6 FAQs (frequently asked questions).

These FAQs are organized by our community groups then by our knowledge base sub-topics.

Expand All

Group: C++

Topic: C++/CLI

-Collapse +Expand Q1. Can you use native code in a C++/CLI application to increase speed?

Yes, that's one of the big advantages of using C++/CLI over C#. Although you can also call unmanaged code from within C#, support for native objects is built into C++/CLI.

I was telling to a friend how impressed I was with the performance of Paint .NET (a free .NET desktop graphics program), and he remarked the the only reason it could peform so well was because it made extensive use of an unmanaged graphics code library.

Group: C# (Visual C# & VS.Net)

Topic: WinForms

-Collapse +Expand Q2. Can I use a Win32 DLL in my Visual Studio.Net application?

Yes. The trick is to use the [DllImport] attribute, followed by declarations for each of the DLL's functions and procedures.

Group: Website Design & Hosting

Topic: Website Hosting

-Collapse +Expand Q3. I've created a web application using v3.5 of the .NET Framework.  But, when I go to deploy it, I find only versions 1.x and 2.x in the ASP .NET dropdown for IIS configuration of my application's virtual directory.  Where is v3.5?  How do I deploy if that's not a configuration choice?

It's not there. You see, v3.5 isn't really a "version" in Microsoft's eyes. 3.5 builds upon v2, and is really considered an incarnation of v2.  Sounds crazy, doesn't it? Not to worry, though, you can still deploy your v3.5 app.  There are just two things that must be done:

  1. The .NET Framework, v3.5 must be installed on the server.
  2. When configuring your application's virtual folder in IIS, choose the v2.x from the ASP .NET version dropdown. 

You'll find this in IIS on the ASP .NET tab of the Properties dialog for your app's virtual directory.

Topic: Removable Storage Technology

-Collapse +Expand Q4. Two relatively new DVD standards have emerged, HD DVD, and Blue Ray DVD. What are the differences?

HD DVDs have a maximum storage capacity of 15 GB for single layer disks, and 30 GB for dual layer disks.

Blue Ray DVDs have a max capacity of 25 GB for singler layer disks, 50 GB for dual layer.

Neither standard is yet a clear "winner."

Topic: psSendMail DLL

-Collapse +Expand Q5. Connect is one of the psSendMail API calls. Unfortunately, Connect is also a reserved word in PowerBuilder. How can I use psSendMail with PowerBuilder?

Connect is, indeed, one of the calls in psSendMail v1. If Connect is also a reserved word in your development platform, this is a problem.

Version 2.0 of psSendMail introduces a new API, and we recommend that all psSendMail users migrate their code to use the new calls in the v2 API. Connect is not used in the new, v2 API.

Note: Connect, and the other v1 calls are retained in v2 for backward compatibility only.

-Collapse +Expand Q6. v2 of psSendMail now allows sending HTML message bodies. Can I include embedded images?

No, not yet.

This is one of the few limitations of psSendMail v2's HTML support, and you can easily get around it by including an image hyperlink - to an image accessible on the web - within your message's HTML body.

Why are embedded images not yet supported?

Many psSendMail v1 users urgently needed two other importart features: authentication, and a little help getting their emails past the "spam police." We focused our efforts on those features first, then added HTML support, and shipped v2 as quickly as possible.

Embedded images are planned for a future iteration of psSendMail.
