With MySQL this worked, however, including the JAR file from HSQLDB (here: hsqldb-1.8.0.10.jar) did not make a new tab show up (as is the case with MySQL). Is there a way to 'convince' SQLdeveloper working with HSQLDB and JDBC? FYI, I am using Squirrel too but it's not as comfortable to work with compared to SQLdeveloper.

Hi, I need to retrieve an image by doing an HTTP 'Get' request and convert it to Base64 so that it can transported in an XML string. I also need to convert it back from Base64 to Image format so that it can displayed in a webpage/winform. I am performing the following steps for the first task: • Retrieve image binary stream from a web location by doing HTTP 'Get' Request • Convert the data in stream to string by doing Stream.ReadToEnd() • Convert the string to byte-array by doing Encoding.GetBytes() • Convert byte-array to Base64 by doing Convert.ToBase64() Following are the steps for the second task: • Convert Base64 to byte-array by doing Convert.FromBase64() • Convert byte-array to binary stream by passing byte-array to MemoryStream() constructor • Create Image object by doing Image.FromStream(). I wanted to convert a Stream to an Image and the method: - Image img1 = Image.FromStream(datastream) //datastream is a Stream here, an object of the class stream works very well in a desktop application. Dreamfall the longest journey pc italiano. However, if I want to use this method in a mobile application for windows mobile 6, I found ti does not work. This is because the System.Drawing class does not at all contain the definition of a method such as FromStream() With further investigation I found out that the System.Drawing.dll was being imported from the.NET framework to the IDE in case of the desktop application, whereas in case of mobile application, the System.Drawind.dll was being imported from the SDK of the.NET Compact Framework.

Push the 'Convert to Base64 Image' button on the top of the page. Put the raw Base64 string into the textarea, select the type of the image (JPEG,PNG,GIF) and push the 'Decode' button. If the Base64 string is a valid image it will be displayed in full size. The Convert Base64 to Image was created for quickly convert base64 string to Image or Decode image from Base64 encoded string. How it Works? Just paste your Base64 string to the textarea above and click to the button 'Convert' and you will get your Image.

Now, the issue is that the Visual Studio IDE uses two different dll's for desktop appplication and mobile application. Nonetheless, the System.Drawing.dll for desktop application DOES have the method FromStream but the System.Drawing.dll for mobile application DOES NOT have the method FromStream() Hoping for an invaluable reply Thanks in advance Ankur.
