Синтаксическая ошибка идентификатор form1

Take out the .h, that’s the filename, you want to instantiate an object of type Form1. Application::Run(gcnew Form1());

Did you rename your Form1 class something else?

The file names are irrelevant. What is you class called?

• Hello,

  >Error: [B]syntax error : identifier ‘MENUITEMINFO'[/B]
  >Code: [CODE]static int GetMenuItemInfo(IntPtr hMenu, int uItem, bool fByPosition, MENUITEMINFO %lpmii);[/CODE]

  Have you defined the “MENUITEMINFO” structure before the code? If you have defined after, you may use a forward declaration before this
  line to compile the code.

  >Error: [B]syntax error : identifier ‘_'[/B]
  >Error: [B]error C2238: unexpected token(s) preceding ‘;'[/B]
  >Code: [CODE][StructLayout(LayoutKind::Sequential, CharSet=CharSet::Auto), StructLayout(LayoutKind::Sequential, CharSet=CharSet::Auto)]_;[/CODE]

  You have the unwanted extra symbol “_” before “;”

  Remove the “public” specifier.

  MENUITEMINFO is a native structure for menu which is defined in winuser.h (include Windows.h).
   In Managed C++, you don’t have to create a wrapper structure and do the P/Invoke as C# or VB, you can direct call the native api’s after include the “Windows.h”.

  >Error: [B]error C2039: ‘arrow_black’ : is not a member of ‘System::Windows::Forms::Control::Properties'[/B]

  >[B]error C2065: ‘arrow_black’ : undeclared identifier[/B]

  >Code: [CODE]PictureBox1->Image = Properties::arrow_black; [/CODE]

  There is no arrow_black defined in ‘System::Windows::Forms::Control::Properties’. If you want to load an image from a file, a GDI handler or stream,
  please use
  System::Drawing::image.   

  >Error: [B]error C2664: ‘void Microsoft::Win32::RegistryKey::SetValue(System::String ^,System::Object ^,Microsoft::Win32::RegistryValueKind)’ : cannot convert parameter 3 from ‘bool’ to ‘Microsoft::Win32::RegistryValueKind'[/B]
  >Code: [CODE]Registry::LocalMachine->CreateSubKey(«SOFTWARE\\MyApp\\TrayEnabled»)->SetValue(«Enabled», «False», this->NotifyIcon1->Visible == true);[/CODE]

  The third parameter of RegistryKey::SetValue is

  RegistryValueKind Enumeration which specifies the data types to use when storing values in the registry, or identifies the data type of a value in the registry. In your code, “this->NotifyIcon1->Visible ==
  true” is a bool value but not a value kind. Please make sure what is register key value kind for the key you are set. For example if the key’s type is a DWord, fill the third parameter as RegistryValueKind::DWord.

  Have you defined a class or namespace called “MY”? Please double check the code.

  Change the
  LocalMachine.OpenSubKey to LocalMachine::OpenSubKey. you are calling a static method of Microsoft::Win32::Registry.

  If you have any concern, please let me know.

  Cheers,

  Have you taken the time to look up that error in the compiler’s
  help — either locally or online? It should make clear what
  you’re doing wrong.

  It’s difficult for anyone to give exact solutions to some
  of your errors as there is no context for the single lines
  of code which you are posting. Often the code lines you
  show would be valid in one context but invalid in another.

  e.g. —

  Valid:

  int main(array<System::String ^> ^args)
  {
    System::Collections::Generic::List<int> ^myindexes =
      gcnew System::Collections::Generic::List<int>();
    return 0;
  }

  Invalid:

  ref class A {
  public:
    // C3845 error
    System::Collections::Generic::List<int> ^myindexes =
      gcnew System::Collections::Generic::List<int>();
  };

  Valid:

  ref class A {
  public:
    static System::Collections::Generic::List<int> ^myindexes =
      gcnew System::Collections::Generic::List<int>();
  };

  Valid:

  ref class A {
  public:
    A();
    System::Collections::Generic::List<int> ^myindexes;
  };

  A::A()
  {
    myindexes = gcnew System::Collections::Generic::List<int>();
  }

• Hi Mark,

  >>System::Collections::Generic::List<int> ^myindexes = gcnew System::Collections::Generic::List<int>();

  >>error C3845: ‘Project1::Options1::myindexes’: only static data members can be initialized inside a ref class or value type

  You cannot initialized a non-static type inside a ref class, please define it as static or initialize it in a constructer. E.g.
  

  ref class myclass

  {

     
  //System::Collections::Generic::List<int> ^myindexes = gcnew System::Collections::Generic::List<int>(); //C3845

     
  //static System::Collections::Generic::List<int> ^myindexes = gcnew System::Collections::Generic::List<int>();

     
  System::Collections::Generic::List<int> ^myindexes;

     
  myclass()

     
  {

      
  myindexes = gcnew System::Collections::Generic::List<int>();

     
  }

  };

  >>error C3094: ‘System::Runtime::InteropServices::StructLayoutAttribute’: anonymous usage not allowed

  An attribute was not scoped correctly. For more information, see
  User-Defined Attributes.

  >>error C2143: syntax error : missing ‘;’ before ‘using’

  Double check if you miss a “;” at the end of some class.

  String^ URL = «http://www.mysite.com/myscript.php?user=» + Form2::ComboBox1::Text & «&pass=» + Form2::TextBox1::Text;

  error C2597: illegal reference to non-static member ‘System::Windows::Forms::Form::Text’
  

  error C2568: ‘+’ : unable to resolve function overload

  To access the some control inside form, you need to use “->” but not “::”. Normally, “::” is for accessing namespace
  or static member.

  >>And how I can add the images in the application and use the properties to extract the images from the application?

  You can use
  System::Drawing::Image class’s static method
  Image::FromFile to create an image from the specified file.
  

  I’m not clear about what you mean “use the properties to extract the images from the application?”, could you explain it a little
  bit more?

  Cheers,

  Yi

• Hello,

  Hello,

  >Should I have to change from this:

  >System::Collections::Generic::List<int> ^myindexes = gcnew System::Collections::Generic::List<int>();

  It depends on your code. From the information provided, the error shows you initialize the myindexes inside the definition of a class.
  If so, you have to either define it as static or initialize it in a function, e.g. constructer.
  

  And could you also help me please to correct the errors as I am still getting. I don’t know what to do with it.

  There are too many errors. Actually, you can find all the reference of the error message form MSDN library, the error message tell you
  what is exactly problem you have.  I will provide some comments here based on your error message.

  >error C2061: syntax error : identifier ‘MENUITEMINFO’

  C2061: The compiler found an identifier where it wasn’t expected. Make sure that identifier is declared before you use it. See my first
  post.

  >sValue = safe_cast<String>(oRegKey->GetValue(«Proxy»));

  >error C2682: cannot use ‘safe_cast’ to convert from ‘System::Object ^’ to ‘System::String’
  

  >error C2440: ‘=’ : cannot convert from ‘System::String’ to ‘System::String ^’
  

  Try safe_cast<String^>.

  >if (GetHTMLPage(«http://www.whatismyip.com» + ProxyIP->Text, AutomaticCheckbox->Checked, Address->Text, ((Microsoft::VisualBasic::Information::IsNumeric(Ports->Text))

  >error C3083: ‘Information’: the symbol to the left of a ‘::’ must be a type

  >Microsoft::VisualBasic::Interaction(Application::ProductName, «Settings», «Address», Address->Text);

  >error C2039: ‘Interaction’ : is not a member of ‘Microsoft::VisualBasic’

  Please double check if you have add the Microsoft.VisualBasic assembly in project properties pages.
  

  The rest of errors, without code, it is hard to offer the solution for you. However, it is not really hard to fix the error you have
  after get meaning of each error code. More information about how to get help on a particular error message, please check
  http://msdn.microsoft.com/en-us/library/8x5x43k7.aspx .

  >>Most of the errors I am getting are the images, so I would like to add the images in my application resources, but I don’t know
  how to use the properties to read the images from the resources.

  In VC++ /CLI you need to create a Resource Manager object to load the objects from the resource file. Here is the example: suppose the
  application is called MyApplication and resource file is Form1.resx. In the form, we have created an image resource called Image1 and we use a Picture box control (picturebox1) to show the image. the code is look like following:

  System::Resources::ResourceManager^ resources =
  

                      
  gcnew System::Resources::ResourceManager(«MyApplication.Form1», System::Reflection::Assembly::GetExecutingAssembly() );

             
  this->pictureBox1->Image =

                 
  cli::safe_cast<System::Drawing::Image^>(resources->GetObject(«Image1»));

  Hope the information helps.

• >Don’t tell me that if I should buy a book or do a research.

  That was Yi’s advice, not mine. But I agree 100%.

  >These requirements would not help me to get anywhere, the
  >forums are the only place to go.

  Are you saying that if these forums didn’t exist you wouldn’t
  be able to complete a program? Forums and newsgroups exist to
  help solve problems which lend themselves to relatively brief
  answers. They are *not* a substitute for in-depth learning
  which can only come from concentrated study via books, courses
  or tutorials. Even the experts and gurus acquired much of their
  knowledge that way, plus studying the documentation and praxis.

  With respect to your long list of errors, you should be aware
  that it often happens that one error in the code spawns a
  plethora of error messages. The compiler’s parser can lose
  its way and start spewing out messages because it’s lost
  its way. That’s why it’s usually a good idea to attack the
  first errors and see if the others go away or change. Looking
  for others to give you definitive answers to all of the messages
  from a single compile is unrealistic.

  >String ^six = «6.»;

  >if (six = a->Length < 2 || String::IsNullOrEmpty(a[2]))

  >Errors: error C2440: ‘=’ : cannot convert from ‘bool’ to

  >if six statement.

  What exactly are you trying to do with this statement?

  >if (six = a->Length < 2 …

  Why are you *assigning* something to «six» here?

  The error is telling you that the expression
  a->Length < 2
  returns either true or false (a bool). But variable «six»
  is a String object. So you can’t do that assignment. You
  can’t store a bool into a String.

  Rethink what you’re trying to do and fix your code.

• Hello,

  >>Error: error C2248: ‘MyApplication1::Form1::MENUITEMINFO’ : cannot access private class declared
  

  Make sure the class MENUITEMINFO is defined as public and can be access by the GetMenuItemInfo function. E.g.

  public ref class MENUITEMINFO {

     
  public:

         
  int cbSize;

         
  int fMask;

         
  int fType;

         
  int fState;

         
  int wID;

         
  int hSubMenu;

         
  int hbmpChecked;

         
  int hbmpUnchecked;

         
  int dwItemData;

         
  String ^dwTypeData;

         
  int cch;

     
  };

   [System::Runtime::InteropServices::DllImport(«user32″, EntryPoint=»GetMenuItemInfo», ExactSpelling=false, CharSet=System::Runtime::InteropServices::CharSet::Auto,
  SetLastError=true)]

   static int GetMenuItemInfo(IntPtr hMenu, int uItem, bool fByPosition, MENUITEMINFO ^%lpmii);

  >>Errors: error C2440: ‘=’ : cannot convert from ‘bool’ to ‘System::String ^’ <—— the error are highlighting on if six statement.

  six = a->Length < 2 means you are assigning a Boolean value to a string, which is not valid. For the if statement, it requires the Boolean value. Do you want
  to handle the following condition? the length of the string six equals a->length and a->length is less than 2 or String::IsNullOrEmpty(a[2]), if so, the if statement should looks like if(six->Length == a->Length && a->Length <2 ||
  String::IsNullOrEmpty(a[2])).

  property Microsoft::VisualBasic::MsgBoxResult QuitMe

   
  {

     
  Microsoft::VisualBasic::MsgBoxResult get()

     
  {

       
  return m_Result;

     
  }

  >>Errors: error C2664: ‘void System::Windows::Forms::Control::Text::set(System::String ^)’ : cannot convert parameter 1 from ‘int’ to ‘System::String ^’ <—-

  This message shows you are pass a integer to a function which requires a String. I think the problem statement is ProxyPorts->Text = 0. If you want to pass a
  empty string, try “” or nullptr.

  Do you forget to include form1.h file in a class where you want to use Form1?
