• Visual Basic Encrypting File System Additional Features

  Hi guys. My thesis for college is a system that encrypts and decrypts images and text. Obviously, the main issue here will be security, but here's the thing: to satisfy my panelist, he says that I should add more features that reaches beyond security, meaning give more features which are just about security. So, I was wondering if you guys could help me out by giving me some ideas for more features beyind security. This would greatly help me. Thanks guys. alphonso, Thank you for the question. Here I would like to recommend you an article titled How to encrypt and decrypt a file by using Visual Basic .NET or Visual Basic 2005 in the following link: http://support.microsoft.com/kb/301070 This artic ...Show All

• .NET Development How to attach NotifyIcon to the Windows Service in C#

Sunil Dutt You can't/shouldn't. Services do not have a UI because they run under a different desktop than the logged in user. Instead you should create a separate WinForms application with the notification icon. You can add your application to the user's Startup group (like SQL Server does) or add an entry ...Show All

• .NET Development Too many Updates to do

  Hello. I'd want to know how does a .net application work when we have to do too many updates, I want to say for example 1000 updates on a file at the same time. For only one update, if I'm rigth, we send to a procedure: the connection and the sql statement I want. The procedure, open the connection, execute the sql statement and close the connection.

Another question, please: If I have 10000 updates to do. Must I set something special I say that because la connection is opened much ti ...Show All

• Internet Explorer Development IE7 File download issue

  IE7: To download a file when i click on a button in a page, a new browser window is opened and if the response in the new window has the response header " Content-disposition " set to " attachment; filename='<fileName>' ". Then the file is not downloaded. The downloading dailog is shown but never completes. Looks like new browser window and content-disposition don't go hand in hand. Is this an expected behaviour. If so please explain why We are seeing a similar problem. We set window.location of a frame in our application to a URL that downloads a file - http://docserver/app/dowloader. The response includes the content-type and content-disposition header and the contents of the document. This works gr ...Show All

• Visual Studio Express Editions Can I replace 7 chars with 5 chars at the beginning of a string?

  #include <string> using std::string; s.replace(0,5,"12345"); // replace the 1st 5 characters s.erase(5,2); //then delete the superfluous 2 or is there a better way   iccle wrote: Not really in this case, as standard string just moves the "begin" pointer to the start of the valid data, it only reallocates memory if there is not enough space in the string. Oh right iccle, cheers but if some chars are 'deleted' from the middle of the string does a char * naturally jump to where it should have been or does it hit a NULL where the deleted (replace 3 with 2 or nothing) char and then think the string has ended Oh wait, each char has a begin pointer pointing to the next char which is automati ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. general use of XNA vertex types?

  I am trying to create some methods to manipulate various parts of the XNA vertex structs. I want to be able to pass all the different vertex types as arguments to these methods. Because they are structs they don't derive from a base class other than ValueType. If I use ValueType as the parameter I don't have access to the propertys of the vertex. Is this a case where refelection would be usefull Can anyone help me find a way to write a method that can access the position property of any type of vertex. I hope I have been clear enough. Thanks. If at all possible, can you move your processing to build time At build time, you can make use of Microsoft.Xna.Framework.Content.Pipeline.Graphics.VertexContent a ...Show All

• Windows Live Developer Forums How to update the pushpins location based upon live GPS data

  I am working on gathering real time GPS location data and displaying that on the map. I see we can add pushpins but I do not see a way to keep the location lat/lon up to date with current position data. Do I simply just update that pins' VELatLon or is ther another technique to do this Thanks Rich G There is no way to change it that i'm aware of. You need to delete it and add it at the new location. The SDK shows you can delete a specific pin or all the pins. John. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Methods to check 2D rectangle collision?

  I enjoyed Win32's IntersectRect() before for this kind of work. Is there a similar method for 2D collision I think you'd be better off just writing your own function to do the same thing as the BoundingBox.Intersects method, accept in 2D. It's a pretty simple function, although the logic is backwards. You actually test to see if the objects aren't intersecting and return the inverse value. For a BoundingBox it would look like this: public bool BoundingBoxIntersects(BoundingBox bb1, BoundingBox bb2) { return !((bb1.Min.X > bb2.Max.X) || (bb1.Max.X < bb2.Min.X) || (bb1.Min.Y > bb2.Max.Y) || (bb1.Max.Y < bb2.Min.Y) || (bb1.Min.Z > bb2.Max.Z) || (bb1.Max.Z < bb2.Min.Z)); ...Show All
