• Visual C++ Documentation popup when hovering over a function or class?

  I know the function signature appears when hovering the mouse over a function, but is there a way to get comments/documentation to appear when the mouse is hovered over a function or object, like how eclipse does it There are a bunch of applications and addins out there, that may do something similar to this. I suggest you take it to your favorite search engine, since I really don't want to advertise for any addon in specific here at the forum. ...Show All

• Visual C++ find the datatype

  Hi, Is there a function available in VC++ to check if the datatype of an object is string or not. Thanks in anticipation. Warm regards, Hi, U can use typeid operator. This operator returns const type_info& structure. U can use name() method of type_info structure for getting the name of type at run-time. For Example; int a; printf("%s",typeid(a).name()); //This will print int at run-time. In case of run-time polymorphism, We are using base class pointer to instantiate derived class methods. For Example; Base* a = new Derived(); printf("%s", typeid(a)); //this will print Baspr); //this will print Base* printf("%s", typeid(*a)); //this will print Baspr); // ...Show All

• Visual Studio Assemply info task must be installed for all developers?

  Must the assembly info task be installed for all developers (As the < Import Project = " $(APPDATA)\Microsoft\MSBuild\AssemblyInfoTask\Microsoft.VersionNumber.Targets " /> is added to the project file) Also when I start the app from debug configuration from Visual Studio it modify the assembly info file. Can I only make this happen when I start from Team Build Or will this only happen the first time (I have not run team build yet). I was thinking about modifing my proj file as described in Guatam Geoenka's blog to get the assembly info task to work with team build. What I have done is check in the AssemblyInfoTask as a solution folder and include the files. Then just add this ...Show All

• Visual C# Unable to debug C# solutions

  I'm using Visual Studio 2005 Pro. This problem is repeatable with archived code on backup discs as well as new solutions.

• Visual Studio VS2005 and VSS6: VS needlessly prompts to check-out solution

  Using VS2005 Team Edition for Software Developers and Visual SourceSafe 6.0d (build 9848) I have observed that VS2005 is prompting members of my development team to check-out our solution files from sourcesafe for no apparent reason. My team has several solutions and projects that are organized within SourceSafe thus: $\project1\project1.sln \project1.vcproj $\project2\project2.vcproj $\project3\project3.vcproj The project1.sln includes $\project1\project1.vcproj, $\project2\project2.vcproj, $\project3\project3.vcproj, the latter two being dependents of project1. Every time one of us opens project1.sln, Visual Studio prompts the user to check-out project1.sln. The comments in the check-out dialog say: & ...Show All

• Windows Forms I want to Restrictthe user to past the text in the textbox not write in the textbox

  I want to Restrict the user to past the text in the textbox not write in the textbox is it possible Thanks I think you posted in the wrong forum. Anyway... There are several way's to do this. It depends on how you will allow the user to past data. 1) You can disable all user input and control the pasting yourself by using the Clipboard class in the System.Windows namespace. 2) you can catch the KeyDown event of the textbox and filter out all the key or key combinations you don't want. And so allow only the right mouse button to paste (or any key combination you allowed) ...Show All

• Windows Forms NET 2.0 adds a new Form.Show (IWin32Window) method that is breaking my GUI test code.

  NET 2.0 adds a new Form.Show (IWin32Window) method that is breaking my GUI test code.

• Visual C# Inheritance, static variables

  Let's say that I am creating a program to make catalogue pages. I derived Class LeftCataloguePage and RightCataloguePage from the base class CataloguePage. As I am using many instances of each class with many member variables for catalogue dimensions, number of cells, margin spacing, etc, it would take a lot of time to call all the member functions of each class to change the dimensions so I decided to define static variables in the base class so that the inherited classes will have their own static variables and I will be able to specify static dimensions for LeftCataloguePage and RightCataloguePage seperately, and this will change all the dimensions for all instances of the classes. The problem is that the static variables in each derive ...Show All

No, the attribute must be applied to each method. ...Show All
