File I/O And Registry :: Exporting Information From A DataGrid To An Excel File Or CSV?

Jan 17, 2011

I am writing a program that uses several textboxes that a user will fill in and then click the add button to add the data into the datagrid. There is no backend database or anything. Just seeing the data in the program only.

What I want to do is then export this data from the datagrid into a file, preferably excel.

I've done copying textbox data into txt files but I can't find a method to copy datagrid data into a file.

Exporting An Excel File By Getting The Layout Of A HTML Page?

Nov 13, 2009

In my application I'm exporting an Excel file by getting the layout of a HTML page. So, in my codebehind, I'm modifying the HTML layout and inserting itens on it like if it was a webpage. Doing it that way, I don't need to use any external library and, as the data I'm exporting is just a table, I don't need nothing complex to handle it. My question is: there is a way to create an AutoFilter by just modifying the HTML tags? I mean, like if a put a < b>Column Name in the HTML, when exporting to Excel it will become Bold, it is possible to do the same thing with the AutoFilter?

Retrieve Information From A Binary File, Alter That Information, And Put It Back Into A New File?

Aug 27, 2009

I am using VB2005 and trying to put an application together.What it needs to do is retrieve information from a binary file, possibly alter that information, and put it back into a new file.The file is a .wav file with data appened to the end. There is an additional section at the end of the .wav file which stores xml data.I have found that if I open this in a hex editor and make a 1:1 swap on any of the bytes that the application that the file is for can still read the XML.If I tried to add or remove characters from the XML then it would not read. I located a header byte and incremented it to resolve this.

This worked as an excellent bandage to do conversions where the data always needed to be changed to the same thing.What I have been asked to do is build logic that allows for different things to happen depending upon what data is contained within the file.The method that I am currently trying to impliment is:

Read through the file with a system.io.binaryreader

Searche for a bytestream that will signal data is coming

For example:

If System.IO.File.Exists("C: est estread.wav") Then
Dim findit() As Integer = New Integer() {&H3C, &H55, &H73, &H72, &H44, &H65, &H66, &H30, &H31, &H30}
Dim i As Integer[code].....

And then extract all the data till the end of element marker "<" It seemed like there should be a better way and I was looking for some insight. If I proceed with this method, I will have to read the file one time to gather the information and then a second time to write it all out with the header modified for length.This is my first experiene with working with binary files in this way.Also,I've been experiementing with building a string and slapping it back in at the end using the binarywriter.write(string) method.I noticed that it was putting in header characters before the string.These seem to change if I change the length of the string.At one point it was d0 07. Later it became e7 07. Does anyone know of a way to prevent this header from being inserted?

I tried a for each loop to grab all of the characters from the string, convert them to a byte array and deposit the byte array into the file, but the header remained the same. When I write the byte array generated from a system.io.binaryreader I do not get this header.

Using Which Exports A Datagrid View To An Excel File

Apr 17, 2009

I have some code that i am using which exports a datagrid view to an excel file. It works, I am trying to either delete or clear a series of unused columns at the ens of the sheet, there are 9 columns. I am using the following loop to rid the columns and i am getting Exception from HRESULT: 0x800A01A8.

I did some research and it seems to do with late binding, code that is giving me the exception follows:

Dim ZZ As String = "J"Dim AJ As Excel.Range = CType(wSheet.Columns("A" & ZZ), Range)
With AJ
For g = 1 To 9
.Select()
.ClearContents()

[Code]...

I read on msdn if AJ in this case starts out as nothing then vb will throw this exception and to use early binding. I cant bind a column if it hasn't been created yet, so i played around with the placement of the declaration of AJ to no avail, what is the right Direction i should take to fix this issue?

User Selects An Excel File And The Contents Are Loaded Into A DataGrid?

Dec 20, 2011

I'm in the process of adapting a current program that I've created to automate it. **Current State***User selects an excel file and the contents are loaded into a DataGrid User can select which environment to run their query against (stage/prod) Program completes processing and updates datagrid with new values User can export datagrid to excel What I'd like to do is centralize the program on one computer and have it monitor a network folder for creation of a specific file type (*.xls or *.xlsx). If one of these is created in that folder then I want to add that file to a queue for processing. Once done processing I want to send the results as an attachment to an email to the user that created the file. After a file is processed I would like to remove it from that folder as well (into a diff folder of completed items).

File I/O And Registry :: Binary File Primer - Read The Nth Record Without Reading The Whole File?

May 4, 2009

I need to write data to a file, preferably in binary format, but I am unaccustomed with the concept. Where's the easiest place to get the basics? I could come here with a specific need, but I'm at the point right now where I am more willing to work within the confines of keeping it simple.

Here's what I know:
1. how to open a new file
2. how to specify the record length
3. how to close the file

Some specific questions:

Does the record length have to be constant throughout the file?

Can I read the nth record without reading the whole file?

File I/O And Registry :: File System Object Does Not Allow Spaces In File Names

Feb 3, 2010

I am working on a VB Console Application that takes an Autocad drawing type DWG and converts it to a PDF using a shell command that calls a third party application. In this case, acmecadconverter.exe from www.dwgtool.com. Then the PDF that is created needs a unique watermark, so I call a second application for that called pdftk.exe from www.accesspdf.com/pdftk/.

Everything works as intended, except when I try file names that contain spaces. The file system object does not tolerate spaces in the drawing file name. For instance, the following command gives me a system.io.filenotfoundexception...

My.Computer.FileSystem.RenameFile("Test Flowchart1.dwg", "Test~Flowchart1.dwg")

It's the same problem for all of my File System commands. Either file not found or invalid arguments.

The complete script I'm using is here:

Code:
Sub Main()
Dim arrArgs() As String = Command.Split(","), _
i As Integer, folderPath As String, myPart As String, _
