You can do like this.. ON MDI Form public bool MenuItemControl { set { this.newToolStripMenuItem.Enabled = value; } } ON FORM CLOSED EVENT MDIParentForm MdiPF = (MDIParentForm)this.MdiParent;

private string msiplessey(string abc) { string value = ""; string values = ""; string adds = ""; string evenvalues = ""; string evenval = ""; string evenadds = ""; string resultadd = ""; string fval = ""; long add = 0; long abcd; long evenadd = 0; long result; int checkvalue = 0; int finalresult; for (int i = abc.Length - 1; i > -1; i -= 2) { value += abc.Substring(i, 1); } for (int j = value.Length - 1; j >= 0; j--) { values += value.Substring(j, 1); } abcd = (Convert.ToInt64(values) * 2); string oddvalue = abcd.ToString(); for (int k = 0; k < oddvalue.Length; k++) { adds = oddvalue.Substring(k, 1); add = add + Convert.ToInt64(adds); } for (int l = abc.Length - 2; l > -1; l -= 2) { evenvalues += abc.Substring(l, 1); } for (int m = evenvalues.Length - 1; m >= 0; m--) { evenval += evenvalues.Substring(m, 1); } for (int n = 0; n < evenval.Length; n++) { evenadds = evenval.Substring(n, 1); evenadd = evenadd + Convert.ToInt64(evenadds); } result = add + evenadd; resultadd = result.ToString(); finalresult = Convert.ToInt32(resultadd.Length); fval = resultadd.Substring(finalresult - 1); checkvalue = (10 - (Convert.ToInt32(fval))); if (checkvalue == 10) { checkvalue = 0; } else { checkvalue = (10 - (Convert.ToInt32(fval))); } return checkvalue.ToString(); }

Hi, I am Developing an windows application i want when ever my application runs then form opacity will increase slowly from 0 to 100% on timer tick. Thanks & Regards

The number to be encoded is 173946. Starting from the right side of the number (the units position), collect all of the odd position digits (i.e. digit 1, digit 3, digit 5, etc.) and create a new number leaving the digits in their left to right order. The new number would be 796.

Hello friends i am developing an application in which there is printing option... The printing option is working well but the problem is when the printdialog shows and by default the numbers of copies is 1 and if i increase the numbers of copies 2 or 3 then its only print one copy only why number of copies option is not working.... CODE int count = Application.OpenForms.Count; for (int i = 1; i < count; i++) { PrintDialog myPrintDialog = new PrintDialog(); memoryImage = new System.Drawing.Bitmap(panel1.Width, panel1.Height); panel1.DrawToBitmap(memoryImage, panel1.ClientRectangle); if (myPrintDialog.ShowDialog() == DialogResult.OK) { myPrintDialog.Document = printDocument1; printDocument1.PrintController = new StandardPrintController(); printDocument1.Print(); } printDocument1.Dispose(); }

I am developing an windows application in which i have to calculate check digit... For Example: Data to be encoded is "21435". encode: 2 1 4 3 5 Weighting: 5 4 3 2 1 ----------------------------------- Totals: 10 4 12 6 5 ----------------------------------- Then add them: 10 + 4 + 12 + 6 + 5 = 37 Next divide the total by 11 and get the remainder which is 37/11 = 3 remainder 4. The remainder is the check character. To type encoding the data 21435 that can be scanned, print (214354). How can i do this check digit calculation on every keypress event of textbox....... Help me in getting solution.....................
