• 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

• .NET Development facing the same prob

  I'm currently working on a application in VB.NET 2003, with a SQL Server backend. I was asked to make an import function that would allow a user to import an Excel worksheet into SQL Server. I'm aware you can do it from Excel directly to SQL Server, but the clients would like something that wouldn't involve the users of this application touching the SQL Server. I'm using an OLEDB for the Excel connection, and a ODBC connection for the SQL Server connection. Next, I have a button event that would open up a OpenFileDialog window, and a user can choose an Excel sheet. If the Excel sheet is valid, it would go on extracting the data into a dataset: ds = New DataSet ds.Clear() strSQL = "Select HEAT, Practice, C, Mn, P, S, Si, Cu, ...Show All

• SQL Server Printing at the bottom of report

  I need to print a subreport at the bottom of the last page of the report and I can't find a way to do it. Can't use page footer for it because subreports are not allowed in the page footer. Help please!!! I have the same problem. In Crystal I am able to print at bottom of the page. Does Microsoft or anyone have any idea if this feature will be added Print at Bottom of Page (Crytsal Reports) This check box causes each group value to print only at the bottom of a page. (Details continue to print in their normal positions.) The command is useful for printing invoices and other reports where you want a single group (for example, line items grouped by order number) to appear on a page and the value for that group (subtotal, summary fi ...Show All

• Visual Studio Class Diagram - How to use Associations & Properties correctly

  Hi, I realize I am a Class Diagram newbie, so i am hoping someone can help me with what is probably a simple problem. I have a very simple VB project with one form and one class. The class contains a few properties and methods that I want to use in the form. In the Class Diagram, I create an association between the two item by drawing an association line from the form (Form1) to the class (clsMain). This creates the following code in the form's declaration's section: Public Property clsMain() As clsMain Get End Get Set ( ByVal value As clsMain) End Set End Property I can then call the properties and methods in the class like so: clsMain.CurrentValue = CInt ( Me .txtInput.Text) ...Show All

• Software Development for Windows Vista While burning DVD: time estimate way off

  Using the event sink Update's IDiscFormat2DataEventArgs (2nd parameter) to retrieve: get_ElapsedTime and get_TotalTime (in seconds) The progression is as follows (below.) Notice that the total time estimate is really off, and after the time the elapsed time reaches it, they both progress together all the way to the end. This means, that in this case (burning a dvd) the total time actually ends up taking 7x the original estimate of 101 seconds. So 86% of the time, we end up reading as 100% progress. That original estimate of total time keeps being updated the same way until elapsed time hits it, then they both increase until the end. Not very useful for a customer... Am I missing something, or is there some way this can be improved 0, 0 0, ...Show All

• Windows Forms Datagridview unbound computed on bound...which event to use?

  Okay, I've spent the day trying to get this right, and not quite there yet. So much for rapid application development. Please advise My datagridview control has bound columns and unbound columns. I want the unbound columns values set based on a computation against the bound columns. Say my boundcolumn value is a date Sep 20 2006, so I want my unboundcolumn value to be assigned "Wednesday". I can do that fine in various events, but not immediately after the initial databinding...my unboundcolumns are remaining blank until my user starts selecting cells because I haven't solved which event when the datagridview is first loaded to use to calculate the unboundcolumns. Any ideas I've tried after the rowsadded and databindco ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. manual deploy

  Hello, Is there a way to manually deploy a game to the xbox via commandline I am wondering how I can deploy an application built on top of the XNA framework say, from the command line. It seems like XNATrans.exe might be responsible for the actual deploy, but I can't find any information on doing this. I am curious how to deploy an app not built in the Game Studio Express, but rather built with XNA Build. Hi, Unfortunately, this is the only way to deploy and communicate with your Xbox at this time. I suppose that you can try to automate VS as a workaround. V ...Show All
