How would one go about associating a file type with his application? I know how to read the command line arguments but I am not sure how I can "register" the file extension with Windows. Furthermore, my application is a stand-alone executable, so how would I keep Windows up-to-date on the location of my program?
I did a fair amount of searching and all I could find were old articles that didn't explain everything. How can I create file associations to a stand-alone executable in VB.NET?
I have a class IContact with various properties some of them being lists of other class objects. I have a public list of IContact. Can I write Contacts as List(Of IContact) to a file as opposed to a bunch of strings I then have to parse? I know visual studio has some data tools in the toolbox and a set of data classes, but I don't know how to use them or if they can help me write all this data to a single file.Second part of the question: I have associated .cms files with my program. But if a user opens the file, what code should the program run through in an attempt to deal with the file? This file is going to contain data that the program needs to read, how do I tell it to read a file when the program is opened vicariously because the file was opened?
I need to clarify these questions, I seem to have poor questions a lot of the time cause I don't get a lot of responses, and when I do get responses, they don't seem to answer my questions, I ask followup questions and then the thread will die after that usually..I seek not answers, but understanding, that I may not solve, but learn. What good is a fish without the skill to catch it?
I have an MDI Windows Forms application (.net 2008) that allows the user to associate various file types with the application. I currently do this with a registry entry something like this, that causes the application to load and access the file name via the command line:[code...]
In the pre-.net version of the application, I used DDE (ddeexec in the registry). If an instance of the application was executing when a file was double-clicked in Windows Explorer, it would open the file without starting up a new instance of the application.
Now that DDE has been deprecated by Microsoft, what is the best way in .net for an executing MDI application to open an additional file when the file is double-clicked in Explorer, as opposed to starting a new instance of the application?
I know there are allot of toppics about this subject, but i cannot find really what i need.
i need a file associations with settings.. so when you click for an example: "PC0210.config" it will start my program with some settings inside the "PC0210.config" File.
Lets say my program needs to give a message box with the PC name when you click the PC0210.config file.
that inside the PC0210.config file is something like: pcname="testPC"my program popsup with: testPC
Under Project Properties, Publish, Publish Options, File Associations, you can set what file associations your project uses. What should I set for ProgID?
I could find any results on file association. The only one that seemed to be straightforward was for a text file. I'm making a webbrowser. This is the code I was provided for a text file association:
Imports RegistryActions.FileAssociation Public Class HelloForm Private ftHello As New FileType(".Hello", "Hello", "Hello World Adjective File", "C:World.ico")
[code]....
How on earth do I make a file association for an html/htm file?
My name is Stefan and i would like to know how can my app see that it was started up on a file-associated DoubleClick?I know how to associate the files using the "Registry" method and the "Publish" method.

I am trying to create a file association in my program, which requires me to create some keys in the registry. However, when I try to create the keys, I get a System.UnauthorizedAccessException.
I have tried searching for a solution, and the only thing I can find is various examples of passing a boolean value to request write access for the "OpenSubKey" method. My problem currently is not opening the key, it's creating it. I have tried several of the different overloads to no avail.
I am guessing that I will need to temporarily elevate the access of my app to create the registry key. What I don't want to do is permanently raise the access of my app just to accomodate this one, small function, which should only really be needed by the user one time in order to create the file association.
Here is my code in progress:
Private Sub chkSOPAssociation_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles chkSOPAssociation.Click If chkSOPAssociation.Checked = True Then
[Code]....
I have a checkbox on my form. When the user clicks it, it sets the file association if the checkbox is checked, or else it deletes the association if the checkbox is unchecked.
I want to create a program in vb .net that let me know who is using a specific file? Because I often update an .exe file but if it's in use I can't overwrite it. So if I know who is using the .exe I can call him to tell him o close the app.
I was thinking about creating a program that creates an .exe file. (I know that that is very difficult but I have 3 days that I'm not sleeping because i'm thinkin about it)The program should create the .exe file on button clickThe created exe should be in Normal Windows State, it should have only a button that doesn't do anything and it's path should be C:UsersAdministratorDesktop

Its suppose to preview an inf file i create with the program

I have been searching on the internet but couldn't find anything that would help me. I want my program to be able to create a '.txt' file when it is run for the first time, with the date and time the program was accessed, and to be able to add new 'logs' of program history every time it is accessed. What i mean is that i want my program to be able to create a '.txt' file, and then fill in the dates and times when the program is opened.
I am woking on an application in which records of a table are stored in another table. In case of duplicate records they will not wriiten to the table and they should be written in a log file.
I'm trying to create a program which reads a text file into an array.
[Code]...
But that's just silly so how can I fix this? Lines isn't being assigned a null value it's being assigned the first line of text in the file which has text in it so I'm confused.
I want to have a single table that represents a person and have a number of other tables (such as Student/Teacher) use the Person table to store information related to a person. Unfortunately the entity framework doesn't seem to like it when I try to add an association between the Student or Teacher class and I don't understand why. The Person table contains a column called ParentEntityID, which equals either a StudentEntityID or a TeacherEntityID. In an ideal world I would like to be able to reference the Person table by going Student.Person.FirstName instead of Student.Entity.Person1.FirstName. The error .Net returns when trying to connect the Student/Teacher table to the Person table is:
Error 3007: Problem in Mapping Fragments starting at lines 265, 289: Non-Primary-Key column(s) [ParentEntityID] are being mapped in both fragments to different conceptual side properties - data inconsistency is possible because the corresponding conceptual side properties can be independently modified.
The actual database I am working with is a bit more complicated and has a number of tables connected to the Entity table, which makes my object model pretty ambiguous and was hoping to be able to clean it up a bit by using the entity framework.I am using VB.Net 3.5 in a web application.
Update...In an attempt to internalize the different types of relationships I can form, I have been playing with this simple example and have come up with the following possibilities:And the reason why I cannot make an association between the Student and Address table is because that relationship is not enforced in the database. If I wanted an association between these two tables I would need to re-think the design of my database. Is that correct?
I'm trying to create a "File Not Found" error to display if a file the program is looking for is not created.Example:
Dim ProcessProperties As New ProcessStartInfo ProcessProperties.FileName = "filename" ProcessProperties.WindowStyle = ProcessWindowStyle.Hidden[code].....
I also need help creating a text box, that will submit information to another source (like echoing to a command prompt window). I'm trying to add a killtask option where the user can enter the name of the tast (such as notepad.exe) and press 'Submit'. The button will then send a code (killtask -f notepad.exe) to a command prompt window.
