• Visual Basic In the registery?

  I have written a program that requires a password to be created when it is first run, this is then encrypted and stored on the computer C:/Test.txt . the next time the program is run you enter your password, which is encrypted and compared against the encrypted password on file, and if they match you can use the program. I don't think storing the encrypted password as C:/Test.txt is a good thing, so where is the best place to hide it away, and how is it done Any help, advice or interesting articles will be welcome. Thanks NuyN, But to get the file I just use If File.Exists(Passtxt) Then Passtest = True btnPassCreate.Text = "Enter Password" if it doesn't exist then you create a ...Show All

• .NET Development security issue

  I have a security issue: My program can read files from network in console mode but not in service mode. I know it 's some kind of security issue.But who can give some suggestions about that or a specific link. Thanks in advance In console mode the security context that the application runs under is your userid. In service mode you need to configure the identity that the service will will 'Run As'. You can configure service identities in Computer Management->Services. The identity that you configure in here should have sufficient privileges to access the network resource. You can also configure identities programmatically by customizing the service installer (set account, username and password) o ...Show All

  Hello all I am using a TabControl to present data. before navigating to another tab I need to check whether the data in the current Tab was saved or not. I do this like this and it works great. BUT I present the user a yes/no/cancel dialog, asking whether to save the data: Yes - save the data and move on (MoveOn=true) No - do not save the data but move on (moveOn =true) cancel - stay in the current tab (moveOn=false) where e.handled = true (Cancel) it worked great.

• Game Technologies: DirectX, XNA, XACT, etc. NoSuitableGraphicsDeviceException was unhandled

  Let me just say at the outset that I know nothing about C# (yet) and am trialing the XNA beta to try and get into it. I do know VB and some C, however. Once I had everything installed, I tried a few example programs including the Spacewar project, but I cannot run any of them. They build fine, but I can't run the .exe, and it crashes and asks if I want to send a report to MS. If I "Start Debugging" instead, I get the error "NoSuitableGraphicsDeviceException was unhandled" on the "this.GameComponents.Add(this.graphics);" line. I have no idea where to even start. Is it my install My PC My hardware The program I'm trying to run Once I know the environment is actually working, I can begin the learning! ...Show All

• Windows Forms Best way to display large datasets?

  I have an application (VB.Net, SQL Server) in which users routinely need to display large amounts of data. We are currently getting the data from the database via stored procedures. The data is then loaded into ADO.Net data tables and data sets. The data is displayed using a DataGridView class which uses a DataView as a binding source. We are finding that when we load large amounts of data into the datagrid there is a considerable delay, which seems to be much larger than a similar amount of data being displayed in Qurey Analyzer. Does anyone have any suggestions for speeding up the data display, or are there better objects to use for displaying large amounts of data TIA Ron L Damiaan has gived some detail advices,i will g ...Show All

• Software Development for Windows Vista Vista and XP Styles on non .Net C application

  Hi Our application is developed with Visual Studio 2003 in C. It is an unmanaged application and does not use MFC. To get the look and feel of XP on the common controls, buttons etc we used the technique of distributing a seperate manifest file with our application. This worked fine under XP. Under Vista however, two problems occur. 1. If we run the application the fact that the manifest file is there seems to be ignored and the xp style look and feel is not used. 2. If we set the application to run in WIndows XP compatibility mode, the xp styles appear and seem to work ok except for Header controls. On a header control the width of all the columns in the header is initally displayed as 0 so the various sections of the hea ...Show All

• Visual Studio Express Editions Mouse movement in C#.

  How exactly is mouse movement achieved in C# I know that in VB.net, it can be implemented using the gdi32 MouseEvent library, but what I truly need to know is how to achieve it in C# (along with simulated clicks, for macros). how do you mean mouse movement do you mean for example the mouse moving from the current position to say, the left hand side of the screen if this is what you mean, try this:   Cursor.Position = new Point(Cursor.Position.X + 10, Cursor.Position.Y + 10);     this will move the mouse from the current position, either way, and add 10 to the co-ordinates Mouse is known as a Cursor when coming to develop with it.
