I'm not receiving any type of error, it's just that when a textbox is blank the error provider is not doing anything.
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.

My code editing program, with text colouring and lots more, is almost finished. It uses a rich text box to edit in.On the right is a listbox, called the "suggestion box" The suggestion listbox is kinda large and eats up lots of valuable edit space How can I display my "suggestion listbox" control underneath the caret, like in Visual Basic?
View 7 RepliesMy program in VB.net has been using in 4 years already. I coded it in my computer and run in other computer. It's modified several times and it still woked fine. Today, I modified it again. It works well in my computer, but when I run it in other computers, I got an error:
" Failed to decrypt using provider 'RsaProtedtedConfigurationProvider'. Error messsage from the provider: Bad Data."
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 know it's possible in asp.net to create a custom error page in a web app, by putting the following line in the web.config: <customErrors mode="RemoteOnly" defaultRedirect="frmErrorPage.aspx" />
I have had to do this for my web app, since it is clearly much tidier than letting the program bomb out with it's ugly default error page. My custom error page just has the customer's logo and a brief message saying "Error has occurred. Please return to homepage"The trouble now is that I have no way of knowing what caused the error, when a customer reports it.
Is there a way to make the actual error message appear on this custom error page too?

My first project was a small windows form application that I'm hoping to put on the office server and have it accessible to more than one person at a time. I wrote the code in Visual Studio, and put the exe file and access database on the office server. When another computer (that doesn't have visual studio installed) opens the file this error comes up: The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine. I realize I may need a quick download on these other computers to be able to read the VB program?
