Creating a Folder

**Junior89** · 11-06-2004

Please help.

I am making a program for my dad's small busieness, im new to this thing. I need to make a program that will create a folder on the C drive this folder is used with this program but i want the program to set everything up instead of someone else having to.

Thanks,
DJD

Use the function CreateDirectory()

**~~cgod~~** · 11-06-2004

Code:

#include <windows.h>
#include <iostream>
#include <dir.h>
using namespace std;
int main()
{
    if(mkdir("c:\\Documents and Settings\\wmorrish\\Desktop\\new folder")!=0);
    {
        cout<<"directory not created"<<endl;
    }
     cout<<"directory created"<<endl;
}

cgod > I'm not sure where dir.h is coming from, but the CreateDirectory() API function is the correct way to create a directory on windows machines.

Could you use CreateDirectory() in an example?

**~~cgod~~** · 11-06-2004

so it should be something like?

Code:

#include <windows.h>
#include <iostream>
using namespace std;
int main()
{
   bool WINAPI;
   HWND hwnd = CreateDirectory("New Folder",0,0);
   if(!hwnd)
   {
       cout<<"directory creation failed"<<endl;
   }
   else
   {
       cout<<"Directory created"<<endl;
   }   
}

but im getting a strange error

Code:

 internal compiler error C:\Documents and Settings\wmorrish\Desktop\New Folder\main.cpp:7 Segmentation fault

No, there are several errors in your code.

Here is an example on how to use the function:

Code:

#include <windows.h>
#include <stdio.h>

int main()
{
	if(CreateDirectory("C:\\temp",0))
		printf("Directory created\n");
	else
		printf("Directory creation failed\n");

	return EXIT_SUCCESS;
}

Hey guys i got another problem with this prgram. The directory is created both ways that you guys said but i am having another bigger problem. My program has 4 options, OPen a file, Create a File, Help(Irrevelvant), and Quit. The program writes the code sometimes and reads it sometimes. Sometimes i get a KERNEL32.dll error. Heres the code, maybe you guys could help:

Code:

...Creating the folder (Works fine)...

int x;
x=1;
while(x=1){
   ...(some menu stuff)
   int choice;
   cin>>choice;
   cin.ignore();
   if(choice==1)   // Read File
   {
      char entryn[20];
      char prevname[50];
      cout<<"Entry Name: ";
      cin.getline(entryn,20);
      strcat (prevname, "C:/ProfilesProg/");
      strcat (prevname, entryn);
      ifstream entry(prevname);
      cout<<"\n***File Start***\n\n";
      char ch;
      while(entry.get(ch)){
         cout<<ch;
      }
      cout<<"\n\n***End of File***"\n";
      cin.ignore();
      entry.close();
      continue;
   }

   else if(choice==2){     //Write a File
      cout<<"Name of Entry: ";
      char entrynew[20];
      char entryname[50];
      cin.getline(entrynew,20);
      strcat (entryname, "c:/ProfilesProg/");
      strcat (entryname, entrynew);
      char notes[1000];
      cout<<"Enter Information.\n\n";
      ofstream newentry(entryname);
      newentry<<notes;
      newentry.close();
      continue;
   }
   
    ...Nothing to do with the problem

Please if you dont mind correct any mistakes that have been made and comment on the code.

Thanks so much!

Code:

while(x=1){

you probably mean:

Code:

while(x==1){

Code:

strcat (prevname, "C:/ProfilesProg/");

strcat() is used to append a string at the end of another string. Since prevname has not been initialized to a string in this case, there is a high probability of it giving you an error. In order to initialize the array to a string, do the following:

Code:

strcpy(prevname, "C:/ProfilesProg/");
