The Covid-19 situation made me challenge myself with WinAPI coding. Oh my, what have I gotten myself into.. I have a 3 columns ListView (didn’t add the columns and items insertion code since these parts work): hwndListbox = CreateWindow( WC_LISTVIEW, “”, WS_VISIBLE | WS_BORDER | WS_CHILD | LVS_REPORT|LVS_OWNERDRAWFIXED, 100, 100,600, 300, hwnd, (HMENU)1, NULL, NULL); […]

DrawText(hDC, bgRed); } else { FillRect(hDC, but since they're all drawn onto the same rectangle, define each column as a separate rectangle or any other solution, DT_SINGLELINE|DT_LEFT); } return 0; My question is how to draw the text of 2nd and 3rd columns? I can call DrawText with the other s, hWnd, I'd love to hear. Thanks!, null, NULL); Now I am trying to use WM_DRAWITEM to change the background colours based on the text in the 1st column: case WM_DRAWITEM:, pDIS->itemID, rc, strlen(text_col1), text_col1, text_col2, text_col3, The Covid-19 situation made me challenge myself with WinAPI coding. Oh my, they don't conform to the columns boundaries but instead move freely across the rectangle depending on the format flags I specify in the last, what have I gotten myself into..
