Project Cannot Be Opened
Apr 1, 2012
I have a project the was written by someone else. I am very new to VB. I am trying to make changes the the project. When I first opened it it went through the conversion with no errors. The report has not errors however when I try to open the project I get the error "vbproj cannot be opened because this project type (.vbproj) is not supported by this version of the application". I am using VB2008 Express and have read all the other responses to the issue but Ijust do not know waht to do.

Okay, so I wrote a few custom ItemTemplates for VS2010 that implement IWizard in VB.NET (4.0). Straight forward enough. They work during my testing, but when someone else deploys and attempts to use any of them, Visual Studio throws an incredibly generic Exception has been thrown by a target of invocation error.
Stranger still, after they open up the project properties and try again... they work. Without changing anything. Anyone have any clue what is going on? Or perhaps even just a way of getting VS to give me a more specific error? I already tried devenv.exe /log but nothing out of the ordinary was there.

I made a Class Library project that contains the main classes that my Main Project needs because I don't want to main classes when I distribute my project. I've successfully called and used it in my Main Project. But when I started debugging and stepping through my code which involves calling and using the class I wrote in my Class Library, I noticed that the class' file in my Class Library opens up during debug mode.
how can I prevent the Class Library's files from being opened during my Main Project's debug mode?

When I open Microsoft Visual Basic 2010 Express, the following message comes up:
Quote: Microsoft Visual Basic 2010 Express. The automatically saved settings file 'visual studio 2010settingsvb expressCurrentSettings.vssettings' cannot be found. You can change this file on the 'Import and Export Settings' Tools Options page. The IDE will use your most recent settings for this session.
I click the 'OK' button, and the Start Page loads with the "Recent Projects" list on the left.
When I click on any of the projects to open them, another message comes up saying:
Quote: Microsoft Visual Basic 2010 Express. "Project Name" could not be opened. Do you want to remove the reference(s) to it from the Recent list(s)?
I read about a potential solution going to "%programfiles%Microsoft Visual Studio 10.0Common7IDE" but I'm not sure how to proceed. Does anyone know why this problem is occuring? Did I truly lose all my projects?

For reasons that are beyond my control, I have three Projects. Projects A and B reference project C. Project A references project B so that it can open a large form in project B. I now need to open that large form from project C, but VB won't allow me to add a reference from C to B because that would create a circular dependency. I found a way around it, though. I created a Timer in A, and when I opened C from A, I passed in that timer. When the user performs a certain action, I enable the Timer from A, and this causes C to open B for me.

I have a project that I have created, it something like a contact database.It is complete with its own sql server database, and controls and forms.I kinda of understand that I can include this project into another project.This is the tricky part,Can I include my contact project into another project and add more items to the database and forms in a new project?What I'm after is like using classes.My contact database would be like the base class, and the new project would be adding more features to that project.

If I need to run a sub from another form, I would normally do something like this:
DirectCast(Application.OpenForms("frmTest"), frmTest).PublicSub()
How would I run the sub if the user never opened the form? The form is an options form and it may not be opened by the user if they opt out of changing the default values. I don't want to change the location of the sub because the sub relies on a lot of info on that form.
I tried Google and playing around with intellisense, but I've come up with nothing so far.

I've got an application which I want to only have 1 open.How would I make it check if the application is already open and only open if it isn't? I've had the idea of using 2 forms, one of which is the proper application and the other which just checks if its running then opens the other form.I would imagine it would check if there's more than 1 of the process name running and if there is close all others?

I have a Visual Studio 2008-SQL Server 2005 app that will be throwing alot at it. It's my testbed learning app. I'm also a student of this craft(43 years young) like another poster posted on another thread. I come from a PICK/BASIC jBase background. Anyway as-is my app has a connection to the database that is opened on form load. I close the connection on form close. It's a one form app currently. Is this wrong? It seems that maybe I should not have a connection opened possibly all day. I'm looking into incorporating Datasets, dataAdapters into my next phase of evolution. I looked at the material and it's tough. For me anyway. But I will get into it. I will fetch the data into a dataset so that I can keep the connection open only for a little while. I was turned on to this "keep the connection just as long as you need it" idea from someth

I can't connect to my database now, although yesterday it was perfectly fine. An error message comes up saying "...A database with the same name exists, or specified file cannot be opened, or it is located on UNC share" this has never happened before. Why can't I access my database?

I'm trying to detect which contacts are currently opened, the only way I could come up with that was to actually get the items in the windows taskbar then compare the items to the contact list on Msn. This way when Bob@hotmail.com is currently opened my application can show a listbox of all the current opened Msn contacts. Is there an easier way to view the current open contacts with MessengerAPI

I have created a windows application which creates a database file and saves it to disk, it uses a custom file extension so that when the file is clicked it opens the application. In order for the application to use the data in the file it needs to rename the file so that it has a .mdb extension. My problem is that I cannot see how to get the name of the file which opens the application.

I'm exporting my Dataset to an excel file, and I want to make sure I keep any file errors under control. One in particular that I'm concerned about is accessing a file that's already open. A general IOException occurs that says:
"The process cannot access the file 'C:Reports eport300.csv' because it is being used by another process."
Here is the line in which the error will occur:
Dim output As New IO.StreamWriter(path, False, UnicodeEncoding.Default)
I guess I could just throw a try catch around it, but what if an IOException happens that isnt related to this particular incident? Is there a way I can check to see if the file is already open before allowing this code to run? Especially when I'm using excel.

I made a quick search program so when I browse for a text file, it adds that text file to a listbox1. And then when you search result will be placed in listbox2 Now I'm wondering how to force the program to automaticly load last opened text file on startup.I tried with this and then I stuck.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim reader As IO.StreamReader = _
New IO.StreamReader(winDir & "system.ini")

I've tried searching this forum for an answer to my problem with no luck. I've set my program to allow multiple instances of it to run. Is it possible for each instance of it to determine if it was the first, 2nd, 3rd, etc to be opened? It would be very useful if for example if the program has been opened a 2nd time I would like to be able to load a different set of parameters for certain things for the 2nd instance. The same with the 3rd instance.

I want my software to only opened twice. If they open it again, it will just put the current software in focus, instead of making a new instance. How can I do this?I also want to 'transfer' the launch parameter over to the other application that is already running.I'm terrible to explain my self, but if you got Steam, you can try it there and you will see what i mean.If you open "Steam.exe" from "C:\program files\steam\steam.exe", it will just open up steam window, with out starting a new process\instance of it.Example. If you already got steam running, and try to open this link: steam:install/70130, it will send that info to the current running process and start download the demo game.ing.

I have the code below:
Dim i As Integer
Dim objExcel As New Excel.Application
Dim objWorkbook As Excel.Workbook
objExcel.Workbooks.Add()
[code]....
At the end of this routine, eventhough the data was correctly saved to my Data.xlsx file, this routine also opened 15 EXCEL.EXE tasks in task manager.I thought that I had cleaned up before quitting. By the way, whether I write to 1 or 5 or 10 cells in Data.xlsx, 15 EXCEL.EXE tasks would be opened regardless.Is there a way to (easily and) completely close all EXCEL.EXE in task manager before leaving my application?

I'm launching an Access ADE, using Tony Toews auto FE program. The AutoFE programs will, if newer version available, copy the latest version of the ADE from the server, then launch it. My code looks like:
Dim stAutoFE As String = "V:Appsautofestartmdb.exe /cmd /inifile: " & """" & "V:AppsAutoFESSP.ini" & """"
Shell(stAutoFE, AppWinStyle.Hide, True)
System.Threading.Thread.Sleep(1000) ' Time delay
[code]....
I had to put the Sleep delay in, otherwise the GetObject would open the ADE a second time.But I don't know how long the copy from the server will take, so I need to remove that Sleep line and check that the ADE has opened.

I have a couple of files which I have to update periodically through a process written in VB.net . These files are on a server and part of a domain that many users can access. These files should never be written to as they are for reference only. I need to be able to overwrite some of them even if a user has them opened. Is it possible to do this? Presently the files permissions are not set as read-only but I can do this as long as the user under which the process runs will still have permission to overwrite them.
UPDATE: thx for your responses. The files are pdf and are opened by clicking on them from windows file explorer. This also happens when a user simply has the file selected in windows explorer.
