Creating A Program - Send The Data To Be Stored In An Excel Workbook ?

Feb 13, 2010

I have a macro run program I have created using excel 2007.The excel version makes use of VBA designed userforms and macro code to run and it stores data within a worksheet.It populates some of the fields in the userforms from drop down boxes whose pre-populated values are stored within another worksheet in the workbook.If I was to create this within vb.net how would the drop down box values be stored? and also: would it be easy to have the userform on-close click event send the data to be stored in an excel workbook ?

Error Creating Directory And Saving Excel Workbook On Vista?

Mar 2, 2008

I have a VB.net applications that runs on XP and creates a directory and creates an Excell workbook and saves it. But when I do the same in Vista , when it tries to create a directory to save the excel workbook, it gives me an error that the directory does not exist. If I create the directory manually, it still gives me the same error. Is there a COM call for office 2007 on Vista other than worksheet.SaveAs(FileName:=path). All else works on Vista apart from creating a directory and Saving Excell Worksheet.

VS 2010 Program With Excel Workbook?

Feb 21, 2011

I 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

Chart Control - Creating Graphs Using Crunched Data Stored In Array List

May 7, 2010

Recently I have learned visual basic 2008 express edition and developed programs for data crunching and analysis. The VB 2008 express edition has microsoft visual studio 2008 v. 9.0.30729.1 SP and .NET Framework version 3.5 SP1. Now I want to create x-Y (date-Y value) graphs using the crunched data stored in an array list simulating a data base access. I download and installed the "Microsoft Chart Control for .NET Framework " and try to learn to use it within the VB 2008 express edition using the tutorial. It seems that the chart control did not get installed?

1. Do I need at VB 2008 professional to allow using the chart control?
2. Why after installing chart control, there is no change on the items under the NET components within the Toolbox>ChooseItem>.
3. How do I get to use the chart control under VB 2008 express edition.
4. Any code available to generate versatile graphics without using the chart control? Because the chart control has tons of classes already it seems the best is to just use the existing and downloadable chart control?

Why Is The Message Box Behind The Excel Workbook?

May 16, 2010

In 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?

Declaring Excel Workbook In VS/VB 2010?

Mar 25, 2011

My 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

Range references to this workbook,like "rng1Stocks = CType(wkbk10.Sheets(1), Excel.Worksheet).Range("H5:H30")".

Multithreading Errors With Excel Workbook?

Aug 26, 2009

I 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, 2010

I 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).

Excel - Open A File In An Active Workbook?

Aug 19, 2010

I 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.
