VS 2008 Using The CommandLine Arguments Properly To Open A File
May 5, 2009
I am trying to use the Command Line Arguments during the Form_Load event to load the file a user might have selected in windows explorer.
I have set some file associations during setup, so that any ".script" files will be associated with my application. However, my application can also open other (text based) files (it's a text editor), and I would like the user to be able to use "Open With..." and select my application to open the files in my application directly.
I have to use the Command line arguments for this, which will hold the filename(s) of the selected files, correct?
So I did this:
vb.net
For Each arg As String In Environment.GetCommandLineArgs()
If IO.File.Exists(arg) Then
OpenFile(arg)
End If
Next
Now, when I open a ".script" file, my application opens and the correct file is loaded. However, in addition, the EXE file is also loaded for some reason! It has opened two files, <Applicationname>.EXE and the file I wanted to open. Because the EXE file is obviously not just a text file, it just displays some random characters, but I don't want it to open that of course...
Also, if I run the application in the debugger (visual studio), it opens the <ApplicationName>.vshost.exe file... So I thought, I can check for the extension of the argument, and only open it if it is a ".script" file. BUT I don't want that! I also want the user to be able to select any file and choose Open With... and select my application. That won't work if I check for the file extension...

I have an application that has file extensions associated with it. The application has been deployed using ClickOnce. I have checked the associations table to confirm the entry is there and the association is to the 'ClickOnce Application Deployment Support Library'. When the application is triggered using a file with my extension, it does not pass the filename / directory in the CommandLine Arguments, instead you get the executable path of the application.
Which is under ..LocalSettingsApp"Random Strings"MyApp.exe
I have checked the Registry entry to confirm what the extension is set to open with and the application is dfshim.dll. Is there a way to overcome this, or is this just another limitation of ClickOnce deployment?

I have commandline strings that contains application paths and might contain arguments. Some examples:
1. "C:Program FilesMicrosoft Officewinword.exe" "C:some dirdocumentname.doc"2. "C:Program FilesSome Dirapp.exe" /dosomething3. C:Program FilesSome Dirsomefile.exe4. C:somedirsomefile.exe /whatever5. C:Windows
otepad.exe6. someapp.exe
I'm looking for a simple way to split the path to the application and the optional argument.Sometimes the string contains quotes around the path (1&2) and sometimes, even when the path contains spaces, the string does not contain quotes(3). And sometimes the string does not contain spaces in the path (4&5&6), but a space is used before the argument(4). And (6) is a executable without a path. I have to use the environmentvariables the find the fullpath of the executable. This string (6) can also have arguments.Is there a standard function available to do this split?
Note:I have a regex pattern to handle (1,2,4,5,6), but is doesn't work for (3), because of the spaces in the path."[ ]+(?=(?:[^""]*""[^""]*"")*(?![^""]*""))"I cannot control the strings. Some of them come from user input and some of them come from the registry.

I am working on a VB.net program that must get data from excel workbooks. I open the excel workbook, copy a chart image tp the clipboard, then copy the contents of the clipboard to a PictureBox.Image. The problem I am having is the files contain links to other workbooks so when I open them I get a message box asking if I want to update the links. Since this is ment to run automaticaly at certain times I will not be there to click on Yes or No.I also have a similar problem when I try to close the workbook. I get the messagebox for saving changes to the file.Here is the code I am using:
Dim objXLS As Object = CreateObject("Excel.Application")
Dim FileName, Sheet As String
Dim data As IDataObject
[code]....
objXLS.ActiveWorkbook.Close()'This is where I get the file save changes message boxI am using Visual Studio 2008 Pro and excel 2003My operating system is XP?

I am looking for a code snippet which opens a image, creates a clone of this bitmap in memory disposes this opened image so that all handles are closed.
Usually we can open a bitmap using this[code...]
the following code however keeps the Image File locked until the application is running, any suggestions how to dispose it properly. (So that no handle is left open )
Things i already tried: use dispose method of bitmap <= doesnt work (need to write implementation)
Using Block also doesnt work.

I have a form which won't open properly under certain circumstances if a particular Button is set to visible = false. Under the same circumstances if the Button is set to visiblbe = true the form does open properly or if the line of code at a certain place where it is set to either visible = true or visible = false is commented out or not there then the form opens properly. If any one of the 5 phases on my form are turned on then the problem doesn't ever occur but if none of the phases are on then the problem does occur. I just found a fix for the situation but I still am not clear about what exactly is going on.

This is my first time programming with visual basic, but the GUI I'm trying to create isn't complicated. So ,after looking at the tutorial for a bit, I got started.What I'm trying to do is run a c++ program which I created, but I'm making the GUI so that other people can use it easily.The c++ program needs arguments, so I have to text boxes on my GUI that will contain those arguments. One is a file path and another is an integer.I'm trying to run the .exe file for my c++ program with a shell script, but I can't get the syntax right.I don't want anything ecial I just want to run the program and pass it arguments. Here is what I have:I'm trying to use a shell command, as you can see.I can run the program from the visual studio 2008 command prompt by typing "cl DataRedux2.cpp" to compile and "DataRedux2.exe" to run.

I 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.

When running an executable file (written in FORTRAN) directly, there is no problem creating output text files. However, when launched from Visual Basic Express 2008, those reports are not generated. I also observe that the program launched from VB does not wait for a user prompt as it should. What am I missing?

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:
Public Class Program
Public Shared Sub Main()
Dim FurBase As New Core.clsDatabase

I have an application that I start from a sub main. Pass it some arguments and then open a form. Very similar to the log in form. Inside of this application I use 2 dll's. One I had written and another from a vendor. When I run my app from the IDE everything closes down ok. When I run my application from another application(similar to the command line start) the image of the log in box stays on the screen, until I move another window that does a screen redraw.
The process is stopped, by looking at the running process's on the computer. My next question, the dll that I wrote for it is a vb.net class(dll)... I do not have a destructor in it.. I just left the Protected Overrides Sub Finalize() alone which contains MyBase.Finalize() With my dll, could that be causing the window to keep itself drawn? Due to the two dll's connecting to device only within our network. Not sure if remote desktop or citrix causes a screen redraw.

I 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.

Basically my script doesn't properly close Word, and it still remains open. Then when I try to run the script again it says its Read-only as its opened..What I need it to do is - put the TextBox1 info onto the DOC - and print it. I don't want it to save, as it's a template. I've tried saving it somewhere else as a "temp" to get rid of this read only but it still doesn't work.Another issue also is that it's trying to close the document before the printing dialog disappears, so I've had to put a timer

When debugging my app it works fine i.e. It gets the two commandline args, through a loop, and execute as expected. However, once I publish it, the app only picks up the first argument, which is the .exe file string. Code below:

Dim args() As String = Environment.GetCommandLineArgs()
Dim n As integer = args.Length

This is the command line I want to use inside my VB.NET program. Look for the running process "mpc-hc.exe" and get the commandline of the running processwmic process where name='mpc-hc.exe' get CommandLineI want to retrieve the output from that command into a string. I know that it could be done natively in a VB.NET program and I have looked at how it was done. However, I cannot get the code to perform what it did in the commandline I have above.

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?

On 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?
