However, I recently tried to use it in a repeater. Essentially my company wants to have a number of different values displayed as the main repeater (no problem setting that up). When the user clicks on a field within that repeater, they would like the collapsible panel to open up and display the detail information for that piece of data. The details are within a sub repeater.The repeater functionality and the child repeater functionality are working perfectly. So the repeater and the child repeater aren't the issue. If I take the collapsible panel extender out the data displays perfectly.The problem is that once I start opening and closing the panels, the screen rendering starts to go crazy, and there seems to be no rhyme or reason for it.
For example, on the initial screen rendering I get seven entries. They look perfect. Each of the seven line up across the screen and no extraneous data is shown.I click to open the first row, and it displays great. No problem. But when I then click it again to close the first row, I only see the first four rows of data, then a huge white space with a few seemingly random characters, then the next 2 rows, a smaller whitespace, then the seventh row. I click to open the first row again and everything looks exactly as it should again. Again close, again 4 rows, whitespace, 2 rows whitespace, last row.I reload the page and everything is ok.
So now I click on the second row to open it and everything looks perfect. I close the second row and I get the exact same result.Has anyone ever tried to use the ajax collapsible panel inside a repeater? If so, have you encountered strange rendering behavior such as this? And if so, were you able to get it to work?Here's a stripped down version of the

I have a text file that I am reading from which is a list of first and last names. They are in order but they are on different lines of the text file. I am trying to read them into an array and put the first and last names together on separate lines.

I'll try to explain what i'm doing here, i wan't look through a text file, adding certain lines to an individual array element. So i want to build an array with mcode, mTitle, mCredits, mSemester, moduleStats, currentYear <--- this information as an array element. So here is my attempt at the code,
Dim sr As StreamReader = New StreamReader("datasource.txt")
Dim line = sr.ReadLine() ' get each line and store it

I'm using WinPcap to capture incoming data. Basically I'm dealing with a continuous stream of incoming data, either as byte array or as memorystream (pieces up to 64kb).
I need to check this data to see if there's a certain url and then extract it.
The url I need to find looks like this:http://201.122.38.5/data/today/798572987-589571?139805890582 The length of the 'code' after "/today/" is always the same. The IP address changes. What's the best/fastest/most efficient way to continuously check these byte arrays or memorystreams and extract the urls without hogging the CPU too much?

below is a byte array to string encoder. It uses the yEnc algorithm that is used for Usenet binaries (Usenet only supports text).
Doing a performance analysis in VS2010 shows that this is the most CPU intensive part of the application.
The encoder function is used thousands of times, so I'd like to optimize it as much as possible.
I'm using 'ReDim Preserve' instead of 'Take()ToArray', because I'm targeting .NET Framework 2.0. Is there a more efficient way of getting only a part of a byte array?

I'm trying to get a string from a byte array previously read from memory
i can get the string like this
dim mem as string= ASCIIEncoding.ASCII.GetString(memory) or dim mem as string= UTF8Encoding.UTF8.GetString(memory) but when i try to concatenate this with another string i get a strange result dim result as string = "this is you memory string " & mem & " problem string" no matter what comes after mem in the concatenation it seems like it is not there when in fact it is because when i try this (mem has two chars in it) dim result as string = "this is you memory string " & mem(0) & mem(1) & " problem string" problem string appears so what i assume is that there are some vbCrLf chars in the string after reading (or is it from the conversion?)

I am writing an OPC Client in VB.NET (2008) and I am using an OPC wrapper from Graybox. I am having some problems with the data types. I have an Array of String that contains all of the OPC Items that I wish to read from the OPC Server.

View 8 RepliesI've been working with a sig capture application sample on a windows mobile device, The data is sent via IP to a host as a byte array and is then drawn onto the screen of the host as it appeared on the client. I was able to get this into the form of a bitmap object so I could print it or save to a jpg file. That all works well. The problem now is that I need to store this data in a database and then be able to recall it at a later time and recreate the signature image.
The byte array data is much smaller than the actual image so I would like to store it in that form. My issue is that when I convert this byte array into a string and back again my program can no longer re-create the image. Once I saw the problem I created the code below as a test and added the msgboxes to get an idea what was happened to my data.
