Currently Im doing research on something that are related to graphical password.Can I know is that possible ASP.net(vb) can do such things.when mouse hover over a image, that image id will automatically save in database?Lets say that there are multiples images display in GridView. Only 2 images is the answer. So when user use mouse hover on those images, those images id that mouse hover will saved in database. Then, system will check 2 images id is in the list that mouse hover just now or not.

I am working on a school project to display a photo of a professor when their name is selected using a RadioButton and to display their name, office office hours and so on.
I have their Photos in a directory on my computer
Theonly thing I cannot figure out is how to use 1 picturebox and link the image to display to the radiobutton.
I have tried all kinds of queries on the internet and cannot locate the answer. There might be something with an Image.FromFile command I saw but that might have been from a previous version of VB and I could not get it to work in VB9.

When I run the code, type a value in quantity and hit the calculate button I get an error message stating, "Quantity must be a numeric value" and I don't see in the code what I have missed. I thought I set quantity as a numeric value by making it an integer and parsing it.
Private Sub calculateButton_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles calculateButton.Click

I created a DataGridView called grid_LivingBenefits.Each time a cell is going to be edited, the program will validate that cell.Now, I have two subroutines that take care of that validation.these are: ValidateDataType() and ValidatePrimaryKey()
at the DataGridView CellBeginEdit, the program checks for which cell the user is editing.at the DatagridView CellEndEdit, the program calls the subroutines for validation. If an input is invalid, I want the program to show an errorProvider on that cell.I used MessageBoxes first to check whether the validations are working and I got no problem there. but when I tried to use errorprovider instead of a messagebox, there's a blue zigzag line under the grid_LivingBenefits.CurrentCell

My app fails at this line of code:
Dim objConnection As New SqlConnection(Application("ConnString"))
My connection string is: [Code]. I googled this problem and the solution for it was having a malformed connection string where the "provider" was being specified when it shouldn't have. Example conn string: [Code]. I'm not specifying the Provider so I think I have a different problem.

First attempt at using the error provider, I've set this up for each of the five text boxes I have on my form, when I click the button it shows the error provider flashing between the various boxes if I leave them all empty. Ideally I'd like the form to show the symbol next to the box thats empty, click the button and remove it from those which are correct leaving only the incorrect text boxes with the symbols. Any thoughts? [Code]

I'm trying to set up a database connection between an ASP page running VBScript, and I have found code to do this. However, the 'provider' attribute to the connection does not work. The code is below:
set conn=Server.CreateObject("ADODB.Connection")
<strong>conn.Provider</strong>="Microsoft.Jet.OLEDB.4.0"
conn.Open(Server.MapPath("mIndexDb.xls"))
set rs = Server.CreateObject("ADODB.recordset")
rs.Open "Select * From mIndexDbTable", conn

I requested a Code Signing Certificate from my own domain Certification Authority on my Windows 2008 R2 domain controller.
When trying to publish my code to my webserver via Clickonce, it throws "an error occurred while signing: Invalid provider type specified"
In order to get the certificate I duplicated the Code Signing template on my CA, and tried both options available:
1) must use Microsoft Software Key Storage Provider
2) use any provider available locally
algorithm is RSA, key minim size 2048, Hash SHA1, alternative format unchecked

I'm working on my first VB.NET 2.0 WinForm app. I'm trying to validate some input and I came across this fancy Error Provider control that seems great. However I have a problem with it. It seems that it only validates a field when it loses focus. I'm used to Web Form programming and using validation controls on it, but I don't see these in WinForms.

I am writing a User Control. Into each control I am loading a custom biz object. Because the biz object implements IDataErrorInfo interface I am able to use the ErrorProvider control on the user control.
I am binding the ErrorProvider to the biz object like this:
Me.ErrorProvider1.DataSource=MyBizObject This is all working perfectly EXCEPT. The validation is happening (and therefore I am displaying the blinkey error signs next to all feilds) as soon as the User control is loaded into the host form.
Each biz object implements a SAVE method and I want the validate to not happen until the save event is triggered on the biz object.
