c# - Create a status bar? -

i moving rows table 1 server another using c# script. please don't tell me use ssis components that. looping incoming dataset using loop , want see current iteration, ie loop index in gui box. can use messagebox.show("text"), need press ok/cancel allow code continue. so, thought of using status bar instead. tried an example got online

the line this.controls.add(mainstatusbar); in example (below) causes error -

csproj.scriptmain' not contain definition 'controls' , no extension method 'controls' accepting first argument of type '.csproj.scriptmain' found (are missing using directive or assembly reference?)

this happens despite adding reference - system.windows.forms.dll , doing save (ie ctrl+shift+s). script has import using system.windows.forms; already.

why getting error , how fix ?

code -

protected statusbar mainstatusbar = new statusbar(); protected statusbarpanel statuspanel = new statusbarpanel(); protected statusbarpanel datetimepanel = new statusbarpanel();  private void createstatusbar() {     // set first panel properties , add statusbar     statuspanel.borderstyle = statusbarpanelborderstyle.sunken;     statuspanel.text = "application started. no action yet.";     statuspanel.tooltiptext = "last activity";     statuspanel.autosize = statusbarpanelautosize.spring;     mainstatusbar.panels.add(statuspanel);      // set second panel properties , add statusbar     datetimepanel.borderstyle = statusbarpanelborderstyle.raised;     datetimepanel.tooltiptext = "datetime: " +      system.datetime.today.tostring();     datetimepanel.text = system.datetime.today.tolongdatestring();     datetimepanel.autosize = statusbarpanelautosize.contents;     mainstatusbar.panels.add(datetimepanel);      mainstatusbar.showpanels = true;     // add statusbar form controls     this.controls.add(mainstatusbar);  }  private void button1_click(object sender, eventargs e) {     statuspanel.text = "button clicked."; }  private void checkbox1_checkedchanged(object sender, eventargs e) {     statuspanel.text = "checkbox checked."; }  private void textbox1_textchanged(object sender, eventargs e) {     statuspanel.text = "textbox edited."; } 

the program doesn't know this supposed refer form in statement this.controls.add(mainstatusbar);

you have way percentage has suggested.

the proper way use :

for instance

public partial class someform : form     {         public someform()         {             initializecomponent();         }     }  partial class someform     {         private void initializecomponent()             {                 this.mainstatusbar = new statusbar();             }     }

when use "this" keyword?
