Visual Studio - Space after auto filling word

recently moved over to visual studio
When I start typing a word, let's say "Tex" I get the popup with possible auto-fillings, and if I press enter, it automatically changes it to "TextBox"
The problem I have is, whenever I do that, I have to press 'space' to start typing the next word, something that get's pretty annoying if you type 10,000 words..
Is there an easy way to make the typing start one space after the autofilled word?
Thank you in advance :)

Yes, you can simply use the Spacebar to perform the auto-complete instead of pressing Enter. Both methods finish the completion of the word, but using the Spacebar will also add a space after the word.
It even works when using the "." character after a name; you still get the intellisense list of object members to choose from, and auto complete will magically remove the space(s) when you type a ; or closing brace }, or any other character that triggers line formatting.
Example
// This is what it looks like while typing, using Spacebar to complete the words
this .textBox1 .Text = "hello"
// And then as soon as the `;` is added, it's all fixed:
this.textBox1.Text = "hello";
And, for what it's worth, whitespace is allowed on either side of the . between an object and it's members. So even if the spaces were left as in the first example, the code still compiles and runs just fine.

RichTextBox replacing input with "random" unicode character

I have an application that allows users to browse through data. I have menu items controlling navigation and a RichTextBox displaying the data. Very straightforward.
tl;dr version
It mostly works except for one strange problem. There are instances where the RichTextControl will replace the first character typed with a random unicode character. Feel free to download this sample app and see for yourself:
http://www.technitivity.com/stackoverflow/RichTextFocusTest.zip
Full Explanation
The issue happens when navigating between rows. It's best described with a few use cases:
Use Case 1
Navigate anywhere into the dataset.
Press back.
Press next.
Type any letter, say, "F".
Result: "F" appears in the RichTextBox as expected.
Use Case 2
Navigate anywhere into the dataset.
Press back twice.
Press next twice.
Type the letter "F".
Result: instead of "F", "ᅲ" appears in the RichTextBox.
Use Case 3
Navigate anywhere into the dataset.
Press next twice.
Press back twice.
Type the letter "F".
Result: instead of "F", "᧴" appears in the RichTextBox.
The navigation process entails nothing more than:
// either forward
i++;
// or backward
i--;
// then update
RichTextBox1.Text = MyData[i];
Procedurally speaking:
// This works
RichTextBox1.Text = MyData[3];
// This works
RichTextBox1.Text = MyData[3];
RichTextBox1.Text = MyData[2];
RichTextBox1.Text = MyData[3];
// This doesn't work
RichTextBox1.Text = MyData[3];
RichTextBox1.Text = MyData[2];
RichTextBox1.Text = MyData[1];
RichTextBox1.Text = MyData[2];
RichTextBox1.Text = MyData[3];
Granted, that's not what's actually happening, but it is what's effectively happening.
It's important to note that this doesn't happen if the RichTextBox loses focus between updates. It only happens if the RichTextBox retains focus while its Text attribute is updated in accordance with the above description.
I'm at a complete loss about what's causing this, how to fix it, or why I can't seem to find anyone else with this problem.
I've reproduced it on 64-bit Windows 7 and 32-bit Windows Vista. This is on .NET Framework 4 though I was also able to reproduce on a .NET Framework 2 project.
Here's hoping someone else has run across this (and solved it!)
Edit:
Here's a screenshot:
http://www.technitivity.com/stackoverflow/RichTextBox-Screenshot1.png
As mentioned in the comments, to reproduce this in the sample app, you have to use the keyboard menu shortcuts. If you click on the menu items (or the toolbar buttons), the RichTextBox loses focus and the problem goes away. But if you navigate through the items using Alt+Left or Alt+Right (back/next) and then type, you should see something like what's shown in the above screenshot.

I hesitate to call this an "answer", but I couldn't find a "Post a Hack" button and this hack does get me by for now. I'm not thrilled about it, but sometimes you just have to move on. Here it is.
Since the problem went away when the RichTextBox lost focus, I tried an experiment:
I created a visible, 0-pixel wide textbox, called Hacktastic.
I added a KeyPress event to the RichTextBox.
On KeyPress:
Hacktastic.Focus();
Hacktastic.Text = KeyChar.ToString();
MyRichTextBox.Focus();
This worked and (at least for now) I'm sticking with this as a solution. If anyone could still try out my sample project and reproduce and/or solve this, I would love further feedback:
http://www.technitivity.com/stackoverflow/RichTextFocusTest.zip
Steps to repro in the test project:
Using Alt+Right arrow, move through the dataset to, say, the fourth record.
Using Alt+Left arrow, move back through the dataset two places, to the second record.
Using Alt+Right arrow, move back to the fourth record.
Press any KeyChar.
Observe KeyChar is replaced with a "random", large-value unicode character.
I say "random" because a specific set of navigation (back/next) keystrokes will insert the exact same unicode character. However, depending on where you start in the set or how far back you go, you'll get a different character.
Also, note that only going back one record and forward one record does not cause the problem. You have to move at least two records for this to happen.

Visual Studio: How to show Overloads in IntelliSense?

Once code has been written, the only way I know of to view the overloads for a method is to actually edit the method by deleting the Parenthesis () and reopening them.
Is there a shortcut key that I could press to activate this instead of having to edit my files?
For an example, please reference the ShowDialog Overload screen shot below:

With your cursor inside the parentheses, use the keyboard shortcut Ctrl-Shift-Space. If you changed the default, this corresponds to Edit.ParameterInfo.
Example:

Ctrl+Shift+Space shows the Edit.ParameterInfo for the selected method, and by selected method I mean the caret must be within the method parentheses.
Here is the Visual Studio 2010 Keybinding Poster.
And for those still using 2008.

Tested only on Visual Studio 2010.
Place your cursor within the (), press Ctrl+K, then P.
Now navigate by pressing the ↑ / ↓ arrow keys.

The default key binding for this is Ctrl+Shift+Space.
The underlying Visual Studio command is Edit.ParameterInfo.
If the standard keybinding doesn't work for you (possible in some profiles) then you can change it via the keyboard options page
Tools -> Options
Keyboard
Type in Edit.ParameterInfo
Change the shortcut key
Hit Assign

It happens that none of the above methods work. Key binding is proper, but tool tip simply doesn't show in any case, neither as completion help or on demand.
To fix it just go to Tools\Text Editor\C# (or all languages) and check the 'Parameter Information'. Now it should work

Great question; I had the same issue. Turns out that there is indeed a keyboard shortcut to bring up this list: Ctrl+Shift+Space (a variation of the basic IntelliSense shortcut of Ctrl+Space).

The command Edit.ParameterInfo (mapped to Ctrl+Shift+Space by default) will show the overload tooltip if it's invoked when the cursor is inside the parameter brackets of a method call.
The command Edit.QuickInfo (mapped to Ctrl+KCtrl+I by default) will show the tooltip that you'd see if you moused over the cursor location.

I know this is an old post, but for the newbies like myself who still hit this page this might be useful.
when you hover on a method you get a non clickable info-box whereas if you just write a comma in the method parenthesis the IntelliSense will offer you the beloved info-box with the clickable arrows.

Every once and a while the suggestions above stop working, if I restart Visual Studio they start working again though.

you mean's change overload.
just Press Shift + ↑ / ↓

Mine showed up in VS2010 after writing the first parenthesis..
so, prams.Add(
After doings something like that, the box with the up and down arrows appeared.

selenium c# nunit problem getting focus off a textbox

I am testing a web app where a file is to be renamed as follows
1)first click on the files name
2) this will make a textbox appear
3) I type the new name in textbox
4) I have to click outside the textbox so that the new name gets set.
or
4) Press enter key
The problem is in step 4. I've tried to get it to click at several places in my app, but the textbox doesn't loose focus and hence the name doesn't get set. I've even tried to use focus command, but, in vain.
Also tried to do this with enter key, but, seems that it doesn't work too. I tried keypress, keypressnative, etc. nothing seems to work.
Note: this sequence works when I do it manually and doesn't work when I do it from IDE or RC for C#.
Any help in this direction??
Thanks,
Vamyip

Selenium does not always fire the proper events. Probably your application relys on the blur event of the text box?
Try
selenium.fireEvent(locator_for_textbox, "blur");

Capybara throws an error because the driver does not support 'blur'
So I use:
find('html').click

Problem changing values in textbox

Simplifying
I have a text box and a button
The button just create an messagebox with the text from the textbox.
But i change the value of the textbox, the new value apears (Ex: Type 123) but the message box does not show the value.
If i try to use the value in the programming (get the value by textbox1.text) the variable has nothing ( textbox1.text = "") but i can still see what i typed in the form.
Anyone has any clue?

Your button's click event handler should look something like this
private void button_Click(object sender, EventArgs e)
{
MessageBox.Show(textBox.Text);
}
I suspect you already have code similar to this and that at some point the textbox is cleared or otherwise set to String.Emppty but without seeing actual code it is difficult to help you

When/where did you check the value of textBox1.Text? If you're checking it in the constructor, Form1_Load, or anything else that occurs before you'll have typed text, you will get an empty value.
To properly check the value of textBox1.Text, you should set what's called a breakpoint on the line that calls MessageBox.Show(textBox1.Text). To do this, click in the grey area of the source editor (it's on the far left) on the line containing MessageBox.Show(..). A red circle will appear and your code should be highlighted. When you run your application and click on your button, your application should pause and Visual Studio will highlight that line and from here you can hover over "textBox1.Text" in the MessageBox.Show() line and it should show you the current value.
If your application is as simple as a form, a textbox, and your button1_Clicked event handling code, this should work no problem. If it is not this simple, then you need to look for anything that sets the value of the textBox in your code and make sure it isn't passing any blank values by using breakpoints.
To solve this properly, though, we really need more information.

Thanks Eric and Crippledsmurf. As both of you said, its hard to help without the code.
The problem I found is that when calling the form, I send some objects by reference, so I can track them down and I found that when (don't ask me why it happens that way, I'm still working on it) the construtor is called he make an new component, so the component in the interface no longer represents the one pointed by the variable "textbox1" (Yes Crash893, I haven't mispelled the name).
I found that I was making some mess with the references, and probably that was causing the problem. I fixed the problem by changing the actions performed by references for delegates and events, but I couldn't track down the exactly source of the problem.
Thanks, again, everyone for the insights.
