IDE :: How To Deal With Cells Excel Cells That Update Info Via The Web

Jul 5, 2009

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.,

Office Automation :: Word Table Merge Cells And MoveRight?

Feb 24, 2011

I've searched for this everywhere, but can't find a solution after trying for two days. What I want to accomplish is creating a table in Word (n-rows, and 3 cols,) (which I successfully have) and for each row that has a new date, I want to merge all three column cells just for that one row with the date. For every other row, above and below, I still want to preserve the 3 columns structure. What happens with the Merge() method is that all the rows merge, not just the row I'm currently on. I did a macro and noticed that there is a Selection.MoveRight() option I can do, but I can't yet figure out how to put all these statements together to accomplish this. When I do the MoveRight, trying many variants like the following:

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, 2011

I'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.

C# - -copy A Formatted Cell In Excel To A Table Cell In Word Using .NET?

Apr 20, 2010

I'm attempting to copy cells, one at a time, from an Excel 2003 (or 2007) spreadsheet to a Word 2003 (or 2007) table. I'd like the code to be version-agnostic, and so am using late binding. The formatting of the contents of the Excel cell, such as color, underline, strike-through, needs to be preserved. My approach is to use a Word doc as a template. It has a table at the top which I can copy to the end of the doc, add rows as needed, and fill in the word table cells with the data from the excel spreadsheet. Unfortunately, all the formatting disappears. All I get is the text itself.

Im using the following code:

oApp = New Outlook.Application()


This does not copy the cells. It simply displays an email with a body that says "true".

Getting The Text Value Of Cells In An Excel (*.xls) File?

Nov 6, 2009

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.
