Unable To GRANT SELECT To A Table?
Jan 15, 2012
I have a program that I wrote that creates a database in SQL Server called States_02 as a sysadmin user. Later on I want to grant SELECT permissions to that database to another user, web I always get an error that it cannot find States_02 or I don't have permissions to do it. My Code:
Dim Conn As New OleDbConnection(ConnStr)
Try
Conn.Open()
[Code].....
The user has public and sysadmin server roles and is the same user who created the database. This user can also login to SQL Server and grant the permissions manually.

An unhandled exception of type 'System.InvalidOperationException' occurred in system.windows.forms.dllerror in line: dbAdp.Update(dbDset) in btnSave_Click, (elseif editflag = true) blockdescription: Update unable to find TableMapping['Table'] or DataTable 'Table'I was also wondering if I could simply use the ExecuteNonQuery for the delete statement, but since I've placed my data in a datarow, I'm not sure if i can actually use it. Any thoughts on this? Btw, this is my first time using a datarow, and I've recently been studying how to use ADO.net.
dr = dbDset.Tables(0).Rows(CurIndex)
dr.Delete()
dbAdp.Update(dbDset.Tables("addresses"))

In my application, I create data and log folders that must be shared by all users using this computer. I did a lot of research, and I found a function that is supposed to grant full access to every users of a folder and its children. However if right-click properties on my folder, the access is unchanged. ow should I grant full access to all users of a folder and its children (I don't care who created it, all users should be able to read and write to that folder)?
Public Sub GrantAllAccess(ByVal Folder As String)
Try
Dim DomainUser As String = Environment.UserDomainName & "" & Environment.UserName

I understand all about giving Administrative Rights via the manifest. However...I'm sure I will have customers that may not want users to have Admin privileges. Is there a way I can grant rights to just the folder where I am writing data to(database and pdf files). The folder will be in Program Files/my company/....

I have two tables Employees and CafeLogs. Some employees can be cashiers and also customers at the Cafe shop.
Table structures:
Employees: EmployeeId(PK) , FirstName, LastName
CafeLogs: LogId (PK), CashierId, EmployeeId, Value, => CashierId and EmployeeId are the data from column EmployeeId of Empoyee table
Table relationship:
Employees 1:N CafeLogs (CashierId (FK))
[code]....
Right now I know how to select only LogId, Employee's name, and , Value, not with Cashier name yet.
Dim query = From log In db.CafeLogs _
Join emp In db.Employees On emp.EmployeeId Equals log.EmployeeId _
Select log.LogId, emp.FirsName, emp.LastName, log.Value

I have 4 radio buttons, r1, r2, r3, r4. These four radio buttons are in a group box.
r1 and r2 for asking the gender of person.
r1 for Male , r2 for Female
r3 and r4 for asking whether the user would like to continue.
r3 for Yes , r4 for No.
When I click r1 , r3 becomes unchecked and vice versa. Similar is the case with r2 , r4. So at a time I can check only one radio button. How can I get around this problem . The groupbox is essential so I cannot remove it.

Using the following code
ControlCommand("Test Form", "", "[NAME:ctlMsgQueueCombo]", "ShowDropDown")
ControlSend("Test Form", "", "[NAME:ctlMsgQueueCombo]", "This is my default value (TEST) - First")
or
ControlCommand("Test Form", "", "[NAME:ctlMsgQueueCombo]", "ShowDropDown")
ControlSend("Test Form", "", "[NAME:ctlMsgQueueCombo]", "select", "This is my default value (TEST) - First")
It selects the combo box but not selecting the desired "this is my default value (TEST) - First" from the list. Basically what it is doing is selecting any value that starts with t . e.g first value is "TMP". So instead of exactly matching it is selecting any first character match.how to force it to select the exact string from list.Also tried using the following code but nothing seems to work
WinWaitActive($title)
$Index = _GUICtrlComboBoxEx_FindStringExact($hcombo, $sText)
_GUICtrlComboBoxEx_SetCurSel($hcombo, $Index)[code].....

I am not being able to retrieve from my access database in vb. Here is my code that points to the problem:
[Code]...
The problem I have here seems to me that the comparison between is crop_year =? where ? is the placeholder for Convert.ToInt32(cyrNote.SelectedItem.Trim) which is a value i get from a combobox cyrNote and try to convert it to an integer using Convert.ToInt32() so that it can be compared with the database value crop_year which is defined as integer in the database.
The problem here though is that the select returns null. I tried to replace the placeholder ? with a known value like "2011" and it returned a value. This means to me that my comparison crop_year=Convert.ToInt32(cyrNote.SelectedItem.Trim) is negative yet I expect something positive. I've tried to google on how to convert to integer and that is the best I could get.

I successfully connected a remote MySQL database and it is listed in the Data Connections. My database has two tables, inventory and history, both work and I can retrieve the data from each.The problem is when I try to link the inventory table to a datagridview object. As soon as I enter the configuration wizard a red x appears in my data connections. Regardless of this, however, I can still successfully add my history table. The problem is that the inventory table name isn't visible and I get this error:<``>Could not retrieve schema information for table or view ``.The inventory table is what I need and I don't understand why it blanks out.

I'm having trouble when trying to do a case-insensitive query on a table. Right now the query is:
txtQuery = "SELECT Status, RankingSearchEngines FROM [tbl-DATA-Client-Keywords] WHERE [Client-ID-Code] = '" & clientNo & "' AND lower(Keyword) LIKE '" & sField(0) & "';"
The actual query executed is:
SELECT Status, RankingSearchEngines FROM [tbl-DATA-Client-Keywords] WHERE [Client-ID-Code] = '1402' AND lower(Keyword) LIKE 'flyer printing';
I have an entry 'Flyer Printing' in the database, and this query works perfectly without the case-insensitive check.I'm not sure if this is an OleDB issue, as I've never had this sort of problem with SQLPlus, or anything else
The exception being thrown is:
IErrorInfo.GetDescription failed with E_FAIL(0x80004005).

I have a DataGridView table that I allow the user to enter data into. I have a button to add a row. This works OK but how can I select that row after the button has been clicked. The reason for this is so the user will not have to scroll to the bottom of the list the enter data into the new row.

I will post a sequence of examples and thought about sql injection, I wish the expert will correct any small mistake in what I will say so I can know exactly the possible danger.
The required is to create a function in vb.net that accept 2 parameter (table_name, fields_list) and return the result in datatable
Now, I am aware of that table_name and fields_list cannot be passed as parameter to the command object using .AddParameter
here is a couple of thoughts, what I would like to know is
1- which function is exposed to sql injection
2- Which function is more safe
Public Class Form14
Dim conn as New SqlClient.SqlConnection(connection_string)
Private Sub Button1_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
