Hello Community,

I am currently using the code below in order to fill my datagridview. However, my datagridview will display columns I do not need to be seen. Also,  I am using Entity Framework 5 DbContext API. DbSet<T>.ToList()

TrialEntities db = new TrialEntities();
dataGridView1.DataSource = db.Resistors.ToList();

When I use the code below to use specific columns I run into various issues with editing from another form back to the main form with a datagridview. This is because in order to refresh my datagridview I call the query again. This causes my edits to be lost, but that is not the case with the previous code above.

var Qry = (from R in db.Resistors
           select new
           {
           ResistorID = R.ResistorID,
           RTC_PN = R.RTC_PN,
           Description = R.Description,
           KeyValue = R.KeyValue,
           SymbolID = R.SymbolID
           }).ToList();
dataGridView1.DataSource = Qry;

Is there a way to select the columns to use without having to select new? Should I be using something other than ".ToList" maybe? Is there a better way to go about refreshing my datagridview that won't lose my edits?

I am new with C# and any help would be greatly appreciated. Thank you!

Hi everybody,

I will be soon deploying a free .NET bench-marking tool [to measure video performance],

but I'm not sure if I should be targeting .NET 4.0 or 4.5 with my tool.

I will be deploying the benchmark program publicly.

Here is the situation:

My tool uses some 4.5 only assemblies [Microsoft.WindowsAzure.MobileServices],

but it looks like I can substitute an upsupported  4.0 alternative if needed.

But my big question is, are there a lot of developers out there who are forced to run .NET 4.0 boxes? Does distributing a 4.5 program scare people in a corporate environment when it asks to upgrade to 4.5? [I understand some corporate environments everybody has to run 4.0 because they are still using XP systems, which will never support 4.5]

Has 4.5 been deployed via Windows Update?

Are there statistics anywhere on 4.0 vs 4.5 installations?

Thanks for any insight or clarification.

I badly need help.  I'm trying to install and load Autodesk 3ds Max 2014 on a windows 7 pc.  The software installs but then when I try to open the application I get an error message saying that it can't open because "a software problem has caused the programme to close".  When I look in the windows event viewer I see the following error:

Event ID: 1026

Source: .NET Runtime

Application: 3dsmax.exe

Framework Version: v4.0.30319

Description: The process was terminated due to an unhandled exception.

Exception Info: System.AccessViolationException
Stack:

I do not know what to do to try and fix it.  I have tried uninstalling the application and unistalling .net using the .net clean up tool (suggested in another forum post) and then reinstalling everything, but that doesn't work.  I have tried using different versions of .net in combination (e.g. 4.5, 4.0 and / or 3.5.1).  But I get the same error everytime.

Can anyone help?  The application is crucial to my work and without it my computer is pretty much redundant!

while convert framework 1.1 application to faramework 4.0.

I'm trying to get a list of all the FxCop rules with a small description of them.

Some more details:

• firstly, after spending a couple of hours going through the forums and the internets, I'm still not sure if FxCop is a different product from the Code Analysis tool that comes with Visual Studio. And even if they are different products, I'm not sure if they use the same rules. I have found this and in the comments section the developer says that it is a different product with the same rules...
• I'm looking for something like this but for the latest (10.0 ?) version since this is quite outdated and for the older version, so I'm assuming more rules have been added since then. Also, even though for most of the rules I can guess exactly what they do from their title, it would be very helpful if I could also find a small description for them
• I've also found this which is exactly what I'm looking for but it is for the Code Analysis tool that comes with Visual Studio. If indeed this is the same as FxCop then I guess my search is over!

Any help appreciated!

Hello all,

I just used NetFxRepairTool to better investigate, troubleshoot a strange .NET Framework issue I found on my Windows XP SP3 client (costantly updated via MU and with QFE fixes only) but, after all time NetFxRepairTool spent to reinstall all identified components (.NET Framework 2.0 SP2, .NET Framework 3.5 SP1, and .NET Framework 4 Full together with .NET Framework 4 Full Language Pack), I've found evidence that NetFxRepairTool was unable to send you the resulting FixDotNet20130613210948597.cab file created.

Here's the evidence I found at end of FixDotNet.log :

...

Is this a problem already known or just a wrong warning ?

If you need me to provide you a copy of same .CAB please let me know where I need to upload it.

Thanks in advance for any help.

Hello all,

after all time spent yesterday on my Windows XP SP3 (always updated via MU and mainly with QFE fixes only) using NetFxRepairTool (KB2698555) to check proper installation status for .NET Framework 3.5 SP1, .NET Framework 3.0 SP2, .NET Framework 2.0 SP2 and .NET Framework .NET Framework 4 Extended and .NET Framework 4 Client Profile (including related .NET Framework 4 Extended ITA Language Pack and .NET Framework 4 Client Profile ITA Language Pack) I've discovered this :

A) Application Event Log contained 6 Event IDs 1001 for removing Performance Counters for following components (older Event is 1st):

- ServiceModelEndpoint 4.0.0.0 (ServiceModelEndpoint 4.0.0.0)

- ServiceModelOperation 4.0.0.0 (ServiceModelOperation 4.0.0.0)

- ServiceModelService 4.0.0.0 (ServiceModelService 4.0.0.0)

- SMSvcHost 4.0.0.0 (SMSvcHost 4.0.0.0)

- MSDTC Bridge 4.0.0.0 (MSDTC Bridge 4.0.0.0)

- Windows Workflow Foundation 4.0.0.0 (Windows Workflow Foundation 4.0.0.0)

B) above Event IDs were followed by 9 more Event IDs 11728 confirming successful setup completion for following components (again older Event is 1st):

- Microsoft .NET Framework 4 Client Profile

- Microsoft .NET Framework 4 Extended

- Microsoft .NET Framework 4 Client Profile ITA Language Pack

- Microsoft .NET Framework 4 Extended ITA Language Pack

- Microsoft .NET Framework 2.0 Service Pack 2

- Microsoft .NET Framework 2.0 Service Pack 2

- Microsoft .NET Framework 3.0 Service Pack 2

- Microsoft .NET Framework 3.0 Service Pack 2

- Microsoft .NET Framework 3.5 SP1

and after all this I've determined that now removed Performance Counters were no more restored and also NetFxRepairTool (KB2698555) completed all its operations while not detecting this.

Is this a new problem for NetFxRepairTool (KB2698555) or expected to happen ?

If such strange effect was expected to happen, is there a quick known way for me to solve and reload again all above listed Performance Counters again ?

Thanks in advance for any help.

When starting any .NET Framework based app I'm getting following error window "Any .NET based programme.exe - Entry Point Not Found. The procedure entry point I_RpcBindingSetPrivateOption could not be located in the dynamic link library RPCRT4.dll"

When I afterwards click on OK software gets started but its annoying that I have to push OK Button every time I want to start some .NET app. I have one even in my startup (Intel Rapid Technologies IAstorIcon.exe) so Windows doesnt load all things on startup cos this error message pops up.

I have Windows 7 64bit with .NET 4.5 withall updates installed...

Any ideas? Thanx in advance!!!

That install failed, so i tried re-installing .net framework Microsoft Visual J# .NET Redistributable Package 2.0 via using the dotNetFx40_Full_x86_x64 package, and also the vcredist_x86.exe package as well. Non worked, same error related to the Microsoft Visual J# .NET Redistributable Package 2.0 which was also pointing towards a missing installation towards .NET Framework v1.1. I attempted to reinstall, and it kept backtracking to more missing versions of .NET frameworks missing.

Now... i also tried doing a verification that i did have the .NET framework 4.5 full, 4.0/4.5 client, 3.5 full variants installed. Their integrity checks checked out fine, and that those .net frameworks were properly installed. So im a bit at a loss, as to what steps i should further take to better ensure my system will work with the Microsoft Visual J# .NET Redistributable Package 2.0 installation.

Heres a idea of my system specs (and all components are updated as of 5/31/2013)

If anyone can give me a idea what im doing wrong or what i should install, and in what order, please do list so, and list step by steps, like ex: "Install this here LINK LISTED" and then afterwards install this package next LINK HERE," and so forth, so that i have a idea what to do, and how to further more install in what manner to do such so that no errors will occur.

.NET Framework 3.5 installer just extracts then deletes the extraction destination.

GOT AN ANSWER TO THAT?

Hello,

I have this issue where .net framework 4.0 keeps rolling back it's installation. For the past few days, I've been searching and troubleshooting various methods to this problem which includes:

• Running as administrator
• Running the program in a secondary administrator account
• Using the dotneffx_cleanup_tool
• Cleaning the temp folder after each installation attempt
• Used a microsoft fix it program
• Used the windows update
• Checked and changed permissions to the registry
• Tried the full setup and client setups
• Removed, restarted, and attempted re-install of  .net framework 4.0
• Attempted to install other versions of .net framework such as 3.5 but didn't work
• Checked my windows update history to see that majority of the failed updates even in the past few months are .net framework 4.0 updates
• Restored to an earlier Windows Restore point

The thing is, it has only been a few days ago that my computer has been working flawlessly for months. My programs that utilizes .net framework 4.0 has all worked fine. After that, I don't know what triggered it, but my computer just doesn't accept the idea of .net framework in its system again. I've scurried as much topics as I can related to troubleshooting this problem, and I'm not sure where else to look. 

Here's my log, I hope more people can make more sense with this.

Hello all,

is anyone aware of a known way to solve "RegAsm : warning RA0000 : No types registered" error ?

Background for this issue: after checking proper installation status of .NET Frameworks on my Windows XP SP3 (constantly MUed and mostly with QFE only fixes, I only miss v1.0 and v4.5), both NetFxRepairTool.exe (KB2698555) and netfx_setupverifier.exe found no errors, inside %windir%\Microsoft.NET\Framework\v4.0.30319\ngen_service.log I've found 11 errors similar to these:
...
06/16/2013 23:09:59.292 [888]: Failed to load the runtime. (Exception from HRESULT: 0x80131700). Assembly Microsoft.BackgroundIntelligentTransfer.Management.resources,Version=1.0.0.0,Culture=it,PublicKeyToken=31bf3856ad364e35,ProcessorArchitecture=msil requires version v2.0 of the runtime to run.

Assembly will be compiled once the correct runtime is installed.
...

So to solve error 0x80131700 I've already tried known solution also described into KB2252691 :
...
32-bit Server

1.       Open a command window
2.       Go to C:\Windows\Microsoft.NET\Framework\v2.0.50727
3.       Type: regasm “Full_path_to_involved_dll”
...
but everytime I did so I received back the message "RegAsm : warning RA0000 : No types registered".

So any clue, suggestion or ideas to be sure to solve all this ?
Thanks in advance for any help or advice.

Best Regards
Rob

We are building a client application and working with .Net 4.0.  Our data analytics show that around 50% of our client base still uses Windows XP and therefore cannot get the .Net 4.5 update, so we target .Net 4.0 in Visual Studio.

Our testers have notices a few differences between running our app on a Windows 7 (Or XP) PC without .Net 4.5 vs a Windows 7 PC with .Net 4.5 installed.  Infact, in one case it works as desired in the PC's with 4.5 installed, but here's an issue of dissapearing buttons on the .net 4.0 clients.

As developers, we are enjoying taking advantage of the new features in VS 2012 and some of us run Windows 8.  As a company though, we have to support a client base that has mostly windows XP users, then win 7 and some are now on Windows 8. Ultimately, we need to know when developing, areas where we are likely to see differences, so we can adapt our code accordingly and direct testers to areas of concern, so we can ensure that clients get the same experience, with or without .net 4.5.

Have Microsoft published anywhere a list of changes and bug fixes in the 4.0 framework between the .Net 4.o download and it's updates (e.g 4.0.30319.1) and the newer versions that come with .Net 4.5/VS 2012/Windows 8 (e.g 4.0.31319.17979 - 4.0.31319.18047)?

Can't Install .Net framework on Windows 7 and Windows Xp pro i have error log which installer gives

Error log

Hey there, I seem to be having an error isntalling .net framework. I'm running windows 7, 64 bit.

The installation log is as follows:

Any advice?

I've had a problem with not being able to uninstall, download or repair .Net Framework 4 after I had an update for it somewhere around January this year which made my computer restart and install the very same update over and over again until I started to hide the updates since most of the programs that I used until now didn't really require it but I have these last few days been looking for ways to fix it as I have some very important programs that do require it but I can't seem to fix it anyway I try, I even used irarabi's fix but that didn't work either so here's the error code:

Hi i have .Net Framework in 4.5 in my computer, but when i try to run a program it says that i need a 4.0... version in my computer, i tried putting that version and didn't work so i installed 4.5 again.

My computer has Windows 7 professional x64.

I did go for windows update and there was nothing to .Net Framework.

What can i do about it???
