1) What is the difference between windows services & web services
standard protocols, such as HTTP, XML, and SOAP, to access the functionality. XML Web services use XML-based messaging to send and receive data, which enables heterogeneous applications to interoperate with each other. You can use XML Web services to integrate applications that are written in different programming languages and deployed on different platforms. In addition, you can deploy XML Web services within an ?intranet as well as on the Internet. While the Internet brings users closer to organizations, XML Web services allow organizations to integrate their applications.
Windows services run as background processes. These applications do not have a user interface, which makes them ideal for tasks that do not require any user interaction. You can install a Windows service on any server or computer that is running Windows 2000, Windows XP, or Windows NT. You can also specify a Windows service to run in the security context of a specific user account that is different from the logged on user account or the default computer account. For example, you can create a Windows service to monitor performance counter data and react to threshold values in a database.

3) Difference between release mode compilation & debug mode compilation.
:-> Debug and Release are different configurations for building your project.
Release Mode : it basically used for release final version and in this case symbolic file does not make like PDB file and it code execution is optimized, it make application fast, in this mode you can't be dedug your application.
Debug mode : you can easy debug and, symbolic file makes like PDB file is generated in the bin folder.
I also am in the position of looking for employment. I believe, what potential employers are looking for is people that can espouse what they know, are willing to search out what they don't know and learn it, but more importantly, they are looking for people who fit well within their organization. If you don't confidently know the answer to the question, indicate that but, also indicate that you will be checking to make certain.
I've a little strange problem with ReportViewer.
It works at my PC,but when I install my application on the client PC it only shows "Report is being generated" and that's all.No tables,no charts, no data!?!?!
If someone can tell me what could be the problem?-any required .dll may be,or...?
I had the same problems and I deployed the dlls to the machine where the application is to be deployed and it did not fix the problem at all. It seemed at first but created Exceptions. I tried to deploy all the dlls and it was to no use.
I spent days pulling my hair over this and I finally found the solution to it and I want to share that with you. The problem I had was with Visual Studio 2005 Professional. It seems to me that it needs updating.
Go to http://support.businessobjects.com/downloads/merge_modules.asp#07 and download the Crystal Reports for .NET Framework 2.0 Redistributable Package (x86) (other versions are available for 64 bit machines), which contains the CrystalReportRedist2005_x86.msm file when unzipped. Unzip it and you will also get a word document which explains what to do in a very well illustrated way
Sorry for posting here.
I could not find details from winzip/winrar sites. And I am deleloping a web pages that has capability to compress files. And I am using .NET for this. And I hoped if someone may did this. That's why I posted here and I got the result.
My code is as below :
if (lbl == "Valid")
var lbl1="<%= str1 %>";
alert("Bio-metrics have not been done");
Can anybody please tell me how to do it. Thank you.
I am currently using VS 2005 (.NET 2.0) and want to install the .NET 3.0 framework and start working on it.
I have installed the .NET 3.0
Now i am told that i will need to install the Windows SDK and .NET 3.0 components and then
install the VS 2005 extensions for the .NET 3.0
When reading through the Windows SDK install link in MS site, it is suggesting to do several things, including un-installing the current Windows SDK and also says there are several known issues around this install.
It is also asking to uninstall existing stuff like Document explorer etc. which i use with VS 2005 (for documentation).
And the list of things to do looks pretty long
The current machine is my production machine where i develop 2.0 based apps / controls and i want to be careful when installing the 3.0, especially the Windows SDK.
Can anybody share their experience on this bit - i.e. the Windows SDK instalaation bit.
Oncei get over this step, i can happily install the 3rd bit - i.e. the VS extensions for .NET 3.0 and have fun with .NET 3.0 fluff
If your just going to play with .NET 3.0 don't install it on your production machine. Install something like VirtualPC, install Windows on a new virtual machine, then Visual Studio .NET 2005 and all the .NET stuff. That way, you can play all you want safely without screwing up your production environment.

Why??? Is .NET 3.0 not RTM'ed yet? It is RTM!!!!!! I would be worried only if it was a RCs or Betas, but with RTM release, MS should ensure that it does not screw up any production environment, especially the .NET 2.0 system. If they cannot assure that, they should not be releasing .NET 3.0 as RTM at all. They should keep it as Beta if the developer community will have to be cautious to use it in production machines running 2.0 framework (or use it via Vistual PC etc.).
I have typed datasets in the designer. I have table adapters that i have dragged from the server explorer. I have used these for the last couple of month. I have added queries, stored procedures, added and deleted fields in the table adapters.
Now, I added an extra column to one of my tables in sql server 2005. I right clicked the relevant table adapter and clicked configure, and included the extra column.
I build the program, but the changes to the table adapter does not reflect in the code. When I do the following: tableAdapter.insert() the extra column has not been included.
I tried this with another table adapter in the dataset designer by adding a new field. The same problem.
I used rebuild, i have deleted the table adapter and added a new one. I have restarted VS, and also restarted the computer. I have also opened the project on another machine. I have deleted the table adapter from the form designer and added a new one from the components tab. And still the same problem.
When I preview the data, the extra column is there. But not when I use it in code.
Can anyone please tell if they know about this problem and is there a way to solve it.
You required to reconfigure the Typed dataset, I had faced same problem what I did was I had regenerated the designer class from the tool. The problem here is you will have the old designer which not getting regenerated.
So either try to regenerate it or recreate the complete typeddataset which will have tableadaptor etc
