RTF to HTML converter in C++

Download source code (9KB)

Nearly, I used RichEditCtrl in a MFC project, and I want to take formatted RTF text in that control to display on a HTML control. I searched through CodeGuru and found this one. It’s a nice job, but it leaks 2 things:

• Doesn’t work well with unicode. In fact, it can’t recognize unicode characters.
• A minor error when calculating font size.

As you maybe known, in RTF format, an unicode character is encoded in two ways:

• \u6884: 6884 is character code (in decimal) of this letter (it’s “Ấ“) .

• \’1EA4: 1EA4 is character code (in hexadecimal) of this letter (it’s “Ấ“) .

So I slightly modified Daniel Beutler’s code in order to work around these problems. You can found my code in the following functions: CRTF_HTMLConverter::R2H_CreateHTMLElements and Util::StringToLong.

Serialize and deserialize BITMAP object in MFC/Win32

Download the source code

Lately, in one of my project, I have to save an BITMAP object into an XML document. The problem is I can only save an CString into the XML document. So I have to find a way to convert BITMAP data (in a HBITMAP) into CString.

It’s pretty easy if I serialize the BITMAP to an byte[] array, and then convert the result byte[] array into CString format. So I will consequently discuss on these 2 problems.

Sending SMS message in Windows CE

Download the source code

Today I will show the way to send SMS message in Windows CE and Windows Mobile, using C++ and P/Invoke in .NET CF. It’s pretty simple…

In Windows CE environment, SMS fuction is handled by “sms.dll”, but in Windows Mobile 2005 and later, it’s handled (in a much more simpler way) by “cemapi.dll”. The “cemapi.dll” is not documented very well, in the other hand, you can find lots of information about “sms.dll” on MSDN.
