Group: Forum Members Posts: 448, Visits: 12K	I have a FrmGetPayOff with TabControl1 on it. On page1 of tabcontrol1 I have several labels with names lbl1go, lbl2go, lbl3go, ... I would like to fill them with some numeric data found in an array ngopercents(). I have tried to follow some samples found in the forum but if I use the Ctype below it tells me I am missing an object and if I use the last several examples using an object the object in the line below ends up to be nothing and of course produces and error. What am I doing wrong in this code or how do I get the correct object? loObj = Me.TabControl1.TabPages(1).Controls("lbl" & i.ToString + "go") Dim i As Integer = 0 Dim j As Integer = 0 Dim loObj As Object For j = 0 To (nnumofplaces - 1) i = j + 1 ' CType(Me.Controls("lbl" & i.ToString + "go"), Label).Text = ngopercents(j).ToString + "%" ' CType(Me.Controls("txt" & i.ToString + "go"), Label).Text = ngoresults(j).ToString("C") ' loObj = Me.TabControl1.TabPages.Controls("lbl" & i.ToString + "go") ' loObj = Windows.Forms.TabControl.TabPageCollection.Controls("lbl" & i.ToString + "go") ' loObj = frmCalcPayOffs.TabControl1.TabPages(1).Controls("lbl" & i.ToString + "go") loObj = Me.TabControl1.TabPages(1).Controls("lbl" & i.ToString + "go") loObj.GetType().GetProperty("Text").SetValue(loObj, ngopercents(j), Nothing) Next TIA.
