
{<br />
try<br />
{<br />
DataGridViewRow dgvRow = dataGridView1.Rows[0];<br />
for (int i = 1; i < str.GetLength(0); i++)<br />
dgvRow.Cells[i].Value = str[i];<br />
dataGridView1.Rows.Add(dgvRow);<br />
}<br />
catch (Exception ex)<br />
{<br />
MessageBox.Show(ex.Message);<br />
}<br />
}
It seem to be a solution or an answer.

I want to append two or more WMV Files in C#... How can i do that????

Google the WMV file format. You'll need to extract the data from both files and append them together with a new WMV header.

hi
i have an app that work with Sql server 2005 Database,for insert to it i used Stored Procedure as "sp_AddToPersons" and use this code to insert action :
SqlConnection con = new SqlConnection(Properties.Settings.Default.ExpressDBConnectionString);<br />
SqlCommand cmdInsert = new SqlCommand();<br />
cmdInsert.CommandType = CommandType.StoredProcedure;<br />
cmdInsert.CommandText = "sp_AddToPersons";<br />
cmdInsert.Connection = con;<br />
<br />
SqlParameter p1 = new SqlParameter("@personName", this.txt_name.Text);<br />
SqlParameter p2 = new SqlParameter("@personFamily", this.txt_family.Text);<br />
SqlParameter p3 = new SqlParameter("@personTel", this.txt_tel.Text);<br />
SqlParameter p4 = new SqlParameter("@personAddress", this.txt_address.Text);<br />
<br />
cmdInsert.Parameters.Add(p1);<br />
cmdInsert.Parameters.Add(p2);<br />
cmdInsert.Parameters.Add(p3);<br />
cmdInsert.Parameters.Add(p4);<br />
<br />
try<br />
{<br />
if (con.State == ConnectionState.Closed)<br />
con.Open();<br />
<br />
cmdInsert.ExecuteNonQuery(); <br />
}<br />
catch (SqlException se)<br />
{<br />
MessageBox.Show(se.ToString());<br />
}<br />
finally<br />
{<br />
if (con.State == ConnectionState.Open)<br />
con.Close();<br />
cmdInsert.Dispose();<br />
}
but the table in my database was not update and don't insert to it, how to solve my problem ?

I don't see anything obviously wrong with that code. What about the code of the stored procedure?
Also, you should avoid naming stored procedures starting with "sp". This is because SQL Server has a number of stored procedures beginning with sp and if you call one it will look in the master database first and might ignore your stored procedure. At least, that was the case with previous versions of SQL Server.

Actually "sp" works fine, but "sp_" is the special prefix that is used for system procedures. Starting a procedure name with "sp_" does not only risk a name conflict with the system procedures, it will also prevent caching of the execution plan for the procedure. The database looks for a cached execution plan for the procedure in the master database, and as it doesn't find it there, it will always be recompiled, eventhough there might be a cached execution plan in your database.

I'm using FileSystemWatcher class to be notified upon any change in the file system of my server. But I wonder how I can obtain the information about the user that made the change. Any idea?
|
|
|
|
|
You don't. The FSW doesn't supply that kind of information.

In a WinForm if you create different BindingSources based on related tables in a DataSet, each time you create a new row in the child BindingSources the relationship key(s) value(s) are automatically entered in the child rows. This works really good.
My problem is I would like to be able to edit the key(s) in the master row.
If I do this then the child rows have no values created for the key(s) they take the value of null.
Is there a way to change the behaviour of the child BindingSources for them to take the new key(s) value(s)?
Is this even possible?
Thanks in advance for any ideas I am running out fast!

|
|
Hopefull that this helps someone in the future, all I had to do is EndEdit() on the master BindingSource!
A bit stupid from my part or was I

I'm thinking ahead, and wonder if anyone knows how a Type property is handled by its designers/typeconverters (if any)? What I'm hoping is that the designers/typeconverters for a Type property will allow entering the String class name of the type, and translate that to an underlying type field, f_MyType:
protected internal Type f_MyType = null;
public Type MyType
{
get
{
return f_MyType;
}
set
{
f_MyType = value;
}
}
TIA,
mike

Never tried it. I would suggest trying it real quick with a PropertyGrid. If it doesn't work, it shouldn't be too tough to write a custom type converter for that. I'm guessing it won't work, but shouldn't take much to test that.
|
|
|
|
|
Actually, I'd be tempted to write a type converter and maybe a UITypeEditor implementation that shows possible types to choose from.

Do you want to generate devanagri script numbers like: ०१२३४५६७८९
If Yes read on:
You can declare chars with the appropriate unicode and then do a ToString() to get the number in the desired format:
//Following will return the Devanagri Font '2'.
char HindiTwo = '\u0969';
HindiTwo.ToString();
The Unicode for the devanagri fonts 0 to 9 is '\u0967' to '\u096F'

thx alot,
that what i wanted ...and that was the only way to use unicode instead depend on the enviroment culture,but may be the only problem we cannot parse that unicode as number,
but anyway it will be appear as i want

I am making a custom host designer[^] and I am having a problem with my selection band updating. When I change the size of an item that is selected in my custom host designer fails to update the selection band. The control itself has a larger size but the selection band doesn't update to the larger size until I unselect the control and reselect it again.
