Ctrl+Click to follow definitions

After taking a break from Microsoft IDE's and working in Java land, I'm missing the Control-LeftClick to click through a definition to navigate to the definition.

In Visual C# 2005 this just feels too clunky requiring a right-click and selection of a menu item.

I don't suppose anyone knows an option/plug-in that performs this?

Regards,
Ray

In my VS 2003 it's currently mapped to F12. But you can define an alternative key combination in Tools->Options->Keyboard and then slect Edit.GoToDefinition and type in a desired key combination. In VS 2005 it will be similar.

That is also mapped to F12. You could change the mapping if you prefer.

You cannot make selected row/cell inviible.
Use...

dataGridView1.CurrentCell = null;

Try this.

CurrencyManager cm = CurrencyManager)BindingContext[this.DataGridView1.DataSource];

cm.SuspendBinding();
this.DataGridView1.Rows[index].Visible = false;
cm.ResumeBinding();

Settings are stored in the config file as properties -Xml elements-. You can access them using the following line

global::ProjectName.Properties.Settings.Default

The class Settings is inherited from global::System.Configuration.ApplicationSettingsBase. Check it in your MSDN or more simply explore it using intellisense.

And?? Use the save method in your settings class.

global::ProjectName.Properties.Settings.Default.Properties.Add(new SettingsProperty("MyProperty"));
global::ProjectName.Properties.Settings.Default.Save();

Hello!

I have a question about the kind of propertygrid that is used in for example http://www.codeproject.com/cs/miscctrl/bending_property.asp[^]

For one of the properties I would want the user to only be able to chose out of the values 512, 1024, 2048, 4096 so that when he clicks this property a list with these values comes up.

I have been able to do this with strings using enums but not with numbers.

Does anyone have an idea how to solve this easily?

Best regards,
Hampus

Could it be possible?

Hi guys,

I'm having following situation:

private function DoSomething(){<br />
int x = 6257;<br />
<br />
CheckSomething();<br />
 Myclass.UseX(ref x, somethernr1);<br />
 Myclass.UseX(ref x, somethernr2);<br />
 Myclass.UseX(ref x, somethernr3);<br />
 Myclass.UseX(ref x, somethernr4);<br />
 ...<br />
 Myclass.UseX(ref 6257, somethernrN);<br />
}<br />
<br />
Checksomething(){<br />
 int x = 7834;<br />
 Myclass.UseX(ref x, somethernr1);<br />
 ...<br />
 Myclass.UseX(ref x, somethernrM);<br />
}

Is it possible that after CheckSomething() the x value in DoSomething() has changed?
(PS: There is something that sometimes locks up the application, we can't reproduce it and we're trying to figure out where it is (via logfiles, can't debug).)

Thanks.

My thoughts exactly, but I'm trying all possibilities here Smile | :)

.

And what if x was also (3d function) set in another thread? (timer).

Both x variables are local to their method, so they are unique for each specific method call regardless of which thread is doing the call. Local variables are allocated on the stack, and each thread have it's own stack. Local variables are only accessible by name inside their own method, outside the method they are never accessible by name, only if the method exposes a reference to the variable.

yep, in theory it is, anyway I changed the variable just to be sure, but to tell the truth, it's probably not that. We just don't know what's going wrong... Hope we can find it with some extra logging.

tnx.
