I use Imports statement for PowerPoint automation in my VB.NET application:
Imports PowerPoint = Microsoft.Office.Interop.PowerPoint
and of course, I have to check if PowerPoint is installed in the user's machine or not. However, because of this reference the application does not start or load to give me the chance to check if PowerPoint is installed or not. Here is the code I use to check in Form Loading
Dim officeType As Type = Type.GetTypeFromProgID("PowerPoint.Application")
If officeType Is Nothing Then
MessageBox.Show("PPT is not installed")
Else
MessageBox.Show("PPT is installed")
End If
Any suggestions to solve this issue?
Based on Jimi and TbTinMn comments I solved the problem. I replaced Imports statement by Dim powerPointType and recreated the application instance as follows:
Under Public Class Form1, add
'// PowerPoint automation
Dim PowerPointType = Type.GetTypeFromProgID("PowerPoint.Application")
Dim PowerPoint = Activator.CreateInstance(PowerPointType)
Dim oApp As New Microsoft.Office.Interop.PowerPoint.Application
Dim oPres As Microsoft.Office.Interop.PowerPoint.Presentation
Dim oSlide As PowerPoint.Slide
then you can complete your code with PPT application, for example, Export or Save as
'// open MS PowerPoint with hidden window
oPres = oApp.Presentations.Open(ppt_filename, , , Microsoft.Office.Core.MsoTriState.msoFalse)

I hope someone can help....
I have a powerpoint presentation, which has linked tables and graphs from an excel file. the updating of the slides are set to manual.
i have created a VBA code in Powerpoint which opens up the excel file. I am trying to update the links in the powerpoint through VBA instead of manually choosing each linked element and updating the values. while the first part of my VBA code works in opening up the excel file, the links are not being updated, which i think is down to not being back in the powerpoint to update the links, so I am trying to include in my VBA code lines which will go back to the powerpoint presentation, after which i assume the the line to update links will work (happy to be corrected). below is the code i have built so far....my comments are in bold ...
any suggestions?
FYI, I am using office 2007.
Thanks
Sub test()
Dim xlApp As Object
Dim xlWorkBook As Object
Set xlApp = CreateObject("Excel.Application")
xlApp.Visible = True
Set xlWorkBook = xlApp.Workbooks.Open("File location\filename.xlsm", True, False)
Set xlApp = Nothing
Set xlWorkBook = Nothing
Section above opens the excel file which contains the linked tables and charts
On Error Resume Next
With GetObject(, "PowerPoint.Application")
.ActivePresentation.SlideShowWindow.Activate
End With
Section above i was hoping would go back to the powerpoint after opening the excel file but it does not which is why i think the code below to update links is not working
ActivePresentation.UpdateLinks
End Sub
Start from something easier. This will allow you to activate the first existing PowerPoint application from Excel:
Option Explicit
Public Sub TestMe()
Dim ppt As New PowerPoint.Application
ppt.visible = msoTrue
ppt.Windows(1).Activate
End Sub
Then play a bit with it and fix it into your code.
#Vityata
Ok, i got it to work....original coding did the first part of opening the excel file, and to switch back to powerpoint (and i think this will only work if there is only 1 presentation open i added the following code...
AppActivate "Microsoft PowerPoint"
so my complete code looks like:
Sub test()
Dim xlApp As Object
Dim xlWorkBook As Object
Set xlApp = CreateObject("Excel.Application")
xlApp.Visible = True
Set xlWorkBook = xlApp.Workbooks.Open("file path\file name.xlsm", True, False)
Set xlApp = Nothing
Set xlWorkBook = Nothing
AppActivate "Microsoft PowerPoint"
End Sub
now to get manual links to update as part of the vba code...
If you capture the file that your macro is in. This is just a string of your path and filename
'This is the macro file
MacroFile = ActivePresentation.FullName
Then you can use that variable to activate just that specific PowerPoint presentation.
Use Presentations(MacroFile).Activate
or Presentations(MacroFile).Updatelinks
It's best not to use ActivePresentation when moving between applications.
I am trying to create an Excel Add-in using Vb.Net. I've started an Excel 2007 Add-in Project in VS2010. Sadly, I am not good with vb.net; I am more a VB6 developer in this regard, and my ThisAddin.vb code is:
Public Class ThisAddin
Private Sub ThisAddIn_Startup() Handles Me.Startup
End Sub
Private Sub ThisAddIn_Shutdown() Handles Me.Shutdown
End Sub
' test function; simple
Public Function getRowCount() As Long
Dim thisWB As Workbook = Me.Application.ThisWorkbook
Dim activWS As Worksheet
activWS = thisWB.ActiveSheet
Return activWS.UsedRange.Rows.Count
End Function
End Class
I've also added a Ribbon item (via Add New Item... menu option) in designer mode (not xml) - and then add a button. Then I go to code and try to call the function and I get this error when using:
MsgBox(Globals.ThisAddIn.getRowCount())
Which I got from this link: Calling a procedure within another class
To be honest, I've been trying a myriad things and I've been getting so many errors. I've been looking online as well for a tutorial on creating my own Excel Addin from scratch with no real luck. I would like not to use Add-In-Express since that's a third party app and I have to create an Excel add-in for my company from scratch.
Does anyone have an idea on how I can create a vb.net coded Excel Addin (2007) that I can use as a template or guide? I've tried several and many rely on Add-In-express and I really cannot go that way. I have a lot of VBA code (natural VBA so it's in a module in an my excel files' VBA/Developer section) and I think I can translate those from VBA/VB6 to VB.Net format so that's not my concern. It is really about getting to code my own Excel Addin in VB.Net. Any help would really be great. Thank you.
*note: I would also like not to have to ask coworkers (or do myself) to just add to the quick access toolbar the functions and subs I've created since that's really not a solution, considering that those buttons will be there when they create or open another workbook. Essentially, I've got to create my own excel addin in vb.net. Thank you once again.
The issue has to do with the definitions in Microsoft.Office.Tools.Excel and Microsoft.Office.Interop.Excel. To code an "Interop" version you could use this:
Public Function getRowCount() As Long
Dim thisWB As Excel.Workbook = Application.ActiveWorkbook
Dim activWS As Excel.Worksheet = CType(thisWB.ActiveSheet, Excel.Worksheet)
Return activWS.UsedRange.Rows.Count
End Function
To extend the functionality of the Native objects and use VSTO, you could do it like this:
Public Function getRowCount() As Long
Dim NativeWorkbook As Excel.Workbook = Application.ActiveWorkbook
Dim NativeWorksheet As Excel.Worksheet = CType(NativeWorkbook.ActiveSheet, Excel.Worksheet)
Dim thisWB As Workbook = Nothing
Dim activWS As Worksheet = Nothing
If NativeWorkbook IsNot Nothing Then
thisWB = Globals.Factory.GetVstoObject(NativeWorkbook)
End If
If NativeWorksheet IsNot Nothing Then
activWS = Globals.Factory.GetVstoObject(NativeWorksheet)
End If
Return activWS.UsedRange.Rows.Count
End Function
This is a function you can put in ThisAddin.vb that will create a new Worksheet. Note that this function names the Worksheet and adds it to the end.
Public Function AddWorkSheet(sheetName As String) As Worksheet
Dim wk = Application.ActiveWorkbook
Dim ws As Worksheet = Nothing
Try
ws = CType(wk.Sheets.Add(, wk.Sheets(wk.Sheets.Count)), Worksheet)
ws.Name = sheetName
Catch ex As Exception
Throw
Finally
AddWorkSheet = ws
End Try
End Function
To use this outside of ThisAddin.vb you could do something like this:
Dim ws As Excel.Worksheet
Dim newSheetName As String
.
'
ws = Globals.ThisAddIn.AddWorkSheet(newSheetName)
I have a button on a form in my database that i would like to open a user guide on click. The user guide I have put to gether is in visio but i can't seem to find a way to open it using the macro builder. Is this something i would need to do using VBA? If so any suggestions on how the code should look?
I think something like the following may work, I have manipulated this to fit visio though, so hopefully it works.
Dim FName As String
Dim VisioApp As Object
On Error Resume Next
Set VisioApp = GetObject(, "Visio.Application")
If VisioApp Is Nothing Then
Set VisioApp = CreateObject("Visio.Application")
If VisioApp Is Nothing Then
MsgBox "Can't connect to Visio"
Exit Sub
End If
End If
On Error GoTo 0
FName = "C:\Path\FileName.vsd"
VisioApp.documents.Open FName '
VisioApp.Visible = True
You may need to go in to the VB editor, click Tools > References and then mark Microsoft Visio library as checked.
I'm developing a vb.net application and it should open and handle a excel file.
The problem is that in my pc (and the same could happen in other pc where it could be installed) I have Visio version 2013 and Office (excel, word, etc..) version 2010. Integrating excel in vb is so simple because more or less automatic, done in few steps.. but in the same time so stupid: calling interop.Excel functions, it addresses to the newest version of office intalled (2013), but I don't have excel for that version!
I searched a lot on the web about this issue, and every where I found the solution of deleting a registry key, well, it works fine, but every time I use Visio, it seems the registry key is recreated again.
My questions are:
can I select which version of excel I would like to link my application?
I can understand that fixing the version I should handle any office versions
manually.. but maybe I prefer doing this..
can I copy a dll in the application folder to be sure that the app uses that
version? I tried with Microsoft.Office.Interop.Excel.dll and Office.dll but still the issue
I don't want to follow the way of deleting the registry key programmatically, is not safe in my opinion..
I can't believe that the integration between office and .net is so stupid that is not able to use the right version of excel installed!!
;-P
Code:
Dim fileTest As String = FilePath
Dim APP As New Application
MsgBox(APP.Version)
Dim oSheet As Excel.Worksheet = Nothing
Dim workbook As Excel.Workbook = Nothing
Dim IndexFound As Integer = 0
Dim StartRow As Integer = 10
Dim DateSelected As String = ""
Dim resultOK As Boolean = False
Try
workbook = APP.Workbooks.Open(fileTest)
oSheet = workbook.Worksheets("Activities")
APP.DisplayAlerts = False
oSheet.Range("A2").Value = "test"
oSheet.Range("B3").Value = "Ciao"
Catch ex As Exception
MsgBox("Error: " + ex.Message)
If Not resultOK Then
If Not workbook Is Nothing Then
workbook.Close()
While System.Runtime.InteropServices.Marshal.ReleaseComObject(workbook) > 0
End While
workbook = Nothing
End If
oSheet = Nothing
workbook = Nothing
APP.Quit()
System.Runtime.InteropServices.Marshal.ReleaseComObject(APP)
APP = Nothing
GC.Collect()
GC.WaitForPendingFinalizers()
End If
End Try
End Sub

I am working on a project that requires both an excel document and a word document. I have fully programmed the excel document to work using UserForms, one of which opens automatically when opening the document. (see code below)
Private Sub Workbook_Open()
frmOpen.Show
End Sub
The word document has been programmed to read data from this excel document and write it into a report. (see code below)
Private Sub cmdAutomatic_Click()
Dim objExcel As New Excel.Application
Dim exWb As Excel.Workbook
Dim selectID As String
Set exWb =objExcel.Workbooks.Open("C:\ Path")
exWb.Close
''Data is written into the document here
Set exWb = Nothing
Unload Me
End Sub
The issue is that every time this button is pressed it opens the user form from the excel document and halts the other code until the user form is closed. Is there a way to only have the User Form open when it.
I have tried
Application.EnableEvents = False
However this just returns a method or data member not found (so I assume that this has to be run excel to excel?)
Sorry if this question has already been answered, I could not find anything that addressed this issue. Also sorry if this has a really simple solution, this is for a school project and this is my first time using VBA
Edit:
I realized that doing the following might work
exWb.Application.EnableEvents = False
However because I need to put this before the "Set" for it to stop the form from opening, it doesnt work (as the object is not set at the point the line is run).
You can disable Excel events with objExcel.EnableEvents = False before opening the workbook and reactivate them afterwards with objExcel.EnableEvents = True.
And as #Siddarth Rout told in comments, you can show your UserForm in Modeless mode with frmOpen.Show vbmodeless to avoid blocking other code execution. See MSDN remarks about this : https://msdn.microsoft.com/en-us/library/office/gg251819.aspx
So your code will look like this :
Private Sub cmdAutomatic_Click()
Dim objExcel As New Excel.Application
Dim exWb As Excel.Workbook
Dim selectID As String
objExcel.EnableEvents = False
Set exWb =objExcel.Workbooks.Open("C:\ Path")
exWb.Close
objExcel.EnableEvents = True
''Data is written into the document here
Set exWb = Nothing
Unload Me
End Sub
