I am trying to save the excel file in D:/newfolder. but the file saving as newfolderFilename. The newfolder is already created in D drive. File save path i am getting from textbox ....
View 14 Repliesusing C++ how can i check the presence of a folder in a drive.
The path of the folder is available in a std::string like std::string path = "C:TestFolder";
there's a way to get a path to the recycle bin folder for a specific drive for the current user?
Say, on the input one provides "C:" and on the output you get "C:$Recycle.BinS-1-5-18"
I would like the user to insert a CD into their computer and click on an button on my application that allows them to read the CD-ROM and find a specific file type, e.g. csv, and then grab the info in the csv file.
I already have my StreamReader setup grabbing a filepath.
Now I am just wondering...how do I detect the CD-ROM and how do I grab the filepath of the only CSV file on the CD-ROM?
What's behind detecting a CD-ROM and grabbing a specific file type from a CD-ROM?
I heard about DriveInfo
However, that only allows me to detect a drive but not look at it's contents.
I want to read a file from my flash drive called text.csv. However, I cannot even open the port where my flash drive is connected. This is the code that I am using, but I get error since the first part. When I run the program it says "fopen Error". I am using Ubuntu 12.04.

I need a code in c++ . It should count the Files and Directories in root folder with every folder information i need the below information
1) no of files and folder
2) how many files are there in each folder
3) with size of every folder and files it contains
I am new in c++ ....
private String[] GetExcelSheetNames(string excelFile) {
OleDbConnection objConn = null;
SqlConnection objSqlConn = null;
System.Data.DataTable dt = null;
try {
[code].....
Now I can fatch all the excel sheet belongs to the Excel File.But How can I check "If and Only If the sheets are havin Underscore in their name(eg. student_data,teachers_data) then only the data of the sheets will populate in tha data base"
Currently I'm trying to do something extremely basic: delete or move a file
I have a mapped network drive (Y) where I have a file I need to move from one folder to another
First was doing the obvious:
System.IO.File.Move("Y:TempFile.txt", "Y:Temp2File.txt");
Not much to go wrong here, right? As long as I have the correct permission to write in the folders and the folders exists, this would normally go smooth. But for some reason it only copies the file. The source file still exists, but it has successfully copied the file to the destination folder. No exceptions has been thrown or anything... but the file still exists in the source directory
I then changed the code to the following:
System.IO.File.Copy("Y:TempFile.txt", "Y:Temp2File.txt");
System.IO.File.Delete("Y:TempFile.txt");
Console.WriteLine("See mommy, no Exceptions");
As expected the file copies correctly, but the delete command is completely ignored. The file is not deleted, but the Console.WriteLine command is called
I'm running the application as the logged in user. The user has permission to delete the file. If I try from Windows Explorer, the file is correctly deleted. Unfortunately my application refuses to delete the file and even worse, it will not even throw an Exception.
I have tried to use File.Copy and File.Move but non of them would work as I expected .....

For example a book has a title, author, publisher, and ISBN.I would like to create a program that is able to save the database of items to a file on the hard drive and also retrieve it from the hard drive.I have this for a start of how to set up a storing program.
#include <iostream>

using namespace std;
int main () {

I want to make a launcher for my program but the installation folder is different from one computer to another so I need a function or something that shows the path of the executable file.how to import a file from another folder.
#include<stdio.h>
int main(void)
{
FILE *fp;
*fp=fopen("C:Documents and Settings...something.txt","r");
}
You see I want to set the import path.
i get the name of file upon every OK click in the list of array.
i want the file name to be written in command prompt to install the file like
C:WindowsSystem32msiexec.exe filename.exe /quiet
fi is array representing the files
following is a code ..
foreach (FileInfo fiTemp in fi)
{
p2.StandardInput.Write("msiexec.exe ");
p2.StandardInput.Write(fiTemp.Name);
MessageBox.Show(fiTemp.Name);
}
Say, I have the "K: est del USB" folder.
Then I do the following:
Code:
SHFILEOPSTRUCT sfo = {0};
sfo.wFunc = FO_DELETE;
sfo.pFrom = L"K: est del USB";
sfo.fFlags = FOF_ALLOWUNDO |
[Code] ....
So when I run it, the SHFileOperation API shows this warning:
Are you sure you want to permanently delete this folder?
If the end-user clicks "No", SHFileOperation return 0x4c7, which I believe is ERROR_CANCELLED.
My question is, if I don't need any UI, how can I know that my file/folder will be permanently deleted vs. placed into the Recycle Bin?
Code:
#include<stdlib.h>
FILE *Ptr_file;
Ptr_file =fopen("output.txt", "w");
struct person {

int nDay[2],nMnth[2],nYear[4];

i'm kinda new to c#, i wanna create a program which will take few data from GUI and export it into an excel file. Another thing is how to modify the data displacement in that particular excel file?

View 7 Replies View RelatedI am currently having issues with the following code when trying to create a excel file using C#. This is the code that I have at the moment.
oXL = new Microsoft.Office.Interop.Excel.Application();
oXL.Visible = false;
oWK = (Microsoft.Office.Interop.Excel._Workbook)(oXL.Workbooks.Add(System.Reflection.Missing.Value));
oWK.SaveAs(path + "" + fileName);
oWS = (Microsoft.Office.Interop.Excel._Worksheet)oWK.Worksheets.get_Item(1);
oWS.Cells[1, 1] = "Student ID";
oWS.Cells[1, 2] = "Student Name";
oWK.Save();
The line that I am having issues with is
oWS = (Microsoft.Office.Interop.Excel._Worksheet)oWK.Worksheets.get_Item(1);
If I remove it, I am able to create and save teh workbook in the directory. However, I want to make some changes on a worksheet, and that is where the issue is. I have also tried using the line of code:
oWS = (Microsoft.Office.Interop.Excel._Worksheet)oWK.Worksheets[1];
This line had no luck either. The issue I am having is the error regarding InvalidOperationException: Dynamic operations can only be performed in homogenous AppDomain.

I'm writing a small function that gets as parameter a file's path and a folder's path, and copies the given file to that folder.
Code:
int copy_file(const char* source, const char* folder) {
char copy[PATH_MAX];
strcpy(copy, folder);
strcat(copy, "/");
strcat(copy, source);
[Code] ....
Basically, this function purpose is to make a backup of source in folder every X minutes (depending on user's input).
The problem is the second call to open():
This call attempts to open the file for writing, and creates it if it is not already exist.
It also truncates it before writing to it - and that's my concern:
Let's say this is the second time this function runs, so copy is already exist. open() will then truncate it, and then one of the system calls in the while loop fails.
In this situation, I might be left with no backup file.
The problem also arises for when source is a read-only file:
If source is a read-only file, and copy is not already exist (meaning - it's the first backup attempt), then everything's fine, but, if source is a read-only file and copy is already exist, then I have to first remove copy altogather, and make a fresh copy of source.
Making a backup with new name for copy every time copy_file() runs, will solve this problem, and how can this be accomplished?
I should say that I'd really prefer that copy and source will have the same names when copy_file() returns...
I am searching an API that can give me thumbnail(with large Icons) of all folders of all drive in Windows 7. Like
c:/--->Folder1,Folder2.....FolderN
d:/--->Folder1,Folder2.....FolderN
.
.
n:/--->Folder1,Folder2.....FolderN
How i can get associate thumbnail(with large Icons) of each folders of any of the drive.

The only Problem I have is that I need to know how to open a command window at the folder containing the .exe file(this program), inorder to enter the program name or arguments.
Scenario as below:
I have two module, A and B
Module A:
- A.cpp & A.h
Module B:
- B.cpp & B.h
and then for these two *.h file i put in another centralized folder call HeaderFile.
when I #include "B.h" from A.cpp, the compiler show me Error code C1083.
I want to delete the folder from the file system, but I am getting error of access permission.
I want to change the permission of the folder so my program can delete it.
The problem I am facing on google search is I am getting results mostly for MFC code which is windows specific. However, I want to write a code in core C++ that works on all platforms like unix and windows.
