Read An Excel File - Loop Through Cells To Get Values?
Jul 25, 2008I'm using VB.Net's Excel component to read Excel file, but the performance is totally slow, since it has to loop through cells to get values. Reading a file containing one sheet with 1162 rows and 105 columns (which is small size compared to my general requirement) already costs more than 5 minutes.1. I want to ask if any of you have suggestion on reading such an Excel file with better performance, except OleDB, cuz most compies here have vesion problem?2. Is it normal that it tooks a long time for Excel component to read Excel file, or is it that I implement the code in a wrong way?

Change The Entire DGV Back Color To Something Else (including Those Cells)?
Aug 2, 2011If i have a DGV where i change the color of some of the cells like this...
DataGridView3(0, 1).Style.BackColor = Color.DimGray
DataGridView3(5, 3).Style.BackColor = Color.DimGray
DataGridView3(6, 0).Style.BackColor = Color.DimGray
is there a way i can change the entire DGV back color to something else (including those cells)i tried DataGridView3.DefaultCellStyle.BackColor = Color.Indigo but that does not seem to work on the cells already colored. Im guessing this is because im only changing the default cell color?

Getting The Text Value Of Cells In An Excel (*.xls) File?
Nov 6, 2009I'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.

Jul 5, 2009My 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.,

Convert Font Size To Control Size?
Aug 10, 2010I'm writing a couple of custom controls in VB.Net 3.5, in VS2008, and would like to resize the font size based on the height of the control, and vice-versa. Is there any way of converting a font of say 38.25pts into a me.height, or the other way round?
I realise the font width will change dependent on the font used (which isn't an issue for my purposes), but as far as I know, the font height is usually consistent Accessibility/Large font settings won't be an issue with this application.
