Does anybody know what is the equivalent of findwindow or findwindex in vb.net. Here is what I am trying to do. I am reading a Real Time Adherence window that is dynamic(assumption) and is constantly refreshing. I have tried Findwindow and Findwindowex although I am able to get to the MDIclient and then to the window there is no "edit" field for me to read off. I have tried Spy++ and it also sees it but it does not have an available control for me to read the information.
I am developing an application that reads an MDI applications child window and grabs the information from a control such as a textbox or listbox. I have tried to use Findwindow in order to accomplish this. I have gotten all the way to the control, but once I get there it returns blank. Can anyone point me in the right direction to accomplish this.I am able to read the window title and get the control title but when I send a message to the window it returns 0. Now I am just experimenting so I have no concrete code, but here is a snippet.
All 3 labels are named the same. The one i am most interested in is a progress % counter (1%, 2%, 3%, etc..)How can i get the value (using a timer of course) from that label without knowing the caption of it at any given time?
I got this little app that I'm working on and it involves the browser but I cant seem to get a hold of it.Now here is the thing, I tried going level by level, but the thing is that every time I run my program it changes :S So how can I actually get a hold of "Internet Explorer_Server"..
I am using MS Windows XP, and Visual Basic Express 2008 and I am trying to write a programme that will enter a lot of information into another programme that I have written for testing purposes. The programme that I am writing to has up to 500 line items, by 10 possible suppliers; as you can imagine testing this every time is too labour intensive.[code].....
This code correctly takes me through the various forms until it reaches the Input General Information Form, which opens with the top TextBox in focus. However the entry, "Escravos Gas to Liquids", is placed in the last TextBox.How do I make it enter in the first TextBox, which is in focus? From that point on how do I cycle through the remaining 10 TexBoxes to make each entry?
I am trying to send a keystroke to a running powerpoint presentation with SendMessage or Postmessage. But I can't get as far as the handle for the presentation.

As I understand it, you have to use FindWindow to get the application's handle and then FindWindowEx to get the sub-window's handle. The problem is that the line below FAIL returns 0, not a handle.Relevant material / possible answers are given in these sites but in C-type languages and I just can't see how what I'm doing is making the code fail: RE: hide cursor for kiosk application (powerpoint) hide cursor for kiosk application (powerpoint) | keyongtech Passing Event to Other Application.
I've been using the FindWindow API for some time now, and it seems as if the function opts for an Windows Explorer window before any other window with the same window title.
For example, if you have a folder named Calulator open, along with the Calculator application built into Windows, FindWindow will return the handle to the folder every time.
I just thought this was an interesting occurrence, and I was wondering whether anyone knew if this is the case every time (an Explorer window over any other window) when using the FindWindow API.
I've been trying to use the FindWindowA api and also the FindWindowEx api in a little VB.NET 3.5 app and it doesn't appear to work. I get a positive long value returned whether I have an open window with the correct title or not. Anyone else noticed this?
Am trying to detect if a window is running, the result always returns a rather large number instead of 0 and I'm not sure why. All documentation I've read states this is right.
Private Declare Function FindWindow Lib "user32.dll" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long Dim ClassName As String = vbNullString Dim WindowName As String = "some fake window"

but is there a way to search for a single process without using a For statement?
I just can't seem to get this right, what I'm trying to do is use FindWindow to find the windows of more than one window. Here is the code:
app_hwnd = FindWindow(vbNullString, CheckedListBox.CheckedItems)The thing is, if I use .SelectedItem, it only finds one window and if i use CheckedItems/SelectedItems it gives me an error: "Value of type 'System.Windows.Forms.ListBox.SelectedObjectCollection' cannot be converted to 'String'."
So right now, I'm confined to using FindWindow for only one window--when I want to do it for more than one window.
I need to send two keys (" " and {Enter}) to a security warning in an Acrobat Window from a VB.NET application. Here is the function I use :
Private Sub SendAcroKey() Dim HWND As IntPtr HWND = FindWindow("Adobe Acrobat", vbNullString)
[Code]....
But I can't get FindWindow() to work properly, it always returns "0". I guess I'm not giving the good parameters, lpClassName and lpWindowName, but I dont now how to get the right ones. So here is the question : How can I know the lpClassName and lpWindowName of a security warning in Adobe Acrobat 7 professional ???
I really have to work this out but theres not much information on the web about those function, even on MSDN.
Public Class Form1 Private Shared Function FindWindow( _ ByVal lpClassName As String, _ ByVal lpWindowName As String) As IntPtr End Function '.... End Class
My question, what value should be passed into Function FindWindow(lpClassName, vbnullstring)? Can I use "Form1"?
I have spent the last 3 hours trying to figure this out with no success:The WIndows XP phone dialer has a "Hide Calls" available from the context menu, can someone run Spy++ (or similar) over it and let me know what message i should be looking out for to fire the "hide calls" option. Also, do i send it to the child ("Preview") or the parent ("Phone Dialer")
This same (Identical ) code works well in another program but does not in windows service... Returns 0 for window handle ...?

I am using VB Express 2008, on Windows XP Pro. I have written a programme which tests another programme which compares prices and terms from several vendors. This Bid Tabulation programme, compares prices and terms of up to 10 Bidders and 500 line items in mixed currencies.The testing programme, initially, would not work and I discovered that I needed to introduce a delay in order for it to run the Bid Tabulation programme. So my initial code, using the delay, was:
[code]...
And the button was clicked, and the Bid Tabulation programme started and ran successfully, as long as the number of vendors was 5 and the number of line items was 5. when I tried to increase the number of vendors to 10, the programme failed.I then discovered that at the point of failure, when the particular ParentHWND=0, if I introduced:
[code]...
Does anyone know what I am doing wrong, or whether there is another way to assure that ParentHWND will not equal zero without using a time delay?

I just bought a nice G15 Gaming Keyboard. It has a nice LCD screen with media keys (Play, Stop, Next, Previous etc,).Anyway, I managed to intercept the original functions to WMP of it (By Global Hotkeying them).Now, I have to send mouse clicks to my own Music Player (Playa!TraX, it isn't my creation) on a specific coord.This is the code i have, it finds the window, and says it clicks, but nothing happens, what am I doing wrong?

I know that AndAlso is equivalent to && and OrElse is equivalent to ||. But what is the cleanest way to achieve the equivalent of Visual Basic's And and Or in C#?For example, consider the following VB.NET code.The ValidateForControl method performs some validation and returns whether the state of the specified control is valid. The entire input form is valid if all controls are valid. However, each control must be individually validated even if one is invalid (which requires the operator not to short-circuit). Visual Basic's And operator is perfect for this situation, but unfortunately there's no equivalent operator in C# as far as I know (&& short-circuits).
What I am trying to do is to check if a value matches one of two numbers (and easily be able to add to the numbers to compare to). Rather than doing a longer-winded way such as: [Code] I have found that this only works when SectionID is 2 or PageID is 8. If SectionID is 3 or PageID is 12 then it doesn't work. Why is this and what can I do to try to get around the problem?
I'm normally at home in C#, and I'm looking at a performance issue in some VB.Net code -- I want to be able to compare something to the default value for a type (kind like C#'s default keyword).
