Configuration Function "How to link different .exe program" for a .txt file

Hi GOOD DAY!

I a a newbie to C++.
I got a question. Could you give me some suggestion?

i am modify a small edit tool now.
How to improve a new function that user could configure a different edit tool which user installed at their local OS to Open "*txt" file?
My program default take us Notepad to open *.txt file.
But i want to imporve the function which user could open the explore and select one edit tool(such as my local editplus) ,Save the change. and user coudl open view file (.txt) with the new editplus now.


(I find that "WinSCP" improved the fucntion, it is really very cool.)

Thanks!

Does your program call notepad explicitly? If so, then don't do that.

Does your program call on the OS to use the default text editor? If so, then you'll have to change the default text editor in the OS.

I have my tool source code writed by my colleague, but he already quit now.
i just want modify source code and improve the new feature.

i don't want to modify OS and set the default text ediotr. for the tool also will release to more user, i juat want to enhance the new open .txt function.

Current function, the log.txt will be open by notepad defaultly

Code:

---



void CSECS_AMECDlg::OnBnClickedButtonViewLog()
{
        // TODO: Add your control notification handler code here
        CString logFilePath(Util::GetModulePath().c_str());
        logFilePath += "\\\secslog.txt";
        ShellExecute(NULL,NULL,logFilePath,NULL,NULL,SW_SHOWDEFAULT);
}

---

i want to call OnBnClickButtonViewLog() and jump our a configuration windown, user could set the default view log tool to editplus.

My OS is WINXP and my C++ IDE is Visual Studio 2005 Pro

:)

thanks!

So, you can't use ShellExecute to do that, you need to use CreateProcess Function (Windows) or something like that. And of course, you pass along the configured editor program. You may also want to have a fall-back option: if there is no editor configured, or if the CreaeteProcess fails, you will want to call ShellExecute to use the system configured text editor.

Why is the tool passing off the editing to another editing program in the first place? Should not an edit tool....support editing?

// Q. why i need the new feature (e.g. Configure view log tool from notepad to editplus)
// A. - Mainly for performance reason. Now the tool will creat daily YYYYMMDD.TXT log file realtime, and sometime the log file is bigger than 10M. when we click log view button (default notepad launched now), it will take a long time to open it. if i open the log file folder from the windows explorer with Editplus, it is very fast:-)
Another reason, the tool will be realeased to another lab group user. There is no Editplus in their OS. Based on this condition, i plan to develop the new function still support open the Log file via Notepad defaultly.

// i just tried to take use ShellExecute()... and i will try to learn CreateProcess Function (Windows) too. :-)
-----------------------------------------------------
Menu Click To Configuration.
I just try to save the Editplus Folder Path to a config.ini file.

Code:

---


void CSECS_AMECDlg::OnMenuConfigviewlog()
{
        // TODO: add user configuration for view log edit tool selection
        // m_ViewLogDlg.MoveWindow(100, 100, 300, 300);

                CFileDialog m_ViewLogDlg(
                TRUE,
                "exe",
                NULL,
                OFN_FILEMUSTEXIST | OFN_PATHMUSTEXIST | OFN_HIDEREADONLY | OFN_NOREADONLYRETURN,
                "Exe files (*.exe)|*.exe||");

                // Set initial path
                m_ViewLogDlg.m_ofn.lpstrInitialDir = "c:\\Program Files";

                // Set title of dialog
                m_ViewLogDlg.m_ofn.lpstrTitle = "Like to your favorite view tool . e.g. editplus...";

                // Show file open dialog
                if (m_ViewLogDlg.DoModal() == IDOK)
               
                // Get selected path name
                CString editToolInstallPath = m_ViewLogDlg.GetPathName();
               
                // Save the Path to Config.ini
                ofstream SavePath("config.ini ");
                SavePath << m_ViewLogDlg.GetPathName();
                SavePath.close();
               
               

}

View Log Button Function.

Code:

---

void CSECS_AMECDlg::OnBnClickedButtonViewLog()
{
        // TODO: Add your control notification handler code here
        CString logFilePath(Util::GetModulePath().c_str());
        logFilePath += "\\\secslog.txt";
       
        CString EditToolConfigPath;

        // debug need

        if (EditToolConfigPath == "")
        // View Log with Notepad defaultly
        {
                ShellExecute(NULL,NULL,logFilePath,NULL,NULL,SW_SHOWDEFAULT);
        }
        else
        // View Log With Editplsu, UltraEdit, etc...
        // Should be more flexiable, no hardcode - the 3rd part edit tool path should be replaced!
        {
                // editToolInstallPath = "c:\\Program Files\\EditPlus 3\\editplus.exe";
                ShellExecute(NULL,NULL,EditToolConfigPath,logFilePath,NULL,SW_SHOWDEFAULT);
        }
}

------------------------------------------------------------------
i tested the top related function, it worked well.
But i still have two problems.
ONE:
I can't save the Edit Tool Name Path to local .INI config file, i don't know why?

TWO:
I creaed a small script to try the C++ IO function.
Why it is Octal(e.g. 0015BD68 ) format record from my config.ini ?

Code:

---

#include "stdafx.h"
#include "atlstr.h"

#include <iostream>
#include <fstream>
using namespace std;

int main () {
 
        CString NamePath;
        NamePath = "C:\\Program\\Editplus 3\\editplus.exe";
        ofstream f("config.ini");
        f << NamePath;
        f.close();
        return 0;
}

---

Write the editplus path to the config.ini code test pass.

Code:

---

// IOFileTestProj.cpp : main project file.
#include "stdafx.h"

#include <iostream>
#include <fstream>

using namespace std;

void main()
{
        char PathDirectory[] = "C:\\Program\\Edit Plus3\\Editplus.exe";

        ofstream SaveFile("config.ini");
        SaveFile << PathDirectory;
        SaveFile.close();
        // return 0;

}

---

--------------------------------------------------------
Read the editplus path from the config.ini code sample test pass too.
[code]
void main() //the program starts here
{

ifstream OpenFile("config.ini");
char ch;
int i;
while(OpenFile >> ch)
{
cout << ch;
}
cout << endl;
OpenFile.close();

cin >> i;
}


--------------------------------------------
i will try to integrate the sample code to my tool :-)
project on going ^_^ ....

fyi
My ugly code, but functional now.
Cheer!
