View 3 RepliesUse The Left() Function In VB 2010?
Oct 17, 2010I have a very small VS 2010 app that basically reads the records of a text file, adds some additional information to the end of the record read, and writes the new record to a new text file.The issue Im having is with the Left() function.I need to take all chars left of position 10 of a text box and add it to the end of the new record before I write it. When I use the Left() the "Error List shows an error related to this function.The error says:Public Property Left As Integer has no parameters and its return type cant be indexed.It gives two solutions: 1) Generate Method Stub Left in Project1.Form1 and 2) Generate Property Stub Left in Project1.Form1 When I select solution
1) that creates a warning indicating: Function Left conflicts with property Left in the base class Control and should be declared Shadows. When I select solution
2) that creates a warning indicating: Property Left shadows an overloadable member declared in the base class 'Control. If you want to overload the base method, this method must be declared 'Overloads.

View 4 RepliesString Class Does Not Have Left Function
Mar 15, 2010Since the string class does not have a Left method, how would you do this in VB.Net. I could use String.SubString(0, x), but the problem with this method is that it throws an exception if the String is not at least x characters long. Should I use the Microsoft.VisualBasic.Left function instead?

C# - .Net Equivalent Of The Old Vb Left(string, Length) Function?
May 9, 2009As a non .net programmer I'm looking for the .net equivalent of the old vb function left(string, length). It was lazy in that it worked for any length string. As expected, left("foobar", 3) = "foo" while, most helpfully, left("f", 3) = "f".
In .net string.Substring(index, length) throws exceptions for everything out of range. In Java I always had the Apache-Commons lang.StringUtils handy. In Google I don't get very far searching for string functions.
Edit:@Noldorin - My first encounter, although it took me several seconds to do the same in c#:
[Code]...
Note the static class and method as well as the this keyword. Yes, they are as simple to invoke as "foobar".Left(3). See also c# extensions on msdn.

Convert Callback Function From C++ To .Net?
Oct 20, 2010I'm trying to convert C++ API to VB.Net, but this function is too hard and i don't know how make it work.
Here is the API doc for this function:
void RemoteDllSetReceiver(void *inst, on_received_buffer_t received_buf_cb);
Sets a callback function to receive notifications from the DLL. The prototype of the callback is:
typedef bool (*on_received_buffer_t)(void* inst, const unsigned char *buffer, unsigned int size);
Where inst is the pointer originally passed to RemoteDllSetReceiver buffer & size contain the notification text as defined in the Remote Protocol. Note: notifications may arrive in different threads (e.g. network, timer, audio).
I can't imagine what i mus do with on_received_buffer_t, must it be a delegate? Like you can read, this functions returns notifications from the DLL like connection status, user id...

Convert Code C# To VB - Function References?
Mar 31, 2009I have some C# code I'm trying to convert to VB.NET. There are some external dependencies I'm referencing in each project. The C# line is
TWriteFileCommand writeFile = (TWriteFileCommand)CommunicationLink.CreateCommand(TOPKernel.TCommand.CommandType.WriteFile);
I don't really understand what the TWriteFileCommand in parathesis after the equal sign is for in that statement. When I try to do it in VB.NET, I keep getting errors because I can't get a reference to the CreateCommand function. The closest I've gotten is this:
Dim MyAppBase As OPSupport.App.AppBase
Dim writeFile As TWriteFileCommand
writeFile = MyAppBase.CommunicationLink.CreateCommand(TOPKernel.TCommand.CommandType.WriteFile)
However, I have a green underline after the equal sign @ MyAppBase that flags an error "Variable MyAppBase is used before it has been assigned a value. A null reference exception could result at runtime."What am I missing? Why in the C# code is the instance fine and what do I need to get the equivalent instance in VB.NET?
