Calling A Tool From Another Form to Another?

Question

im working on a code-editor(winforms) and Im just wondering if its possible to call a specific box from a form to another?

sample for this set of codes:

int line = 1 + richTextBox1.GetLineFromCharIndex(richTextBox1.GetFirstCharIndexOfCurrentLine());
int column = 1 + richTextBox1.SelectionStart - richTextBox1.GetFirstCharIndexOfCurrentLine();
label1.Text = "line: " + line.ToString() + ", column: " + column.ToString();

***code above was inside a timer which calls the count of line and column in a richtextbox like in lower rightpart of actual code editor .

now im just wondering if its possible to call the label that displays to the main form and will display to another but will still run .

like in mainform theres the code for richtextbox and on other form it should have the code of label that connects to the mainform .

my question is it possible to call a tool function from another form to another?

hope you could help me, really in need and thanks a lot!

I'm 99% sure there is a duplicate question here, but the short answer would be to use an event model and subscribe to that event — lc., May 09 '13 at 02:32

As long as you have a reference to that form toolbox, just expose that Label/TextBox or whatever you want to change via a public property and set it from your context.

public class ToolBox : ToolBoxBase
{
   public CustomLabel
   {
      get
      {
         return label1.Text;
      }
      set
      {
         label1.Text = value;
      }
   }
}

private ToolBox toolbox;
void ShowToolBox()
{
   InitToolBox();
   toolbox.CustomLabel = "New label";
}

As I'm not even sure what technology the question refers to I added a poor pseudo example to get you the idea. The InitToolBox method initializes the toolbox and displays it, and sets the field toolbox with a reference to it.

If the other form runs on another thread, then you'll have to invoke the label setter asynchronously. See this question for more instructions.

And from what you seem to be describing there the easiest way to have a reference, as well as being a good logical construct for the two forms, is to have one form be the MDIParent of the other form. – Adrian May 09 '13 at 02:36
@Shimmy even two forms are not mdi's? – Elegiac May 09 '13 at 02:44
@Elegiac yes as long as you have a reference to it and it runs in the same thread. Please see my updated answer. – Shimmy Weitzhandler May 09 '13 at 02:48
@Shimmy ok sir ill try to do it and make some logic .w8 – Elegiac May 09 '13 at 02:49
@Elegiac really it's not complicated, just copy the code above to your tooltip class and you're done. Good luck! Please don't forget to vote / accept answer if this post helped. – Shimmy Weitzhandler May 09 '13 at 02:50
@Shimmy, sir the ToolBox was missing :/ how to add toolbox in my form? – Elegiac May 09 '13 at 02:52
Create a field in your form then set that field with the toolbox. – Shimmy Weitzhandler May 09 '13 at 02:55
lol i thought toolbox was a reference but i think its the container of all tools that your referring . sorry sir i dont have anydesigner in my form tools are called by codes only . but still +1 for the help . – Elegiac May 09 '13 at 03:00
Then you can have a field that holds a reference to the label :) – Shimmy Weitzhandler May 09 '13 at 03:02
@Shimmy sir im thinking if i can use the using namespace; method? sample for mainform namespace (name of otherform); then i can call all tools from main is that possible? – Elegiac May 09 '13 at 03:05
