• Visual Basic It's slow!!!

  Hello After I turn on my computer and when I launch first program (which programed by VB2005), it's take a long time to show main form. VB6 was faster.   CPU speed: 2600 MHz Memory: 1024 MB  Is there a solution for that   Thanks & Regards What do you mean by 'long time' It's possible that, even though windows appears to have finished booting up, it hasn't - it's still loading and starting various services (e.g.SQLServer). Additionally, it may be that the .NET framework needs to load prior to your application loading. Did you try using a splash screen to see if t ...Show All

• Visual Basic Declare and Call A Fortran DLL from VB 2005

• Windows Forms Internet zone

  Hi, I have problems with applications deployed using ClickOnce from the Internet zone. I have created a sample application (just a form with a button that makes an illegal operation in this zone - looks if a file exists). http://www.valil.com/TestExpress/TestExpress.zip I have set the zone to Internet and I have deployed it on the web server. When I try to run it, I get the message "Application has been blocked ..." (the message you get when you try to run a full trust application). I must mention that my website has the problem from this thread ("Problems with MIME settings at the hosting provider") so the deployment manifest has the ext ...Show All

• Visual Basic DataGrid Check Box Cell CheckState

  I am trying to use the CheckBox Cell in a Datagrid View in 2005. The problem is I a am having trouble determining wether the cell is checked is not. My plan is to allow the user to check / uncheck the rows and then loop through them and update the SQL backend accordingly. But i can seem to find a way to check wether the cell is checked or not. At the moment I update the database on the Cell Click event and do a check on a field in the dataset to the inverse of what is there i.e. If the check box is ticked check the Value of the cell in the Row and reverse it. this is for a simple Y / N Field  and then refill the data grid this is a bi ...Show All

  I am wondering if it is possible to replicate n number of state machine workflows from within the state initialization activity.  Thanks I don't think that solution would work, as the activity would be an InvokeWorkflow, not the child state machine workflow.  From within the workflow, you can use 'this.WorkflowInstanceId' or from an InvokedWorkflow, you can use 'invokedWorkflowActivity.InstanceId'.
