I'm in a project where it's pretty much my first time doing all the architecture myself,and I'm running into a frustrating situation. My architecture for forms seems to be correct from a heuristic perspective, but I don't think its implementation is correct.
My architecture is thus:
Base Class: OrderForm
Child Classes: PurchaseOrder, Invoice, Credit

How can I assign a value to a message box for when the default value displayed in the text box is unchanged. ie. If my default value is 17 and the user clicks ok without retyping a number, the Input value displayed in a textbox will be 0.
Currently I have:
Public Class Form1
Dim MyValue As Double
Private Sub But_EnterInput_Click(sender As System.Object, e As System.EventArgs) Handles But_EnterInput.Click
MyValue = CDbl(InputBox("Input a value", "Data Input", "17", 200, 400))
[code]....
This works however if the user types 17, the textbox will read 0. not what i want.

Is there a way to disable the default members and methods inherited from the base class?
I made some classes in which elements like "Equals" and "ReferenceEquals" are confusing or I don't want them to show, or I have other methods providing similar functionality with different names and I don't want to override and use the default name.
limit the default events, properties and methods exposed from a UserControl so it only displays to the developer the new events etc that I code myself.What i mean is I have created a UserControl with a panel and 5 buttons, written 1 Public Eventonly at this stage, I have placed an instance of the control on a form in a new project, but in the drop down menu that comes up after say (myUserControl1.), there is a massive list of options, I don't want those to appear.

View 3 RepliesI am not sure how clear my question is by the title, but I am trying to make Class methods instead of Instance methods in Visual Basic that way I don't have to waste memory and code creating temporary objects to execute methods that don't need instance variables.
I am not sure if you can do that in VB but I know you can in Objective-C by using either a "+" or "-" sign in front of the method declaration. And in C++ (at least I think, I can't remember) you put the static keyword or const keyword in front of the function.How would I do this in VB if it is possible? Or should I just make a separate set of functions that are not members of a class?

View 5 RepliesIs it possible to set a project default for VB.NET winforms projects so that the default Modifier for controls added to winforms is Private (not Friend)?I know there's a "modifiers" property in the properties window so I can set it for each individual control however I would like to change the project so from now on myself and other developers have to specifically decide to change from friend to private. (Which I would strongly discourage them from doing).I believe there is no way of doing this, but on another forum a while ago someone mentioned it would be possible with an add-in (but didn't name the add-in or where to get it).

View 3 RepliesI have a main window with a datagrid in the upper half and a tabcontrol in the lower half. The datagrid contains a list of companies. One of the tabs of the lower tabcontrol contains the information about contact persons corresponding to the company selected in the upper datagrid.
On the tab I place a usercontrol.
<TabItem Name="pgContactsXCompany">
<local:ContactsXCompany x:Name="contactsXCompany"/>
</TabItem>

When I run the application everything works without errors. The Sap number of the selected company is passed to the function UpdateContactsXCompanyDatagrid correctly. The Me.dgContactsXCompanyList.DataContext seems to be assigned, but the contact persons' datagrid is EMPTY. No row is diplayed.
In vb.net (2008), I want to be able to control when a contextMenuStrip (context menu) is displayed. I don't want it to always appear when the right mouse button is clicked...only when certain criteria within my program are met. I figure I would use addHandler but I'm not exactly clear on how to completely control the opening of the contextMenuStrip. I know I would issue a call to the "open" method to render the contextMenuStrip. However, I am unclear as to how to completely take over control of when to render the contextMenuStrip.

I have a panel that is "drawn" on by passing: panel.CreateGraphics.GetHdc() into an api call
I was wondering how i can then clone what is now on that panel to another - i have tried: panel.DrawToBitmap and then painting the resulting image on the other panel - but this doesn't work
oh and also the panels may not be the same size ... so in this case the result would need to be "stretched" or "shrunk"

View 14 Repliesthe following data is not getting displayed in grid.....am using vb6.0
[Code]....
I have a datagridview with 3 displayed columns and 10 columns overall. If I run the program the gridview start with the first column visible and displayed. Now i want to scroll with the vertical scroll bar.
If i click on the "right" button of the scroll bar
my DataGridView1.Scroll - event
says:
DataGridView1.Columns(0).Displayed=True
DataGridView1.FirstDisplayedScrollingColumnIndex = 1
So this means "yes, the first Column is displayed but the first displayed Column is the second one!"
This doesn't make sense to me. Is there another opionion to this Problem, or is this just a small bug?

I am workinng on an aopplication using the DataGridView.My intent is that the DataGridView is displayed with four columns, the user clicks on a row in any column and the complete record for the selected item is displayed and the DataGridViewis no longer in view.
The code to do this is in the event "dgvCollections_CellContentClick" and the function works exactly as I want it to.The problem is that when I want to sort by a specific column I click on the column header and not only does it sort , it calls the 'CellContentClick' event and the details form is displayed, which I do not want to happen.Is there a way around this problem other then using the "dgvCollections_CellContentDoubleClick" event to select the detail? This was what I did as I sterted this project and I found that the double click was very sensitive and often did not work. The single click is much better for the eventual user.
I have been searching all over to find some code that will get the Project/Application's GUID. I can see it displayed in the Project Properties and I want to display it on the About Me page as well as use it to check for updates. So how do I get it via code?
