I have a tab-based application that handles multiple documents. It is designed such that the user cannot run multiple instances of application. Furthermore, the user can double-click on a document file, and the application will launch itself and open it.[code]...
View 9 RepliesBefore 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 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.
View 8 RepliesI 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.
View 2 RepliesI 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.
View 19 RepliesI have an application that can read certain types of files, and I have it working so that if you do "open with" from windows, it automatically starts the application and opens the selected file.
Unfortnately, I cannot get it to work for more than one file.
System.Environment.GetCommandLineArgs() contrains the following:
System.Environment.GetCommandLineArgs(0) = name and path to the .exe
System.Environment.GetCommandLineArgs(1) = name and path to the first file selected to be opened
System.Environment.GetCommandLineArgs().Length is 2 when the user tries to open 1 file, which makes sense since the first argument is the .exe itself and the 2nd is the path to the file, but it does not increase to 3 if the user tries to open 2 files... meaning that System.Environment.GetCommandLineArgs(2) is never populated Here is some sample code that shows the problem: It will recognize no files or 1 file being opened, but if you try to open multiple it will only show the first.

I'm using this code to load multiple files using windows context menu, but the problem is that the aplication is open many times as files the user has selected.For example: If I select 14 files, an open them with the application, the aplicacion is opened 14 times and load the form only one. But there is a way to send all arguments once? Because %1 send only one file, or there is for example a %2 that send all file pats in one argument? If there is I'vent found.
This my actual code:

When I select multiple paths from openFileDialog in my listBox control enter only one path by try. This is probably because that I use OpenFileDialog.FileName. I wish to load all selected files in one time...but in this case Add(OpenFileDialog.FileNames) give me the value stringArray in same listBox. I suppose that maybe exict peace of code through ItemCollection which give me opportunity that I import all file path in one try in listBox control. It was interesting because how I may implementing matrix between openFileDialog and listBox..
View 4 RepliesI have a program that works when, a file is opened with it using the right click menu in explorer. But if I select multiple files and then right click and open with my program then it opens multiple instances of my program, instead of just passing the multiple files as arguments to a single instance. The program is written in vb.net but is not a windows form, it is just a module, so I can to tick the Single instance option in the properties in Visual Studio.So how do I open multiple files from explorer context menu in a single instance.

I'm creating a kind of 'playlist manager' application where the user can create his own music playlist and then play it from my application. However, I don't want to give my application any playback features itself, as there are already so many media players around. Instead, I just want to open the files in the current playlist in the media player of the user's choice.
I have a list of MP3 files (their filenames), how do I now open these files simultaneously in, for example, Windows Media Player? I can get it to play one song, using this command (and Process.Start)
[Code]...
Surely this must be possible? You can open multiple files in windows itself simply by selecting them and opening them at the same time. I'm pretty sure the filenames of the selected files will then be in the arguments of wmplayer so that it can open them, but I just don't know in what format.
I want it to do the following: When they click the import button, open multiple files (done) then save them as a settings. Then on form load, open those files so I do not have to re-import them!
I have tried this
CODE:
on form load and settings.txt included 2 file names and locations. It is only opening the 2nd file NOT the first. How can I make it open ALL files in that settings file? I also tied ReadLines
I know this is out there and probably illogical but I was wondering if it was possible to take multiple picture files and compact them into one file.... and then retrieve them from the program later? Way to combine any amount of image files into one file

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.
View 5 Repliesafter 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.
View 3 RepliesI 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

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'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?
View 4 RepliesOk, 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.
I'm trying to copy multiple excel source files into one excel file. My current code is working only for 3 source files..If more than 3 files are there, it doesn't copy the data but creates blank work sheet in the output excel file. Lets say I have a source folder with 5 excel files. Each workbook contains one worksheet with data. It copies upto 3 worksheets along with data into output excel file.
Lets say excel1 contains A as work sheet, excel2 contains B as work sheet ,excel3 contains C as work sheet ,excel4 contains D as work sheet ,excel5 contains E as work sheet .Now my output excel file should look like..OutputExcel with A, B, C, D, E along with respective data.But my current code is giving output as A,B,C worksheets along with respective data but its creating blank sheet1,sheet2 in place of D & E.

View 4 Replies[ 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 want to create my own extension without changing my registry file. I have a VB.NET project and I firstly want to create my own extension like ".abc" afterwards if there is any file like xxxxxx.abc when a person try to open this file I want windows to startup my project and open that file.
View 1 RepliesBasically, I'm trying to get a program to behave in the following way:First instance of the program opens up on PC1, opens a file for Read/Write access and then acts as the master program, doing a bunch of work on some other files I don't want a whole bunch of users accessing at once.Second instance of the program starts up, tries to open the file for Read/Write access, fails, enters Slave mode, opens the file for Read access, and periodically reads the status of the other files from this file.
That's the plan, anyway. If anyone can suggest a better way to handle the master/slave decision-making.Anyway, as a lead-up to implementation, I've got two instances of Visual Studio open. One is running a project called "GetFile", the other is running a project called "TryGetFile"."GetFile" has a Private myStream As IO.FileStream object and opens the test file using this line:
myStream = IO.File.Open("\[network path] est.txt", IO.FileMode.OpenOrCreate,
IO.FileAccess.ReadWrite, IO.FileShare.ReadWrite)
This works fine and, as far as I can tell, should leave this file accessible for further Read/Write access by any other process, which is fine for this stage of the testing."TryGetFile" also has a Private myStream As IO.FileStream object, but it attempts the following open code:
myStream = IO.File.Open("\[network path] est.txt", IO.FileMode.Open,
IO.FileAccess.Read, IO.FileShare.Read)
This doesn't work at all. I get an IOException, which reports that test.txt is opened by another process and I'm not allowed to play with it.Basically, I don't see what the problem is; I don't think "TryGetFile" is asking for any file access which "GetFile" forbids it from having. As far as I can see, "GetFile" shouldn't be forbidding any kind of access at all...

View 2 RepliesIs there a way to write a list of all paths and file names of currently open files. The best I can do is use the System.Diagnostics.Process class to grab the processes of the applications in which I am interested and then get the file name from the main window title for each process. There is no way to get the path for these files, however, with this approach.
