Hi all!!!

i'm quite bored with a problem I can't solve.
I'm doing a program which imitates the mouse, and I need that when I do "click" (double click or whatever) in another application, although the latter is actived now, I want my window to still keep the keyboard input to can handle it.

I have try with SetFocus() and GetFocus() from Windows API but I can't make it works.
If you could help me,it would be great;)

Thanks,

ciao!

Thanks Mazdak...

I was just working with hooks now, and I succeded getting all the keyboard input. But then I have a new problem which seems easier but I cannot solve.

In a form with some controls (all of them buttons) how can I know wich button is selected? I'm trying with the focused and containsfocus property but it's not working.

And the last thing... in case I could know which control is selected, how could I generate the click event of this button without actually "click" it?..

Thanks;)

Not sure but you can look through:

GetFocus() or GetGUIThreadInfo() API

Look for SendMessage() API. I remember that there are some samples in CP. Use search textbox at the top of the page.

On a textbox? What kind of textbox are we asking about -- WinForms, webforms, html, etc?

Sure. Using System.Runtime.Serialization(.Formatters.Binary):

Example:

            string[] a = new string[3]{"One", "Two", "Three"};<br />
<br />
            BinaryFormatter formatter = new BinaryFormatter();<br />
            MemoryStream stream = new MemoryStream();<br />
            formatter.Serialize(stream, a);<br />
<br />
            stream.Position = 0;<br />
            string[] b = (string[])formatter.Deserialize(stream);

Hope this helps,

As an addendum to turbochimp's example, please reference my response[^] to your post in the ASP.NET forum. In the future, please don't cross-post to multiple forums. At least give people a couple of days to answer the first post before reposting to another forum.

Hope that helps. Smile | :)

Hey

I am using a TreeView
I have made my own TreeNode that is made fron refular TreeNode(it saves obj to)
I have added this own made TreeNodes to my TreeView and this looks good.

But when i want to change anything in the tree i update the entire tree, this mens that al catalogs is colapsed?

I have tryed to store
Treenode tmp = TreeView.SelectedNode;
Do the changes
TreeView.SelectedNode = tmp;
TreeView.SelectedNote.EnsureVisibility

But when it is running TreeView.SelectedNote.EnsureVisibility i get an error about teh instans is null? but its not?

Is there any way to open up so the last selected is visible? or cant i make my own TreeNode class like this?

Hey!

I have solwe one bit of the problem.

When i select an item in thre tree and this item is an new item, then is vill change to old item with old imageIndex(icon).

I am doing this by :

tmpNode.SelectedImageIndex = 2;

where 2 is the index for old image, and this works fine until i select anotner treenode in the tree, then the icon is going back to be new again?

I have stated in my own made TreeNode that it is Visited TRUE, and this means that it is old.

The change to old icon is appering when i release the mouse button on another Treenode.

Any ide why it is doing this?

I would look at buying in a licensing solution from a third party - these people should be specialists in that area and will be much better at it than you are. Licence management in notoriously difficult and even the "experts" don't really get it right.

Calling a procedure on a loaded form

Hi,

From one form I would like to call a procedure on another form without creating a new loaded instance of that form.

The Scenario is that I have an MDI form loaded with a child form and when an action is evaluated on the child form I would like to call a procedure in my currently loaded MDI form to perform an action.

Any help is appreciated.

Regards

Stephen

Insert the following inside the evaluation method of your child form:

((YourMdiForm) this.MdiParent).WantedMethod(...);

The Form class has a property called MdiParent[^] which you can use to access the parent MDI form.

Does this help?

System.String - Reference Type

in .net documentation, System.String stated as reference type. so, i supposed it will pass the reference to the method and the modification will affect to the original variable. but, i found it is not true! here is the sample i draft.
anyone could give me a help so that i work as call by reference.?

<br />
		private void button1_Click(object sender, System.EventArgs e)<br />
		{<br />
			System.String A; System.String B;<br />
			A = "A for apple";<br />
			B = "B for boy";<br />
			Sub(A, B);<br />
            MessageBox.Show("A: "+A+", B: "+B);<br />
<br />
		}<br />
		private void Sub(System.String a, System.String b)<br />
		{<br />
			System.String tmp;<br />
			tmp = a;<br />
			a = b;<br />
			b = tmp;<br />
		}

Hi,
You need to use 'ref' keyword in the function declaration and while passing the value.
ie private void Sub(ref System.String a, ref System.String b){}
and Sub(ref A, ref B);

Thanks,
Sujith

If you pass an object of a reference type to a method, all modifications to the method parameter object will affect the original object. For example changing the Text property of a TextBox.
That doesn't include changing the reference itself (this is what you do). If you want this to affect your original object you have to use either the out or ref method parameter keyword.
