close popup after response.end()

4-Apr-06 21:44

I don't know it if is what you really need... but try this.

private void mdi_Load(object sender, System.EventArgs e)
{
try
{
throw new Exception ( "Error" );
}
catch
{
this.Closing += new CancelEventHandler(mdi_Closing);
OnClosing( new System.ComponentModel.CancelEventArgs ( false ) );
}
}

private void mdi_Closing(object sender, CancelEventArgs e)
{
System.Windows.Forms.Application.Exit ();
}

Hope It works

Hi
You don't say how you are showing the form.

If you are showing it using ShowDialog, you can just set the DialogResult property:

private void Form2_Load(object sender, System.EventArgs e)
{
    try
    {
        ...
    }
    catch
    {
        DialogResult = DialogResult.Abort;
    }
}

Can anyone tell me how to gain control of the web page after response.end()? I am generating a dynamic excel sheet and to render it to the client I am using response..end , but I am left with a blank window. This is because the thread aborts after response.end and I have no control over the popup. Has anyone seen this problem with gmail tooo? Try downloading the attacment. This is the probelm I am facing too.
Any solution?

here is my code for download page:
private void Page_Load(object sender, System.EventArgs e)
{
Response.Clear();
Response.ClearHeaders();
Response.ContentType="application/octet-stream";
Response.AddHeader("Content-Disposition","attachment; filename=\"" +FileName + "\";");
Response.AddHeader("Content-Length",((byte[])Attachement).Length.ToString());
Response.WriteFile(FileName);
Response.Flush();
Response.Close();
}
if your window still keep opened, you can try to use hiden frame:
like this:[a href='download.aspx?file=xxxxx' target='hideframe']download[/a]
Hope this can help you.

Loading class objects from datasets

4-Apr-06 19:47

hi all,

My business layer contains 1 object per table in my
database. Object properties are the same as table fields.

I get a dataset with 1 row back from my database when I
instantiate my objects. Is there a way to load this dataset
into my object properties (fields)? without having to
traverse and match the nodes on the dataset to my properties?

this way, I can use the same method for all my objects AND
I dont have to worry about the function if I change my object
or table.

any ideas?

thanks

M

Hi
You could use reflection for this.

In a windows application(C#) I am working on,I have 5 threads accessing data from a table and running one after another.I want to lock data for each thread when it is accessing data ,so I have used "for update" in my select statement but it doesn't work.Every thread when accessing data sets one flag in the table so that other threads should not select this data again,but some times 2 or 3 threads access the same row .Any help to lock the rows please.
Thank you.

How draw formatted text in cell DataGrid

4-Apr-06 21:52

The time we have to did this, we have to create anhoter table in the database with information about the tables or rows locked.

I mean.

One Method to lock

Lock ( string TableName )

Lock ( int[] RowsIDs )

UnLock ( string TableName )

UnLock ( int[] RowsIDs )

Write this info in a table, and when the data is queried to the database do a Join with the rows of this table.

Also we add a delay of 5 minutes to set free the rows, because someone can forget the UnLock.

Is there any way to make property grid values color changed in some
cases based on certain scenarios. I only wanted to change right side
values of some grids in property grid. Is there is any way to do this
plz let me know it( whether it is reflection or any other thing ). Also
another issue to make property grid readonly which i dont think any
body know.

Thanx in advance..............

Ricardo Casquete4-Apr-06 21:55

You can.

There easier way in my opinion is to add the code for formating the cells in the Item_DataBound method.

In the Item and Alternate Item, do a loop to iterate for the cells of the Row and Set the Style you want

Drag and Drop any table to geenrate the SqlDataAdapter, Drag and drop the Grid and genereate the Item dataBound code...

and copy this

<br />
		private void Page_Load(object sender, System.EventArgs e)<br />
		{<br />
			this.sqlDataAdapter1.Fill ( this.dstCategories1 );<br />
			this.DataGrid1.DataBind();<br />
		}<br />
<br />
		private int i = 0;<br />
		private int j = 1;<br />
<br />
		private void DataGrid1_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)<br />
		{<br />
			if ( ( e.Item.ItemType == System.Web.UI.WebControls.ListItemType.Item ) || ( e.Item.ItemType == System.Web.UI.WebControls.ListItemType.AlternatingItem ) )<br />
			{<br />
				if ( i % 2 == 0 )<br />
				{<br />
					e.Item.Cells [ 0 ].BackColor = Color.Aqua;<br />
				}<br />
				if ( j % 2 == 0 )<br />
					e.Item.Cells [ 1 ].BackColor = Color.Red;<br />
				else<br />
					e.Item.Cells [ 2 ].BackColor = Color.Yellow;<br />
<br />
