Error When Opening Text File - FileNotFoundException Was Unhandled - Could Not Find File At Xxx
Feb 15, 2012I have a program that can save user's input into a text file and load it back, but whenever I try to open the file and exit without selecting the file I get an error.(if i select the file and open it i don't get any errors).
This is the code that handles text file loading:
Private Sub Button4_Click(sender As System.Object, e As System.EventArgs) Handles Button4.Click
OpenFileDialog1.InitialDirectory = "C:"
OpenFileDialog1.Filter = "Text Files ONLY (*.txt) | *.txt"
OpenFileDialog1.ShowDialog()
[CODE]...
The error is :"FileNotFoundException was unhandled. Could not find file at xxx". also I would like to know how to make it so that the initial file name for file saving is today's date. I do not get any errors when I try to save the file.

View 9 RepliesVS 2008 File Association And Opening Program From Save File
Jul 20, 2009I'm having a slight problem getting my program to load a save file when double clicking the save file.I'm using the Command$() to get the command line argument. I can open a save file by dragging it onto the exe. But not by double clicking the save file (after it's associated with the exe).I though dragging and dropping a file on a program and double clicking the file would open it in the same way, but I guess not.So in short how does file association work and how do I get the file path set to a var when the program loads.

File I/O And Registry :: Text File Reading And Writing?

The problem I have is that I wish to open and save text files to and from arrays in the background. I've attached what I would do in VB5.

Writing Array Of File Names To Text File
Mar 11, 2010I am attempting to gather a group of file names from a directory. I am able to do this. I tested the code by having the list populate into a listbox and all desired items were added to the list.
Here is my code:
Dim di As New IO.DirectoryInfo(strPath)
Dim dir1 As IO.FileInfo() = di.GetFiles("*.txt")
Dim dFiles As IO.FileInfo
ListBox.Items.Add(dFiles)
However, a listbox is not my desired output. I am attempting to write these file names to a text file for purposes of then parsing the information to a datatable to compare with another datatable. How to get my filenames written to a textfile.
File I/O And Registry :: Timers And File Opening?
Nov 11, 2008I am using VB.net 2005 and I have a timer running on form1 that communicates modbus with a relay io board. There should be constant uninterrupted communication between the two devices and that is working until I open the data logging form2 and import data from a large sequential text file. While I am parsing data, the timer from form1 stops communicating with the modbus device. Once the data is done, the timer of form1 resumes communication with the modbus device. Is there some other method I could use to make sure the modbus communication is never interrupted.? Is there a command I can periodically run from form2 while the data is being parsed that will keep the timer on form1running?
View 2 RepliesWriting File/Folder Sync Prog, Result Text Boxes Not Updating Untill After All File Action Is Done Even Though Update Code Comes Before Copy?
Apr 12, 2011I am working on a program using VB.Net 2010 which will enable me to setup groups of files & folders for back up with syncing capabilities etc. I have a concept program which is based on some sample code I found out in one of the VB.Net forums. I have modified it from a command line based program to a form based program. At the moment I consider this code to be a "concept" program which once I have the various copy/sync routines developed and debugged will be integrated in to another program I wrote for
creating "Back Up" groups to automate the process. There are some 3rd party programs that do similar things that I want to do such as Microsofts Sync Toy, but none of them offer the grouping and exclusions options that I am going to program in to this backup/sync program.
So here is my problem, I have the included code taking two folders, a source and a destination, and copying everything from the source to the destination. It will skip over any unchanged files/folders and will delete anything found in the destination folder that is not found in the source folder and it will update all files in the destination folder that have a newer version in the source folder. In other words it will mirror image the source to the destination but will be smart enough not to copy unchanged items from the source to the destination thereby saving a lot of time. The sync part of the program is working fine, the displaying of the progress and results is not.

View 2 RepliesIE6 Opening XLSX File As An XLS?
Jul 14, 2010My application generates XLSX files based on a users requirements.
After the XLSX file is generated the user is redirected to where the file is saved using Response.Redirect...
Response.Redirect("filename.xlsx")
When the user then opens the file... they recieve this message.
The file you are trying to open, 'filename.xls', is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?
As a temporary fix I've instructed my users to press "Yes" when they receive this message and the file opens perfectly fine.
Does anyone have any ideas why IE6 is trying to open an XLSX file as an XLS?
Opening A File As Administrator?
Aug 21, 2009I am developing an Excel workbook at work and I've got a problem. I'd like to save information entered in the workbook and save it in another one (called List, for example purposes), using a macro. The problem is that the file in which I want to save the information is located on a server. When people open List.xls, it's Read Only. So, when my macro executes, it opens a Read Only workbook...I'd like to do "Open As", just like you could do by right-clicking on any file in Windows XP. The result would be that the macro would log on as administrator only to open List.xls, write in it and save it under the same name.
