Verifying User By Type In Array
Mar 6, 2011
Okay, I will be using Username &'Type' through out my project to verify certain things. On workbook open, I grab the username. Now I want to put the username list and type into a public array. The username list has a range name of UID and the type has a range name of UIDType. The combined list has a range name UIDCo. Which will be more 'resource' friendly? To load UID into one array and UIDType in another or to load the UIDCo into one all encompassing array? I will very rarely use either list alone, it will almost always be a combination of UID and Type verification.
2nd question is, I've only really used 1 dimensional array's before, any help on where I can research more about multi-dimensional arrays. I can pretty much figure out the what it does and how to use them. I'd be more interested in the actual syntax or coding samples.

I am writing a scripting language which used .net for execution. Now I have written a function which accepts an object and return a set of numeric values. I wanted user to pass any numeric array (e.g. integer,single,double,long) and I could return values in that format. I mean user can retrieve value in any numeric array type rather than specifying an array type. E.g.

I have listBox control of user objects where each object has userName and Password.What I want to do is when a user enters userName and Password a method goes through the listBox checks for whether userName exists or not and if userName exists then matches the password.What I have in my mind is that to use for each loop but I think it would become complex so is there any better way?

I've see this application which can dig out our User Name from somewhere and asks our password. To be on the safe side, I typed my wrong password and it could cross-check that it was a wrong password and it asked me to type the right password. My question is:
How do you dig out logged in user's User Name?
How do you verify if a password given matches with the one really used to log into windows?
How do we auto-login by providing these verified details you say at a specific time by regularly checking the time using a timer?

Actually this is vb6 to .net converted code. I m getting compile error at following line
temp = Lset(DispElem(i)) bcz Lset is not supported in .Net Lset accept string data type for first parameter and interger for second.If you know any alternet solution or if you have any source code for Explicit convert UDT to string type and vice versa.

I need something tje user can type in data to such a parts QTY cost etc. There are no predefined parts list so the user can enter any part name/Number and there is no limit to amount of parts that can be entered.
Does anyone have any idea what might be useful. It was thinks of a listview bu i can't see that you can type into that. I cant use comboboxs because there are no predefined list and i know there is some way to generate text at runtime (i think) but i don't know how to do it and i would prefer a clearer approach.

I found C# code for it here. So I tried
Public Function checkProperty(ByVal objectt As Object, ByVal propertyy As String) As Boolean
Dim type As Type = objectt.GetType
Return type.GetMethod(propertyy)
End Function
But it throws an error at type.GetMethod(propertyy) saying "Value of type 'System.Reflection.MethodInfo' cannot be converted to 'Boolean'."
What to do?

I'm having to code hangman. So far I've done well, except for the part where I need to verify if the five character word contains a number. I also need to verify that the letter they are putting in does not contain a number. I have to use loop, so I'v considered using Do. Anyways, the loop needs to verify one character at a time that one of the character's is not a number. I know I can also use word like "[!a-zA-Z]" and that will verify the word does not have any numbers, correct? I have not assigned any value to letter yet, just word. Basically I've give the word length 5. I also know I need to use subString, but I'm not sure where in the loop.

I recently downloaded VB 2010 Express so i am quite new to the language, but i have worked with dark basic, which seems to b very similar.Anyway, my problem is that i cannot seem to correctly set out my array of a custom type/class. i am trying to create two arrays, one of available entities and another of selected entities of which the user selects the entities to be dealt with in irrelevant ways. i have creates a button (called test) which adds some entities to the available list and all the entities come back the same value but they shouldnt be as you'll c in the code. i have run the step into command a found that "available.item(#).Name = " will change all of the entity's names.As of current i am working with lists as the array kept asking for a 'new' statement but i couldnt figure out where to put it.[code]

I'm converting a user generated list box to an array and then generating a user defined number of random strings and placing it in a textbox.The code I have works fine as it will generate the number of random strings the user wants, except sometimes a line is blank at the top of the list but is counted as a string.

I am tasked with verifying an Enum contains a incrementing value. The code looks like this:

Each Enum value has a description (Custom) attribute also. The file and description attribute is used elsewhere... It looks like the programmers update the enums and use the custom attribute for help messages instead of resource files etc with a new integer value...

I'm trying to make my own control in for .NET using VB and I'm having problems achieving what I want to do. In fact, I'm making a control which inherit from the textbox class and the only modification I'm trying to bring to it is that if the control is visibly full, the user can't type anymore. So:
Scrollbars should never appear.The extended TextBox may be multiline or singleline.The extended TextBox may have different fonts and font sizes.Right now, the technique i'm using is graphics.measurestring to get a sizeF containing the width and the height of my string to compare it to the height and width of my textbox control. All this in the KeyDown event (I don't know of it's the best solution). I can get it to work fine for the width but I can't seem to ge the height right in a multiline textbox.

I have an application that downloads a .txt file via FTP, and then it calls some sql to insert the file data into my database. I want to check whether the file is in the correct format before trying to insert.
The file should consist of some number of rows, each with the following format:
(4 letter code) (tab) (3 or 4 letter code) (tab) (date as dd-MMM-yy) (tab) (variable length text description) (tab) (1 letter code)
Is there a good way to check whether every line in the file follows this pattern, and warn me if it doesn't?

I'm experiencing a problem while trying to verify an email signature that has sent from outlook 2007 and has been sign & encrypted. I receive this email on the other side (not outlook client) as a mime message (eml file). I have opened the eml file using ADODB stream into CDO.Message object. Now, i'm successfully managed to decrypt the message using CAPICOM object. but when i'm trying to verify the signature i get "incorrect hash" and the process fails.
I have to mention that i'm using as a base code the example from microsoft SDK for CAPICOM. I have discovered that if i sign & encrypt a message using that code example, i can (without any problem) decrypt and verify this email file. but when i'm trying to verify the signature of an email sent from outlook client there is a problem (like i mentioned in the beginning). I have also discovered that the content of the email is encode in UUEncode format. i have managed to decode the UUEncode format using BodyPart.GetDecodedContentStream but whats weird is that something goes wrong during that decode process i know that because on the code example we are trying to find:
BodyPart.GetFieldParameter("urn:schemas:mailheader:content-type", "boundary")
but i get an error message because this parameter cannot be found in the BodyPart. when i'm trying to read the text stream:
GetStream.ReadText
i seeing this weird thing... there are some binary characters that disturbing (apparently) to the function to find this parameter. here is the string:
Thread-Index: Acq1GI5RkfMs/4oXTO6yNp+vV7gabQ==
Content-Class: urn:content-classes:message
Importance: normal

When you inputted a username that already existing it will throw an exception, and when you change the username, it still throws the exception.

I am thinking of dialling the number and if it rang then it is existing but I am not sure how to implement such. I am on Vista and it looks like all comm ports are not available or that I don't know how to enable them. Upon googling I have found samples of TAPI but I am unable to make them work, the following code is supposed to call a phone no. but I am getting the exception "Value does not fall within the expected range." on the 2nd line and I am clueless as to how to fix it

I'd like to be able to do something like this:

I'm trying to figure the best way to verify the contents of a folder based on another count via a listbox. Here is my current code to count the number of PDFs in two different locations and total them together for a grand total.
'counts test1 pdfs
Dim f As String, c As Long
[code]....
I have another process before this that will create the PDF's based on the files listed in the listbox.What I am having trouble with is verifying that the PDFs that are created in the Test1 and Test2 folders equal the counts from the listboxes. This count needs to match before running the next process. I'm kind looking for wait or loop until both counts match, again before running the next process.
