Create Logon Using SQL Server Similar To The Windows Live Logon
Aug 20, 2011I am wanting to create a logon similar to the Windows Live logon, so in other words. user has frmLogon and is located in Australia. The user enters his/her details and then the program connects to a server in the United States and checks the Username and Password to make sure it is correct if it is correct it allows the user to logon and move to the next stage, if it is wrong it will give him an error message. I am wondering if anyone has a tutorial or source code laying around that I can rip apart and see how it works. I want to put the database on my server and connect to it from my desktop using the logon form.

Feb 8, 2012I am using VB.NET 2008.
On this Windows 7 Professional SP1 machine, when I run the following code in the program
FileCopy(sServer & "loglog.txt", Application.StartupPath & "log.txt")
I got the error "Logon failure: unknown user name or bad password."
sServer is 1 of our server machine.
The Windows 7 machine already logged in to the sServer as administrator, and it also login to the Windows 7 machine as administrator. I run the VB program as Administrator (right click - Run as Administrator).
In the Windows 7 machine I can go to Windows explorer and copy the file manually from the sServer machine to the Application.StartupPath folder.
Logon Failure :: Unknown User Name Or Bad Password?
Apr 25, 2012When my application starts, one of the first thing it does is load a list box with data from an Excel file stored on our server.To prevent an issue I had with two or moreengineers trying to load the data from the same file at the same time, I added code that copied the Excel file to a temporary file (which is,hen, deleted when the data load is done).This has been working fine up until last week. Last week our company moved to a new building.The move included servers and all. Suddenly I'm getting inundatedwith complaints from engineers about my application.It seems that they started getting the following error

Feb 18, 2011I created a program with all our clients user name's and password that will be used to log on a web page from our company so i can modify there settings. So far so good i created a form with a combo box to pick a name and then a simple click on the button opens form2 with a browser in it. This browser automatic logs on the page it loads. You should say mission accomplished and we are done........ not yet this stupid page got something nasty in it. If i want to open our clients reports it opens in a new browser and this is something i can't change. So basically what happens if i click the report it opens in the standard user defined browser installed on my machine. This means i get a log in screen again cause my session is in the VB.net browser.
Let me show the code i use at moment that i use to auto log on. For some reasons i did cut out the URL's out of my code. (privacy, security etc.)

May 28, 2007I would really like to get some VB.net program code for still image capturing using a Webcam.I've searched the web for quite a while now but did not get any codes. Currently i have a code for capturing video. In that code an image can be captured, but only with 640 X 480 resolution (Maximum Video resolution for my web camera). The WM_CAP_DLG_VIDEOFORMAT dialog box only allows the resolution to be set up to 640 X 480.

View 1 RepliesCapturing Screenshots As A Windows Service?
Jul 29, 2009Basically I have created a windows service using VB 2008 where I am trying to capture screenshots periodically.
The timer is working fine and I have tested this.
The purpose of the service is to monitor the desktop over night when the user is logged off, by capturing screenshots and saving them to file. This is so admin can be alarmed about security breaches etc.
The problem is is that I have not found a way to capture desktop screenshots as a windows service (or otherwise) while the windows logon screen is active (i.e: when the user locks the computer). I have used google extensively but to no avail

Creating A Local User With The Option "User Must Change Password At Next Logon" Set
Oct 19, 2010I am currently creating a tool that can manage local user accounts on Windows-PCs. I am using the functions described on
this MSDN page ; and after some struggling, I got most of them to work.
Unluckily, I haven't found a way to set the option "User must change password at next logon" while creating a new user account. I use the
NetUserAdd -Function to create the new user. I set the level to 1 and supply a
USER_INFO_1 -Structure . This structure accepts flags, and the flag UF_PASSWORD_EXPIRED seems to be exactly what I want - but when I set it, the user can log on without changing the password first...
I'm developing on Windows 7 Ultimate 64-Bit using Visual Studio 2010 Express.
Here's my code:
#Region "Constants"
Public Const UF_PASSWORD_EXPIRED As Integer = &H800000
Public Const USER_PRIV_USER As Integer = 1

View 3 RepliesVS 2010 Generate Image Path From Unique Name, What To Do With Invalid Chars
Apr 15, 2010I'm creating a radio streaming application, which plays a live stream from various radio stations in a small 'gadget' like application.
The user can add his own custom radio stations, by supplying a Name, a StreamUrl and, optionally, an Image that represents a logo or something of that radio station.The logo will be drawn on the main form when that station is selected.
I need to be able to save these custom stations, and I think it makes sense to use an XML file, which could then look something like this
<CustomStations>
<Station>
<Name>Radio 1</Name>
[code]....
Before I added the support for images, this worked fine, how to store the images. I want the user to be able to select any image from his harddrive, but I don't want to force him to keep that image in the same location afterwards. So I can't rely on the path that he selected. Instead, I want to simply load the image from the path he selected, and then save it somewhere else.
I am storing the XML file in the common application data path which I think is a good place for the images too.The problem is, how to determine a name for the images? I will always have just one image per custom radio station, so it makes sense to me to simply have one Images folder that holds all images, with a unique name.I can see two solutions:
1. Generate a random filename for every image
2. Use the Name of the radio station as the image name
For option 1, I suppose I could just create a string of 16 random characters and call that the filename. The problem of course is that there is no guarantee that I will get a unique filename. Yes, the chances of generating the same name twice randomly are very tiny, but it's still possible, and I just don't like that. How can I ensure that my random filename is unique? I suppose I could always drop the whole thing in a While loop that continues when the new filename already exists, but there must be a better way... Is there nothing in the framework that allows me to generate a unique random filename, in a directory of my choice (so not in the Temp directory...)
I like option 2 much better. The Name of a radio station is unique (there can't be two stations with the same name), so I don't have to worry about filenames conflicting. The problem with this approach is that there are no restrictions on the name. There's nothing stopping the user from naming their custom station "Radio~/aij!""_.fe" or something like that, which is obviously not a valid filename... So, I will have to do 'something' to generate a valid filename from the station name. I could simply remove all non-valid path characters from the name, but then I am no longer guaranteed a unique filename... Suppose there's two stations, one called "Radio/1" and one "Radio1", then after removing the invalid "/" character, the names will be the same and so I will generate the same image path for both....
