3аполняю таблицу 3начениями, ра3 от ра3у часть английских слов вводится, а сейчас как на картинке

#pragma once

#include <ctime>
#include <cstring>

Почему не используешь QString?

[Евгений Петряев]

Александр Ананьев, и3 ба3ы данных дергаю там только char*

[Александр Ананьев]

Евгений Петряев, из char* легко получается QString

[Евгений Петряев]

Александр Ананьев, а это по вашему что?
qstr = QString::fromStdString(v[i][j]);

[Александр Ананьев]

Евгений Петряев, я про это
char* status и тд

[Евгений Петряев]

Александр Ананьев, ну вот

Task* task_ = new Task();
    for (int i = 0; i < nrows; i++)
    {
        task_->id = atoi(PQgetvalue(res, i, 0));
        task_->task = PQgetvalue(res, i, 1);
        task_->parentTask = atoi(PQgetvalue(res, i, 2));
        task_->executor = PQgetvalue(res, i, 3);
        char* ddl = PQgetvalue(res, i, 4);
        ddl[4] = ddl[7] = '\0';
        task_->dateDeathLine->tm_year = atoi(&ddl[0]) - 1900;
        task_->dateDeathLine->tm_mon = atoi(&ddl[5]) - 1;
        task_->dateDeathLine->tm_mday = atoi(&ddl[8]);
        ddl = PQgetvalue(res, i, 5);
        ddl[4] = ddl[7] = '\0';
        task_->dateStart->tm_year = atoi(&ddl[0]) - 1900;
        task_->dateStart->tm_mon = atoi(&ddl[5]) - 1;
        task_->dateStart->tm_mday = atoi(&ddl[8]);
        task_->status = PQgetvalue(res, i, 6);

        task_->oldtask = PQgetvalue(res, i, 7);
        cout << " Id: " << task_->id;
        cout << " Task: " << task_->task;
        cout << " Parent: " << task_->parentTask;
        cout << " Executor: " << task_->executor;

        char* date_string = new char[50];
        strftime(date_string, 50, " %Y-%m-%d", task_->dateDeathLine);
        cout << " DeathLine: " << date_string;

        strftime(date_string, 50, "%Y-%m-%d", task_->dateStart);
        cout << " Start: " << date_string;
        cout << " Status: " << task_->status;
        cout << " Oldtask: " << task_->oldtask << endl;
        vTask.push_back(*task_);
    }

Тупанул надо было копировать строки, а не присваивать

Task* task_ = new Task();
    for (int i = 0; i < nrows; i++)
    {
        task_->id = atoi(PQgetvalue(res, i, 0));
        strcpy(task_->task , PQgetvalue(res, i, 1));
        task_->parentTask = atoi(PQgetvalue(res, i, 2));
        strcpy(task_->executor , PQgetvalue(res, i, 3));
        char* ddl = PQgetvalue(res, i, 4);
        ddl[4] = ddl[7] = '\0';
        task_->dateDeathLine->tm_year = atoi(&ddl[0]) - 1900;
        task_->dateDeathLine->tm_mon = atoi(&ddl[5]) - 1;
        task_->dateDeathLine->tm_mday = atoi(&ddl[8]);
        ddl = PQgetvalue(res, i, 5);
        ddl[4] = ddl[7] = '\0';
        task_->dateStart->tm_year = atoi(&ddl[0]) - 1900;
        task_->dateStart->tm_mon = atoi(&ddl[5]) - 1;
        task_->dateStart->tm_mday = atoi(&ddl[8]);
        strcpy(task_->status , PQgetvalue(res, i, 6));

        strcpy(task_->oldtask , PQgetvalue(res, i, 7));
        cout << " Id: " << task_->id;
        cout << " Task: " << task_->task;
        cout << " Parent: " << task_->parentTask;
        cout << " Executor: " << task_->executor;

        char* date_string = new char[50];
        strftime(date_string, 50, " %Y-%m-%d", task_->dateDeathLine);
        cout << " DeathLine: " << date_string;

        strftime(date_string, 50, "%Y-%m-%d", task_->dateStart);
        cout << " Start: " << date_string;
        cout << " Status: " << task_->status;
        cout << " Oldtask: " << task_->oldtask << endl;
        vTask.push_back(task_);
    }
