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?
View 2 RepliesI'm wondering if you can use the Microsoft.Office.Interop.Excel in a windows service application type.
I've a windows form application which opens an Excel file and do some actions and save it as another file. All this is working perfect in windows forms. When I copy the same code and paste it in a windows service, then it is not possible to open the file even.

Is there any way to insert an existing macro into a existing excel file without using the excel library ? I need this to set the excel to print whole work book .I cannot use excel library because it will be done online in the server where installation of excel is not possible. I can however use the c#.net coding . I am using NPOI to generate the excel.
the macro is given below
Private Sub Workbook_BeforePrint(Cancel As Boolean)
If printed = False Then
Cancel = True

View 1 Repliesi have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

I have a simple Windows Service that reads from an Excel spreadsheet and imports the records into a SQL Server 2000 database table. Before it loads it checks if the file has been successfully imported before (using filename) and whether any of the records in the file have been imported before (using primary key). If these checks are ok I load the records into a datatable and then update the datatable to the database.
However, I need to do this in a transaction as I want to ignore the whole file if there is an error. The file goes to a discarded folder and the user gets an email with why the import failed. (This is likely to be because the store the record is for is not yet added to the database and the referential intergrity of the db fails). If there is no transaction the records before the failure record are imported. When the file is imported again (the store has been added to store table) the file is then rejected because duplicate records are already in the db.

I wrote a UDF to enable users to run Macro`s in excel here is the function below
Private Sub RunExcelMacros(ByVal Path As String, ByVal MacroName As String)
Dim oExcel As Excel.Application
Dim oBook As Excel.Workbook
Dim oBooks As Excel.Workbooks
[code].....
And to use it just call the udf with the 2 parameters like below
RunExcelMacros("c:MyExcelBook.xls", "TheNetMacro")
just remember that you have to have an excel sheet with a macro named TheNetMacro or any other name you want to give it.
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

I can do this using VBA, but I want to be able to create the code using a compiled VB programme, which can then be opened in Excel.

View 5 RepliesI'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
[code]....
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
I am trying to read excel data (Excel 2007 SP1, on Windows XP SP3) with visual basic .net 2008 (VB 9.0 SP1). I have tried several attempts and whatever I do I am getting the following error message: System.Runtime.InteropServices.COMException was unhandled ErrorCode=-2147319784 Message="Altes Format oder ungültige Typbibliothek. (Exception from HRESULT: 0x80028018 (TYPE_E_INVDATAREAD))" Source="Microsoft.Office.Interop.Excel" Message="Altes Format oder ungültige Typbibliothek." Translated: Old format or unknown type libraryI have added the reference "Microsoft Excel 12.0 Object Library" to my project. I am assuming that I might have to add a different or an additional reference, but I do not have any clue which one to use. List of things I have already done:- Searched other forums- Altered the language settings- Tried it on an other Computer (Win XP SP3, Excel 2007, Visual Basic 2008 Express)- Ran the diagnostics tool in Excel - Updated all updates etc...- Reinstalled Visual BasicI really do not have any clue why it should not work?

View 1 RepliesI've been google'ing around trying to look for examples of Windows Services using socket connections but everything has been C# or C++... I know this isn't 100% secure, but I want to do it as a practice: I want to create a Windows Service that listens on a specific port. When data is received I want to parse it as a command. For example, say I send "ring" to the IP/Port running the service it will play ring.wav.

I have this code that works. it goes down a range and deletes the empty rows, seperates the first character into a different column if its not a number or negative sign.This code WORKS. but it is too SLOW for the amount of data i need it to deal with.

I have a macro that save a file under a different name every day with the date as part of the name
ActiveWorkbook.SaveAs Filename:= _
"C:myfile" & Year(Date) & Month(Date) & Dat(Date) & ".xls" _
, FileFormat:=xlNormal, Password:="", WriteResPassword:="", _
ReadOnlyRecommended:=False, CreateBackup:=False
I would like to format the date as YYYYMMDD
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

In Visual Studio when I try to start a windows service project it tells me I cant because I have to use "NET Start" and so forth. I remember in VS 2003 that when I pressed play it started the service and stop stopped it. Is there any way that when I press play or start for that windows service project I can have this same functionality. What I currently do is install them using installutil and I put a pre-processor command with System.Diagnostics.Debug.Launch() when I have a compilation variable defined and when I use the service manager it shows me the window to select the debugger. Still this method is somewhat cumbersome.

I can get the service to run through my code once, but I can�t get it to loop, well I can but then the service will not start correctly and just times out while the code is running.
How can I get the service to start and then loop, at the moment it just says starting service and the code is looping but the service wont start! Windows times it out after a few mins.
