After opening a Calculation View, SAP HANA Studio sometimes shows the warning "The object is currently opened in read-only mode. Object belongs to multiple workspaces ..."
If you need to modify the Calculation View it is often possible to take over ownership via a button. But unfortunately this time it is grayed out.
How to fix this?
Work-around / fix:
Check out the file / folder
Edit in Project Explorer view
Activate in Project Explorer view

I'm using PHPStorm 10, every first save after the opening PHPStorm the File transfer tool windows show up, telling me that the file is being auto uploaded.
I've tried all type of settings, without good results: the file transfer window keep showing up at the first save. How can i disable this behavior?
This is the tool window:
File Transfer tool window
Open Tools > Deployment > Options and change Operations logging to "Errors only".
There is no such option in Settings/Preferences.
Just close the window (minimize it) and it will not show up again for this session (only notifications, which you can disable if so desired via Settings/Preferences | Appearance & Behavior | Notifications -- look for "Web deployment" entries).
If you change the View Mode to Undock and drag the inner edge of the File Transfer window outside the viewport, it will effectively be disabled. This is not very elegant and I hope JetBrains gives us a setting to disable this soon.
To see the File Transfer window again, right-click on File Transfer and select another view option such as Dock Pinned.
As of PHPStorm 2019.1.2. Thanks to Erenor's comment for the inspiration.
Edit: Ástþór's answer does work provided none of the transfers are throwing errors. Due to the way a server is set up on one of my projects, it always gives a benign error, which makes the File Transfer window pop up.
Please excuse the noobness that is probably about to follow...
I'm making an vb.net 2010 app which needs to have a calendar system in which the user can add appointments and events etc.
I've downloaded the source for a control which looks promising (http://www.codeproject.com/Articles/10840/Another-Month-Calendar) but I have no idea how to add this in to my project. I've googled for help on adding the control but have had no luck.
If I right click on my toolbox, go 'choose items...' and try and add it there, it tells me it couldnt be opened.
Any help is appreciated!
Well you've downloaded the source code.
Place the source code in a specific location on your pc and then compile it 9If your planning to use this control in your own project then compile it in release mode. Assuming that there are no compile errors close visual studio and then open up the project of your own that you want to use this control in.
Right click on the general tab in the toolbox and click choose items. Using the bowse button in the choose items dialog navigate to the folder in which you placed the source code for the control you want to use.
Now locate the 'Bin' folder and in that locate the 'release' folder. Inside that you will see a dll (named presumably something like MothCalendar.dll. Select that dll and then click add and OK (Button sequence will vary according to vs version). The control should then appear in your toolbox under the general tab and you should then be able to drag it onto your forms for use in your project.
I'm sure there is a simple option for this but I have as yet been unable to find it. Every time I close and reopen Aptana Studio 3 it collapses all the folders in the project explorer and I have to reopen them all, is there a way to get it to leave them open and save the project explorer's state when I close the program?
Thanks.
I cannot find any way to keep the state of the Project Explorer. However, using the App Explorer, the state of your open folder will be preserved. You can also try the "Navigator" which looks just like the Project Explorer, but appears to keep state. I will add the proviso to that: It kept state when I restarted aptana, but it also developed a GUI glitch where it appears to be scrolled to the right so I only see the right half of all of my file names and I cannot fix it, so this may not be a good option if you get the same glitch.
There is also a method which does not do quite what you ask, but may be a good fix for you anyway. If you click "Link with Editor" picture (two yellow arrows) in the Project Editor, it will automatically expand your project hierarchy to match whichever open file you have active. Since your files stay open when you close Aptana, this would keep the Project Explorer expanded to whatever you are looking at even on restart. See this question
You can also set up working sets for various parts of your code that are buried in the hierarchy and use the Project Explorer to show those working sets instead of you projects. This does not save state, but it does give you easy access to common parts of your code that may be deeply buried.
Hope one of these helps you.
In the RDLC report, in Design view in Visual Studio 2008, we don't see anything in the Website Data Sources tab and the button to Add New Data Source is grayed out. Only the Refresh button is enabled, and clicking it doesn't do anything. Our business logic layer returns Lists of business objects and the business logic and business object projects are both referenced by the MVC project. This is an MVC app, so there is no App_Code folder.
How do we get our business objects to appear in the Website Data Sources list so we can drag and drop fields from the object onto our RDLC report?
I think I suffered the same problem as this.
I solved this by closing all open VS windows, cleaning, rebuilding the solution then adding a new WebForms page (yes I know its MVC) but it then seemed to trigger a refresh in something and the data sources showed up when we reopened and editted the rdlc file.
I have also been frustrated by this, using VB.NET, but this should fix it:
In addition to the reference to:
Microsoft.ReportViewer.Winforms or
Microsoft.ReportViewer.WebForms
You need to also add a reference to:
Microsoft.ReportViewer.Common
The Data Sources panel is still blank, but when you select Add Dataset, you'll see the correct options.
Try this...

On the menu bar, choose View, Other Windows, Data Sources (or choose the Shift+Alt+D
I had the same problem in Visual Studio 2008. The solution I accidently found was to do the following:
1 - Launch VS 2008
2 - Open Solution
3 - Open report file (rdlc) and make sure "Website Data Sources" pane is showing
4 - Close VS 2008 (with the rdlc "having focus"
5 - Launch VS 2008
6 - Open Solution
You should now see the data in the Website Data Sources pane
One of the problems I had was that my DataSource class didn't have a parameterless constructor...after the parameterless constructor was added "the class" showed up in the DataSource list.
Small detail, but lost some time to figure it out. :)
Failed to create component 'User Control 1'. the error message follows:
'System.NullReferenceException : Object reference not set to an instance of an object.
at System.ComponentModel.ReflectPropertyDescriptor.SetValue(Object Component, Object Value)
.............. etc..........
What should I do to fix this error?
When a User Control won't load into the Visual Studio designer here is what you need to do. These instruction are for vb.net project but c# should be similar. Also, before doing this close all open windows (or at least the source and designer files of the control you are working on.)
One last thing. The FIRST thing you should do is ensure that restarting visual studio doesn't fix the problem. If not you can try the steps that follow. These instructions assume that the errant user controls are in control library project in visual studio. If not you should be able to adjust the directions a bit to get it to work but it is much easier when the control is in its own project.
Do the following:
Make the control library your startup project.
Open the properties for the control library project and click on the debug tab.
Under Start Action click the Start external program option and browse to the Visual Studio executable.
NOTE: what this means is that when you run your solution it will fire up another instance of Visual Studio instead of actually running your solution. The First Instance of Visual Studion (INSTANCE_1) will "host" a second instance of visual studio (INSTANCE_2) when you run it.
Run your solution. INSTANCE_2 will load.
Switch back to INSTANCE_1.
In INSTANCE_1 hit CTRL-ALT-E. This will open up the exceptions dialog box. Check On the THROWN column checkbox next to Common Language Runtime Exceptions.
NOTE: This will ensure that INSTANCE_1 will BREAK at ANY runtime error even if it is hit in a try block.
Switch to INSTANCE_2. In Solution Explorer double-click to open the errant user control.
You should find that INSTANCE_1 OF Visual Studio should have stopped at the line of code that caused the designer to not load the control. Fix the code (which usually means testing for IsNot Nothing before references an object properties...but could mean other things.)
Also, sometimes I find that the control WILL load in INSTANCE_2 instead of breaking on an error in INSTANCE_1. In that case just stop debugging...close INSTANCE_2. Save/Restart INSTANCE_1 and your problem will often have gone away.
The lesson is this. User Control MUST be able to load/reference all objects and their members in order to load it into the designer. So for User Controls that will be placed onto other containers I will usually design events to notify the parent rather than trying to push objects into the child control.
Hope this helps for future reference on this old question.

Instead of the error occurring when you open up a form for editing, it sounds like this is occurring when you are already editing a form and adding new user controls. A CodeProject article that was previously mentioned shows what to do in the case of a form not loading correctly, rather than a specific user control.
Does your user control have any properties that map to custom objects (i.e. not Integer or String)? If so, the Form Designer will attempt to load your properties into the Property Editor. If showing the properties generates an error, the Form Designer will show that to you. I think this is what is happening with your user control.
If you could edit the question and add more information about the nature of the error (more of the error text), it would assist others in helping you better. Alternatively, see if you can find the property that might be causing the error (e.g. whether any property relies on a non-null value being set). You can also take a look at this MSDN article for tips on how to limit the control for just run-time.
Thanks, Seth, for this post! Your solution helped me nail down the error. The only thing I would add to this is that when "INSTANCE_2" loads, you may need to actually load the project file in INSTANCE_2. I needed to because I wasn't dealing with a control library, but instead had custom User Controls defined in the same project that the forms were located in. Once I loaded the project in INSTANCE_2, I opened the erring form and that caused INSTANCE_1 to pop up to the line of offending code in the User Control.
I have found that this error often occurs when control dlls are not building properly. 95% of the time this is remedied by simply restarting Visual Studio.
