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).

I have a NET (version 3.5) Class Library written in VBNET 2008 (on Windows 7 x64) that will at times display a WinForm. The class lib will be used in Excel, and I want to set the NET WinForm to be a child of the Excel Application window. If I weren't using NET, I would just call the SetParent API function, but I can't seem to get this to work since WinForms (I assume) don't have a HWnd suitable for SetParent. I'm sure this is possible, but I just can't find the right properties and methods. The WinForm will be shown modelessly so the user can switch back and forth between Excel and the displayed WinForm.

I'm looking for a way to monitor drive activity using Visual Basic 2008. I want to create a small utility to simulate an LED in the system tray for drive read/write activity. I've found several such utilities that do this, but they all lack one thing or another, or they are over bloated with stuff I don't want or need, etc. I want to write my own so it will be like I want it. To get started, I need to know how to monitor drive activity.

I'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 have a test that can run for many days depending on some oven controls, etc. I would like to have a "HALT" button on my form that will stop the test if the user decides to.For example, lets say my "btnRunSomething" click event fired and I'm looping in there for a long time. When the "btnHalt" click event is raised, how can I stop the "btnRunSomething" sub's execution? After stopping execution, I will close the connection string to the oven as well and dispose of everything properly.

I am writing a program with a loading bar. I also have a label that says what the program is currently loading (Eg. 'Generating Numbers...', 'Determining Winners...').
It all works fine, but the label sometimes doesn't change or doesn't even appear because the program is too busy processing all the other stuff. I hope that makes sense...
Is there any way to centralize processing on the label and progress bar at times?

View 1 RepliesI work in IT in a firm that are rolling out a time management application on all PCs. In order to clock in/out a user must log into the application and click clock in/out. I want to build a very simple application that when a user goes to shut down or log out of their PC, a windows form will pop up asking them if they they want to clock out of the time management software (a reminder if they have forgotten to clock out and are heading home). On the form there will be two buttons, 'yes' and 'no'. If they click yes, the system shutdown or log off will be halted and the time management software application will open automatically. If they click no, the shutdown/logoff will proceed as normal. I just need to know what i need to do to get the system shutdown/logoff to stop until either button is pressed and to stop totally if the 'yes' button is pressed. I am able to get the Time Management software to run on a button click but just not able to halt the shutdown or logoff?

View 11 RepliesI have a mini form application. What I need is to have a message box asking the user to confirm exist. Yes/No. This should happen if the user click the exit button on the form or the (X) on the title bar.
I have this piece of code attached to the exit button on the form. I'm trying to use an if statement but don't have a clue as to how I can apply it to what I already have.
Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click

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.

View 4 RepliesI have a section of code in which I want to display a messagebox after a form is displayed... as the form loads. me.show messagebox.show If I don't use me.show first, the messagebox appears before the form is displayed.

View 14 RepliesI am a beginner, working on MS Visual studio 2005. I have made a form which accepts details from a user (name , age, etc.).....what I am trying to achieve is the following:
When the user enters all the details and presses OK button, a new form or a messagebox must open, displaying all the details just entered by the user.
I have a form which contains a progressbar and a Listbox which update as the code runs through and performs some sometimes time-consuming calculations.
At one point in the code, it breaks to ask the user to enter a number using :
Usedefault = MsgBox("Do you want to use the default value of " & Default_No & "?", vbYesNo)
If Usedefault = vbNo Then

this works fine but I find that once the data entry is complete, and the code continues to run, the form loses focus and the progressbar and the Listbox updates cannot be seen until the code finished its calculations.

View 4 RepliesI have a parent form, which can lanch a dialog box. A wrong selection in the box launches a message box with an error message. When the message box pops up, the dialog box disappears, so the messagebox is sitting on top of the parent form.Once the user clicks "OK" in the messagebox, the box disappears, and only the parent form remains.How do I make it so that the dialog box remains when the messagebox is displayed? And also, I want the dialog box to remain when the user closes the message box. The user should have the option to make the right selection in the dialogbox once the messagebox disappears.I tried to hunt for a property for the dialog box to achieve this, but couldn't find any.
Here is the code in the parent form to lauch the dialog box, and to also launch the messagebox, when the user has made a selection in the dialogbox:[code]Am I having this problem because all the code to launch the dialog and message boxes reside in the parent form? If I put the code to launch the messagebox in the dialog box, would that make the dialog box persistent when the messagebox is launched? I am putting all the code in the parent form because it can process the DialogResult.
When a messagebox pops up, how can I bring a form infront of the messagebox (or switch betwen different forms) and then bring the messagebox back again again if I want to click OK button to proceed with the remaining code?

After using a form as a replacement for MessageBox I do have a need to make it automatically adjust its size to fit its contents, is there any rule out there that we need to abide to when it comes to sizing the form acting as MessageBox?
I am thinking I could use a panel that will auto-resize and just resize the form according to the size of the panel but I am not sure that will work as I haven't tried it yet.
I've created a form with several controls to specify the inputs to my program. They include TextBox, OpenFileDialog, Button and even a user control for numeric input. When the user clicks the 'GO' button, the program begins it work. Opening several files and processing a bunch of numerical data. This could take many minutes/hours with large datasets.
What I've been trying to do is have another window/form open up and send status information to it for the user to view. The info to be displayed is varied and constantly updated as the program crunches the numbers. Many many programs do just this type of activity.
I attempted to create a second form with a huge TextBox thinking I'd just write stuff to it. I called the .show method within the .click of the 'GO' button and of course the form is displayed but control of the program's execution doesn't return until the form is closed. How to I maintain execution and have a second window/form to display status?
