VS 2008 Cannot Close Stream Until All Bytes Are Written?
Dec 14, 2010
I am sending a POST request to an API server and I have reused code where I have successfully done this before on other servers and for some reason, which I cannot figure out why, it's not working. I get the error:
Cannot close stream until all bytes are written."}
even though I declared the content length correctly and I am not sure what I am missing here...
data = data + "</posts>"
Dim postBytes As [Byte]() = Encoding.UTF8.GetBytes(data)
Thread.Sleep(10000)
I am sending a POST request to an API server and I have reused code where I have successfully done this before on other servers and for some reason, which I cannot figure out why, it's not working. I get the error:

I have a testing platform that allows data to be posted to a real time collection system. It uses the StreamWriter object to send both HTTP and XML formats, It works fine, but there is a new request to submit uploaded files. This again works fine, unless the files are over 70k (we need to test upto 3MB). If it is over 70k, the response is the content-length too big. I have changed it so that the content-length is now set dynamically, dependant on the size of the file uploaded. However, when the StreamWriter.Close() runs, the execption The request was aborted: The request was canceled. is generated, with the InnerException Cannot close stream until all bytes are written.
From what I have found on the web, the solution is use StreamWriter.Flush(), but this code is already in place.
Does it read the entire message string sent by the client? I have a line to write to the stream later in the code and that does not seem to be sending anything back to the client, although the code around is excuting.
i = stream.Read(bytes, 0, bytes.Length) While (i <> 0) Try ' Translate data bytes to a ASCII string.
I keep getting a ProtocolViolationException "Bytes to be written to the stream exceed the Content-Length bytes size specified." on the following code.I've tried setting Content-Length numerous ways with no success.
Dim url = "https://domain.com" Dim req As WebRequest = WebRequest.Create(url) req.Method = "POST" req.ContentType = "application/xml"
I'm writing a VB.net application (but you can answer in C# if you want, no problem) that uses a 3rd party .NET library. In particular, one method in this library takes an IO.Stream as input (among other things) and writes the results of its processing to said stream. My problem is that the method CLOSES the stream after writing to it, so I can't read back the data that it wrote in it!To be more specific: it works, of course, if the stream is a FIeStream , since it writes the data on disk, but what if I want to read the data directly to memory? I tried using a MemoryStream, but as I said, when the method returns the stream is already closed, and I can't read back anything from it.

I have textbox with vbscript, user could type integers, then hit return key, KeyUp event for return would trigge theWriteFile()being called for com port to write string to the device, if Ihit return key slow, I would get 0bytewritten for WriteFile(), timeout happening basically,if I hit return keyquick,
I would like to use the USB port power as source and use the an amplifier on D+/D- Twisted Pair signal wires as my command line. I saw a thread suggesting to use the output as PWM. How can I send a single byte or stream of bytes to the port. Is it possible to read status of the D+/D- if they are shorted together?
When looking at an array of bytes from a stream for a multi-page tiff document, can you determine where one page stops and another begins? I want to take a multi page document, let's say 50 pages and allow a user to pick different pages of that to make other muti-page documents.
I have this code that was working in a proof of concept app I had - but now will not work.
For Each ddfile As String In ddfiles Dim MyThread As Thread ' simple new thread Dim newFS As FSObject = New FSObject() 'new FSObject which is a file object I made up' used because i needed to keep the name and index matched so the callback function had something to work with
I'm trying to upload a large file (over 50Mb) to my webserver but my app hangs when trying to close the stream. If the file uploaded is larger than 50Mb then the .Close() causes it to hang - no error message at all - however a file less than 50Mb succeeds.
What do you suggest to get around the fstream.Close() hanging my app? Dim target As New Uri(uploadedFilePath) Dim fRequest As System.Net.FtpWebRequest = System.Net.WebRequest.Create(target)
I want it to do is that you input a string, then you select an algorithm (Theres only going to be one RijnDael) then you input a key, then the Initialization Vector comes from "txtIV.text" then you select the key bytes and the block bytes from the numeric up/down, then you either encrypt or decrypt.
Ok i am having some issues designing a base-class to handle generics.Caveat is i need to restrict the type put in as a Numeric type, specifically Int16, Int32, or Int64 (Short or Long).I know you can do Of T as {Structure} but i dont want to select the key bytes and the block bytes from the numeric up/down.
I have set up a notify icon for my form. I want to make it so that when the user clicks the close button that it doesn't close the form it just takes it to shows the notify icon. They can exit the program from the notify icon. Can someone tell me how to keep it running?
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

How can I write the resulted stream to be sure I can read it again later?
Im making a desktop player for a online web radio, and for the program I wanna make it show all the stream info. Like the stream name, and such. However I dont know how to do this? I looked everywhere
The server url is setup like this "[URL]" And it has all the stream info and that there. So is there a way I can get the info from there onto like say a label? Live updates btw.
How would i put * in a password box when text is written in it but only when text is written in it and i want the *'s to be as many as how many characters are entered so if the pass was test it would be 4 *'s
Probably missing something silly here, Her eis what my display looks like Sending image...(401303) I would prefer it displays as Sending image...(391 kb)
I'm currently in the process of building a text editor type program, and have run into a brick wall. I haven't done VB in years, so I may just need a little reminder on some things. I have coded everything so far as far as opening files, saving them, changing fonts, colors, etc. However, I'm looking to add a Close button to my menu strip that will just close the currently opened file, and not the entire program, while also ask the user if he/she would like to save before closing the file, and then if they select yes, it will show the save dialog, and if not, it will go ahead and close the currently opened item.
I am using OLEDB and using datareader and with the read function i am reading table to the form. But now i want the textbox values to be written to the table? I tried with the fill, but not getting.
I have a browse button that only searchs to .map files. This is my code: >>
Private Sub But_Browse_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles But_Browse.Click Dim SelecteerScherm As New OpenFileDialog() SelecteerScherm.Filter = "Only .map files (*.map)|*.map|All Files (*.*)|*.*"
[code]....
When I do ok, how can I get this map file in a textbox ?
I have a rom file that I want to display data from The strings I have already retrieved and displayed the problem now is the image. I have read all the bytes for the part of the file that contains all the data I require EN_Title_Icon which is 2112 bytes. The image data is offset 32 byes in EN_Title_Icon and is 512 bytes, How do I loop the bytes and put them as pixels in the picturebox or a bitmap? And can i use the pallet data that is the 32 bytes after the image data? Here is some info on the image
I have been developing windows and web application using Visual Basic 2005 for a long time. Now i want to change from Visual Basic 2005 to Visual Basic 2008. I would like to know what ever projects i have done in visual basic 2005 will works in Visual Basic 2008. Will the existing code in visual basic 2005 supports Visual Basic 2008 or do i need lot of modification. I haven't used VB 2008 but i hear that most of the code which written in visual basic 2005 supports visual basic 2008. What are the things i need to take care when working the existing projects in visual basic 2008.
