Opening Excel Files - Force It To Read As Text ?
Jun 11, 2010Application using ado.net
When reading data from an excel file the driver tries to detect the data type of a column based on the contents of that column.
Once it's decided on the datatype then data that is not compatible with that datatype is simply ignored and returned as Null when you read that column using ado.net
For example if most of the column contains numbers then the occasional cell containing non-numeric data is returned as null.
Is there a way to force it to always return all data as text no matter what the actual column contains. ?
Rich Text Box - Program That Will Read From Various Text Files (preferably RTF Files)
Apr 20, 2009Im designing a program that will read from various text files (preferably RTF files) and then put them into the RTF box in the program when a button is clicked.
Here is the portion of my code that i am referring to.
Try
Dim fileText As String = My.Computer.FileSystem.ReadAllText("c:\" & selectedHero & ".rtf")
infoDisplay.AppendText(fileText)
infoDisplay.Rtf.Format()
Catch
MsgBox("Selected Hero currently has no File with us.")
End Try
Now heres the problem. In the file i have a few pictures and its formatted and what not. I thought since its a RTF file and the Box is RTF it would auto format.... but anyways. It appears like this in the RTF Box.
{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fswiss\fcharset0 Arial;}}
{\*\generator Msftedit 5.41.15.1507;}\viewkind4\uc1\pard\f0\fs20{\object\objemb{\*\objclass Paint.Picture}\objw3000\objh3000{\*\objdata
[CODE]...
Ok so im not sure how i can read from a RTF file and put it in the RTF box with the right format....Ive been searching around for a while.
Opening Text Files When Listbox Item Is Selected
Aug 4, 2009a dialogue box to have the user open a file they wish. I'm trying to open a specific file when a listbox item is selected and I have that down but I'm running into the problem of needing to have "" in the display which is impossible from what I can tell in the code. I just need to know what goes in the quotes which will open the file. Also lets say the text file was 'supportdoc1.rtf' and was located in a folder inside of the program folder called 'SupportDocuments' would the path be "SupportDocumentssupportdoc1.rtf" [Code]

VS 2010 How To Read From Text Files
Mar 11, 2012I am making a recipe book that calculates the amounts of each ingredient needed for a dinner.The user inputs the number of people they are cooking for and then my program works out the amounts of ingredients needed, simply by * number of people.I know how to read from text files using commands such as: My.Computer.FileSystem.ReadAllText()But does anyone know how to take text for a text file, then multiply the contents of that file by the number of people?The text file only stores numbers, but I want to multiply each line seperately..Instead if getting the result of 10050*3, I want 100*3 and 50*3 on a seperate line.[code]For this to work, I suggest downloading the full project.You will also need to create a folder with two text files inside it. This will not work without them. "QuantityList.txt" and "IngredientList.txt".

Dec 21, 2010I'm completely new to .NET and am trying as a first step to write a text processing program. The task is simple: I have a list of 10,000 text files stored in one folder, and I'm trying to read each one, store it as a string variable, then run it through a series of functions, then save the final output to another folder. So far I can only manage to manually input the file path like this (in VB.NET):

I'm wondering, therefore, if there's a way to automate this process. Perhaps for example store all input file path into a text file then read each entry at a time, then save the final output into the save path, again listed in a text file.

I am currently using the 'StreamReader' function and 'InStr' command, but the files I am working with are gigantic and this is taking from 1/2 an hour to a few hours to work its way through.
Here is a sample of the code I am currently using - poke fun at will, I am a major newbie.

Do Until strContentsTime1_jntfor Is Nothing
strContentsTime1_jntfor = objFile1.ReadLine()
'look for string 'time'

Forms :: Opening Files - Allows Users To Select Picture Files And Then Categorize Them Into Folders
Jul 9, 2009I'm currently working on an application that allows users to select picture files and then categorize them into folders. Now I'm having two issues that are probably simple to fix but I only have a year of experience with vb so I just don't know how to fix them. The first and biggest issue is that once the user has selected and categorized a file, I want the program to select the next file in the folder that the first file was moved from. This way the number of clicks required is minimized. However I have no clue what I would need to do in order to accomplish this. Also, my other problem is that I want to be able to find the indexof a quotation mark but whenever I put it in the parameter it just reads it as a quote.
