• Visual Basic Using FORTRAN in Visual Basic 2k5

  I'm kind of new to programming, so if anyone can help me out I'd appreciate it. I'm writing a program that has the majority of its computational work written in FORTRAN. The FORTRAN program takes a file input which I have create successfully, but I don't know how to declare and call the FORTRAN library from VB. Can anyone help me out JE You simply add the reference to the fortran dll. If its a COM or .NET dll then you should just be able to use the classes, methods in this dll. If it is not a COM or .NET DLL but an unmanaged API, then will need to use the declare statement or dllimports statement (they both equate to pretty well the same thing) to call the unmanaged API. ...Show All

• .NET Development Can't step into web service in debugger

  I have a windows forms application that calls a c# dll which calls a web service (on my local web server). I wrote the code using VS.NET 2003 and had no trouble debugging. I have recently upgraded to VS.NET 2005 and can no longer step into the web service. When I set a breakpoint in the web service and start the app, I see an icon next to the breakpoint that says no symbols have been loaded for the document. I have added the following line to the webconfig file: < compilation debug = " true " > The configuration Manager shows all projects being built with debug on and when I look at the property pages for my web service, the asp.net debugger is checked. Does anyone know what I am doing wrong ...Show All

• Visual C# Read binary, convert to hex

  Ok, i have an executable that i want to be able to edit the hex values of, but i can't find anything that will read the hex from the file... I was wondering if it might work if i did a regular BinaryRead and just converted whatever it read from binary to hex, then edited that and converted it back to binary and do a BinaryWrite. Would that work the same as if i had directly edited the hex I'm pretty new to this, but im just trying to basically end up with 1. Read the hex of the file. 2. Change it according to what the user enters. 3. Write it back to the file. thanks a lot! !!! Thank you sooooo much, your a genius man ! Works great and im good to go! thanks again! ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Orienting 3D objects along a velocity vector

  I'm working on a bullet/missile class for my 3D game and I'm struggling with trying to figure out how to construct the rotation matrix to have my mesh oriented with the direction of my velocity vector (a Vector3). It seems like it should involve two rotations (since one axis will be the up-vector) and probably a little bit of Math.atan2 magic. Can anyone help me out Divided by the product of their magnitudes. I'm typing this from work and don't have the XNA docs in front of me and can't remember the function names but mathematically it would look something like this. v1=natural direction v2=direction you want to point. vaxis=cross_product(v1,v2) angle=acos( dot(v1,v2)/( v1.Magnitude()*v2.Magni ...Show All

• Software Development for Windows Vista Installation Directory Write Access Issue

  Hi, I am a developer for a commercial program and we are working on a Vista-aware release of our product. It is a large install (6 CDs) abd is currently all put in Program Files under XP. The Microsoft suggestion of putting program executables and static data in Program Files and all other stuff in the appropriate users/... directory is not practical for our application. I have never liked that model. It makes things complex both for users and programmers. It is a road that we simply will not follow. The problem, of course, is that users don't have write access to the Program Files folder unless they explicitly and manually set it. We could require the users to do that but this is not a happy solution and we probably will not do that. W ...Show All

• Visual C# How to set a excel file readonly?

  Thank you To set the information/attributes, we use the File.SetAttributes in the System.IO namespace: System.IO.File.SetAttributes( "File.xls ", FileAttributes.ReadOnly); and thats it! to set multiple attributes, simply add another FileAttribute (OR) System.IO.File.SetAttributes( "File.xls ", FileAttributes.ReadOnly | FileAttributes.Hidden); would make it readonly and hidden.   To undo this, or rather set the attributes back, then you need to use FileAttributes.Normal, on its own: System.IO.File.SetAttributes( "File.xls ", FileAttributes.Normal);   does this help ...Show All

• Smart Device Development POOM: Can't delete appointment if using IAppointment*->Display

  In Windows Mobile 5 for Smartphone POOM is now supporting the Display method in ITask, IAppointment and IContact (Display was not working in pre-WM5 versions). The Contact card and Appointment card also have a menu connected with the right soft key - the menu enables to beam the contact or the appointment, edit the contact, etc. In the Appointment card, however, the "Delete" menu item is not working. The same command works perfectly in the Contact card - you get a dialog asking to confirm the operation and, upon confirmation, the contact is removed. With the appointment menu, no way - the appointment is retained. Tested on two different Smartphone models from two different OEMs. Is anyone aware of this issue and of a workar ...Show All

• Visual C# Relative Paths (or CurrentDirectory) wrong if called with arguments?

  Hello Community, i got a very strange behaviour here. For example, i am working in the directory: C:\Test. When I call my assembly, abc.exe, the Environment.CurrentDirectory (or all relative paths) are C:\Test. Now, my file takes files as arguments (like an Editor). So when i drag and drop a file (test.txt) on my exacutable, the Environment.CurrentDirectory variable (and relative Paths) change to my default User directory which is something like C:\Files and Settings\Username\... and so on Why does this happen How can i get the Path, where the File is located I am working on .Net 2.0 beta 2 Thanks in advance!!! Your help is very appreciated. Thomas  You need to view the command line arguments and no ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Model Exporting From Maya (.fbx)

  I have a question and concern regarding the .fbx model exporting from Maya. Problem: Whenever I load a model into my game that has been exported using the latest .fbx exporter plugin from Maya the model is arranged such that some of the pieces of the model are lined up along its x axis. I did some research on the .fbx file format and found out that while it was designed to be an open document 3D model format, it has been grossly revised by just about all modeling programs which have edited it to suit. Which is why you can't export a model in Maya and then import it into Max and expect it to be the same. My question is this, being that the .fbx file format is flaky at best; what make and version of the .fbx exporter/importer is XNA designed ...Show All
