Which code segment should you use? A. this.formborderstyle = System.Windows.Forms.FormBorderStyle.None; System.Drawing.Drawing2D.GraphicsPath path = new System.Drawing.Drawing2D.GraphicsPath(); path.addellipse(0, 0, this.width, this.height); Region reg = new Region(); this.region = reg; B. this.formborderstyle = System.Windows.Forms.FormBorderStyle.FixedSingle; System.Drawing.Drawing2D.GraphicsPath path = new System.Drawing.Drawing2D.GraphicsPath(); path.addellipse(0, 0, this.width, this.height); Region reg = new Region(path); this.region = reg; C. this.formborderstyle = System.Windows.Forms.FormBorderStyle.None; System.Drawing.Drawing2D.GraphicsPath path = new System.Drawing.Drawing2D.GraphicsPath(); path.addellipse(0, 0, this.width, this.height); Region reg = new Region(path); this.region = reg; D. this.formborderstyle = System.Windows.Forms.FormBorderStyle.FixedSingle; System.Drawing.Drawing2D.GraphicsPath path = new System.Drawing.Drawing2D.GraphicsPath(); path.addellipse(0, 0, this.width, this.height); Region reg = new Region(); this.region = reg; 2 / 14

6 03 bool canprint = CheckPrintAccessControl(); 04 if (!canprint) { You need to ensure that the following requirements are met: When the user has no print access, font and file stream initializations are not executed and the print operation is cancelled. Print operations are logged whether or not the user has print access. What should you do? A. Add the following code segment at line 05. pntdoc.beginprint -= new PrintEventHandler(PrintDoc_BeginPrint); pntdoc.beginprint += new PrintEventHandler((obj, args) => args.cancel = true); pntdoc.beginprint += new PrintEventHandler((obj1, args1) => LogPrintOperation()); B.

9 object sender, DataGridViewCellEventArgs e) { if (e.columnindex == 0)? { var cellvalue = datagridorders[ e.columnindex, e.rowindex].value; if (cellvalue == null string.isnullorempty(cellvalue.tostring())) { datagridorders.endedit(); B. private void datagridorders_validated( object sender, EventArgs e) { if (datagridorders.currentcell.columnindex == 0) { var cellvalue = datagridorders.text;?if (cellvalue == null?string.isnullorempty(cellvalue.tostring())) {?datagridorders.endedit(); C. private void datagridorders_validating( object sender, CancelEventArgs e) { if (datagridorders.currentcell.columnindex == 0) { var cellvalue = datagridorders.text;?if (cellvalue == null string.isnullorempty(cellvalue.tostring()))?{ e.cancel = true; 8 / 14

10 ? D. private void datagridorders_cellvalidating( object sender, DataGridViewCellValidatingEventArgs e) { if (e.columnindex == 0) { if (e.formattedvalue == null string.isnullorempty(e.formattedvalue.tostring()))?{ e.cancel = true;? Answer: D 7.You create a Windows application by using the.net Framework 3.5. The application is named APP1. APP1 has the following specifications: It merges information from text files. It reads each text file as a string. It runs on a server computer named Server1. Another application named APP2 also runs on Server1. You discover that when a function is used to merge the text files, APP1 consumes additional memory. This additional memory consumption affects the operations of APP2. You need to modify the design of APP1 to ensure minimum effect on APP2. What should you do? A. Use the + operator for the merge process. B. Use the StringBuilder.Append method for the merge process. C. Write a code segment to perform the merge process on a new thread. D. Write a code segment in a separate project to perform the merge process. Configure the project to start the merge operation as a new process. 9 / 14
