• .NET Development waveInOpen creates a Time Critical thread

  Hi all, I'm trying to merge some legacy code with my net .NET2.0 GUI, using VS.NET 2005 beta 2, C++. It was going well until I linked my old audio input code. Upon calling waveInOpen, my legacy code now seems to hang my entire system. waveInOpen specifies a callback to use, as follows : void CALLBACK AudioInputCallback(HWAVEIN hwi, UINT uMsg,DWORD dwInstance, DWORD dwParam1,DWORD dwParam2) {    switch (uMsg)    {        case WIM_OPEN :       ...    } } Upon debugging, I found that this callback is being polled, but as soon as I take ...Show All

• SQL Server #N/A in measures - Excel 2003 client

  After giving some users read access to the cube, by using a readonly role - The [Measures] are displayed with #N/A in Excel 2003. Only users with loal administrator previledge can see measures. Please advise. What I encountered with AS 2005 was that Cell Security defaulted to denying access to a reader role, resulting in #N/A. So I simply entered "1" as the MDX expression for "allow reading of cube content" - not sure if this is the issue for you as well: http://msdn2.microsoft.com/en-us/library/ms174847(SQL.90).aspx >> Granting Custom Access to Cell Data ...Show All

• Visual Basic How do I execute an SQL Command with an ODBCConnection and MySQL database?

  I have tried many times in many different ways to get this to work.  When I try to compile the code below I get the error message on this line of code " Dim myCmd As New SqlCommand(mySQL, cn)" then I get the error message "Value of Type 'System.Data.ODBC.ODBCConnection' cannot be converted to 'System.Data.SQLClient.SQLConnection'.

• Visual C++ Passing an array of structs

  I have this struct struct student//Struct layout { char name[30]; char id[11]; float gpa; int age; char gender; }; this is the syntax I have for the function I want to send the array to: void firstmenu(student students[]); student students[5];//Struct Array, this is where I make the array firstmenu(students[]); and that is where I try to call it.
