Datagrid delete button in asp net

Tue, 01 Sep 2009 21:49:00 -0700

Posted a 'new message on the ASP.NET forum.

after adding a delete button to a datagrid in a asp net website, i want to know how to enable deleting a record of database table using this button. this is the error message after clicking that button:

Deleting is not supported by data source 'SqlDataSource1' unless DeleteCommand is specified.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.NotSupportedException: Deleting is not supported by data source 'SqlDataSource1' unless DeleteCommand is specified.

--------------

how can i specify delete command? is this a good way to delete a database record? what do you usually do? i prefer old style tables and links. like what i do in php.

i need a simple compiler code written using vb. do you have it? or an online link to such program?

this compiler should support fundamental instructions such as - if-then, for , ... up to 10 action.

opening a dialogue box is better, as it is the standard procedure.
but what about the printing action? method or module or the common way that programmers usually use.

What are different ways of printing in C#. what method do you usually use to print a document with desired structure.

I use methods like:

//event handler
PrintDocument pd = new PrintDocument();
pd.PrintPage += new PrintPageEventHandler(pd_PrintPage);
pd.Print();

//draw image
System.Drawing.Image p = System.Drawing.Image.FromFile(image);
Point q = new Point(40, 75);
e.Graphics.DrawImage(p, q);

//draw string
e.Graphics.DrawString(name, new Font("Tahoma", 11), Brushes.Black, new PointF(750, 95), drawFormat);

--------------------

is there any easy style module for printing? I prefer to use HTML tags to make my documents and then a module that prints this HTML source on the paper.

what are your personal ways?

I'm writing a simple editor using EMU8086. it gets keys as input and shows corresponding letters and numbers on the screen.

how can i distinguish Home and End keys? or how to move the cursor to the begin or end of the line I'm writing after pressing those keys?
thank you.

Re: Text in graphical mode?

Posted the message 'Re: Text in graphical mode?' on the x86 Assembly forum.

thanks. i think it can be easy if we cosider letters as an array of pixels, and then send those pixels to the screen. i did it for advertising boards using LEDs and C programming. for example a C letter can be defined in a 8*8 matix. then there are 8 bytes to define letter C. now we can send them to the screen. somthing like this!?

int 10 works, but letters would be BOLD an awful in this case. is it correct? or i'm wrong!

Text in graphical mode?

Posted the message 'Text in graphical mode?' on the x86 Assembly forum.

what is the idea to write a desired text in different sizes,colors or languages in graphical mode in 8086 asmbly?

for example letter 'C', we want to make a bitmap table for it and then to show it in small size on the screen. i saw somwhere 'C' could be defined like this:

; C
DW 07000H,08800H,08000H,08000H,08000H,08800H,07000H

but how do this values can make letter 'c'.
and if so, what is the next step to show just this single letter on the screen.
thanks for any code.

not too much complicated. a simple instance like DEBUG program in windows shell.

cmd

which shows memory information from 0:0 - 0:100
