Using commas in a text file and combow box

[Chris211]

I am trying to populate a combo box in VS2012 C++ Forms app. I am able to populate the box using the Streamreader. But the over all goal is I need the text file to work similar to a SQL database ie,

If I have a text file like this

1, 5
2, 6
3, 7
4, 8

I need to populate the combo box with the 1,2,3,4
then I need to be able to take the value (after the user has selected the combo box value) and do a Item search. So if the user selected 3, I will need to open the file and find 3, but return 7 as the value.

Any help would be nice here is the function that I am using right now to get the combo box to populate using just a normal text file like.

private: void FillCompanyBox(void){
		                 try
                 {
                     // Open File Using A Stream Reader Object
                     StreamReader ^streamReader = gcnew StreamReader("Company_Name.txt");
                     try
                     {
                         // Read Each Line Until End Of File
                         while (!streamReader->EndOfStream)
                         {
                             // Read Line (Trimming Whitespace)
                             String ^lineOfFile = streamReader->ReadLine()->Trim();

                             // Add It To Drop Down If It Is Not Empty
                             if (lineOfFile->Length > 0)
                             {
                                 U_Company_Name->Items->Add(lineOfFile);
                             }
                         } 
                     }
                     finally
                     {
                         // Delete Stream Reader If It Was Created
                         if (streamReader)
                         {
                             delete (IDisposable ^)streamReader;
                         }
                     }
                 }
                 catch (Exception ^e)
                 {
                     // Display Error
                     MessageBox::Show(e->ToString());
                 }
