• Visual C++ Exception handling showing undefined behaviour. Help !!!

  Question #1 : The following code crashes in Visual C++ compiler. It fails in the expression _BLOCK_TYPE_IS_VALID(). It means that, it is deleting a bad pointer. When I give a copy constructor, it works fine but the control does not even go in the copy constructor. Why is it showing this behaviour Question #2 : If I throw a local primitive type like an int, the address of that variable matches in the catch block if I am catching by reference. But for objects, the address for the variable in the catch block changes. Why #include <iostream> using namespace std ; class Exception { char * m_pszError ; public : Exception ( const char * p ) { cout << "Exception::E ...Show All

• Visual Studio Is it possible to get the DTE2 com object when starting devenv.exe with parameters...?

  I am currently writing some Visual Studio automation and would like to use the experimental hive so that when one of our users fires off Visual Studio from within our code any changes we make through code to windows toolbars etc are not persisted in their main version of Visual Studio. I have experimented with windows configurations, restoring settings on close etc, but this is still to risky for my liking (if the program crashes Visual Studio will be pretty messed up next time it is loaded outside of our code!!). This works perfectly from the command line using the rootsuffx argument but my problem lies in the fact that I need to start devenv.exe from code and get hold of the DTE2 com object. At present we do this by getting the CLSID or ...Show All

• Visual Studio Tools for Office Populate pivot table with pre selected items.

  I have populate a pivot table using C#.net. I have used analysis cube as source of the pivot table. Now by pivottable.MDX property I got the mdx which indicates what items I have selected from the pivot table page fields. I saved the MDX and closed the excel. In my pivot table I have only page fields and one data field. Now I want to repopulate the same pivot table where only pre selected items are selected and others are unselected. I want to do this programmatically. I am using VSTO 2005. How can I do this I think your question could be better answered by the folks over in the Excel newsgroup. At this level you are working directly with the Excel PIA, and that is something that VSTO has little influenc ...Show All

• Visual C# Objects and implement IDisposable being used in static classes

  Hi I have an object which implements IDisposable. As a result of this, anywhere it's used I'm disposing of it. However, in a few instances it is declared as a member variable in a static class. Since static classes cannot implement interfaces I can't implement IDisposable on the static class and dispose of the object there. Also, static classes can't have finalizers so I can't dispose of the object in there. Is there a way to do safely dispose of the object in the static class Or, do I even need to worry about it since the static class will live for the lifetime of the AppDomain and disposable object will be destroyed when the static class is reclaimed anyway Thanks!

I meant to also include this link , since it has images and troubleshooting tips toward the end of the page. Note that the most common problem is that you entered the key incorrectly while entering the connection settings in the Visual C# IDE. Please try creating a new key and re-entering. Some characters are hard to tell apart, particularly I and 1, and especially on standard-definition TVs. If you enter the wrong code, the connection attempt will time-out.

• Visual C++ Compiler Warning C4727 in Release but not Debug - Whole Program Opt Problem

  I have a static library project that uses "create precompiled headers" which builds fine in Debug configuration but when building in Release configuration I get a number of the following warnings: warning C4727: PCH named c:\project\Release\foo.pch with same timestamp found in c:\project\Release\foo.obj and c:\project\Release\foo.obj. Using first PCH. This causes the link to fail. I do not have more than one file that creates a PCH, nor do I have duplicate PCH's in the directory. I was able to bypass this issue and compile in Release successfully by turning off "whole program optimization", which is really not an ideal solution. WPO is definitely something I want to take advantage of. I really don't want to follow the ...Show All

• SQL Server SQL stored procs

  can anyone help me out.... i need to compare a date that was retrieved from the database and the system date then it must be coded in the stored procs of the database.. help!!!! Hi, perhaps you may have a look on the Date function available in SQL Server. Time can be added through the function DATEADD, days can be e.g. added with DATEADD(dd,1,GETDATE()) --adds one days, you can also substract days from the days by using negative figures.
