• Game Technologies: DirectX, XNA, XACT, etc. My 2 Cents on pricing...

  I have been actively reading as much information on XNA as possible. I would like to thank the members of the XNA team who have been providing great information about the tools and framework. I have already posted my thoughts about the fee on David Weller’s blog. I understand completely why the fee is needed for development. However, I do feel that the fee could be adjusted in such a way that the end result would equal more profit for Microsoft and a larger market for the hobbyist game programmer. While browsing David’s blog today I came across this comment to his latest post by Bladestar: “ That should create a dent; I'm not sure if "XNA Creators Club" it's the proper term. Since even people that have no interest ...Show All

• SQL Server Dymamic connection strings in SSIS...

  I was reading through the following post regarding dynamic connection strings: http://forums.microsoft.com/TechNet/ShowPost.aspx PostID=812814&SiteID=17 In this posting they talk about setting up a configuration file to setup the connection string, but I am not sure how to apply that connection string to my connection manager. When I go into my configuration file, I can see the connection string, and when I go into the advanced properties of the connection manager, under the "Named ConnectionString\FileName" property, I set the property value to the name of my configuration file, but when I test the connection I get an error that the connection string property has not been initialized. Can someone please assist me w ...Show All

• Gadgets How to make ActiveX Callback functioning

  I cannot get the office name control to call back to a jscript eventhandler. (Office 12 installed in my case) The page works well if just rendered in a browser, hoever it does not function when run in a gadget. The thing that fails is that the eventhandler is never called when a buddy chnages state. The callback function is registered by calling the OnStateChange function as shown below. is such a callback not allowed (or only with additional magic ) I'd also appriciate suggestions for debugging this as I am not quite sure how to approach this Jos Indeed, That shows the same effects I see when run as gadget. Do you have suggestions how to find where the security (if it is indeed that) is restrictive and how it could be ad ...Show All

• Visual Studio Remote debugging with VS 2005 when TCP/IP filtering is on

  I have an embedded XP environment where TCP/IP filtering is turned on and only a small number of ports are allowed to be open. With MSVCMON, we knew which ports were needed and we'd open them up to allow DevStudio sessions to remote debug. With VS 2005, MSVSMON "seems" to allow you to select a port (like dbgserver for Windbg), but when I try to connect I still am told that I cannot connect. I did some network sniffing, and saw that VS did an initial handshake on the specified port, but then switched to some other, random port, which is not opened on the server and therefore led to the debug session failing. Can anyone tell me if there is a way to use MSVSMON in this type of environment where I want to know (and control) which por ...Show All

• Visual Basic Making settings mandatory and trusting locations

  Hi everyone, I'm working in a 300+ workstation school site which has 1500+ users. I have installed VB 2005 and setup the settings that I want them to have. How can I restrict Visual Basic so that it's 'profile' settings stay the same for each user after they log off and without an error message saying that it 'can't be written to I have tried restricting the settings file and it gives me an error.

• Internet Explorer Development IE7 webbrowser control and SWF/PDF files

  My app embeds a webbrowser control. One issue I notice after installing IE7 is that if I browse directly to a SWF or PDF, the page is blank. If I browse to an html page that embeds a SWF, it works fine. This also works fine in IE6. Am I missing a flag/setting when creating my webbrowser control ...Show All

• Windows Forms Editing (specifically deleting) from hosted designers

  Hi there If anybody can help me, it will be greatly appreciated. I've used the DesignerHosting sample from the MSDN magazine (article "The Perfect Host...", and I'm trying to combine that with a TestUndoEngine example I've also found. My problem is that even when invoking StandardCommands.delete after a click on my menu, nothing happens. Now I've noted that all the edit functionality is disabled when you aren't working with a CodeDOM loader in the DesignerHosting sample, but I can't figure out what I need to implement in my BasicDesignerLoader so that deletion works, or even why this functionality needs to be disabled. I'm also not sure what happens behind the scenes when you delete something in a CodeDOM loaded form in ...Show All

• .NET Development Possible Problem With Sockets 2.0 Implementation in .NET 2 with McAfee Software?

  McAfee (Privacy Filter and Personal Firewall) installs it's own TCP/IP driver layer. This new driver does not seem to support sockets correctly. When attempting to connect to a remote server IPv4 TCP/IP using the Async BeginConnect you get "not supported on this object type" (unistall the Mcafee driver and it all works fine). If you do a sync connect using Connect the connection is established . However, if you then try to do an async send after connecting you don't just get an exception you get a full blown unmanaged general protection fault. This seems to be a pretty big problem has anyone else out there experienced it or maybe got a work around To answer your previous question, I don't know ...Show All

  Hello, I have got some questions about working with a Viewport3D. 1)How to develop a method which converts the view of the Viewport3D to an image file and saves it on the hard disk 2) I have got some spheres in the Viewport3D. How programically make them visible or hidden 3) I want to add some text to the Viewport, for example, on the one of the spheres there could be written "Earth".

• Visual Basic ADO.net dataadapter.fill

  Hi, I have two tables in my database: tb1 and tb2. tb1 will be inserted into tb2 with these conditions: 1.) if primary key to be inserted is already existing in tb2, then the data in tb2 will just be updated using values of tb1 2.) if primary key to be inserted is not yet existing in tb2, a new recorded will be created in tb2. I used a dataadapter to fill the datatable and a bindingsource. Also, I used execute non-query command to insert/update the data in tb2. everytime i update/insert a record in the database, my datatable still contains old table records (it doesn't have the data i inserted and contains old data before updated). in this case, i have to issue another da.fill(mydatatable) to refresh.... which is so slow espe ...Show All
