Application That Reads MDI Applications Child Window And Grabs Information From A Control
Apr 23, 2010
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. [code]

My application reads information from an Excel spreadsheet into a DataSet (ds1) which is then filtered into another DataSet (ds2) based on user-specified criteria. The information is basically telephone call logs that reflects when a phone call was made,what extension it was made one, how long the call was, what number was called, etc.When the user's "search" criteria is matched in ds1 above, the application adds the number called to a ListBox on the form. When the ListBox Item is selected, additional information (call duration and such) is displayed to the right of the ListBox. My problem is that a single phone number could have been called multiple times on an extension within the date range the user specifies and for each occurrence of that number in the ListBox, the "expanded" info only reflects the information for the 1st call to that number listed in the DataSet.
The only unique identifier I have is the DateTime field for the row (as this goes up to the second). I thought about putting it into the ListBox item, but I'd prefer that this date not be visible until the user selects the ListBox item to view the details for that call. [code]

I am trying to find the handle of the child window for the Yes button in the User Account Control window so i can click it. This window has a structure with a few child windows with the same name.
Dim hwnd As IntPtr = FindWindow(Nothing, "User Account Control")
Dim hwnd2 As IntPtr = FindWindowEx(hwnd, 0, "DirectUIHWND", vbNullString)
Dim hwnd3 As IntPtr = FindWindowEx(hwnd2, 0, "CtrlNotifySink", vbNullString)
Dim hwnd4 As IntPtr = FindWindowEx(hwnd3, 0, "Button", "&Yes")
There are multiple CtrNotifySink with its own Button child window or other child windows. How do i search thru the different CtrNotifySink window to find the one that contain the Yes button so i can send a click to it? I do need to find it before i can send a click, right? because i try just sending it to the main window with sendmessage and nothing happen.I even try sending it directly to the handle found by spy++ of the yes button with bm click but nothing happen?

I need a tool window to act like a mdi child over a chart control. I can't use mdi because I'm using the krypton control ribbon component and they pretty much use all the mdi code in the background. Anything I do mucks it up. So I need a window to float over another control and be bounded by the real estate of that control.

I'm in the process of converting a VB6.0 application to VB.Net (2008 Express). I have a MDI parent form, I'll call mdiBackground, and 4 MDI child forms, frmStatus, frmShow, frmQwerty, and frmSentence.The layout is as follows:mdibackground - has the menus at top and is a container for the child forms.frmSentence - appears at the top frmShow & frmQwerty - appear at the left and when one is closed the other one is in the same position.frmStatus - appears at the right, it has buttons which control when frmShow and frmQwerty are to appear I have a couple of regular forms that act as dialog forms. The Me.Close() works fine on these.

[Code] my problem is if i search the class node with the name attribute of value "IT MAJEL 03", the xml reader reads through the first class which is "IT MAJEL 04" and read all of its child nodes(which i think is very awkward. why continue reading to its child nodes if the class name you're looking does not even match). is there another way to actually jump the reader of the xml node to the next xml node of the same level?
I mean if I search the class named "IT MAJEL 03", the reader should jump to the next same level element it does not match the query. It should skip reading the "IT Majel 04" child nodes. what I want to achieve here is I want to save nanoseconds of computing.

I have a 3rd party program that puts up a pop up box and asks the user for input. In Spy++ the original program (I'll refer to this as Window A from now on) is a top level window, and the popup (Window B) is also a parent window. However, when I use FindWindow(Nothing, "Captcha Challenge") it returns 0. I've also used a code snippet from the forums

I am looking to close the application when I click a cancel button in a login page, but I don't want to do it in such a way that Window 2 closes itself, but by sending some notification to Main Window, and Main Window closes the application. Here's the code that I have so far:
(in loginPage)
Public Event CloseApp As EventHandler

If I show a new non-modal child window using .Show(frmParent), and then the parent window is minimized, the child will get minimized automatically as well.

I have a hardware which sends out packets containing 17 bytes to the comport in bursts of 3. the little test VB that I have written receives and displays the bytes in a line of 17 bytes long and works fine until it gets to around 170th packet, then it starts to mix up (looks like shifting the data left) the bytes shift mostly by one digit sometimes by two. then it will continue to give almost a packet correct and a packet shifted for about 50 packets. Then it will correct itself for a long while, but then the speed at which it receives drops. All the packets are sent 3 times, and before things go wrong (within the first 170 packets) the packet counter shows that it receives 3 packet each time but after the problem it goes to 2 packet per burst and then to one.
If i close my VB monitoring program say at packet 165 and immediately open it again, it wont go wrong for another 170 packets, this points the finger at VB. I have check my hardware, there is no problem with that.The program reads port - waits for 17 bytes - once 17 has been received it will go and buffer the packet in an array. In fact they are 2 arrays but printing fro either results in the same problem.I have tried whatever i could think of but to no avail, i am wondering if some kind of house keeping needs to be done to clear something... I am sorry the program is a bit messy but I have been making many changes to find out what the problem is - my code below:[code]

I want to develop a small application that reads in scanned barcodes into a database table - Would a vb.net form based application that connects to the database be best approach? What I'm think is each time the user scans in the barcode - a message appears on the form saying the barcode that has been scanned.
1.Would I need to program anything within the program to check whether the barcode scanner is connected (or is this not necessary since it works like a keyboard device?)
2. How could I automate the scanning in without requiring any user intervention like a button which saves it to the database - so basically as soon as a barcode is scanned in - it is saved to the database and the next barcode can be scanned in etc.

I'm wondering if its possible to change the query that grabs the data from the dataset at runtime, in order to produce a report based on different criteria.My project doesnt use dataset, and I've had to make one purely for the reports I'm currently using the mySQL .net connector calling everything via code, as well as the query I want to make at the time.Also, I don't want the report to be embedded in the application but be a seperate file as the report may change frequently (the layout of it)I've tried setting the build action as none, but I just get an error in the intermediate window.

(vbnet 2008, windows forms)I have a main form (not MDI) with a menu that will open another form as a window on top (I have already set the TopMost property to true). My problem is that it will set this window on top of everything that I open (any program). How can I set this window to be on top of just the main form? I guess I have to declare the main window as its parent, I tried the code below but it didn't work...

Private Sub FilterToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FilterToolStripMenuItem.Click
