Tearing out my hair on code behind update to MySQL

dbrewerton — Tue, 17 Nov 2009 20:56:12 GMT

Ok everyone, when I do this update clause using code behind it gives me a stupid error that says:

Line: 6
Char: 62099
Error: Sys.WebForms.PageRequestManagerServerErrorExceptio n: Format of the initialization string does not conform to specification starting at index 0.
Code: 0
URL: http://localhost:1038/webapp/admin/assignuser.aspx

Now, my code for the SQL code behind is:

Expand|Select|Wrap|Line Numbers

	                SqlConnection con = null;

                SqlCommand cmd = null;

                try

                {

                    con = new SqlConnection();

                    con.ConnectionString = "SqlDataSource4";

                    cmd = new SqlCommand();

                    cmd.Connection = con;

                    cmd.Parameters.AddWithValue("?aspnet_id", Session["aspnet_id"]);

                    cmd.Parameters.AddWithValue("?contact_id", Session["contact_id"]);

                    cmd.Parameters.AddWithValue("?device_id", Session["device_id"]);

                    con.Open();

                    cmd.CommandText = "update egw_addressbook set aspnet_id = ?aspnet_id where contact_id = ?contact_id;";

                    cmd.ExecuteNonQuery();

                    cmd.CommandText = "update ewise_device set aspnet_id = ?aspnet_id where device_id = ?device_id;";

                    cmd.ExecuteNonQuery();

                }

                catch (Exception)

                {

                    throw;

                }

                finally

                {

                    if (con.State.Equals(ConnectionState.Open)) con.Close();

                }

I am baffled, any idea what's wrong???

How to draw an infinitely scalable image that consists of pixels and text

Kevinst — Tue, 17 Nov 2009 07:55:18 GMT

Hello,

currently I am working on the following scenario:

There is a device connected to my application. That device has a 256x256 pixel display showing graphics and text.

Now for each pixel of that display I receive a flag whether the pixel is to be drawn or not.
Furthermore to display text you can imagine the surface as divided in 21 columns and 16 rows. Now for each cell I get information whether some letter is to be displayed in that cell or not.

By combining these two information I shall be able to draw the device display in any .NET application as if the user was directly watching the device itself.

Now of course it is easy to restrict the application to a client size of 256x256 and just draw every pixel. Once I found a font and font size to fit 21 columns and 16 rows I am good.

But that wont do it as the user wants to be able to scale the display infinitely(however I will force him to keep the aspect ratio).

Now I am evaluating what approach might be the best.
The easiest I can imagine is just draw that 256x256 image and then scale that bitmap using .NETs build in methods. But that might get pretty ugly.. especially for the text artefacts.

I dont know if WPF offers some handy way to manage this?

Thank you!

Kevin

serliazable attribute

captainB — Mon, 16 Nov 2009 06:34:28 GMT

what is the difference between [serializable] and [serializable()]?
Visual Studio intellisense tells me that the [serializable] attribute indicates that a class can be serialized. I understand that.

When I use the other attribute declaration - [serializable()], intellisense tells me
"initializes a new instance of the System.SerializableAttribute class".
Can someone explain to me why I would use this attribute as a constructor?

Thanks!!

Determining 64bit or 32bit architecture

nobodyreally — Mon, 16 Nov 2009 04:57:38 GMT

Hi have been looking forever for how to get the bit version of current RUNNING OS in C#. There are lots of posts out there using the IntPtr.Size and Environment.GetEnvironmentVariable("PROCESSOR_ARCH ITECTURE") but these return what your software is running in (compiled to if other than AnyCPU) regardless of what the OS is running.

I knew I would find it in the win32 but could not figure out where.

Thanks for pointing to the date which allowed me to find the OSArchitecture.

Yep! I'm happy!

Cheers!

Regex syntax

!NoItAll — Sat, 14 Nov 2009 22:02:53 GMT

I'm trying to remove the following from a string
Any occurance of

Here's my string

Hello bright girl

I am trying the .net regex like this

Expand|Select|Wrap|Line Numbers

	sLine = System.Text.RegularExpressions.Regex.Replace(sLine, "<\/?br.*>", String.Empty, RegularExpressions.RegexOptions.IgnoreCase)

and it just doesn't work the way I think it should! I wind up with the following string:
and that's it!
What is wrong with my syntax?

Here's my thinking
< is the literal
\/? escapes the / so I am looking for 0 or 1 / (forward slash)
br is a literal string because I'm looking for "br"
.* I am looking for 0 to many of any character
> the closing literal

I've tried all kinds of combinations - and get close...

The following pattern works pretty well: "<\/?br\W*>"

I get the following string:

Hello bright girl

For some reason, however, it misses the
