Ask windows API applications how to call class objects

Question

0.00/5 (No votes)

See more:

Under a vc.net project, windows are drawn through windows api.
At this point, I added a class testClass to my project, which is a window.
Normally you should write code like this:
TestClass ^ frmTest = gcnew testClass (filepath);
FrmTest - > eReLoadFile += gcnew EventHandler (this, & Form1:: frmTest_eReLoadFile);
FrmTest - > ShowDialog ();
But how should Win32 applications be expressed?

What I have tried:

TestClass ^ frmTest = gcnew testClass (filepath);
FrmTest - > eReLoadFile += gcnew EventHandler (this, & Form1:: frmTest_eReLoadFile);
FrmTest - > ShowDialog ();

Compile error

Error 413 Error C2061: Syntax Error: Identifier "testClass"

1. if this is managed C++/CLI you should tag your question accordingly; this is not native C++ code
2. Your first line reference two different symbols, TestClass and testClass - which is it? symbols in C++ are case sensitive, and I would assume that extends to managed C++/CLI

You code is for Windows Forms, Win32 (Winapi) applications are quite different beasts (see, for instance Module 1. Your First Windows Program - Windows applications | Microsoft Docs[^]).

Solution 2

You made some typo (used small letters) in your code, and used later big letters

C++

TestClass ^ frmTest = gcnew TestClass (filepath);
frmTest - > eReLoadFile += gcnew EventHandler (this, & Form1:: frmTest_eReLoadFile);
frmTest - > ShowDialog ();

That doesnt like the compiler!!!

Pay more attention to details. Every bit counts ;-)

You forgot the second one has a small t in the question.
