Office Automation :: Excel File - Set A Reference To The Microsoft Excel 12.0 Object Library

Oct 6, 2009

I'm trying to upgrade a VB6 app to VB 2008. I have read the article in the tutors corner about automating Excel from VB but I cannot get it to work. Heres what I have done:

1) set a reference to the Microsoft Excel 12.0 Object Library

2) Added "Imports Excel = Microsoft.Office.Interop.Excel" to the top of the module

3) in a routine I have added: Dim X As New Excel.Application Here's where I get an error: Error 75 'Application' is ambiguous in the namespace 'Microsoft.Office.Interop.Excel'.

Display Excel File (even If Excel Is Not Installed) Library? Method?

Mar 5, 2012

I have a project that has a need to display a Excel file in second window, but because other controls are needed, simply launching excel is not sufficient. Right now I do not know if the target machines have excel installed but I know with certainty that if they do it would be 2010, is there any method or library that allows you frame your own form around an excel window?

Using The Microsoft.Office.Interop.Excel.dll Library; Does Excel Need To Be On The End User's Machine

Nov 22, 2011

I have been doing a lot of reading on this topic and most folks seem to agree that having Excel is required to use the COM Interop libraries. However they are never specific as to where that should be installed. Does it need to be installed on the machine I am developing on or does it need to be on every machine that I deploy to?

Edit: I should mention that this is desktop development/deployment targeted for all Windows machines.

Quit An Excel Macro Externally (from A GUI Not From Macro)

Oct 21, 2010

I'm have a program (GUI) that interfaces with excel to execute macros. We're using Microsoft.Office.Interop.Excel to call/run the macros and this works great.What I can't figure out is a good way to cancel the macros from the GUI.One idea we had was to use the excel.application variable that runs the macros to write a "stop" value to a specific cell in the workbook, and in the macros (they are all mostly loops), check for the "stop" value in that cell. This crashes my GUI with this The program '[2188] BVLReports.vshost.exe: Managed' has exited with code -336589910 (0xebf00baa).And excel gets tied up, and won't respond. I know how to Exit Sub from within the macro if the "stop" value exists, so I don't need answers on how to check/cancel from inside the macro. Any ideas on a better way to write this "stop" value or a better way to cancel the macros externally?

Excel To Powerpoint Macro - Copying Excel Range And Pasting As HTML Or Default In Powerpoint?

May 11, 2011

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
Range("CP12:CT" & RangeIndex2).Copy

Excel 2007 Macro - Runtime Error 1004 After Saving And Re-opening A File

Oct 25, 2009

I have an Excel file with utilizes macros to allow a user to enter names of people and then double click on cells to enter ratings via radio buttons. When I open a blank file and enable the macros, I can add users, rate their skills using the radio buttons, etc. with no issue. I then SaveAs the file and continue working on it. once I Save and CLOSE the file, then go to re-open it, the trouble begins. Keep in mind, there is no alteration to the macros directly. Just entering data and using the form as intended. Here's what happens.

I reopen the file.I enter in the name of a person on one line.  I go to the first box - double click on it.It is supposed to pop up a dialog box which allows me to choose a rating via radio button (as I had been doing before I closed the file).  Instead, in that first column of ratings, it instead gives me the following error:

Runtime error '1004'Unable to set the LineStyle property of the Border class

When I hit "debug" this is the code it points to:

If ActiveCell.Column = leftb Then Range(Cells(ActiveCell.Row, leftb), Cells(ActiveCell.Row, rightb + 1)).Borders(xlEdgeTop).LineStyle = xlContinuous I have no idea why this would not work when I re-open the file!

note that when I go to click on the subsequent cells (there are 8 cells in which you provide ratings, moving across the columns with each cell) - the 2nd through 8th cells function fine. The dialog box pops up, the rating can be selected.  it's just the FIRST cell that gives the issue What would possibly be the cause of this? We need users of this form to be able to save, close, and re-open it if needed.

VS 2005 : Error In Opening An Excel File : Old Format Or Invalid Type Library

I am trying to open an Excel file using the following commands:

where 'filename' is the name of the file.However I am getting the following error message:

Message = "Old format or invalid type library. (Exception from HRESULT: 0x80028018 (TYPE_E_INVDATAREAD))"

I originally developed an application where I used the above code with default language setting of "English" (under regional and language settings). When I am changing the language setting to "French", the above errror comes up. I am changing the language setting to French in order to simulate an error when this application is run in a French version computer.

Creating A Macro In Excel Using Vb?

Feb 24, 2010

I'm creating a macro in excel using vb?What the macro is doing is checking if the row and column headers are same, and if it is then I want it to save the row header (the date in this case) AND the value (a number) into an array, and this is done in a for loop and goes on.... I dont know if I should use 2-D array or a 1-D array that stores 2 values....Not sure at all !Then after the outer most FOR LOOP is done, I want to print those values stored in the array.

Here is what I have so far, this works actually however i'm using 2 seperate arrays, one to store the row header (the date) and another array to store the value.  But really I want to make it simpler, shorter and use only one array that stores both of these values as we go through the for loop and at the end of the for loop, all the values from beginning which are stored can be printed out.

Here is my code :

Sub Test ()
Dim sys_arr() As String  ' declaring the array to store the values
Dim sys_date_arr() As String 'declaring the array to store the dates


This totally works but with 2 different arrays, all I want is just 1 single array (not sure if it is 2-dimensions or still stays as 1 dimension but with 2 different variables)... and then the array can store the date and variable correspondant to the date, and goes to the next row, and do same thing... So the output results should be like  for eg :

2/12/2010  37
2/13/2010  41
2/14/2010 66
and so forth

Macro In Excel - Increasing Values By 10 Percent

Apr 25, 2010

I'm guessing the reason this macro isn't doing what I want it to is because of an error on my part in the code. Basically, I want the values in the cells pointed out in the code to be increased by 10% each time the button is pushed.

Here is the code:
Sub Add10percent()
IncreaseColumnValuesBy10Percent 2, 0.1
IncreaseColumnValuesBy10Percent 4, 0.1
IncreaseColumnValuesBy10Percent 6, 0.1

Excel 2007 Macro Opens Access Db But Then It Disappears?

Can anyone tell me how to fix this?  Here's the code:

Find Repeated Keywork On A Cell - Excel Macro

Jun 29, 2012

On my VB excel macro, I am trying to create a code to search a key word on a specific row and to display the adjuscent 5 cells values in a text box. That keyword will be repeated here and there on that same row. But the adjuscent 5 cells value will be differ each time when the keyword matches.

For example: Row 20 has a word "We gave" (key word) in cell D20. I want a textbox to display the values of E20, F20, G20, H20, I20 in a text box. Then on cell M20, there will be another "We Gave". Then it should keep the value that it displayed in the text box earlier and to show the newer values of N20, O20, P20, Q20, R20.

Call/run Excel Macro Within A Separate Visual Studio Application?

Dec 14, 2010

I'm looking to call an excel macro (excel version 07) within a separate visual studio application (visual studio express 2010). Basically, a user clicks a browse dialog button to select a xls or xlsm file which is then added to a listbox. Next, I would like the macro to run when another button is clicked. The macro looks at the first column in excel and moves the listed .tif images from one folder to another. I referenced the excel libraries, but seem to be getting hung up on a few code statements (''''ERROR see code below). I would like to run the macro within visual studio for any selected excel file or add the macro somehow to the selected excel file and run it.

'Here is the button click procedure

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
filenames = lstFiles.SelectedItem

Office Automation :: Run Excel 2007 Macro From Custom Button

Jun 10, 2009

I have used Visual Studio 2008 (VB) to create a custom tab and button group with custom buttons. When any of those buttons are clicked, I simply want to run a macro (add-in) that will already be loaded when Excel is launched. The main examples I've seen create an Excel object in the VB code and then call the macro, but that seems like unnecessary overhead, since the custom buttons are are already loaded into Excel.

Office Automation :: Code Hangs When An Excel File Is Opened To A Excel Workbook Object?

xlWorkBook_new = exlapp.Workbooks.Open(strOriginal)

The code hangs in the last line. It works fine in the development environment. i deployed in windows server 2000 ,where I get this issue. the browser goes half way and throws the below exception after some time


I have set the identity impersonate to true in web config. This should be mostly an access rights issue.I have even provided access rights for the "everyone " user in the excel file and as well for the interop component. Please post ur valuable comments.

Open Excel File And Reusing Existing Excel Instance?

Jul 13, 2010

I have an application the contains several excel files bundled with it. I'm not opening the files and processing them within my application. These files contain a data-connection to reload all of the pivot-tables within each excel file. I have a 'link' on my form, that when clicked, it determines which file to open and calls a sub using filename and executing Process.Start(filename) for any excel file I want to open. I have no problems opening any one of the files and then exiting excel.

The problem is when I 'close' a file, but don't exit Excel; then try to open another file(clicking link on form)... it creates a new instance of Excel.

I know from experimenting that the fileopendialog form will 'reuse' an existing Excel instance, IF it does not already have a file open.

How can I do the same thing without using the fileopendialog?

I don't want the end-user to have access to the folders where these files live. That's why I have multiple 'links' on my form, one for each xls that already exists. I just want them to be able to click on a link and the xls file opens AND if they choose to merely 'close' a file and not exit... Don't create a new instance of Excel, but re-use the existing one.
