• Visual C# Help with PrintForm PowerToy

  I downloaded the Print Form powertoy for Visual Studios. My problem is that I have a form with is scrollable, but when I print the form out the printer stops printing about halfway down the form. I suspect that it may have something to do with the the current focus of the form, but even after adding the "Scrollable" option to the code it still does not print the entire form. Here is my code: private void toolStripButton1_Click(object sender, EventArgs e) { printForm1.PrinterSettings.Copies = 2; printForm1.Print(this, Microsoft.VisualBasic.PowerPacks.Printing.PrintForm.PrintOption.Scrollable); } The other question was that the examples in the included docs are in VB, and sense I am using C# I was wonderin ...Show All

• Visual C++ C and .net

  Hi, I've lots of programs written in C (not C++) and I want to include some .net framework in them. How can I do I've Visual Studio.net 2005. Thanks. SerialH well it is prbly practically impossible to use .NET from a C compiler, but.... since C++ is backwards compatable with C you may be inluck. It is possible to call a pointer to a managed .NET class in native C++. first make a native class in VS, than declare the managed object you wish to use like so: gcroot<ManagedClass^> MyObject; Now copy your old C code into the class in an appropriate place; you can now use C/C++ to do stuff with the .NET MyObject Also don't forget to include vcclr.h, otherwise it won't work. ...Show All

• SQL Server CmdExec Step in SQL Agent job not catching error

  I have a SQL Agent job on SQL Server 2005 that uses a CmdExec step to run a C# console application. The same job used to run on a SQL 2000 server and whenever the C# app failed, it raised an error and the SQL Agent job would fail as well. Now in 2005, the same error is raised, however the SQL Agent job is left in an "executing" state, preventing me from using a notification to alert me to the failure. Has anyone run into this same problem Any suggestions Thanks ...Show All

• Smart Device Development SystemProperty.Date/Time data type

  Hi All, I am trying to use the managed state and notification broker API (Microsoft.WindowsMobile.Status.SystemState) and am struggling with date / time values. For example: SystemState.GetValue(SystemProperty.Time) returns a byte array of length 8. Does anyone know what this represents and how to convert it to a usable time value Ultimately, I want to launch an application when the time equals a specific value but I need to understand what to use for SystemState.ComparisonValue before I can do this. Thanks, Joe Hi Fabio The binary representation of a 64 bit integer can be expressed as an arry of bytes.

• .NET Development underlying connection is closed

  we have thick client winforms application which consumes a webservice . this throws up an excepyion of type System.Net.WebException "Underlying connection was closed. An unexpected error occured on recieve" We have tried to override GetWebRequest method in Reference.cs by setting KeepAlive = false. But it does not solve the issue. The timeout on IIS has also been increased without much luck. Any thoughts is greatly appreciated Have you checked to see if the webservice request is executing correctly or if it's generating an exception If an error occurs on the server side it would stand to reason that the connection would be closed. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. N00b Maths question - calculating radian angle for rotation of a sprite based on two points in 2d

  Apologies for my poor mathematics here, but I need to ask the greybeards for some advice: I have two points on a 2d plane, offset so there is one "top-left" and another "bottom-right". I need to join these two points with a straight line by scaling a single dot sprite from one point to the other. If I know the x,y co-ordinates of both spots, I can get the overall length of the scaled sprite, but how do I calculate how far I need to rotate the scaled sprint around one end point to "join" the points together Thanks in advance for any help you can give.

• Visual Studio Team System Rename command is very slow

  Hi, I have to rename thousands of files in TFS. So I wrote a small tool to do it. However I found it performed very poorly. It took 5 minutes to rename 200 files. I have tried using tf.exe command and the VersionControl API. Both of them are very slow. Is it a known issue Thanks, Heng-yi Hi, It's actually a lot worse. I let the rename command run overnight. The following is the result I got back in the morning. I ran 6 batches of tf.exe command.
