FindWindow API ?
Aug 11, 2009I'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.
Set Char Number Limit And Handle Special Chars In TextBox?
Jan 28, 2009I am a new VB programmer and am using TextBox in VB2008. Here are the problems I experienced in TextBox -
1, After I typed number in TextBox and found I need to type another number. So I used backspace key to remove it. But at this time program quit and displayed this problem: InvalidCastException was unhandled. How to solve this issue?
2, Can anybody tell me how to set number of characters are allowed to be typed in TextBox?
3, Can anybody tell me how to implement the feature that only numbers are allowed to be typed? In case letters are typed, how to tell user to re-type?
FindWindow API Not Working?
Mar 2, 2011Am 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"
[code]....
but is there a way to search for a single process without using a For statement?
FindWindow For CheckedListBox?
Aug 5, 2009I 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.
Equivalent Of Findwindow & Findwindowex
Apr 27, 2010Does 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.

May 15, 2009I 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.
Some of the code I have gotten online.

Use FindWindow, SetForeGroundWindow And SendKeys
Nov 17, 2006I 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.

FindWindow - Increase The Number Of Vendors To 10, The Programme Failed?
May 13, 2011I 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:

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?

C# - Handle Many "yes/no If Yes <display Textbox>" On Form?
May 29, 2012I'm creating a form in ASP.Net to replicate a paper form (I have no say in the design, I'm tasked with merely recreating it digitally). This form has many questions along the lines of "Answer yes or no. If yes, specify how much". I'm currently handling it by listing the question, and then having two radiobuttons in a group, one saying "yes" and one "no". To make this a little prettier, I've been using Ajax updatepanels that will only display a textbox to hold this yes value if the user selects Yes.Now I've been able to do this successfully, but each question is its own radiobutton group and has its own panel to update visibility, which means that the way I'm currently doing it there is a lot of redundant code like
[code]...
And so on for every question that has a yes/no option like that. I have no doubt there is a better way to do this. I was wondering if there is a way I could pass the panel associated with the radiobutton group so I could use a single method in the code that would fire for all radiobutton postbacks, something like (not real code)
[code]...
Or is there a better way to handle questions like this? I'm open to a different approach if it would cut down on the amount of redundant code that I'm typing now. I'm using VB, but I know C# so if someone is fluent in that with an answer I'd have no problem interpreting it.

View 6 RepliesVS 2008 Getting Handle For Registry Key?
May 11, 2009I have a section of code that will compile perfectly using VB Studio 2003, but it throws a InvalidCast Exception under VB 2005/2008. The code throws an Invalid Cast exception at KeyHandle = e(field.GetValue(KeyToMonitor) line below, and as far as I can tell it is because the variable Field is passing the string Microsoft.Win32.SafeHandles.SafeRegistryHandle rather than an integer. Is this because of safe keys in VB 2005 and 2008?
how to call the handle of the registry key opened in a way compatible with Safe Keys? I'm using the code to notify when a registry key is changed using RegNotifyChangeKeyValue.
