Users Pressing Run In The Excel View Macros List Corrupts The Workbook?
Sep 26, 2011I need to stop users from running macros from the View Macros list. I have a security program that stops editing the macros but allows selecting the macros and running them.My code is too long to go into a single procedure. It fails to run and I got the following information when clicking the Help button:
***Code for this procedure exceeds 64K when compiled. ***Break this, and any other large procedures, into two or more smaller procedures.If I split the code into 2 macros, the user can press Run in the View Macros list on the 2nd macro which then corrupts the workbook.

Merge Multiple Excel Files Into One Excel File And It Works For 3 Source Files But Its Not Working If Workbook With Worksheet Count Is > 3?
Aug 18, 2011I'm trying to copy multiple excel source files into one excel file. My current code is working only for 3 source files..If more than 3 files are there, it doesn't copy the data but creates blank work sheet in the output excel file. Lets say I have a source folder with 5 excel files. Each workbook contains one worksheet with data. It copies upto 3 worksheets along with data into output excel file.
Lets say excel1 contains A as work sheet, excel2 contains B as work sheet ,excel3 contains C as work sheet ,excel4 contains D as work sheet ,excel5 contains E as work sheet .Now my output excel file should look like..OutputExcel with A, B, C, D, E along with respective data.But my current code is giving output as A,B,C worksheets along with respective data but its creating blank sheet1,sheet2 in place of D & E.

May 16, 2010In the following code why does the message box display behind the workbook,instead of on top of it? It does this related to the line, app.Visible = True. if this line is commented out the message box appears in front, but there is no workbook visible. I've used the message box in other places without a problem. Is there something fundamental here that I'm missiing?

Mar 25, 2011My question centers upon the two approaches, (1) and (2), shown below, to declaring Excel workbooks in .Net.The two approaches interact differently with the lines "wkbk10 = app.wkbk10.open()" and later with

Multithreading Errors With Excel Workbook?
Aug 26, 2009I have a .Net program that responds to worksheet updates of an Excel 2003 workbook. Sometimes when the worksheet is updated and I try to write related data to my forms, I'm getting "Cross-thread operation not valid...." errors. This confuses me, as I have never done any multi-threading in my program. Does the mere act of me responding to events of an external excel worksheet mean I am now multithreading? Is there a way to handle the events without multithreading?

Using VB To Find A String In An Excel WorkBook?
Aug 28, 2010I am working on an application where I need to locate a range of cells within a worksheet. Since the actual location of the data will vary for each worksheet, I have come to the conclusion that I can put a string near the range that I am looking for (i.e. the text "*SUMMARY*") and since I will know the location of the data that I am looking for relative to the location of this text string, it should work.
I have made some progress but am having trouble getting the Find method of the range component to work. My code is below. This code finds each worksheet and shows me the name but I also need to to find the location of the cell with the string "*SUMMARY*" in it (if it exists).

VS 2010 Program With Excel Workbook?
Feb 21, 2011I have a little problem with a small application that uses an excel workbook, and i don't know what's the best way to handle this.In the past every computers here in the company had the same culture and the same office version/language.Now the company bought some new machines, that came with english version of the office (en-US). Now the program doesn't work, throwing the exception related with the assembly of the office.
I have two solutions to solve this, install the mui in all the computers, or the one that i want, adapt the application to work independent of the culture in the client machine.So how to accomplish this? Set the application culture to the same culture in the computer (i think this will not work, because the excel assembly that i ship with the application isn't the correct one for the client language it's the assembly of my machine language)... One copy for each language, once again it's not possible

Excel - Open A File In An Active Workbook?
Aug 19, 2010I have a program that filters data and then outputs it to a tabg delimited file. I then use Excel Interop to open this file in Excel because directly outputting to a worksheet takes too long. So currently I am using this code:
AD.DF.WriteToFile(vbTab)
Dim WB As Workbook = ExcelApp.Workbooks.Open(AD.DF.DatafileInfo.WriteToFileLocation)
ExcelApp.Visible = True
The first line takes the filtered data and outputs to a tab delimited file. The second opens that same file in a new workbook in Excel. And obviously the third makes Excel visible. Here is my problem though: right now when this code is run there are two open workbooks. I already have an active workbook and I would just like to open this file to that workbook.

VS 2010 Open Active Excel Workbook?
Aug 8, 2010I am finally switching from VB6 to VB Net and am rewriting a technical application that calculates the heat transfer performance of automotive radiators, heater cores, evaporators, condensers, etc.The user can calculate a heat exchanger and save the results to an Excel spreadsheet. After a series of calculations he can then plot curves of performance.
He can also click on a previous calculation in Excel and import it into the VB routine. The user may have a number of workbooks open when he does this.My problem is I need to open the Excel workbook that is the active workbook. I have been able to select the active worksheet but have been forced to specify the index of the workbook. I have not been able to get the workbook I want.. The code I used is the following,
Dim oExcel As Object = GetObject(, "Excel.Application")
Dim oBook As Object = oExcel.Workbooks(1)
Dim oSheet As Object = oBook.activesheet
How do I get the active workbook instead of Workbooks(1) with an index of 1?
