How to format and update GridView and DataGrid rows using JQuery

The behavior described in this question is as expected. When you set text of a cell in grid, it directly affects HTML that is going to be rendered.

The column that GridView creates for command fields (Edit, Delete and Select) are a (anchor) or button elements. So you can see what will happen if you set text value in that cell. It will wipe out those link or button controls and replace them with simple text string.

Format Generic List Bound to Gridview


I have a generic list of a custom type. The custom type has a string and double.

I'm binding the list to a gridview and it outputs everything fine.

I'm trying to format the double column into a currency format. It is in a template field as I'm calculating a running total. I pass the value to a function that returns a double and adds the current value to a running total which I will show in the footer.

The format is not changing to currency as expected when using String.Format("{0:c}", GetTotal(Convert.ToDouble(Eval("Amount"))))

Any ideas on what might be going on and how to fix this?

Inside Windows: An In-Depth Look into the Win32 Portable Executable File Format, Part 2


The Win32 Portable Executable File Format (PE) was designed to be a standard executable format for use on all versions of the operating systems on all supported processors. Since its introduction, the PE format has undergone incremental changes, and the introduction of 64-bit Windows has required a few more. Part 1 of this series presented an overview and covered RVAs, the data directory, and the headers. This month in Part 2 the various sections of the executable are explored. The discussion includes the exports section, export forwarding, binding, and delayloading. The debug directory, thread local storage, and the resources sections are also covered.

Inside Windows: An In-Depth Look into the Win32 Portable Executable File Format


A good understanding of the Portable Executable (PE) file format leads to a good understanding of the operating system. If you know what's in your DLLs and EXEs, you'll be a more knowledgeable programmer. This article, the first of a two-part series, looks at the changes to the PE format that have occurred over the last few years, along with an overview of the format itself. After this update, the author discusses how the PE format fits into applications written for .NET, PE file sections, RVAs, the DataDirectory, and the importing of functions. An appendix includes lists of the relevant image header structures and their descriptions.

COM: Handle Late-bound Events within Visual Basic Using an ATL Bridge


Since a Visual Basic client doesn't handle events directly from late-bound COM objects, it needs some way to capture all the events and parameters launched by any COM object server instantiated at runtime and not known at design time. This article explains how to build a bridge component that does just that. The bridge component transmits the intercepted event data back to the Visual Basic client using another supporting COM object that is capable of holding event data and attributes. The Visual Basic client receives the notification from the bridge and extracts all the information relative to the event from the supporting object.
