Hi, Sorry but I can't think of any possible causes for your problem. I tried our application now and the API returns success:true, and the numpods is a non-zero number.

It's been a long time since I wrote it but I don't remember having that problem. So I would suggest you compare my code with what you wrote and look for what could be different in the request you make to Wolfram Alpha.

You will find the relevant functions in the files ModuleWolfram.vb and ModuleWeb.vb.

Another idea is to use a Windows PC with Visual Studio 2008 Express and explore the objects and strings in my application and compare them with the similar objects in your application.

The "Math Helper" application does not require installation. You download the ZIP and, after extracting the files, it works immediately.

Here is a screenshot of the application that solved a simple equation and then restored the original "BorderSize" identifier.

The next image shows the version 2.9 with the options in the status bar. The equation in this example is similar to the equations that a programmer needs to solve, when plotting on the screen and then clicking with the mouse on the screen itself.

We used simple examples, but the application has also been tested with very complex equations, and the limit is only the Wolfram Alpha capability to solve them.

The next image shows the most complex equation that we were able to get back during the tests:

For the curious mathematicians, here is the formula that generated the monster:

Solve for x y = a * x ^ 4 + b * x ^ 3 + c * x ^ 2
