I'm trying to open a .chm file in my VB solution using the following
Dim binWriter = New IO.BinaryWriter(IO.File.Create("help.chm"))
binWriter.Write(My.Resources.MyHelp)
binWriter.Close()
Process.Start("help.chm")
Everything works fine but when I click twice on the command button to open the chm I get the following exception:The process cannot access the file 'C:help.chm' because it is being used by another process.
What i am trying to do is open a save file dialog and write to a .txt firl the contents of my listview. so far:

I understand how to associate my windows form application with a file extension (in my case, *.cmf). However, when the user double clicks on the file in, say Windows Explorer, the application opens but without the file being loaded. I also understand that this scripting (for the response to double clicking the file) can be defined by the My.Application.Startup Event, but I have not been able to find (in either this forum or MSDN) a clear example of what to do with the command line arguments after they passed to the application

I have an app that works client cases and at one point they need to open a .MSG file that's been dragged into the case.
Right now it opens in Outlook. Sloppy and slow.
I would actually like to open and parse the data out of that file myself. Maybe put it into a richtextbox?
I want to put the program in a folder before I send it out, And it has several .txt files in the folder such as "How to use this" and "how to use that" I have a menustrip, And I have an option "How to use." < Whatever section there on.How would I make it so when they click that it will open up a .txt file from that folder which would be like" My program By ME " would be the folder name..I was thinking streamwriter or streamreader? But I can't understand how to use it.
View 13 RepliesOn my computer I've set that when you try to open a txt file it opens it with my application. When I open a txt-file, the computer opens my program, but then is RichTextBox1 empty. (Of course, because I haven't set my program yet to show the content of the textfile in RichtextBox1.)
How do I make my program know from which file it's launched? So that it can load the content of the file using a StreamReader?
Can someone point me in the right direction? I am trying to find out the 5 modes a file can be opened in.
I can only think of Input, Read and Shared. What are the other two?
I want to find the full path of the program that will open a given file type. e.g. '.txt' is opened by c:windowssystem32 otepad.exe
I've done a bit of searching but i keep just finding how to create an association, not read one. I've also tried looking in the registery, but it looks like all that's there is a link to the program ID or something.
How would I be able to click on a label and make a text file open which would be save in the folder i sent out so something like
C:UserDesktopProgram FileRead me.txt
How would I also do the "user" part since I wont know everyone's computer user name that I send it to?
ok if there is any way to open a file from zip archive without extracting it ?

My intention is to open an image file as bytes, Convert the bytes to a string, send bytes to server and server stores bytes in a database. Then I need to reverse the process and be able to convert the bytes to an image.

View 12 RepliesI'm making a tiny program that calculates a total for a user for some type of styling service. A user clicks the radio button for either hairstyle, perm makeup, makeover, or manicure. then clicks a discount radio button, either none, 10% or 20%. then it calculates the total (price of service - discount %). then it displays the total in the current service text box & keeps a running total and displays that in a second total box.
My problem is i try to run the program i made and it basically crashes. In the code, when in VB, there's an error message when you go over PriceDecimal, DiscountDecimal, and GrandTotalDecimal saying the variable is used before it is assigned a value.also is there any way to open a .exe file and see the code for it?
Public Class ImageForm

Const MAKEOVER_PRICE_Decimal As Decimal = 125D

I'm trying to open any file using Process.Start, but every time I try to open a file that isn't an executable the program crashes... This is the code I'm currently using:
vb.net
Private Sub ListView1_MouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListView1.MouseDoubleClick
For Each lvi As ListViewItem In ListView1.SelectedItems
Process.Start(path & "" & lvi.Text)
Next
End Sub
Path is a string that contains the selected folder path, and lvi is the text of the list view item (each item contains the icon and name of each file). It is working fine for .exe files, I was just wondering if it's JUST for .exe files...

I have created an Excel AddIn that has a custom ribbon with some custom buttons...I'm using Excel 2010. One of the buttons is to save the the workbook by utilizing the users input as the file name. This workbook is to be saved as a template in a specified folder. The code also checks to see if the file already exists, and prompts the user to overwrite if it does already exist.The code I have seems to be working just fine. The problem is...when I try to open the newly saved workbook, it won't open.Here is the entire code for the button click event:
