How To Check If Form Is Shown / Hidden
Jan 1, 2010I can show/hide a form, but is there anyway for me to check if a form is hidden/shown? After the form calls InitializeComponent(), and activates the OnLoad Event, it automatically calls the Show() of the form. I do not wish my form's default startup mode to be Shown. I tried overriding onshown method and call Hide in OnShown. It works but this method looks pretty ugly to me though so is there anyway that I can stop the form from even calling Shown when it was first initialized?
View 31 RepliesCheck If Row Is Hidden?
Apr 6, 2011I have a little trouble with my code. You'll see. I'm using the developer express ridControl tool. I have a Gridview in it with a table bound to it. The control lets you filter your info. I have a Select all button that works, the only problem is that if you filter the data and press the select button it selects all the rows, not only the ones that are actually shown on the grid, and I need only the shown ones.
View 1 RepliesGet All The Id (hidden Column) Of All Check Items?
Jun 18, 2012I have this issue right now. I have a listview with checkbox. Now what I want to achieve is get all the id (hidden column) of all check items and pass it to arraylist so that I can pass it to SQL like this:
dim intProductID as new arraylist
For i = 0 To lv_list_products.Items.Count - 1
If lv_list_products.Items(i).Checked = True Then
[Code].....
"DELETE * from t_products WHERE f_product_id in(" & intProductID & ")" The reason I do this is to have only one time open of database connection, One of the member suggested it is not good to open and close database specially if it is within the loop. One more issue is the command within the array I need to separate all id with commas so I will not have error on SQL.
TopMost Form - Messages Form Would Be Hidden By The Main Form
Nov 20, 2009I have a tool window that I want to stay above the main application form, but not stay on top of all windows forms. Similar to the floating properties window for visual studio - it always stays on top of the main VS window, but if I select another program, like internet explorer, the floating properties window will be behind internet explorer.
What I have is an application that has several forms that may be displayed at the same time. I have a Messages form that displays messages generated by the code in the form, that gives the status of the application. Obviously, the user would not normally be working on this form, but they may want it to be visible to see the status messages from the program (File saved confirmations, etc). So, my two options right now are I can set the form to be on top of all other windows forms or, when the user clicks on the main application form, the messages form would be hidden by the main form.

View 1 RepliesForm Is Hidden Behind Other Applications
Mar 27, 2009I have made a validation application, the application runs in the tray and responds to events of another app such as save document, on this event my application runs, validates the document and creates a pop up message of errors in the document. However the pop-up is hidden behind the other application, the other application is locked because it is waiting for my app to finish. I have tried combinations of show(),activate(),bringtofront () with no success i have also tried SetForegroundWindow() and SwitchToThis Window() for win api but with these the app still just flashes orange in the taskbar behind the other application which is locked.I think it is almost definatly a problem with stealing focus from the other application but im not trying to make an annoying pop-up, it is needed and only appears when there are problems with the document the other application is locked and will not respond untill okay is clicked on the pop-up and it is easy to miss the flashing icon in the taskbar

Datagridview Seems To Cause Startup Form To Appear Even After Been Hidden?
Feb 15, 2010I have created a DB with access and imported it into my application. What I am trying to do is startup with regi.vb and test to see if there are any entries into the DB and if so, hide the startup form(regi.vb) and show the login.vb form. have done a test and it loads regi.vb then I enter some details into the textboxes and then after clicking a button, it inserts the info from the textboxes into the DB. It then loads login.vb, which is fine, but then if i exit the app and reload it, it tests to see if there is anything in the DB and when it finds that there is, it reloads the bloody regi.vb(startup form)!!So why, when it discovers that the DB is not empty, it re-opens the startup form??
I have used login.show()
me.hide()
Here is the code for the startup form (regi.vb)

VS 2010 Show Dialog From A Hidden Form?
Oct 6, 2011I'm trying to create a program that will look at a website and check it for updates, similar to an RSS feed. It then will show a dialog (Form2) that will inform the user that there is an update.Form1 is used as the configuration form and is able to be shown via a notify icon in the system tray, which is on Form1.Originally I would have Form1 hidden via Me.Hide() and then run a timer which would check for the updates and call Form2.ShowDialog() when there's an update, I found out however, that if Form1 is hidden, the dialog will not show.
Next I tried not Hiding the form, but instead setting its ShowinTaskbar property to False. At this point the program functions correctly, however when I minimize Form1 it sits in a shrunken window near the task bar... Is there any way to completely hide Form1 (when minimized), and allow Form2 to be shown as a dialog?

Popup Closed - Main Form Hidden Behind Other Windows
Oct 26, 2011Using vb.net. I've got a main form that displays when application is opened. A popup form can then be opened. If there are other windows opened on the desktop, for example windows explorer, then when the popup form is closed, the main form gets hidden behind windows explorer. You have to move windows explorer out of the way to get to the main form. Is there a way to keep this from happening?
View 2 RepliesVS 2010 Splash Screen Hidden By Maximized Form?
Feb 9, 2012I have a Windows Form Application to which I added a splash screen created using the splash screen template. I also added an MDI Parent Form. In my project properties, I chose the splash screen and the MDI Parent as the loading form.
I want the MDI Parent to load Maximized, so I changed the WindowState Property in the list to do just that. Now here is the problem:
If I leave the WindowState set to Normal, the splash screen loads, does its thing, closes, then loads my MDI Parent just like it is supposed to, BUT, if I set the WindowState of the MDI Parent to Maximized, the splash screen displays for about a second, the MDI Parent loads on top of the splash screen, and the splash screen finishes in the background and then closes.
I tried giving Focus back to the splash screen in the Lost Focus event but that didn't work. I know splash screen is still open and working when it gets covered up because I can hit ALT+TAB and see it just before it closes on its own like its supposed to. I also never adjusted any of it's time settings or any other settings.
How do I keep the splash screen on top while my MDI form is Maximized? or how do I delay the MDI until the splash screen has done its job? I dont understand why I am getting this result.
Start A Form Hidden - Make The Tray Icon Visible
Feb 26, 2009My FormLoad event contains a simple line which is Me.Hide. Then I make the tray icon visible so the application can be shown if the user needs it. However, the Me.Hide statement doesn't work during the form load procedure. It seems to work fine after the form has been loaded. So, my question is, how can I simply stop the form from becoming visible in the first place or hide it after it has loaded?
View 4 RepliesVB: Getting Checkboxes On Windows Form To Check If Their Values In A Database Field Is Check (True)
