Overwriting Application Files While Running?
Jan 8, 2010
I currently have two applications. The main app and the updater app. When the main app checks his version with the webservice and it is out of date, it will download a zip archive and then start the updater. The updater will extract the zip archive overwriting the old files of the main app.
Is it possible to do this without the need of a 2nd app, in this case the updater? Can you like, store your application in the computers memory and overwrite the files?

I am having a problem where when I save some text to an XML file it overwrites originally what was in there, I want to be able to add to the file. The file looks like this:
<Incident>
<name></name>
<Department></Department>
<Incident></Incident>

I'm trying to edit an existing xls and just overwrite it without a prompt to overwrite. I thought it was something like Excel.DisplayAlerts = False but that's erroring with 'DisplayAlerts' is not a member of excel.
So this is my current closing code that doesn't work.
oBook.SaveAs(ExcelFilename)
Excel.DisplayAlerts = False
oBook.close()
oExcel.Quit()

But when same code i tried to run on Vista it gives the error. Error is as follows

Which is the best way to store application and user settings of an application running with multiple instances?My problem is that using the vb's "Application Settings" one instance would overwrite the other one.I want to identify each instance with a number passed via command line argument. I could use this number to identify the appropriate settings of the running instance, but I see in a local INI o XML file a better way to handle that.

Let's say 10 desktop shortcuts, all with different names/icons, point to and can start the same exe application from the same directory. Is there any means for the application to know the distinct name of the shortcut that was doubled_clicked. Also is there any means for a running application to know if it was started by command line, by a double_click on the exe, by a double_click on a shortcut that points to it, or by another process' call?

I want to run a jar file (like minecraft's jar) in my VB.NET application, to be specific: the jar should run in the Form. I already know that minecraft has a net.minecraft.launcherframe (is this right?) and that there is also an exe file for it.
I am trying to make a manager for minecraft that will allow the user to manage saves, textures, and (if i can access the internal files of the jar) maybe the skin. To make it really friendly, I am just trying to run minecraft in a form, just like the exe does.

I'm trying to run an EXE file using process.start.I've put in username, password and domain that it is accepting (it complains when I put the wrong password, and not when I put the right one, so it is checking etc), and that have local admin rights on the PC.However, when I try to run an EXE that's stored in Program Files, I cannot run it. It always says Access is Denied. When I copy that EXE to another folder, it runs perfectly![code]

The following code writes some data on an xml file. If I want to write on the same file twice the code overwrites the old data with new ones. How do I update the data instead of overwriting them? (i.e., write at the end of the xml file instead of overwriting the data)
Dim XMLobj As Xml.XmlTextWriter
Dim enc As New System.[Text].UnicodeEncoding()
XMLobj = New Xml.XmlTextWriter("C:" & current_scen & ".xml", enc)[code].....

i have made a program that takes info from your registry and uploads it so I can fix it and you can download the new version of a key that makes things work faster.... when someone uploads a file, it works good, and i can look at the ftp's text file and see it, but every time someone ELSE uploads something, it overwrites the previous text file and makes another one, which deletes the first one. i would like so that when another person uploads something, it will just be on the second line then third, so on so forth.
