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.
Office Automation Excel - Call App Via A Key Combination
Mar 29, 2010I have a vb.net app that retreives data from a MS SQL 2005 database. I have it creating an Excel 2003 workbook. In a cell of a Worksheet, I want to "Call" or make active my vb.net App via a key combination (Alt->V) and have the workbook/worksheet pass the Row number / Column to the vb.net app that will get the data and post back to this Cell. This combination (vb.net and Excel) is my report builder app. So I want to go back and forth between vb.net and Excel, passing the needed data from each. How can this be done?

Office Automation :: Excel 2003 Automation With VB 2005 Express?
Apr 20, 2010Ok basically what I need to do is the following:Read FirstExcelDoc (attached)For every row in that: Retrieve data from sql server db based on info in the Orange columns of FirstExcelDoc Let's say I retrieved data elements A, B, C, D, and E from sql server. Then I need to enter those same data elements A, B, and C in another excel spreadsheet (which has formulas etc) After inputing A, B, and C in that spreadsheet, read a couple of calculated fields and compare those results to data elements D and E retrieved originally from SQL Server DB. Finally, output the results in the Blue columns of the FirstExcelDoc spreadsheet for that row.Loop through and do the same thing for row 2 of the FirstExcelDoc and keep on until you see "END TEST" in the FirstExcelDoc.
I'm looking for a method of doing this efficiently. I have read several articles over the past few days as well as those from Mike R. but just need some direction to get started on this.To start of I'm looking for whether to read the entire FirstExcelDoc spreadsheet or just read the info for first policy number(2nd row) and process it and write out the blue column info for that row and then loop through and come back and read the second policy number (3rd row) etc... Please attach a code snippet for either way of reading the data.
Office Automation :: Orphan Excel Process Started Via Automation
Jun 17, 2009I'm using excel via interop in application.Sometimes users kill application that created excel instance and that results in excel instance sitting in memory without any chance of disposing it.First I tried to tackle this using ROT(running object table) looks like not all instances of excel are registered there.Than I tried to somehow mark excel process after it is started via interop.[code]This works as long as excel is visible but in my case excel window is invisible.All I need is to somehow mark process that started via automation with the parent PID, so that later I can kill it if parent does not exist.

Jun 1, 2010We have a vb program which is run on our server by scheduled task every day. The program opens about 30 excel files, refreshes the data connections, pivot tables and then saves the document in another location.
This may run fine for a couple days but sooner or later the process starts crashing, usually with this error: RPC_E_SERVERFAULT.
My question is, Is it expected that continually opening/closing/refreshing workbooks will inevitably cause the Excel object to crash at some point.
Office Automation :: .net Automation Excel App Not Closing
Sep 25, 2009I'm having an issue where my excel.exe process doesn't close until I close my .net application. I'd like to avoid using Process.Kill() if at all possible.
Code:
Private Sub WriteRowsToXls(ByVal rows As DataRowCollection, ByVal xlsPath As String, ByVal showStatus As Boolean, Optional ByVal AddTotals As Boolean = True)
Dim xlsApp As New Microsoft.Office.Interop.Excel.Application
[CODE]............
This method references a couple of other methods I use for repeated formatting tasks, I'll include those methods below. (I added the FinalReleaseComObject into the other methods after reading Mike's thread but the issue persists)
Code:
Private Sub SetRangeValidation(ByVal rng As Range)
With rng.Validation
.Delete()
[CODE]..............
Method SetRangeAllBorders does about the same as these other methods but my post is too long to add it. The only other things not shown in these code snippets are a few string variable that are defined in the class, studentWS, studentsWSPW, paymentsWS and paymentsWSPW My App creates an instance of the class, loads some data, runs the method above, and then sets the class to nothing. I'm using .NET 3.5 automating Excel 10
Office Automation :: Excel Automation - Cannot Use Office PIAs
Feb 14, 2009It appears that when one creates an instance of Excel, using CreateObject, (Late binding), the suggested Excel closing function (with GC.collect etc) does not work. I have tried several suggestions, and the only one that works is process.kill method. Do you see any problem in using this? BTW: the reason we are using late binding is that we cannot use Office PIAs....not sure which version of Office would be installed on the client site. We work with O2003, but the client might still be at 2000 or 2002.

Mar 28, 2011i was wondering if someone could give me the final explanation on what i might be doing wrong here.I spent a lot of time reading around the net and the forum about how to add Threading capabilities to a VB project.
Nos, i've got .NET 4 installed, and i've added the system.tsr and mscorlib.dll files as reference in, say, Excel 2007 (see screenshot).However, when i try to make a thread with anything as basic as "Dim Thread1 As System.Threading.Thread", i get a user-defined type not found error.Indeed, when i use the object browser to see what's in the System file, theres nothing remotely linked to any Threading, and in the mscorlib file, nothing under "Threading" either, just a few Thread related functions, but nothing defining a data type

Office Automation :: Call A Spreadsheet Dependent On The Day Of The Week?
Sep 16, 2011I have a slight problem , using vb 2008 i have written some code that checks the current datetime on the computer. This gives me the answer in the format mon, tues etc. what i now want to do is to use that to call a spreadsheet dependent on the day of the week. here is my code so far
Code:
Dim TIME As DateTime = DateTime.Now
Dim FORMAT As String = " ddd "
TextBox1.Text = TIME.ToString(FORMAT)
[Code]....
Now i have tried the private sub eg SATS() on a separate button and it works perfectly . so it appears to be that the sub is not been called. I think it is probably a syntax where the datetime answer is not been recognised, in that textbox1.text = "sat" is not the same as datetime = sat .

View 4 RepliesOffice Automation :: Excel .NET Interaction Via DLL?
Dec 7, 2010I would like to keep part of an Excel workbook open to the user (including some VBA code) while protecting other code. What I hope to accomplish is to rewrite some of my code from Excel VBA in VB.Net and compile it into a DLL which I can then call from Excel VBA. I want end users to be able to modify most of the code in the module, but some of the process should never be touched. Say I have an array in VBA
ArrONE(1 to n, 1 to n)
I would like to pass this through into a DLL and return a new array back to VBA:
ArrTWO(1 to n, 1 to n)
1) What are the best resources for VB.Net?
2) What are some main differences between VBA and VB.Net code
3) I have read that VB.Net doesn�t handle Variant data types, which (as far as I know) is a requirement to perform matrix multiplication in Excel VBA. Any detail on this issue would be of use.
4) VB.Net test environment? I often use msgboxes or simple subs printing to a spreadsheet to test my code in Excel VBA as I go to make sure everything I code is working properly before advancing. What would be .NET equivalents.
5) How to compile VB.Net into a DLL
6) How to call a DLL from Excel VBA
7) What effect will this have on the speed of my procedure?

Office Automation :: Excel Program Leaves EXCEL.EXE Floating After Completion
Feb 24, 2012I am writing a program that loops through all of the sheets in an Excel workbook and saves each sheet as its own workbook. It turned out to be a bit trickier than I expected, since the Sheet.Copy method creates a strange object (see here for the MSDN discussion that I believe is relevant: [URL]. Anyway, I found a Stack Overflow post [URL] that got me to where I am, which is essentially complete, outside of one hanging EXCEL.EXE process that is left after the program completes, which I believe is a result of the sheet.copy method creating a new workbook (potentially a new application as well?). The other thing I run into, which I believe is related to this, is that even though I have my application set to visibility off, when I run the program, excel still opens up and is visible going through the steps.
Here is my code:
Code:
Imports System.Data
Imports System.IO
Imports Microsoft.Office.Interop
[CODE]...
Now I think the problem comes from the end of the loop, where I try to close the export file and the new worksheet it creates:
Code:
'close excel and release com objects
System.Runtime.InteropServices.Marshal.ReleaseComObject(exportsheet)
exportsheet = Nothing
xlApp1.Workbooks(fileNames(counter - 1)).Close(False)
I can't figure out what to do to release the `ComObject` for the new worksheet that is created. I have been trying all sorts of things, but it always throws a COM error when I do it and if I try to define it as nothing (like I do with exportsheet) is says that it is read only by default, so I can't do it. It seems like it should be something as simple as: System.Runtime.InteropServices.Marshal.ReleaseComObject(xlApp1.Workboo ks(fileNames(counter - 1))) But that is not the case. I have tried a few variants of this and I am thinking it has to do with the MSDN link above, but I can't quite sort out what to do. So the code works for my purposes, outside of leaving one EXCEL.EXE after it is done. As far as a test file, I am just using an Excel file with 3 sheets and I put some information on each and change the sheet name, so it is easy to see if it is working or not.

Office Automation - Excel Range References
Apr 22, 2010I want to define a range in Excel, but I do NOT want to use "A" or "D" references for columns. I am making a table, and to set it's range I use:
Code:
.Range("A1:D4")
However, at the time i write the code I do not know how many columns will be involved, so I don't know if "D" is the end column. For rows this is fine, as i could write this:
Code:
.Range("A" & i & ":D" & j)
But how do I do this for columns? I really would rather not have to convert my integer number for the end column to text. If I know that the table should go from row 1 to 5 and column 1 to 10, how to I select this range?
Office Automation :: .NET Add-in Does Not Work With Excel 2002
Jan 22, 2009I have created a C# .Net DLL add-in for Excel.When I try it on my home machine with WinXP and OfficeXP 2003 it works as expected. When I try it on a couple of machines at work with WinXP and OfficeXP2002 it does not work.I have spent 2 days solid reading up on this subject in general and I still cannot get to the bottom of the problem. As far as I can work out what I am trying to do should work with Excel 2002.
Some details:
- I am using Visual Studio EXPRESS 2008 (C#).
- The assembly is signed with a Strong Name Key File.
- I have installed the OfficeXP (2002) PIAs.
- I have created a class DLL in accordance with many MSDN and other internet posts.
- I have registered the DLL using RegAsm.exe and GACUtil.exe.
- I have added registry entries for Excel for CURRENT_USER so Excel should know about the DLL.
The DLL adds some Automation functions (Tools-Addins-Automation) which can be accessed in cells within Excel (for example you would enter =MultiplyFirstBySecond(2, 3) in a cell and get a result of 6) and also implements the IDTExtensibility2 methods so that when Excel is opened it creates a button on the toolbar which when pressed pops up a message box. It it this functionality (adding buttons with code behind them) that I want to expand on.I have attached the zips of the batch and registry files I have created to register the DLL in the GAC and in the registry. I have also attached a zip of the complete project. I would like to know if there is anything I should check with my machine's setup or my project or my registration/installation of DLLs, PIAs etc in order to make my DLL work on my Excel 2002 machine.
Office Automation :: Custom Color In Excel?
Aug 17, 2009my program lets people pick their color to highlight different shifts.after data manipulation they can export the shifts to Excel.I want Excel to show up the same colors as the users picked so I know I need to add them to the workbook palette.the first color I import works fine but after that, all the colors get jumbled and messed up and put in random spots in the palette
WorkBook.Colors(paletteIndex) = RGB(dColor.R, dColor.G, dColor.B)
leads to
Excel.Cells(i, j).Interior.ColorIndex = paletteIndex
something must be wrong in these two lines. I get no errors, just the wrong set of colors.
