How to in c++ 2010 builder show hint all the time when is code write?
For example if I try to use command MessageBox, I start to type message and press control+space, that will be show up list of functions which have first letter same, and after that I press enter on which function I like and that give me a yellow hint, everything is ok therefore I press backspace or make error in spelling that hint then disappear. So my question is how to force that hint message to stay guiding me all the time (like in Visual studio)?
Place cursor after '(' ans press Ctrl+Shift+Space to redisplay hint.

In eclipse when you hover over some erroneous text you can press F2 to focus there. What is the equivalent procedure in IntelliJ?
Whenever I put my pointer over some error the text describing it disappears.
In Eclipse it will suggest what I can do to fix something like an unhandled IO exception. I'm sure IntelliJ can also do this because some people I know who are quite skillful programmers highly recommended it to me, but- how to do this?
That is: hover over some text at is in error, see what the error is, the options to fix it, and then choose one.
If you click on the highlighted part of code, the error description will appear in a pop-up bubble as well as in statusbar.
You can then hit ALT+Enter which will offer you some options to handle the given error/warning or to disable the warning.
The actions you are looking for is called "Error Description" and "Show Intention Actions".
⌘+F1 (Ctrl+F1 on non-mac) will show the error info on based on where the caret is.
Alt+Enter will show the Intention Actions available based of the location of the caret.
Apologies upfront if this is a silly question, but it's annoying me to no end and I can't figure it out.
I'm using Visual Studio 2013 Professional, and I usually code in C# where when using the Intellisense, when I press Enter to select a method or something it adds my selection and I can continue typing on the same line.
But at the moment I'm working on a project which is in VB.NET, and when I use the Intellisense in the same way it puts my cursor in the next line, i.e. I press Enter to select whatever, it adds my selection and starts a new line, so I have to press the Backspace to go back to the previous line. It's so annoying!
Is there a way to change this behaviour so the cursor doesn't go to the next line? I've looked at the settings available in Tools > Options but can't figure it out, and searching Google for anything similar hasn't been successful.
Found it here (paragraph List Members)
You have toggled to suggestion mode instead of completion mode.
You can also change to suggestion mode, in which only the text you type is inserted into the code. For example, if you enter an identifier that is not in the list and press TAB, in completion mode the entry would replace the typed identifier. To toggle between completion mode and suggestion mode, press CTRL+ALT+SPACEBAR or click Edit/IntelliSense/Toggle Completion Mode.
So, either use TAB/SPACEBAR (as I said in the comment) or press CTRL+ALT+SPACEBAR to switch back to completion mode.
EDIT: I've found out that whenever you type Stri (String will show highlighted in the list now) and you press . (dot) it will autocomplete and stay at the same line.
I think your way of doing this in C# isn't possible in Visual Basic.
I had the same problem and discovered that Auto list members was not enabled on my machine. It's under Tools > Options > Text Editor > Basic > General. This gave me the intellisense I was looking for.
Simple thing which can be used when you face this kind of issue is to press
tab key instead of Enter key when the IntelliSense provided me prediction list.
Do this in VS 2010 with VB.NET:
On a blank line, type anything that isn't a variable, property, method, etc. I will use woo as an example.
Hit Enter or move the cursor up or down a line.
VS will add parenthesis to the end of it, turning it into woo().
Annoying, isn't it? Now insert foo in front of woo(), separated by a space like this: foo woo().
Move the cursor up or down (don't use Enter). VS turns it into foo(woo()), somehow drawing the conclusion that you want to pass woo() through foo(). What gave it that idea?
I know that the IDE isn't a text editor, but there are many times when I will want to paste in some text from a business requirements document or even some SQL and then comment it out after the fact. c# is great for this since it never assumes that I am trying to do anything, but the VB.NET IDE ends up parsing the holy love out of whatever block of text I paste into it and I end up having to edit out everything it added in.
Why does it do this? Can I tell it not to?
Unselect Pretty listing (reformatting) of code. You can find this under: Tools -> Options -> Text Editor -> Basic -> VB Specific
I'm using coderush with vs 2008. coding in VB.net.
I don't see any evidence of Intellassist, all i see is the usual VS intellisense.
Is this normal? Preferred? Do most people leave the defaults or do most/some turn off vs's intellisense?
Does intellassist somehow agument intellisence?
thanks

I see CodeRush Intellassist as an extension of Visual Studio Intellisense and not its replacement or anything else. Intellassist completes the text at the editor caret position with an in-scope identifier and may include other suggestions, such as physical file path completion or enumeration elements completion (which is not actual for Visual Basic).
To use Intellassist, just write code as you normally would. When Intellassist senses one or more suggestions matching the code you've entered so far, the best suggestion will be displayed to the right of the editor caret.
Once Intellassist is active, you have several options:
Press Enter to accept the highlighted suggestion. If you have the case-sensitive option turned off, Intellassist will ensure the entire suggestion is properly cased to match the declaration.
Press Shift+Enter to accept a portion of the suggestion. Shift+Enter accepts from the caret to the character preceding the next uppercase letter in the suggestion. For example, if "AllowMultipleSelections" was the suggestion, and "al" had been typed in, pressing Shift+Enter successive times would cause the selection to shift as follows:
Shift+Enter is useful when you need to create a new variable name that is similar to a portion of an existing suggestion, or when you want to quickly access a different but similarly-named suggestion (differing only in the latter portions of the text). You can press Shift+Enter to move the selection right, and then start typing to get other suggestions.
If more than one entry is suggested you can cycle forward and backward through the suggestions by pressing the Tab and Shift+Tab.
Press the Delete key to cancel the suggestion.
Do nothing for a few moments and Intellassist will hide the suggestion.
If the text you've entered is a code template that you want to expand, just press Space or ; to expand the template normally.
Continue typing (narrowing down the suggestion list or ultimately ignoring all suggestions).
Intellassist is highly configurable. You can specify whether case-insensitive suggestions should be made, and also change a host of other options.
In MS visual studio we just right click add watch.
How does one do this in Xcode?
Use the po command in the Debug area
Set up a breakpoint on the relevant area of code, then when the program stops at the breakpoint, enter commands in the Console in the Debug Area.
The relevant command is po (print object) followed by the expression you want to evaluate.
If the Debug window is not visible in XCode, you can show it via the top menu:
'View' -> 'Debug Area' -> 'Activate Console' (XCode v8.x)
Example
To evaluate an expression like var1/var2 where var1 and var2 are both doubles, enter the following in the Console:
po var1/var2
The Console will return something like:
(double) $2 = 3.085 [no Objective-C description available]
Showing object properties
You can also return a particular property of an object currently used in the code at that breakpoint:
po [bankInfo city]
And it will return something like:
(id) $4 = 0x000069e8 Testville
Note though that the Console doesn't seem to like the dot notation and prefers the square brackets when applicable. For example, this returns an error for me:
po bankInfo.city
I hope this is what you've been looking for.
Gabe's answer is almost there but missing one crucial detail: Select Debugger Output . By default the bottom option is set to Target Output, so the po command doesn't show you anything.
Here is a sandwich app from a tutorial I'm debugging:
Being an xcode newbie and coming from a MS Visual Studio Background, I wanted exactly what the OP was looking for. While playing around from reading Gabe's answer I selected Debugger Output and got what I wanted.
My seniors told to use NSLog(#variable)..........
Set some breakpoints in the begginning of the looping and functions. Once u click on the breakpoint(one similar to arrow) button in the editor window the "Build and debug tool" will get enabled. You can then go to the debugger by clicking the debugger icon. on the right of the debugger window variables will be visible select self->then the instance variable u r going to set watch point.Right click on that and select "watch variable".A trigger point will be set and you will be notified with the value of the variable when changed.
As fas as i understand you would like to see when a variable is changing. For this make a breakpoint and right click on it and choose Edit Breakpoint. A window will appear:
Make sure you choose the right action like Debugger Command or Log Message and check the tick down at the options Automatically continue after evaluating. So you get some kind of action (e.g. logging, sound, etc) and wont stop at the breakpoint.
If you want to know when the variable changes, use a "watch":
Set a breakpoint somewhere in the class in question;
Run the app in the debugger and let it stop at your breakpoint; and
Go to the "Variables" view in the left side of the bottom "Debug" panel and right click on the property in question and choose "Watch".
For example, here, I've stopped at a breakpoint in viewDidLoad, and added a "watch" for total:
(This is Swift, but the same is true for Objective-C, too.)
Now, if I "continue" execution (), Xcode will pause whenever this property changes and I can see at what line of code total is changing, the stack trace to get to that point, etc.
