Ну уже сами разбирайтесь что не то. Вы написали какая у вас ошибка — я ответил. Или вы скопипастили пример и даже не знаете какие параметры этой функции передать? Добавлено через 58 секунд
и почему такие числа?? Метод тыка

entry point must be defined
The linker did not find an entry point, the initial function to call in your executable. By default, the linker looks for a main
or wmain
function for a console app, a WinMain
or wWinMain
function for a Windows app, or DllMain
for a DLL that requires initialization. You can specify another function by using the /ENTRY linker option.
This error can have several causes:
- You may not have included the file that defines your entry point in the list of files to link. Verify that the file that contains the entry point function is linked into your app.
- You may have defined the entry point using the wrong function signature; for example, you may have misspelled or used the wrong case for the function name, or specified the return type or parameter types incorrectly.
- You may not have specified the /DLL option when building a DLL.
- You may have specified the name of the entry point function incorrectly when you used the /ENTRY linker option.
- If you are using the LIB tool to build a DLL, you may have specified a .def file. If so, remove the .def file from the build.
When building an app, the linker looks for an entry point function to call to start your code. This is the function that is called after the app is loaded and the runtime is initialized. You must supply an entry point function for an app, or your app can’t run. An entry point is optional for a DLL. By default, the linker looks for an entry point function that has one of several specific names and signatures, such as int main(int, char**)
. You can specify another function name as the entry point by using the /ENTRY linker option.
Example
The following sample generates LNK1561:
// LNK1561.cpp // LNK1561 expected int i; // add a main function to resolve this error

начал учить плюсы и проблема на первой же компиляции. на форме есть 2 текстбокса и кнопка. по идеи когда жмякаю на кнопку то текст из первого бокса переходит во второй.
private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e){ textBox2->Text = textBox1->Text;}
звучит просто, но у меня какаято непонятная ошибка- "Ошибка 1 error LNK1561: Єюўър тїюфр фюыцэр с√Є№ юяЁхфхыхэр c:UsersАдминdocumentsvisual studio 2013ProjectsПроект1Проект1LINK Проект1"
Помогите новичку.

Вы сделали немного не то. После добавления формы в проект у Вас должен был появиться файл MyForm.cpp. Откройте его и добавьте следующий код:
#include <Windows.h> using namespace Имя_Вашего_Проекта; int WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int) { Application::EnableVisualStyles(); Application::SetCompatibleTextRenderingDefault(false); Application::Run(gcnew MyForm); return 0; }
В строке «using namespace» необходимо указать название пространства имен, в котором объявлен класс формы (по умолчанию мастер называет его так, как называется проект).
Цикл обработки сообщений, запускаемый в методе Run, обеспечивает работоспособность Вашего интерфейса пользователя (формы).
Если сообщение помогло Вам, пожалуйста, не забудьте отметить его как ответ данной темы. Удачи в программировании!

If you a developer using Visual Studio for writing code, then you may encounter the below error at some point of time.
LINK : fatal error LNK1561: entry point must be defined
The error is self-explanatory but you must know how to fix it. If you are facing this fatal error LNK1561 error, you are at the right place. I will share the steps you can follow to resolve this Visual Studio error. Typically the error can appear on any version of Visual Studio and the below steps are applicable on all versions of Visual Studio IDE.
Reason:
The error LINK : fatal error LNK1561: entry point must be defined” appears when you are trying to build the code. The VS linker does not find the entry point function in your code; so it can not call your code.
There can be multiple scenarios when you can get this error. In this article, I will share 3 common checks that you can verify in your project configuration to make sure the error does not appear.
Fix #1:
In the first troubleshooting step, you need to know the intent of your code. If you have written the code to build a .dll or .lib; and your project settings is configured as .exe, then you will get this error.
You need to change the “Configuration type” from exe to dll or lib.
- Right-click on the project (not on the solution) and go to properties.
- Under General section, look for the “Configuration type” field.
- Change the type from Application (.exe) to Dynamic Library (.dll) or Static Library (.lib) based on your code.
- Click on OK to save the changes.
- Clean the project and build it again.
Fix #2:
If the intent of your code is to build an exe, then the Fix #1 does not hold good. If you are creating a console application, the linker looks for main function and for Windows application, it expects WinMain function to be present as entry point to your code.
- Go to project properties by right clicking on the project and selecting properties from the list.
- Under Linker → Advanced section, check the “Entry Point” field.
- If the field is empty and you have main/WinMain present as the entry point, the issue should not appear.
- In case, you face the same error, you can manually update the Entry Point to main/WinMain based on your project type.
Fix #3:
If you have a different entry point function other than main or WinMain, you need to update the function name in the “Entry Point” field.
- Right-click on the project and go to properties.
- Under Linker → Advanced section, update the “Entry Point” field to your function name.
Final words:
That’s it. These are the only possible steps to fix “fatal error LNK1561: entry point must be defined” error in Visual Studio. I hope your issue is not resolved. Do share your comments below and any tips and tricks you followed to help other developers.
Cheers !!!
