I have two form in my application i am calling two form together from master page.i wrote code in my master page
in top i declared like this
Dim form As New FrmDelivary
Dim frm1 As New FrmrecievedDelivaryRequest
in toolstrip menu event like this:
Dim frm1 As New FrmrecievedDelivaryRequest
frm1.Location = New Point(625, 225)
frm1.MdiParent = Me
frm1.Show()
Dim frm2 As New FrmDelivary
frm2.Location = New Point(965, 0)
frm2.MdiParent = Me
frm.show()
if i press R i want to go my cursor the particular textbox of FrmrecievedDelivaryRequest
if i press D i want to go my cursor the particular textbox of FrmDelivary
How can I do this? i trey something like this in frmMaster_KeyDown event: but same page is showing again. I have already open instance of FrmDelivary, so I don't want to show same page again. I want to just get cursor position to particular textbox of this form
If e.KeyCode = Keys.A Then
form.Show()
form.txtTicket.Focus()
Cursor.Position = form.txtTicket.Location
end if
I am working on vb.net windows application
After
frm1.Show()
place
frm1.txtTicket.Focus()
I don't think you need the Cursor.Position call
Set your frm1 and frm2 variables at the top of the code window so they are accessible from all of the Subs. In your KeyDown event, put
If e.KeyCode = Keys.A Then
frm1.Show()
frm1.txtTicket.Focus()
Cursor.Position = frm1.txtTicket.Location
end if
The problem is that you are instantiating a new copy of the form with the "AS NEW frmDelivery" statement.

I'm trying to use System.Windows.Automation to get to a UI element in VLC media player (specifically the status box in the left-most corner that shows the filename of the video currently being played). I can get the parent element and a sibling element but in Spy++ all of the elements that have a dimmed icon next to them I cannot reach in code... I'm assuming that dimmed icon means they are private or hidden or something like that. Here is an image showing what I mean:
Notice that I have a reference to the parent with the handle 0x30826, and I do a FindAll()* from that and end up with only one result, a reference to the child with the handle 0x30858. You can see in Spy++ there are 5 children of 0x30826, but only one of them, the one that I get when I do FindAll, has a fully black icon, the others have a gray icon and I cannot get to them. Notice also that the one I want is 0x20908 and it has a grey icon...
How can I get to this in code?
*This is the code I'm using to try to get all the children of 0x30826:
Dim aeDesktop As AutomationElement
Dim aeVLC As AutomationElement
Dim c As AutomationElementCollection
Dim cd As New AndCondition(New PropertyCondition(AutomationElement.IsEnabledProperty, True), New PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.StatusBar))
aeVLC = aeDesktop.FindFirst(TreeScope.Children, New PropertyCondition(AutomationElement.NameProperty, "got s01e01.avi - VLC media player"))
c = aeVLC.FindAll(TreeScope.Children, cd)
c = c(0).FindAll(TreeScope.Children, Condition.TrueCondition)
The first FindAll() gives me only 0x30826, which is fine because that's what I want, but the second FindAll, with no conditions specified, gives only 0x30858 when I can see that plus 4 others in Spy++, including the one that I want.
You are really handicapping your efforts by using Spy++ instead of the Inspect Program. Using Inspect, you can easily see that the target element is a text element parented to a status bar element that is parented to the main window element.
Using that information, getting a reference to the target text element is straight forward. Start by getting the main window, then its status bar and finally the first text element of the status bar.
' find the VLC process
Dim targets As Process() = Process.GetProcessesByName("vlc")
If targets.Length > 0 Then
' assume its the 1st process
Dim vlcMainWindowHandle As IntPtr = targets(0).MainWindowHandle
' release all processes obtained
For Each p As Process In targets
p.Dispose()
Next
' use vlcMainWindowHandle to get application window element
Dim vlcMain As AutomationElement = AutomationElement.FromHandle(vlcMainWindowHandle)
' get the statusbar
Dim getStatusBarCondition As Condition = New PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.StatusBar)
Dim statusBar As AutomationElement = vlcMain.FindFirst(TreeScope.Children, getStatusBarCondition)
' get the 1st textbox in the statusbar
Dim getTextBoxCondition As Condition = New PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Text)
Dim targetTextBox As AutomationElement = statusBar.FindFirst(TreeScope.Children, getTextBoxCondition)
' normally you use either a TextPattern.Pattern or ValuePattern.Pattern
' to obtain the text, but this textbox exposes neither and it uses the
' the Name property for the text.
Dim textYouWant As String = targetTextBox.Current.Name
End If
I am making a risk-type game for school that dynamically creates a 4x4 grid of buttons inside a table layout panel in visual basic. I have successfully created the panel and buttons with names that correspond to the row and column of the button. There are also two parallel arrays - one for button owner and the other for button number - that correspond to the owner of the button and the number of "armies" in the button. My issue is that when the user clicks a certain button, I need to reference the button name/value to know how many "armies" the button has to control the "attack" portion of the player's turn.
The following code creates the table layout panel and the buttons with names.
'Create table Dynamically
Dim ColCount As Integer = 4
Dim RowCount As Integer = 4
Dim f As New System.Drawing.Font("Arial", 15)
riskTable.AutoScroll = True
riskTable.Dock = DockStyle.Fill
riskTable.ColumnCount = ColCount
riskTable.RowCount = RowCount
For rowNo As Integer = 0 To riskTable.RowCount - 1
For columnNo As Integer = 0 To riskTable.ColumnCount - 1
Dim buttonname As String
buttonname = "B" & rowNo & columnNo
Dim button As Control = New Button
button.Size = New Size(179, 100)
button.Name = buttonname
button.Text = "1"
button.ForeColor = Color.White
button.Font = f
AddHandler button.Click, AddressOf buttonname_Click
riskTable.Controls.Add(button, columnNo, rowNo)
Next
Next
Me.Controls.Add(riskTable)
This is the dynamic event handler that I created. I tried using 'Me.Click' to get the name of the button, but it only returns the name of the form. I need to have code in here that references the name of the currently clicked button to then in turn reference the box owner and box number arrays.
Private Sub buttonname_Click(sender As Object, e As EventArgs) Handles Me.Click
MessageBox.Show(Me.Name)
End Sub
Any help would be greatly appreciated! I think that once I get this working, the rest of the game will be pretty simple to figure out.
Thanks!
Put the name in 'button.Tag' instead/also:
button.Tag = buttonname
Then it is easy to get the name with:
Private Sub buttonname_Click(sender As Object, e As EventArgs) Handles Me.Click
Dim result As String = CType(CType(sender, System.Windows.Forms.Button).Tag, String)
End Sub
(Check the System.Windows.Forms.Button though, might need some tweak to match your buttons inside the table. riskTable.Controls.button ?)
Background:
Entry is via a subform for adding/showing/linking images.
I do not want to store the image files within my DB, the image folder is separate. The DB will grow rather large in time.
I have created a click-control enabling a popup for user to browse and click on the imagePATH to be added in a Bound Textfield (called Bildadress, no not misspelled in My country, Grin ) in the subform.
See code below.
Then I add a new unbound Image-control and specify its Controlsource = the Textfield mentioned above.
For the firs image this works wonderful, but for the following the Image-control returns NULL (not show att all). The data in the Textfield updates as it should.
Will the 2nd stage only work in a 1:1 relationship OR can I (with your help) use VBA code to make this work?
OPTIMAL would be to get this to work and also a 2nd Bound Textfield just displaying the actual image file name. .
I hope someone out there have encountered this problem who also didnt want to use Attachment to store the files within the databae.
CODE:
Private Sub AddFilePath_Click()
Call Selectfile
End Sub
Public Function Selectfile() As String
Dim Fd As FileDialog
Set Fd = Application.FileDialog(msoFileDialogOpen)
With Fd
.AllowMultiSelect = False
.Title = "Välj önskad fil"
If .Show = True Then
Selectfile = .SelectedItems(1)
Me.Bildadress = Selectfile
Else
Exit Function
End If
End With
Set Fd = Nothing
End Function
If you use a bound textbox that holds the image-path then you can use
Me.Imagecontrol.Picture = Me.BoundTextControl.Value
to load the picture into an unbound image control. In your case that would be something like
If .Show = True Then
Me.Bildadress.value = .SelectedItems(1)
Me.Bild.Picture = Me.Bildadress.value
Else
It would be best to also load the respective picture in the OnCurrent Event.
Private Sub Form_Current()
Me.Bild.Picture = Me.Bildadress.value
End Sub
However, keep in mind that access is a one-file-database and you break that paradigm when using links to external files where the files would belong into the DB.
i'm using the mshtml.tlb for loading/parsing html and i'd like extend it for clicking elements by code. the problem is trapping the loading-process after eg. a button was clicked.
in my specific case i'd like to perform a user-login.
here's my code:
Dim WithEvents m_doc As HTMLDocument
' load page
Set m_docNU = New HTMLDocument
Set m_doc = m_docNU.createDocumentFromUrl(m_url, vbNullString)
Do While m_doc.readyState = "loading" Or m_doc.readyState = "interactive"
DoEvents
Loop
set txtUsername = m_doc.getElementById("username")
set txtPasswort = m_doc.getElementById("passwort")
set myButton = m_doc.getElementById("submit")
myButton.click
now here's the big question mark: how to continue vb6- like "wait until page is loaded"?
i've tried as above using a do while-loop and checking the readyState, but for some reason the readyState doesn't change after clicking the button ..
any ideas?
thanks
ps: is there a more elegant way instead of the do while-loop? eg. using a progressbar?
use vb.net
wBrowser is a webbroser object
While wBrowser.ReadyState <> WebBrowserReadyState.Complete
Application.DoEvents()
End While
i have written some Macros for Visio. Now I copied these to a Stencil called Macros.vss
How can I call my Macros now?
It all depends on what the macros do and how you'd like to call them. I'm going to assume they're simply macros that will execute something within the active Visio page.
By default in Visio VBA, any public subs with no arguments get added to the Visio Tools->Macros menu, in a folder named by the document holding the macros (in this case Macros) and then separated into folders by module name. If you're the only person using the macros then you probably don't need to do anything else.
However, since you put them in a vss file I'll assume you'd like to distribute them to other people.
There's something funny (and by funny I mean irritating) about Visio and how toolbars and buttons work, when added programmatically. Unfortunately, when you create a toolbar using the UIObject and Toolbar and ToolbarItem classes, Visio is going to assume the code you're calling resides in the active drawing, and cannot be in a stencil. So I can give you a little guidance on using those classes, but basically it consists of distributing a .vst template along with your .vss files, with just a single required sub in the .vst file.
So, instead of using a custom toolbar, you can attach code to shape masters in your .vss file that execute the code when they get dropped on a drawing document (using CALLTHIS and the EventDrop event in the shapesheet). With this method I just have a sub that gets called using callthis that takes a shape object as an argument, executes some code, then deletes the shape (if I don't want it around anymore).
And lastly, you can manipulate the Visio UI programmatically to add a toolbar and buttons for your macros. Below is some sample code, basically the way I do it with a solution I developed. As I mentioned above, the most important part of using this method is to have a document template (.vst) that holds a sub (with the below code it must be named RunStencilMacro) that takes a string as an argument. This string should be the "DocumentName.ModuleName.SubName". This sub must take the DocumentName out of the string, and get a Document object handle to that document. Then it must do ExecuteLine on that document with the ModuleName.SubName portion. You'll have to step through the code and figure some things out, but once you get the hang of what's going on it should make sense.
I'm not sure of any other ways to execute the macros interactively with VBA. I think exe and COM addons may not have this issue with toolbars...
