there is any event or way to detect activity in an form or project?in the form and all the child controls.
mainly mouse clicks (not mousemove) and key press.
for example, if the form have not activity in the lasts 10 minutes, do something.
I was wondering how you would go about making it so that, whenever you have a form open, or showing, that it won't allow any other clicks outside of the form content. Kind of like when a critical windows error shows up, and you can't do anything on your computer, until you press the "Ok" button to get rid of that popup message first.
How would you do that with a form?
Let's call it Form 1 and form 2 for example. I have form 1 as a default for when the application starts, but when I want form 2 to show, I want the user to have to deal with that form first before they can do anything else on their computer.
I need to detect shift + arrow key in blank form. But it's not working. I also tried overriding IsInputKey method but it only detects single key press (like arrow key) but when multiple key are pressed it simply doesn't work.
View 5 RepliesI'm in the process of creating a tool that allows users to download stuff from a LAN server. The progress of the download is now being shown as a progress bar that performs a step each time a file is downloaded.
But if the file is a large file (Let's say a 2 GB file) it'll take a while before the progressbar performs a step and the user might think the tool froze up and close it. Now i'm wondering if there's a way to show the activity on the NICs installed. Something like when you open up task manager and go to the "Networking" tab. Showing it as a graph would be awesome or just a percentage is good aswell I have NO idea where I should start looking..
I'm trying to write a simple program to monitor a folder for new files in VB.NET 2010, and am having some trouble. Here's a simplified version of what my program looks like:

I know you have to use WM_EXITSIZEMOVE or whatever it is, but I'm just not really sure how to use messages properly...I've read a few things online but just can't get it to work properly.
I'm looking into making child forms dockable inside my parent form and want to know when to hide my dock labels again (after the child form has stopped being moved).
I want to create a custom form (in visual basic .NET) that will stop other process responsiveness until the form is acknowledged. It would be a nice bonus if I can add a beep when trying to access the main program UI while this form is displayed as well (like how a messagebox does).

Inside a form, I would like to display a pdf file which is already available in my resources (template file "untitled"). In this pdf file, I have some fields which get their values from some texboxes in another form. My aim is, when the user triggers the button to call this form, it should insert the values inside the pdf file and display the output pdf inside the form.I have written the code to an extend but could not finish it myself after my many trials... Now here are the two things I cannot manage:I can use a directory to read the template pdf "untitled1.pdf". But my aim is to use the file inside my resources. can save the output file in a directory but this is not I want to do. I want to display the output pdf.
View 1 RepliesIs it possible to resize my controls on my form when I run it? The problem I have is that I have created a windows application which has a maximize state on all forms but on some machines my controls go missing (mostly on widescreen laptops). Ideally some way of resizing my controls would probably be best? So is that possible?
View 10 RepliesI've run in to a very annoying situation. At the moment I have a program with 4 forms. 3 of these forms work fine, but the fourth seems to be a dud. After clicking any one of the buttons or controls on this form it works. But if I try to click anything again, it doesn't work. I can't use my back buttons, I can't even use the minimize, maximize and exit buttons in the top right corner which are automatically built in to the program. I fear I have accidentally changed a setting, or accidentally deleted some very crucial code for this
View 8 RepliesWhat I am trying to do is have a Form which can dynamically change the controls which are on it and their properties; this allows my main GUI to be more fluid and not have tons of groups and controls on it which I must hide and show when needed. To make this as extensible and reusable as possible, however, I want all the control additions/subtractions/edits to occur through a separate DLL which I write. The problem is, I can't seem to instantiate any controls in the Class Library because I cannot import 'System.Windows' or any of its children ('Forms').
View 9 RepliesI did a quick net search and found this which works great for looping through all the buttons to disable them. These buttons are located right on the form.
For Each ctlControl In Form_BLAH.Controls
Select Case TypeName(ctlControl)
Case "Button"
ctlControl.Enabled = False
End Select
Next ctlControl
However...when I tried it on a form where the buttons are contained within a Table Layout Panel it does not work.
Where is the best place to resize a control on a form when a form is resized?....I'm currently using the Form1_SizeChanged event and seems to work ok. Also is there any need to check in the forms resize event if the form is in a minimized state before resizing controls?.,.. in VB6 if you try to resize a control when the form is minimized you get an error, but I don't see that happening in BV10 Form1_SizeChanged event, does VB10 automatically ignore resizing controls when a form is minimized or something?

View 1 RepliesI'd like to design a Winform with expanding controls if that 's overly complicated. The idea is that I would have rows of information, each with an "Expand" button. On pressing the button, the rows underneath the selected row would move down and the controls that are associated with the selected row (some textboxes/ dropdowns etc) would appear. Vice versa when you click the "Hide" button.
View 2 RepliesI'm trying to make an autoupdater, so I've made it search for updates in the beginning and that works fine. But now when the update form is supposed to open, it goes a while and then it says "File Download Complete". So that means the form must have been executed, but it does just not appear. But when I click ok on the dialog, the updater form appears, but with all controls white. Here's my updater.vb: [URL]
I'm using Kleinma's WebFileDownloader class.
I suspect that the problem might be that the updater's form doesn't get it's events handled or doesn't get redrawn.
