Refreshing Form During Powerpoint Auto-mation VB 2008?
Feb 3, 2009
I have a VB 2008 Forms application which does Powerpoint automation -- I am opening owerpoint in a minimized window from within my app and am trying to periodically put update messages in a textbox on my main form while the automation is running (it takes a few minutes to complete), but my form window does not want to show these messages until the powerpoint operations are finished. It seems as if I need to force a window refresh or something on my windows form, but I'm unclear how to do that. Below is some code that I'm using that illustrates what I'm trying to do. When I run it, "Step One / Step Two / Step Three" do not show up on my textbox until after the Powerpoint automations are over.

The software company I work for offers data conversion as a service for new clients who have previously used other similar software. I've written a VB.NET application to automate common conversion operations, and have separate logic between known vendors.particular file layout has become rather common, but due to the nature of how this particular competitor's application stores information, certain fields mean one thing for one client, and another for a different client.Certain elements within this vendor's format change every time, so I've written the application to account for that. Because some data fields mean different things to different vendors, I have to change my mapping code every time. This wasn't an issue when I had one of these every six months or so, but these are becoming much more common and I would much rather find a way to further automate this process.

How do we automate the process of deriving an Interface from our already-designed class?In other words, I wrote in completion my entire class and now desire to automatically construct its interface. EG: Say my class's filename is "Car.vb", I now desire "ICar.vb" derived from the class "Car" that I've written.

I'm writing VB code in Visual Basic 2008 Express and can't seem to figure out how to create a new instance of Excel with VB code. The most common answer appears to be setting an object variable to 'Excel.Application', but that gives an error (Type 'Excel.Application' is not defined).

how to set a powerpoint presentation as the powerpoint.application.activepresentation? In the program below, when the form is loading, it will open 2 powerpoint files (Test1.ppt and Test2.ppt). After Test2.ppt is opened, it will be the activepresentation because it is opened last.What I am trying to do is when I press button1, it will set Test1.ppt as activepresentation so that when I press button4, it will show me "C:Test1.ppt".The same also goes to button2 making Test2.ppt as activepresentation..But what I get is, no matter how many times i press button1, Test2.ppt is always the activepresentation.[code]

I'm trying to copy a Range from Excel and Paste the information in powerpoint in either the HTML or the default format, however, I am having some difficulties. I am able to get the code to work for pasting the Range as an OLE Object but nothing else. The problem with doing this is that having the embedded excel documents in the powerpoint makes the file extremely large and unstable. I just need to be able to paste the information without the embedded information where it is editable (so, not as a bitmap or picture).
With ppt2Slide
Sheets(index2).Activate
Range("CP12:CT" & RangeIndex2).Copy

Basically I have two forms - Form1 has a DataGrid on it (Infragistics) and in the double-click row event it creates an instance of the EditForm and passes along the UniqueId for editing. Once the user saves the changes (if they make changes) - I want the DataGrid on Form1 to refresh. Here is how I thought I could get this to work ... I create a public property called RefreshRequired as boolean. Before unloading the EditForm it sets this property to true. Then Unloads. This continues the code in Form1 (which showed the EditForm as modal) but RefreshRequired is still showing as False? Why isn't my EditForm able to set the property?
FORM 1
Private Sub grdList_DoubleClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles grdList.DoubleClick

I had issues in refreshing a form that is bound to different tables in a database. Various forms allow the user to change and add and update information on the form via the database. I had created a public sub in that form that the other forms could call, after saving the data, that was supposed to refresh the data on the main form. This was not working so I researched the problem. I came across this page which pertains to Form.Activated: [url]
I placed all of the table adapter fills into this event, instead of in Form_Load, and it seems to work now, when the form first loads, and when other forms update data. My question is does anyone have experience using this and what are the consequences, if any, in using this to reload/refresh the data showing on the form?

I am working on supplier maintenance file. From mainmenu, opening first form shows records on datagridview through databinding. Clicking add new record, i fired a second form as my data entry with detail view through databinding, minus navigational buttons. I left the delete and save button only. Once through data entry, i save it on server. My problem is, how can i reflect the added record on the first form while i am on my second form? I prefer the new record be added only to the first form. I don't want the idea of retrieving the records again from my server.

I am trying to refresh a datagridview from a second form to display newly written data. I have read the posts on this topic and can't figure mine out. My first form opens and you input data into text fields, etc. and then you need to select items from one table to copy and write to a new table. The datgridview on the first form shows the new table, and I have a new form that pops up to select the line items to add. Everything works perfectly except when I close the selection form after selecting lines, I would like the datgridview on the first form to refresh to show that the lines have been selected and displayed in the datagrid.
My data is loaded into the datagridview as so;
Public
Sub ShowVoucherLines()

I've been working on this game the past few days, a simple game where two people control different tanks, and shoot each other, very basic so far.The problem I have is when one player is dead. I have the form recognizing each players death by using this code (It's within a timer subroutine)
'Player One Dead
If intPlayerOneHealth <= 0 Then
btnReplay.Visible = True
End If
[code]....
and that code is replicated for every key pressed (Arrow keys, WASD, e, and end). Those booleans are handled in a timer subroutine, where if the boolean is true, they will move/shoot. (Turning the booleans to false is done in the 'Private Sub KeysUp' subroutine)
TL;DR How do I get the game to restart itself when a player dies and hits the replay button?
P.S. I've tried 'Me.Refresh()' as well, and that didn't do anything
