splash screen and flicker anyways

ns20-Jan-06 3:30

20-Jan-06 3:30

I have a splash screen with a timer. When the timer runs out, I show the mainform, which I loaded earlier in the form_load of the splash screen

Private Sub Form_Load()
    lblVersion.Caption = "Version " & App.Major & "." & App.Minor & "." & App.Revision
    lblProductName.Caption = "Work"
    tmrCountDown.Enabled = True

    'Set countdown timer to 5 seconds.
    timeInterval = 5
    Load MainForm

However when the app starts up I still see the flickering where the mainform is being loaded, alohng with the splash screen, even though it (the mainform) doesnt show until later.
How do I get rid of this annoying flicker?
thanks,
saroj

First, you don't make the Splash screen the start up form...

There are a bunch of examples on how to do this. You can find a pretty good explanation here[^].

Hi, you will have to make this a bit clearer. I dont have an answer, but in VB, you could log every key stroke, or you can have a timer and continually check which programs are running. depends what u want to log

Actually, I want a mechanism of reckognising which user is making which request in a multiuser enviroment so I can log events for each user. For instance, so many users can request the same page, I should be capable of logging the act of each one. Any further clearance no problem.

I had made an application in VB 6 in which i used Bar Code. I printed the barcode on the Employee Card. You dun have to do any thing there are fonts available throug which u can make bar code. e.g. if u have a report in which u want to have barcode just chage the font of the field the barcode will be displayed. and for reading barcode u dun have to code when bar code reader will read the bar code a text(against which bar code was generated) will be available where the cursor will be blinking. u can search bar code font on net these are free just install these and use

Web Service Client

Dear Ser

I need to create a web service client for the web service
[http://www.handigeproducten.nl/webservice/].

I tried to modify a large number of examples from different textbooks and internet sites. Not even one works!

Convinced as I am that it should not be difficult I have the brutality to ask you to provide me with a working example. A very simple example will do. For instance a simple application or html page on which the user provides an 'item number' and the page/application shows the results by sending information to the web service and showing that information on the html-page.

(We used to do this with a 'post', but this method is no longer supported by the web service)

< I am not developer but am trying to write the client >

Ours sincerely

Build your own example. Create a WebService with but a single method in it. All it does is return the number 1. This is as simple as it gets...

If you can't get a single example to work, what makes you think that anything anyone sends you will work either?

A WebService doesn't return an HTML page, unless it's written to do so. It's normal return is just some data like any other method you find in a class. It's up to your Web Forms ASP.NET code to do something to format the data and present the new page to the user.

There isn't much to this. It's best to have IIS installed on the machine you're developing this web service on. Preferrably installed BEFORE Visual Studio .NET was installed.

All you have to do is create a Web Service project, tell it the server and project name you want to use, then add code for your WebMethods to the class. Build the project, and a web browser will open to test it.

A quick example class looks something like this:

Imports System.Web.Services
 
<System.Web.Services.WebService(Namespace:="http://tempuri.org/WebServiceSandBox/Service1")>
Public Class WebServiceTest
    Inherits System.Web.Services.WebService
 
    <WebMethod()> _
    Public Function TestMethod() As Integer
        Dim r As New Random
        Return r.Next(Integer.MinValue, Integer.MaxValue)
    End Function
End Class

Common Error on dispose image

As my Question before,
I have search for "Invalid parameter used" on the google.

I found that many programmer also get this problem,
When some image dispose, like myPictureBox.image.dispose(),
It will always have the error "Invalid parameter used"
Any article for this issue?

Thank you!

Dave Kreskowiak20-Jan-06 2:03

No. I've never had the problem. It sounds like your missing a step in your code, like not setting the Image property to Nothing after your dispose the Image?

You can see this[^] for an example.

How To Check if update statement is executed successfully (qry.ExecuteScalar)

mayhem_rules19-Jan-06 18:49

19-Jan-06 18:49

Hi, I am using the following code to update records in an access table using vb.net.

Dim dr As OleDbDataReader
Dim qry As New OleDbCommand
Dim ucon As New OleDbConnection
Dim inssql As String

inssql = "Update PriceTable set Price = " & newprice & " where ID = '" & id1 & "' and Period = '" & Trim(period) & "'"
qry = New OleDbCommand(inssql, ucon)
dr = qry.ExecuteScalar

What I want to check is if the query has been executed correctly. i.e. if id1 (id1 matches with ID from PriceTable) exists in PriceTable, then it will be executed successfully. However, if the id1 is not present in PriceTable (id1 does not match with ID in PriceTable), then how do I know that the qry has not been executed.
Please provide assistance ASAP.

With Best Regards,

Mayur

shouldn't this be ExecuteNonQuery()...

This is the statement that does Update, Insert and Delete.

It returns the number of rows affected.

ExecuteNonQuery it returns no of rows effected by the query. use this:

Dim dr As OleDbDataReader<br />
Dim qry As New OleDbCommand<br />
Dim ucon As New OleDbConnection<br />
Dim inssql As String<br />
dim iNoofRows as interger<br />
<br />
inssql = "Update PriceTable set Price = " & newprice & " where ID = '" & id1 & "' and Period = '" & Trim(period) & "'"<br />
qry = New OleDbCommand(inssql, ucon)<br />
<br />
iNoofRows = qry.ExecuteNonQuery  'Instead of qry.ExecuteScalar<br />
<br />
