Boolean Function To Return Whether PC Is Connected To Internet?

Jun 6, 2013

I want a boolean function to return whether the PC is connected to the Internet. How to start creating this.

Reason:

I have code that checks an online database and downloads data after the user presses a button.If the host computer is not currently connected to the net, I would like to display a message of my choice instead of trying to run the code.To determine whether to run my message or not, I need a function that will return TRUE/FALSE if the host PC is net connected or not.

Check If Connected To Network

Jan 11, 2008

I have created an application for users that requires the user be connected to the network. I wanted to do a check to see if they are connected, and if the user is not connected they would get a message box telling them that they need to be connected to the network, then the workbook would close. Below is the code I have, but when a user is not connected they do not get my messagebox, instead they get the excel error message "excel run-time error '52': bad file name or number", and the debugger line that gets highlighted is in the function DirExists that checks the length of the directory of the file path: Len(Dir(strpath))

Option Explicit
Function DirExists(strpath As String) As Boolean
If Len(Dir(strpath)) = 0 Then 'this is where the debugger highlights
DirExists = False
Else
DirExists = True
End If
End Function

Private Sub Workbook_Open()
Dim strpath As String
Dim strfile, strfile2 As String
strpath = "\n530fs1PCLFileSharespcl_repositPricing_ToolsPAT"

Selective Columns In Connected Workbooks

Mar 20, 2014

I have a workbook with several columns, some of which are for internal company use only.

Sometimes we need to send an updated list to business partners, but they don't need all columns.

Is it possible to make another workbook which takes only specific columns, and excludes the stray info at the bottom of the original workbook? See examples.

Alternatively: Would it be simpler to make an extra sheet in the original workbook, and somehow choose "Safe only this sheet to a new document" whenever someone requests the list?

Is it a solution around this 'problem' or does sheet-1 always has to be visible ?

Calculate A Lot Of Averages Of Non-connected Values

Feb 20, 2008

Situation: I need to calculate a lot of averages of non-connected values. That is, they are separated by several rows (which also contain values). So far, I use the code-sample below (just to illustrate), which is not really elegant. Unfortunately, it seems that this technique comes to its limits when a high number of different non-connected values are combined into one string and get assigned to a formula- range (last line of code), which is where the program stops.

My question is: Is there a nice way to solve this? A way, which is not limited by the amount of data processed? The only way I could think of, would include a UDF, where a sum, sums all values up and then devides by the number of added sums ... but this would be relatively slow, and I have an awful lot of values to be averaged (100 sets * 6 rows * 200 values = 120.000 calculation- steps), as well as STDEV and a Standard Error of Mean (SEM) to calculate. Is there a better alternative?

Const intCells=9 'actually, this is no constant but a variable
Const i=4 'actually, this is no constant, but a nested for- loop-value
Const intLinesInBetween = 12 ' amount of lines, which separate my values
Dim j As Integer 'simple counter, runs through all cells
Dim rngUpperRow As Range 'Range of the upper row = normalized time vector
Dim rngCurrentRowAvg As Range 'current row into which avg formulas are inserted
Dim intCells As Integer ' amount of experiments in range............

Boolean Value For Each Worksheet

Jun 15, 2008

I have a timecard spreadsheet which im working on, each employee is represented by a single worksheet in the workbook, and the worksheet is named after the employees name. New employees are added by filling in a form which dynamically creates the timecard based on a template. Im trying to impliment a 'Fire Employee' button which sits on each employees sheet and can be clicked to set an employees working status to false by changing a boolean variable called 'fired' to true.

Ive been looking around the forum but I cant figure out if i should be using public variables or where exactly i should be placing them, so that each employees 'fired' status is set to false when the worksheet is first created, but can be set to true when the 'Fire Employee' button is clicked, this must only set true for that specific employee, and not all employees. If your wondering why i need this, the employees work status will be used on other forms to toggle views etc so thats why a boolean approach is best (at least i think it is if its not to difficult to do)

Using Boolean To Compile Knowledge...

May 29, 2009

I have minimal excel knowledge, but enough to get by. I have 2 years in C++ programming.

Here's what I'm trying to do:

I'm trying to create a workbook to keep track of flags we send out, and receive back. We have a lot going and coming, so I figured the best way to do this would be to break down each region on different sheets. But I need to create a check box that says something like, "Yes/No" or "Here/Gone" or something like that. THEN, I need to take that information, and put it on the front sheet of the workbook so I know how many we have in/out total. Does this make sense? I know how I would program this in C++, but excel is a bit different.

Defining A Boolean Without It Having An Actual Value

once bTest is declared as a Boolean, it becomes equal to FALSE (I checked this after much head scratching). How does one assign a value to a boolean variable only after you make your test.

Boolean Based On Cell Value

Jan 22, 2010

I need help creating a code that does the following:

I want a Boolean variable (TheTD) to be True when and only when the value in cell A1 is "TwoOnly". Once it isn't then I want the Boolean to be immediately False. Once cell A1 is "TwoOnly" I want TheTD to be true immediately as well.

I am using a userform and the textbox1_Change macro can change the value of cell A1 while typing. So in other words The Boolean can be changed from True to False multiple times depending on what I type in textbox1.

VBA Combinatorial Boolean Arrays

Jan 28, 2010

I would like to construct in VBA "n choose r" Boolean arrays of length n which will give all possible combinations of these variables as you scroll through the arrays.

Typical values of n and r would be 40 and 5 respectively and I'm looking to get the fastest possible output on these 660,000 or so arrays.

I have been playing around with various "for, to" statements but haven't managed to turn out anything meaningful thus far.

Boolean Logically: Post Data On The Right Pages

Nov 11, 2008

i need someone that can think through this boolean logically. its been a long day at work and now I'm trying to walk through this boolean thing to make sure my data will post on the right pages.

I have an Excel Macro that will capture inputted customer/vehicle data from an input screen, at the end, based on questions answered, i need to place that data on 1 of 4 sheets in my excel document.

The questions are:
Is this a Nationwide claim? (Y.N) (boolean = nw)
Is the vehicle here? (Y/N) (boolean = vh)

So here's what i got
if NW = true and VH = True then place data on "sheet1"
if NW = true and VH = False then place data on "Sheet2"
if NW = False and VH = true then place data on "sheet 3"
if NW = false and VH = False then place data on "sheet4"

I can't think of how to write this IF statement for this to happen. can't get the logic going.

OR IS THERE A BETTER WAY?? i'm sure there is.

Move Data Based On Boolean Operators

Mar 26, 2008

I'm trying to figure out how to reorganize data based on boolean values in two different columns. My goal is to write something in VBA that will look to see if the boolean in the first cloumn is true then procede to check if the boolean in the next column, same row is true. If that is the case, it will take several values from the row and move them to another worksheet. If the boolean in the first column is true, but the second column is not, it will look down the rows of the second column until it finds true then move several values from rows it has passed through. Here is an example of the sample data I will be dealing with.

Date Time Duration Boolean1 Boolean2
6/22/200715:0032TRUETRUE
6/22/200718:0058TRUEFALSE
6/22/200719:0060FALSEFALSE
6/22/200720:0060FALSEFALSE
6/22/200721:0060FALSEFALSE
6/22/200722:0060FALSEFALSE
6/22/200723:001 FALSETRUE

Based on the example data my goal is to move the data in a new worksheet that would look something like this

Date Start End Duration
6/22/2007 15:28 16:00 32
6/22/2007 18:02 23:01 299

DATE Function & IF Function (return A TRUE Or FALSE Based On A Date In A Cell)

Dec 8, 2009

I am trying to return a TRUE or FALSE based on a date in a cell.

for example:

if cell A1 = 07/11/2009

I want A2 to show TRUE or FALSE if A1 is 14 days or more behind todays date.

I have tried stuff like:

=IF(A1=TODAY()-14,"True","False")

but it just always says false. EDIT: I have just noticed that if I change the date in A1 to exactly 14 days behind todays, it returns TRUE. So, it does work. Do I need to add a GREATER THAN in there?

Capture The Cancel Property (Boolean, True Or False?)

Oct 8, 2009

This macro adds a comment to a cell and some text from an input box. I store the last value entered in the input box via the registry, it is recalled as the default input box value. How do I capture the cancel property (Boolean, true or false?) so the ActiveCell.Value remains and comment is not added? When a user selects Cancel/X the macro deletes the value in the cell and add's a comment. This overwrites existing data with "" (nothing).

Excel 2007 :: How To Pass Boolean Variable Between Two Macros
