I need to create an app in which different users will change data from a DataGridView. I was thinking to use SqlDependencies to automatically update changes.
I have tried the example from link bellow but it seems that something is not working properly.

View 1 RepliesI have an asp.net web app that uses forms-based authentication, a SqlMembershipProvider (using an encrypted password format), and a SqlRoleProvider. I need to know if it's possible to administer the users (create new users, assign them to roles, etc.) from a windows application - the powers that be don't want any administrative functionality in the web app itself.Here is the membership provider definition from web.config:
<membership defaultProvider="MyProvider">
<providers>
<add name="MyProvider"

View 1 RepliesI've designed my own encryption application in VB 2008 that has a free tools section where users can choose a particular wizard to use from the drop down. The javascript wizards display the code required to put in their own sites. I already created wizards that users can well, use.I see people have their own "contact form wizards" on their websites all the time. Where users can use the wizard and get the displayed code to copy and paste on their sites. But trying to locate source codes to these things is very aggravating on the web.So what I want to do is create my own "form wizard" like out of javascript, that allows the user to put in some information then get the displayed code to put in their own websites. I'm not looking for the generator such as the online form generators.But the javascript source code(s) for the generator itself.Then I could simply put a form generator inside of my VB-app, that will allow the user to use the wizard, then get the html code to paste in their own sites. Preferably not the PHP one because the php backend is very difficult to put in a VB app.I know that it can be done. For example copying a web pages source code then putting it inside a string, then calling that string from a button click that will open the javascript page in the webbrowser inside the VB app.
View 2 RepliesIt seems like when there is only one row at the data grid view with a data source pointing to a data table, it's row state for the data table doesn't change when editing. It remained "unchanged" reguardless to how many columns I had entered. However,after editing, when you click on a different row or click on any of the column headers to change their sorting, the row's state from the data table then gets changed to "modified". I'm not sure why the data table's row states gets changed only when you do those things instead of finishing editing itself. Couldn't the data grid view be able to change the data table's row states when you finished editing a cell?

View 1 RepliesI was wondering how I would take a SQL statement and reuse it for all users in the database. I have the code for writing to one but it contains information regarding the user so is there a way I can add all of the users to an array from the database. If so what method is used to get all of them into that array, if possible?

I'm writing a program in vb.net that automatically creates users from a database.It works fine, as long as there is no comma or there are no two spaces in the CN.
I am using the WinNT interface, so in fact it creates a SamAccountName and copies it automatically to the CN.When I create the entry manually in AD, I can add comma's and spaces without problems, so it should be a programming error.

I created a piece of code to create users in our active directory (2003) Everything is working OK and all attributes are set correctly. Only if i logon with a created user i do not get the mapping H: to the homedrive. When looking in ADUC the path to the homedir is correct. Also permissions on the homedir are correct and the user is owner of the dir.
If i correct the path in ADUC to another path and change it back again to point to the homedir the drive mapping is made correctly, so it look's like some kind of attribute is not set correctly. I used ldp.exe to view the created user's attributes before and after modifying the path but don't see any difference.
Tried to create the dir before and after user creation but that's not making any difference.

I have a DataGridview. The user has to pick an option in the datagridview. I am contemplating either putting a context menu in the DGV. I am assuming that I will fire my context menu on the Cell Enter event. However prior to that I need to draw the users attention to the column of interest.
I know I can hide all other columns but his is not userful as they need to be visible. I am also assuming that I can highlight the column in the form load event. Or I could use some sort of Call Out box in the form load event that draws the user to the column. Can you create a call out box from a context menu?
I am trying to use dataview.Rowfilter to filter datagridview for users. The basic idea is that user enters a text in a textbox, and then the below function is called to filter the text in all columns, like Col1=value OR col2=value OR col3=value. But I got error message of the filter expression.

I'm wanting to create a control that allows users to upload PDF files and PDF files only. I know that there are object properties for windows forms that allow certain file types, is there anything for win apps? Or do you just have to check the end file extension after they tried to upload it and display an error? I've never done anything with web app uploading before.

I am trying to create a small form that will duplicate a users entry for them.On my form i have a text box and two CheckListBox controls and a button. The user should be able enter a value into the text box, and select multiple items from both CheckedListBoxes, when they click the submit button the details will be added to a DataGridView below.
This is an example,The user enters the value Audi A4 into the textbox.
The First Checked Lsit Box is called "Colour" and from the options the user checks 'Red' and 'Blue'.
The second Checked List Box is called "Number of Doors" and from the options the user checks '3' and '5'.
When the User clicks the submit button 4 rows will be added to the DataGridView with all the different combinations, as shown below:
Model Colour No# of Doors
Audi A4 Red 3
Audi A4 Red 5
Audi A4 Blue 3
Audi A4 Blue 5
I am currently using this to populate the DataGridView:

My applicaiton makes use of the Event Log to log exceptions and Informational messages, however when logged in as a Standard User who has limited access, I am receiving the Exception[code]...
I understand that the Event Source cannot be found in the log I am writting to (Application) and the application is attempting to create the Event Source but before it can be registered all Logs need to be reviewed to make sure the Event Source isn't already in use.
My question is how should I go about creating an Event Source that can be used by Standard Users? The application will be operating on a corporate network whereby we lock down all users to the least required privellages.[code]...
I am trying to write a protection procedure, which will allow me to create a licence key for our users. This licence key will ensure that the software can only run on the registered system, and will allow the user to access only specific areas of my program which is relevant to them.
I am thinking of using an RSA style approach to this where I want to be the only person who can create the registration keys. But I want to allow the program to be be able to decrypt the key. This is to prevent the average user from being able alter the key and remove any restrictions which are being imposed on the program by the license key.
The process that this would take is to produce a host id which has went through a series of tasks to distort the actual value from the user will return this code us, and from this host id I can then work out the original value of the code. Using these public and private keys I can then encrypt license key information.
However I would like to know how I would implement the private key encryption and key generation program in .NET, so that I can get this setup working in a manner which will allow me to generate keys and allow the program to decrypt keys.
I Fill a DataTable using a SQLDataAdapter then use a BindingSource as my DataGridViews DataSource. My DataGridView contains a ComboBoxColumn named "Status". There are two ways to update the Status column. One, the user can change the value by clicking a cell in the column then the combobox appears and they make their selection. Second, the user can click a button on the form and the Status for all the visible rows are changed to "Exported". I use a stored procedure as my adapters Update command.
