C Sharp :: Display SQL Database Record In List View Using C#
Oct 6, 2012
I want to display the content of my database in list view. The table has 5 columns however when I tried this code
string view = "Select * from cust_infor";
SqlCommand cmd = new SqlCommand(view,FL.clsconnection.opencon());
SqlDataReader dr = cmd.ExecuteReader();
listView1.Items.Clear();
while (dr.Read()) {
listView1.Items.Add(dr[0].ToString()).SubItems.Add(dr[1].ToString());
}
It limits the display to 2 columns. List view will only show the first 2 columns. The code above won't let me add more indexes or subitems. Only up to 2 columns.
I want to display data from text file in list view and in tree view root will be file name, but i dont know how to do it, the problem is with displaying text file data in list view, i don't know anything about that. text file data is very simple. It is just a square matrix of double values like:
I have patient_table in the database. which contain Id, name ,Image & other fields I have inserted the image in the Byte form in the database.Now i want to display all records in the Datagrid view in windows Form.
i am able to display id & Name & all fields but unable to display the image of a patient in the datagrid view.
I put all the records in the genric list:-
public static List<Personal_Details> AllMembers() { List<Personal_Details> listMembers = new List<Personal_Details>(); Personal_Details pDetails; try { String Constring = ConnectionString.dataBaseConnectionString;
[code]...
i am unable to write the code for displaying the image on data gridview.
I am unable to find the solution for binding the image field in the datagrid view.
And how to rewrite the code so that it display the MySQL table data for a specific user I already have a string called username and that stores the username entered on the login form. I want the code to use the username string to search for the name and display that users info.
My table contents are: username First name Last name Position Employee Id Airline
I am working on a windows application that is for make a time schedule for all staff. i am using two gridview one for all staff names from employee table , and second is for time schedule, time schedule DGV is like 6to7 , 7 to8...12to1,... 5to6 columns . when user will select like 7to8 , 8to9,9to10, columns with holding ctrl key , thn i have to assign some work beteen these time for 3 hours. So i have to get multiple columns from Gridview.
I have a listview in my Windows Forms Application and I am having some trouble wrapping my mind around how I can get a number to increment in column 2 for each line item that is added. The reason that I want to do this is because this number will later be added to a set of soft fonts, which requires a unique Font ID.
Here is what I have and where I am stuck.
foreach (string fontFileName in ofd.SafeFileNames){ //Add a line in the list view for each selected file. Don't allow for the same file to appear twice. if (listView1.FindItemWithText(fontFileName) == null){ listView1.Items.Add(fontFileName);
I have an application in C sharp that searches for a record in a sql database using a datetimepicker,the output is displayed in a datagridview.When I execute it I got a blank datagridview with empty columns.I can not view the content and I don't get any error message.
Here is my code:
DataTable dt=new dataTable(); SqlDataAdapter sda=new sqldataadapter("select * from Delivery where convert (char(20),Delivery_Date,112)='"+ dateTimePicker1.value.Date,con); //con is sqlconnection Sda.Fill(dt); Datagridview1.DataSource=dt;
How to validate the data if the data already exist in the table record in c#?
For example I wanted to add the student roll no. if roll no. is 134 and if we are adding rollno. 134 student then we get the warning like roll no. 134 is already exist ....
I am trying to complete this program and as far as I am aware, the only thing not working correctly is populating the listview with my data. I've been stressing over this for a few days and achieving no success. I have to load data from two text files (incidents.txt and technicians.txt), then use a query to populate a listview with all incidents that have been closed. Also, I have to use LINQ for this assignment, so I cannot change anything that would alter my use of that. I'm thinking that perhaps the problem is with my code in form1.cs?Included are all my classes,txt files, etc.

How would I go about selecting a subitem in a listview control with just pure Win32 API? I know it's possible with MFC... but I can't use MFC for this project. Right now, when you click on a subitem , it selects only the first column of the row . I used the following by referring internet. But its not working.
HTML Code: iSlected=SendMessage(hList,LVM_GETNEXTITEM,-1,LVNI_FOCUSED|LVNI_SELECTED); ListView_SetItemState(hList,iSlected,LVIS_FOCUSED|LVIS_SELECTED,0x000F);

I have a program I have been working on where the user selects a date and enters the number of days to be viewed in the Calendar.cshtml view. This input renders another view (Update.cshtml) that contains two date picker boxes, one that should contain the selected date and the second one that should contain the calculated date. I am having an issue getting the date selected in the first view to populate to the first date block on the second view as the default and getting the calculated date to populate the second date block in the Update.cshtml view. In addition given the two dates, I would like to generate a calendar, which is why I chose the date picker approach and setting static dates.
Here is my code:
**CalendarController:**
using System.Web.Mvc; using VanickCalendarApp.Models; using System; namespace VanickCalendarApp.Controllers { public class CalendarController : Controller {
The main question how to fully traverse/circumvent through all TreeView, for transforming Tree structure into a Table structure.
I want to note that the TreeView may contain a different number of branches, with different depths and different names.
I found a lot of information how to populate TreeView e.g. from DataTable, but I didn't found information how to recursively traverse/circumvent a TreeView and populate/fill data e.g. to DataTable.
As sample I have following TreeView:
Aaron -Baldwin --Caleb ---Dale --Earl -Fabian Gabriel -Harold -Ian
Necessary to convert the TreeView into e.g. DataTable:
I just wanna update my database with one click only.
I do for update my database from datagridview1 but it shows a error like this :
Unhandled exception has occurred in your application . If you click Continue, the application will ignore this error and attempt to continue. If you click Quit,the application will close immediately.

I'll work soon on a program that should take the finger print from a reader and save it in sql server to determine employees's presence and leaving. My questions are:
1- Is the written code differ from one reader to another? or any code apply to all readers?
2- I knew that i should take the image and save it in varbinary in sql server, but how i shall take it?
3- Libraries i should use in visual studio 2010 and c#?
4- should i write license with a definite number of fingerprints save?
5- when i try to approve an employee pressece (by taking his fingerprint), shall i go directly to his id in SQL server and compare his fingerprint stored with the new one entered, OR i Should take the fingerPrint and search for it?
