• Visual Studio 2008 (Pre-release) custom control problems

  i am writing a custom control to draw a series of polylines. i've managed to create a nice little program that does just that (and also draws the equivalent bar chart :-) ) but i am having problems converting this to a custom control. my first problem is that i do not know how to create DP's for an unknown number of user defined variables. for example i want the user to be able to say something like: <LineChart .........................> <Line> <"series of points"/> </Line> <Line> <"series of points"/> </Line> .................. </LineChart> (the reason for having any number of lines is that i want to be able to add and delete lines at runtime) my initia ...Show All

• Visual C# Inaccurate/Wrong calculations

  Hi, I working on a fairly large project in C#, combining numerous components such as SQL and DirectX. We all, however, seem to have come across a severe problem! We can't do basic arithmetic! For example, in VS.NET 2003, I need to subtract two UTC style time values - eg 11565456546546.1342345566 etc. double large_val1, large_val2; ... double difference = large_val1 - large_val2; Instead of the result I expect (and indeed the result shown in the Watch window during debug for large_val1 - large_val2), I get a servely rounded value instead - that is entirely useless!! Help!! I can do this in a standard command line / console application and everything works fine - why should there be any difference ! I have tried decimal, ...Show All

• Visual Studio Team System Modeling Solutions, Projects and References - Not Libraries

  I'm trying to consume the Application Design, System Design and Datacenter Design mentality in order to become facile in modeling applications. It has taken more than a decade of reading, trying and adopting for me to grasp what UML represents, what its useful for and how to work with it. Therefore, I expect a substantial learning curve in regards to SDM. In fact, if I am told there is not a curve, I know I'm not asking the hard questions. The point that has been asked in this forum regarding how to model a class library is the frayed end of a long thread in modeling processes. Below I have included a couple paragraphs from TN_1113 in the Team System \ Reference \ Technotes section of MSDN. The question I have is deep; it it do ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Animating Billboards Using A Single Texture

  I just finished a basic billboard class that is capable of reading in multiple textures and animating. However, I would like to read in a single texture file and be able to simply change texture coordinates to change the appearance of the billboard. Now, I could recreate my VertexBuffer each frame, but that would be a lot of wasted processing. Is there a way to dynamically alter the texture coordinates for VertexBuffer objects each frame Edit: As a bonus question, how do I enable the alpha channels in my textures Right now it shows up white. I am using the BasicEffect. Would I have to write my own effect just for that Seems rather silly but I will if I have to. Edit 2: As bonus question 2, how can I disable antialiasing of my textures I'm ...Show All

• SQL Server Dynamically changing task name displayed within ForEach Loop Container

  Does anyone know how to change the task name displayed within a ForEach Loop Container (or of the ForEach Loop Container task itself) based on a variable. I am pretty familiar with setting variable values during task execution and using expressions to alter task properties based on variables. I have tried using an expression to alter the value of the Name property of the ForEach Loop Container but the name of the ForEach Loop Container does not change during execution. Since the color of the various tasks change during execution, I would think that the task names could be changed as well. You can create checkpoints or if that does not fit your needs; you could write to a file or table on each iteration an the look at that. if you ...Show All

• Visual C++ Weird "Goto" statement

  I was reading an article entitled "The Case for Virtual Register Machines," where it had this code snippet: typedef void *Inst; void engine() { static Bytecode program[] = { iadd /* ... */ }; Bytecode *ip; Inst dispatch_table = { &&nop, &&aload_null, .... }; int *sp; goto dispatch_table[*ip]; iadd: dest = ip[1]; s1 = ip[2]; s2 = ip[3]; reg[dest]=reg[s1]+reg[s2]; ip+=4; goto dispatch_table[*ip]; } I've never seen "goto" used that way. I thought it could only be used for jumping to labels. Anyone know what this is about You are correct: neither Standard C++ nor Standard C supports syntax like this - they only support goto label. Having said that I have seen syntax like this in ...Show All

• SQL Server SP1 Installation note

  I was having a problem installing SP1, it would barely get started before it would fail. I found it had to do with having many of my databases on an external USB drive. I detached all of those databases, rebooted the machine and then attempted to re-install the Service Pack. This time everything worked fine. Just passing it along in case someone else ran into this. Just after it started a small dialog box popped up. It basically said the installation failed with the following error -- and there was nothing following it!! What I did is when the send an error report to Microsoft popped up - I looked at the contents and followed its link to c:\windows\hotfix\hotfix.log The contents (which are below) con ...Show All

• Visual Studio Looking for laptop, should be fine with .Net Framework.

  Hi, I'm planning to purchase a laptop but don't know exactly what minimum config is required to run it, specially in case of laptops. I have gone through lenovo C100, i think the processor is Pentium M. Does it support .Net without any problem " Can anybody help in this regard. Agreed with Brendan here. Laptops these days are fine to run .NET on, even ran .NET on a PII 350 laptop and that was ok, of course performance was a bit of an issue (was a reallly old laptop) you should be fine with any laptop these days for running .NET, and as said, .NET is software and has no real requirements to run on a specific set of computers/laptops. Personally, anything more than a PIII 800 would be more ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. When will the next beta of GSE be released?

  When will the next beta of GSE be released Jim Perry wrote: Why would that be helpful How does knowing when the next release is coming out help with testing the current version That is what we're supposed to be doing - testing. It would be helpful so we would know when we can actually begin testing. Right now a lot of us feel that the current XNA is not in any shape of usability since so much is missing. Simply put, there is nothing to really test with the current version other than that the install worked. The content pipeline is where we can really start testing as far as i'm concerned. YMMV, but that is just where I, and a few others stand at this point. ...Show All

• SQL Server Visual Studio 2005 The remote connection to the device has been lost. Please verify the device connection and restart debugg

  Basically I've been using Visual Studio 2005 for a few weeks now moving a Pocket PC project from 2003 to 2005.
