Use A Function In Vb Similar To Vlookup In Excel?
Jun 22, 2012
een using excel extensively. In excel I use vlookup function to connect and retrieve data from other workbooks. I want to know how I can do it in VB. So far I have created a form.The form has say three text boxes viz (i) A unique Number (ii) Name (iii) Address. I want that when I write the unique number in the text box for unique number the other two text boxes i.e. of Name and of Address should be auto populated. I have also established and tested the connection with the access database file using ADO.NET. I do not know whether I need to write an SQL or LINQ query for this purpose or I should write some codes. What should i do it and how should i do it?

I'm attempting to use the VLookup function to look up a raw score and convert it using an excel worksheet. However, instead of returning the figure in the lookup location, its returning the value that i'm looking up. For example, i'm looking up the number 5, it should give me the value of 63 but instead of returning the value 5.
xcApp = CreateObject("Excel.Application")
Excel1.OpenBook("testbook.xls")
xcWS = CType(xcWB.Worksheets("SOMATIC"), Excel.Worksheet)
MsgBox(xcApp.WorksheetFunction.VLookup(5, xcWS.Range("A2:F12"), 1, False))
EDIT: The above code DOES work, but it does not work with the following code(returns number i'm sending). One thing I did notice, it doesn't seem to be looping through all the Subnames...I just get one result and there are 10 in the TEMP table.
Connect()
sel("Select * from Temp")

I am trying to essentially convert an Excel spreadsheet into a Windows Form. On the first worksheet I have setup an IF statement to work as a search function =IF(C10="","",VLOOKUP(C10,'Price List'!$A$2:$D$40008,2,FALSE)) to read a price list on a separate worksheet. It works by taking a partnumber then puts the description in the next column (description column) and then the price in the "price each" column then finally totalling the row based of the quantity selected (see below).[code]...

I want share my working of excel and want to know its alternate on VB.The above attached snapshot is of an Excel sheet. While working in Excel, If somewhere I got the calculated "Voltage Drop" result like one of the cell of Column1.VLookUp function brought the rest Two columns entries in front of me.For example: If somewhere I got the result "0.22", VLookUp says "240" and "451".How can I get the same result while working with DataGridView in my project? The list is saved in Access Table and Connected to DataGridView1.And I want the "VLookUp" (or its alternate VB function) brings me the Matched or Like values to a TextBox1 and TextBox2 from Column "Size of Cables" and "Current Ratings".

If I'm not mistaken PHP crypt() function use DES-based encryption algorithm. So I've search DES Encryption code and all that I found is code that similar to the one in this post http://www.vbforums.com/showthread.php?t=471798
But with those codes I must enter 8 character lenght salt. Less then that the code wouldn't succeed. In the other hand. The PHP crypt() function only could use 2 character length salt. If you enter more than that, it seems it only use the first 2 character..[URL]

I want to pass a List of T where T is an object I've created that has about ten properties (strings, dates and integers).The lst passes to the function successfully. I am also passing an New T of the Object (itm as T).I can see all the values (see image below), but because it's generic I cannot seem to retrieve the property values and I cannot figure out how to iterate through the properties of each itm as they are retrieved in the For Each.[code]

I have a function in VBA that I need to convert into VB.net:Sub Crossfunction(ByVal Array1 As Decimal, ByVal Array2 as Decimal) As Boolean
Dim C As Variant
Dim Above as boolean
Array1 = Array(1, 2, 3, 4, 5, 6, 7, 8, 9)
Array2 = Array(1, 4, 3, 7, 5, 8, 7, 2, 9)
[Code]...
Is this the correct method? And how can I convert the function and not get an error: Error 1 Value of type 'System.Collections.Generic.List(Of Decimal)' cannot be converted to '1-dimensional array of System.Collections.Generic.List(Of Decimal)' when I redefine the Arrays as: ByVal Array1() as List(of Decimal),ByVal Array2() as List(of Decimal).

I have a vb.net function which uses oledb to create a spreadsheet, then treat it like a database, creating tables and inserting values. The function takes in a filename and a dataset, and returns the filename if it worked. The function works beautifully on my dev machine, but not other PCs. Below is my function, is there anything wrong with the code? EDIT: There are no errors being thrown, the resulting file doesn't contain any data.

I have an Excel VBA function that takes a number of optional parameters, including an optional Range:
Function DazBeta(A As Range, Z As Range, _
B As Integer, _
Optional Freq As Integer = 1, _
Optional c As Double = 0, _
Optional r As Range, _
Optional Pct As Boolean = True, _
Optional Label As Integer = 1)
I am translating to VB.NET, and it's the optional Range that is giving me grief because VB.NET does allow optional Ranges. Or rather, optional parameters must provide a default value. What is the recommended way to change the VB.NET function signature so that the code is callable from an Excel cell as a UDF? (The VB.NET implements a UDF, the assembly is registered as a COM server, and the Excel spreadsheet is told of this server and type library, allowing the VB.NET code to be called from an Excel spreadsheet cell.) I have other compilation problems, so I have not been able to explore this. I am thinking that accepting an optional Object (default value Nothing) might work and then I could cast the Object to a Range. Alternatively, if there were a default value that could be specified with an optional Range, that would work, too.

I want to make an numerical integration method with takes in an analytic function and integrate it over a specific interval. For the numerical integration procedure I want to use some procedures in nr.com. The problem is that these are programmed in C++ and they uses functors to pass a function to the integration method. How can I do this in VB 2010?
I want to initialize the function (i.e. set a=1,b=0 for function y(x)=a*x+b) and then pass the function to the integration method. Then when the integration method call the function it only calls the function with one parameter (i.e. x since a,b is already set)
What is the best way to do this in VB2010?I want to make a general integration method where I can pass any single valued function and integration limits.
I have just started using VB, and from what I have found so far it seems like the tools you have is
- to us a delegate for the function
- to use a lambda expression for the function
- send a pointer/adressOf
- to create a function class/structure and submit this to the function
As for now I am most inclined to create a function-class. But I am not really sure how.F.ex. I make different classes for each "uniqe function" I want to integrate, but how can I pass them to the integration function when I need to specify the argument type in the integration-function-call?This seems like a basic problem which applies to many Math operations, so I think it would be very useful to clarify this.

I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.
My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for
Here's my call:

I have a web site where users enter company names to use in the rest of the app. However, recently I've noticed that similar duplicates are appearing, e.g. someone will enter EastTec Solicitors another will enter EastTec Solicitors Ltd someone else will enter EastTec Solictors (missed the i out in Solicitors), when there should only be one entry of EastTec Solicitors. What is the best way of checking the database for entries similar to what they have entered? How would you about checking for spelling mistakes as well like the Solicitors one?
