Is it possible to take an Excel spreadsheet and move some columns around? Basically I receive spreadsheets that need to be re-formatted and have the columns shifted, some also need to be deleted. I have no idea how to go about this, is it even possible? It's always the same columns so it's not like it changes from file to file. I know it probably makes more sense to just create a macro but I thought I'd see what was involved in it anyway.
I have an excel sheet with one of the columns as name .There are many rows with same name and I wish to mail all the rows with same person name to that person(given there is a column specifying email address).
I am retrieving the data from AD and sending it to th CSV file. but the data is not coming in Column1,column2 and Column3. Can you guys help me with formatting.[code]When i export the data to Excel the 3 fields i am retrieving are merged. Can you guys help me on how to get the data into excel with individual columns?
I wish to modify a pre-existing procedure to import just the first four out of five columns from an Excel .xls file, which may be viewed as a "physical file" on the local hard drive.
I am creating a WorkSheet from code. I need my columns to word wrap and not run over (see red arrow below). Not really sure how to do it. Tried to set it for the range of columns with no luck. Here's the current output:
Here's where I try to set it: Protected Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click Dim xlApp As Excel.Application
I am trying to create a .Net application to edit a excel file by deleting some columns and keeping the columns which we need and then removing the duplicate values based on the first column which is going to be the Serial no. which should have a check to have 6 digits by default like 2563 should be displayed as 002563.
Code: Public Function GetAllFileContents(ByVal path As String, ByRef errorMessage As String) As IList(Of String) Dim contents = New List(Of String) Try Dim files = Directory.GetFiles(path, "*.xls") If (files.Length = 0) Then errorMessage = "Please select the files" For Each file In files [Code] .....
I am trying to create something different by not only letting me do it for excel files but for say txt and csv files along with it. Removing all the values which I dont want and removing the duplicates and then if possible putting a check on the first column of data that the serial number number should have minimum of 6 characters and then The output file should have all the details in Uppercase
I am reading XLS files, via JET provider, using the following Dim conString As String = "Provider=Microsoft.Jet.OleDb.4.0;data source=" + fileName + ";Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1;""" cn = New OleDbConnection(conString) cn.Open() da = New OleDbDataAdapter("SELECT * FROM [" & sheetname & "]", cn) da.Fill(dt)
The problem I am facing now is that some of these excel files have hidden columns: These columns are meant to be ignored. However, the code above fills my datatable with ALL columns (hidden and nothidden). Is there any "Extended Property" that I could add to the connection string, to ignore hidden columns?
I finally got this code to work after hours of toiling:

Now that I figured that out I was going to try and place the data in a specific location. On my application I have a datagridview set up with 4 columns. What I would like to do is put column A of the excel file under the 1st column of the datagridview and column C of the Excel File in the second column of the datagridview.
I fought through a good amount of this and have gotten to the point where I can sort my arrays. What I need to do now is take the following code and sort the elements in descending order instead of ascending order. I don't know how to do that with the two arguments in the code:
Dim Cols(3) As Int16 Cols(0) = ColumnNumber + 1 Cols(1) = ColumnNumber + 2 Cols(2) = ColumnNumber + 3
I'm using a reportviewer in VB.NET. When the user exports a report to Excel some of the columns get merged and hidden. is it possible to fix this? Maybe by manipulating some code or a setting somewhere..?
I have an integer array which contains the different col widths for an range of excel worksheet.when i use Range.ColumnWidth= ColWidths (Colwidths is the int array), it takes lot of time to do all the process (i.e opening excel , formatting range, setting values)But when i use Range.ColumnWidth = 15 then all the process is done in a flash.Why using an integer array takes time? I did even try replacing int array with string array, but same time taking result?
I'm trying to use VB .NET to parse through the column headers on an excel sheet, but I keep getting an exception when attempting to read cells. I'm thinking my syntax is wron
i am currently doing a checkboxlist that is retrieved from database. is there any way where i can sort the checklist items in a way like those checked itmes will be displayed at the back then those that are not checked will be moved to the top.
I am looking for the best way to dynamically arrange the location of labels (or any control for that matter) during runtime in a Windows Forms application using VB.net or C# in VS2008.I have a control that displays messages created by users.This control has a panel docked at the top which holds the header information for each message, called pnlHeader There are 8 labels: 4 of them display static descriptions (e.g. "To", "From", "Created Date", "Completed Date")And the other 4 display the relevant data for those descriptions. (Passed in during runtime from a MS SQL 2005 DB).Static labels are named: lblCreatedDateLbl and dynamic ones: lblCreatedDate The application runs on monitors of various size and resolution, therefor I would like for all of the labels to arrange themselves with equal spacing in pnlHeader, based on the current width of the panel.
At first, I had simply created the labels in the Designer and used Anchors (half of the lables were set to (Top, Left) and the other half to (Top, Right)). This solution worked for most scenarios, but did not always provide a consistent solution, so I decided to add the controls in code instead.
I thought it would be easier to work with the labels by creating a panel for each corresponding pair. So pnlCreatedDate would hold lblCreatedDateLbl and lblCreatedDate I wrote 2 methods: 1 to define each label and add it to the relevant panel: Sub AddLabels and another to determine the width of the panels and set the correct location: Sub SetLoc Currently, AddLabels runs in the constructor after InitializeComponent() and SetLoc is called after the data has been passed in from the database.
I've tried making minor changes and tweaks to the width and size parameters, enabling and disabling AutoSize, but nothing returns a consistent solution, instead either all the description labels are misplaced, or do not appear at all or completely whack locations come up.
Private Sub AddLabels() 'Label Created By:' lblCreatedByLbl.Location = New Point(0, 0)
I got a list of objects. Each object has a property called Z (integer).There will come a point during run-time I will want to re-arrange such objects in my list depending on their Z property. The objects with lower Z go first in the list, and the ones with higher will go last.I have thought of a couple things, like making a new List, then loop through each object in the original list as many times as the amount of objects such list has (so if it has 10 objects, I would loop 100 times), and each iteration will check the Z values. When a cycle is done (for every 10 iterations), I will remove the object with the lowest Z number in cycle and add it to the new List. And so on until the 100 iterations are done.
This is my first time posting in a forum like this, so please excuse me if I accidentally break any thread rules (btw, where can i find these?). I am very new to Visual Basic and have been trying to teach myself as I create this program. I have experience with macros in excel so I do understand some of the coding, but definitely nowhere near being proficient. I am using Visual Basic 2008 Step by Step (Michael Halvorson) to teach myself.
I am trying to create some code in my program that will allow the user to open an excel file and then return the number of rows and columns in the worksheet. There will only be 1 worksheet in the workbook (since this is just a small part of a larger program I am writing). I already tested the code that will open the file in another program and it worked fine; the thing that is catching me is the row and column counts. I'm a bit stuck here and was hoping someone could point me in the right direction. Here is the code as follows: Code: I have another sub for a quit button which I chose to leave out. The last line for the MessageBox is causing me problems.
Is it possible to retrieve the value of a cell from the row and column index of an Excel.Worksheet? I need to itearate through all the rows and columns and get the values.[code]
I am having a problem regarding to Importing file from excel to listview. Actually my problem is that my program will let the user define what database he/she want. I know already how to load on my listview from .txt, access, ms sqlserver, but my problem is the user want to open from excel file. Base from his data, the columns contained Contact, address, age,name and only in sheet1. My problem now is that the user want to call his/her excel act like a database. The tablename will be Sheet1 and if he/she want to display the age and name column he/she can view by calling the its columnname. The columname will act as a fieldname. How can I do this upon loading all of this to listview. I have here an example on how i load data from .txt(csv) format but i need an excel on how to load data coming from excel.[code]...
im usinf Gembox to read Excel files.I'm copying the fields to a datatable, so i have to add the columns to the datatable first. Therefor im using this code:
For i As Integer = 0 To objWorksheet.Columns.Count - 1 objDataTable.Columns.Add(i, GetType(ExcelCell)) Next
But objWorksheet.Columns.Count is 0 even if theres data in 4 columns.
I finally got this code to work: vb Dim path As String = OpenFileDialog1.FileName Dim myDataset As New DataSet() Dim strConn = New OleDbConnection("Provider=Microsoft.ACE.Oledb.12.0;Data Source=" & path & ";Extended Properties=""Excel 12.0;HDR=YES;IMEX=1""") Dim myData As New OleDb.OleDbDataAdapter("SELECT * FROM [Sheet1$]", strConn) myData.Fill(myDataset) DataGridView1.DataSource = myDataset.Tables(0).DefaultView
Now that I figured that out I was going to try and place the data in a specific location. On my application I have a datagridview set up with 4 columns. What I would like to do is put column A of the excel file under the 1st column of the datagridview and column C of the Excel File in the second column of the datagridview.
Obviously this doesnt work, and something tells me I might need a for loop to import the data, but I have never imported information from an Excel file before and to make it worse I have never worked with datagridviews before so I have no idea how to go about this.
I would like to do something like this if I could: vb For x = 1 To xldoc.rows.length - 1 DataGridView1.Item(0, x).Value = CType(xlDoc.Cells(0, x + 1), Excel.Range).Text Next

I'm working on a little program that uses a ListView box. I'd like to know if you can arrange the list by dragging the items within the ListView box. Example: I'd like to be able to just drag the bottom item to the top, or the middle item to the bottom, and so on. I guess I'm just wondering if I can move items around using the mouse by dragging them around within the ListView box.
Issue : Is there any efficient way to arrange many independent Windows Forms in .Net? I have to display many forms at the same time in my application. It is a graphic charting application, and the number of forms depends of what the user wants, so it has to be dynamic. Is it possible to arrange it like with MDI Layout ?
Example: For example, if user chooses 12 output chart forms, I would like to have them auto-arranged 4x3 on the default screen. Ideally, User could even choose many target screens among the monitors he has.
Why not use MDI: I do NOT want MDI, since my application is multi-screen and I want to leave the opportunity to the user to put his external output chart windows scattered over different screens wherever he wants. But I would though like to have a default arrangement of output windows, without calculating manually screen and forms width/heights by dividing and stuff (Already doing this, it's a real pain). I would like to spare myself this ant-work and focus on business logic.
What I am looking for: If somebody knows an open source library or tool or cool method that could be great. By the way, I found a very useful and handy tool that could help people having the same needs I am formulating here: It is named AquaSnap, but unfortunately code is not Open Source. PS: Again, I Know how to do it "by hand" and assign monitors to forms. It is not the kind of answers I am looking for.
I have these codes to load 2 MDI child forms from my menu...
