Iltimos, menga qo'riqchilar bilan nima bo'lganini ayta olasizmi? Men bu xatolarni olaman:

Xulosa
Men C++ da Windows formasi bilan ishlash uchun Visual studio 2012 dasturidan foydalanaman. Men bir nechta shaklga ega bo'lishni xohlayman. Men Form2ni loyihalashtirdim va Form2.h ni Form1.h ichiga kiritdim. Lekin form2 ni ochganimda, u paydo bo'ladi va darhol o'chadi.
Bu mening kodim:
#include "Form2.h"
...
private: System::void button_Click(System::Object^ sender, System::EventArgs^ e){
Form2 frm2;
frm2.Show();
//this->Hide();
//this->Close();
}
foydalansam
this->Hide();
ikki shakl yashirinadi va agar men forma1ni yopsam
this->Close();
form2 ham yopiladi.
Shakllarni mustaqil ravishda ochish va yopishni xohlayman. Nima qilishim kerak?
Har qanday yordam minnatdor bo'ladi
Agar siz Visual Studio bilan ishlasangiz, barqaror sozlamalarni olish juda oson. Solution Explorer-da loyihani o'ng tugmasini bosing va Xususiyatlar-ni tanlang. Sozlamalar yorlig'ini tanlang va sozlamalar mavjud bo'lmasa, giperhavolani bosing.
Ilova sozlamalarini yaratish uchun Sozlamalar yorlig'idan foydalaning. Visual Studio Settings.settings va Settings.Designer.settings fayllarni yaratadi, unda ApplicationSettingsBase-dan meros bo‘lib qolgan singleton sinfi Settings mavjud. . Ilova sozlamalarini oʻqish/yozish uchun kodingizdan ushbu sinfga kirishingiz mumkin:
Properties.Settings.Default["SomeProperty"] = "Some Value";
Properties.Settings.Default.Save(); // Saves settings in application configuration file
Ushbu uslub konsol, Windows Forms va boshqa loyiha turlari uchun ham qo'llaniladi.
Sozlamalaringizning ko‘lami xususiyatini o‘rnatishingiz kerakligini unutmang. Agar siz Ilova doirasini tanlasangiz, u holda Settings.Default. faqat oʻqish uchun boʻladi.
Ma'lumotnoma: Qanday qilib: C# bilan ish vaqtida foydalanuvchi sozlamalarini yozish - Microsoft Docs
C# - Bir shakldan boshqa shaklga qiymatlarni yuborish
Buning bir nechta echimlari bor, lekin men foydalanadigan naqsh bu.
// Form 1
// inside the button click event
using(Form2 form2 = new Form2())
{
if(form2.ShowDialog() == DialogResult.OK)
{
someControlOnForm1.Text = form2.TheValue;
}
}
Va...
// Inside Form2
// Create a public property to serve the value
public string TheValue
{
get { return someTextBoxOnForm2.Text; }
}
