    Re: Converting std::string to System::String

    You've been on the right track with std::string::c_str(), it's just that its result type (SByte * from the .NET perspective) isn't implicitly convertible to System::String. You need to explicitly...
  2. Re: Breaking up large class into manageable source files

    Then your central problem is not the user interface, it's organization and generation of your data. What you currently have seems to be some sort of custom browser for your users to conveniently view...

    Re: Newbie help with chars and ASCII!

    In C++/CLI (AKA managed C++), the standard C++ keyword char is a synonym for the .NET type SByte. This is an 8 bit signed numeric type, so the behavior you describe is not surprising. The standard...
  4. Re: Breaking up large class into manageable source files

    From a design principle point of view, static class members are often questionable, and global (i.e. not a member of any class) entities like your Initialize() function even more so. But ok, it's...
  5. Re: Breaking up large class into manageable source files

    There's basically no problem in separating a large class into more than one .cpp file. The only thing that needs to be kept as a single piece is the class boby with the data member declarations and...

    Re: A question regarding a debug error.

    Just a marginal remark, adding to what the two other contributors already posted correctly: You started this thread in the wrong forum section; your code quite obviously is native C++, not C++/CLI...
  7. Re: Need help on how to use open file dialog with multiple files

    The OpenFile() method you're using only ever returns the first file selected in the dialog. This is by design, and having a look at the method's return type (Stream ^) it couldn't be able to return...

    Re: Help with a really simple program

    Ok, if your decision for C++/CLI as the language of choice has been taken, and if your goal is a program that performs something that has been done earlier by a set of batch files (or if your program...

    Re: Help with a really simple program

    Hmmm, well... Your approach looks pretty paradox, even starting with its fundamental concept: The DOS/Windows batch file language is, by its very concept, inclined towards the primitive/trivial kind...

    Re: Bold, Italic Tag Help!!

    You can do an additional replace pass before the ones that apply the tags, that removes any bold, italic or underline formatting from all paragraph marks:

  12. Re: Problem accessing array created in the same class

    As Victor already pointed out, your problem here is that, though your array actually is created on the managed heap, your tracking handle variable that refers to the array is a local variable to the...
  13. Re: Declaring member variables in a windows form app

    You're right, writing a Windows Forms app without involving .NET is impossible, simply because Windows Forms is part of the .NET Framework Library.

    Howerver, there's a few .NET-less alternative...
  14. Re: Declaring member variables in a windows form app

    If your goal ist platform independence, you'd typically either use a cross-platform framework like Qt or KDE, or you'd write your own abstraction/adapter layers that isolate your platform-unaware...
  15. Re: Declaring member variables in a windows form app

    You actually could use the Win32 LoadImage() in you managed app, but why would you want to? It would dramatically complicate things without gaining you any reward, compared to simply using what the...
  16. Re: Declaring member variables in a windows form app

    No. Of course the variable would need to be of type Image ^ (or of one of the two derived types Bitmap ^ or Metafile ^, if you're sure the image you're loading is of the respective type and want to...
  17. Re: How to structure and step through a project using vb.net and vc++.net

    I'm not exactly sure about actual JIT debugging, but attaching to a running process works with the Express, it's just that the respective menu item remains invisible until advanced features are...
  18. Re: How to structure and step through a project using vb.net and vc++.net

    AFAICT you're right, but to me the issue here seems to be mixed language debugging rather than mixed mode. While, in fact, that isn't supported by the Express versions either, I have a potential...

    Re: Button to display text box message

    So then simply assign the text "1" (in double quotes, as opposed to the numeric value 1 without the quotes) to the text box' Text property.

    However, you'll probably want to also be able to use...
  20. Re: 68hc11, largest unsigned contents of memory question

    Yeah, at such a low level it's pretty difficult to clearly draw the line of dstinction between an understandable explanation and the practical equivalent of a given-out solution. After asking whether...

    These are the general steps your program needs to take in order to accomplish its goal:

    Well, you don't actally explain what your code shoud do which in fact it does not. The term "Calculator" you mention gives a very vague idea of the direction your intentions are heading to, but...
