I want to add a yes/no function to a message box (Are you sure you want to exit?) in InfoPath 2007. If the user clicks 'Yes' the InfoPath form closes, if no, then the user is taken back to the form. From what I have read this will not happen in InfoPath. So, I added a new windows form that has the Yes/No buttons.
For the 'No' button, I have (me.close) which closes the windows form and the user is left with the InfoPath form. when the user clicks 'Yes' meaning they want to close the windows form AND the InfoPath form. Below is my code so far.
Imports Microsoft.Office.InfoPath
Imports System
Imports System.Xml
Imports System.Xml.XPath

When retrieving rows from an SQL Server table I use the following code select mydate, Customer, Details from sales where mydatetime >= '" & format (somedate, "MMM d, yyyy h:mm:ss tt") & "'"This works fine unless the clients computers windows Region setting is 'English (New Zealand)'The default time format in windows Region and Language for New Zealand is [code]On computers with this region setting I get an SQL Error 'Conversion failed when converting date and/or time from character string'..If I manually select the other option for AM symbol, PM symbol in Region and Language i.e AM PM the all works fine again..What format string can I use so that above code always works, even if the Region time format is a.m. / p.m.

We have a large WinForms app, and there is a built-in bug reporting system that can be activated during testing via the F5 Key. I am capturing the F5 key with .Net's PreFilterMessage system. This works fine on the main forms, modal dialog boxes,etc.Unfortunately, the program also displays windows messageboxes when it needs to. When there is a bug with that, e.g., wrong text in the messagebox or it shouldn't be there, the messagefilter isn't executed at all when the messagebox is up! I realize I could fix it by either rewriting my own messagebox routine, or kicking off a separate thread that polls GetAsyncKeyState and calls the error reporter from there. However I was hoping for a method that was less of a hack. Here's code that manifests the problem:
Public Class Form1
Implements IMessageFilter
Private Sub Form1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles

There is String.Format function that is referred to in the documentation as the analog for Format function from VB6. There's also Format function from VisualBasic namespace that is provided for compatibility and basically has same powers as String.Format.Indeed, those two format dates and numbers.But VB6's function was also able to format strings:[code]String.Format is not able to do that, as far as I'm concerned, nor is the new Format. I also couldn't find any mention in the compatibility Format documentation that certain parts of VB6 functionality is lost, seems like the feature was deprecated "silently."Is there anything in the framework that can do this type of formatting?

The VB format() function has a bug in it that has existed for nearly 20 years! One would do this if communicating with devices that use fixed length HEX strings.
Ex: Something = Format(Hex(n), 00)
Note that the expected results occur when n = 0 to 255 EXCEPT when n=42 ... "00" is returned not "2A"! Truly an outright bug! VB up to and including .NET 2005 does this.
Testing in .NET 2010, it appears that now when a string is the passed value parameter, just the format string is echoed back.Not really fixed but functionality removed sometime between 2005 and 2010 versions.
Knowing this, I simply use my own wrapper function in all VB versions to do the formatting:
Something = PadLeftZeros( Hex(n), 2 )
Private Function PadLeftZeros(s As String, ByVal length As Integer) As String
' dumb function
To pad leading zeros to number string. Could be done many ways, this is just one primitive one.
Dim n As Integer
n = Len(s)
If n = length Then

I have a SQL function that I am calling in my VB.Net code within a display function. The SQL function will format my account data to include the following results form a Table. The table data: "001000011121" (this is the type of structure the data has before formatted)
So the data table data and vb Properties would be called Myaccount, HerAccount, ThisAccount. Once the data is pulled and then formatted in the VB.net code it will result into a GridDisplay as as: "001.00.001.1121"
The way I have my Public Function in my code is:
Public Funcion GetDisplay(_
ByVal dbBass as DataProvider_
,ByVal pps AS TMGDatarequestParms_
,By filter As IFilter_
) As Ilist
Dim strobe As String = CType(parms.OptionalParameters, DataProvider).Database
Dim sql As BiGSqlBuilder(TABLE)
sql.Select = String.Format("ID, [{0}].dbo.GLForamtAcct(Myaccount) AS [Myaccount], [{0}].dbo.GLFormatAccount(HerAccount) AS [HerAccount], [{0}].dbo.GLFormatAccount(ThisAccount) AS [ThisAccount]", strobe)
I left out some of the return code since not necessary. The only thing I'm concerned is how to format the SQL within the VB.net Code above.

I am trying to format a Function Code so that it returns a 4 digit result no matter the entry by the user (i.e. they enter 540, stores 0540 in the database). While looking online, I've found the format function, but when I use it, it returns 540, regardless if I enter 540 or 0540. [Code]

I have wrote a function which validates a masked exit box date format. I have entered into the Mask property 00/00/0000 which on screen translates to __/__/____, great. If I get an invalid date I want to clear the content and reset the focus back giving a message box warning. [code]It all seems to work until I then try to enter a new date. The first number a press seems to push the mask characters to the right and then the rest works. So if I entered 01/01/2009 I end up with _1/01/2009.

For years I never had trouble with this String. Format function until today when I got a value longer than 0 characters and the function returned all the characters in the string instead of just ten. Now sometimes I get less than ten characters so I can't use the substring with out getting an error. I can try the left function but I was hoping there was a solution with the Format function.

I recently moved a webservice VB.net project from VS 2005 to VS 2008 and now a conversion I use to create a unique receipt number is no longer working.
The Format() function which is supposedly a Visual basic function gives the error:
'Format' is a type and cannot be used as an expression.
The Year() Function which is also a VB function gives the error:
Name 'Year' is not declared.
The Datetime() Function which is also a VB function gives the error:
'DateTime' is a type and cannot be used as an expression.
The actual code statement remains unchanged between the two web services but VS2005 compiles and VS2008 does not.
Dim julda As Long = CLng(Format(Year(oneRowDon.Item(8)), "0000") _
+ Format(DateTime("d", CDate("01/01/" _
+ Format(Year(oneRowDon.Item(8)), "0000")), oneRowDon.Item(8)) _
+ 1, "000"))

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:
