WCF Service upload file

[d2005]

Hi Guys,

Im at a total loss with this one.
every time i attempt it i think im worse off for the experience.

Basically I have a service which is working fine in regards to getting data in and out of my database
(consumed by windows form application)

now i need a routine where the user(from the windows application) can upload files(images) to my server - where the service and website is hosted.

Am i going about this the wrong way or is this the way to go for uploading files ?
Any vb.net links or tutorials welcome.

Thanks

D

this is the right way to go. You dont want external users having direct access to the database. By keeping it in a service, you can do some upfront validation in the client, file sizes, no malitious uploads etc.

Thanks bill,

Do you know of any links or keywords i can look for as i need to see some examples ?
anything ive tried to this point has failed (its been a while now since i tried this and im only coming back to it now)

IM in a world of hurt with this...
Any help at all is greatly appreciated


Ive tried many different things ive seen on the web with this being the simplest i can see. Im thinking hes not giving me all of the information i need.
other issues i had with other solutions were parser errors saying behaviour dont exist...

anyway - as it stands at the moment ive reverted to this 'simpler' solution
The appconfig of my client

            <basicHttpBinding>
                <binding name="BasicHttpBinding_IService1" closeTimeout="00:01:00"
                    openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
                    allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
                    maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
                    messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
                    useDefaultWebProxy="true">
                    <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647"
                        maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
                    <security mode="None">
                        <transport clientCredentialType="None" proxyCredentialType="None"
                            realm="" />
                        <message clientCredentialType="UserName" algorithmSuite="Default" />
                    </security>
                </binding>
            </basicHttpBinding>

and the web config of my wcf is like so

 <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="myBindingForBigArrays"
        maxReceivedMessageSize="2147483647">
          <readerQuotas
          maxDepth="64"
           maxStringContentLength="2147483647"
          maxArrayLength="2147483647"
          maxBytesPerRead="4096"
           maxNameTableCharCount="16384"/>
        </binding>
      </basicHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>

but my issue still remians
its like the image / file im sending is too big
