Hi,

I have 4 different cameras located in my home.
These 4 cameras are connected to 4 channel DVR.
DVR store recorded video stream data in raw format on one attached hard disk drive.
I assign static IP address to this DVR, and DVR throws video streams on this IP address and 80 port.

Are there any ways to read video streams from this IP address and 80 port of DVR.

Regards,
Kunal.

A label has a font property. You can use that to set the font for the Label text.

If you use Reflector, you can easily dig out the internals of how PrivateFontCollection works, and wrap up your own implementation using just the bits you need. (Here's a hint - I just took a quick peek using Reflector and found that adding a new font relies on:

[DllImport("gdiplus.dll", CharSet=CharSet.Unicode, SetLastError=true, ExactSpelling=true)]
internal static extern int GdipPrivateAddMemoryFont(HandleRef fontCollection, HandleRef memory, int length);

Not sure. See if this[^] helps. Looks somewhat similar to what you are doing.

Deleting a Registry Key Gives a Security Exception

Richard Andrew x6412-Jul-09 17:37

My program creates a registry key under HKEY_CURRENT_USER\Software.

There is no problem creating the key or creating values underneath it.

However the framework throws an UnauthorizedAccessException when I try to delete the key using the "DeleteSubKey" method of the RegistryKey class.

The program is running as the same user that created the key.

This is on Vista SP2.

What could I be missing? I thought that a user has total access to keys underneath HKEY_CURRENT_USER?

Never mind!

I found out that I'm supposed to open the key with delete-access to begin with.

Thanks for reading my post.

A) Why? Why not just use the RadioButtons?

B) If the RadioButtons are in the same group, you only need to check one, the framework will uncheck the other(s) for you.

Otherwise, I'd use the TextChanged event of the TextBox and maybe a switch.

Issues with adding a web reference using WSDL.exe

Hello guys,

I needed to create a proxy by adding a web reference into my C# class library project, but there's been some issues configuring the thrid party product and the webservice they expose....so I have manually downloaded the WSDL file (its not asmx, its actually java/ibm web service).

Anyways, since i can't use the add web reference wizard from Visual studio anymore, I'd like to know how to I create a porxy (Reference.cs) file in my project using the WSDL file located on my C drive.

Can anyone point me to the right direction, I treid looking into Wsdl.exe but looks like it only support a URL and not a local path, if it does can someone point me to the right command syntax?

I'd appreciate your help.

Thanks
Tina
