Asp.net - Error Message When Modal Is Empty
Sep 22, 2011
I have a couple of modal popups on my page that hold checkboxes. The checkboxes are different items that can be added to a specific product. Some products, however, have all of one type of item assigned to them. I need a way to show a message in the modal when the modal is empty.
I have tried using a Label inside the modal that says "All features are currently associated with this product." But the label leaves a space in the modal when it's visibility is set to hidden and that was annoying so I ditched that idea.
What is a good way to have a hidden message that shows up when the modal is empty?
<asp:LinkButton ID="FeatureButton" runat="server">Feature</asp:LinkButton>
<asp:Panel ID="FeaturePanel" runat="server" CssClass="modalPopup"
Style="display:none">

Sometimes the app is working in a long time process, and I wnat to tell the user something like "Wait a moment, please"
I though to use a modal form but if I show this form, the process I said is not initiated.
How can I give this kind of messages?

I have a program that is using API's to send mouse events and keyboard events to another application that is running. I need to know how to tell if there are any messages left to process for that window after I have click on a button or moved to the next field. I need to know this so I don't send any more mouse or keyboard events until it has finishing processing everything in its message queue. An example is that I click out of the key field and the form has to go out and read a client record. This may take a second or two, so I need to wait until the form is ready for more input.

I've got a grid view. I want it to say "you have nothing to show" if there are no details.
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If GridView1.Rows.Count = 0 Then
[Code].....
However; it seems to be working backwards and showing the message when there is data to display in the gird view and continues to be a blank page when there is not data to display in the grid view.
I've tried a variety of combinations with the below IF statement below but no success.

I'm having an issue with the startup of my build app with vb2010.Let me explain what the situation is at the moment.
I have a form and a splashscreen. I use the application events (startup event) to check if there is a network connection, if so the splashscreen will run and it will check if the database is available, if this is the case, it will copy the online database to the local ms access database.If the startup check of the network is false, it the user gets a message that there isn't any network available and the program will try to run normal, then when the user clicks the ok button of that message, it will check if the local database has any records. If so the splashscreen will run and the program starts normal (without copy the database, because there isn't any network available).The issue that I am having is, that when there isn't a network connection and the local database is empty, (I do get the message that the local database is empty), but the program still runs, while it should exit.Here is the code of the application event:
Protected Overrides Function OnInitialize(commandLineArgs As System.Collections.ObjectModel.ReadOnlyCollection(Of String)) As Boolean
Me.MinimumSplashScreenDisplayTime = 5000[code]......

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?

At run time my application gives an error of "Conversion from type "DBNull" to type "String" is not valid. In my form only one field - Add_info is an optional field which might be filled or not by the user. Before, I had an error when an apostrophe was used so i updated the code as highlighted below. This in return removed the apostrophe error but generated an error whenever there is an empty additional field.
For irow = 0 To QryColSentDataGridView.Rows.Count - 1
If QryColSentDataGridView.Rows(irow).Cells(3).Value = True Then
Try
query = "UPDATE gprdsql.TblCollections SET system_time = '" & _
Labeldate.Text & "' where prac_no ='" & _

I have a database with lots of fields, some of which are still empty and are to be filled in at a later stage. Is there any way of writing an IF statement (or any other method) that will allow these empty records to be 'shown' in my textboxes in Visual Studio, without receiving the error:
Conversion from type 'DBNull' to type 'String' is not valid.

I'm using visual basic to code a program to help with weights and center of balance on aircrafts, as I'm my unit's new air load planner. The math isn't hard to do, it's just that much of it is trial and error, and redoing all the arithmetic over and over again until the aircraft's C/B is in acceptable limits can eat some time up. So, since i'm trying to learn programming I thought this might be a good way to use it for a real-world scenario.

This May sound strange but I have about 10 Visual Basic book, including two references that don't explain this property. It is mentioned but there are not examples as to how to use it.
I just came across this property MaskCompleted but I am not sure how to apply it so that MaskedTextBoxes are not left empty or a message is generated.
