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'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"
[code]....
but is there a way to search for a single process without using a For statement?
I am having difficulties populating a checkedlistbox (CLB) based on the selection(s) made in another. It should also be noted that I have a "Select All" checkbox at the top that checks/unchecks all of the items in the first CLB. Here's the code:
[Code]...
The first CLB is populated with an arraylist of values on the button click event. Based on whatever is checked in the first CLB, corresponding values from an arraylist of structures should fill the second CLB.The following code partially works until the "Select All" checkbox is clicked at which point if other values have been selected before "Select All" is checked, the second CLB is filled with the correct number of corresponding values BUT only those of the most recently selected item of the first CLB instead of all of corresponding values of all of the items that were not already selected.
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.
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")

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?

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?
Trying to get a database into my Checkedlistbox. This is the code I have so far: Private Sub CheckDevices_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim connectionString As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=N:DeviceList.accdb" Dim str_DeviceList_Select As String = "SELECT * FROM DeviceList" Dim myConnection As OleDbConnection Dim myCommand As OleDbCommand Dim myAdapter As OleDbDataAdapter Dim myDataSet As DataSet
[Code]...
So I have the dataset with database in it, but I am struggling to get it from the dataset into the Checkedlistbox. Could someone do some quick code for this?Secondaly, I also want to set the checkbox's by using a string of integers which will look like "0110100110". If the value is a 1, I will want the corresponding checkbox to be checked, eg, "0110100110" So I would take that one, and check the 8th checkbox down in the checkedlistbox... So if anyone if feeling really generous, could use a little help with this as well.
I have a CheckedListBox that will be used to choose what columns they want to select from a database. Is it at all possible to display it in the format of [Table Name].[Column Name]?So far I have this:
con.Open() theQuery.Connection = con theQuery.CommandText = strColumns theAdapter.SelectCommand = theQuery
[code]....
I tried adding another clbFields.DisplayMember, but this obviously just overwrites the table name with the column name. I also tried doing:
but that didn't work either.I know it's not exactly life threatening if the user can only see the column name, but it'd be nice to be able to see the table name in case of any duplications?
I have a few checkedlistboxes in my GUI and the items in them are changed as needed. For example if I check an item in checkedlistbox1, it would trigger the items fromcheckedlistbox2 to be removed and new items will be added to it that are relevant.Similarly, depending on when the items are checked inside the checkedlistbox2, it will trigger new items to be added to checkedlistbox3. So I have added the functionsSelectedIndexChange to handle when items are checked inside the boxes.
I am running into a problem however. For example, I have some items in the checkedlistbox2 and one of them is already checked. When I click on something else in checkedlistbox1 it clears out all the items and repopulates the checkedlistbox2. In that case, however, since something was previously checked in checkedlistbox2, the selectedindexchange event is also triggered for that one as well because something was changed in that. Can I disable this somehow because technically I didn't "check" or "uncheck" anything, all I did was remove a checked item? I tried doing something like adding an if statement inside the
Ive got a CheckedListBox where I have a list of devices and a checkbox to tell me whether they are on or off. I want to be able to change the checkbox in the program of a specific device and then when I click submit, it to generate a string of numbers to tell me what boxes are checked (1 for on, 0 for off)Example: Boxes 1,3 and 7 are checked in the checkedlistbox, and there are 8 total, so the string outputed would be "10100010".
I have an Edit Bank form with a checkedlistbox. When the user clicks a bank it loads the edit from and checks the states that that bank lends in according to my database.i am trying to write and update statement so if the the new states are checked or unchecked, I want the database to update when i click save.I use an arraylist to store the items then read through and see which ones are checked.[code]
Is there a Tag for an Item in the CheckedListBox? Or something similar? I would like to be able to store and ID associated with the item that I'm displaying.
