Are you sure you haven't left something running in the background - e.g. stopping the program in the debugger and then trying to run it again?
Try closing Visual Studio and opening it again. Try Cleaning the project - or manually deleting the contents of the bin\Debug (or bin\Release) folder
|

|

nope , killed all processes, tried cleaning , if i restart its fixed until i debug / run it more than 2 times, so it somehow stays open while hiding itself i guess, because in the task manager theres nothing, neither in processes

Is it using a resource that isn't being disposed of properly?
|
|
|

im still new to most of this, how would i check to see if its using a resource thats not disposed of properly??

Review your code 
For example, have you opened a connection to a database without using using or closing the connection when you're finished with it? Ditto using Excel/Word via interop.
The only other thing I can suggest is comment out tracts of code, prove the problem has gone away, then uncomment a section, run again ... repeat until the problem re-occurs and you will have at least located the section causing the issue.
There was a version of VS I used a few years ago that kept leaving the vhost in Task Manager - I had a pre-compile step that killed the process. The problem went away after the latest patches were applied, so make sure you have applied all of the patches (if any) for your version of VS

thanks ill get back to double checking right away and ill also check for available patches. thanks alot,also im using the VS 2015 RC edition if thats worth something 
|
|
|
|
|
Far more recent than the version that gave me grief  In which case, check that code. Good luck
|
|

i fixed it but dont know what is the problem, basicly the program stayed open even after using the red x to close it, so i created a button with the aplication.close(); ,,, its a workaround until i get the real problem
|
|
|
|
|
I get this all the time and assume it is a bug in VS, closing VS usually clears the connection. It is a PITA but I live with it!

hi i want to create a inventory management system,
my problem is in sql server 2012 , i created a database, i created a table named
products(varchar (50))
in my form c# i have a quantity/name/code/cost price/sell price / and a add button, how do i get those datastructure into sqls
|

That is not the way to create tables. A table should contain columns which relate to the data items, i.e. quantity/name/code/cost price/sell price etc. There are many samples and tutorials at http://www.codeproject.com/Chapters/4/Database.aspx[^] which will help you.

I think you're asking for the statements that go in SQL?
If so, there's an easier way to create a database in SQL server.
1. In object explorer,Simply right click on "Databases"
2. Select "New database"
3. Give it a name then click ok
4. Thereafter, expand the databases folder in object explorer to find the db you created.
5. Expand your db and right click on"Tables" to add your tables.
Hope this helps

Hi,
I've got here a project for a lab-test software for internal use, which has a lot of buttons. It has a main form and some tabs which all have a lot of elements. This results in a lot of event handlers in one file.
Is there any good method to devide this (I thought about a file for every tab )? I tried this with partial class and it did compile (couldn't test if it also really would work) but when trying to jump to one of the handlers in the code editor it always jumps to the original file and sometimes even creates a new empty handler, that's why I dought that it really works.
I don't want to reduce the number of buttons, it is the easiest way of triggering a function also for untrained personnel.
Any hint to this ?
Thanks very much

The way I would do it is to create a UserControl for each tab page - that way, the number of controls on the main page is reduced to the minimum, and the interactions between the various controls become more rigid and defined - which helps a heck of a lot with maintenance.
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

I am trying to create a TableAdapter in a DataSet using the "table Adapter Configuration Wizard" in Visual Studio 2010. I am connecting though ODBC connection[DSN connection], the SQL query runs fine but the fill method is showing error "HY010[ODBC][ORACLE] Function Sequence Error".
But When I am doing same thing using Oracle client connection then it works fine but since its deprecated, i want to use ODBC.
Any help is much appreciated.

Why do you want to use ODBC? It's a generic and unoptimized method for getting at databases. Being generic, you lose the performance benefits of using a direct client and you also lose database engine specific functionality.

What is deprecated? ODP.NET? No, it's not.

Microsoft's Oracle client (System.Data.OracleClient) is deprecated:
The types in System.Data.OracleClient are deprecated and will be removed in a future version of the .NET Framework.
As you say, ODP.NET[^] is still supported. It's even available on NuGet:

Hi Richard,
Thanks a lot for guiding me.
Is it possible to share an example of creating table adapter using ODP.net
|
|
|
|
|
I've never used Oracle, so I'm afraid I can't give you any examples.
If you're using the wizard, you apparently still need to install the developer tools[^]. With those installed, I'd hope that it would be fairly straightforward to create a table adapter.

Is there any nuGET package for ODBC?
|
|
|
|

No, the ODBC classes ship as part of the .NET Framework.
Why would you want one anyway, since your question says your code doesn't work when you use ODBC?

The issue is several other classesin the application depends upon a web service which uses ODBC connection to connect to DB. so for this table adapter is I create a ODP.Net, either I have to change the webservie code along with all the classes or the option I am considering is re-write the code with DataAdapter instead of tableadapter thereby eliminating this connector issue
