You ll use the unary operator in the next section to define subtraction of vectors. public static Vector operator -(Vector vector) { return new Vector(-vector.X, -vector.Y); } Overload the binary + and operators The addition or subtraction of two vectors produces a third, new vector. Consider a statement such as vectorSum = vectorA + vectorB. You can see that you wouldn t expect vectorA or vectorB to be changed by adding them together. You need a third, new Vector instance to assign to vectorSum. 1. Add the following code to overload the + operator. 2. public static Vector operator +(Vector aVector, Vector bVector) { 3. return new Vector(aVector.X + bVector.X, aVector.Y + bVector. Y); } 4. Add the following code to overload the binary operator. Notice that you can define subtraction by using addition and the unary operator. By reusing the operators this way, the operators behave consistently. 5. 6. 7. } public static Vector operator -(Vector aVector, Vector bVector) { return aVector + (-bVector); open password protected pdf using c#: How To Set And Remove PDF Document Security In C# - C# Corner open password protected pdf using c# Create Password Protected ( Secured ) PDF using iTextSharp in ...

Overload the * operator for scalar multiplication The operators you ve defined so far have used only Vector operands. You can also define operators that take different types of operands by changing the parameters to the overload method. Add the following code to define the * operator. When you use the * operator, you ll use it in an expression such as 2 * vectorA. If you want to reverse the operators, as in vectorA * 2, you have to define a second operator overload for * with the parameters reversed so that the integer parameter is second. public static Vector operator *(int scalar, Vector vector) { return new Vector(scalar * vector.X, scalar * vector.Y); } Define the ToString and Parse methods Add the following code to define the ToString and Parse methods. These methods are similar to the ones you defined for the SortablePoint class in 9. public static Vector Parse(string vectorString) { try { how to generate password protected pdf files in c# How to open the password protected pdf using c# - Stack Overflow

The wca.exe tool created two files for you, each of which you ll rename and move to the workflow directory. (Renaming isn t required but makes for easier source code tracking, I think.) Type ren ITruckService.Invokes.cs ExternalEventActivities.cs at the command prompt, and press Enter to rename the file. This file contains the generated CallExternalEvent activities. 7. Because the file we just renamed is a workflow activity, we need to move it from the current directory into the TruckFlow directory for compilation and use. At the command prompt, type move ExternalEventActivities.cs ..\..\..\TruckFlow and press Enter. 6. Click the minus sign next to Abbas in Level 04 to collapse this branch of the hierarchy. The total sales amount for Abbas is 1,594,335.3767, which, as you saw in the previous step, is actually total sales for both Abbas and Tsoflias. Other than the fact that you saw one Abbas member in Level 04 and another Abbas member in Level 05, it was not obvious from the member names which member represented the aggregated totals from child members and which were the aggregated values for the parent member from the fact table. You can change the template that creates the new member name to make a distinction. 7. Open the Employee Dimension Designer, click the Dimension Structure tab if necessary, right-click the Employees attribute in the Attributes pane, and then click Properties. 8. In the Properties window, change the MembersWithDataCaption to * (data). The asterisk is a placeholder for the member name. 9. Deploy the project, and then click the Browser tab of the Cube Designer when deployment is complete. Click the Reconnect button, and then drill down to Level 05 of the Employee hierarchy. Your screen looks like this: 8. Now we ll do the same for the external event activities. Type ren ITruckService.Sinks.cs ExternalEventHandlers.cs at the command prompt, and press Enter to rename the file. This file contains the generated CallExternalEvent activities. 9. To move the file, at the command prompt, type move ExternalEventHandlers.cs ..\..\..\TruckFlow and press Enter. 10. The external data exchange activities are now created. As a final step, let s add them to the workflow project. Right-click the TruckFlow project in Solution Explorer, select Add, and then select Existing Item. When the Add Existing Item dialog box appears, select both external event activity source files from the list and click Add. The managers data members now are more easily distinguished from the other child members as well as their parent member. 10. Switch back to the Dimension Structure tab in the Employee Dimension Designer, rightclick the Employees attribute in the Attributes pane, and then click Properties. 11. In the Properties window, click NonLeafDataHidden in the MembersWithData property drop-down list to review the available values. tring } add password to pdf c# Password - Protected PDF File Using ASP.Net C - C# Corner
