I am confronting the following error:
I need help please. Thanks in advance.
I have solved the problem by excluding a project form. All forms used in the project are cloned. The truth is I don't know if this influences anything, or there is a paid version of Visual Basic that doesn't limit the number of duplicate forms to use. The project did not create the executable file when trying to run it. I had to create a new form and duplicate the others from this one so that it would continue to work. Thanks a lot.

I am moving a solution with multiple projects to VS 2015. The base project builds just fine in VS 2013. But when I try to build in VS 2015 I get the error below.
C:\Program Files (x86)\MSBuild\14.0\bin\Microsoft.VisualBasic.Core.targets(56,5): error MSB6006: "vbc.exe" exited with code -2146232797.
Need help please
I talked with MS Tech Support. It's a confirmed bug in the VB compiler. They say it will be fixed in the next update.
In the mean time the work around is to install a Nuget package.
Please follow these instructions to install Nuget package.
Open the affected project in Visual Studio
Open the Package Manager Console (Tools -> NuGet Package Manager ->
Package Manager Console)
Run:
Install-package Microsoft.Net.Compilers -version 1.1.1
I had a large solution that was failing to build after updating to VS 2015 Update 1 RTM. In my case, there were a number of warnings of
Namespace or type specified in the Imports '<import name>' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.
that occurred right before "vbc.exe" crashed. Once I removed those extra, unnecessary Imports, the solution build correctly.
This issue is resolved in the latest Visual Studio 2015 servicing update. The relevant download is KB 3110221 which is discussed in this KB article.
In my case, I found that an import was causing the issue. Specifically, after trying a lot of other suggestions, removing the Microsoft.Office.Interop.Excel import from a file, finally got my project to built.
I had the same issue after installing Update 1 to VS 2015.
I've download Microsoft.Net.Compilers NuGet package as Brien King suggested in his answer. This fixed the issue for one project. And then:
"c:\Program Files (x86)\MSBuild\14.0\Bin\vbc.exe" had version 1.1.0.51109
...userprofile.nuget\packages\Microsoft.Net.Compilers\1.1.1\tools\vbc.exe had higher version 1.1.0.51202
So I've copied entire "1.1.1\tools" directory into "14.0\Bin" directory and overrided 27 existing files.
This fixed it for all projects. Remember to create backup before you do this.
After trying both Microsoft.Net.Compilers -version 1.1.1 and KB3110221, my solution was still failing to compile with the same error. Only later I noticed that the error was accompanied by a warning which was letting me know that one of the libraries referenced by the solution was compiled against .NET Framework 4.5.2 while my solution was compiling against .NET Framework 4.5. I recompiled the said library against .NET Framework 4.5 and the solution compiled fine.
Now that my issue was solved after trying three fixes, I can't tell whether the last one alone would have done, but I hope it'll be of help.
I fixed the issue by opening all my .vb files are removing extra imports. Do this for all files and then rebuild. This should work.
I started getting this immediately upon installing vs2015 due to a licensing disagreement w/ MS , which I lost. :-(
Freshly back to work, i encounter this issue.
I tried doing the NUGET suggested by Brien King. Problem persisted.
I tried doing the KN suggested by Teodor Constantinescu. Problem persisted.
I tried a new trivial web app and things were fine, so I did not uninstall vs2013 or vs2015.
I chose to back up my project (3 times, once on a usb stick i put in the other room) and delete groups of files and compile after each group was pulled out.
Ultimately, when I got close to the end (nearly an empty project) it compiled.
By adding groups of files back, I identified the single file that causes this issue. I can recreate the issue by uncommenting a single line.
Further commenting out code, I isolated the problem to 4 lines of code. Beautiful.
Explanation is this...
I have 2 web references that reference ssrs
THese are currently defined in my project as
SSRS_reportservice2010
and SSRS_ReportExecution2005
I struggled getting these to work, so over time i had different names as i deleted and readded the web references. (Padawan)
For whatever reason, a file that was EXCLUDED, got INCLUDED today (2013--> 2015 issue, or greg mouse farting issue? we will never know)
In that (mistakenly included) file, there was a pair of old references
'1 Imports SSRS_ReportingService2010
'2 Imports SSRS = SSRS_ReportingService2010
'3 Imports SSRS_ReportExecution
'4 Imports SSRS_E = SSRS_ReportExecution
Line 1 used to reference the WS now named in my app as SSRS_reportservice2010
You can unComment that and things compile and run. Note that you do get a warning that you are referencing an empty namespace.
Line 2 is of course an alias to the long name, because I am an extremely lazy typer, plus I insist my code be readable and long names stink IMHO.
Line 2, if uncommented , cause vbc error -2146232797
Note that uncommenting 2 , or 1 & 2 cause the error. Its something about the bad alias that causes compiler upchuck.
Repeat the above discussion with lines 3 and 4 which have to do with the webservice currenlty named SSRS_ReportExecution2005
So there you have it.
This took me 8 hours to debug. hope it helps someone.
Many of the other posts, comments, etc also mention Import/Using Statements. The root bug probably lies somewhere in there.... (yes, this is a bug in the compiler)
PS - one thing that was interesting is that the offending file's name started w/ a W so was one of the first to come out.
Nothing improved when I took that file out of the project all together.
I can not explain why the app did not compile as soon as I took the offending file out.
I can offer that I took the webservices out very late in the process, I just didnt think they were the issue.
It baffles me that the file could be gone and I was still getting the issue when I can now simply comment out 4 lines and things work perfectly.
Apologies for the second answer, but this one is much simpler.
I got the error again in a different project 8 days after last time.
This time, I started the day by giving a better name to a class.
I had a class named conversionFactors and I renamed that class to constants to better represent what the class held.
Immediately got the error
vbc.exe" exited with code -2146232797. SizingEngine
tracked it down to this line. I should have used the rename utility. yes. No argument. The compiler should also be more robust. Tsk tsk Microsoft.
Imports cf = SizingEngine.conversionFactors
so steps to reproduce
1. create a new project
2. create a class named Foo
3. create a class named Bar
in Bar, add the following line
imports bar_ = project1.NoClassByThisNameExists
click f5
listen for pac man wilting sound
ps - VS does not report any updates ready for download today. Im sure this will get fixed at some point.
I've just had this same issue. Mine was caused by having a class that had an event inside. I'd referenced this in another class as a shared property. The shared property was causing the compiler to fail. I removed the "shared" declaration and it compiles fine now
I encountered this error when I had a post build event that was throwing an error.
There was no indication this was the problem, just the -2146232797 error.
So check this in the property pages of the project. Go to Compile -> Build Events ... and check the Post-build event command line field. I suppose this might happen with a Pre-build event so check that as well.
The problem may be related with some utilized function in .NET Framework. Try to change the project framework to 4.0 and see if the problem persists.
Whilst loading up new resources to Visual Basic 2010 the IDE crashed half way and when I restarted it and tried to execute my program I get
Resources is not a member of my
Could anyone help me figure out why the suddenly no more exists. Could it me a missing file? If so, which one.
I noticed that the size of resources.resx file had shrunk, so I restored a previous version from drop box but im still getting
Resources is not a member of my
What other files could have possibly been affected and what would the purpose of these files be fore future reference.
Thanks in advance!
I figured it out by watching the task manager. Seems the system was running out of memory on start up. I removed some surprisingly large resource files and this seems to have resolved the issue.
I've got a really strange error and any light that anyone can shed on this would be greatly appreciated.
I made some changes to some VB6 source which builds a COM object. The automated build which builds our app returned an error. No problem I thought--I'll just back out my changes. Well backing out my changes isn't making the problem go away.
Specifically when I attempt to build the app via a .vbg file, with a command line like path\to\vb6\vb6 ProjectFile.vbg /make
I get a message
"Compile Error in File '', Line : Object library
invalid or contains references to object definitions that could not be
found."
As I said, I reverted the source code so I'm really stumped as to why this error is still occurring. Any VB6 gurus around who might be able to point me at an answer?
I can post the exact code in question but the fact that it was building correctly, stopped building correctly and now refuses to build correctly makes me think this is not a problem with my code but rather some problem in the environment. Like something got put in the registry as a result of the previous build error.
Any tips, hints, or suggestions greatly welcome. I realize my question is a bit sketchy but I'm not even sure what's important to include and what isn't.
EDIT 1:
Thanks for the excellent suggestions guys. I think it is something to do with VB6 doing some sort of auto-registration.
Just to add a bit more detail: this problem does not occur when I build the referenced vbp file from the IDE. It only happens on the make on the .vbg which contains the vbp. Also the build tool in question automatically pulls latest source and the error happens on both my local box and the dedicated build box.
EDIT 2:
Hi again all,
The release engineering fellow figured out how to get this to build in his build environment so it's currently ok. Once we're past this crunch, I'll try to interrogate him about what he did and share the details with everyone.
Thanks again for all the great suggestions. This is what's so great about SO; that is, I asked about a 10-year-old technology and I got several great and on-point ideas.
Make sure that the VBG and all the VBP's got rolled back as well. That error is consistent with a project trying to reference a CLSID that is no longer valid for the dependency. Have you tried loading up the project group and building from the IDE, if that works and you save and check in all the changes to the group and project files, you might be fixed up.
I'm guessing the fact that you mention that it was a COM component might be the source of the problem. If any of the public method's or properties have changed then I seem to remember that VB6 will change the interface GUIDs and auto register the new ones.
My suggestion would be to check the registry to look for any mention of the component name, make a note of any associated CLSIDs, back up the registry, and then delete the references.
As cmsjr mentions it could also be a bad CLSID reference in your .vbp files.
The other option is that the failure has caused a problem with some .tlb (type library) or olb (object library) files.
The best thing to do is move all your compatibility DLL to a separate and combined directory. The reason for this is control over what VB6 is using to check for binary compatibility. In addition the Typelibs that are generated IMPORT the references. So if you using Binary DLL Ver 10 for compatibility however the import is pulling in Binary DLL Ver 9 you will have issues. By keeping all the libraries in a single folder and pointing your projects to the DLLs in that folder you ensure that the respective TypeLib Import the correct version.
Finally if you have multiple levels of DLL reference each other. You may run into mysterious error where the VB6 is unable to compile using binary compatibility. In such cases you need to compile the lowest DLL in the hierarchy (Utility DLL perhaps) copy it over into the compatibility folders. Work your way up the chain until everything compiles in one shot again.
This is because if have DLL A reference DLL B which Reference DLL C. VB6 will get sometimes get confused if you make a change to A and C. will compile fine but A will not until the compatibility libraries are updated.
Hunt down and delete any .obj and .exp files that may be lying around from the previous failed build.
You will have to open the project & re-type in the lines that you changed.
Save the project alongwith VBG and re-compile after that.
I think that will fix it.
EDIT: The idea is that the cls/bas file remember the class (CLSID) that you used. So, if you change the references but don't change the lines in the cls/bas - it is a mismatch of type (what was referenced vs what is typed in cls/bas file).
I admit...I am posting this question because I still don't have an answer to my other question and thought I would take a different tact.
Can someone explain to me WHERE the values for intellisense and namespace/class/member completion works. I figured if I can drill into where/how it is deriving that data I can try to reconfigure my project so that it will resolve my namespaces correctly.
Seth
The name space and intellisense information, for the CLR, comes from a database hidden inside the VS install.
The information for the working project, is scanned and archived (I think in a file) when you open the project. It then periodically updates it as you work.
If you want the exact path, I doubt that Microsoft publishes that information.
After looking at your other question, I wanted to add that it is possible (somehow) to have Visual Studio rebuild the index information for a given project. It eludes me on how to do this right now. Have you tried this and did you end up with the same results?
Update in regards to comments:
Refreshing the cache is easy but not
necessarily obvious. There are two
ways to refresh the cache: 1) Go to
Edit -> IntelliSense -> Refresh Local
Cache and 2) Hit Ctrl+Shift+R
Source: Dan's Blog - Refreshing the IntelliSense Cache
I don't know how it's done in Visual Studio, but here is the general approach:
Collect all the public members and methods.
This is done, in case of managed libraries like those produced by VB.NET, by reflection. The documentation comes from xml files related to those libs. That's the approach for Referenced libraries.
For the project you are currently working on, it just constantly parses the source files where the documentation is combined with the code.
How the namespace resolving is done depends on the language offcourse, but that is answered in your other question.
I realize this question has been asked before, but I was not able to find anything that worked for me yet.
Things I have tried:
Switched settings back to default (mulitple ways)
Project Builds/Compiles fine
Closed VS and restarted
The only thing I haven't been able to try is deleting the ".ncb" file, but that's only because I can't find it. In fact not a single one of all our projects have such a file!
So the first question is why can't I find this file in the solution's root directory? The only file I have there besides the .sln is the .suo.
Then if that doesn't work what other options do I have short of un-installing and re-installing?
As for how it happened this might help. While using VS2008 and VSS6.0 (yuck) I made a number of changes to a lot of files via Find&Replace that I didn't mean to(had Entire Solution selected instead of current document). To undo the changes I exited without saving, reopened the solution, then Undid checkout. After that I lost intellisense! I can't imaging how they're related but it might help.
Thanks,
Jeff
IntelliSense usually stops working when it can't compile correctly. Try a new simple project from scratch and see if it works, if it does you have your answer.
Is this for C++ code? If it is, my suggestion is not to try fixing built-in IntelliSense at all, rather try some 3rd party replacement. My favourite is definitely Visual Assist X, which is lot more robust (it almost never stops working, and it is able to parse even very complicated templated and preprocessed stuff, which often makes IntelliSense "lost".
Visual Assist works with other languages including Visual Basic, however this is something I have no practical experience with. Still, there is a free trial - you may try it, I expect it will be superior to IntelliSense even for VB.
Answer:
I figured out how to fix it. Apparently while I was undoing those changes I somehow excluded the file that I wasn't getting intellisense in from the project.
I just right-clicked on it and said "Include in Project" and viola! Intellisense worked again.
Sorry for the false alarm but I appreciate the effort.
Jeff
