hi, everyone... i have problem to fill second column in a tree control... the cells are editables, but the first column is edited and i get error on second columns index???!! my codes are as follow: int CVICALLBACK startCB (int panel, int control, int event, void *callbackData, int eventData1, int eventData2){ double xn[100]={0.0}, sine[200]; double x[200]={0.0}, y[200]={0.0}; double amp=1.0, cycle=0.25; int i,j,k=2; char sx[100], sy[100]; switch (event) { case EVENT_COMMIT:InsertTreeColumn (panelHandle, PANEL_TREE, 1, NULL); SetTreeColumnAttribute (panelHandle, PANEL_TREE, 0, ATTR_LABEL_TEXT, "X Value"); SetTreeColumnAttribute (panelHandle, PANEL_TREE, VAL_ALL_OBJECTS, ATTR_COLUMN_VISIBLE, 1); SetTreeColumnAttribute (panelHandle, PANEL_TREE, 1, ATTR_LABEL_TEXT, "Y Value"); SetTreeColumnAttribute (panelHandle, PANEL_TREE, VAL_ALL_OBJECTS, ATTR_COLUMN_VISIBLE, 1); for(i=0;i<100;++i) sine[i]=amp*sin(sqrt(2*PI*i*cycle/100)); i=2; xn[i-2]=0.0; xn[i-1]=amp*sin(sqrt(2*PI*cycle/100+xn[i-2])); while((xn[i-1]-xn[i-2]) >0.00001){ xn[i]=amp*sin(sqrt(xn[i-1])); sprintf(sx,"%.5f",xn[i-1]); sprintf(sy,"%.5f",xn[i]); ++i; SetTreeCellAttribute (panelHandle, PANEL_TREE, VAL_ALL_OBJECTS, 0, ATTR_CELL_TYPE, VAL_CELL_STRING); InsertTreeItem (panelHandle, PANEL_TREE, VAL_SIBLING, 0, VAL_LAST, sx, NULL, NULL, xn[i-1]); SetTreeCellAttribute (panelHandle, PANEL_TREE, VAL_ALL_OBJECTS, 1, ATTR_CELL_TYPE, VAL_CELL_STRING); InsertTreeItem (panelHandle, PANEL_TREE, VAL_SIBLING, 1, VAL_LAST, sy, NULL, NULL, xn[i]); } x[0]=0.02; x[1]=0.02; y[0]=0.02; y[1]=sine[2]; for(j=2;j<100;j+=2){ x[k]=y[j-1]; y[k]=y[j-1]; x[k+1]=y[j-1]; y[k+1]=amp*sin(sqrt(2*PI*y[j]*cycle)); k+=2; } PlotLine (panelHandle, PANEL_GRAPH, 0, 0, 1, 1, VAL_GREEN); PlotWaveform (panelHandle, PANEL_GRAPH, sine, 100, VAL_DOUBLE, 1.0, 0.0, 0.0, 0.01, VAL_THIN_LINE, VAL_EMPTY_SQUARE, VAL_SOLID, 1, VAL_RED); PlotXY (panelHandle, PANEL_GRAPH, x, y, i-1, VAL_DOUBLE, VAL_DOUBLE, VAL_THIN_LINE, VAL_EMPTY_SQUARE, VAL_DASH, 1, VAL_YELLOW); break; case EVENT_ZOOM: SetCtrlAttribute (panelHandle, PANEL_GRAPH, ATTR_ENABLE_ZOOM_AND_PAN, 1); SetCtrlAttribute (panelHandle, PANEL_GRAPH, ATTR_ZOOM_STYLE, VAL_ZOOM_TO_RECT); break; } return 0;} it doesnt like the 1, as second columns index in the following code: InsertTreeItem (panelHandle, PANEL_TREE, VAL_SIBLING, 1, VAL_LAST, sy, NULL, NULL, xn[i]); why i cannot find the reason... can anybody help me out? thanks snd kind regards

Here it is (I forgot to put the attachment yesterday)

I corrected the code that writes to the tree, but it seems to me that you haven't looked at the sample code I pointed you to before. Please read this discussion again and pay attention to this sentence: (...) InsertTreeItem creates an item in the tree, writing in column 0 and returning the item index. SetTreeCellAttribute can write to other columns of the same item by passing the item index and the column index to it. It dates 4 days back...
