I am creating an Excel add-in written in VB.NET. I would like to bind KeyDown and KeyUp events to the spreadsheet to record when the user presses and releases the arrow keys while navigating the spreadsheetIdeally, these events would be built into Excel alongside the native SheetActivate and SheetSelectionChange events, for example. Alas, they are not.
View 1 RepliesI want to know how to do a keydown at form level. If I am not using Form Level the right way, this is what I mean. In my Form there is nothing.I want it so when the user presses a key that it will msgbox() something.As I said, there is nothing on the form what so ever No ComboBox, Button, nothing.
View 2 RepliesI have a program that I would like to create application-level MouseEnter and MouseLeave events for. Basically I have an app that I'd like to leave open that would be very opaque when not in use, and when the user moves the mouse anywhere within the bounds of the application, it becomes solid, and when they move their mouse away from the application, it becomes opaque again.
The obvious problem is that MouseEnter and MouseLeave are control-specific and so they fire every time you move over a button or menu or whatever, so Leave and Enter are constantly firing even though you haven't "left" or "entered" the application.
So, is there any way to create mouse events that only fire at the application level?
I am trying to use the keydown/keyup events with buttons in the same project and it not working properly. I have 4 red boxes and when I press an arrow key the box should change to green according to which arrow key it corrosponds to. I have this part working fine, however only when there is nothing else in the project. When I add in say 3 buttons, Button1, Button2, Button3 and try runing the program instead of the correct red box changing to green, button outline just moves between buttons 1,2 and 3. I have tried turning tabstop off for the three buttons but that didnt work. how to read the keydown/keyup while still having buttions that can be pressed with a mouse?

I have created a simple program which uses a two tier structure of SQL Tables.At the top level, one record holds the date of the activities and linked to it using its primary key as a foreign key, three subordinate tables hold time stamped records.The issue I have been unable to solve is that before adding any of the lower level records for a given date, a newly added top level record must be saved to the database.Doing this manually is simple - but can I rely on my users to remember to do this before they start plugging in the lower level data?I thought not, so I am looking to save the top level automatically.I've failed miserably but I refuse to believe that it's not possible.
View 14 RepliesI have multiple level of For Each and in each level, i have a Linq that is the 'In' criteria as in:
[Code]....
It will go inside each for (because the value is not nothing), however, it will only loop (next) in the very inner 'For Each t In tFor'. After it is finish inner loops, the outer Fors' or Next will not execute... even thought there are more than one values in that 'In'... like 'sFor' or 'fFor'. i've noticed while debuging, while break at the for (for example 'sFor', before stepping in), i get the error message:
"Enumeration yielded no results" when i expand the result for that variable and it will not step into it. but if i do not expand the result, it will step in. It seem that some how, once an element is accessed for that 'In' collection, it breaks (meaning does not loop for the rest of the elements) the next for that collection is this a bug or am i missing something in Linq? BTW: i believe it has something to do with the SqlDataReader in the Linq. I'm working with IAsyncResult.

View 4 RepliesI'm developing a software for my community library, so I'm searching for a VisualBasic.Net code to achieve the following objectives...
1. Get a list of all top windows displayed on a computer...?
2. how would I retrieve the images of these windows...?
basically the scope of the project is to be able to monitor client activity on the library's client computer systems such as being able to tell how many windows are currently displayed on a client's computer and if possible retrieve thumbnail images of the windows...since the library is hooked up to the internet, the software intends to block use of file sharing sites, and pornography. It is easy to block unwanted sites with certain software, that is if you know what site to block, sadly the list of malicious sites is growing daily... so visual monitoring is required...
My company uses ActiveDirectory, and naturally the IT department wants to maintain control over it and not give control to other users. I'm developing an ASP.NET app (for internal use only) using an SQL Server 2008 database.My question is, how can I BEST use the .NET namespaces and SQL Server to manage access to the app within the organization at the application (or possibly DB) level? I would like the user to be authorized based on their network username as provided by ActiveDirectory.On a side note, I would also like to access their AD contact information.
From my understanding I can use the ActiveDirectoryMembershipProvider class or Domain Services in the System.DirectoryServices namespace. There's also LDAP which apparently is another possibility. I'm having a hard time making sense of it all, and much less which is the best option and how to implement it. Can anyone provide me with some direction and possibly some simple sample code?
If I have a low level dll called low.dll. I then create another dll, say my.dll that references low.dll.
Now, if I create an application that references my.dll, I should not have to reference low.dll in the application correct?? This does not seem to be happening. The application will not compile as it cannot see low.dll, even though it does not access it directly.
How do you change an application level settings after compiling? I've searched Google and am at a loss. I've tried modifying the APPNAME.config file in the deployment directory but it doesn't change the application level settings.
View 3 RepliesI was reading a couple of articles a while back which I think described a behaviour where you can, in a .net application (specifically VB.net), allow an exception to occur, and then handle it in some kind of application-level exception handler, as opposed to within a Try/Catch block. My google-fu is weak at the moment, so I'm not having much luck guessing what this feature is called in order to find information about it.

I need to store a value globally (application level). This is part ID retreval program, procedure will return teh Max ID number thena i need to store the retreved value gloablly, so that if the user open many intance of teh same form i can use the gloabl value, to send Unique ID numbers to each form.
View 4 RepliesI bet someone already asked this but i cant seem to find it. Ok i need is a global settings that can be updated which will affect all users. I was using xml files in the program filestill now and I need to get around using this because the files can be delete or over written incorrectly. I started using the settings option and realized application level is read only and i cannot use user scope because then it wont be global settings. Is there an alternative to this.

Since this is a VB.NET forum I was hoping you guys could tell me why I should stick with VB.NET over a language like delphi.
been banging my head on this, i need to get the applications path, then go up 1 folder then into another. As i have a main app and sub apps.
So were Application.StartupPath()is for example:"C: Main app folderSub app folder"How do i then go up a folder to"C: Main app folder"I Know it needs some string removal using on it but i can seem to get it right, after which i could then use Application.StartupPath() 'string removal here" & " ools"to navigate to another sub apps folder etc.

View 1 RepliesI have a form with a button that brings up a different form. In some versions of this program (don't ask), the second form is shown non-modally, but in my version it is shown modally. The point of that last statement is that the second form can be either modal or non-modal, so an answer needs to handle either one, but the modal option is more valuable.If form 2 throws an exception that is not handled, the exception is caught somewhere on Form1, though the exact place that it is caught is largely dependent on where the exception was thrown from. The question is this: I need a means to trap all exceptions raised on Form2 or anything called from Form2 such that no exception EVER propagates out of Form2 to be caught in Form1. The reason for this is that Form2 HAS to perform some cleanup for reasons that I have zero control over. That cleanup doesn not absolutely require user input, but it would be good to have some.Is there any event that is fired if a form is exited due to a call stack unwinding as an unhandled exception propagates up the stack?
View 7 RepliesI've got a form with a listbox on it.In a second form I inherit the complete first form.

It may be inaccessible due to its protection level.What or where can I change this setting so that this listbox on form 1 is also available/accessible on form 2?
View 5 RepliesI have a form that consists of only a TableLayoutPanel (which fills the entire form) containing a vertical stack of buttons. The resulting app is used in conjunction with another app. What I would like is to have the vb app do something when the mouse enters the form. Unfortunately, all mouse enter/leave events are trapped by the panel or the buttons.
As a quick test I created a form with a tablelayoutpanel (docked to fill the form) containing one button. I added the following code:
