Vala Image Base64 in Web - linux

I would like to know if in Vala (Soup.Server) I can visualize an image
that I have as a string in base64 format?
private static void default_handler (Soup.Server server,Soup.Message msg,string path,GLib.HashTable? query,Soup.ClientContext client) {
var imgStr = (string) Base64.decode ("iVBORw0....");
msg.set_response("image/jpeg",Soup.MemoryUse.COPY,"%s".printf(imgStr).data);
}1

solution
void handle_static_file(Soup.Server server, Soup.Message message,
string path, HashTable? query, Soup.ClientContext context) {
server.pause_message(message);
handle_static_file_async.begin(server, message, path, query, context);
}
async void handle_static_file_async(Soup.Server server,
Soup.Message message, string path, HashTable? query,
Soup.ClientContext context) {
if (path == "/" || path == "") {
path = "index.html";
}
var file = File.new_for_path("static/" + path);
try {
var info = yield file.query_info_async("*", FileQueryInfoFlags.NONE);
var io = yield file.read_async();
Bytes data;
while ((data = yield io.read_bytes_async((size_t)info.get_size())).length > 0) {
message.response_body.append(Soup.MemoryUse.COPY,
data.get_data());
}
string content_type = info.get_content_type();
message.set_status(Soup.Status.OK);
message.response_headers.set_content_type(content_type, null);
} catch (IOError.NOT_FOUND e) {
message.set_status(404);
message.set_response("text/plain", Soup.MemoryUse.COPY,
("File " + file.get_path() + " does not exist.").data);
} catch (Error e) {
if (debug) {

Get posted file over HTTP Listener in c#

I have make a simple http server using c#. And I know how to get posted data and output them. Here is my c# code
public static void start(){
HttpListener listener = new HttpListener();
listener.Prefixes.Add(new Uri("http://localhost:8080").ToString());
istener.Start();
while(true){
HttpListenerContext con = listener.GetContext();
showPostedData(con.Request);
con.Response.StatusCode = (int)HttpStatusCode.NotFound;
string data = "Uploaded successful";
byte[] output = Encoding.ASCII.GetBytes(data);
con.Response.ContentType = "text/html";
con.Response.ContentLength64 = output.Length;
con.Response.OutputStream.Write(output , 0, output.Length );
}
}
public static void showPostedData(HttpListenerRequest request){
if (!request.HasEntityBody)
{
return;
}
System.IO.Stream body = request.InputStream;
System.Text.Encoding encoding = request.ContentEncoding;
System.IO.StreamReader reader = new System.IO.StreamReader(body, encoding);
string text;
if (request.ContentType != null)
{
text = reader.ReadToEnd();
}
Console.WriteLine( text );
}
My client html form has input box named file: <input type="file" name"file">
In the console output is like that :
file='Path of Choosed file not a file'
So How i get POSTED files and copy them to upload directory..?
Sorry for my english and thanks in advance...

DbSet<T> is not thread-safe, so you can't use it from multiple threads at the same time. It seems you're trying to fix that by using a lock, but you're doing that incorrectly. For this to work, all threads have to share a single lock object. Having separate lock object for each thread, like you do now, won't do anything.
Please note that I received the same exception with the application I was working on, and determined that the best way to resolve the issue was to add an AsyncLock, because of what #svick mentioned about how DbSet is not threadsafe. Thank you, #svick!
I'm guessing that your DbContext is inside your businessLayerObj, so here is what I recommend, using Stephen Cleary's excellent Nito.AsyncEx (see https://www.nuget.org/packages/Nito.AsyncEx/):
using Nito.AsyncEx;
// ...
private readonly AsyncLock _dbContextMutex = new AsyncLock();
public void CheckForServerHealth()
{
using (await _dbContextMutex.LockAsync().ConfigureAwait(false))
{
await MyDbContextOperations(businessLayerObj).ConfigureAwait(false);
}
}
private async Task MyDbContextOperations(BusinessLayerClass businessLayerObj)
{
await Task.Run(() =>
{
// operations with businessLayerObj/dbcontext here...
});

and in return i am obtain response as net.rim.device.cldc.io.dns.DNS Exception:DNS Error
Please help me in this regard
Thanks And Regards

Please have the answer for my own question helps in parsing wcf rest services developed in .net and parsed at blackberry end.
This 2 classess definitely helps in achieving the above code parsing.

SD Card's Free Size

I want to check the free size available on My Device's SD Card. I know FileConnection API. How can I check the free size of the SD Card ?
The idea is to open the cfcard file connection and call availableSize() on it. to get the proper memory card location read it from the System.getProperty(...). In some devices the aforesaid property may fail hence constructing new path from the memory card name system property.
NOTE: In certain devices the hostname must be 'localhost', hence change the return string in getFilehost() appropriately.
PS: Since this is a code snippet certain form / command references may throw null pointer please resolve it accordingly.
Below code with get you the available size in 'BYTES' of the memory card
String memoryCardPath = System.getProperty("fileconn.dir.memorycard");
addToLogs(memoryCardPath);
if (null == memoryCardPath) {
displayAlert(null);
}
nativeHostname(memoryCardPath);
addToLogs(nativeHostname);
String path = buildPath(memoryCardPath.substring(getFilehost().length()));
addToLogs(path);
long availableSize = getAvailableSize(path);
addToLogs(String.valueOf(availableSize)+" Bytes");
if(availableSize == 0L) {
String memoryCardName = System.getProperty("fileconn.dir.memorycard.name");
addToLogs(memoryCardName);
path = buildPath(memoryCardName + "/");
addToLogs(path);
availableSize = getAvailableSize(path);
addToLogs(String.valueOf(availableSize)+" Bytes");
if(availableSize == 0L) {
displayAlert(null);
return;
}
}
displayAlert(String.valueOf(availableSize));
Supporting methods
public String buildPath(String foldername) {
if(null == foldername) {

}
addToLogs("[BP]"+getFilehost());

}
String nativeHostname = null;
public void nativeHostname(String url) {
String host = url.substring("file://".length());

nativeHostname = host.substring(0, index);
} else {

}

public String getFilehost() {
