I have a DataGridView bound to a DataTable in a DataSet.I set all columns of the DataTable to System.Double.I want the last row of the DataGridView to display "PASS" or "FAIL" depending on some condition of the values in that column.How do I do this?
Ideas: lastCell = IIF(condition, Double.PositiveInfinity, Double.NegativeInfinity) Then, apply some conditional formatting (Inf -> PASS, -Inf -> FAIL) to the final row of the DataGridView.

I am using the DateTimePicker control in a Vb.Net Windows project.I would like the date to reflect the Regional Settings on the user's computer, but also to show the month name, rather than the month number.For example, if my computer is set to English(US), I would like to see Nov 26 2009, and if my computer is set to English (NZ), I would like to see 26 Nov 2009Is this possible?

I'm having a bit of an issue getting the number formatting of VB .NET 3.5 to work just right for me. I have to convert numbers to scientific notation, with 2 digits for the exponent and 6 digits after the decimal. I've been able to get this for numbers that have enough digits, but for other numbers, it truncates the number to use as few digits as possible. For example, I would like 0 to be converted to 0.000000e00, or 123.4 to be 1.234000e02.
I know that you can create custom formats for the DateTimePicker control, and I've googled this but is there any way that you can allow a user to only select Sunday dates in a Month with this control?
I want to save a Custom DateTimePicker.Value in my Application Settings. The custom format is : dd/MM/yyyy hh:mm:ss, instead of dd/MM/yyyy The field i've created in the application settings parameters is LASTSAVE (DATE / APPLICATION)
When I try to link in the ApplicationSettings/PropertyBinding ... VALUE with my field LASTSAVE, i have an error :
The Value '01/01/0001 00:00:00' is not valid for 'Value'. 'Value' mustbe ... 'MinDate' et 'MaxDate'.
Name of the parameter : Value
I then entered the MIN and MAX date in the properties of my control DATETIMEPICKER. I have also put into the properties Value a start date like 23/11/2011 12:00:00 ;
However, when i retry to link in the ApplicationSettings/PropertyBinding ... value to LASTSAVE / I have the same error (The Value '01/01/0001 00:00:00' is not valid for 'Value'. ). I've saved all, do a process that put a value in the datetimepicker.value, but it's not saved, cause not linked.

In my app I present to the user an option to customize the name of the file that gets produced. The format string the program reads is something like "yyyyMMdd-%1-%2-%3-%4" which the user can customize to his liking. In this case the format of the date is yyyyMMdd and the %1 is the trip number like 1000P, %2 is the origin code like PTTTT, %3 is the destination code like PHYUD, and %4 is a secondary stop code like YYYY123. I'm having problems taking the actual data and formatting into the custom string. I believe its the date format that I'm getting stuck on.
So far I have sOut = txtFormatPattern.Text sOut = sOut.Replace("%1", "1000P") sOut = sOut.Replace("%2", "PTTTT") sOut = sOut.Replace("%3", "PHYUD") sOut = sOut.Replace("%4", "YYYY123") sOut = myDate.ToString(sOut) 'date is July 01, 2007
The output is "20070701-#1000P-PTTTTP12YUD (YYYY123)"
The problem obviously here is my last conversion. The string contains key characters that denote a part of the date specifically in PHYUD. So my question is how can I give my user the flexibility to format the output as they wish and then convert that properly?
I'm trying to alter the existing number formatting in my company's application to make it more readable for international users. This is a stock trading application, so most stock prices come in with numbers precise to 2 decimal points, like so-> 17.23 We could also get ticks in that have precision out to 4 decimal points, so a penny stock might be 0.0341. The original string format that we were using for stocks was "#,##0.00##" Which would give us the format we wanted (essentially trimming '0's). The problem here is the ',' and '.' are forced onto the user, where in many other countries the thousands separator is '.' and the decimal point is ','. Boss man doesn't want to use "N4" for all numbers, even though this would resolve the globalization issue. Is it possible to have a globalized custom string format?
Other options besides writing some middle man code to internationalize numbers formatted the original way or another string.format method?
I have a custom collection class that is bound to a data grid view object.I'd like to try to do the following from the custom element class if possible.
1) I'd like the name of the column header to be a different text than the name of the public property in the custom class. i.e. Trade_Name should read "Trade Name"
2) I'd like to try to be able to manipulate the text formatting/color of the individual collection class element's items. i.e. for a profit/loss field I'd like to have the numbers be red if they are loss and black of they are profit. I know I could do this from the datagridview object in the form, but that can be cumbersome to raise events etc.
I have some VB .NET software that interfaces to a load of old (but sound) COM objects. The VB provides a GUI for the COM objects, part of which consists of setting various options on the COM objects - several of which relate to string formatting.I have a simple pair of VB .NET functions that convert basic %f, %d, %g formats to/from .NET equivalents using a large select case covering specific common strings, but they don't cover all formats.[code]Before I start diving in and making it more versatile with some parsing, does anyone know of a class (eg VB or C# .NET) that provides a decent ready-made implementation? Or perhaps some regexp wizadry could be used?
While I understand there are properties of MailItem that would allow one to programmatically create a formatted email, I would prefer the ability to copy the body of an email that is already formatted to my liking (bolding, italicizing, embedded pictures/tables, set margins, etc.) copy and paste it to a newly composed email such that this formatting is preserved.
This is what I would like to achieve:To create a custom messagebox, with varying number of buttons with custom .Text descriptions, and other features. I intended to have a property array that would be redim-ed and have values (.Text values) set by the calling class:
I came across this great article on creating a custom datagridview column which creates a graph-like effect in the cells of a custom datagridview column:[URL]..Does anyone know how you would edit this to format the number in the cell as a percentage? And does anyone know how you would set this up to take 0 values which do not create any graph effects at all.I have been trying to do this but keep getting errors.
I was trying to block the closing of a custom combo box popup window in my custom DataGrid. The popup window comes by pressing F4 or ALT+DOWN keys in my datagrid which is getting closed if I press the down arrow for the first time, after showing the first value in the combo box as selected. Next time onwards, if I press the F4 key and down arrow, I can move to any item in the popup window and select the item using keyboard and in that case, the popup window is not getting closed till I press the ENTER key or selection using the Mouse. Is there any specific reason for this behaviour or something is missing in my code part? [code]...

I'm using custom serialization and when the xml is generated it's putting the class name as the root element
Example:
<MyClassName> <MyIntendedRootNode> <ObjectType>
[code]....
I'm invoking the serialization by calling xmlserializer.Serialize(writer,Me) so I'm sure that has something to do with it.I've tried putting XMLRoot onto the class, but I think as vb is compiling this partial class with its aspx page, it's either overwriting this property or ignoring it entirely.I'd like to just tell it to either throw away everything it has and use a different root element.
I have a Custom Principal class that Implements System.Security.Principal.IPrincipal and a Custom Identity class that Implements System.Security.Principal.IIdentity. So when a user successfully login to my windows form application, I set My.User.CurrentPrincipal = CustomPrincipal, which worked great until I started adding custom functions to my Principal and Identity classes.

I have a custom SiteMapProvider (populated from database) and a custom AuthorizeAttribute (validates current users roles + requested page against Role_Page database) for controller classes.I have to implement the function SiteMapProvider.IsAccessibleToUser(context, node). I also have to implement AuthorizeAttribute.AuthorizeCore(context).How are these two functions related? Isn't there some way to 'attribute' the SiteMapProvider?
Some code:
edit: Might this be a solution (inside AuthorizeCore())? context however is HttpContextBase, and IsAccessibleToUser() only takes HttpContext as parameter.If Not SiteMap.Provider.IsAccessibleToUser(context, SiteMap.CurrentNode) Then
current code:
Public Class CustomValidateAuthorization : Inherits AuthorizeAttribute Public Sub New() End Sub
