My system has Japanese regional settings. I have used this as default encoding in my code. But Encoding.GetString() method doesn't return proper length because of DBCS.[code]

i got a problem when receiving data from networkstream that was converted from bytes to string.. the output would be the same but when i compare the the string generated from Encoding.ASCII.GetString() compared to the actual string, the output is not the same..
This is my code..

just for ping purposes.. :)
my server pings to client..is there any instance that when the string will be converted to bytes, the string will change?
I am not sending any sensitive or security information in the query string. I am currently using Base64Encoding along with MD5 Hash. I want to shorten my url as far as possible.

Given a byte array of length 100..I would like to find a function that returns a byte array starting at index 15 and containing the next 20 bytes.
View 4 RepliesI am new to the Window's API and have been trying to just poke around with it. It was suggested to me to try making a time tracker program that will track how long a window is actively being used and keep windows from the same .exe file grouped together. Things have been going good so far, but I am having trouble with the GetModuleFileNameEx command.
According to MSDN if GetModuleFileNameEx succeeds it should return the length of the path name; however, when I output the return value of GetModuleFileNameEx, it is just a random long number that changes with every tick of the timer. Also when i try to output the path of the open window just to see what is being stored there, it is blank. I have googled and surfed the net for but to no avail. I was curious if someone here might have an answer for me Here is the code I am having trouble with:

I have a function in my WinForms app that needs to retrieve the user's default user agent. To do this, I've created a web page (ASP.NET) that displays the user agent in a Label in the Page_Load. The problem that I'm having is that when I fetch the HTML from that page, the result includes all of the HTML except what should be displayed in the LabelHere's my
Private Function GetUserAgent(ByVal theUrl As String) As String
Dim proc As New Process
proc.StartInfo.CreateNoWindow = True[code].......
However, when viewing the page's source in a browser, it contains the following .Your user agent is: <span id="Label1">(user agent string here)</span></p>.why GetString is not picking up the Label contents?
Note: For reasons beyond my control, this app is coded using .NET 1.1. Otherwise, I'd be doing things a bit differently.
Am I just being blind or does this If statement genuinely not do what it's meant to.[code]This displays the message box even though textSample is one of the letters. In my eyes that If statement should see that textSample is one of those letters and skip it, whereas if it was Z it would "Not" be equal to any of those and would therefore show the message box.

i am using vb2010 and mysql community server.
I'm using Visual Studio 2005, and I have a datagrid connected to a table from an Access database.
I added 4 textboxes so the user can type search filters to search within the table and a "search" button.
Then, I created a query using the "add query" tool on the datagrid. I wrote it like: select field1, field2, field3, field4, field5, field6 from table where field1=? and field2 like "%"+?+"%" and field3 like "%"+?+"%"
and field4 like "%"+?+"%"
Both field5 and field6 aren't search criterias, so I didn't add them to the query. Once the query was created, I replaced the parameters inside the procedure with my textbox1.text, textbox2.text, textbox3.text, textbox4.text and then cut and pasted the whole thing inside my SEARCH button click event, so the query is executed when the user clicks on the button.
Now the problem is: when I search using the first field it goes ok, but when I try to search by any of the other fields it returns zero results, even though I double-checked I had written the words correctly. I don't know why it does this. I already tried deleting the datagrid and creating it again.[code]...

View 5 RepliesI have a function to recursively search through windows (and their child windows) to find specific ones, it works exactly as expected, however it causes "function doesn't return a value on all paths" warning.

in an winForm app in VS2010 win 7 compiling to x86, I try to do what Alvas.Audio seems to work. See (c# ex: [URL] for reference.
Dim data() As Byte = wr.ReadData(second * i, second)
The result give me data.length()=0. I do not have any exception, I can read format from it and whatever reader I use I got this problem.EDIT : After some tests, it seems like the uncompressed file I create in the first step (in PCM format, with .wav extension) can not be recognized by the Alvas.audio library for the second step. I must miss something around Audio file markups or something alike.
Here is the code that might be the source (basically this is step 1):
Dim functOut As String = String.Empty
Dim wr As Alvas.Audio.IAudioReader = Nothing
Dim fs As IO.FileStream = Nothing

I have a field displaying on a datagrid that the user has asked to be variable length based on the data that is returned. Is there an easy way to determine how many characters are returned for a field and then converting that to a pixel length so that I can change the length of the field in the code.

If using the following in an if statement I get an error: If trg.Name.Substring(4, 6).ToUpper <> ("ABCDEF") Then I get the error: "Index and length must refer to a location within the string. Parameter name: length"
I assume this is because the string (trg.name) is too small for the 4, 6 substring. What would be the correct method of working around this problem? VB.net Studio 2008.
