View 14 RepliesVS 2008 - New Row / Cell Value Being Deleted In DGV On Error Trap
Oct 4, 2009How do I stop the new data row/cell value from being deleted if an error occurs. I am using the DATAERROR event to trap the error as shown below:
Private Sub RoomPricingDGV_DataError(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewDataErrorEventArgs) Handles RoomPricingDGV.DataError
e.Cancel = False
If e.ColumnIndex = 1 Or e.ColumnIndex = 2 Then
MsgBox("Invalid Date. Please Re-enter! ", MsgBoxStyle.Critical, "Room Pricing")
RoomPricingDGV.Columns(e.ColumnIndex).Selected = True
End If
e.ThrowException = False
End Sub
What I want to happen is to go to the cell automatically where the error has occurred and get the user to change it, not have to retype the whole data row or move back to the previous cell. When using the MSHFLEXGRID in VB6, it was fairly staightforward to do.

Aggregating Error Trap - Textbox That Is Used To Add Directories To A System Folder
Dec 16, 2009I have a textbox that is used to add directories to a system folder, each name seperated by a line. If the textbox has text value "Test " that is "Test" & controlchars.newline & "" (not like this is coded, it's typed in), then if i use loop for each part as string in textbox1.text.split(controlchars.newline), the first part will be "Test", the second part will say " " when i run step by step debugger, but if i try and block the addition of a folder by "if part = " "" it does not catch it. I've tried comparing part to "", " ", nothing (which is illogical anyways), and i even tried creating a boolean variable equal to the statment to try and catch it but the program insists that part is not " " even though the debugger tells me that is the value of part.

.net - Response.Redirect Does Nothing (ASP.NET) And EventValidation Returns Error If Enabled?
Mar 7, 2011I have a page in which one chooses from a selection of dynamically generated buttons. The ASPX code is as follows:
<div>
<asp:Repeater ID="rptrHalls" runat="server" OnItemCommand="Choose_Hall">
<ItemTemplate>
<asp:Button ID="btnChooseHall" runat="server"
[code]....
When I first tried running the code I received an error message of "Invalid postback/callback argument". I set the ASPX page to have a enableEventValidation="false" property and tried running it again. It generates the page fine but when I click on a dynamically generated button it acts as if it is loading something and then just brings me back to select_hall.aspx (the page all this code is one), when (as you can see above) it should take me to select_room.aspx.
Asp.net - Login.aspx And Catching The AD Error Authentication Response Value?
Dec 11, 2009I have used the code from the link below to create a basic login page in front of the Microsoft Live Single Sing On.[url] I managed to combine the two together(LiveSSO w/Forms Authentication) turning off the Integrated Authentication in IIS from the SSO setup.All works as expected if the user successfully authenticates with AD. THE PROBLEM that I am having is that when the user failes to authenticate it only returns: "Error authenticating user. Logon failure: unknown user name or bad password". This message appears also when the user is set to change the password at next logon. What I want it to do is to read the error code of exactly why it failed so I can setup a redirect to a password reset page (i.e. if error is "User flag is set to change pswd" etc.etc.)From the page linked above you can see the VB code of LdapAuthentication.vb which does the trick of authenticating the accounts or returning the error message if the login fails. The part that returns the "Error authenticating user. Logon failure: unknown user name or bad password." Is handled by this subroutine:
[code]...
That's what I have been trying to customize to see how it can return a specific code based on the user account AD flags, instead of the generic message

C# - Custom SNMP Trap Implementation In .Net?
Oct 2, 2009I need to create a monitoring mechanism using SNMP (in .Net). I think we'll be using an nsoftware component to handle most of the work. It appears we must use 'traps' to communicate from the agent to the server. We'll have a number of different traps and various information detailing each trap. What is the best way to implement custom traps? That is, what is the best way to not only send a trap, but also send the information describing the trap to our 'snmp manager'? I think this is done through "variable bindings". To use "variable bindings" do we need to create our own "enterprise number" and use an "enterpriseSpecific" trap? Should we implement our own, custom MIBs or can we just send the data we need with the trap (via variable bindings)?
