GDI+ Image wont Show Properly

I got this simple GDI+ Code:

Bitmap image = new Bitmap(300, 50);
Graphics g = Graphics.FromImage(image);
g.FillRectangle(Brushes.White, 1F, 1F, 300F,50F);

Font font = new Font("Impact", 20, FontStyle.Regular);
g.DrawString("Saranghae", font, Brushes.Blue, new Point(10, 5));

image.Save(Response.OutputStream, System.Drawing.Imaging.ImageFormat.Gif);
image.Dispose();
g.Dispose();

But I got this output instead of an image

Subqueries

Hi guys,
I have three different queries and i would like to put them as one huge query.
This will reduce the number of times i make a connection to Sql Server and hence load
time on my page.
I have already managed to put two queries like:

SELECT COUNT(Cellsmart_ussd.dbo.ussd_log.[msisdn]) AS totentries,
(
   SELECT COUNT(ussd_clean.dbo.ster_vouchers.sent) FROM ussd_clean.dbo.ster_vouchers 
   WHERE [sent] = '1' AND [sent_date] BETWEEN @start AND @end
) AS [totsent]
   FROM [Cellsmart_ussd].[dbo].[ussd_log]
   WHERE [request] = '*120*789#'

But i also want the query below to be part of the two subqueries above^:

SELECT COUNT([ussd_clean].[dbo].[unique_codes].[msisdn_pair]) AS tota FROM [ussd_clean].[dbo].[unique_codes]
WHERE [msisdn_pair] != '' AND [used] = '1'

Unfortunatly I can't use INNER JOINS because all these single queries refer to
different databases and tables.

Please help me D'Oh! | :doh:

Thanks, Morgs

You can join all the three queries as following.

SELECT COUNT(Cellsmart_ussd.dbo.ussd_log.[msisdn]) AS totentries,

(
   SELECT COUNT(ussd_clean.dbo.ster_vouchers.sent) FROM ussd_clean.dbo.ster_vouchers 
   WHERE [sent] = '1' AND [sent_date] BETWEEN @start AND @end
) AS [totsent],

(
SELECT COUNT([ussd_clean].[dbo].[unique_codes].[msisdn_pair]) FROM [ussd_clean].[dbo].[unique_codes]
WHERE [msisdn_pair] != '' AND [used] = '1'
) AS tota

   FROM [Cellsmart_ussd].[dbo].[ussd_log]
   WHERE [request] = '*120*789#'

It is in the same manner as you joined the first two query.

Also, please post database related question in General Database[^] section.

I can't add much to the previous 2 posts but: what are you hoping to achieve essentially? It may be that you need this, it might be that you don't but please post the scenario that you're working with so that we can advise.

One of the most useful debugging features of .NET Framework is Trace type (or class in C++). Functionally Trace is very similar to Debug type (and they share most of internal implementation), but unlike its Debug sibling that is supposed to be used only during debugging sessions, Trace functions can be compiled into a program and shipped to customers, so in case your users encounter a problem, they can activate trace by simply editing application configuration file.

Trace is easy to use and fully documented in .NET Framework documentation, so I will only briefly go through the basic trace features.

Refer to :
Writing custom .NET trace listeners[^]

I have found the Problem was not on Infragistics. I think someone who does the same as i do will have this problem. To Resolve the Problem i went to the IIS Manager -->Collapse the the tree and select the Application Pools-->In the Managed Pipeline Mode, it was Integrated, i changed it to Classic and it worked.

Thanks

There is no doubt, you can use either appSettings or connectionStrings. ConnectionStrings has built in support in the ConfigurationManager class where as using the appSettings you have to do yourself. Also, connectionSettings is where other components will look by default for connection information.

Use import/export wizard of SQL server(http://msdn.microsoft.com/en-us/library/ms140052.aspx[^]). There's a feature there where you can map the fields from your excel spreadsheet to the fields of your table.

Is RowEditing Event not required in ASP.Net 2.0?

3-Jun-10 23:46

I have a gridview in my form which I am populating data using SqlDataSource. The gridveiw has insert, update and delete. But somehow I forgot to write the RowEditingEvent.

Upon my surpise, when I clicked on Edit button in the grid while executing, the row automatically become editable. Obviously, I have declared the columns with EditItemTemplate.

Is the RowEditing Event not required when I use ObjectDataSource or SqlDataSource? I couldn't find such event in the msdn example also MSDN Link

Thanks

Nope its not. There's no such thing as required event in .Net. Events are raised even if there are no handlers to handle them.
