Performance Related Features For Migration From .net 2003 Framework 1.1 To .net 2008 Framework 3.5?
May 21, 2010
I am work on VB.net 2003 Framework 1.1 for last 3.5 years in windows Application.We are currently migrating to VB.net 2008 framework 3.5, but i don't know about the features which related to ADO.net and which is important to performance. I know linq to SQL but our architecture is made in .net 2003 so we should follow this.Any features which is very important to enhance the performance?
I made a program a month ago and i gave it to the customers.recently they report some bugs and i fixed them. when i send the new version installer to them, they have some problems running it.i used vs 2008 to write it, but i removed vs 2008 and installed vs 2010 last week. when i opened my project to start fixing program bugs it asked for convert wizard so i did it.i made changes and build it. i use installshield and i add framework 3.5 Sp1 as prerequisites. note : i was using inno setup first time. so i changed the installer too.so i tried installing the program on my machine.i just noticed that i have only .net framework 4 installed my own system. so i have no idea how the program runs without any problems on my own system. i have even tried installing it on another machine who had framework 3.5. it it work on that too.the error shown on customers machines is related to framework version. everytime i send them a new version they have some problem installing/running it.
Is there any way to use the new dynamic features in the 4.0 framework like ExpandoObject in VB.NET without setting Option Strict Off? With C#, you lose type safety only with the variables you specifically declare as dynamic. But with VB, the only way I've found to use these features is with the old Option Strict Off trick that's been in VB.NET since the beginning. Without Option Strict, everything in the file is polluted with fuzzy typing like so:
Option Explicit On Option Strict Off Option Infer On
[code]....
what's the best way to still use things like ExpandoObject and mitigate the risk of losing all type safety? Partial classes?
I've been asigned to a new project. I have to mantain an application wich was made in Visual Studio 2003 (VB.NET, Framework 1.1) and Crystal Reports wich came included with the IDE. The application is absolutely what we call "legacy code" :).Just to make the test, today I've tried to convert the application in Visual Studio 2010. The converter is offering me download SAP Crystal Reports, with no cost and no registration.The question is: Does anybody has experience with this components?. Is feasible to migrate an application as described to VS 2010?
I want to drag-and-drop a Word Document 2003/2007 control in my form by .NET Framework. Like we do for PDF in the following screenshot. If you see the highlighted text, it is Adobe PDF Reader. I can show the PDF documents in this control in my form.
I am upgrading from Visual Studio 2003 to Visual Studio 2008. ow I should upgrade my project.My project is in Visual Basic.Net, and using an Access 2003 Database. I have four datasets, MainDataSet (for the main data tables) LookupDataSet (for lookup tables States, Countries, Colors, etc) OneFormDataSet (data used on only one form) and ReportsDataSet (data used for reports).I have one form "OleDbAdpatForm.vb", that has all the OleDbDataAdpaters for my project. It also has the DataSets and the OleDbConnection.I have public functions that enable me to load the data tables.
I have a LoadTable function when I can pass a column and a value, and the SQL select command is updated with a WHERE or HAVING, so only the requested data is selected. I also can pass the whole "WHERE ..." part of the SQL select command, so I can have multiple parameters in the SELECT command.On my other forms, I have copies of the DataSets, so I can design grids/controls. In the form_Load events, I manually bind the controls to DataSets and tables in located "OleDbAdpatForm.vb", so all forms are using the same data tables, and changes made to data in one form are reflected in data in other forms.The VS 2008's DataSources, BindingSources and TableAdapters seem much easier to use. how I should implement the new data features in my application?
I have a solution that I wish to upgrade from Vb.net framework 1.1 to framework 4.0. The solution consists of a number of projects, all but one of which compile to dll's. The master project compiles to a executable which provides a menuing system which dynamically loads the dll's and connects to entry points.
The projects contain normal classes, numbers of forms and also controls, which are either usercontrols or are inherited extensions of standard windows controls.There are a number of third party components (eg reporting and grid controls from Component One, Ribbon control from DevExpress etc).
How come software created in an older framework version won't run on a newer framework version? Actually whenever i try to run some old specific software having .net 3.5 framework on my PC they show they needs .net framwork 1.1 . What a bad thing?My newer version of Photoshop ans Ms office open all lower version files.
I work for a small company and we are planning to build our own framework using .net . For example if a dropdown is placed in the form and set the custom property to Users, then the users list from db from has to populate. The developer will drag and drop the custom control and set the connection string in config file. Other things are to be managed by the framework.
I have a application VB.net which is working fine for office 2003.But one of the user has installed office 2007.I dont have the knowledge of BindingRedirect .
I recently tried to reinstall visual studio 2008 Prof. But every time I start theinstallation it fails after installing the .Net framework 3.5. The framework doesn'tsucsessfuly install and it gives me the 1603 error. I think I have the .Net framework 2.0 running right now but the setup for that gave me an error to but it is in add and remove programs.
i developed a program using vs 2008 and works well. now i want to distribute to my friends for that which version of .net framework i have to give along with this?
I need to detect if any version of the .NET framework is installed as we are deploying a .NET 2.0 app via logon script (ie XCOPY deployment) to all PCs in our network. The .NET app will be set to start when a user logs in, so we need to determine if .NET 2.0 (or higher) is installed before we deploy the app otherwise the user will get an error each time they log in. Is there any sure fire way to detect .NET via vbscript or batch file? All of the results I have found on google don't seem to be that reliable.
I have recently written a program that detects installed programs in the same way that Add/Remove Programs does but the problem with this is that even Add/Remove Programs does not seem to show the .NET framework on all PCs that have got it installed (like my home PC for example, definitely has .NET 3.5 installed but its not in the Add/Remove Programs list).
I'm writing a code that will check if .net framework 3.5 SP1 is installed before installing the program.The command I found googling around was System.Runtime.InteropServices.Runtime Environment.GetSystemVersion..I wasn't able to verify the correct .net framework version using this command.I'm currently running 3.5 SP1 and this command is showing v2.0.Is there another way to get the correct .net framework version?
I have a clickonce application that's already deployed to ~30 machines with .NET framework 3.5 as a prerequisite. I now want to remove the 3.5 prerequisite and opt for a 2.0 prerequisite without messing up my existing installs/deployments.Are there any pitfalls in doing this that I should know about? I really don't want to have to force all old users to re-install.
I developed an app using the .net framework 3.5 sp1. I have now been told that the published version must not require sp1 but just the 3.5 framework.
So I uninstalled sp1 from my pc but not cannot publish the app. The app code will run without error but when I build it for publishing I get the error The "RequiresFramework35SP1Assembly" task was not found. Check the following: 1.) The name of the task in the project file is the same as the name of the task class. 2.) The task class is "public" and implements the Microsoft.Build.Framework.ITask interface. 3.) The task is correctly declared with <UsingTask> in the project file, or in the *.tasks files located in the "C:WINDOWSMicrosoft.NETFrameworkv3.5" directory.
I was messing about with my code when I recieved some errors, I deleted some stuff but I don't know what but it fixed the errors I was getting but now the Enable Application Framework section has gone..
Is it possible to reduce the version of .net framework of my application. For example: Host using my application have .NET 2.0 I make changes in my app so that it always run as .NET 2.0 not the latest .NET 3.5
Or another idea i have is to deploy .NET 3.5 in installation package i.e. if he runs my app and it detects .NET version and if its not .NET 3.5 then .NET 3.5 installer should open else my app should run.
I am facing problems these days. I have VB Express 2008 with 3.5 .Net Frame Work. I develop applications but my applications dont run on the systems those have 2.0 framework or lower.How can I make my applications to run on all kinds of systems
i get a lots of errors with my application because users doesn't have the .Net Framework installed so i was thinking, can't i take every .net framework resource that my application uses and needs, and add it as a reference in my application so that the user does not need to install .Net Framework?
I am deploying my application. As the .Net framework needs to be installed on the user's computer. Is it possible to pack the .Net framework into my executable setup.exe?
This will make my setup.exe big. However, the client doesn't mind.
I want to test out a code line with about 50,000 characters over about 7 lines, but VB takes about 2-3 minute breaks for every line of code I change and it crashes every 1-5th try. I moved the code into a public shared sub in a new class, and closed the class tab, but still VB can't resist checking though the code all the time.Is there any way I can prevent VB from checking that class/code?
how to add other version of .net framework. like 1.0 or 1.1 .net framework here is my problem i deploy my application, when i install, it always say to download or install the .net framework. i want to run my application under windows xp cause our client does not update their machine.
I go to install visual basic 2008.. and it says that an error has occurred. and that .net framework 3.5 could not be installed? I've tried other programs like visual studio and visual c++ and they all do the same thing. and i've also tried directly installing the framework and it still wont work. Sorry if this is not the right place for this post but i couldnt find a tech support forum?
I'm running some unit tests for a large VB.Net application I help maintain and am running into problems with tests timing out. The test run is set up so that there's no timeout limit on the overall test run, but a limit of 2 minutes per individual test. However, a couple of the tests take a lot longer than this to run, so we tried adding the timeout attribute to the test's declaration, i.e
<TestMethod(), Timeout(15 * 60 * 1000)> Public Sub DoSomething()
for a 15 minute timeout. However, the 2 minute timeout set in the test run properties seems to be taking precedence, even though it says that the timeout attribute should override it.
I'm trying to develop an app with Microsoft's Visual Basic Express 2008 to run on the .net framework 1.0. Is there something I can download to do this or do I have to require the latest framework to be downloaded?
When you develop a class library that will be used by others, are there any guidelines on how you decide what namespace to put it under? I often find third party classes just use the company name as the root namespace but I was also wondering if it is frowned upon (or even possible) to add one of your own classes to an existing framework namespace.
