I have an array of Bytes. Most of these are interpreted as Unsigned. On certain occasions I need to interprete the byte as signed. Why can't Byte convert to SByte? What I'm doing: I'm trying to program a disassembler for an 8-bit video game ROM. My program reads the ROM and processes each instruction. The instructions are interpreted as unsigned. Some arguments for instructions would be treated by two's complement in the original hardware, however, to make a signed number.

View 2 RepliesI'm using Response.AppendHeader("Refresh", "2; url=default.aspx") To send users back to the home page after they log in or log out and it works.

The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.Requested URL: /default.aspx, 2; url=default.aspx The weird thing is this doesn't happen in debug, only on the live site.

Using VB 2008 .NET 3.5..I am working on an N-Layer desktop application.Suppose a method in the BLL runs into an situation where the user needs to be notified and the method needs to wait for the user input (OK, Cancel, etc.) before continuing.Assume that this situation happens fairly often but not all the time, and is expected. It doesn't seem correct to throw an exception. The only solution I have so far is to raise an event with a custom EventArgs, and allow the UI to set some property in the custom EventArgs to reflect the user input.

I am trying to build an application that will return a responce from a url containing an CGI "get" or "set" instruction. Example : Http:192.168.1.56:...in/get?exposure This is the syntax that would be entered into any web browser to solicit the IP camera for the current exposure value.
What I am trying to do is build an application that will allow these responces to be placed into a TextBox. Conversly I want to place values into a text box and submit the new value. Example: Http:192.168.1.56:...set?exposure=10

When I am posting data, there is no actual post data. The data I enter into the web page is only in the hex view or the raw data. How can I send a request using raw data or whatever method with a webrequest?
If you run this code, builder.Append("Content length: " & response.ContentLength & _" bytes" & vbCrLf)
it returns a string builder object which shows the number of bytes contained in the page. But the url here must exceed some sort of character limit because it is returning -1 as the value which means (Unknown?)
