How do I open up the files displayed in the Listbox with an external text app.
I coded this :
Imports System
Imports System.IO
Imports System.Collections
Public Class RinexHeader
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

I have a little GUI setup with a Listbox and a Richtextbox.I want the Listbox to display all of the .txt files displayed within a folder I have defined, then when a ListBox item is selexted, it displays the contents of that file within the RTB.

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]

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.
View 4 RepliesI was working with a calculator i made.. and then i was thinking of making all my calculations to be displayed in the listbox..Here is my program for the calculator..

I'm having a problem with my software.
This is are the parts of my system where my problem occurs:
- Search Button
- List Box1
- TotalTextbox
- Button
- SQL Database with a Column named "Amount" and it only contains numbers Datatype is System.String
So, basically a user clicks the Search button and searches for a data in the SQL Database, and the result of the search displays in different Listboxes including the "Amount" Column from the database, which has it's own Listbox named "Listbox1". the Listbox is now filled with numbers.
Goal: The goal is to get the Sum of all the "Numbers" Displayed in the Listbox1, and the Total is then Displayed into a Textbox via using Click event or automatically.
The Code:
Dim sum As Double
For x As Integer = 0 To ListBox1.Items.Count - 1
sum += CDbl(ListBox1.Items(x))
Next
TotalTextBox.Text = sum.ToString
And i got this Error: Conversion from type 'DataRowView' to type 'Double' is not valid.
I ended up with this..
Dim sum As Double
For x As Integer = 0 To ListBox1.Items.Count - 1
sum += Val(ListBox1.Items.Item(x).ToString)
Next
TotalTextBox.Text = sum.ToString
But the values are not adding up, the total is always at 0. i've been searching for hours now from the net to a better way of doing this.
Here's a quick Flow on what im trying to accomplish here. Record from Database -----Displays on---> Listbox1 -----User Clicks--> Button1 ----Displays Total sum on----> Textbox1

View 3 RepliesMy knowledge of VB.net is limited (only have been reading from the book)
so what i need to do for my project is to populate a listbox with files from a certain directory (C:folder)
then once it's populated, i can select an item and it will open up in a rich text box.
This is what i have so far for the active directory > list box:
Dim di As New IO.DirectoryInfo("C:Documents and SettingsuserDesktopfolder")
Dim diar1 As IO.FileInfo() = di.GetFiles()
Dim dra As IO.FileInfo

Ok so what i want to do is using openfiledialog3, the user opens a file (that is MP3) it then loads into listbox1 (the listbox is in FileInfo format)

View 3 RepliesI have 19 .CSV files that hold engineering data in single and multiple Arrays.I would like to loop through the Directory that contains the files and open each file, fill the array and close the file and continue to the next in Alphabetical order.
This code tells me how many files I have now and will update if I add more.
Dim FolderPath As String = IO.Path.Combine(Application.StartupPath, "DATACSV Files")
Dim TestFolder As New IO.DirectoryInfo(FolderPath)
Dim FileCount As Integer = TestFolder.GetFiles().Count
FileCount give me my number of files but not sure how to continue. I have the code to open and read the file but not how to keep changing the file name for each new file name base on the number of files that exist.

View 6 RepliesI am having problems with copying from one listbox to another and keeping the paths of the files in the listbox's. At the moment i have two listbox's, listbox1 shows the list of files without the directory paths showing. Listbox2 is used to add items from listbox1 which work ok but what i need is to be able to preserve the directory paths to each file. how to do this and have searched high and low for a solution without any luck.
I have worked out one way of doing it but i think there is a better way of doing it as the reverse does not seem to work. So basicly i want listbox1 to list the files without the paths and pass it on to listbox2 so that the files can be copied to temp directory as they are being add to listbox2.
Below is my

Am writing a simple application which can write a to pdf,doc,xls and access files. so far it can write to word.i also want it to be able to navigate a hard disk and open these files using filters. i was using this code to write to the files
[Code]...
I am writing a program that stores filenames, along with a lot of information about the files in a database. I need to be able to open these files in three different programs from my application. One of these programs, AutoCAD is the default program for the files, but the other two are more difficult. These two need to open the file in a program that is not the default for the file type. Eventually, I'd also like to allow users to point the application to the instance of AutoCAD, MasterWorks, or FeatureCAM that they want to open. I have found articles that explain how to open a file in a default application and articles that tell me how to open any application with a file name, but only 1 suggestion of how to control the program used to open the file. For some reason I cannot get AutoCAD to recognize the file I feed in if I use this method though, so I think it's wrong. This is the method I found that doesn't work:
Start("D:Program Files (x86)AutoCAD 2007acad.exe", file)file is a variable that contains my file name. Since this works fine when I take the program path out, I know the filename is correct, but AutoCAD says it is not.
A simple WebKitBrowser1.Navigate(localfilehere) doesn't work for some reason.
I tried adding "file://" to the URL but that didn't work either.
This seems ridiculous but is this functionality really not present?
I am programming using VB-2005 on a Vista Based machine. I am trying programmatically to open a PDF file that is Password Protected. I have worked out the steps required to open a non-protected PDF. Adobe tells me that it is not possible to pass a password to the PDF using the objects that come with the PDF Control. My question is can this be done in some other way, e.g. with WinExist etc.? Is WinExist and other such commands even available in Visual Basic?

View 1 RepliesOk hard to explain this one, it may be the codeproject addin i added recently or its a setting i have changed somewhere but when i'm debugging my app opens up many .cs files, kind of interesting but when i want to step through my code it goes into these files and when it errors it has no reference to where the error actually is. sometimes these files being opened have errors on them which i have had to correct for the code to work.
Has anyone seen this before and what could i do to stop it, i wish to confirm that it is this addon before i remove it (which i will do if it is this addon causing this).
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.
