Refreshing Form During Powerpoint Automation
Dec 2, 2009
I have a VB 2008 Forms application which does Powerpoint automation.I am opening Powerpoint 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.[code]

I have a simple form, with a button that invokes some Powerpoint automation (I am using VB 2008; Office 2007 is installed on the machine). Powerpoint starts up properly, the presentation closes, but...Powerpoint stays "up" (does not quit). When my application eventually closes, powerpoint does close, but I would like for it to properly close right after the automation completes.
Code:
Imports Office = Microsoft.Office.Core
Imports Graph = Microsoft.Office.Interop.Graph

I have a commandbar model which automates PowerPoint. I recently faced a strange problem that when PowerPoint is opened through my application, and the data is being loaded through my application to populate the menu.If a user right clicks on PowerPoint I get the error message: Call was rejected by callee powerpoint
How do I resolve this? I'm using Office 2003/2007 and VB.NET for office automation.

I have been searching and trying for quite some time now but did not yet find the right way to solve my problem.Here is what I want to do:- open powerpoint with a file (an disable the UI of my app while it is opened)- make some changes to this file- save it with a new name- get notice when Powerpoint is closed (either by my app once the automatic changes are done or if the user quits Powerpoint)- enable UI once Powerpoint is closedThe notice is my problem. Is there an easy way (other than timers that check the process list) to get notice of when my started Powerpoint-Process is closed/quit?

Here's the user environment: Microsoft 2003 Web Server Microsoft Visual Studio.Net 2005 (VB.Net) Microsoft Office PowerPoint 2003 We are attempting to use Interop in a web service to update PowerPoint presentations. It worked great on my laptop, but when we migrated to the server, we encountered issues.Basically, it started taking 10 or more minutes to open up the presentation, which means we usually time out.

I have created an addin specifically for Microsoft PowerPoint 2003 that will cature any save attempts made by the end-user. The purpose is it analyse where the file is saved to and to take a copy of the saved file for version control.I have created a module level object mobjPPT which contains my PowerPoint application object and have assigned the PresentationBeforeSave event to my sub 'PowerPointSave'. Everything works up until the point it hits the 'Pres.SaveAs' line and throws the following error:
System.Runtime.InteropServices.COMException (0x80004005): Presentation (unknown member) : Failed.
at Microsoft.Office.Interop.PowerPoint.PresentationClass.SaveAs(String FileName, PpSaveAsFileType FileFormat, MsoTriState EmbedTrueTypeFonts)
at PPTSave.Connect.PowerPointSave(Presentation Pres, Boolean& Cancel)
I have tried calling SaveAs on the mobjPPT object instead but get the same results.Here is the offending item:
Code:
Private Sub PowerPointSave(ByVal Pres As Presentation, ByRef Cancel As Boolean)
Dim dlgResult As DialogResult = Nothing
Dim dlgFilter As Microsoft.Office.Core.FileDialogFilters = Nothing

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

I have an mdi child form called "MyChild".
I need to refresh this form by calling the "MyRefresh()" method if the form has focus, and no controls have been clicked on in this form for the last 60 seconds.
Is there an efficient way of doing this ?
In the activate event of the form I could set up a timer and give it an interval of 60 seconds but what about checking for user intervention at any point in that 60 seconds ?

I have a databound combobox that displays a list of items, and I have a windows form that opens after clicking a button that allows me to make changes to the table that the combobox gets it's values from. When I make the changes and save them (successfully) and return to the parent window, the changes aren't reflected in the combobox. If I exit the app and launch it again the changes are reflected perfectly. I've tried me.combobox.refresh() on the forms GotFocus event, but no luck.

so I am a little confused. I am trying to refresh my datagrid when I have either add, deleted or edit a row via another form. I have it so my main form shows the datagridview, I have bound my controls to the database and I see all rows, no problem. I also have it setup to double click a row and it brings it up in another form to edit that record. This works. but it doesn't refresh the datagrid when saved. I am trying to follow this thread, specifically this post Refresh Datagridview - Post 2 Here is how I am loading the datagridview in main form
