IDE :: Creating Data Entry System For Local Community Group?
May 14, 2011
I am trying to create a data entry system for a local community group. I am working with VB.NET 2010 and MSAcess 2000. I am completely new to using a DB in VB.Net. I have created a form with the membership table bound as details on the form and the classes they are attending as a DataGridView. I used all the Visual Studio GUI tools for this. It was reasonably straightforward once I got the hang of things. My problems arise when I try to ensure that a user cannot move to a new record or create a new member without first saving any changes they have made.
I am using ColumnChanging events in the ...DataSet.vb class to set flags to indicate whether any data values have been changed on the form. My problem is that the ColumnChanging events for the classes DGV fire immediately on changing the data whereas the ones for the member details don't fire until I start to move to a new record. I don't know if it is important but my member navigation is achieved by means of a combobox on the form that lists the member names from the table. I have absolutely no idea why this works - it just did; the form updates as soon as the user selects a new member in the combo box.

The following steps give a Guest shutdown policy.
1- Click run, and type the gpedit.msc, to start "Local Group Policy Editor".
2 -Expand "Computer Configuration" -> "Windows Settings" -> "Security Settings" -> "Local Policies" -> Then click "User Rights Assignment".
3- In the Policy window, Select "Force shutdown from a remote system", double click it, it will pop a properties window.
4- Click "Add user or group button", add a user and name it Guest.
I need to know if it's possible to manipulate and add the user or group programmatically. I'm using Visual Basic 2008.

I am using System.DirectoryServices.AccountManagement to try to add a local account to the local administrators group with the following code but am getting the error below on the group.Members.Add(usr) line. Both usr and group are created as objects and if I create a Test group, I can add the user to the Test group. I know the group object is the local administrators group and not the domain group because i changed the description on the local administratrors group and the group object is correct so it appears to be something specific to the local administrators group.

Does anyone know how this can be done? The problem is that when you run the script to add a domain user to the local group as a local user you have no permissions to query the domain. Is there a way to pass a user name and password when doing this? [code]...

I need to have 4 text boxes and three command buttons. One button should be used for exiting the program, one button should be used for clearing all of the text boxes, and the last button should be used for any calculations/conversions. You should also have a radio button group for the user to choose entry temperature type.
One text box should be used for the entry of an initial temperature. The radio button group will then allow the user to select the entry temperature. When the button is clicked for conversion, the other three text boxes will populate with answers to the conversion. and if I enter 37 degrees Fahrenheit, the Fahrenheit text box should read 37 after the conversion.)

to add a windows user.The problem is i need to add the user to a group, but the groupnames are localized.E.g. the MS-example uses an english computer, which means you can get the guest group like this:
grp = AD.Children.Find("Guests", "group")
But on a non-english computer, the 'Guest' groupname is localized, meaning for example on my german language OS, the group name for Guests is "Gäste".Which means for the support example to run on my computer i need to change that line to
grp = AD.Children.Find("Gäste", "group")then it works.Now if the OS is any other language, how can I find the name for the guest user ?Or how can i get the guest user name from a sid ?

I want to be able to get and set values of Local Policy Editor using vb scripts (or for that matter any other command line thing). The problem is that for my requirement I cannot rely on the machine in question having anything like powershell. I want to be able to run a script/command and get/set the values of things inside Local Group Policy Editor.
eg. I want to be able to set things like running gpedit.msc and set the value for "\Computer ConfigurationAdministrative TemplatesNetworkOffline FilesDefault Cache Size", and I want to do this without manual intervention.

I'm in the process of writing a script for use in our lab. I need it to remotely add a domain user to the local group "Remote Desktop Users" on some remote desktop servers we use to bridge two subnets. The person adding the user would have admin rights for that remote server. I would use GPO, but we don't control the domain and it'd be damned near impossible to convince IT to set aside a OU for us with just those machines. I've been looking at using WMI in the script I've been working on but I haven't got the slightest clue how I'd implement it.

How can you add a system DSN with its security credentials programmatically at runtime from VB.NET? Keeping key in ODBC.INI is done, but when creating ODBC, it asks for Authentication Type (SQL or Network Login).How can we set that option at runtime?

I've built a couple of Apps successfully, but having published them to a Network Folder, Non-Admin Users can't install them themselves because the Install attempts to create an Entry in the Start Menu. There may be other Security issues (I need 4 of the permissions included if I publish it as a Partial Trust Applications, which I think affect this) after this point that I'm not aware of, but yeah, it fails when trying to create a Start Menu item -
+ Access to the path 'C:Documents and SettingsJameOStart MenuProgramsMynas' is denied.
I think excluding the right is just part of the SOE, but is there some way I can create this and have it NOT create a Start Menu item, haven't been able to find any?

So I came across this code that enables a drop shadow on a form in Visual Studio .NET 2008. The code is as follows:

Int32 = &H20000

I want to create a drop shadow on a group box though. What changes can I make to this and where must I insert it to do this?

Currently we are using a VB script macro created in word to create some fairly simple forms based off of data entered on a data entry form. I am very new to VB, and I have been able to create many applications using forms, but I have absolutely no history creating reports. I have been reading up on the reports, and it looks like they are designed to use with data sources like tables. I merely want to take either data from the entry form, or from data derived internaly from processing the user entered data and populate a defined report "form". I have been searching, but there is so much on printing reports, that I feel overwhelmed. I am not looking for the exact answer as much as a link or place to look for a sample for what I want to do.

CODE:
That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)

I have an application that receives data input from an automated set of devices. This data stream I have managed to capture & get it into a list box which I can sort based on the Device ID & the time that the response was received.There is a set time window for the devices to transmit their data into the application and during this each device is not limited to the number of responses it can send (ie :- Device 1 can send in 2 responses where Device 3 can send in 40 responses, etc).All of the responses are captured, listed & sorted within the listbox (this bit is working ).I now need to extract the last (ie:- latest) entry in the listbox for each Device ID & this is where I am stuck. I can retrieve the last item in the list but cant seem to extract the last item for each Device ID.[code]

Basically, our users enter values onto a spreadsheet and I have been asked make the spreadsheet output to a CSV file preferably each one completed appears as a single line in the CSV.Upon examining the spreadsheet, I cannot figure out the best way of acheiving this, or if it is easily acheivable in the first place.I have attached an example of the spreadsheet data, to give it some context the spreadsheet records times that carers have visited a client, which can happen many times a day over many days per week, there is also a yes/no for each day on the sleepin.
