Hi,
to get the best results when the overlay contains either lines with fixed thickness (such as cross-hairs) or text, both of which don't scale well, this is what I would try:
1. either don't use an overlay bitmap at all, just draw the overlay in real-time
2. or generate a new overlay bitmap every time the video display gets resized
Both have in common that they should work at the display resolution, not the original video resolution.

Hiii
I am developing one window application in c# and .net with sql server 2005 as database.
now, i have Four questions:
1] I have one dropdownlist in form and i want to fetch the content/data of table category in to this dropdownlist and when I run this form on clicking dropdownlist the data should be displayed in dropdownlist.
2] As i said one dropdownlist is there and also one textbox is there in this form , now i am selecting one value from dropdownlist and entering keyword or text in textbox and pressing button search, on click event of this button it should compare the dropdownlist and textbox and depending upon the comparision the result should be display in datagridview. the value of dropdownlist and textbox are the data member of table Product
and result should be fetch in datagridview from this table "Product"
3] In Web application we have file uploader control so how we can provide file upload facility in window application?
4] How We can make search of particular keyword in PDF files?
I am really frustating by this questions and my project arrived at the deadline please help me!
I hope You will Help me in good way! Thanx in Advance.

1 and 2 are pretty trivial. It's obvious that 3 and 4 and totally beyond you. I recommend that in future you learn the language/platform you're paid to code in, instead of asking people to do your work for you after the deadline expires.
For number 1 and 2, I can only say, learn to use google and buy a book. They are both trivial.
For 3 - a web app is already connected to the server. Your app is not. The easiest way to do this, is to create a web service on the server that takes the information of a file, and then use that to send files to your server.
For 4 - you need to buy a PDF library.

Be patient. Deadlines come and go. Nothing to worry about.

How about telling us the exception message, and what's different ( such as different office versions ) between the two machines ?

It is the same version of office, it's office 2007 plus, thank you verry mutch.

OK. But what error message you are getting ?
I think (just a guess) that you dont have correct filepath. i.e. you are using D:\xyz and D: is not there or xyz is not there.
or try this.
in Office 2007
*) Open the 2007 Microsoft Office system application in question. Click the Microsoft Office button, and then click Application Options.
*) Click the Trust Center tab, and then click Trust Center Settings.
*) Click the Macro Settings tab, click to select the Trust access to the VBA project object model check box, and then click OK.
*) Click OK.
Or try opening excel application (manually) and then run your code.

Try this one.
1. Click Start, click Run, and then type DCOMCNFG. Select the application that we want to automate. The application names are listed below:
2. Microsoft Excel 97/2000/2002/2003 - Microsoft Excel Application
3. Click Properties to open the property dialog box for this application.
4. Click the Security tab. Verify that Use Default Access Permissions and Use Default Launch Permissions are selected.
5. Click the Identity tab. Verify that The Launching User is selected.
6. Click OK to close the property dialog box and return to the main applications list dialog box.
7. In the DCOM Configuration dialog box, click the Default Security tab.
8. Click Edit Defaults for access permissions. Verify that the following users are listed in the access permissions, or add the users if they are not listed:
SYSTEM
INTERACTIVE
Everyone
Administrators
OfficeAutomationUser
IUSR_<machinename>*
IWAM_<machinename>*
* These accounts exist only if Internet Information Server (IIS) is installed on the computer.
9.Make sure that each user is allowed access and click OK.
Click Edit Defaults for launch permissions. Verify that the following users are listed in the launch permissions, or add the users if they are not listed:

I don't believe that the .NET email classes have ways to set a proxy server.

Hi,
I want to access the data of a PDF file which is opened on IE using BHO.
Using a Browser Helper Object, how can I come to know that a PDF file is opened on IE.
The BHO in the following link is helpful for retrieving data of web pages.
http://www.codeproject.com/KB/cs/Attach_BHO_with_C_.aspx?fid=447248&df=90&mpp=25&noise=3&sort=Position&view=Quick&fr=51&select=2421069
But how the PDF file data can be retrieved?

I will be using a IE toolbar button to mark it...
But how can change it so that i can read the encrypted html?
Thank you

We didn't need to see all this code. So, you're saying you can decrypt it, but you want to display it in IE via a toolbar ? So, you want to intercept an HTTP request and decode it, right ?
Does it have to be in a toolbar, could it be in an app that contains an IE control and then does the HTTP request ?

No,
Cause this encrypt is hardcode
How can i do like this: Use getElementsByName()
if my
var x=document.getElementsByName("encrypt");
How can i capture those encrypt in the html and ancrypt it?
