VS 2005 Opening And Saving Text Files Error

Jun 11, 2009

A query concerning opening and saving a file.i have two commands, one the opens and another that saves [the same file].i'm using the StreamReader and StreamWriter methods.issue is this:if i comment out the open code, the save works fine.if i comment out the save code, the open works fine.if i let both run together, i get an error, usually with the save saying that the file could not be accessed. note, before anyone asks, i do close the file after saving or opening what could be the problem? open works fine, because it usually happens prior to the save, and then save process cannot access the file..?

VS 2010 Opening And Saving .txt Files?

Sep 1, 2010

First time user on here, basically have been teaching myself VB and I enjoy it quite a bit! Basically I have a program now that has the File Drop-Down Menu with Open and Save options. I want to open and save in a .txt format. The open command will need to place the text in TextBox1 ; and the Save command will need to take the text from TextBox2 and save it as a .txt. I have gotten to the point where it will save it to a specified .txt file, but I would like the user to be able to "browse" the computer for where to open from and save files to.

Excel 2007 Macro - Runtime Error 1004 After Saving And Re-opening A File

Oct 25, 2009

I have an Excel file with utilizes macros to allow a user to enter names of people and then double click on cells to enter ratings via radio buttons. When I open a blank file and enable the macros, I can add users, rate their skills using the radio buttons, etc. with no issue. I then SaveAs the file and continue working on it. once I Save and CLOSE the file, then go to re-open it, the trouble begins. Keep in mind, there is no alteration to the macros directly. Just entering data and using the form as intended. Here's what happens.

I reopen the file.I enter in the name of a person on one line. I go to the first box - double click on it.It is supposed to pop up a dialog box which allows me to choose a rating via radio button (as I had been doing before I closed the file). Instead, in that first column of ratings, it instead gives me the following error:

Runtime error '1004'Unable to set the LineStyle property of the Border class

When I hit "debug" this is the code it points to:

If ActiveCell.Column = leftb Then Range(Cells(ActiveCell.Row, leftb), Cells(ActiveCell.Row, rightb + 1)).Borders(xlEdgeTop).LineStyle = xlContinuous I have no idea why this would not work when I re-open the file!

note that when I go to click on the subsequent cells (there are 8 cells in which you provide ratings, moving across the columns with each cell) - the 2nd through 8th cells function fine. The dialog box pops up, the rating can be selected. it's just the FIRST cell that gives the issue What would possibly be the cause of this? We need users of this form to be able to save, close, and re-open it if needed.

Opening Excel Files - Force It To Read As Text ?

Jun 11, 2010

Application 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. ?

Saving Text Files On Vista?

Sep 9, 2009

I'm having some problems with people saving text files using my program, but only people using Vista. Since I don't use Vista myself, I'm not sure what this is but it's not a problem on any machine running XP.

Note that my file saves just using the standard Savedialog box and Filestream/Writeline commands.

From what my customers are telling me, the save dialog comes up fine and there is no error as the file appears to save, but when they look for the completed text file, there's nothing there.

VS 2005 Saving Battery Level Variable To Text File?

Jul 28, 2010

Currently, I've encountered a problem where I do not how I can store the variable of my battery level in a text file. I tried .xml and .txt file and it returns me text which can't be read.The code related:

vb.net
[code]Dim psBattery As PowerStatus = SystemInformation.PowerStatus
Dim perFull As Single = psBattery.BatteryLifePercent

[code]....

The place where I do not know what to insert is the "Insert Battery Percentage Here" part so I guess that's the problem.For your info, if you were to use a MsgBox to display, the code which displays that would be <MsgBox("Total battery power remaining: " & perFull * 100 & "%")>

Forms :: Opening Files - Allows Users To Select Picture Files And Then Categorize Them Into Folders

Jul 9, 2009

I'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.

Automating Process Of Opening MPP File And Saving It As CSV?

Mar 12, 2012

I need to find a way to automate the process when a user uploads a microsoft project file to a web application I already have created. The process will need to basically use the save as from project to save into a .csv file so I can use this to import the data to an SQL database (this is needed for custom reporting we already have set up using SQL). I need to automate this process because I will be receiving tons of project files, and if the process is automated the users will then be able to instantly see results.

Basically, is there any way to create or run an automated process that will save these project files as .csv files? Even if the csv files are not formatted correctly, I can find a way around that, just need to first get them into .csv files. The only way I could think of this is to follow the instructions listed below, but I would then need to automate a process to open the file and hit save so this works... [URL]

VS 2005 Importing Delimited Text Files To Excel With .NET

Nov 11, 2009

I need to dump a bunch of delimited data to Excel. In VB6 days, I would save the data to a text file, then use ExcelApp.ActiveSheet.QueryTables.Add (blah blah blah...) to import the data to Excel (I got this code from recording a macro while manually importing a text file).In VB.NET (2005), QueryTables does not appear to be an option for ActiveSheet.I could take the long path and manually parse thru the data writing to individual cells - however if I could just import it, it would be much faster.Part of the issue is not being able to record a macro in Excel in .NET format.So my primary question is, how do I import a delimited text file in to Excel without having to manually parse the data into individual cells.Secondary question is any tips for not being able to have ready made examples (in VB .NET format) by recording a macro.

Mvc - Saving Files And Names To Database Table Using For Each On Request.files

Mar 9, 2012

I have multiple file upload boxes on a form in my mvc3 application. Request.Files shows 3 files when I put a break point in the below function and look at it.. Problem is other than coding a counter and using a select case I dont see a way to handle saving each file name to the database column it belongs to... Is there away to assign the variable on the fly I guess you could say So that the foreach loop would drop the file in the correct column. Ie handoutFile1, handoutFile2 , handoutFile3, Etc. As it stands the below will overwrite the filename in handoutfile1 every time the loop is gone through. I thought about throwing a counter in the loop and just put a select case on it to assign the db column based on the counter number. Seems like a cheap work around though. [Code]
