• Visual C++ BUG? auto_ptr assignment crash in VS2005

  I've just experienced a crash with VS2005 with the following: #include <memory> class Foo { public: Foo* MakeFoo() {return new Foo(*this); } }; void TestCrash() { Foo f; { // either of the next lines crashes std::auto_ptr<Foo> fooPtr1=NULL; std::auto_ptr<Foo> fooPtr2=f.MakeFoo(); } } This same sample doesn't compile on VS2003 as there is no assignment operator for auto_ptr. Changing these lines to use the constructor form: auto_ptr<Foo> fooPtr1(Null) fixes the problem. It seems that auto_ptr is using the wrong constructor -- it's implicitly casting to an auto_ptr_ref type. Is this a known issue What makes you believe that Did you ever look at the operator auto_ptr_ref() ...Show All

I've tried changing the order in the source code, but that doesn't seem to have any affect on the diagram.

• Visual C# how to give online updations for My own software?

  I have done one desktop application in visual c#, i want to give online updations for that software . i need full flow and coding for this. there are multiple ways of doing what you are asking but no doubt ciickonce would be the most appropriate way of updating your application. I have done previously (this was for .NET 1.1) a webservice which checks for updates on the server based on what my client application has sent in terms of details for itself, so when the webservice looks at the details sent from the client, it will then try to go through the files on the server to find an update for the client software, if there is one then it will send it down the wire to them, the client then accepts this and writes data to disk and no ...Show All

• Visual Basic Show and hide a form

  I have a form (frmResults) that shows a list of results for a name search. I would like to keep it open but hidden after the user selects a record to view, which opens another form (frmMain) and hides itself. The frmResults' Load event fills a table adapter based on parms passed to the form (first and last name). I have a button on frmMain that returns to frmResults using My.Forms.frmResults.Show and Me.Close. Problem: when I try to return to frmResults I get this unhandled exception: "Object reference not set to an instance of an object." It happens on the line where the table adapter is filled. Is there an easy fix for this or do I have to pass the name search criteria around to get the results to show again T ...Show All

• SQL Server Convert Milliseconds to HH:MM:SS

  I am writing a report that Queries a SQL DB using 'SQL Server Business Intelligence Development Studio'. I have a field in the DB called duration and it is in milliseconds. I am trying to find an easy way to convert the format from Milliseconds to HH:MM:SS. Nearest I can get is the following for the field: =Int(((Fields!DURATION.Value/1000) / 60) / 60) & ":" & Int(((((Fields!DURATION.Value/1000) / 60) / 60) - Int(((Fields!DURATION.Value/1000) / 60) / 60)) * 60) The output is in HH:MM. One issue with this is if the MM is say :03, it prints as :3. I lose the leading 0 so 9:03 (9hrs and 3 minutes) prints as 9:3. Where as 9:30 (9 hrs and 30 minutes) prints as 9:30 as it should. Is there an easier way to do thi ...Show All

• SQL Server Current Security Context Not Trusted When Using Linked Server From SAP

  Hello, I am experiencing a head-scratcher of a problem when trying to use a Linked Server connection to query a remote SQL Server database from our SAP R/3 system. We have had this working just fine for some time, but after migrating to new hardware and upgrading OS, DBMS, and R/3, now we are running into problems. The target database is a named instance on SQL Server 2000 SP3, Windows 2000 Server. The original source R/3 system was also on SQL Server 2000 (SP4), Windows 2000 Server. I had been using a Linked Server defined via SQL Enterprise Manager (actually defined when the source was on SQL Server 7), which called an alias defined with the Client Network Utility that pointed to the remote named instance. This alias and Linked Server wo ...Show All

• Audio and Video Development iHD Simulator doesn't display video post-Windows Media Format SDK Install

  After I installed the Windows Media Format SDK (9.5) for Windows Media Encoder 9, I noticed the iHD Simulator won't display video any more.

Any ideas Suggestion is to try the WMP 11 SDK: http://msdn.microsoft.com/windowsmedia/downloads/default.aspx Also, try using graphedit to play the video; that shares more code in common with iHDSim than WMP does. ...Show All

• SQL Server SQL comparison

  Hi there! can anyone help me out I need to compare a date from the database and the system date which will be coded in a store procedure in SQL... HELP!!!!! You may like to reconsider the answer given by Ali. DateTimes in NET are stored to a precision of 100 ns or 0.0000001 seconds whilst those stored by SQL Server in the SQL Server datatype DateTime are stored to the nearest 0.003333 seconds. Therefore you should not use a simple equality operator to compare them. Instead you should compare them based on the lowest precision argument, ie round the NET DateTime to the nearest 0.00333 seconds and then compare them. Regards, John Whattam. ...Show All
