Create A Form That Managing The Access Level Of User Management System?
Oct 7, 2008
I try to create a form that managing the access level of user management system.The model I use is the following :I create a connection to database I create a DataAdapter to transfer the data from the database I create a Dataset to hold my data My form consists of the following :A ListBox that list all the access level namesThree text boxes: the first for the record ID The second for the access level name And the third for the discription of the access level Five check boxes:One for writing rights One for the deleting rights One for the Updating rights One for Printing rights And one for Special area access rightsSo what i do is the following :I create a connection string I create a new connection to my database server I create the DataAdapter I initializing the DataAdapter command such as SelectCommand, DeleteCommand, e.t.c.I fill my DataSet with the data DataAdapter get from DataBase I binding my controls to DataSet I setting the DataSource property of the ListBox to my DataSet I setting the DisplayMember to the ACCL_NAME column of the DataTable inside the DataSet I setting the ValueMember to ACCL_ID column of the DataTable inside the DataSetUntil this time all are fine ! ! !The question is :When i try to add a new row to dataset by using the following code i have a problem :
Dim newRow As DataRow = Dataset.Tables("TableName").NewRow newRow("COLUMN_NAME") = Binded Control Value DataSet.Tables("TableName").Rows.Add(newRow)
Basically I am trying to create a child management system for a nurse using vb.net and SQL as my backend dbThe application consists of a number of differen forms. Two of these forms are called "frmSearchInfo" and "frmChildDetails".
frmSearchInfo consists of: - three textboxes "SFirstName" "SLastName" and "SDOB" - one button "BtnSend"
[code].....
When users enter details on form "frmSearchInfo" I want it to be able to search records in the database and return the same first name, second name and DOB as well as the ID, phone, addressline1, addressline2, county. I also want the datagrid to show dates of appointments for the children.The records needed are stored in the Child Table.
i don't want to use the system date and time in my mini project.i want to create my own system date and time to be in sync with standard time i specify?
I have searched the web for code relating to changing the system volume, muting the system volume, and outputing the current level of the volume as an integer, using VB.NET.
All the code that I have found either doesn't work, or is very long.
We are thinking about changing our current database system, MS Access 2007 front end and MS SQL Server 2005 backend to using a higher level language such as Visual Basic .Net. I wonder if this is the BEST solution for data management? Currently, among others, we have two big database programs that handle more than two hundred users and it's crashed often. That's the reason we think about changing to something that can handle these database programs effectively preferably using MS technology such as .Net.
I want to create a log in that allow the user to select different level of access when there using the program. Ok here is how I want it to be the user must select either user or admin, along with typing in there password and username, but I'm a bit confuse in putting the coding together.
I'm writing a form that get some informations from a database to manage the User Access Level.The way i do that is to Fill a Dataset by using a DataAdapter and the Bind some controls to the Dataset.The controls i binding are a ListBox, a Textbox, and five Checkboxes.All are fine with this controls. I can delete values and update values, i can choose a record from my ListBox and the values of this record to be desplayed on the othrer binded controls and so on.
I have a login page, which a user will have to enter username, password and accesslevel. Accesslevel is either 1 or 2. 1 for admin and 2 for users who are restricted from using certain functions. I have this module set up so that I can make use of the accesslevel throughout the forms that I have.
Module ModuleAccessLevel Public AccessLevel As Integer End Module
Arjun taught me how to make use of this module, so now I know how to restrict users from using certain buttons, toolstrips by doing the following:
I have a workable code below which checks the values you type in a textbox and compare it to database. If successfull, display "log in successfull"Now i want to have it redirect to a another form base on an "access" attribute in the database whcih i had already assign.
I'm developing a standslone system for my school project. I'm developing an audio management system which allow user to add audio files itself into database together with the audio information such as artist name and album year. I just started it few days ago and face some problems.. my song in the playlist wont continue to play after 1 finished and i need some idea on how to store the audio files into database ... in blob types may be?
Heres the screenshot and codes

I am creating an Excel add-in written in VB.NET. I would like to bind KeyDown and KeyUp events to the spreadsheet to record when the user presses and releases the arrow keys while navigating the spreadsheetIdeally, these events would be built into Excel alongside the native SheetActivate and SheetSelectionChange events, for example. Alas, they are not.
I thought I postet this yesterday but I can't find my thread so if this is a duplicate please point me at the original one. Background: I need to create a user account and Modify it's registry before the user logs on the first time. Creating the account is done by using the Winnt provider (works great). To create the profile I'm trying to use Process.start to launch a process as the newly created user. With the use of loaduserprofile property the users profile gets created and i can do my regwrites without problem.
I have a problem in adding/creating a new user to the system. The data entered didn't successfully inserted into database. It didn't show any errors too.

I am using VB Express 2008, and I'm experimenting with querying WMI. I have tried the code samples from MSDN, but they do not compile. Here is an example of code that my IDE doesn't like:
Imports System Imports System.Management Public Class Query_SelectQuery Public Overloads Shared Function _
[code]....
In this case, SelectQuery and ManagementObjectSearcher are underlined with squiggly blue, and it doesn't know what these are. What am I missing here? Please help, because I'd love to be able to write console apps that query WMI.
I'm trying to write some code that can read events from another computer's event log. I haven't used WMI or System.Management all that much before this, and despite all the examples I've found on the web (there's a lot), I cannot authenticate to another machine.
No matter how I tweak the code, I always receive a System.UnauthorizedAccessException in System.Management.dll. (The message is "Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))".) I have tried connecting to two different Vista machines on the network using their local user account information.[code]...
I want to learn by resolving a problem i have been having with my small car hire business.
I want to develop a system which will enable me manage the business efficiently, the solution should be able accessible to more than 1 users, on my LAN and i would also like to have a web reservation system.
How easy/difficult is this when using VB.Net and what things must i do at the onset to achieve my goal.
I am the beginner to .net framework itself.I am too confused whether to use asp.net using vb or just visual basic is enough?As I am just thinking over this topic.I feel this is not a website so not to go for asp.net.I thought to do it in
I'm trying to create a simple user tracking system so whoever has the program open can see who else has the program open. I know how to retrieve the username and everything. What I was doing was updating (loading and saving) a listbox with a text file on the network with the usernames in it. I can't get it to work right and I think its because the simultaneous opening and saving of the same text file by multiple users. I know this isn't technically the best way to go about doing this but it seemed like it should be the easiest. I don't want to make a huge project out of this because it isn't that important, it would just be nice.
As the beginner I want to know Is it necessary to add MDI parent for Library management System?
Can this be done without MDI Parent too?
And also is it necessary to add the below code for mdi parent of every project? Private Sub ShowNewForm(ByVal sender As Object, ByVal e As EventArgs) ' Create a new instance of the child form.
I've been assigned to do some report analysis in a management information system.My question is, do you think it's a efficient way to gather datas from SQL, with the use of basic syntax and have them manipulated through my code in VB.NET?(I'm more skilled with this kind of execution, but it takes a lot of data calling from the database)Or should I just do the advance way of inner jointing or more likely a stored procedure?
I ran accross this piece of code that uses the System.Management to get the free space on a drive for ONLY logical drives on Hard disks drives. It does this by check the Mediatype. Anybody know where I can find a listing of the Mediatype values? I would like to modify this to get free space only from USB flash drives.
I have read a ton of stuff about this but not getting it, noob error I am sure
Type 'System.Management.ManagementObject' is not defined. Type 'System.Management.ManagementObjectCollection' is not defined. Type 'System.Management.ManagementClass' is not defined.
I'm looking at creating an asset management system for all our electrical equipment, the equipment already have security labels with barcodes on them. What I am wanting is to be able to do is create a form where i can state some general information about the piece of equipment and then scan a barcode to register the equipments security number. so that if an employee needs to use that piece of equipment off site then I can just scan the barcode and register that the employee has taken the equipment.
My understanding is that the barcode reader is generally plug and play and acts as an input device? So what I would need to do is find a way to identify which input device is used, and if it is the reader find a way to assign a labels text to the value that has been read, rather that insert it into a textbox? I also want to display the actual barcode itself above the label, so I assume I would need to re-generate the barcode as an image and then display the image?
I have some software that does the following code to try to loop through the software (MSI's) that are installed on a machine. Originally it was passing in a package name as a parameter, but I've simplified my code to make it easier to follow. It was working before, I can't figure out why it's not now. Here's an example snippet with a package that doesn't exist:
