MS Word Component Not Getting Created on Windows 2008 64 bit Web Server Edition When I Try Using ASP

Hi All, This might look like a similar question to a lot of you considering there are a lot of web activity happening in terms of blogs/forums/suggestions that I have seen with reference to changes that one needs to do in COM+ Services to enable their ASP.NET Web Application to be able to create Word Objects & I have actually used them personally & they worked for me on Windows 2003 32 bit/64 bit servers. The issue started some 1 month back when I was told that we are upgrading our server to Windows 2008 Web Server edition 64 bit ‘cause of some real benefits it offers if used only as a web server. This was just great as we tested a lot of features /functionality that we were using on our existing server & everything seems to be working just fine on this product by Microsoft. However we also have one web module which is responsible for opening up a MS Word 2007 template file at runtime and fill it with data & is then converted into a PDF document. A lot of ideas on Web suggested that we should move onto Open XML standards to generate documents at runtime, which I have been able to do with no issues. But one activity which still requires me to create a Word document is when I have to convert/SaveAs the Word (docx) document into PDF. I tried all the COM+ & registry related changes that I did on my Windows 2003 64 bit server, but nothing seems

Maximum size of a WriteableBitmap (System.Windows.Media.Imaging.WritableBitmap)

I'm trying to find out the size limits on the WPF WritableBitmap class (ie. System.Windows.Media.Imaging.WritableBitmap, not the Silverlight class with the same name).
In the help for the BitmapSource base class it says:
"The maximum height and width of an image is 2^16 pixels at 32 bits per channel * 4 channels. The maximum size of a BitmapSource is 2^32 bytes (64 gigabytes) and the maximum image size is four gigapixels."
1. By my calculation, 2^32 bytes is 4 Gigabytes, not 64 Gigabytes. So is the size limit 2^32 (4 Gigabytes) or 64 Gigabytes (2^36)? 
2. Are the limits different on 32 and 64 bit versions of the OS?
3. Do these size limits also apply to the derived WriteableBitmap class, or are there further constraints based on available / addressable system memory and/or video (texture) memory?
Thanks in adva

Turn On/Off Windows Component windows is blank in Windows 7 OS


A lot of tips for repairing this relate to Vista.  I have a Windows 7 Professional desktop and cannot turn on/off windows components because it's just blank.  Does anybody have any suggestion on how to populate this window?

Appreciate any response.

Windows Service Applications Tutorials

You can easily create services by creating an application that is installed as a service. For example, suppose you want to monitor performance counter data and react to threshold values. You could write a Windows Service application that listens to the performance counter data, deploy the application, and begin collecting and analyzing data.

Serving Silverlight Apps from Windows Mobile

Even if mobile dev is not my every day work, thanks to the .Net Compact Framework, it's still .Net programming.

Here is the scenario:

You come back home, you have a windows mobile phone wifi capable and you want to quickly get access to your phone pictures from your home network.
You just activate the Wifi, run my app and then browse to the provided link from any computer on the network.

Getting Started with Windows SharePoint Services

Of all of the capabilities of SharePoint, I thought I would start with the most basic installation - as a corporate intranet. It is likely that we will need to discuss some of the elements of SharePoint as we go along, so this also gives us the opportunity to review these elements for future reference.

Before going into too much detail, I would like to point out that you can try the core SharePoint framework (known as Windows SharePoint Services or WSS) for free. On Microsoft's Web site you can download a trial version of Virtual PC 2004 (VPC). Using VPC, you can install the Windows 2003 Evaluation Kit and the WSS add-on. This combination will give you 45 days to evaluate the setup.

Building a Searchable Phone Directory with Windows SharePoint Services

I want to continue to build out the intranet site we've started in our previous articles. A standard item in every intranet is a staff/employee list. Most companies implementing Windows SharePoint Services (WSS) are large enough to have a database that contains all employees. We will use the aggregation features of SharePoint to include data from this database into our intranet.

Getting Started with Windows Communication Foundation

Windows Communication Foundation (WCF) provides a unified framework for rapidly building service-oriented applications that makes it easy to build and consume secure, reliable, and transacted Web services. It unifies the capabilities in ASMX, WSE, Remoting, COM+, and MSMQ; therefore developers need to learn only one programming model.

Application Architecture in Windows Forms 2.0

Applications have special support in Windows Forms. For starters, you can manage and tailor your application's lifetime, and, when the work flow is disrupted by an unhandled exception, you can choose from several methods of response. Then, there are several application models that you can employ, including Single Document Interface (SDI) and Multiple Document Interface (MDI) applications, each of which can support either multiple-instance or single-instance mode, the former the VS05 default and the latter requiring special consideration. All applications, however, can discover and use a wide variety of information about the system and environment they execute in.

Application Architecture in Windows Forms 2.0-Single-MDI Applications

Consider an MDI application like Microsoft Excel; files opened from the file system (by double-clicking) are all opened as separate child windows within the parent Excel window.7 For the first instance of an MDI application to open a new child window to display the file that was passed to the second instance of the application, the second instance must be able to communicate with the initial instance.
