All I would like to do concatinate text from two different cells using VB Express 2010. I know there is a =A1&" "&B1 Funtion if I were using excel an thier is also the concatinate function but I do not know how to use these in VB. Below is what I have so far for simply copying one cell to another.
title =

Excel.Worksheet).Range("A1")

I'm trying to write an import function for getting data out of an excel file. How I currently do it is as follows:
Private Sub ReadExcel(ByVal childform As PhoneDiag.frmData, ByVal FileName As String)
Dim xlApp As Excel.Application
Dim xlWorkBook As Excel.Workbook[code]....
From what I can gather, it more than likely comes down to this line:
Dim Obj = CType(therange.Cells(rCnt, cCnt), Excel.Range)
All I need is the text from the cells, not to create an object for each cell (and then not send them to garbage collection).Is there an easier way of just getting the text? Ideally, if I can get a method for getting the text values of the cell, I'd like to get the multiple rowArray()'s added to a master array and update the program's values later.
EDIT:I also realize that I have two options if I were to create a master array, say mArr, to hold all the data.Would it be better performance-wise to have mArr to be large and the sub arrays small, or mArr to be small and the sub arrays to hold more of the information?I ask because the files that will be imported will have more rows than columns, so I was wondering if there was any "set" way of doing it.
I have a text file with the following contents:
China,Asia,100000,3500000
England,Europe,20000,49494
USA,North America,430933,33943
Brazil,South America,754744,74744
How can I export all these under the headings to Excel:

My main goal is to have an excel spreadsheet that automatically plots the overall success of my stock portfolio over time (% change over time). I've been able to incorporate stock data into my spreadsheet by linking it to the web, but the trouble is the spreadsheet will keep no history of what the previous stock values were, so I can't graph how things change over time. This sounds like it might be too complicated to be built in to excel, so I was wondering if anyone knew how to program this in Visual Basic. Maybe something like this.... If refresh then new cell plus new time stamp. Another possibility would be to have a whole bunch of cells that refresh only once but at longer and longer intervals, e.g.,

Now, the goal is for the end user to be able to fill out the form, and save it as todays date. How does it get todays date? In the Excel sheet, N2 is todays date, and it gets it from the form. Then save it in a specific folder.
