The code below is what I'm having problems with... The combobox part is getting me angry and i've searched everywhere, code guru, msdn, stackoverflow, daniweb... And I cant figure it out. Its for a game my friend plays. I play and quit on and off.. I decided to do a calculator for him..

Problem: Cannot figure out how to determine which item the person clicked in the combobox... I will post a picture of the program in the attachments and the project folder.

//Snippet that Im having trouble with... + My attempt.

private: System::Void comboBox2_SelectedIndexChanged(System::Object^  sender, System::EventArgs^  e) {
		if (comboBox1.SelectedText == "Chaeldar (Lost City)")
        {
			 int TPOC = Convert::ToInt32((c1)+ '12');    
			 this->textBox2->Text = TPOC.ToString();
//Attempted to add 12 to the value from textbox1(inputted by the user) when this option from the combo box is selected and then put that answer in textbox2.

        }
        else if (comboBox2.SelectedText == "Duradel/Lapalok (Shilo Village)")
        {
          
// add 13 to textbox1 value if this option is selected from the combobox.
        }
}
//Full Program code. Problem at line 348..

You want something along these lines

int tb1value;
Int32::TryParse(textBox1->Text,tb1value); //enclose this in an if to make your own error handling
int tb2value = tb1value+comboBox1->SelectedIndex+12; 
//it doesn't matter what's in the box, just use the offset
textBox2->Text = tb2value.ToString();

Edited 5 Years Ago by jonsca: n/a

Wow thats exactly what I wanted... saw that on a youtube video but the part I did not understand is the (tb1value+comboBox1->SelectedIndex+12;)... The selected index part is the piece of that line i dont understand..

I wanted it so that if they select the first option in the box, add 12.. if the second option add 13 if third add whatever.. does that do it for me? what does that selected index do? I know its if they select and option but does this apply to a specific option or all options in the combobox?

Would I do.. if (comboBox1.SelectedIndex == "Chaeldar (Lost City)") add 12? or 13? or 19? or whatever? (I know how to add to it)

If you have the first option selected (option 0) it returns 0 (total +12), second option (option 1) it returns 1 (total +13). Chaeldar would add a total of 12. Just make a form with a combobox on it and play around with it a little. You don't need the if statement like you have it because the box is agnostic to the actual contents, as long as you keep everything in the right order it's fine.

but does this apply to a specific option or all options in the combobox?

Every option has an index associated with it.

I tried making a form with just a combobox.. I couldnt get it to work..

Every option I selected added +12 to the value... resulting in total of 11..

example: i entered 0, it added 12 to it.. resulted in 11.. Guess cuz the index is -1 :S
when I seletected first option, same thing, second option, same thing, third, same answer.

NVM Got it to work.. Now it adds 12 and stuff but when I select option 2, it adds 13, option 3 it adds 14... I wanted to choose what to add to each option... do you or anyone know how to do that?

Got it!! Thank bro your the best... just the little hints u gave.. Code incase anyone wants it:

private: System::Void comboBox2_SelectedIndexChanged(System::Object^  sender, System::EventArgs^  e) {
			 comboBox2->SelectedItem->ToString();
			 if(comboBox2->SelectedItem == "123"){
				int tb1;
				Int32::TryParse(textBox1->Text,tb1); //enclose this in an if to make your own error handling
				int tb2 = tb1+comboBox2->SelectedIndex+10; 
				//it doesn't matter what's in the box, just use the offset
				textBox2->Text = tb2.ToString();
			 }
			 else if(comboBox2->SelectedItem == "456"){
				 int tb3;
				 Int32::TryParse(textBox1->Text,tb3);
				 int tb4 = tb3+comboBox2->SelectedIndex+14;
				 textBox2->Text = tb4.ToString();
			 }

I think if nothing is selected the index is -1.

Oh, I thought that's what you wanted (to have the progression go by 1 each step). Ok. Well, make an array: cli::array<int> ^ pointsarr = {4,2,7,5,8,9,22}; and add pointsarray[comboBox1->SelectedItem] to your total instead.
