I have an application written in VB.net 2003, and I would like to make it 'dpi-aware', but I haven't the faintest idea how to even begin. I am an experienced coder, but this is throwing me completely.
View 1 RepliesWPF question here, I'm using VB.NET as the code-behind so I figure I might get away with posting it here :P Just in case anyone has any ideas.I've got a StoryBoard that runs on MouseEnter and MouseLeave, basically all it does is scales the control up a bit to make it larger and moves it accross the screen slightly (on MouseEnter) and then on MouseLeave it just sets it back to how it was.
The problem is that the animation lasts for about 1.5 seconds, but if the user just passes their mouse over the control and then half way through the animation they move the mouse off the control then the second StoryBoard kicks in but starts with the control in its final position from the MouseEnter animation. Obviously this results in a "skipping" or "jumping" effect in the animation and is less than ideal.So I'm just wondering how you are supposed to make it so that if an animation is half way through and then another event is triggered so another animation starts then it kind of 'gracefully' hands over to the animation that is starting.
How does one add the DPI-Aware entry to a manifest in a Visual Basic application?

View 9 RepliesI have a Sql Server 2008 R2 Failover cluster running an active and passive node talking to a shared disk.
I have developed a vb.net windows service which needs to run on each node under clustering conditions.
I need to understand what I need to do to the service to make it cluster aware.
There are a few heavy classes in the service which under failover conditions need to understand where they are in terms of what data is in them so that when the passive node kicks in and the service starts it picks up on node 2 where it left off on node 1.There is near little documentation on this subject I can find on the net and with companies becoming failover happy this needs to change.
I'm experimenting with a plugin architecture for my company's internal business system. I have managed to read all .DLLs in a Plugin folder which implement a specific interface. What I am trying to figure out is the best method of communication between the "host" MDI parent application and forms that will be in the .DLLs which I intend to make MDI children.
Currently, I am returning just ToolStripMenuItem objects from the .DLLs to add to the MDI Parent. I've also tested that events wired in the .DLLs to the ToolStripMenuItems do propagate to the code in the .DLLs. I've also managed to return a Form object via the interface and open that form, as the Plugin folder is being "scanned".
However, I am not clear how I would make these forms MDI children. Also, any other forms living in the .DLLs will also have to be MDI children. I created a VS 2008 Addin project just to see what's going on, and it seems that the Addin accepts an Application object on which it adds to the ToolStripMenuItems and does other operations. The code to build the menu inside the .DLL. This is opposite of what I have done so far, where the MDI requests a ToolStripMenuItem from each .DLL and adds the returned object to its own menu.
Would designing my plugin architecture to accept an application object in the same manner the only way I could get forms to open as an MDI child? Am I asking for other, currently unknown to me, headaches by NOT passing in the application object to the .DLL?
I am making a exe application and i am using mysql as my database. So the thing is, when i change to a new computer, i need to change the file path for the database connection string to that computer.
like below:
Dim connectionString As String = "Data Source=----------SQLEXPRESS;Initial Catalog=Flexlink;" & "Integrated Security=SSPI;"
i need to change the data source = --------------- SQLEXPRESS to the computer name that i am using for my project.
May i ask is there any method such that the user dont have to go in to the source code to change the computer's name like those normal installer?
Just install and the application will run according like any exe file that we buy.

I'm currently using MS Visual Studio 2008 Express Edition. My .NET Framework version is 3.5. I made an application in VS 2008 and it worked perfectly. However, when I ran it at my friend's place (who's got .NET Framework 1.1), it didn't run. Now, I know that the framework incompatibility is the issue.So, what I ask is, how do I code the application so as to make it run on Framework 1.1 as well while still using VS 2008?

View 7 RepliesPreviously I used to piddle around with VB6 to develop a couple of personal projects. Following my upgrade to Windows 7, I've decided to piddle about with vb.net Express Edition 2010.If I wanted my VB6 application to blend in with the visual style of Windows, I would use the code and techniques described here. In short, I would use a Manifest file and a couple of calls within the application and most of the elements would look similar to the XP theme applied. If it was run on 2000, 95 or 98 then it would look like a standard Windows app. All was good.
Now I've moved onto vb.net, I've written a simple "Hello, world" application but I have absolutely no idea on how to make it look like the Windows 7 theme (eg. the font matches the system font and the widgets are styled correctly).Just changing the font is a hack and will look out of place on machines that are set-up differently or run a different version of Windows where the default font is different.How do I ensure my application matches the applied Windows theme irrespective of the version of Windows?
I created a simple application that when a user logons onto their Windows account, the application pops up to display the computer usage agreement.آ The user at this time has the option of accepting it or declining it. If declined they are logged out of windows, and if they accept they can continue using windows. When I installed the application logged on as the administrator, it only installed in the administrator profile, thus not allowing the application to be run from startup under any other account except admin.آ My first question is, how can I install this application that is it accessible to all user accounts? The second question is how can I program the application to freeze windows until the user clicks the accept button, without puting a timer event that if the accept button is not clicked in a certain amount of time to log off the user.
