Using User-defined Function In Sql

So I've got some data, which has the approximate form of a sine function. I want to find all the x-axis intercepts. I tried using the intercept function and swapping around the y values for the x values, but it only returns 1 value (so I'd guess it uses a linear regression to estimate a single line through the axis).

I was thinking of trying a nested if/and statement but I haven't quite figured out how to do it. Basically I want to identify the two values where it switches from positive to negative and also indentify the values where it goes negative to positive, I can then fit a straight line between them to find a better approximation of the intercept (though it might not be necessary). Preferably I'd like it all one function as I'm not doing it in VBA (I might do later though, we'll see).

Can anyone suggest how I'd find these value or the x-intercept. Any help would be greatly appreciated.

Since there isn't a ISDATE function in excel.

The following can be used to simulate the same, and avoid having to achieve the same with VBA's IsDate function:

STEPS:
1- Format the column (ex A) as text

2- Formula to check for valid dates:
=ISERROR(DATEVALUE(A1))

I have a excel spreedsheet that contain external data. I would like to put a
button in the excel sheet to update the sheet without doing right click and
refresh.
My user here are very dummies.

I have a sheet with a list of names on and I've noticed that when I use ctrl+F to use the find function, even when I know i have entered the correct name it still will not work. I have identifed times when I know the name is there on the sheet, but the find function says "Excel cannot find the data you are searching for"

Im unable to put any pics up as my work pc has java disable so photobucket ect won't work but has anyone else come across this problem and how did you rectify it? A search macro perhaps?

Hi all, the title pretty much says it all, I have a form where I am trying to create a button that will pop up a window where the user will browse to the desired folder and once that folder is selected, the path will be copied as a text string into the cell adjacent. My command Button cell is in B3 and the path should be shown in C3.

Can anyone help?

Thanks

Hi there,

I have a piece of code called ConvertDates that formats data contained on 6 worksheets. The 6 data sheets all contain a data connection to a website of foreign exchange tables.

What I want is for my code to execute as soon as the data connection refresh has finished.

When I use the statement

Code:

ActiveWorkbook.RefreshAll
Application.Run "Project1.xlsm!ConvertDates"

The code executes the macro whilst the refresh is still happening, thereby screwing up my results. I don't really want to use a timed wait, because the refresh speed is going to vary from user to user.

Is there some way I can tell excel to wait till the refresh has finished and then execute the code?

Any help would be hugely appreciated.

I have a UserForm with several fields on it: 5 are 'required' and the other 6 are 'optional'. If a user doesn't enter a value for ALL of the 5 'required' fields, how do I get the code to return the user to the UserForm (with, I assume, the values they already entered, still showing)?

I have the AutoOpen code that starts things off, and then, in turn, loads the UserForm with the fields that need to be populated.

I can't figure out how to route the user back to the UserForm, to enter the 'missed' data.

I'm trying to use VBA to go to a website that requires a User Name, Password, and a Submit Button.

So far I can get everything to work besides the Submit part. The code runs without errors, but doesn't actually "hit" the submit button on the webpage.

For posting, I removed my actual user name and password and and used the generic " User Name " and " Password " highlighted in blue.

I highlighted another section in green that I took from a previous post hoping it would solve my problem. The link is: http://www.mrexcel.com/forum/showthr...xplorer+submit


Here is the code I am using:

Sub GoToWebSiteAndPlayAroundNew()

Dim appIE As Object ' InternetExplorer.Application
Dim URL As String


Set appIE = CreateObject("InternetExplorer.Application")
URL = " https://efolio.morgankeegan.com/escripts/defaultLogon.asp?errCode=2 "


With appIE
.navigate URL
.Visible = True

Do While .busy: DoEvents: Loop
Do While .ReadyState 4: DoEvents: Loop

.document.getelementbyid("fUserName").Value = " UserName "
.document.getelementbyid("fPassword").Value = " Password "

End With


On Error Resume Next
x = 0
For Each mitem In IE.document.all
mitem.Value = "x"
x = x + 1
Next

x = 0
For Each mitem In IE.document.all
If x = "Submit" Then
mitem.Click
Exit For
End If

Next

End Sub

Is there an Excel guru that can help with this - its related to "drop down menus"


I have 2 colombs of data.

AT the bottom of the first, I have created a drop down menu using the "data validation" feature in excel.

At the bottom of the second colomb, I have used an "IF" function that returns a result, which depends on what value is chosen from the drop down menu in colomb 1

The problem I have is that I want the TRUE result from the IF function to be another drop down menu, being the data in colomb 2.


How do you write an IF function where the TRUE result is a drop down menu??
I tried to create a drop down menu of colomb2 elsewhere in the spread sheet, and used that cells location as the TRUE value, but this didn't work either...

ANy suggestions??

In Excel there is a difference between cells that are blank (= "") and that are empty. You can make blank cells empty by selecting them and pressing the delete key, but I need a fast way to do this on all blank cells in a large worksheet. The only way I have found is with a VBA macro that loops through every cell, tests for '.Value = "" ' and then uses the '.Clear()' function, but doing this on 30 columns x 10000 rows is far too slow. Any solutions?

(The reason I need to do this is for importing into Access, the database treats empty cells as NULL which is what I want. Blank (but not empty) cells screw the import process up.)

Hi
I am a new user and trying to setup a database in excel. I can select all addresses and copy but when trying to paste into excel it does so in 1 cell.

Is there a way I can paste the separate email id's into individual cells so I don't have to do it individually?

Many thanks
Patrick

Hello,

I'd like to be able to copy data from a list of websites into Excel. It would take too long to navigate to do an Excel web query for each site, so is it possible to write a macro that could do that?

Thank you!

Hi All,

I am trying to make excel automatically add a leading zero to values which are 5 digits long;

i.e. number input is 15185, then excel automatically changes it to 015185.

If I put a Customer Number Format of 0##### it works, however, a user could put any length of number into these cells, and if the number is less than 5 digits I don't want a leading zero.

Is there any way of writing a small macro to sort this out.

The numbers would be input into range B16:223.

Many thanks,


Andy

file locked for editing , can I kick the other user out if its my file?

I have made an excel file where other people have to go in and update it. This process takes 2 secs but some people forget and stay in it over lunch etc causing a great annoyance.
Is there anyway I can "kick" them out my file? Im not concerned if they lose any data they've entered as I'm sure this will help them get the message to get out the file quicker..
Its really doing my head in... pls help

This is probably an easy question for most of you, but it's killing me. I tried searching before I posted this, but the suggestions given didn't seem to work for me.

I need to look up data from a cell on one Excel sheet, compare it to a list on a 2nd sheet and when they equal, take a value from a different column on the 2nd sheet and drop it back on the 1st sheet. Since that's a horrible explanation, let me try explaining it this way:

Sheet 1
Column A has a long list of code type 1s
Column E has a long list of code type 2s

Sheet 2
Cell C2 has code 1
Cell E2 needs code 2

I know it should take an index/match function, but nothing I try is working. What I'm trying is the following formula in Cell E2 of sheet 2:

=INDEX('Sheet 1'!A:A,MATCH(C2,'Sheet 1"!E:E,0),5)

But all I get is no result. What's driving me bonkers is that if I copy everything over to a single sheet, that formula works fine.
