• Visual Basic Passing things from Form1 to Form2 and back

  Hi everyone ! Imagine this : I have 2 Forms: Form1 and Form2 Form1 is the startupform and holds a button, Button1 , to show Form 2. Code: Dim F2 As New Form2 Private Sub Button1_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click F2.Show() End Sub On Button1_Click an new Form2 is shown. Form2 holds a button wich should change the text of Form1: Code: Dim F1 As Form1 Private Sub Button1_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click F1.Text = "hello" End Sub This gives the result : Object reference not set to an instance of an object.

• Visual Studio 2008 (Pre-release) databinding with a nullable value

  Hi, I'm trying to bind a property to a combo box wich in the initial state has a nullable value. When I do so, the databinding doesn't work anymore, if I select a value in the combo box it doesn't refresh the property. At first I thought it was my code, but if in the initial state of the property the value is not null, it works fine. Is there a property for the combo box that I forgot The following scenario seems to work fine, cb1 is bound to list of objects one of them being null. when I set cb1.SelectedValue = null. it selects null Item in the coombobox. when I enter something in the textbox, correct Item is selected in the combobox < ComboBox SelectedValuePath = " Id " Display ...Show All

• Visual Basic Null Reference Exception

  I am having a problem with a multi-form application I am writing in VB .Net 2003. When I transition back from one form to my startup form, I get an intermittent Null Reference Exception. Sometimes it will work, moving back and forth from form to form with no problems for 15-20 minutes, and sometimes it will crash everytime. I have tried putting a try-catch block around the instantiation of the main form. It does not catch anything. The exception points to line 2 of the startup form, which reads: Public Class frmWelcome Not much to cause a problem there, I would have thought. I am attaching the code for bringing up the welcome screen in hopes that someone will see something I am not thinking of. Try Dim welcome As New frm ...Show All

• SQL Server Navigation buttons

  Is there a way to add the navigation bar with next page, previous page etc buttons at the bottom of the report. If the report is long the users dont want to scoll up to click on next page. There is no easy way to accomplish this. It can not be done in Report Manager. If you are writing your own web app you could do this by writing your own tool bar, but it would require quite a bit of code. ...Show All

• Windows Forms "Foreign" msi files in a Setup project

  Hi there: Quick question: my application uses SMO, and I need to install that on the user's machine. I got the download from Microsoft in the form of a .msi file (the Microsoft SQL Server 2005 Management Objects Collection download from http://www.microsoft.com/downloads/details.aspx familyid=d09c1d60-a13c-4479-9b91-9e8b9d835cdc&displaylang=en ) . Is there any way for me to incorporate that msi file into my setup project I tried going through the prerequisites (I already have .Net 2.0 and Sql Server Express in there), but it is not dynamic enough to allow that. I could try and package the SMO assemblies one by one (the dlls were already added as dependencies), I'm just not sure how to force them to be installed in the correc ...Show All

• Software Development for Windows Vista Can DataExchange service hold variables?

  I would like to know whether "LocalCommunicationServices" could have a .NET property to hold data returned from within the workflow .This way the host can get hold of this property and tap the data out instead of using events where the same activity would raise a custom event and the host would recieve the data through the events arguements.(This is a long way of getting things done.....). The doubt is whether the information on this property is volatile especially when whe have our runtime hosted in a webservice and caters to many client calls. Thanks in advance.... There is not interface or abstract class to implement for a data exchange service, only the ExternalDataExchange att ...Show All

• SQL Server SQL Server 2005 Security:

  Hi I have a sitaution where I have domain admins logging on to SQL SErver and automatically accessing SQL Server as syadmin. Here are the steps I am planning to take to fix this problem! 1. Create a a non administrative domain account called SQLDBA and add it as sysadmin on SQL Server. 2. Make sure the SQL Services are using a special account called SQLServices non administrative domain account with Log on as service rights and added as a sysadmin on sql server. 3. Remove the builtin\administrators from sql server The way I envision this is anyone who log on with a domain admin acct will need to specially log on to sql server with a restrictive sql login instead of how they use to automatically get logged in. Are there an ...Show All

• Windows Forms Making a second non dialog form active

  Hi I have a main form which then creates and shows a second form. I want this second form to be the active form with the title bar highlighted. If I use ShowDialog to display the second form all is ok. However I want to show it non modally so use Show. However this shows the second form but does not then activate it The title bar of the first form stays highlighted. I tried using Activate but that suprisingly did not achieve it either. Steve Ahh yes, the good ole constructor. Rather than trying to do everything there (which you’ve already found can be tricky)... wait for one of the events that fires after Load such as Activated so that when Form1 is activated for the first time you are s ...Show All
