I'm trying to make a launcher for a game I am making. The program works perfectly fine on my other computer. I recently transferred the source to my computer. I'm having issues though, I tried debugging the application and I got this error.
I figured out the issue. This code right here
.GetVersionInfo("C:\Users\eriger777\Desktop\test\bin\Launcher.exe")
Was trying to execute a file that wasn't there :3.
An error occurred creating the form.
Here's the code that's causing the error.
<Global.System.Diagnostics.DebuggerStepThroughAttribute()> _
Protected Overrides Sub OnCreateMainForm()
Me.MainForm = Global.Launcher.frmMain
End Sub

Let's start out by saying I'm not a terrifically experienced developer, so there is every possibility that I'm completely missing something here.
I'm implementing the Atlassian.NET SDK in a VB .Net solution. For the most part things work well, but I get the following error when I try to use the LINQ provider directly:
An unhandled exception of type 'System.InvalidCastException' occurred
in Atlassian.Jira.dll
Additional information: Unable to cast object of type
'System.Linq.Expressions.PropertyExpression' to type
'System.Linq.Expressions.ConstantExpression'.
The full exception:
System.InvalidCastException was unhandled HResult=-2147467262
Message=Unable to cast object of type

Dim myIssueQuery = From i In myJira.Issues
Where i.Project = "JiraProjectName"
Select i
Console.WriteLine( myIssueQuery.Count())
After doing some research I've become pretty convinced that this is an issue with how the LINQ provider is handling the query. This issue was reported to the developer a long while ago and marked as "Won't Fix" because the developer was not familiar with VB.
I'd really appreciate any assistance in either providing the developer relevant details to fix the issue on their side, or more realistically help pointing out what I'm doing wrong.
The Api for Jira can get a little complex and it is easy to end up using an older one that won't do what you want. I have had the best results using the nuget package "Atlassian.SDK".
With this it is relatively trivial to do what you want. this is C# code but I guess the vb.net can't be much different.
this.JiraConnection = Jira.CreateRestClient(jiraUrl, jiraUser, jiraPassword);
string jql = "project = TC";
IEnumerable<Issue> issues = this.JiraConnection.GetIssuesFromJql(jql, 100);
This allows you to use use the Jira Query Language to get the issues you want, which in my tests proved faster & more reliable than querying using Linq.

IT;S VB.NET not C# and i don't know how to exchange source from C# to VB.NET, THANKS
I want to get all paths from all running processes.
This is my source so far:
For Each p As Process In Process.GetProcesses
Try
ListBox1.Items.Add(p.MainModule.FileName.ToString)
Catch ex As Exception
RichTextBox1.Text = ex.Message
End Try
Next
But I can't get all path folders of the running processes.
If I examine the ex.Message, the response is like this
Unable to enumerate the process modules.
But if I not using ex.Message, the response is like this :
System.ComponentModel.Win32Exception was unhandled
ErrorCode=-2147467259
HResult=-2147467259
Message=A 32 bit processes cannot access modules of a 64 bit process.

Can anyone help me?
Take a look at the so-question How to get the full path of running process?
Instead of
ListBox1.Items.Add(p.MainModule.FileName.ToString)
try
ListBox1.Items.Add(p.Modules(0).FileName.ToString)
Edit:
Have you tried to evaluate the property of different processes directly? Maybe there is a certain process you cannot access, resulting in the error described.
You can try to iterate trough the processes one by one by creating the following loop:
For Each p As System.Diagnostics.Process In System.Diagnostics.Process.GetProcesses()
Try
Console.WriteLine(p.Modules(0).FileName)
Catch ex As Exception
Console.WriteLine(String.Format("{0}: Error - {1}", p.ProcessName, ex.Message))
End Try
Next
By doing so, you should be able to determine the processes you're not allowed to access and get a couple of processes you should be able to experiment with.
Mate the problem is obvious, you are targeting 32-bit but are testing your app on a computer that has 64-bit installed system, that's why you get the error.
Message=A 32 bit processes cannot access modules of a 64 bit process.
to fix this issue you should make the target 64-bit, there IS NO SOLUTION for this...
if you know the famous procexp (sysinternals) it has two separate application, when the system is 32-bit it lauches an instance of 32-bit, but when it is 64-bit it lauches another separate process for the system...
so if you want to deal with this issue, you have to make two instances for system compability,
Hope this is helpful
I am building a VB.NET desktop application in VS2013 that uses a .mdf file created in SQL Server 2012. I have the .mdf file imported in to the application. Along with the datagridviews I am using to view/modify the database tables I need to execute a SQL script when the user clicks on a button.
I have been trying several examples I've found, without any luck. I'm getting a FileLoadException error on the ExecuteNonQuery line:
An unhandled exception of type 'System.IO.FileLoadException' occurred
in mscorlib.dll
Additional information: Mixed mode assembly is built against version
'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime
without additional configuration information.
The "Troubleshooting tips" section has "Make sure that the file is a valid .NET Framework assembly". I clicked on that link, but the information there isn't very helpful to me, as I really am not understanding what it's saying.
I've tried these two examples so far:
Dim sqlScript As String = "C:\HL_Time_Entry_Reporting\SQL Scripts\stage_employee_hours_load.sql"
Dim connString As String = "Server=(LocalDB)\v11.0;Integrated Security=True;AttachDbFilename=C:\HL_Time_Entry_Reporting\Database\hours_analysis.mdf"
Dim connectionString As String = connString,
scriptText As String = sqlScript
Dim sqlConnection As New SqlConnection(connectionString)
Dim svrConnection As New ServerConnection(sqlConnection)
Dim server As New Server(svrConnection)
server.ConnectionContext.ExecuteNonQuery(scriptText)
from this site. And
Dim sqlConnectionString As String = "Server=(LocalDB)\v11.0;Integrated Security=True;AttachDbFilename=C:\HL_Time_Entry_Reporting\Database\hours_analysis.mdf"
Dim file As New FileInfo("C:\HL_Time_Entry_Reporting\SQL Scripts\stage_employee_hours_load.sql")
Dim script As String = file.OpenText().ReadToEnd()
Dim conn As New SqlConnection(sqlConnectionString)
Dim server As New Server(New ServerConnection(conn))
server.ConnectionContext.ExecuteNonQuery(script)
from this site.
One thing is, I'm not confident I have the correct connection string for this. That's the connection string I have for the datagridviews, which works fine, but is that also what I should use to connect for the sql script file as well?

It looks like you may be using an obsolete version of the SMO library, as explained here: https://stackoverflow.com/a/11286124/109122.
Update:
If the config setting recommended at the link does not work, try this simpler one instead:
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0"/>
</startup>
Unfortunately, it appears that the config file changes do not fix all cases.
I'm working on a directory Project where in when the program is not being use or idle for 3 minutes, a form that act as stand-by screen that plays a video will show (I use AxWindowsMediaPlayer). By clicking anywhere in the form, the stand-by screen will close and will be back to the main form.
The program works fine but SOMETIMES during the closing of stand-by screen form, the application crashes with the error:
AccessViolationException was unhandled. Attempted to read or write
protected memory. This is often an indication that other memory is
corrupt.
and this is the complete error detail:

This might be due to early binding of the standByScreen variable. Note that the error is caused due to the System.Windows.Forms class
Try:
Dim stndByScreen As Object
stndByScreen = standByScreen
stndByScreen.ShowDialog()
instead of directly using standByScreen

InnerException:
The entire application is extremely simple, it contained only code that initialize some of the supporting objects, however this particular Location type would initialize just fine but on first invocation of property getters/setters, it would throw the above exception.
I have been debugging this for a few days already and havn't found a way to instantiate and initialize the Location class properly.
Any clue? Some pointers on how to further investigate this?
