How to change the name of the datagrid column thru programs?
For example.
in the table pmast, rcpno is the name of a field. But in the datagrid, I want to display the column heading as Receipt No.
The code is as follows :
Private Sub viewbtn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles viewbtn.Click
Dim strconv As New OleDb.OleDbConnection(ds)
disallbtn()
binddv = New OleDb.OleDbDataAdapter("select rcpno, rcpdt ,pname from pmast order by rcpno", strconv)
If Not oledv.Tables("pmast") Is Nothing Then
oledv.Tables("pmast").Clear()
End If
binddv.Fill(oledv, "pmast")
DataGridView1.DataSource = oledv.Tables("pmast")
DataGridView1.Show()
DataGridView1.Focus()
End Sub

|
|
Try this -
Dim myStyle As New DataGridTextBoxColumn
myStyle.MappingName = "Emp_name"
myStyle.HeaderText = "Employee Name"
|
|
|
|
|
Since your SQL code is in code use As clause in SQL with [receipt no] and modify your code to use Receipt no as the field name

Hi... Am new to .net here. Hope am posting the question under the right category... My requirement is as follows:
I have a gridview which is visible with an empty row on page load. It has four columns of which the first column is a text box item template. The rest 3 are bound fields. Now, when I enter a valid data in the text box(for eg, an employee ID)and hit the enter key, the rest of the fields must be bound to the grid. All four columns are available in a table in the back end. I have used a datatable and made the gridview datasource as the datatable. Am using a stored procedure to bind the data.. Using SQL Server 2008(.Net 3.5 framework). Kindly help... Im totally blank right now...

Following code is useful to you.
void dataGrid _EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
DataGridView dgr = (DataGridView)sender;
if (dgr.CurrentCell.ColumnIndex == 2)
{
if (e.Control is TextBox)
{
TextBox tb = e.Control as TextBox;
tb.KeyPress += new KeyPressEventHandler(tb_KeyPress);
}
}
}
void tb_KeyPress(object sender, KeyPressEventArgs e)
{
if (!(char.IsDigit(e.KeyChar)))
{
if (e.KeyChar == Keys.Enter)
{
e.Handled = true;
}
}
}

hi,
There isn't any option available to import mysql dump file directly to
sql server. Because the data exported by mysql as dump is not compatible
with sql server to restore at one go.
You need to use phpmyadmin or some other tool to export mysql database
(export as excel or some other format that is compatible in sql server),
instead of taking dump directly from command prompt.
And then try to restore it.
However, if you have to restore backup file of sql server into another
database (sql server to sql server) then it is absolutely possible in
C# using SQL SMO.
Find following link for the same.
http://www.geekpedia.com/tutorial180_Backup-and-restore-SQL-databases.html[^]
http://www.mssqltips.com/tip.asp?tip=1849[^]
And please use pre tag to format your code and mark your "Message Type" as "Question" not as "General".

we are using mysqlserver 2005 and sql yog for database management not sql server 2005
but the code which we are using is not working
|
|
|
|
|
string cmd = string.Format(@"-u{0} -p{1} -h{2} {3} <(4)", "dfs", "sf#", "localhost", '"' + temple1 + '"', "E:\\BackupMysql1\\temple.sql");
I think the first issue is in the bracket you are using for 4th argument.
Instead of () you need to use {}.
Along with it you need to change one more line as follows.
ProcessStartInfo proc = new ProcessStartInfo(@"[FullPath]\mysql.exe");
because it will find mysql.exe file only if you put it in windows directory along
with supporting files.
And that's it. I have tried the same at my local machine with the code you have
provided and changes I have suggested, and it's running fine.

Ok, I have found the problem and also resolution.
Consider following points in resolution.
1. Don't provide password when you are building arguments. You need to provide it later on
when you prompted for it.
2. you need to give filename as cmd.exe instead of mysql, because it will come under the
arguments.
For example, build your arguments as follows
string cmd = string.Format(@"C:\wamp\bin\mysql\mysql5.1.36\bin\mysql.exe -u {0} -p -h {1} {2} < {3}", "root", "localhost", "test123", @"C:\wamp\bin\mysql\mysql5.1.36\bin\wp.sql");
ProcessStartInfo proc = new ProcessStartInfo("cmd", @"/C " + cmd);
proc.UseShellExecute = false;
Process p = new Process();
p.StartInfo = proc;
p.Start();
p.WaitForExit();
See it I have not provided password. It should ask me for the password when I execute the process.
And that's it. It is now importing mysqldump file successfully.

hi sr159,
You are not reading my answer. Again running wrong command.
Just read my answer carefully. I have supplied mysql instead of cmd command.
Instead of below line...
string cmd = string.Format(@"C:\Program Files\MySQL\MySQL Server 5.0\bin\cmd.exe -u{0} -p -h{1} (2) < {3} ", "root", "localhost", '"' + database + '"', "E:\\BackupMysql1\\temple.sql");
Just use the line...
string cmd = string.Format(@"C:\Program Files\MySQL\MySQL Server 5.0\bin\mysql.exe -u{0} -p -h{1} (2) < {3} ", "root", "localhost", '"' + database + '"', "E:\\BackupMysql1\\temple.sql");
And now execute the command. And try to edit your question not re-post or posting totally new question as reply by changing the message type.

i changed cmd.exe to mysql.exe then also it is executing but not saving dump file to database using C#.
|
|
|
|
|
after running the processor which is taking the path is D:\the application folder name and not asking password.
|
|
|
|

problem solved now it is working thank you for all who replied to me

Thanks in advance.
how to convert a windows long path name to short pathname in VB.Net.
|
|
|
|
|
Find following code useful for the same.
[DllImport("kernel32.dll", CharSet = CharSet.Auto)]
public static extern int GetShortPathName(
[MarshalAs(UnmanagedType.LPTStr)]
string path,
[MarshalAs(UnmanagedType.LPTStr)]
StringBuilder shortPath,
int shortPathLength
);
public static void Main()
{
StringBuilder shortPath = new StringBuilder(255);
GetShortPathName(@"D:\My Temp\ResourseProvider\sql.txt", shortPath, shortPath.Capacity);
Console.WriteLine(shortPath.ToString());
}
The code is in C#, however you can do the same with syntactical changes in vb.net.

I dunno who downvoted you, but I ran your code and it returned a correct answer. I got
E:\MYTEMP~1\RESOUR~1\sql.txt
However, it will fail if the path does not exist. Try the API on an existing path, and it will work.
