User Can Choose Excel Cells To Read

Oct 5, 2009

I want the people using my program to choose their own cell to read. I will have 2 textboxes (txtRow and txtColumn). They will have to click "read" to read from excel (but I will not open MS excel) and the answer will show in a message box. This is what I have done..

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCheck.Click
Dim conn As New OleDbConnection("Data Source= D:LeeABC.xls ;Provider=Microsoft.ACE.OLEDB.12.0; Extended Properties=Excel 12.0;")
Dim da As New OleDbDataAdapter("Select * from [Sheet1$]", conn)
Dim dt As New DataTable
Dim Row1 As Single
Dim Column1 As Single
txtRow.Text = Row1
txtColumn.Text = Column1
da.Fill(dt)

Read An Excel File - Loop Through Cells To Get Values?

Jul 25, 2008

I'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?

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.,

Add Textboxes To Gridview Cell On Edit Select?

Sep 23, 2011

I could really use some help on this. I have been searching for a solution on the web but haven't been able to find much help.I need to add textboxes to a gridview edit cell, based on the number of rows of text in one of the cells. I have coded the capture of the number of textboxes I need to add.

But I am not sure which Gridview event to add the code, when going into edit mode, to run the loop that will insert additional Textboxes in a specific column of the row selected to edit.

The user sees colA that has text with line vbCRLF's embedded say:

"This is sample text."

"Line2"

"Line3"

My code reads three Carriage Return, Line feeds. So when the user goes into Edit mode I want to provide one text box for each line or more accurately, add two more as one will already exist.

VS 2008 Edit/update Records From The Database Using Textboxes By Linq To Sql?

Sep 26, 2009

This is the hardest part of LinqtoSql database handling operations in visual basic 2008 I ever encountered,w/c is the update operation cause Ive been posting this thread several times from the other forum site but noone yet was able to answer my question,examples were given but its not efficient cause it won't specify based on the codes i gave and i know its not easy but im still hoping that one of the answerers of this forum will be able to resolve this particular linqtosql operation codes. I used textboxes in manipulating all data into the database such as displaying records, adding records, & updating records, basically I used with textboxes in doing those database operations. I will give you 3 block of codes w/c corresponds those database operations I used and differentiate from each other inorder for us to determine why one of them has no progress or won't do its operation w/c is the update operation...

*************Block of Codes#1(Adding Records)*************
Private Sub Button1_Click(------------------) Handles Button1.Click
Dim db As New memrecDataContext()

[code]....

I would like you to identify,differentiate, or troubleshoot the block of codes#3, or anyhow, why it has no progress at all or it won't edit and change the records but it runs and no error in regards with its code, and the other 2 blocks of codes were able to successfully do its operations.I was just wandering why only the block of codes#3 is not doing its operation successfully when you change the record being displayed in the textbox.Is there a possible way to edit records in the textboxes?If there is.... Is it possible to debug the block of codes#3 to successsfully do its operation? If you could possibly give an example,can you based it on the block of codes#3?

I has some vb.net code to export some data into Excel format. I had set one of the column to date format. But I want to avoid user from changing the format because they can easily right click the Excel cells, and choose Format Cells. How can I disable this option in Excel via vb.net code so that user will always follow my format?

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.
