View 5 RepliesI am using Dev Express to develop a form in which i have a GridControl with a View inside a View.It looks like this:
I am then trying to use the event ValidatingEditor to validate the user input.I tried to do that by doing:
Private Sub grvObsAM_Artigos_ValidatingEditor(ByVal sender As Object, ByVal e As DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs) Handles grvObsAM_Artigos.ValidatingEditor
Dim row As Integer = Me.grvObsAM_Artigos.FocusedRowHandle
This, however always returns me something like -99999.. I poked around and tried this other solution using the sender from the event:
Private Sub grvObsAM_Artigos_ValidatingEditor(ByVal sender As Object, ByVal e As DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs) Handles grvObsAM_Artigos.ValidatingEditor
Dim grv As DevExpress.XtraGrid.Views.Grid.GridView = CType(sender, DevExpress.XtraGrid.Views.Grid.GridView)
Dim row As Integer = grv.FocusedRowHandle
And using this second solution i managed to get the focused row handle. Even though this worked this time (because the event was triggered by the view itself and i had access to the sender) this doesn't solve my problem as there are other events where the sender is not the view and the problem persists.Usign Me.grvObsAM_Artigos."insert anything here" doesn't seem to work properly.

View 1 RepliesI am creating a 2D RPG game similar to the pokemon interface. After solving my problem with walls, I came across another problem. If I make the panel show the whole map, it would be too small. Thus, I tried to increased the size to 1200,1200, but it wouldn't let me because my screen is smaller than that. Then I thought about it and realized that most games limit the sight of the map to the characters surroundings.

View 1 RepliesI have multiple textbox in a form. How do I know what textbox the cursor currently is? Trying to do something like this:
If TextBox2.Focus() = True Then
MessageBox.Show("its in two")

End If
But I think its not working.
I have my menustrip with the standard edit items. I know I can do this:
If TextBox1.Focused = True Then
TextBox1.Undo()
ElseIf TextBox2.Focused = True Then
TextBox2.Undo()
'Ect. Ect. Ect.
End If until I type out every textbox. However, I have like 30 textboxes and don't want to type out every textbox to see if they have focus. Is there a work around for that?

View 3 RepliesUsing DevExpress 10.2 within Visual Studio 2008 with VB.Net I have created a single gridcontrol that contains two different gridviews. The gridviews are related using an id column. Basically if there are related details about a row in the first gridview then the user can click on the plus sign to see all the related details. When I have any row on the first gridview I am able to get the focused row. Yet when I have the focus on any of the rows in the second gridview I am unable to get the focused row or the content of the row.

View 3 RepliesVisual Basic Interop Video Series This how-to video series is focused on the Interop Forms Toolkit and working with Visual Basic .NET and Visual Basic 6 together. The Interop Forms Toolkit allows Visual Basic developers to migrate their Visual Basic 6 applications over to .NET using a phased migration strategy. Instead of having to convert the entire VB6 application at once, the toolkit enables .NET Forms and User Controls to run directly in Visual Basic 6 applications so that you can build the pieces that you need over time.
Download the Code: Videos 13
You will need: Visual Studio and the Interop Forms Toolkit 2.0 in addition to Visual Basic 6.0

View 2 RepliesOverreaching amateur developer that is outsourcing some of my work and doing part of it as well. I've been working on a dictionary/ thesaurus / spell check & suggestion application that I am trying to get to work on all applications within the windows environment.
I've used hooking to get key stokes and show output as the person is typing for definitions and spelling suggestions. This isn't accomplishing everything I want. Works fine for spell checking and suggestions but to click on a word that already exists or for touch screen interfaces to touch a word it doesn't work.
I was reading the Raw Input API on MSDN and thought that would work but my developer that I've hired is advising me that the RAW input's scope is only on the window that has focus and so cannot do low level hooking. I'm considering giving the effort but wanted a 2nd third fourth perspective prior to making the effort.[URL]

Currently I have the following VB.NET code to make a screenshot of my desktop, but it only takes a picture of the active screen:
Public Function SaveScreen(ByVal theFile As String) As Boolean
Try
SendKeys.Send("%{PRTSC}")[code].....
The following code is how I execute the above function, if it makes any difference, which I don't think it does:
SaveScreen("C:Lexer_tracescreen.png")
Now, I need to be able to take a picture of the entire screen, not just the focused window.
When you do frmWhatever.showDiaglog(), frmWhatever stays on top of the calling form even if you click "behind" it. Is there any way to get this behavior on a form displayed by calling frmWhatever.show() ?
View 2 RepliesHere's my situation: I have a control with motion graphics (for the sake of simplicity, a 'video player' control) in my project. Think of a PictureBox with constantly-changing images. In front of this will sit a second control (such as a second PictureBox of the same dimensions). The topmost PictureBox will be drawn to in its Paint event.
I need to draw very few elements, and the bottom control is updated much more frequently than I need for this drawing. So these elements are drawn to the topmost control. Think of a news broadcast, where they have live video in the background, with a news channel logo, news ticker, and sometimes gradient visible in front.
I'm trying to create that 'foreground' control, and the closest I believe I have gotten so far is the following:
Imports System.Drawing
Imports System.Drawing.Imaging
Imports System.Drawing.Drawing2D
[CODE]...
The 'Opacity' property in the code above is a sort of "scaling factor." The image drawn to the top control may, in different parts of the image, have any alpha value from full transparent to a full 255. This 'Opacity' property is applied to the entire image being drawn, scaling the alpha values of each pixel.
