• Visual Basic Receiving strings from Serial Port

  Dear reader, I want to read a string from a serial port. I found the sample code in Help, to do this, with the following code: Using com1 as IO.Ports.SerialPort = My.Computer.Ports.OpenSerialPort("COM1") do Dim Incoming as String = com1.Readline() If Incoming is NOthing then exit do Else returnStr &+ Incoming & vbCrLf end if loop end using The problem is that if the return string does not end with LineFeed, the com1.ReadLine command does not return to the application, and as a result doesn not return any value to Incoming, to check it contents. The application give the impression that it is just hanging, untill I stop the application. Also how does the Read ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Rotating points in 3D

  I am working with some vector graphics that consists only of an ordered set of 2D points in XY space. The order of points determines the path that a line is drawn through them. I would like to be able to rotate the points in 3D so that I can flip and rotate the vector picture. After performing a rotate of some degree I want to be able to write the new set of points to an array or file or whatever. I also want to be able to display my vector image in a Window. So I have two questions: 1) Is there anything in DirectX that will help me rotate some XY points in a 3D space and then give me the resulting XY coordinates 2) What do I use to draw these points to the Window using DirectX In the past I have used normal Windows drawing me ...Show All

• Visual Studio F5 does not work ! : Need to use "Start new instance"

  Hello, I am trying to debug an application with my Visual Express 2005 c++. It compiles nicely a "hello world". However, to debug, if i use F5, it doesn't do anything.. I have to right click on the project and use the debug->start new instance or debug->step into new instance. And sometimes the debugger becomes unstable. I "think" that when the debugger starts, it goes to __tmainCRTStartup and hence I need to force the debugger to jump to my "main" .. Is this normal I would like my debugger starts in my main. Can anybody help me please thank you Hello, Yes, initial pressing of F5 (and also starting with "start debugging in the menu) makes the debugger fail completely ...Show All

• SQL Server Cumulative aggregation over time

  I want to do cumulative aggregation similar to "period to date", but not to a specific period in the past, but to the earliest record in the fact table. The problem is that I have 20 million accounts that I want to follow up on a daily basis, but they change rarely. After a year, perhaps half a million have changed. What I have done is to create a fact table that stores the balance when the account is opened, then only keeps track of the changes, so that when anyone deposits money a row is added with the increment. After a year that would give me about 20.5 million rows in the table. As an analyst I would like to enter a specific date, say 2005-08-20 and see the balance of all the accounts at that time. To do so, I simply need to ...Show All

• Visual Studio Express Editions Problem with Pasting to a DataGridview

  I try to C&P numbers ( from 1 to 9) from a Textbox (A1 in this case) to a DataGridview. However, the number refuses to appear in the DataGrid. The proper cell in the Datagridview gets selected (I get a blinking cursor) and the copying goes fine as well (I can paste with the mouse) I tried this method to C&P from The A1 Textbox to another Texbox and that went fine. The code in green below are other methods I've tried and that failed to deliver. My conclusion is, that I do something wrong with the last line, especially Me .DataGridView3.Text I have trawled all kinds of forums and databases for days now, but I'm stuck.

• SQL Server open cube to browse takes very long time

  I broke up my cube into 24 partitions. There are about 630M total fact rows in that cube. When I open the cube to browse in BIDS or SQL Management Studio it takes very long time to open (I think 30 minutes).

• Visual C++ TCHAR[]... How to manipulate it?

  Hi, I have a variable declared as TCHAR szFileName[260]; This variable contains a filename which is correctly printed out using the _tprintf() function. How can I check whether the string contains "iexplore.exe" I've been searching through google and trying to convert it to CString without any success. Pls help. You need to cast the csStr to LPCTSTR, otherwise it will print the pointer to the string instead of the string intself: std::cout << (LPCTSTR)csStr << std::endl; Also, if you are using cin/cout maybe it's better to use the STL string class rather than the CString class. CString is mostly for MFC/ATL projects rather than simple console apps. ...Show All
