• Game Technologies: DirectX, XNA, XACT, etc. Problem with executing two DirectPlay Server under DirectX8 on the same server

  Hi, after I've googelt endless hours, I hope I'll find an answer here. I'm using DirectPlay for communication between clients and a server process. No we get troubles with the traffic on the network connection. So I've added a second network card and started the Serverprocess a second time (using the new IP-Adress). But when executing: DirectPlayServerCreate.Host AppDesc, DPAddress an error occured (Automatisierungsfehler / automation error) Here's the code in VB6: ======================================= Dim AppDesc As DPN_APPLICATION_DESC Dim lngErr As Long Call Class_Terminate With AppDesc Select Case mServerNr Case 2 .guidApplication = AppGuid2 'Guid created by GuidGen Case Else ...Show All

• .NET Development Exception: DataTable internal index is corrupted: '5'. on ...

  Hi, I have a problem with bindingsource component in framework 2.0. I have a combobox bound to a bindingsource which is also bound to a dataset with 2 related tables and a datagridview bound to the same bindingsource. What I want to do is : When the selectedindex property of my combobox changes, the corresponding cell value must be changed in the datagridview. But although the value in bindingsource changes, datagridview does not display the new value. That value is displayed after I move the mouse over that cell and make it invalidate its region manually. Another error I caught is the one that you can see as the subject of my post. I do not know why i have that message when I try to change the property of ((DataRowView)mybindi ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. How do I load a 3d mesh (.x file)?

  How do I load a .x mesh into my scene The space game seems to use its own format (which it names .swm), and there's nothing in the help. I've been scanning through through the classes in the Framework namespace, but I can't see anything obvious! Is .x the recommended format for objects like this (If not, I change my question to be about the recommended format :D) If anyone knows anywhere that has some nice .x meshes I can play with, that'd be cool too. The only one I have lying around is a chair, and that's going to look a bit funny running around my game :D Zumwalt wrote: So basically what you are telling everyone is don't bother with the SDK at the moment because it is pre-alpha still an ...Show All

• SQL Server update and delete query run very slow, why?

  a simple update query, like 'update order set f1001=1 where f1001=0', runs very slow, even got a time out error, since I put a datetime field as part of index. when I take off the datetime field from the index, everything runs as normal. Any idea Thanks in advance. Are there other process accessing (select, insert, update, delete) this table How many rows will satisfy f1001=0 What and how many indexes are defined on order table Is the datetime field part of the clustered index How large is are the indexes If column f1001 is part of the clustered index and the clustered index is quite big, and/or there are lots of indexes on the table and/or lots of rows met the f1001=0 crite ...Show All

• Visual C# Window blocked from opening after debugging

  Hi, Just so you know, this is my first post in this forum, so if I don't adhere to a protocol, let me know. I'm running visual studio 05, and I created a Hello World windows application with an OK button, label and a text field. When I debug or start without debugging, the window is somehow blocked from opening. It worked for a little while and I was able to use the window, but now it's back to opening for a split second and then closing. I'm on XP Pro SP2 Hi, I figured out some sort of workaround, or maybe a fix, but I changed the directory of the solutions I created to the desktop and now they work.

• .NET Development When passing in year to GetDaylightChanges the wrong start and end dates are displayed

  Been working on some things and looked at the example in GetDaylightChanges. Well since it is now 2007 and the daylight savings dates will change. If you put in a year other than 2007 say like 2001. The Start and End datetime properties are wrong. Run the example for GetDaylightChanges. The Example results show Year Start End Change ---- ----- --- ------ 1960 1960-04-03 02:00 1960-10-30 02:00 01:00:00 1970 1970-04-05 02:00 1970-10-25 02:00 01:00:00 1980 1980-04-06 02:00 1980-10-26 02:00 01:00:00 1990 1990-04-01 02:00 1990-10-28 02:00 01:00:00 2000 2000-04-02 02:00 2000-10-29 02:00 01:00:00 2001 2001-04-01 02:00 2001-10-28 02:00 01:00:00 2002 2002-04-07 02:00 2002-10-27 02:00 01:00:0 ...Show All

• Windows Search Technologies Unable to search mapped network drives like I could with Beta version

  I downloaded and installed the latest version of Windows Desktop Search. I had the Beta version before. It is a great tool! Here's my problem: when I had the Beta version I was able to search my computer's hard drive plus all network drives I have access to. Now I can only search my computer's hard dirive. I checked the "email and all hard disks" in the Desktop Search options and then selected "Index Now." Still I can only search my personal computer and not the network drives where I store virtually evrything.

• Software Development for Windows Vista UIAccess in Manifest Files

  I was trying to add a <requestedPrivileges> to a manifest file. Setting uiAccess = false works fine for my application. The documentation says that setting UIAccess = true, the application does not need to drive input to the UI of another window on the desktop. Applications that are not providing accessibility should set this flag to false. Applications that are required to drive input to other windows on the desktop (on-screen keyboard, for example) should set this value to true. Inspite of setting UIAccess = false, I am able to use SendMessage() and PostMessage() API's ( I tried closing other windows using these API's). So I am really not sure what previleges am I missing by setting UIAccess = false What does UIAccess = true actual ...Show All

I've tried the method GenerateMipMaps from the Texture class, but all generated mipmaps are entirely black. In the case you upload the texture content by your own you have to build the mip maps too. GenerateMipMaps works only for texture that are used as render targets after you have draw to it. ...Show All

• SQL Server Report Grouping

  We are creating reports in RS, and using a category grouping to group the results in a table. In some (but not all) of our tables, it seems that RS will randomly choose one of the response rows and pad the category column with extra white space (or invisible character) that, when the grouping occurs singles this row out and causes it to be displayed as a separate section. We can fix it, of course, by using a Trim() on the category.Value. However, I am more concerned with what is causing the behavior. We have looked in our source tables and the data is always consistently the same length. It appears that this only occurs when RS is bringing the data back for display. Is this a known issue ...Show All

• SQL Server composite nonclustered index

  Hi everyone, I have some problems on composite nonclustered indexes. I could not exatly understand their logic. In my opininon, suppose that we have a table called Order and we create a composite nonclustered index on this table for OrderID column and OrderDate column. So I am using this query; SELECT * FROM Order WHERE OrderID > 12 ORDER BY OrderDate So in here, I think our first research is based on OrderID and ten after ordering our data pointer according to the OrderID and then our index is converted to an index which is based on OrderDate while performing ordering. So is this correct Would you please explain this Thanks REAL WORLD SCENARIO lets say i have a junction table for student and subject which is a many to m ...Show All
