How would I be ables to copy the content of a directory to multiple target simultaneously, like writing on 4 usb keys at the same time. Is that even possible?
I tried divide the task with threads. I tried to create a thread with:
dim t as thread
t = My.Computer.FileSystem.Copydirectory(source, destination)
t.start()
but the code doesn't work, "my.computer.filesystem...." won't work.
I need to be able to set the "overwrite" parameter to True AND pass a value to the "showUI" parameter. I found on msdn these are the uses but unfortunately it doesn't seem to allow both those parameters to be declared at the same time.[code]

View 1 RepliesI'm using the x86 target CPU setting (and .NET 2.0 as target framework if that's important) for all of my projects and components. This worked without any problems with Visual Studio 2008. My developer PC uses a x64 version of Windows 7.But now I have a new project in Visual Studio 2010 where both, the main project as well as the user control component is set to x86 target CPU, but I still get following error when I try to run my main project with the user control placed on the form:
"Could not load file or assembly 'XXX' or one of its dependencies. An attempt was made to load a program with an incorrect format."
This is the normal message e. g. if the main project has a target CPU of "Any CPU" and the component only "x86", but in Visual Studio 2008 it worked fine if I set both to "x86". Why this is not working in Visual Studio 2010 anymore or what I need to change that it works again?
I just installed Visual Basic Express 2010. I am doing a project at the moment for college. The project is running fine on the computers at college. But when I try to run it on my home PC I get this error message.QuoteWarning1: Possible problem detected while building assembly 'StockSYS': Referenced assembly 'Oracle.DataAccess.dll' targets a different processor..I have Googled it but when I go to the advanced compiler settings, there is no option to change the target CPU, just an option to change the target framework. I know that this has something to do with trying to run it on a 64-Bit OS. I just don't know how to change the target CPU.
View 9 RepliesI need a function which can determine the target website of a *.url file.
Currently I develop a web browser. When you drag a file onto the exe in Windows 7 or pass a URL as a parameter to it, it will open that file/website (at least attempt to). I will fix this code and make it only open files that has HTM, HTML, LNK or URL file types, maybe also some picture files and similar as well. Here is the code I currently use to detect the command line parameter:

My VB.NET 2010 app currently targets .NET 3. I have to update it to target .NET 4 to get around some Locale / CultureInfo issues. What's the difference between .NET 4 Client Profile and the other .NET 4s I have on my machine: Extended and Multi-Targeting Pack? Which flavour of .NET 4 should I target? I want to target the flavour that the average user running Microsoft Office (Excel/Word/Outlook) out in the wild is most likely to already have. Why (on my machine) is there only a regasm.exe for v2.0.50727 and v4.0.30319? Why not a separate version for the other versions installed on my machine? (3, 3.5)
View 2 RepliesI am currently trying to read the target line of a shortcut file, if you were to right click and view properties of a shortcut, you can see the target line which holds the path of the file for execution. I problem is the target lines have attributes/properties at the end of the target line. The code i have atm reads everything except the most crucial part, the data after the .exe.. For example
Say i have a shortcut file whose target line(if you view properties of the file) is as such:
\adminappsVbNetSQLScriptRunner.exe AccountNumberUsage
My current program reads in this part of the target line..
\adminappsVbNetSQLScriptRunner.exe
But i need the last part, its the whole point of the program...why it stops reading when it hits the .exe or how to make it continue till end of the target line. I eventually store each target line returned into an array which ill export to excel later on.The code used to retrieve the target line is below.
Public Function GetTarget(ByVal dt As System.Data.DataTable)
Dim path(dt.Rows.Count - 1)
Dim wshLink, strPath, wshShell
Dim rc As Integer = 0

I recently wrote a quick VB.NET app that injects a DLL into a running process. To test it I was creating my own vb.net Class Library project which simply spawns a "Hello World" message box in hopes of it showing up in the target process once I injected my HelloWorld.DLL.My problem is that the message box never shows up after I inject the HelloWorld.DLL. I'm pretty sure the reason for this is because once my HelloWorld.DLL is injected (since it's a VB.NET DLL) it does not have a DllMain and hence has no idea what to execute and nothing happens.

View 1 RepliesI have a ListView called "orderReceiptTable" which I am able to properly access from the Code Behind. Within it is a literal called "orgName" which I obviously would like to populate with an organization's name. After much searching it was determined that FindControl was the right course of action. Perhaps I am using FindControl improperly but I am unable to actually have it "find" my Literal control. The code block is being called in the Page Load.
My code looks as such:

Dim myOrgName As Literal = FindControl("orgName")
myOrgName = CType(orderReceiptTable.FindControl("orgName"), Literal)

View 3 RepliesI am using VB.Net 2008 Express.I am trying to move a button on a form, the button status is unlocked. The code that I want to use is:
Me.btnEnter.Location.Y = 474
However, I get the error message, "Expression is a value and therefore cannot be the target of an assignment" If I now code as follows, I get the error message, "Property access must assign to the property or use its value"
Me.btnEnter.Location.Y
The errors appear contradictory. Just to check, I wrote the following
X = Me.btnEnter.Location.Y

I'm working on an application that contains a "BackgroundWorker", the "BackgroundWorker" worked fine but after I started to change some stuff it gives me an error ("Exception has been thrown by the target of an invocation.")... I used a breakpoint to see where it happens, the exception gets thrown at the "End Sub" line of the BackgroundWorker.I then deleted all the code inside of it and ran it again.I still get the error.
View 12 RepliesWhat is the meaning of this error message?
"Exception has been thrown by the target of an invocation"
Instead of words, here is my code's logic :
while loop
run BGworker01
run BGworker02
...
run BGworker09
application.doEvents
thread.sleep(10)
end while
All the bgWorkers do the same thing (sending some data, only to different locations). When I run this loop with only 1 Background-Worker, it's all fine, but when I add the other bgWorkers i get the mentioned error at the "application.doEvents" part of the loop. I think it also points to another place (highlighted in green) inside one of the bgworker's code :
Dim FileStreamToSend As FileStream = New FileStream(fileToSend, FileMode.Open)
I thought it might be a problem that all bgWorkers are trying to read from the same file together, but when I tried using different file for each bgWorker, the problem persisted.

I know this is a relatively common error but I am working in an application that allows custom reports to be written using vb.net or C# for scripting. Error handling is very poor and I am not knowledgable enough to add my own (if it is even possible).
My code simply retrieves a value that is stored in a textbox on the report formatted as LastName, FirstName and truncates all characters after the comma. This value LastName is placed in a new textbox on the report. Here is my code:
Sub Detail1_Format
Dim lastNameFirstName As String = ""
Dim lastName As String = ""
[Code]....
The error happens when I use lastNameCommaIndex to set the number of characters in my substring. If I replace it with a number the report is published properly.

In Visual Studio i can select the target .net framework version, which for example defaults to 3.5. Now when i build my application with this setting, i guess it wont work on computers with .net framework 3.5 not installed, right?But lets say i choose .net framework 2.0 as target .net framework. Will my application work on computers that have .net 3.0 or .net 3.5 framework installed, but not 2.0?In other words: Is the .net framwork always backward-compatible?
