i have an array of 30 strings , the names of the commands send to the serial port, the serial port adresses 16 devices. each device has its own set of commands.
of course i could make subarrays for each device, but for the saving of memory it would be better to use a integer index to name the commands, so like command 0 to 30.
dim command(29) as array of strings.
dim device(7) as array of devices.
I have an address in the type 'array of bytes' (example):
81 ?? ?? 02 53 02 d0 27
To mess with it in visual basic, I use the format in Hex:
&H81 &H02 &H53 .....
I do not know what 'put' in relation to the 'question marks' I've tried:
&H??
&H_
&H00
And even leave it blank.
where i put the *'s i get the error "The parameter 'address' cannot be an empty string. Parameter name: address".

I have been assigned to create a simple address book in VB 2005 and have got as far as I can with it. Contact entries are to be stored as an array of objects rather than to .txt file or access database (I know they will all be lost when shut down). I suspect this is probably pretty straightforward if you know anything about VB - unlike myself obviously.

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)

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.

How can I extract the IP address? 173.234.120.242
I am experimenting with more effective ways to generate forms. My experiments goes into the possibility to link strings, and other types, directly by their class reference and use it to update the original values without any strongly typed code.
I have been using GCHandle.AddrOfPinnedObject to get the memory address of the string, but it gives the the memory address of the string data, not the string class/reference that i need to change to allow me to use this approach.I am aware that strings are immutable and can not be changed (Actualy, you can, but its not recomended), but I do not want to change the actual strings, but change the reference to it (the string object).Is there some other way to get the address of a string object reference?

I have a DGV and a button to open a browser window to an ip address and also a button to open the ip address gateway. I can open the ip address that is displayed in the DGV no problem. What I am stuck on is opening the gateway address. So for example I click a record in DGV then the button and my browser opens to 10.15.2.248 What I need to do is replace 248 with 1 The ips will all end differently though for example 10.20.2.34 , 10.256.34.4 and so on. So as far as I know I will have to trim to the last period and add a 1 How can I do this?

But the email address is in a perfectly legitimate format (I changed the email so I don't get killed with web-crawlers pulling addresses, but it is the exact same format). Hope someone can see what I am obviously missing.

I am using this regex string in one of my programs to validate email adresses: "^[a-z0-9._%+-]+@[a-z0-9.-]+.[a-z]{2,4}$". This works well for the most part, but I just found out that it doesn't catch an address like this ... "john.doe.@yahoo.com" ... where there's a "." right before the "@", which is invalid, so my program tries to send it & throws an exception. How to modify my regex string to catch this situation?

i have tried various ways to accomplish this, but to no avail. I don't know how to generate the replacement text (mailto link) so I just used a bunch of x's until I can figure it out. Here is what I have (which currently not replacing emails in string): Here is my Code behind:

searching through memory at a given address range, and match a string of bytes specified i.e.

The function should return the address start of where the array of bytes was found.
I work for a printshop that screenprints customized hats ,tees and a host of other stuff for a variety of small businesses. Being that we are a small business as well, we can't afford to mass ship catalogs to our clients, so I decided to build a catalog application/business card that can be emailed to them. The app is rep. specific, and after choosing which options suit them best using text fields and combo boxes, upon clicking submit, the customers' info is emailed to the rep.
To do this, I am trying to get a popup window that displays an email form with the 'mailto' address previously set, so it can't be altered and the info from the previous screen to be pasted in the body of the email. Upon clicking the confirm button, the mail is sent and the window is closed. I already have the code to copy the info from the textbox and combobox entries and paste it into the textbox in the next form, but getting the email form to be functional is appearing to be quite a feet.
I am trying to create a new MailAddress, the email is coming from Request Parameters, that is: Request.Params("fromEmail"). It is actually being sent from an android device through an http request.When I try to create a new MailAddress from this email, I get the error "The specified string is not in the form required for an e-mail address". When trying to create it directly, that it ma=new MailAddress("a@b.com") using the same coming string, it works, but creating it using ma=new MailAddress(Convert.ToString(Request.Params("fromEmail")) produces the error.
