Is it possible to open a file with the default program installed on Windows ? Lets say we have the exact location of the file on the hard disk and it is a *.pdf file , how can we give the order for that file to get opened by the default program ? In case it matters , I want to open *.pdf and *.doc files . It doesn't matter which program exactly will load the file , the default is fine by me .

I am deploying my application on a 64 bit windows 7 system (setting the platform property to x86) , after the installation process the app needs to set its connection string in the config file; and this is where I am having issues, the app is not able to write to the config file if/when its located under the program files directory (no admin privileges??), the app works fine when installed on a public folder.Please let me know how to give admin or write access to my app when its installed to the default program files directory

The biggest is obstacle is, how does my application know which file the user wants to open?
Just a quick qquestion. My application opens a web browser window with the click of a button. Today it looks like this: Process.Start("[URL])(It's not this website, but this is just an example.) This will open the requested website with a specified number at the end of the adress.

I have an application that works in both 32 and 64 bit, except that on the 64 bit system it can not open/ read/write any files.I know the 64bit file system is different, from what I heard. How can I make up for the changes? I have no access to a 64bit system, but I want to make my program able to find and open the files.

View 21 Repliesi was doing a fair amount of programming many years ago, like 10 it feels like, so I'm sorely not up to date on how my newly downloaded Visual Basic Express expects me to communicate with it.I am writing a program that pulls a cell from a database after the user has gone through several forms to determine which cells they want. When I write it like that, it doesn't sound very efficient, but I've designed it this way for usability.Here's where I have a problem: Should I store the path the user takes in a string, an array, what?
Here's an example:Someone wants baseball stats and trivia. They run my program, main form pops up, they select National League button, the NL Form pops up. Now the way my program is set up right now, is there are two ListBoxes on the form, one is populated, and as the user selects a Team from ListBox1, it jumps to ListBox2. Once they've selected all the teams they want info for, they click a button Next.
What I now need the program to do is show the next form "Team: name" once for each team, and insert the name of the team on the form in the appropriate label which I'll have blank. This form will also do the Listbox thing except the first listbox will populated with Topics like HR Stats, Pitching Stats, Coach History, etc.
I have recently published a simple text editor(just as an exercise). the editor has been published using Microsoft Visual Basic Express. Once the program is installed i wanted to make it a default opener for .txt files, so i clicked openwith ->Choose default program and then i was asked to show the location of the .exe. It seems like the .exe of my installed program doesn't exist. where the .exe is on a windows7 or tell me of another way of makeing that program the default opener.

View 5 RepliesI have a user of one of my programs reporting that they get an "access to the path...is denied" error during this section of [code]He's using Windows 7 x64 with UAC turned on. The location of "FilePath" is a subdirectory inside Program Files (x86) in this case.I tried to reproduce the error on my Windows 7 x64 system by enabling UAC (I usually have it off) but the program worked fine. However, in my case, "FilePath" is not in a protected system folder like Program Files (where write permissions are not given to normal users without admin elevation).So I tried to recreate this situation on one of my Vista x86 Virtual PCs where the "FilePath" would be inside Program Files. However, my program again worked fine. It had no problems writing to the Program Files folder with a normal user account, UAC turned on and no elevated permissions required.
Thus, I am confused. Why does it work for me and not for him? I want to try an x64 virtual machine but I can't with the software I have (Virtual PC doesn't support x64 guest OSs, VirtualBox won't run the software that my program interacts with). So maybe you guys can help me instead. Are the write permissions for the Program Files (x86) folder different between x86 and x64, or maybe even Vista and 7?
I normally install my application in a directory in the c: drive as the software is only used within the company.There is some simple security; the program writes a 'bat' file that gets the volume serial number this then this is used to generate a licence file. Both of these files are written in the application directory.I'm giving the program to an external client and am going to install the program in the program files directory - but I find I cannot write a file to the Windows 7 program files directory.

It says "do you want to open or save this file?. the file name is several random charactors with the tmp extension. do not suggest a virus. The tmp files in question are vs 2005 generated files. they contain html data indicating a problem on the form. If i close all the forms in the tabbed code area, and rebuild the project, then all is well. If i don't build the project, then when i open a form up onto the code area, i get a new download message. Anyone ever heard of this? I suspect IE8 but cannot recall if this all started when i installed IE8 or not.

I am trying to write a program that deletes temp files from my entire c drive. windows 7 will not allow any file manipulation. access denied . everything works fine in windows xp. what needs to be changed in my code to allow anyone to install this program on their computer and run it without errors like this. I need to change my code to correct this not windows 7, as other people will be installing this on their systems and they can't be setting their c drives. every answer i've found online is either to change c drive to have no security or set the code to demand uac to run as administrator(which doesn't work )

View 19 RepliesI have a program that needs to access the files that are open by another program on the computer.When my application comes up I can easily see if the other application is running with the .net Process.GetProcessesByName method
Dim MyProcesses() as Process = GetProcessesByName("AnApplication")
For Each Instance as Process in MyProcesses
If MsgBox("application is running - do you want to end it?", MsgBoxStyle.YesNo or MsgBoxStyle.Question, "Warning") = MsgBoxResult.Yes then
[code].....
The problem is that the Instance.Kill does not allow the application to end gracefully. In VB6 you could use the SendMessage API to send a close message to the application and it would end gracefully - i.e. give the user the normal closing prompt. This just slays the application - leaving any open files in their potentially incomplete state, etc.

View 1 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.
