I'm creating a WPF application in VB.Net. I am trying to decide where my startup code should go. I seem to have two choices: Leave the "Enable Application Framework" box checked and choose a "Startup URI" from among the application's windows. Uncheck "Enable Application Framework" and choose to startup in my own Sub Main.
[Code]....
The Enable Application Framework Check Box seems pretty well defined in a number oprevious postings, but leaves one question in my mind. The default is unchecked and the sub-topic Check boxes are:
Enable XP Visual Styles - - Checked
Make Single Instance Appllication - - Not Checked
Save My.Settings On Shutdown - -Checked
There are also 3 Combo Boxes:
Authentication Mode - - "Windows"
Shutdown Mode - - "When startup form closes"
Splash Screen - - (None)
When I un check the Enable Application Framework Check Box all items under it are grayed out. However, if I have changed one of the Comb Boxes my selection is also grayed out...My question is, have I lost the use of those function: Specifically I am mos interested in starting my application from a Sub Main and closing the application when all forms close.My underlying question is . . . are the greyed out selections still valid?
What it is the option Enable application framework that I found in Visual Studio under VB.NET WPF projects Application settings?I found it enabled by default and the "Shutdown mode" configured as "On last windows close". But for me is not really clear what does it mean that setting and also the other settings listed in that combo box.
View 1 RepliesI am writing an application that puts a computer in hibernation mode (Application.SetSuspendState). I have noticed that there exists a specific option that needs to be enabled for the machine to hibernate correctly and that is found in Control Panel--> Power Options --> Hibernate Tab (if this option is not checked then the machine goes into stand by mode rather than hibernate) Is there a way to programmatically check the status of the "Enable Hibernation" check box and check/uncheck it?
View 2 RepliesI am in the process of developing a messaging framework for a windows application that sends messages to a java application. To be precise when the win app wants to send a message it simply drops the message in a common database table which will be picked up by the java app. The windows application is deployed across 10 application servers (10 instances) over citrix for load balancing.Each instance of the application is capable of sending a message to the java application and each of these messages should have a unique id. From my end I need to make sure every message generated has to carry a unique id so that they can be identified when necessary. All the messages can be cleared every day or two.i am not quite sure about a best method of achieving this. Initially I wanted to create a static method that serves the next available id (incrementing the last id by 1). But this approach willn't guarantee unique number as the application starts only when at least one user is logged on. For e.g .On one server the app starts when a user logs in, he then sends a message and then the application stops when that user logs off. So when a next request for the app comes to that server a new instance will be started.

View 4 RepliesI imported some code I found a few months ago for a client server messaging program from vs2003 and everything appeared to be ok, apart from a couple of niggles such as the windows form designer generated code being visible on the main form code page but i could live with that. I just tried to add a splash screen but when I went to the application tab to set it up there is no enable application framework checkbox and no windows application framework groupbox. I tried running my application again and now the xp visual style has gone and it looks terrible, is there anyway to get the application framework back on again or do I have to start a new project and copy and past all my code into the new project.

View 7 RepliesI was looking to build a Data Access Layer for my new web based application, I'm using ASP.NET. I'm want to build a framework not only for this application but also want to utilize it for my future projects.
Actually my main aim is to make a framework, from DAC, DAL, BL to GUI. I want suggestions from you guys that what should i adopt, what give me flexibility, which suits for both small and large size applications.
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 3 RepliesI am developing an application using VB.Net which is a simple executable which is to be run from a network drive of our company servers. Most users can access this executable without issue - others however can open the executable but have no connection to our database (even though when running the executable off a local drive such as C:, the database works no problem).
From some posts I have seen this might be a CAS issue - however our IT department suggest the issue might be down to different version of the .NET Framework being to blame. Firstly, is this the issue? Secondly, how can I develop my application to work with different versions of the .NET Framework? Surely this doesn't mean developing many different executables?
I have made a simple vb application and have used vb 2010 to create it, which all of you would know, uses .NET Framework 4.0. I wanted to use this application at work, however, I found out that my work uses .NET framework 3.5 sp1.
So my question is, is there a way to compile something in VB 2010 that will work on .NET 3.5 sp1? If so, how?
For a reason I cannot explain, I now get compiler errors from the Application Designer whenever I enable the application framework in the VB.net IDE. I do not find much on this issue, except Scott Hanselman's admonition not to use this feature. I have mature projects in which this feature was enabled, but now even they will not compile.As this only began a few days ago, I have been trying various approaches to resolving the problem, up to and including removing VS2005 and reinstalling it, along with the framework, SDK, and all updates. No dice. The errors are below.This condition will occur even if I enable the feature in a new project.Does anyone have some thoughts and the cause and resolution of this problem?I probably should mention that I was using both VS2005 and VS2008 on this computer. I had been experimenting with 2008 for several weeks without incident.

View 2 RepliesI am developing an application for an emergency services organisation using VB 2008 that will enable users to select a map zone of a city centre and plot icons onto it, then save/export the layered map with icons as an image.My problem at the moment is that I am struggling developing the point where the user imports in the icon (for example, a flame icon where a fire started) and drags it around the map within the picture box to the required area.I want them to be able to select their desired icon from a series of commandbuttons and for the icon to 'appear' on the picturebox and be enabled to be dragged around and dropped as required. The organisation already has such a thing working in Microsoft Word (!) and that uses the ActiveDocument.Shape.LoadImage function on a pushbutton to import the icon and then it is placed on the map as required, but this is really unreliable for them.I dont even know if you can layer images onto an existin picturebox within an application in this way and then export as a flat image.
