• Game Technologies: DirectX, XNA, XACT, etc. Shader states, etc? (HLSL effects not working right)

  I'd like to call upon all the shader gurus here for some help :) I've been experimenting with writing some of my own effects, meaning I'm a HLSL newbie, and have been using NVIDIA's FX Composer to do my work. After producing a cool (albeit simple) effect, I decided to try using it in my little model viewer. The problem is that the way it shows up through XNA is different than the way it shows up in FX Composer, and I can't figure out why. You can find the code to my effect here: http://www.hiranipra.com/data/help_attach/gb1_shader.txt - it's just fairly simple environment mapping-ish stuff. A screenshot of what it looks like in FX Composer: http://www.hiranipra.com/data/help_attach/FxComposer1.jpg - it's hard to tell, but the ...Show All

• SQL Server Native Client ignores ANSI_NULLS setting in database

  Hello, I'm using the SQL Native Client to connect my VB6 application to my SQL Server 2005 database. My SQL Server 2005 database has ANSI_NULLS turned off. I have a query embedded in my VB6 application that uses the syntax "fieldName = NULL" in the WHERE clause. When I execute the query via the SQL Native Client, the query returns zero rows. When I execute the same query via the old OLEDB driver, the query returns many rows. If I change my query to "fieldName IS NULL" syntax, the problem goes away. However, I am more interested in figuring out why ANSI_NULLS are turned on when using the SQL Native Client even though my database has them turned off. Is there a connection string property that I can use with the SQL Na ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Managed Direct3D 10

  Since XNA only supports DirectX 9.0 Where is Managed Direct3D 10 I hope there will be Managed wrapper for Direct3D 10 thanks   Jononet wrote: XNA only lets you use an entire window for the graphicscomponent. This is not much use to people like me that make business apps with 3D elements in them, for us being able to create a device in a control within a Windows Form is essential. Our applications are never going to hit the XBox so we would end up moving away to OpenGL libraries rather than use C++ which is too much of an overhead in a RAD environment. Though it's not stated in the docs, XNA does in fact let you manually create the device and render to a control in a ...Show All

• Visual C# partial class and conditional compiling

  Hi, I have a following class declaration: #if LOW_LEVEL public sealed class Core #else internal sealed class Core #endif { } Based on the conditional compiling directive I want to control the access to the class. I do not define the LOW_LEVEL compiler directive (either in code or in project settings). I compile this class. It works fine. But when the class definition is split across files like below: //class1.cs #if LOW_LEVEL public partial sealed class Core #else internal sealed class Core #endif { } //class2.cs #if LOW_LEVEL public partial sealed class Core #else internal sealed class Core #endif { } and when I compile the two classes now ...Show All

• Visual Basic "Enable Application Framework" option in project properties messing up label text

  I have a COM project (.NET) that contains a form with a label. It gets called by an unmanaged, non-.NET application. The text in the label control gets squished. I've written a little sample app that I can duplicate 100% of the time to get it to squish or to not squish. This is what my sample app does. I have AWinApp, which is a .NET windows app and MyCOMApp, which is a .NET COM app that contains a form with a label. AWinApp calls MyCOMApp.MyForm.ShowDialog() The text in the label gets squished if the "Enable Application Framework" option is not checked from AWinApp project properties. See screenshot below: http://new.photos.yahoo.com/chango_butt/photo/294928804136692661/1 This is how it should look (I checked "E ...Show All

• Visual Studio Express Editions How to select multiple dates in MonthCalendar winform control

  Hi, i want to select multiple dates (not contiguous) on MonthCalendar winform control, but i can only do for a range of dates that are continuous, but not random ones. Also, i want to programmatically select a list of dates, and the selection should be read only on the front end. Users should be able to view the selected dates, but not change them. Thanks, Srinivas Yelamanchili The MonthCalendar properties that indicate selection clearly do not support this. You could use BoldedDates to indicate selected dates... ...Show All

• Windows Forms datagridview vertical scroll bar

  Is there a way to make the datagridview have a perminant vertical scroll bar There was a way with the datagrid, but can't seem to find it in the datagridview. Thanks in advance. I am having the same problem. *Maybe* I am using the wrong class. What I am trying to do is to add a bunch of rows to a control dynamically using the datagridview's Rows' Add method. I add the rows one at a time periodically over some period of time say 1 or 2 minutes. When I hit the exact number of rows that the DataGridView can display the entire application locks up. Also the DataGridView is not able to create the scrollbar for the control. The area where the scrollbar would appear is a little funky, as if the paint metho ...Show All

  For .Net FW2.0, I can detect the changes on datagridview by subscibe the event "RowAdded","RowRemoved","CellValidated". Step by Step: 1.Write a method Eventchanged(object sender, EventArgs e), I will set a bool value to be true; public void Eventchanged(object sender, EventArgs e) { this.detectObject.Ischanged = true; } 2.subscribe the event after form loaded; this.dataGridView.RowAdded += new EventHandler(Eventchanged); this.datatGridView.RowRemoved += new EventHandler(Eventchanged); this.datatGridView.CellValidated += new EventHandler(Eventchanged); 3.Through the local variable detectObject, I can know if user have changed the content in the control datagridView.

• Visual FoxPro A (simple I suppose!) grid question ....

  Hi all! I used to work with VFP a long time ago and I have almost forgot most of it so I ll need your help here! :) I have a table (called myTable) with 4 fields (3 of C(20) and 1 Memo- ID,Title,Location,Descr.). When I am displaying that on a grid, I do that through a new cursor called myTable_cursor. But in the cursor I added a new field because what I wanna do is to display the first 20 characters of the memo and if the user wants then to double click on the memo cell and a new window to open and view all the memo field or edit the memo. So my problems are: 1. Whatever I put in the click event in the textbox cell in the grid (in the correct memo column) it does not respond! Any solutions here 2. I use a cursor to display ...Show All

• Software Development for Windows Vista How to correct the "Unidentified Publisher" message

  There is an earlier post ( here ) detailing how to get the correct publishing details in the User Account Control window but it described the process of getting the software through the "Works with Windows Vista" Program. My question is: To get the correct publishing information in this window, is it enough to digitally sign the software using a software publishing certificate from versign or does the software have to be submitted to the "Works with Windows Vista" program I've signed an app using a test certificate and it's made no difference to the User Account Control window. Thanks in advance. No, you only have to sign with a valid Authenticode certificate. Do not forge ...Show All

  I am making a user control where 3 of the propertys are of the type Voltage, witch is a self defined object. consisting of a float and a enum.
