I have a sub in which I call different subs, depending on a value I pass through. It works fine for all but the last one. It executes the sub I call but then comes back to the first sub and runs the second one again

I am working with a datagridview and 2 text boxes.TextBox 1 is for entering time of the day and TextBox2 is for entering time duration in that order. After TextBox2 looses focus I am converting the times into index numbers in my DGV1 and filling the selected indexed rows with some data. The data then is checked and if there are issues message is display prompting the user to correct it. However, all my codes for checking the data and selecting options are in the DataGridView1 event handler:
Private Sub Datagridview1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles MouseUp
Is there a way to execute one Subroutine from another Sub. Sort of simulating a mouseup click programmatically ? Correction: there are 7 sets of those TextBoxes representing 7 days of the week. I am trying to avoid duplicating all that error handling codes in all 14 boxes. I have read that MouseEventArgs are protected so it may not be easy.

So, I want to execute a javascript on WebBrowser1 when I press a button. Normally, I'd just navigate to the javascript to execute it. Like this:
Private Sub WebPageEditorToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles WebPageEditorToolStripMenuItem.Click
WebBrowser1.Navigate("javascript:document.body.contentEditable='true'; document.designMode='on'; void 0")

This makes it where I can't leave the website and it keeps me on that one website. But the problem is that navigating to the javascript is not like [URL] so it won't let me execute javascripts that way. So, basically, my question is:
Is there any other way to execute a javascript with Visual Basic 2008 without navigating to it?

i seem to be having issues with my simple count down project. The count down work how I want it, there is also a pic of a rocket that move up when the count down button (Button4 - the form was set up in class as a quick example, so there was no need to name the buttons) is pressed. The problem is that the count down "10....1...Blast Off" shows after the rocket has moved up, I want the countdown text to show, then the rocket to move.The countdown is outputted to a ListBox.Here is my code thus far: (I have re-worked is a bit, starting to look messy)

View 1 RepliesI've created a program that creates a registry value when it is run, and when this program is uninstalled I need it to remove this registry value if it exists. So I wrote a little command line VB.NET program that simply checks for the reg value and removes it if it exists and I added this to the Uninstall section of the Custom Actions tab in the Visual Studio deployment project that I created for this app.
I know that the command line app works because if I run it myself manually it deletes the registry value, but when I uninstall my application it does not remove the registry value so obviously this command line app is not being executed.

I have published application before and they all (3 setup files) work fine. The problem is I don't know anymore how I exactly did it. Now I am trying to publish another form which has a connection to my sql database. The publishing goes fine: publishing folder is: C:Movie-databaseApplication 4 and installation folder is the same, and I therefore leave it empty. Application is available only online. But when I execute the published setup.exe I get two windows with no info about the error: see attachment.

View 2 RepliesI'm trying to eliminate a VB.NET button on my aspx page. Trying to use javascript and ajax to execute the same code my vb had.I put in a script manager, set EnablePageMethods to true, added a static subroutine, and referred to it in my javascript function (BTW -- this seems a lot of work just to execute an existing subroutine). The javascript calls my code-behind and it almost works.Problem is, now I'm getting a NullReferenceException when SimulatePrintBatchClick tries to do anything with the controls.
Error is 'Object reference not set to an instance of an object', line is 'pnlVars.Controls.Clear'
Here's the code from UW.aspx:

when I run the above code in PrintBatch_Click it all executes just fine. I really don't understand why it bombs out as a subroutine.
Perhaps this is not the way to do this, but I'm at a loss for finding a different way. Originally this code was handled by an ASP/VB button, but the specs have called for it to be deleted.
background worker is not executing all the code in side it. windows application..Although there is not any exception.
