I'm a relative newcomer to VB.NET so please forgive any lack of knowledge.
I'm writing a web application that lists the contents of a directory in a listbox and then (in theory) opes the file that the user clicks on.
What I'd like to do is open the listed file in it's associated application (so if it's an excel file, open excel; if it's a notepad file, open notepad).[code]...
After I ran a disk-cleanup (in my case AVG PC-TuneUp), the loading of my VB.net project gave error on a missing file.Changing the build-configuration (DEBUG->RELEASE->DEBUG) would recreate the file and all is OK. But I have basic configuration-info for the build, maybe in more complex cases some important details could be lost when the file gets deleted.I would think an information as critical as that, would be placed in the project folder, or be part of one of the many files that make up the project, but not in the temp-folder.
View 7 RepliesHi, I need to program a simple Web Browser that can search for keywords and store relevant data in another file.I am facing a problem with authentication, mainly cookies and maintaining a session.So I read that Web Browser Control is based on I.E.? So may I know how are cookies and session handled?Do I have to implement them manually or are they stored and retrieved from the same folder as the one used in I.E? If so, if I delete the I.E.'s cache, am I also deleteing the cache of any Web Browser I make using Web Browser Control?

View 19 RepliesI have referenced this thread and the website it points to:pening a file in my application from File ExplorerAs of now, I can't get My.Application.CommandLineArgs to work properly. Any time I select an file to open in my program I get a windows error forcing the program to close. I only want to get the file path from My.Application.CommandLineArgs and pass it to a function that will then parse the file (a text file of various extensions, even if it is not associated with my program) and display the contents in a RichTextBox.My function to open the file is complete and works, but if I try to use My.Application.CommandLineArgs on a file the program crashes immediately.here is the code I'm trying as a test:
Private Sub ParseCommandLineArgs()
If My.Application.CommandLineArgs.Count > 0 Then
MessageBox.Show(My.Application.CommandLineArgs(0))

I have a program I made in vb.net express 2008 that used java.utils.zip to compress my work files to a Zip archive that I ran occassionaly to have a backup. I worked fine, but with net framework 4 and vb.net 2010 it doesn't work. So I modified it to use sharpziplib and it works fine if all files on the filter list in the folder are closed, but if I have a file open in OpenOffice writer, my program can't access it and won't create the zip file. The file that usually stays open all the time is my TODO list, that is updated several times a day , so usually gets printed, and updated( adding or deleting entries), without closing it.

I understand the Diagnostics.Process.Start but for some reason its not referring to my xsl file its just loading all the values in order. My question to yall is how do i set a path inside my application for the xsl and xml to refer to each other.

View 16 RepliesI created a VS2010 application that stores data in xml files with a custom extension (e.g. ".ABC") I would like to be able to open an .ABC file and have the application launch with the specific file's data loaded. This is analogous to opening a Word doc and having Word open with the doc loaded. I have searched for a while but can't even think of a phrase that explains this process. Nothing seems to match "You know . . . that thing that happens when you double click on a data file".

View 1 RepliesI am trying to write a code to save and open data that is in my application. My application contains hundreds of text boxes, combo boxes and labels. I have created an array for each set of data, i.e.,
glist(0).store=combobox1.value
glist(0).cat=combobox2.value
glist(0).it=label3.text
glist(0).quan=label4.text
glist(0).total=label5.text
up to glist(89).
Is there a way to write a code to loop through the array and save the values so that they can be opened at a later time in my application? The array will contain Doubles and Strings.

I am writing a small visual basic application to install clean up tools quickly on any machines that we need to work on here at my workplace. I am using 4-5 cleanup programs that I have packaged into MSI's and have batch scripts that I am calling in my visual basic application to run them as silent installs. However, because I am doing the silent installs, windows always pops up with the "open file - security warning" and I have to click run for each individual program. I am wondering how to get around this from my end within the application. I know it can be disabled in windows but I am not wanting to have to go through a process on every machine that I run this program on. I would like to find a fix on the back end in my script.
View 2 RepliesThis is probably a pretty novice design question. I'm trying to work my way through a number of requirements and give the users the experience they're looking for.I've written a tool that does big calcluation-type things. It currently consists of a class library and command line tool (separate .NET projects.) We're using an Access database format as the file type because it can keep all the various tables together in one file. A few other items about the application: There are not many users. There are no concerns with scalability. There are not great concerns with updates. Desktop is desired. Not web.Using VB and .NET 3.5 SP1
I now need to develop a GUI front end that will allow typical File/Open and File/Save type operations.Users expect that they can open a file, edit it some, then either choose to save it or close it unsaved without any changes being written back to the file. Saving it would obviously save all changes affecting all tables back to the file.
Does it then make sense to use a temp file for something like a proxy then? To, when a user "opens" a file, copy the source Access file to a local temp file and then use that for the editing session? Then, if the user "saves", copy the local temp file back to the source path?
Update: [tagged with ms-access tag too] Also, I omitted the fact that users would expect typical File / Save As functionality too. I think the design I've put in question in this post is what is traditionally called the Proxy design pattern. Has anyone tried this (successfully!) with Access database files before? Words of caution or advice?
I have a project that is used as management for a YouthFootball Team. Part of this is adding training fees and keeping track of who has, and has not paid.This part of the project is adding the fees to the relevant textfile.Textfile - Trainingfees.txt
Each line looks like - player name|number of sessions attended|amount paid I have a form with a DataGridView. Each row is populated with: Checkbox Column, Player name in textbox column, blank textbox coloumn The user then ticks who attended the training and how much money they paid in that session.
I then have this code to loop through the DataGridview and add call a separate function that adds the relevant information to textfiles.
