Programmatically Modifying A File On Windows Server 2008
Nov 23, 2009I have written a VB.NET 2008 application, incorporating Microsoft.Office.Interop.Excel, that modifies an existing Excel 2007 spreadsheet. It works perfectly on my WinXP development computer.When I upload the app to a Microsoft Web Server 2008, it opens the file and reads from the file, but when the app tries to save the file, it throws this exception:"System.Runtime.InteropServices.COMException (0x800A03EC): 'july2009.xlsx' is read-only. To save a copy, click OK, then give the workbook a new name in the Save As dialog box."The file is NOT read-only, nor is it opened by any other user or app.The app and the Excel file both reside on the D: (data-only) drive.My first instinct was to look at file permissions. When nothing else worked, I literally created a temporary Group, added EVERY user and security entity to it and granted the group full control of the entire D: drive. No luck.
Then I tried manually elevating the permission by running my app as administrator. No luck.Finally, I copied the file to my XP development computer and ran the app there. Of course it worked perfectly.Can anyone please tell me how to give my program permission to edit a file on Server 2008?

Adding And Deleting Controls Via Code?
Aug 14, 2011I am trying to create and remove a series of controls programatically. The user will have a numeric updown to pick a number. The program will then create a bunch of duplicate controls based on whatever number they pick on the fly.
Public Class Form1
Private Sub NumericUpDown1_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles numberDebts.ValueChanged[code].....
The creation part works just fine.As the number is toggled upward a new label is created.However whenever I remove labels it acts very strangely.The first time I bring it down it works just fine. Then the next 3 do nothing but the 4th removes another line.I can also toggle back and forth and it will eventually remove the label. So for example.
Starts with 1 selected - 1 label visible (1)
Change to 2 - 2 labels visible (1-2)
Change to 3 - 3 labels visible (1-3)[code]....
If I toggle back and forth between 2 and 3 eventually label 4 will go away.I want only 1- my numeric up down value to be displayed and have everything else after that removed.

Modifying Names And Data Via The App.config File?
Mar 23, 20111. The application's text box controls are entered manually in my.settings (e.g., tb1, tb2, tb3)
2. The application user "adds" a row of text boxes, which are iteratively assigned a name to match the above my.settings names
3. Upon "save" by user, the text in each text box is associated with its control (e.g., If cntl.Name = "tb1" then My.Settings.tb1 = cntl.Text)
4. The User needs to delete one or more rows previously added
Question:Under #4 of above, what is the best way to delete the rows and how can I use the app.config file to update the above data so I can reuse the named text boxes and keep everything sequential?

Get SQL Commands (adding, Updating, Deleting) To Work With A VB 2010 Database?
Feb 12, 2012My project involves making a table database that displays student number, surname, first name, homeroom, and grade avg. Through SQL commands, there must be functions to add, update, delete, search by field, and save records to the database.I have already set the database up just fine and displayed it in a DataGridView. Through the DataGridView, I was able to go to the "Add Query" area, and I successfully made the queries necessary for searching by field. However, when I try to do anything other than a search using the query builder (ie start my SQL command with INSERT INTO or DELETE FROM), I ultimately get the message "Failed to get schema for this query"For example, this SQL code (to add an entry to the database) worked when I was in the Query Builder (and the entry that it made is still in the database), but when I finally tried to confirm it, I got the "Failed to get schema for this query" message.Being unable to add entries to the database this way, I tried to do it with textboxes on a form. Each textbox will have one of the fields, and at the click of a button, they would be put into the table. My code is below. I do not know what is wrong withit. When I run it, my fields do not appear on the DataGridView immediately, but I must run the program again to see it. The time after, the entry is gone. So I am not sure how exactly such entries are to be saved.
