Hi Gurus,
I have an Application, in which
1) need to post data to a URL(Remote Server), by using HTTPRequest.
2) get the Image data in the form of Stream in Response.
3) need to save this stream as a Image file on the local machine.
Giving some code snippet below.
RequestAPI = CType(WebReques t.Create(URLNam e), HttpWebRequest)
RequestData = ImageName
RequestAPI.Cont entType = "applicatio n/x-www-form-urlencoded"
RequestAPI.Meth od = "POST"
StoreRequestStr eam = New StreamWriter(Re questAPI.GetReq uestStream())
StoreRequestStr eam.Write(Reque stData)
'Close the StreamWriter Object
StoreRequestStr eam.Close()
StoreResponse = CType(RequestAP I.GetResponse() , HttpWebResponse )
Dim ImgStream As Stream
Dim StremaLen As Long
ImgStream = StoreResponse.G etResponseStrea m()
StremaLen = StoreResponse.C ontentLength
'**** For Saving Image File ****
WriteImgFile(Im gStream, StremaLen)
Public Sub WriteImgFile(By Val ImgStream As Stream, ByVal RespLen As
Long)
Dim BinReader As BinaryReader
BinReader = New BinaryReader(Im gStream)
Dim BinWriter As BinaryWriter
Dim objDestFile As FileStream
Dim ImgByteArr() As Byte
ImgByteArr = BinReader.ReadB ytes(CInt(RespL en))
Try
objDestFile = New FileStream("D:/ImageTest/Test.jpg",
FileMode.Create , FileAccess.Writ e)
BinWriter = New BinaryWriter(ob jDestFile)
BinWriter.Write (ImgByteArr)
Catch ex As IOException
End Try
End Sub
The problem is, I get StoreResponse.C ontentLength as -1, which prevents
me from saving the Stream data as File. Actually Image resides on the
server. How this can be achieved ?
Any help in this regard would be appreciated.
Thanking you in anticipation.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
