What kind of question is this? Of course I meant what I said. What is your question even in regard to?

Hello,

I would like to learn C#. I am an intermediate level C++ programmer. Currently I am looking at these books that I heard good things about:

Programming C#, Third Edition by Jesse Liberty
(I am planning on purchasing this book to learn C#. Is there a better one?)

Programming Windows with C# (Core Reference) by Charles Petzold
Windows Forms Programming with C# by Erik Brown

I want to buy one of the above two books (either Petzold or Brown) to learn C# with .NET. Has anyone read either of these books and can make a recommendation?

Any other good books that anyone can suggest?

Thanx for the help.

Gosh... You really are doing the rounds. It looks like your going to have a lot of reading to do! Big Grin | :-D

I've not read the book by Jesse Liberty so I cannot comment to much on it.

The book by Petzold is really a reference book and only really spends the first chapter on C#, the remainder of this very thick (1290 page) book is the .NET Framework in regard to Windows Forms programming. I highly recommend this book for your library if you are going to do Windows Forms applications.

I good introduction to C# is "Microsoft Visual C#.NET Step by Step" as it goes through all aspects of the language and gives a little introduction to many parts of the framework (including ADO.NET, Windows Forms and Web Applications). This book is especially good because there are a lot of keywords that exist in C++ and C# but mean different things. You don't really get that in the other books mentioned.

I've just gotten "Inside C#, second Edition", by Tom Archer, and it's every bit as good as they said it is.

I happen to have all three of these books (What can I say? I'm a bookaholic).

Programming Windows with C# by Petzold is quite good, but most of it is not specific to C# (though all the examples are in C#). He alternates chapters between Windows Forms controls and GDI+. If that's what you're after, you won't be disappointed.

I was given the other two by my dad, who also uses C#.

Programming C# by Liberty (I have the 2nd edition) was very helpful to me. He starts right from the beginning and manages to cover a good number of interesting topics. He assumes the reader has some knowledge of programming and makes direct comparisons between C# and C++.

Windows Forms Programming with C# by Brown was not my cup of tea. (Keep in mind that I don't drink tea, but still...) There seemed to be quite a bit of hand holding, but that's not to say it's a bad book or doesn't contain useful information; It's just not a style of writing I care for.

Why is BOOL in C, cast to int in C#?

21-Dec-03 11:58

QUIT POSTING THIS QUESTION!!!

You have asked it about a dozen times now. I'm the only one that's replied, implying that no one really knows the answer SO YOU HAVE TO FIND IT YOURSELF! I've given you pointers and now you have to complete the research. POSTING THE QUESTION OVER AND OVER WILL NOT GET YOU AN ANSWER!!!

Re: Why is BOOL in C, cast to int in C#?

21-Dec-03 0:27

Is there any particular reason?
I was under the belief that BOOL was cast to bool.

Wouldn't they take up different spaces in memory?

BOOL is not a type, its a typedef.

Only any normal person using C would define BOOL as char, not int.

In Windows headers BOOL is defined as an int, blame MS.

I'm guessing but suspect that a Bool is an int because an int is 32 bits and that is the size that a 32 bit machine can handle with the most efficiency.

It would take more instructions to deal with the Bool if it were a byte.

I work on an embedded project using a Motorola 68K (16bit) and a Bool is defined as an int that is also 16 bits. On 8 bit controllers a Bool, if defined at all, is a char or 8 bits. On a few controllers such as the 8051 types where memory is very limited, they have memory locations that only consist of single bits and can be read or written in a single instruction. In that case a Bool is defined as a bit.

EnumFORMATETC method translation

Tristan Rhodes21-Dec-03 0:14

21-Dec-03 0:14

I have found the EnumFORMATETC method for IDataObject, and they appear to have nothing in common. How does this:

HRESULT EnumFormatEtc(
DWORD dwDirection, //Specifies a value from the enumeration
// DATADIR
IEnumFORMATETC ** ppenumFormatetc
//Address of output variable that receives the
// IEnumFORMATETC interface pointer
);

Get turned into this:

IEnumFORMATETC OleEnumFormatEtc([in] int dwDirection);

i'm very fuzzy on this.

HRESULT EnumFormatEtc(
DWORD dwDirection, //Specifies a value from the enumeration
// DATADIR
IEnumFORMATETC ** ppenumFormatetc
//Address of output variable that receives the
// IEnumFORMATETC interface pointer
);

the way I see it, this should tranclate to:

<br />
int EnumFormatEtc(<br />
int dwDirection,<br />
out IEnumFORMATETC[] ppenumFormatetc<br />
)

the method is expected to return an int that deffines the state of the equasion, not a structure. How can it run? Every other method I have looked at translates:
XXX ** type
into an out array.

Could someone explain this to me?

I'm not entirely sure on this, while I have encountered it before.

I'm just looking for clarification

in: Just put the variable in

out: public void mymethod(out int X);

in/out: use ref?

Formatetc Dummy Entry in decompiler

How to open a word or excel document in my C# windows form

20-Dec-03 23:30

I've been looking at the decompiled versions of various structures, and they are for the most part, very helpful.

While not in the order in which they should be, they still show me what I need to cast things as.

The problem is i've found that in Formatetc, they have added a "dummy" object that is a short (int16), and I do not know the reason for this. I'm assuming it's some kind of buffer for the other objects in the structure, but as they are all ordered in alphabetical order, I don't know where to put it, or what it's there to affect.

Any clues?

Cheers

You can open Word/Excel files that are on the server from the WebBrowser control, but you can't save them again without a workaround, mainly because you would have to use an FTP connection to upload them again.

Write your own code to download them through HTTP or FTP (or whatever you like), open them using the Process class (using ProcessStartInfo for opening the document-related application without knowing), and when that process exits (or you can use the FileSystemWatcher to watch for file changes) upload the document using HTTP or FTP (or whatever). See classes in the System.Net namespace for documentation of helpful classes, but you'll have to code this solution yourself.
