Optional Method Parameter And String.Empty?

Apr 19, 2012

I have traditionally coded empty strings like this "", but for a couple of years now, I have been using String.Empty.I also normally never use optional parameters, but I'm refactoring a solution that's tied into my ERP, and I don't want to break anything. One of the changes was to add a parameter to proc, which pushes a new parameter into the method from which it is called. I coded it like this:

Optional BackReferenceID As String = String.Empty

But I got a syntax error "Constant expression is required." I guess String.Empty is non-deterministic??? Anyway, it seems like a bug. The workaround is of course to use double quotes.

VS 2008 : Use The DHCP API To Retrieve A Computer's MAC Address When Given The IP Address?

Nov 27, 2009

I'm trying to use the DHCP API (using the references on pinvoke.net) to retrieve a computer's MAC address when given the IP address but I can't get the code to work. I've run all the C# code on pinvoke.net through the C#-to-VB converter but I'm stuck now.

Here's what I have so far. The value of res is always 5 (should be 0). Thing is, I can't find any documentation on what the return codes mean

vb
Private Sub GetMACDim client As String = "1.1.1.1" Dim server As String = "0.0.0.0" Dim si As New NativeMethods.DHCP_SEARCH_INFO si.SearchType = NativeMethods.DHCP_SEARCH_INFO_TYPE.DhcpClientIpAddress si.ClientIpAddress = Convert.ToUInt32(StringIPAddressToUint32(client)) Dim res As UInteger Dim oInfo As IntPtr

A Procedure With A Single Parameter But The Input Values For That Parameter Are More Than One?

Oct 26, 2011

Is it possible to make a procedure have a single parameter but the values for that parameter are more than one? I have this procedure:

Public Sub autoComplete(ByVal cboCombo As ComboBox)
With cboCombo
.AutoCompleteMode = AutoCompleteMode.Append[code]....

Now I was wondering if there is a way to use it like this:

autoComplete(myCombobox1, myCombobox2, myCombobox3)

Or can I use a procedure like this with 'With...End With'?

ToolTips, Parameter Options, And Parameter Groups For New Code?

Dec 10, 2008

One of the things that I think is really cool about VB.NET is how built-in functions and subs have extra help text in their ToolTips like "Expression: String expression to search for replace string." as well as the usual "Replace(...parameters...) as string" text. So are the pop up boxes with things like "CompareMethod.Binary" or "CompareMethod.Text." And finally I like how some functions and subs have different sets of parameters for the same routine. For example, New FileStream() starts with either a path (string) parameter or handle parameter, but none of the 15 sets of parameters contain both path and handle parameters. Is there a way that I can set up the classes and functions I write to use these things or do they only work with built in classes and functions? If there is a way, what are the proper names for them so I can look them up in the VS/VB documentation? I would be happy enough if someone would give me an example of them, but it would be nicer if I could go through the documentation and find out if there are other cool things that are related or near by.

Making A Stored String Into A Web Address?

Dec 5, 2011

I'm attempting to use a product I've designed that stores 2 files on my web server space so I can access my stored data from anywhere. They are getting stored in the correct folder, but have several ___ (underscores) at the end of the file names.I'm sure it has to do with the way I bring back the stored string:My 2 variables are FILE1LOCATION (STRING) and FILE2LOCATION (STRING) They look just fine stored and recovered, but must not be.I recover them by the following code:

FileOpen(1, Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) & "myfoldermyprogmyinfo.dat", OpenMode.Binary)
FILE1LOCATION = " "
FileGet(1, FILELOCATION1_UPLOAD, 40)

Reading String From Process Address

Aug 20, 2010

This code should read the string "34,56,23,74,69" from a process's memory addresses (in this case notepad), right now it works but very slow and I think it even breaks somewhere. My problem is with the ReadProcessMemory function. I can't make it read an entire mbi.RegionSize into the buffer. I tried everything and now, it only reads 1 byte at a time until the mbi.RegionSize is finished then it checks if the text that was read contains the text I need to be found, then it goes to the next mbi.RegionSize. Now, even with notepad which is very small it still takes 10 seconds to find something and I intend to use it with a much bigger program, so it will take like forever. Another problem is that it only finds the string "34". If I put "34,5" it won't work.
