I want some simple code which will return only the DriveInfo from one drive. I have the below code but it isn't displaying what I expect it to display, I have a feeling i'm using Linq wrong!
var dname = from n in System.IO.DriveInfo.GetDrives() where n.Name == "F" select n.VolumeLabel;
richTextBox2.AppendText(dname.ToString() + "
");
The above should return the devices VolumeLabel which is in port F.
I am trying to query fields in a where clause using LINQ to SQL and for some reason I cannot figure out why it doesn't work:
var qryGetMonsterID = (from students in dbContext.tblStudentPersonals where (students.givenname.Equals(fn)) && (students.familyname.Equals(ln)) && (students.middlename.Equals(mn)) && (students.email.Equals(e)) select students);
The returned SQL Syntax is:
SELECT [t0].[monsterid], [t0].[givenname], [t0].[middlename], [t0].[familyname], [t0].[homeaddress], [t0].[city], [t0].[state], [t0].[postal], [t0].[primaryphone], [t0].[secondaryphone], [t0].[email], [t0].[username], [t0].[lastmodified], [t0].[modifiedby] FROM [dbo].[tblStudentPersonal] AS [t0] WHERE ([t0].[givenname] = @p0) AND ([t0].[familyname] = @p1) AND ([t0].[middlename] = @p2) AND ([t0].[email] = @p3)
Not sure but the values for middle name could be null - because not everyone has a middle name and the same is true for e-mail.
Each Element named Bookmark has 4 attributes, Name, Folder, Time, and Chapter.
I'd like to be able to just put all of them in ONE type of container, without making multiple lists... Is there any way, using Linq to XML, to maybe add all of these values to a Tuple?
I am trying to query dates between two textbox values converted to datetime in C#. The dates are returning in the correct datetime and no conversion problem exists there.
However when I run the below LINQ to SQL query in C# it returns no enumerable results. But if I take the below code:
DbCommand dc = dbHistoryContext.GetCommand(qryRes); Console.WriteLine(dc.CommandText);
and get the results as a string of text and cut and paste that into the SQL Server Management studio and execute it - then it works. What do I need to do to search between two dates so that it properly works. The field is of format Date in SQL Server if that matters and the fields being used to pass the information to it are DateTime. The compiler doesn't show any errors but it just doesn't return results.
var qryRes = (from res in dbHistoryContext.tblR where res.updateddate >= dtDateFrom.Date && res.updateddate <= dtDateTo.Date select res);
Employee 1/7-1/13 1/14-1/20 1/21-1/27 1/28-2/3 and so on... A sum of values for this 7 days B C D
I want to add all the values of Job1 for each employee in a time range which is one week starting from monday to sunday. How can I group the Job1 values week wise and store them in another datatable.
I would like to be able to safely eject a USB drive (in Windows) when user selects that drive in a listbox and clicks the Eject button in an MFC dialog app. Any functions or (link) that would be up to date (i.e. compatible with Windows 8)?
I have written some code to make two partitions in USB flash drive. When I ran it I am not able to make partitions on usb. What'll be the problem in this code.
Code: /-------------------INITIALIZE AND PARTITION-------------------------------// #include "stdafx.h" #include <Windows.h> #include <stdio.h>
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 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 ....
I am trying to write a to a specific sector in a flash drive. The problem is that it will only allow me to write to sectors 0 to 15. When I try sector 16 or higher nothing happens, but in sector 0 to 15 is is working fine.
#define BUFFER_SIZE 512 int main(void) { FILE *volume; int k = 0; long long sector = 0; char buf[BUFFER_SIZE] = {0};
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.
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.
Write a program that is able to save a list of items such as books, CDs, or DVDs and the items that are saved must have attributes associated with them. 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> #include <iomanip> using namespace std; int main () { const int arraySize = 10; int a[arraySize] = { 2, 6, 4, 10, 12, 89, 68, 45, 37 }; int i, hold;
