Within Control Panel -> Regional and Language Options, there is a Formats tab, with a drop down of all possible language formats. I wish to retrieve this list using VB.NET. Could anyone point in the direction of which Windows API call to use?
View 2 RepliesUsing OLE and Jet, you may receive errors when saving system dates and times to databases in different regions.Consider what happens when saving dates and times returned using the Now() function in Canada or the US: the date string "#2010/02/03 08:59 AM#" will save fine. If using 24 hour time, the string "#2010/02/03 08:59#" will also save fine.
If you change your system region to Spanish (Peru) or Spanish (Mexico), the ante meridiem changes from "AM" to "a.m." (or "p.m."). The date string becomes: "#2010/02/03 08:59 a.m.#"Note that this will NOT save correctly to the database and throw a System.Data.OleDb.OleDbException. The workaround we use is: Public Function clean_date(ByVal strDate As String) As String Dim str_buffer As String

I'm running Microsoft Visual Basic 2010 Express on Windows 7, using a Regional Setting set to New Zealand.
When I enter a date in a NZ format (d/mm/yyyy), the IDE highlights the date and tooltip reports date constant not valid. But it is valid for NZ! Meanwhile, the IDE happily accepts dates in the US format.
I would have expected VB to look at my PCs regional settings and set this as the default format. What is wrong here? I have reinstalled the application, but still have the same problem.
Actually I am a basic user, but I like to utilize the sources around me to solve my problems and one of those sources my little knowledge about VB.Net. Today, I am forced to do some changes in the regional setting i.e. Format, Standard Digits & Native digits "Shot attached" many times a day for printing purpose through an ERP system. Therefore, I need to read the current setting for those options and two buttons (one to change them, the other to restore the previous setting).

How to display the controls in the format on the left (new windows format)
example: inside regional date format setting i set "Short date format dd/MMM/yyyy" and inside vb.net program i set "strSQL = strSQL & ",'" & Date(Date.Now.ToString("dd/MM/yyyy")) & "'" ----> working fine. if user changed the regional date format setting to other format like "mm/dd/yy" facing problem during saving record into sql table. error date conversion. It's possible to avoid using computer regional date format from vb.net? or have any other way...

I have a BindingList of transactions that I am binding to a DataGridView. The client now wants each row to have a sequential number. (1,2,3, etc).There could be hundreds of transactions. So is there an efficient way to assign a sequential number to each item in the bindingList?I know I could For/Next through and manually assign an incrementing index. But I am concerned about the performance when we process lots of transations.

I have a small requirement and that is as follows:
I am populating a ListBox using stored procedures and the ListBox is populated as follows:
lstItems.DisplayMember = "emp_name"
lstItems.ValueMember = "login_id"
lstItems.DataSource = accessFunction.getEmployees
The ListBox gets populated correctly. After it is populated, i have a CommandButton and on the click event of the button, i want to remove selected items from the ListBox. So in the click event of the CommandButton, i have written the following code:
lstItems.Items.Remove(lstItems.SelectedItem)
After selecting an item from the ListBox and when i click the CommandButton, i get an error as "Items collection cannot be modified when the DataSource property is set".
how i can delete items from the ListBox.

View 6 Repliesi am working on a college project in visual basic 2010. in my program, i noticed at the last minute that i needed to add a "main" window. in this main window, i want to have all my other forms opened by buttons (i know how to do that part of it).
the problem i keep having is the window with the options to save the information pops up, not the main window. is there a way to easily fix this? maybe a snippet of code, because the only way i can think of is to scrap the project, start over from scratch adding my main window first, then the others.
im not 100% sure this is the right place for this, but thought I'd give it a shot.I created a windows service, and it accepts startup parameters to set the connection string for my database connection. (-L for live, -D for dev, -S for stage etc.)[code]I installed the service using installutil (I already tried using sc.exe) and I can't specify startup parameters.So if I go into Services and go into my service properties and manually type -D into the Startup Parameters box and hit start, I get -D as my parameter, life is good. But the parameter won't save in the startup parameters box, it just reverts to a blank box whenever I close the properties page.[code]

What are best practices when creating a custom event log for a windows service? I've set my service on a timer so it fires up every day (except weekends) at the same time. For the last 3 days, I've been getting the following error: The source 'DMCS57ExportService' is not registered in log 'DMC S57 Export Log'. (It is registered in log 'DMCS57ExportLog'.) " The Source and Log properties must be matched, or you may set Log to the empty string, and it will automatically be matched to the Source property.Based on that error, I know there's something wrong with the code that creates the custom event log (see below)

View 1 RepliesDows anyone know how I can build a timeout feature into a windows forms app.
The app is event driven, but I am thinking of somehow using a timer which counts down for say 10minutes, and one the timer ticks then we time out the user.
The problem I have is how can I reset the timer each time the mouse is moved or clicked.
This has been driving me batty for the last while. I have an application that is passing up data to a SQL server table. Part of the data is dates. Because of settings on the SQL server the update will not accept the MM/dd/yyyy format. I have been trying for quite some time to get around this.
For some more information. Changing the update method or the server regional settings is not an option and I don't want to change my regional settings as this may not reflect the production server when this goes live.
Here is what I have tried so far
Code:
Dim dateEnd As Date = Date.MinValue
Dim dateStart As Date = Date.MinValue
If IsDate(Me.txtPostEnd.Text) Then

It works fine if the day is 12 or below because it still thinks that is the month. Is there a way to force the code to recogize that I want to use dd/MM/yyyy format or even dd/MMM/yyyy format?
This has to be done at thhe vb code side as the update to the SQL server is completed via a custom framework so I can't customize the SQL code to insert the data using a CONVERT
I do not live in USA, and my program run specifically with my country's Regional and Language Option format. However, many Windows XP, Vista and 7 installed in my client computers automatically with English (United States) Regional and Language option. I want my program to automatically change the computer regional and language option to my country. However, I do not find anyway to do that (changing the computer regional and language option in runtime by the program), yet.
View 11 RepliesIs it possible with VB .NET to make the program use specific regional settings? More precisely , I want to make my application always use the English regional settings (those defined from Control panel > Regional settings) in order to always use (and calculate) the decimal numbers by using the dot symbol ( . ) as decimal separator , regardless the settings on the current PC (in order to avoid forcing the user to change his Regional settings) ?
View 7 RepliesI've searched around but can't find a clear answer for this. From my winforms VB2010 app, I'd like to be able to detect the country of the user's PC at runtime. Specifically, all I really need to detect is whether the user is in Australia or Canada.Most things I've seen will say "have a look at System.Globalization.CultureInfo", but with no clear example. I also know that the old-school "GetLocaleInfo" API can be used for this as well. I do have some code using the latter, which detects Australia when LOCALE_ICOUNTRY returns a value of 61. However, that won't work for Canada, as it returns 1, which is the same as USA (I know that these are based on telephone country codes).

Now I realise that you can't use the above functions to find parts of Windows but it just gives you the idea. If I could do it with API functions that would be fine otherwise I am a little bit limited because I am using a Visual Basic scripting type engine which I won't bore you with details of.
