• Visual C++ a lock system problem

  Hi, I'm working on a program using a .ocx control purchased recently (whose function is calendar and calculator). However, whenever I lock the system by pressing Ctrl+Alt+Del or the screen saver with password is about to run, my program crashes. I know it's due to that control, so I asked the company for the source code. But it is too complicated to make myself clear on those codes in a short time. If sb. has the experiences of dealing with such problem, pls do me a favour,just show me where should be focused on. Thank you very mcuh. If you have the source code create a debug build. Launch the sample program that causes the crash. ...Show All

• Windows Forms Rotating but not rotating text

  In a school project to design a custom meter control, I wanted to come up with something resembling a speedometer. I rotated the tic marks, and needle around the center of the control. I also rotated the text around the center point, but this wasn't exactly what I was looking for. How would I get the text to stay 'upright' while rotating it's ...Show All

• Visual Studio Tools for Office Proxy Remote Object?

  Dears, I have a class file containing the following code: Excel.Worksheet wsActive = (Excel.Worksheet)Globals.ThisWorkbook.ActiveSheet; ((Excel.Range)wsActive.Cells[1, 1]).Value2 = "Test"; I can retrieve the ActiveSheet object successfully (because I can get the ActiveCell location from the ActiveSheet object), however, I can't assign a value to the worksheet.

• Visual C++ Can anyone explain why this code line right or wrong?

  Can anyone explain why this code line right or wrong in C++ char c [0]; In standard C++, declaring arrays with zero elements is illegal: int n[0]; //illegal However, certain compilers do support arrays of zero size as non-standard extension. In contrast, dynamic allocation of zero sized arrays is valid C++: int n = new int[0]; The standard requires that in this case, new allocate an array with no elements. The pointer returned by new is non-null and it is distinct from a pointer to any other object. Similarly, deleting such a pointer is a legal operation. While zero-sized dynamic ...Show All

• Visual C# Deleting a file

  Hi, I'm trying to delete a file and the following File.Delete( "C:\\mytext.txt" ); causes an error saying "The name 'file' does not exist in the current context" How can I fix this error Thanks, Bruce   Is this a compilation error or a runtime error If it literally says 'file' and this is a compilation error then you have not properly capitalized the name of the class.  You have entered file.Delete("c:\\mytext.txt"); Change it to File.Delete("c:\\mytext.txt"); C# is case sensitive.

• Visual Basic VB2005 and MS Access

  Just a simple question here. I am curious if its best to use SQL for databases or can I use Access (.mdb files) databases I'm very new to 2005 btw. And porting from vb6. Thanks in advance. Hi It really depends on the complexity and number of users that will be using your program concurrently. If you have a large user base then Access is definitely not the way to go whereas if you only have one or two users and want an easy way of deploying the database with the application then Access would suit nicely. SQL Server on the other hand will handle a large number of concurrent users and will allow for scalability at a later time. ...Show All
