Login Form C++ --->
Welcome to C++ Form Programming using Visual Studio 13 1. Open Visual Studio 13. 2. Go to File->New->Project. 3. Go to Visual C++ and choose CLR Empty Project. 4. After this go to : 5. Go to Visual C++ -> UI -> Select Windows Form. Will Look like this -> 6. Now Right click on Project<your project number> ( mine is Project6 so i will select Project6) and select properties and do same as me. 7.

Now, select Advanced, An Entry point row will come in menu and type "main" (without quotes). 9. Click Apply and Ok. 10. Now select your .cpp file from solution explorer in the right. in my case its "MyForm.cpp" 11.Then type this code in your cpp file. #include "MyForm.h" using namespace System; using namespace System::Windows::Forms...
My form is not building. It shows building error after writing the code you have written. Though I have included fstream as my header file, it is not recognizing "ifstream" and "getline".
ReplyDeleteThese are my header files:
#include
#include
#include
#include
This is my code:
//lets create a funtion
String^ userRAW = textBox1->Text;
String^ passwordRAW = textBox2->Text;
//Now we will convert
String user = msclr::interop::marshal_as(userRAW);
String password = msclr::interop::marshal_as(passwordRAW);
// Now we will check the info with the files if they are corect or not..//
ifstream readuser;
ifstream readpass;
readuser.open(user + ".txt");
readpass.open(user + "pass.txt");
String getpass;
getline(readpass, getpass);
if (getpass == password && readuser.is_open())
{
MessageBox::Show("Access Granted!\nAccount opened!");
}
if (getpass != password && readuser.fail())
{
MessageBox::Show("Access Denied!\n");
}
The dialogue box shows:
There were build errors. Would you like to run the last successful build?
What should I do now?
These are my header files as it did not appear in the last comment:
