I am using Visual Basic.Net 2003 and have a DataGrid in the form that I am using but I can't find anuindication or procedure to add a vertical ScrollBar.
Any way to apply some validation rules to the following code? VB Private Sub dgOperator_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles dgOperator.EditingControlShowing Const cSUBNAME As String = "dg_EditingControlShowing" [Code] ..... Another thing should I be applying this validation on the Id Op'rateur column or when I click to the edit the next column in the datagrid i.e. Description?
I have an VB.Net ASP page that I have a datagrid on it with 5 columns and a few rows of data. The page will show the data and grid just fine. I need to now apply alignment to the datagrid columns. dgLast5Bills.DataSource = dtBill dgLast5Bills.DataBind() dgLast5Bills.Columns(0).ItemStyle.HorizontalAlign = HorizontalAlign.Center The code above will error out when it hits the line for the alignment.
I have written a converter class(implementing IValueConverter) which converts a code that comes from the database (for example "CTY") into a more user friendly description (for example "City"). I want to use the converter on a single Column in my XCeed WPF Datagridcontrol, but I do not know to which property I must set the Converter to. I also tried to attach it to a DataCell using a style but it won't work properly and I think it is also not necessary since the converter should apply to only one column and not every cell.The columns are also autogenerated so if I could apply it at runtime, that would be awesome!I don't know to which property of the column I must aplly the converter to (the Xceed Column doens't have a "Binding" property. Do you guys have any suggestions?More examples or code can be provided if asked for. I hope my problem is a bit clear for you.EDIT:
This are the things I use in my XAML file: <utils:BudgettaireEntiteitConverter x:Key="BudgettaireEntiteitConverter" /> <xcdg:DataGridCollectionViewSource x:Key="GridViewSourceDefault"
So with the stock Textbox, I set the Scrollbars property to Vertical. This is great if the text in my box never changes; I can scroll up and down while the box sits still. If I'm running a background operation that logs output to the box though, the scrollbar resets itself to the top every time I append text to the box.
I know I can set the Textbox.Selection property (or use the Select method) to reposition the carat in the textbox, make note of that position in a variable, then append text, reset the carat, and use the ScrollToCarat method to reposition the scrollbar where it belongs. That's a really (ridiculously) long way around. Anybody know if there's another/better way of holding the scrollbar position, short of actually building a custom control (or using a Textbox and a separate Scrollbar)? It never hurts to try. In a worst case scenario, you'll learn from it.
I am just staring off using VB 2010 after using 2005 for a while. In 2005 I used a third party control to automatically make a button a default color and when the mouse rolled over it, it changed to another color and then back to the original color when the mouse left the button.
I want to be able to set this as a default for all of my buttons in my project as there are tons of buttons throughout. I found the ControlTemplate. I don't know if it is the answer or if I don't understand how it works, but I just am not getting it.
I need to do this in order to create a dynamic background brush for a custom control (inherits ContentControl). My custom control has two dependency properties: StartColor and EndColor. In the control template for the custom control, the control is wrapped in a border that's background is a RadialGradientBrush with gradient stops. one gradient stop's color is bound to StartColor and the other's is bound to EndColor. I have this WORKING in XAML, but I need to convert it to VB code. The border element of the control template in XAML is done with the following code:
I have inherited support for a program written in VB2008
The problem I have is as follows:
Users have a low screen resolution (company policy) and so can't see the bottom of a particular form.
The bottom of the form has buttons that allow them to navigate between its' four pages so they need to be able to see them. This being the case I need to add a scrollbar to the form.
If I try to drag and drop a vscrollbar from the toolbox it just sits there at runtime (you can slide the button on the toolbar up and down but nothing happens regarding scrolling the page.
All the reading I have done seems to point to forms being given scrollbars in accordance to the AutoScroll, AutoScrollMargin and AutoscrollMinSize properties of the Form itself.
By setting these properties I can get scrollbars to appear in the IDE but they are not there at runtime.
I think I'm probably missing something really obvious here but, so far, have been unable to work out what it is.
So, in my vertical scrollbar, the maximum value is 16. In my application, I made a Label to track the scrollbar's value, just for testing purposes. I noticed that when I move the bar to the bottom, the value is 6. And when a [i]release[/i] the button (stop holding it with the mouse), the value becomes 7. Something similar goes when I move the button to the top: It is 1, and when I release the button, it becomes 0. That's a bit weird, but what mainly bugs me is why I cannot reach value 16?
I code GUIs in .NET frequently, and most of them only have the value of being a GUI, e.g. they don't do anything otherwise impossible. So most of the development goes to making them friendly, intuitive and eye-candy.Then it comes to my mind it would be simply amazing to skin them through .msstyles files, since there are so many places to find those files, and also tools to make your own.And some of those msstyles are just stunning, probably not for your whole desktop, but for styling homemade apps it would be perfect.
i have one quetion maybe some of you know codejock skinframework witch allows you to apply a skin to your vb6 application and i thought about asking is there a way applying a xp/vista theme to an vb .net application i dont want to use xp style if you think like that i mean downloading a skin and applying it only to my application? is that possible in vb .net
I create some vscrollbars dynamically and add scroll event handlers to them. I really want to detect when the user has finished scrolling with a mouse up event but this doesn't seem to be part of the scrollbar events.
I have a small VB.NET application built using VS 2008 and .NET 3.5.Very simply, there is a timer that kicks off every few seconds to download an XML stream from the web. I look at this stream and manipulate it.The problem I am facing is that the remote web server may not respond in a timely fashion to the following line of

How can I implement asynchronous calls so that the my application can behave without locking up?
I have a 2d array and I want to do a calculation on each element in the array and then return the index which results in the smallest value.
I have tried iterating through each element in the 2d array and running the calculation. If the calculated result is smaller than the currently stored minimum I set that to the minimum.
This works but it runs so slowly it makes the solution a non starter. It performs each calculation quickly but because of the number of elements in the array the calculation for the whole array is stupidly long.
Is there a way to apply any changes made to an entire application and not just the open (active) form that you are in? I.E. I change the backcolor to a color from a color dialog. I want that chosen color to be applied to all the forms' backcolor in my project. Can this also then be applied to all the other controls' backcolor? The code that I posted works but all forms and controls have to have the changes applied to each one separately.
So i want to apply gradient to a square, a center to edges gradient. This is the code:
Public Class Form1 Private Sub PicSourcefrm(ByVal sender As System.Object, ByVal e As PaintEventArgs) Handles Me.Paint Dim Graph As Graphics
[Code].....
NOTE: Picsource is just a PictureBox named that way. If I put "BrushSquare.SurroundColors = Color.Red" in a comment. The program works but the edges are white, not red like I want them to be.
i have a tab control thing and i want to make it transparent. When i set each tab to that is just turns gray, even when i run it. Can someone help me. I dont want to have to apply the same image to each tab several times.
I just want to verify something. I believe it is likely that if I apply the using command to a SqlDataReader, that it will both close the data reader and dispose of it. For example:
Using sdr As SqlDataReader = cm.ExecuteReader() Dim someInt As Integer = sdr.GetInt32(0) 'other details and actions End Using
Will that close the sdr SqlDataReader after it exits the Using code block. (I believe it will, but just want to verify.)

I have got some XML which is built by my application. This XML is dropped to an XML file, which I then wish to apply an XSL stylesheet to in order to convert it to a HTML page. However, every time, it just keeps coming out with the original XML rather than the transformed HTML
