Window Keeps Minimizing Onload

May 10, 2012

I have a windows application created using 2005. One of the screens keeps minimizing each time it's loading and I don't know why. when I look at the properties for the form, the window state is set to normal.

I did have the below line of code being used when the user clicked a button on this form because i wanted to minimize the form at that time; however, I've sinced remmed it out because of what's happening now.

Progress Bar - Threading - Minimizing Window

Oct 17, 2010

Part of my application deals with creating a number of pivot tables. I pull data from a local database, and store it in a datatable. From here, the data is processed and eventually a pivot table is returned. On small data sets it works well, but on some larger one there is a few seconds of "nothing" until the table is shown.

After a few iterations of trying things to display some form of progress I have ended up with a form with nothing but a progress bar running on it. I spawn a new thread, and run it. It works exactly like I hoped. However, when I call the thread.abort() method to terminate the thread, occasionally, the main form will minimize. I tired having me.show() aftre the .abort() to bring the form into view again, but it appears not to have helped.

Now I understand that it is better practice to have worker background threads, and the main thread for UI, but is there a simple way of ensuring that the main form does not close?

Private Sub LoadProgressForm()
Dim progressForm As New ProgressBar
progressForm.ShowDialog()

System.Threading.Timer Fails To Fire After Minimizing Window?

Mar 16, 2009

I have used timers in .Net for a long time now an never had this problem.Start timer to fire every 10 seconds that reads an object and updates the UI using a delegate.This works great until the form is minimized several times, then the timer thread seems to vanish.Anyone come across this before?

Obviously I can roll my own using a thread directly and sleeping it, however this seems like reinventing the wheel when a threading timer class exists already.
Code: Private Sub m_Tmr_Tick(ByVal state As Object)

VS 2008 - Use "Go To Desktop" Function That Goes Directly To Desktop Without Minimizing Any Window

May 17, 2009

I'm working on one of my applications and I'm trying to find a way to use the "Go To Desktop" function that goes directly to the desktop without minimizing any window (This can be achieved by clicking on the Win + D buttons or on the desktop icon in the quick launch toolbar), but how can I activate it using vb? I thought about sending keys but I guess there is more offical ways to do it.

Javascript - ASP.NET: UpdatePanel & OnLoad Event?

Aug 8, 2011

I'm trying to execute some javascript code on my UpdatePanel's OnLoad event like so:

<asp:UpdatePanel ID="updDropDowns" runat="server" OnLoad="javascript:ResetButtons();">

But I keep getting "'javascript' is not a member of ASP.reasons_aspx".

I tried doing

Me.updDropDowns.Attributes.Add("OnLoad", "javascript:ResetButtons();")

But I can't reference the 'Attributes' property of an UpdatePanel in the VB code-behind.

JavaScript To Run After OnLoad But Before Any Function To Set Defaults

Sep 7, 2010

So I have an .aspx page loading up and populating drop downs based on a lookup table in the database. What we want is for the user to be able to configure which of these values comes defaulted by specifying that value in a drop down somewhere else in the app. Now, it's easy to default the "first" value, or something like that, but we want this to act differently. Is there a JavaScript function that can run immediately after onLoad (so the drop downs are populated already), that can go through the drop down and make one of those default so it looks like the page is loading with that set as default and people don't realize the workaround? (weird masking, etc.)

Here is an example of how we add the dropdown control to the page:
With CType(.AddControl(New Controls.ComboBox("CodeId", "../../../../CodeId", "Code")), Controls.ComboBox)
.ForceSelection = True
.ValueField = "LookupID"
.DisplayField = "LookupDesc"
.Validate.AllowBlank = False
.ForceSelection = True
.ReadOnly = EditControl.IsFieldReadOnly(10580)
.BindData(Model.Codes)
End With

FixedToolWindow And Minimizing?

Feb 22, 2012

I have searched now for hours trying to find a solution to this. I am trying to allow a user to minimize a form instead of closing it. I have tried about 5 different things so far in the form_closing event to minimize but have had no success. On another not, is there a way to allow the icon to be displayed? I know I could easily do this by using a different form layout but I prefer the compactness of the FixedToolWindow.

MDI Parent Occasionally Not Minimizing?

Apr 6, 2011

I have a MDI parent that opens another form like this:

Dim frm As New Form1
frm.ShowDialog(Me)

That form has a button that, when clicked, does this:

CreateObject("Shell.Application").ToggleDesktop()

The button operates as expected (showing the desktop) most of the time but occasionally does not minimize the MDI parent. All the other windows, including the form above get minimized every time.

Minimizing All Windows To Taskbar?

Feb 18, 2009

I have a program that has a main window, and a progression of other windows that all open from each other. I only want the main window to show in the taskbar, and I want to be able to minimize at any window, and have every window minimize to a single item in the taskbarThe problem is: when I set each form's 'SHOWINTASKBAR' to True, every form shows in the taskbar instead of just one. If I set the 'SHOWINTASKBAR' property to False, they don't minimize to the taskbar.

VS 2008 Minimizing If Then Statement?

Mar 8, 2010

I have 4 textboxes that a user can input date into, a save button, and another textbox that gets filled automatically depending on what is entered into the 4 text boxes.Lets call the 4 text boxes: Name1, Name2, Name3 and Name4 we'll call the last text box Complete.When you press the save button I want the values to be displayed in the Complete text box like this: Name1="text" Name2="text" Name3="text" Name4="text", BUT, only if they actually have a value.So if they all have some text in them except Name2 then the Complete box would read: Name1="text" Name3="text" Name4="text" - so Name2 wouldn't show up at all.Is there a simple way to put this in an If Then statement without scripting out every possible outcome?

I would like to know if you can stop a program from gaining focus or minimizing. And i know i can get the handles of open windows by the EnumWindows function?

[vb2008] Minimizing External Application?

Dec 27, 2010

like seen on the web, with both the two following codes:

ShowWindow(Hwnd, SW_MINIMIZE)
ShowWindow(Hwnd, SW_SHOWMINIMIZED)

I can minimize without problems an EXTERNAL application window from it Hwnd.The big problem is that once minimized the application cannot be manually managed: also if I close my program, both left click or right click on the external application taskbar button don't work: I can't maximize it and I can close it only by Ctrl+Alt+Del... why?

Calling Showdialog() On A Form - From The Main Form's OnLoad Event Makes The Modal Dialog Go Away After A Few Seconds?

Aug 7, 2009

I'm having an interesting issue that I can't reproduce on a different project, but can consistently on this one. I have no clue what might be causing it, but am hoping that someone may have seen it before.

I have a main form, from which I run a series of checks. On this form, I have a listview control. Because of some issues with the refreshing of this listview control, I had to create my own messagebox. It's just a form that displays some text ( it also happens to look nicer than MsgBox; in my opinion, anyways ). It's been working great for months, until recently.

My problem is that on my main form's load event, I run this check, which returns an error within a try/catch block. I then call my custom messagebox with a message. It in turns calls it's ShowDialog() function.

In any other situation ( after the main form has been loaded ), I have no problems. The messagebox goes on the screen and behaves appropriately ( ie: waits for my input and acts as a modal dialog ( stops execution of my main form's thread ) ). However, on this onload event, my messagebox comes up and goes away almost immediately afterwards.

I've traced it all the way to the showdialog() call. For no explicable reason, it appears to skip right over this call, without me doing anything on the form.

Here's what the inner trace looks like ( when I put a breakpoint on the onclosing event for this messagebox form ):

I am writing a little app to take over from Active Desktop as we are using Win7.

I am having problems getting my form to stay open, if the user hits the "Show Desktop" button the form minimises. I need this to stay open at all times in the back ground.

I have disbled the minimise button to stop the users using it.

how I can stop this from happening or if I use a timer to check the windows state it apears normal as it looks like the "Show Desktop" button does not actually minimise the window!

Find The Handle Of The Child Window For The Yes Button In The User Account Control Window?

Mar 20, 2010

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?

Capturing Audio Stops When Main Window Is Minimized Or Obstructed By Another Window?

I have a VB.NET application that uses Managed DirectSound to capture audio.Everything works just fine until (a) the application is minimized or (b) the application is completey obstructed (covered) by another window.

The thing is that the CaptureBufferDescription structure does not include a GlobalFocus property so I don't know what to do to let my application continue capturing when the main window is hidden.

Here's the basic initialization code I'm using:

border of that said window so the only place the mouse can't click the titlebar and the minimize,restore, and maximize button. The height of the titlebar depends on what OS the user is using so I'm having trouble because I can't give a definite value for this. How do I detect the height. and also for border i'm not sure if the borders have different widths with different operating systems. I'm using windows XP on classic mode, when I change to the themed mode, the height of the title bar changes so it won't work.
