• Python, SWIG and other strange things

  - by wanderameise

  hey, I have a firmware for an USB module I can already control by visual C. Now I want to port this to python. for this I need the octopus library which is written in c. I found a file called octopus_wrap which was created by SWIG! then I found a makefile which says: python2.5: swig -python -outdir ./ ../octopus.i gcc -fPIC -c ../../liboctopus/src/octopus.c gcc -fPIC -c ../octopus_wrap.c -I /usr/include/python2.5 gcc -fPIC -shared octopus_wrap.o octopus.o /usr/lib/libusb.so -o _octopus.so python2.4: swig -python -outdir ./ ../octopus.i gcc -fPIC -c ../../liboctopus/src/octopus.c gcc -fPIC -c ../octopus_wrap.c -I /usr/include/python2.4 gcc -fPIC -shared octopus_wrap.o octopus.o /usr/lib/libusb.so -o _octopus.so win: gcc -fPIC -c ../../liboctopus/src/octopus.c -I /c/Programme/libusb-win32-device-bin-0.1.10.1/include gcc -fPIC -c octopus_wrap.c -I /c/Python25/libs -lpython25 -I/c/Python25/include -I /c/Programme/libusb-win32-device-bin-0.1.10.1/include gcc -fPIC -shared *.o -o _octopus.pyd -L/c/Python25/libs -lpython25 -lusb -L/c/Programme/libusb-win32-device-bin-0.1.10.1/lib/gcc clean: rm -f octopus* _octopus* install_python2.4: cp _octopus.so /usr/local/lib/python2.4/site-packages/ cp octopus.py /usr/local/lib/python2.4/site-packages/ install_python2.5: cp _octopus.so /usr/local/lib/python2.5/site-packages/ cp octopus.py /usr/local/lib/python2.5/site-packages/ I dont know how to handle this but as far as I can see octopus.py and _octopus.so are the resulting output files which are relevant to python right? luckily someone already did that and so I put those 2 files to my "python26/lib" folder (hope it doesnt matter if it´s python 2.5 or 2.6?!) So when working with the USB device the octopus.py is the library to work with! Importing this file makes several problems: >>> Traceback (most recent call last): File "C:\Users\ameise\My Dropbox\µC\AVR\OCTOPUS\octopususb-0.5\demos\python \blink_status.py", line 8, in <module> from octopus import * File "C:\Python26\lib\octopus.py", line 7, in <module> import _octopus ImportError: DLL load failed: module not found. and here´s the related line 7 : import _octopus So there´s a problem considering the .so file! What could be my next step? I know that´s a lot of confusing stuff but I hope anyone of you could bring some light in my mind! thy in advance

• Accurately display upload progress in Silverilght upload

  - by Matt

  I'm trying to debug a file upload / download issue I'm having. I've got a Silverlight file uploader, and to transmit the files I make use of the HttpWebRequest class. So I create a connection to my file upload handler on the server and begin transmitting. While a file uploads I keep track of total bytes written to the RequestStream so I can figure out a percentage. Now working at home I've got a rather slow connection, and I think Silverlight, or the browser, is lying to me. It seems that my upload progress logic is inaccurate. When I do multiple file uploads (24 images of 3-6mb big in my testing), the logic reports the files finish uploading but I believe that it only reflects the progress of written bytes to the RequestStream, not the actual amount of bytes uploaded. What is the most accurate way to measure upload progress. Here's the logic I'm using. public void Upload() { if( _TargetFile != null ) { Status = FileUploadStatus.Uploading; Abort = false; long diff = _TargetFile.Length - BytesUploaded; UriBuilder ub = new UriBuilder( App.siteUrl + "upload.ashx" ); bool complete = diff <= ChunkSize; ub.Query = string.Format( "{3}name={0}&StartByte={1}&Complete={2}", fileName, BytesUploaded, complete, string.IsNullOrEmpty( ub.Query ) ? "" : ub.Query.Remove( 0, 1 ) + "&" ); HttpWebRequest webrequest = ( HttpWebRequest ) WebRequest.Create( ub.Uri ); webrequest.Method = "POST"; webrequest.BeginGetRequestStream( WriteCallback, webrequest ); } } private void WriteCallback( IAsyncResult asynchronousResult ) { HttpWebRequest webrequest = ( HttpWebRequest ) asynchronousResult.AsyncState; // End the operation. Stream requestStream = webrequest.EndGetRequestStream( asynchronousResult ); byte[] buffer = new Byte[ 4096 ]; int bytesRead = 0; int tempTotal = 0; Stream fileStream = _TargetFile.OpenRead(); fileStream.Position = BytesUploaded; while( ( bytesRead = fileStream.Read( buffer, 0, buffer.Length ) ) != 0 && tempTotal + bytesRead < ChunkSize && !Abort ) { requestStream.Write( buffer, 0, bytesRead ); requestStream.Flush(); BytesUploaded += bytesRead; tempTotal += bytesRead; int percent = ( int ) ( ( BytesUploaded / ( double ) _TargetFile.Length ) * 100 ); UploadPercent = percent; if( UploadProgressChanged != null ) { UploadProgressChangedEventArgs args = new UploadProgressChangedEventArgs( percent, bytesRead, BytesUploaded, _TargetFile.Length, _TargetFile.Name ); SmartDispatcher.BeginInvoke( () => UploadProgressChanged( this, args ) ); } } //} // only close the stream if it came from the file, don't close resizestream so we don't have to resize it over again. fileStream.Close(); requestStream.Close(); webrequest.BeginGetResponse( ReadCallback, webrequest ); }

• .NET Deployment Framework

  - by Khash

  Many people use Nant or Powershell for deployment of their apps to different servers/environments. These are based on scripting while some solutions allow deployment to be embedded in code like Migrator.Net and other Ruby inspired Db deployment/migration frameworks in .NET. I was wondering if there are any frameworks for .NET for application deployment that would allow developers to embed full deployment inside code. Things like copying files, creating web apps in IIS, stopping and starting services and so on.
