• Visual Studio 2008 (Pre-release) How can I get perfect performance when I draw 1000 lines?

  I'm creating an app that draws 1001 buttons, 1 center button and 1000 normal buttons, and 1000 lines, that each line connect the center button and one normal button.When I move the center button, the 1000 lines are refreshed.Now, I use a GeometryDrawing, but I get bad performance. How can I get better performance You should check out StreamGeometry class. MSDN documentation says: StreamGeometry is light-weight alternative to PathGeometry for creating geometric shapes: it does not support databinding, animation, or modification. Use a StreamGeometry when you need to describe a complex geometry but do not want the overhead of supporting databinding, animation, or modification. For example, because of its efficiency, the Stre ...Show All

• SQL Server SQL 2005 Express and Visual Studio 2003 - Connecting

  I have Visual Studio 2003 and had used it successfully with MSDE. I recently upgraded to SQL 2005 Express and cannot seem to connect to the SQL server. it appears in the list of servers on localhost, but when I try to create a new database it tells me that it "cannot create databases on this server." It will not even open up any existing databases. I have .NET 2.0 installed. I uninstalled SQL and reinstalled it, but nothing seems to help. I feel I must be missing something, but do not know what. I no longer have the MSDE installation files, so I hope I can get Studio to talk to SQL Express. Any help is appreciated. Looks like VS 2003 confused about the version of SQL Server installed ...Show All

• Visual C++ Win 32 Wrapper Class

  I was looking around for a while on different forums and sites and couldn't find any help to my problem. I'm trying to make a windows wrapper class. I'm using VS 2005 and doing it in visual C++. I'm declaring my handle as a private variable inside the class. private : hWnd; Then in my functions I have HRESULT cWindows::WinCreate() { hWnd = CreateWindow( "wndName" , "" , WS_OVERLAPPED, 0, 0, 600, 480, NULL, NULL, hInst, NULL); if (!hWnd) {return E_FAIL;} return S_OK; } hInst is a variable that I keep stored in the privates of my class and pass it in through the constructor. The WNDCLASS is registering itself fine, but whenever I try to create the window, I keep getting a a NULL ...Show All

• Visual Studio Team System Excel datasource problem - number format

  I have a web test that binds some Post Parameters to an Excel spreadsheet. I notice that some of the values read from the spreadsheet are set to "" (empty string) even though they have a value in the spreadsheet. Debugging the web test and looking at the spreadsheet it appears that the cells that are being read as "" are those with leading zeros. For example, here are 2 rows from my spreadsheet, the first row, second column will be read as "" (empty string) even though it has a value ( 0692189409). All other cells are read correctly. 106500804887 0692189409 81005 106500062973 5520163826 49255 It appears that the formatting of the cells is having some effect ...Show All

• SQL Server Can't I dynamically read from any file? - Connection Manager does not exist

  I have a Parent package and a child package. I have hard coded the value for the User::FilePath variable in the parent package. I am mapping this variable to the value of the same variable in the Child Package. I created a directory and sql file: "C:\temp\sqlb.sql". I have verified that the path variable value is passed to the child package by using a Script task with a messgbox call. How do I define an execute sql task to execute sql file: @[User::FilePath] & "sqlb.sql". I'm using this expression for the SqlStatementSource property. I have entered the OLEDB server information and specified the SQLSourceType = fileconnection. However I get the error: [Execute SQL Task] Error: Connection manager &qu ...Show All

• Windows Forms Accesing selected text in other application

  I'm running a Tray Application which gets on focus when a hotKey is pressed. In a few words, the user will select a piece of text in any application (IE, word, acrobat, or any custom application), press the hotkey registered by my application, and the application should be able to read and display the selected text. Could anybody guide me to accomplish this Is it possible Thanks, Seb. That's not really helpful... For one I'm doing this in C# and don't know anything about C++ (may seem strange, but I'm new to C# most of my knowledge for that comes from Java) So the whole C++ article isn't useful, I did take a look at it...but I couldn't even find it doing anything similar to what I want.

• .NET Development problem with CLR dll, but only in debuger

  I am making a CLR dll in C++, and testing its consumption in C#. For the sake of this thread, the CLR dll will be called ' MyCLRdll ' and the test propgram will be called ' MyTest ' I know the problem relates to the progress bar parts of the dll and test and cross threading What I don't know is why this problem ONLY happens in the C# debugger, or how to fix it. When I go into the Debug folder and double click MyTest.exe every thing works perfectly; its just when I hit the play button in VCS Express that the problems happen. The thing is MyCLRdll pretty much has to work in the IDE too because it is a devolpment tool "You can not alter a progress bar from a different thread," but ...Show All
