  • Which C# Book to take?

    - by Fischkopf
    I was searching for a book to learn C#, but now i'm kinda stuck. I found many people asking the same question, and many people gave answers, but there are so many books about C# that it is really hard to decide which one to take. Now i reduced my choice on two books, but I just can't decide between them. Namely, there are: Programming C# 4.0 and C# 4.0 In A Nutshell The first thing I want to know, are these good choices? I'm not completely new to programming, but I just didn't find the right language until know, but i think C# is the one I was searching for. I know all the bassic stuff from Delphi/Java/Python so I think i'm not a complete beginner in programming. Is there anyone out there that read both books and can cleary explain whats the difference between them? I haven't found many reviews and sort of, so I just don't know which one to chose. Or is there any book that is better suiting me?

  • Use iconv API in C

    - by Constantin
    I try to convert a sjis string to utf-8 using the iconv API. I compiled it already succesfully, but the output isn't what I expected. My code: void convertUtf8ToSjis(char* utf8, char* sjis){ iconv_t icd; int index = 0; char *p_src, *p_dst; size_t n_src, n_dst; icd = iconv_open("Shift_JIS", "UTF-8"); int c; p_src = utf8; p_dst = sjis; n_src = strlen(utf8); n_dst = 32; // my sjis string size iconv(icd, &p_src, &n_src, &p_dst, &n_dst); iconv_close(icd); } I got only random numbers. Any ideas? Edit: My input is char utf8[] = "\xe4\xba\x9c"; //? And output should be: 0x88 0x9F But is in fact: 0x30 0x00 0x00 0x31 0x00 ...

  • How to workaround Python "WindowsError messages are not properly encoded" problem?

    - by Victor Lin
    It's a trouble when Python raised a WindowsError, the encoding of message of the exception is always os-native-encoded. For example: import os os.remove('does_not_exist.file') Well, here we get an exception: Traceback (most recent call last): File "<stdin>", line 1, in <module> WindowsError: [Error 2] ???????????: 'does_not_exist.file' As the language of my Windows7 is Traditional Chinese, the default error message I get is in big5 encoding (as know as CP950). >>> try: ... os.remove('abc.file') ... except WindowsError, value: ... print value.args ... (2, '\xa8t\xb2\xce\xa7\xe4\xa4\xa3\xa8\xec\xab\xfc\xa9w\xaa\xba\xc0\xc9\xae\xd7\xa1C') >>> As you see here, error message is not Unicode, then I will get another encoding exception when I try to print it out. Here is the issue, it can be found in Python issue list: http://bugs.python.org/issue1754 The question is, how to workaround this? How to get the native encoding of WindowsError? The version of Python I use is 2.6. Thanks.

  • Native Windows Application Development Options

    - by Michael Stum
    Long winded title, short question: If one wants to develop for Windows but not have to rely on any external dependency (no runtime, thus ruling out .net), what supported, alive and fully functioning* alternatives are there? Visual Basic 6 is dead, Visual C++ is obvious and Delphi seems to be the prime choice for that, but I wonder if there are any other alternatives? *as in: Being able to use all the Windows Features like putting an icon in the Notification Area, making the Taskbar Icon flash etc.

  • Free visual editor for a language that would compile to native windows exe

    - by luvieere
    I'm looking for a free visual editor for a language that would compile to native windows exe, no runtime. I'm looking for alternatives to the Delphi suite (so don't give it as an answer), something that would allow me to write Windows GUI applications with ease. I don't care about the language, as long as it gets the job done, but I would appreciate if your suggestions avoid functional languages. Even better if it abstracts the windowing system with something more simple than the winAPI.

  • Writing SDK documentation, need useful beginner tutorials

    - by David Rutten
    I'm currently writing SDK documentation for one of our products, but for obvious reasons I don't want to talk about the essentials of OOP. Does anyone know any good online teaching material that explain (aimed at absolute beginners) concepts such as classes, inheritance, constructors, instances etc.? Preferably urls that are likely to survive for a couple of years to come... It's a DotNET SDK and we're including only VB and C# samples, so C++ or Delphi or Lisp material is not that useful.

  • USB windows xp final USB access issues

    - by Lex Dean
    I basically understand you C++ people, Please do not get distracted because I'm writing in Delphi. I have a stable USB Listing method that accesses all my USB devices I get the devicepath, and this structure: TSPDevInfoData = packed record Size: DWORD; ClassGuid: TGUID; DevInst: DWORD; // DEVINST handle Reserved: DWord; end; I get my ProductID and VenderID successfully from my DevicePath Lists all USB devices connected to the computer at the time That enables me to access the registry data to each device in a stable way. What I'm lacking is a little direction Is friendly name able to be written inside the connected USB Micro chips by the firmware programmer? (I'm thinking of this to identify the device even further, or is this to help identify Bulk data transfer devices like memory sticks and camera's) Can I use SPDRP_REMOVAL_POLICY_OVERRIDE to some how reset these polices What else can I do with the registry details. Identifying when some one unplugs a device The program is using (in windows XP standard) I used a documented windows event that did not respond. Can I read a registry value to identify if its still connected? using CreateFileA (DevicePath) to send and receive data I have read when some one unplugs in the middle of a data transfer its difficult clearing resources. what can IoCreateDevice do for me and how does one use it for that task This two way point of connection status and system lock up situations is very concerning. Has some one read anything about this subject recently? My objectives are to 1. list connected USB devices identify a in development Micro Controller from everything else send and receive data in a stable and fast way to the limits of the controller No lock up's transferring data Note I'm not using any service packs I understand everything USB is in ANSI when windows xp is not and .Net is all about ANSI (what a waste of memory) I plan to continue this project into a .net at a later date as an addition. MSDN gives me Structures and Functions and what should link to what ok but say little to what they get used for. What is available in my language Delphi is way over priced that it needs a major price drop.

  • How to find out if an object is of <type> or a decendant of <type>

    - by Vaccano
    I have the following code: foreach (var control in this.Controls) { } I want to do something like control.Hide() in there. But the items in the this.Controls collection are not of type Control (they are Object). I can't seem to remember the safe way to cast this to call hide if it is really of type Control and do nothing otherwise. (I am a transplanted delphi programmer and I keep thinking something like control is Control.)

  • Are there any programmable barcode scanners that can call a webservice?

    - by Mark Redman
    I am looking at integrating a C# application with a barcode scanner. The last time I did this was with Delphi 1 (win 3.11) using a scanner that plugged in-line into the keyboard cable. Looking around it appears most scanners are USB based these days and assume they emulate keyboard entry. Anybody know of more sophisticated/programmable scanner that can call a webservice or even just do a basic POST/GET this would eliminate the C# application and the computer to support it?
