VS 2008 File Association And Opening Program From Save File
Jul 20, 2009
I'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.

I have an application that has a tabcontrol to handle multiple documents, just like Notepad++. And I also have file association working correctly with it.All I want to do is to make it open the double-clicked file onto a new "codetab" instead of creating a new instance of the program just to open a file.

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.

Ok, I'm trying to tackle this topic again. I have searched for setting file associations in the registry, and I only find references to adding the association the ClassesRoot, which, in Vista 64, throws an Access Denied exception.I would like to know if it is possible to set the association somewhere other than classesroot in the registry. Or, if it must be set in HKCR, then the proper way to temporarily elevate the application to perform the registry change.
What should happen is user clicks a button in my program to add the file associations, a Vista security dialog pops up prompting the user to confirm the operation or enter administrative username and password, user confirms, application sets the file associations, then drops back down to regular security.

Reading a .txt file in VB.net. My file path is C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt.
This is my line of Dim LoanOptionsFile As String = "C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt"
I can read the file when I run the program, but how do I write the file path so that someone else can download my program and file and read the file on their system?

I am writing a Windows Form program to automatically download and store generated PDF reports from a web site using the WebBrowser Control. The web site uses Ajax to link an icon back to the source aspx file which then returns a PDF file.
The problem I have is that the WebBrowser control brings up the File Save As dialog box when the PDF file is returned and I can find no way of handling this to cature and save the returned file. I have found other examples of how to manage this using the Navagating event to validate the extension of the file that is being accessed (e.g. [URL] and, if not an HTM, file then use the HTTP Web control to directly download the file. Unfortunately this will not work as the call references a .aspx page.

I need to be able to open a selected file (upon the user selecting it from his/her computer) in different browsers (CHROME, FIREFOX etc) I have downloaded the portable versions and placed and have figured out how to get them to open, but am not sure how to open the file selected in each seperate browser. is it possible to dictate the position and size of each window that opens? Because preferably I would like to be able to divide the screen up with each of the browsers selected.

How can I get a file to open in its default program by users, clicking on (Button 1 for eg.), a file dialog opening and then select a file and then it would open in the default program for that file type. I have tried other codes in these forums, but I get errors.

after downloading an emulator for the gameboy advance, all my icons hav turned to the adobe logo. When I double click on them, all that happens is the abobe reader comes up and says it can't open it. The only way I have found to open them is right clicking on them and hitting properties and clicking on shortcut ---> open file location and opening it from there.However I would like to open it regularly and I am not very computer savvy but I believe it has to due with file association.

I'm trying to use Adobe's command line parameters to launch a PDF file with a user's search term passed in automatically. Unfortunately, Adobe's syntax for this command requires me to start Acrobat.exe (or AcroRdr32.exe) and pass in parameters, including the PDF file name.I have users that might have any version of Adobe Acrobat from 5.0 up, or they might be using Adobe Reader version 5.0 and up. I know when I double-click a PDF file, Windows has an association with that file that points to wherever Acrobat.exe (etc...) is installed to launch the program. How can I get access to that information?I've looked in the registry at"HKEY_CLASSES_ROOT.pdf", but don't see much in there that would lead me to "c:Program FilesAdobeAcrobat 8.0Acrobat.exe" or wherever the program is installed. Does anyone know how I can access this information?

[ First off, this is not really a VB question -- it's a Windows 7 question, but when I posted it on a forum for Windows, a Windows "Support Engineer" suggested that I post it here. So here goes ... ]I have an old custom program (written in VB6) that opens a custom file type, but requires a qualifier in the command prior to the file name, similar to this:
myprogram.exe /i "myfile.seo"
The "/i" stands for "input file".
Back in Windows XP, I was able to make some very detailed changes to the file association for the ".SEO" file type, so that the "Open" action could contain this command:
myprogram.exe /i "%1"
The result was that I could click on any .SEO file and the filename would be substituted into the above command, in place of the %1. This did exactly what I needed.I have been unable to find a way to insert the command-qualifier "/i" into the file association in Windows 7.For a specific .SEO file, I can create a .BAT file, but that's a very limited 'solution'.

I have a very simple HTML reader for reading offline documents, and works very well when open using the menu. What do I need to do to get the reader to display the document I selected using by doing a double-click on the document name? The application will load, but the WebBrowser control stays blank. There's not a lot of code in the program so I will list it below.
Dim fName As String
Private Sub OpenToolStripMenu_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles OpenToolStripMenu.Click
OpenFileDialog1.Filter = "HTML Files|*.html"
OpenFileDialog1.FilterIndex = 1

Before I start, I'm not 100% sure this is the right place to ask. Okey, so I'm making my own Notepad, which will contain newer features. (Private use only though) One of them being tab control.
Now I want the program to be in the "Open With..." menus for all files, so I can choose myself.
And if the program is already running when user opens a new file, I want the text to appear in a new tab, instead of a new window of the program.
I tryed to be straight forward, and keep it short. So if you need more info, fell free to ask.

I have tried to do this before with a custom file type for a text editor. I barely got it to work... and now I can't even find those files. Now I just want for when I make my NSIS Setup that the file association can allow the mp3 player to play the files when the file itself is double clicked.

I am using Process.Start(fileName) to let Windows open certain files outside of my application with their 'default application'.If "fileName" for example is a ".txt" file, it opens the file in Notepad. If it is a folder, it opens windows explorer with that folder selected.This all seems to work well, except when the user enters a file that has no application 'linked' to it.(a file that has no file associations)I have wrapped the Process. Start() in a Try/Catch block so that any errors are caught and displayed.When I now open a file without any file associations (windows does not know with which application to open it) it tells me that it cannot find any application to open it with. (The exact error is in dutch so I don't think that's going to be much help here, but I think it's clear what's happening, no?)What I would like to happen in this case is that the windows "Open With" dialog comes up, asking the user to select an application to open the file with. Now it just displays the error message and continues, making it impossible for the user to open the file unless he browses to the file manually and sets up the file association, something many users probably don't know how to do.

I have this Quiz software that lets you create online multiple choice quizzes which are great for studying (I am in grad school and I'm trying to use everything I can to learn). So the Quiz software is great but it only lets you input questions by hand, one by one. I took a look at the .xml file that the quiz program spits out and came up with the idea to try and make a converter so that I can import many questions at once. I was hoping to try and solve this limitation by doing the following:
Take a .doc that say a tutor gives us with a bunch of practice questions, and then take that into Crimson Editor, and then format it so the question is on line 1, the multiple choice answers are on lines 3,4,5, and 6, (for the next question, the question would be on line 11, and the answers on lines 13, 14, 15, and 16, and so on) and then take that saved .txt file into my program, hit the generate button, and it will spit out the .xml file, and then import that into the quiz software to generate the online quiz.
Here is an attached screenshot of my program layout so far:
I figured out how to open a text file by watching simple youtube tutorials, but I don't know how to have it generate the stuff and have it show up in the bottom text box. I know how to do the coding to convert the txt to proper xml code but I don't know how to be able to save the contents of the bottom text window to an xml file.
