• Visual Studio Trying to print ends in 'memory corrupt' error

  Hi In the reportviewer control (2005 final edition) I can show a report but when I click on the print icon I get an error. On the first attempt I can choose from the available printers. After a long delay (some minutes) where the app is frozen I get this error message: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. Any further attempt to print does not offer the printer dialog but results in the above error message within the reportviewer canvas. This is true for all 50 or so reports I have created. The printers are regular network printers I have no problem to access from Office and other apps. Trying to print from the Reporting Services browser page ends in error Could n ...Show All

• Visual C# Converting strings to Chars and parsing file paths

  I'm stuck. I've been trying to parse a file path in a variable using .Split but I can't figure out how to use "\" as a delimiter char. I can't convert it to a char, and if I try to directly create it as a char I get the error "Too many characters in character literal". Does anyone know how to do this, or even better, does anyone have an easier method that I'm missing >> I've been trying to parse a file path in a variable << Additionally, you may wish to look into the methods of the Path class (in System.IO), where you may find the exact method you are trying to write. ...Show All

• Windows Forms Deploying files with a click once application

  I have an xsx file that seems to relate to an xsd file. I need to include both in my applicaiton. I can include the xsd in my visual studio solution but when I try to add th xsx it doesn't appear to get added; yet it is in the source safe explorer. I need to have this file deploy with my click once application since it is needed for an editor component piece in the application. It uses the actipro script editor and I need the language definiton files so the editor can recognize xml syntax and other languages and highlight them appropriately. I get this same warning/error for what seems to be the xsx file since that is the only file that does not get created when the application is published; there is not .deploy file for it.

• Visual Basic Determine in which Event i'm in

  Hi There, just want to know if it's possible to determine in which event i'm in... I want to create a error logging system, and in my try...catch statement, in the Catch(ex as Exception) part I want to write an error to a database table... but to make things easier, I want to record the current event, in which page i'm in, and all those stuff, just to make things easier for debugging, after the website has been launched, and any unforeseen errors that might pop up along the way... Thanks SJB Thanks, i'll give it a shot... so there is no way to do a response.write( get_event ) and then let it return, for example, eg: Page_Load ...Show All

I want to have a count of customers who were acquired on a specific date and I want this date to be related to my other measures, so I can show number of customer acquired and Revenue for a particular date period.

• Game Technologies: DirectX, XNA, XACT, etc. How to "publish" my own IGameService

  I've read Mitch Walkers article on the IGraphicsDeviceService and I understood it for the most part. Where I'm a little unclear is on the actual mechanics of creating my own GameService. The article says that the Graphics Component "publishes" an interface as a service. Does this mean the GameComponent internally actually creates a concrete instance of IGameDeviceServices and calls Game.AddService Here is an example: Lets say I'm creating a 2D Physics component that relies on an undelying "Physics" object (this object does all the simulation for rigid bodies). I want to allow others to either use my PhysicsComponent or create there own component that would could still interact with any other higher level physic ...Show All

• Windows Forms Checking If Date Value Is Null

• Windows Forms MTAThread and AutoComplete

  I need to use the WaitHandle.WaitAll and TextBox.AutoCompleteMode. The problem is that the first requires MTA and the latter STA . Is there any way around this rich Hi Rich, Based on my knowledge, to invoke a method on UI Control on the main thread from another thread, we recommend you use the Control.Invoke which is implemented by SendMessage. Due to the Winform is not thread safe, we do not recommend you put it into MTA thread. Also .NET do have more payload than Win32, because if the .NET code underlyingly call the unmanaged code, it need P/invoke or COM interop marshalling(if .NET code call an unmanaged COM, we also need marshaller). Also for .NET code to run, the .NET runtime need to JIT the MSIL to nat ...Show All
