Game Technologies: DirectX, XNA, XACT, etc. Assign to Vector2?
This is probably an easy question, how do I assign to a Vector2 This was my first bad guess: Game1.Players .Position = (0f,0f); but it didn't work, I know I can assign to the .X and .Y of the Vector2 but I want to do it in one simple step. Also can you do it without creating a new Vector 2 Cheers Alfons Is there a performance difference between using... position.X = X; position.Y = Y; ...and... position = new Vector2(X, Y); ... There shouldn't be any difference in allocation on the heap because Vector2 is a struct and structs are allocated on the stack (so no GC problem with the Xbox360). But is the compiler able to allocate directly to 'position' rather than a temporary stack variable ...Show All
SQL Server Anyone know how to create a "Table of Contents" (TOC)?
How do I create a Table of Contents (TOC) for my report Thanks We solved this by creating a .NET custom render for PDF. We manipulated the multiple reports into one report using SVG and then created a TOC at the front. There are only two reporting packages that meet this TOC requirement. Acuate and the newest Crystal Reports. ...Show All

Smart Device Development CabWiz Info
This is just a quick post to hopefully save someone some of the pain and agony that I have suffered over the last 2 days trying to get a CAB built for a new PocketPC app. If CabWiz reports an error similar to: Error: CAB file "D:\CabFile.CAB" could not be created one of the first things that you should check is that you do NOT have 8.3 file naming turned off. If registry entry HKLM\SYSTEM\CurrentControlSet\Control\FileSystem\NtfsDisable8dot3NameCreation is set to 1, then CabWiz will either not work or will only work intermittently (depending on whether you are working in a directory that has short names or not). If it is set to 1, change it to 0 and then reboot. You will also need to recreate all existing directories that do not ...Show All

Visual Studio Checking out
Hi, How can I force an automatic check out when I edit a file, it some times works in this way but some other not. The SorceSafe option "Always check out the working folder version of files" is always disable Thanks JIRO Hi, The automatic checkout is controlled via the Visual Studio Tools->Options dialog. Navigate to the Source Control->Environment page, and make sure that the combo box for "On Edit" says "Check Out automatically" The SourceSafe option "Always check out the working folder version of files" is not related to automatic checkout behavior. It actually controls the version you are checking out (whether you check out the latest version available on the database or the last version you have gotten in to ...Show All

Internet Explorer Development IE7, OE6 Printing problems with headers
Having an intermittent problem printing To: From: CC: Subject: Attachments: headers on emails. Usually happens with larger emails or emails with large attachments or emails that have been replied to or forwarded from other people. Have installed Generic/text printer and sent the email to this printer but sometimes the headers are still missing even printing this way. I have if I open the offending email and highlight just one or two words in the text of the email eg Dear John and then print the email using my HP printer (not as text on Generic printer) - the headers then print and so does the selected words.

Smart Device Development Unable to create cab files in visual studio 2005
Hie, i think i am facing the same problem, so i just reply here instead of starting a new thread. if this isn't the same problem, i will create a new thread later. i followed the how to article on using smart device cab project to create the cab files. i successfully created the cab file and when i copy it to the device via activesync, it install successfully. but when i package it into a installer and use ce application manager to install, it say this is an invalid setup file. so i open the cab file and compare it with the sql ce cab file. and guess what, it is different.

Visual C# Value not appearing in textbox
In a nutshell... I'm new to working with C# in Visual Studio and I have a dilemma. I am populating an arraylist with datetime values via a winform. When I click a certain button on that form I want to see the second arraylist item appear in a textbox. The code I'm using to do that is: ReturnedTimesheetTextBox.Text = theCurrentEmployee.Timesheet[1].ToString(); However, clicking the button produces this text in the textbox: EmployeeProject.Timesheet Now, "Timesheet" is the name of a property which is of a type ArrayList and which resides in another class. "EmployeeProject" is, of course, the name of the VS project this exists in. Can anyone offer any help as to why I'm not seeing my datetime value app ...Show All
