My brother had his son make a simple maze program with Visual Basic. Now all exe files on his system open to the maze, even system restore opens the maze. They have windows xp and he usually can figure things out but this one has him stumped.

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 have a program that when you set it as the default program for opening rtf files, and open the file, not from the program, but from windows. It doesn't open it at all. It launches my program but, the file doesn't open in my richtext box.

I 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.

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.

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.

I have VB project and I tried to use PUBLISH feature.It seems to create nicely some kind of setup program, but the setup program does not ask where to copy files (it does not seem to copy filesto target machine "PROGRAM FILES".)Is this setup program somehow different from usual installers?
NOTE: I want that app files are installed to Hard disk( from USB stick source)Is the signing recommended or necessary? My App is pretty simple, its just using access DB + printer api, should I still sign?

I am trying to retrieve file details from files in the Program Files folder. I receive an error while trying to retrieve file details.
Dim sFileName As String = ("%ProgramFiles%Windows DefenderMSASCui.exe")
Dim Info As FileVersionInfo
Info = FileVersionInfo.GetVersionInfo(sFileName)
Msgbox(Info.ProductName.ToString())
I receive file not found error at 3rd line. But if I change the path from "%ProgramFiles%Windows DefenderMSASCui.exe" to "c:Program FilesWindows DefenderMSASCui.exe" it works fine.
What should I do if I want to retrieve file details from the path which includes a "%" character?

Having a slight permission problem with Win 7 I am guessing it will be the same on Vista but work fine on XP (yet to try)But my program is sitting in: C:Program FilesCompanyProgram And its trying to create new files alongside itself in the Program Files area but bombing out which I know is permissions. If I go there to create the file myself it comes up with a UAC prompt and when I hit allow it works fine but obv the program can't do that byiteslf so bombs out.Is there anyway I can over come that without the user having to grant admin rights to the program each time it starts or do I have to write data to another place?

I wrote a program to download and play AVI files the files are large in size and long time wise. I have the files playing as they are being downloaded but i can't see how long the file is or seek reliably. i was reading that the AVI headers are in the last 512kb of the AVI file *why would't they put it at the start* lol so my question is is there a way to download the last 512Kb of the file i'm downloading. i have the Bytes Read and Length of the file while its downlaoding i'm just not sure where to go from there, or how to do it atleast. If i had the length in time of the Avi file i could set the trackbar to be able to seek properly. or if someone has an idea how i could get the time of the video by using fps and some math i could prob do it that way too but idk how i would tell how i can find how many kb are in the fps i'm sure it changes so think that way is't going to be reliable. how to get the last 512kb would be the best option not sure if it can be done even.

I am currently working on a menu driven console program that so far has 4 menu options of checking internet connection, decrypting/encrypting a message, calculator, and a logout, and i am wondering about a few current things.
1. How do i make it to where, when a program starts for the first time, it asks for a user to enter in his data, like signing up for a site for the first time?
2. How do i make it to where the program will save the data entered, and does not delete when the user closed the program.
3. How can i make it to where when a user signs in, his/her data is read correctly? Like an array search for a multidimensional array.For my "New user" sign data i created a function...
Function createNewUser() As String()
Dim name As String
Dim userName As String[code]...

I have many container files on a hard drive, inside of them are many images. I have to get a particular image by using an ID to do this I have to go trough each of the container files and find the one which has the ID in it then I can retrieve the image.
I think I have 3 options:
load all the images at start up into memory, some images may or may not be used. as I need each image go through all the container files and open the image into memory. create a dictionary of IDs and what file they are in at start up and then get each image as I need it without have to go through all the container files.

In class i saved my program in with load of other test programs for the same assignment and got everything mixed up i finally figured out what was what and loaded the program in Visual Basic. Now my program doesn't recognize one of my forms when i try to access the design view of it. I hit run for the hell of it and the program runs with errors of course but the form1 "the missing one" shows up with all the buttons etc and i can use it.
Heres the link to the files. [URL]

I have a program where a lot of the required information for it is stored in text files. I simply read this information into large arrays. However, I don't think it's necessary to load all the information each time. Rather, it would be more efficient if I could simply search through a list of items to find the one I need and then use the data from it, or to find a similar name and use it elsewhere.
Would I be right in using a database? And is database programming done in SQL? I have a book on it telling me to use the SQL Server (IIRC), so I shouldn't be doing it in the VB.NET Express GUI?
Here's an example of what I would do:
Hex = 03 00 => dex number 003
Search in file Pokemon Dex Numbers
003 returns Bulbasaur
Check Bulbasaur base stats in the base stats file
etc
So basically I'm reusing a lot of information. I think a database would be best and it would all be internal right? I'm getting complaints about access denied to a text file (since it's stored in the program directory in the program files).
So to cap up the few questions I have:
-Databases are done in SQL and not inside the GUI?
-Databases would load internally?
-I could search a database without having to load it into like an array or something?

I am using Visual Studio 2008 Professional Edition, and I have a large windows forms project I have been working on. My computer froze up and I had to reboot. After reboot I opened my project, all the files loaded although I got a message telling me that the document load was skipped because of the way the project opened the last time. I am able to debug and run the program so the app is ok. but when I double click on a form to open it nothing happens. Even if i right click it and select "View Designer" or "View Code" nothing happens. No errors just nothing. I was able to open other projects with no problem but not this one, and this project is the only one that matters.

I have created a small application to open the Flash File from my VB.Net Windows Application. To open the Flash file - I have used the Shockwave Flash Object. When I run the application directly from the Solution, the flash files are opening perfectly. But, once I created the EXE and tried to open the same file, I could not. But I can still open other files such as XML, PDF, and Word file from the same directory.

In our application, when you go to "Menu > Help...", it opens our help files in Internet Explorer, which is the desirable effect. However, we have the shortcut key "F1" set to open the help files as well. It still opens the help in Internet Explorer... but it also opens them up at the same time in the user's default web browser![code]...
