I upgraded my project to VB 2008 and in the designing window, everything looks new and updated. When I run the program, however, it appears to look the same old way it looked in the old VB I upgraded it from. Is there something I can do to make it appear the new way during run time?
View 6 RepliesIf I put this piece of code in a new fresh vb.net form, add a button and two labels and start debug I get execution time of about 11.5s.If I put the same piece of code in a new form in an old project upgraded from an earlier version of vb.net, start debug I get an execution time of 7.5s.So I do exactly the same in the two projects but get different execution times.
What do I have to do with the fresh new project to get the same execution time ?I am not interested in improving the code to be able to calculate primes faster. I just want to know what is the significant difference between an old upgraded project and a new fresh one. I am using windows 7 64bit on a 2,4 Ghz Intel quadcore.

Why upgrading my project from 05 to 08 would stop it from working on any new computer. It will install fine on my computer and users that currently have it installed. I assume it's the crystal prereq issues. It always fails with crystal errors now on install. The prereq's are checked in the properties.
View 1 RepliesI have a VB.NET solution, just upgraded from 3.5 to 4.0. One of the classes has a private field:
Private _Projection As ICalculatedPath.At runtime, any time the class containing that field accesses that field, I get a FieldAccessException. The first time that field happens to get accessed is a null check in a method, and one of the things I randomly tried is changing the above line to:
Private _Projection As ICalculatedPath = Nothing.When I do this, I get the FieldAccessException on that line saying that the class's .ctor() cannot access that field. I've also tried making the field protected and public, clean/rebuild solution, restarting VS, targeting x86 and .NET 4.0 specifically on every project in the solution, and other non-sensical measures to get rid of this Exception but to no avail. This code worked fine before the upgrade, of course.
After upgrading my solution with both c# and vb.net projects I have encountered some problems:
1. When for example writing Public Property MaxDate As Date and pressing enter it does not create the Get/Set values
2. Refactoring is not available
3. The properties window is blank when viewing classes (normally I would see Serializable and COM properties to the right)Intellisense works and the above problems work in new projects.

I recently upgraded to Crystal Reports 2008 for the barcoding functionality. When we use the barcode in the report designer, it renders as expected, so we installed the Crystal Reports 2008 redistributable package on our dev server to test deployment, but we receive the error message listed below. I cannot locate any information about this issue on the business objects site, or azaleas site, or any info regarding deployment of barcoding functionality.

The company has been using Visual Studio 2008 and .NET Framework 2.0 for approximately 2 years. During that time we released several versions (4.x.x) of our program to the public and were able to preserve the user's settings using My.Settings.Upgrade.During the past development cycle we upgraded the program to Visual Studio 2010 and .NET Framework 4.0 and changed the version to 5.x.x. Now, when a user upgrades from 4.x.x to 5.x.x they lose all of their settings.However, in all upgrades after that point (ie 5.0 to 5.1) all the user's settings are once again preserved.I checked C:Documents and Settings<USER_NAME>Local SettingsApplication DataCompanyName and it contains two directories:
ApplicationName_Url_aaa ApplicationName_Url_bbb
where aaa and bbb are 32 character strings. All of the user.config files for the 4.x.x releases can be found in the ApplicationName_ Url_aaa directory. All of the user.config files for the 5.x.x releases can be found in the ApplicationName_Url_bbb directory.Based on this information it seems like something changed when we converted our program to VS2010 and Framework4 that is now causing a different 32 character string to be generated. However, we have been unable to track it down.
We recently upgraded our job server to Windows Server 2008. We have jobs we run manually in a folder (c:Custom Programs). Some programs are console programs others are have a gui. This one program has a gui.It also has a progress bar that shows the progress of the job when you click the go button. Of course it spawns a thread to do the processing. This thread creates a log file to write errors and other things too.
The problem is when the program goes to create the log file an access not authorized error is thrown. I checked the permission on the folder. All users are allowed to create/edit/append/execute. Pretty much everything except take ownership. Also, there's nothing that denies anything. So I see no reason why this isn't working. We can get this to work by using the run as administrator option when we first run the program. However, we don't view this as unacceptable solution. My only thought is the spawned thread isn't getting the same permission set as the program. Am I correct or does something think it's something else.

View 5 RepliesFor reasons that are beyond my control, I have three Projects. Projects A and B reference project C. Project A references project B so that it can open a large form in project B. I now need to open that large form from project C, but VB won't allow me to add a reference from C to B because that would create a circular dependency. I found a way around it, though. I created a Timer in A, and when I opened C from A, I passed in that timer. When the user performs a certain action, I enable the Timer from A, and this causes C to open B for me.

View 5 RepliesI made a change to a project and hve induced a major problem. I have warnings and errors now, but I can still debug the project with the "last successful build" Iwould like to just revert everything to that build but I can't find a way to eliminate the problems I induced or find a way to go to a earlier build. Hopefully I can get back to an earlier version or I will loose the entire project as I can no longer get to the designer.

I'm developing application that is plugable. The plugins are loaded via Assembly.LoadFrom(). In my solution I have 4 projects. A WPF, 2 DLL and another DLL that is a plugin for the app. The plugin project references one of the other DLLs. When I build the Solution and run I was getting an error trying to use the plugin dll because it was expecting an older version of the referenced project. I had to clean and rebuild the plugin project to get it to run correctly.

The matter is that I want to Exit the A.exe and kill the process and the dll that are depending on it. And then Run the B.exe.
I am using 8 different vb projects in one solution, beside this I am also using one 3rd party control ion all the projects, while compiling the application it takes around 5 minutes to build the project, While building the application I have observe that it uses lc.exe file which is used for "Reads text files that contain licensing information and produces a .licenses file that can be embedded in a common language run time executable." at this point it takes too much time.
View 1 RepliesI new to this Forum and relatively new to VB programming. I have read some really good posts here and thought I would ask about a perplexing problem I'm having. I createdindows Form application, built it and deployed it with no problems. However, when I added a small block of code, re-built the app and went to add the app to the Project Output Group in the file system editor the project was not in the Project drop down list. I closed the Setup project and deleted it from the project folder and checked my code and re-built the app and tried the Set Up project again with the same result
View 2 RepliesHas anyone else had issues with Visual Basic 2010?My visual basic program has been running fine for months but recently every time I try and load a project (any project) the program freezes, then I have to close it down and reload, every time I load Visual basic for the second time I get the following error:

An error was encountered while opening associated documents the last time this solution was loaded. Document load is being skipped during this solution load in order to avoid that error.Plus when trying to run a project in debug it takes ages to load (around 5 minutes) this has only started happening recently, projects were loading in seconds.

Having successfully tried out nHibernate, I would now like to try using Fluent for mapping.

View 5 RepliesI have a multi-project .NET 3.5 solution. It's ASP.NET based with c# code-behind in all projects except one.I'm attempting to access members from a C# project called "Core" from a VB.NET project. I set a dependency to the Core solution in my solution properties. However, Core. brings up nothing. Furthermore, my other C# projects that have Core-Project as a dependency (in the solution settings), are able to declare Core objects. Example: Private Core.ObjectName InstanceName; Also, Intellisense brings up plenty of info in the C# projects.how I can hook into these members from my VB project?
