MORE INFORMATION

Page 4: Creating An Empty Project Only Valid For Visual Studio.Net

On page 4, there is a description on how to create an empty project. The option of creating an empty project is available with Visual Studio .NET, but not with Visual C# .NET Standard Edition.

We have made available a file that allows you to add an empty project in Visual C# .Net.

Download and save the file emptypro.exe onto your hard disk, then double-click the file to extract the file CSharpExForEmptyProject.vsdir into the \Program Files\Microsoft Visual Studio .NET\VC#\CSharpProjects folder.

The following file is available for download from the Microsoft Download Center:

emptypro.exe

CD-ROM: New ImageIO.cs And MetafileConvert.cs Files

On the companion CD, files ImageIO.cs (\Code\Dialog Boxes\ImageIO) and MetafileConvert.cs (\Code\Metafiles\MetafileConvert) contain errors in their code. The files with the corrected code are available now for download.

Page 12: Typographical Error

There is a typographical error on page 12 in the second-to-the-last paragraph. Change:
"Date types don't need..."

To:
"Data types don't need..."

Page 14: Correction To AddFive Routine

On page 14, in the AddFive routine,

Change:
"i + 5;"

To:
"i += 5;"

Page 45: Int16 Should Be Int32

There are two incorrect references to Int16 in the middle of page 45.

Change:
"is an alias for the Int16 structure."

To:
"is an alias for the Int32 structure."


Also change:
"System.Int16 a = 55;"

To:
"System.Int32 a = 55;"

Page 56: Missing ")" In Code Sample

There is an error in the "switch and case" construction coding example at the bottom of page 56. The end of line four is missing a closing parenthesis.

Change: 

switch (MessageBox.Show("Do you want to create a new file?",
                                     "WonderWord",
                                     MessageBoxButtons.YesNoCancel,
                                     MessageBoxIcon.Question)

{
case DialogResult.Yes:
        // "Yes" processing
        break;


To: 

switch (MessageBox.Show("Do you want to create a new file?",
                                     "WonderWord",
                                     MessageBoxButtons.YesNoCancel,
                                     MessageBoxIcon.Question))

{
case DialogResult.Yes:
        // "Yes" processing
        break;



Pages 116 & 118: SystemColor Should Be SystemColors

There is an error in the code samples on page 116 and 118. The four instances total of "SystemColor" on pages 116 and 118 should be changed to "SystemColors".

Page 203: Incorrect Chapter Cross-Reference In First Paragraph Of Page

In the first paragraph on page 203, in the fourth line,

Change:
"find out about in Chapter 11...."

To:
"find out about in Chapter 13...."

Page 244: Incorrect Capitalization In Code Sample

The beginning of the Caret class towards the bottom of Page 244 contains five instances of the following program instruction:

[DLLImport("user32.dll")]

When the reader attempts to compile the Caret.cs file, the following error message is thrown:

...\Caret.cs(13): The type or namespace name 'DLLImport' could not be found (are you missing a using directive or an assembly reference?)

The reason the compiler generated this error is because the two letter "L's" in the word "DLLImport" are capitalized. (Please note an example of the proper way to write this statement can be found on the sixth line of Page 239.)

Error Solution:
Change the two upper case letter "L's" to lower case letter "l's."

Correction:
The beginning of the Caret class towards the bottom of Page 244 should contain five instances of the following program instruction: [DllImport("user32.dll")]


Pages 252 and 253: Incorrect Hebrew Character Leading To Misspelling Of "Boker"

In the second paragraph of the "Right-to-Left Problems" section on page 252, in the second line, replace the sentence that is there with the following:

"We're going to type the Hebrew for 'good morning,' which is ???? ???, commonly transliterated as boker tov."

In the second sentence of the second paragraph under the table on page 253, replace the sentence "So to type...(the c key)." with the following:

"So, to type the Hebrew phrase shown above into TypeAway, you need to type the letters in this order: bet (the c key), vav (the u key) qof (the e key), resh (the r key), space, tet (the y key), vav (the u key), and bet (the c key)."

Page 289: Incorrect Square Roots Within Graphic At Top Of Page

On page 289, in the graphic (G07PL09) on the top of page 289, all instances (8) showing the square root of 2 should instead show the square root of 1/2.

Page 298: OnPage Should Be DoPage

There are two typographical errors at the bottom of page 298.

Change:
"The OnPage method changes..."

To:
"The DoPage method changes..."


Change:
"OnPage then switches..."

To:
"DoPage then switches..."

Page 382: Remove Extra Space From Code

The seventh line from the end of the AllAboutFont.cs program located on Page 382 states:

"GdiVerticalFont : " + Font.GdiVerticalFont + "\n" +

Remove the space between the Font property and the colon character in the aforementioned line and in the program's output display window at the bottom of Page 382.

This line should read:

"GdiVerticalFont: " + Font.GdiVerticalFont + "\n" +


Page 403: Two Incorrect Values In TestRenderingHint Enumeration Table

On page 403, In the TextRenderingHint Enumeration table, the fourth and fifth lines should be switched and the values in the second column changed. Change the fourth row from:

"AntiAlias 3 Anti-aliasing, no grid fitting"

To:
"AntiAliasGridFit 3 Anti-aliasing with grid fitting"

And Change the fifth row from:

"AntiAliasGridFit 4 Anti-aliasing with grid fitting"

To:
"AntiAlias 4 Anti-aliasing, no grid fitting"

Page 416: How the DrawString Should Be How does the Drawstring

There is a typographical error in the middle of page 416.

Change:
"How the DrawString call interprets ampersands?"

To:
"How does the DrawString call interpret ampersands?"

Page 472: Error In Code Sample

On page 472, there is an error in the JeuDeTaquin.cs code sample.

Change:
"BorderStyle = FormBorderStyle.Fixed3D;"

To:
"FormBorderStyle = FormBorderStyle.Fixed3D;"

Page 484: Out-of-date Info In Paragraph

On page 484, in the section titled "Bitmap File Formats",

Change:

"Exif The Exchangeable image format was developed by the organization now known as Japan Electronic Industry Development Association (JEIDA) for use in digital cameras. The specification is published on the Web site of the International Imaging Industry Association (I3A), formerly the Photographic and Imaging Association, Inc. (PIMA) at http://www.pima.net/standards/it10/PIMA15740/Exif_2-1.PDF."

To:

"Exif The Exchangeable image format was developed by the organization now known as Japan Electronics and Information Technology Industries Association (JEITA) for use in digital cameras. The specification for EXIF 2.2 can be found here: http://www.exif.org/Exif2-2.PDF. "

Page 489: Incorrect URL

The ImageFromWeb.cs program defines an incorrect string variable named 'strUrl' located approximately in the middle of Page 489.

Change:
"string strUrl =
"http://images.jsc.nasa.gov/images/pao/AS11/10075267.jpg";"

To:
"string strUrl =
"http://images.jsc.nasa.gov/lores/AS11-40-5903.jpg";"

Page 515: Correction To Save Method

On page 515, in first paragraph under "More on the Image Class", remove:

"The first version of Save in the following list uses the filename extension to determine the file Format, but you can be more explicit in the next two versions:
...
void Save(string strFilename)"

Page 770: Single Class Should Be Single Structure

There is an incorrect statement in the middle of the third paragraph on page 770.

Change:
"The point size has to be converted from a string back to a float using the static Parse method of the Single class."

To:
"The point size has to be converted from a string back to a float using the static Parse method of the Single structure."
