My aim is to adjust (Birghtness, contrast, gamma, HZ, red, green,blue) values of video. I am able to get the pictures from a web cam but I want to be able to adjust these values also. If you have an sample or any link, please let me know. Thanks Re: How can I adjust some attributes of a video? Dave Kreskowiak13-Mar-06 10:30 Dave Kreskowiak 13-Mar-06 10:30  How you'd do this would depend heavily on what you're using to get the video stream and what you're using to display it. Each library is going to have, if supported, it's own methods for doing this.

Re: Database Connections using VB.Net 2005 JUNEYT13-Mar-06 2:15 JUNEYT 13-Mar-06 2:15  I got the same problem with 2005 and decided to use a connection string manually and then the problem has been solved... Use a connection string variable as shown below: Public ConnStr As String = "Provider=Microsoft.jet.OleDB.4.0;Data source=" & Application.StartupPath & "\Database\lyrics.mdb;Jet OLEDB:Database Password=111111;" Re: Database Connections using VB.Net 2005 Dave Kreskowiak13-Mar-06 7:27 Dave Kreskowiak 13-Mar-06 7:27  The string you provided is for an Access database, not SQL Server 2005.

It was my out of attention. anyway. He can rich the information at www.connectionstrings.org or .com Re: Database Connections using VB.Net 2005 Dave Kreskowiak13-Mar-06 7:36 Dave Kreskowiak 13-Mar-06 7:36  SQL Server 2005 has a tool called the SQL Server 2005 Surface Area Configuration tool. You'll find it under Start/Programs/SQL Server 2005/Configuration Tools. Start that, then click on Surface Area Configuration for Services and Connections. In the left side navigation pane, click on Remote Connections. I think you can figure it out from there. As for the connection string, a basic string using standard security would look something like: Dim connStr As String = "Data Source=serverName;Initial Catalog=databaseName;User Id=userId;Password=password" You can find more on connection strings at http://www.connectionstrings.com[^].

Re: array in vb.net JUNEYT13-Mar-06 2:17 JUNEYT 13-Mar-06 2:17  No you don't have to.

Thanx.. -- modified at 7:11 Monday 13th March, 2006 Re: question about tabs Dave Kreskowiak13-Mar-06 6:24 Dave Kreskowiak 13-Mar-06 6:24  That "write_cursor" as you call it is actually referred to as the Insertion Point, or I-beam. All you have to do is handle the KeyPress event of the first 5 textboxes and check the length of the text in that TextBox. If it's 5 characters, call the Focus method of the next TextBox in line.

Why? Because that's the only place to put them. You don't actually insert between two records, you insert them into the dataset. The database engine doesn't care in what order the records are in the table itself. If you care about what order the records appear in the table, then you're either not using correct to do what you want, or you're using the wrong object to store the table. Which ever is up to you. You haven't supplied enouogh information about your project to point you in any useful direction.

I have alreayd use background color as transparent in the image but it still like that...? any one know how to solve it? Re: how to make image transparent? JUNEYT13-Mar-06 2:11 JUNEYT 13-Mar-06 2:11  Transparency is quite bit annoying but that is how I solved the problem. First, the image which will use transprancey should be saved with alpha transparency. And then use panel and place the background picture as a panel's bakground picture. And then place the image inside the panel, it won't look square any more and transparenct will take place... Do not forget when save the image do not use index transparency but alpha channel transparency. Re: how to make image transparent? campbells13-Mar-06 4:07 campbells 13-Mar-06 4:07  is it in any format will work ? like gif,jpg... r u using photoshop to edit ur image? cause i cant found any in ACD editor and flash... anyway i only see the selection on background content as transparent only... wher eu set the alpha thing? Re: how to make image transparent? campbells13-Mar-06 5:13 campbells 13-Mar-06 5:13  have u try not to use the panel? i dont think it work for me after i put it in the panel casue i cant call the image to move even cant display it also image1.Visible = true Re: how to make image transparent? JUNEYT13-Mar-06 6:13 JUNEYT 13-Mar-06 6:13  It doesn't matter, you will able to move your image inside the panel. The image format should be gif to support transparency otherwise you should go with index transparency which brings some other issues to calculate in the code. creating a Dating Website uglyeyes13-Mar-06 0:14 uglyeyes 13-Mar-06 0:14  Hi all, I am learning to create a dating website. i am using sql server 2000 and visual studio.net 1.1 I want to create a robust website so that system dont crash or anything. i dont know how to create a good database design. every time i create a tables i happen to modify it i dont know. is there any free source code for complete dating site. i dont want to purchase or anything coz i am in learning stage. i actually found one but it is not created in Visual studio framework so it doesnt have aspx, aspx.vb and resx file and it uses mysql. is there anyway i can just seperate the coding into aspx, aspx.vb and resx. please help thanks Robin Re: creating a Dating Website Duan Yu13-Mar-06 0:33 Duan Yu 13-Mar-06 0:33  That's too hard, harder than actually getting a date! Re: creating a Dating Website Dave Kreskowiak13-Mar-06 6:12 Dave Kreskowiak 13-Mar-06 6:12  I seriously doubt you'll find the source for any dating website. You'd be better off looking for other projects and applying what you learn from those projects to your own. Try looking on http://www.asp.net[^]. RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome How to write code for checking the evaluation versiion of a software. Hari Prasad Karnam13-Mar-06 0:08 Hari Prasad Karnam 13-Mar-06 0:08  Hi, I am using vb.net 2003 in XP. I 've developed a project in vb.net. I would like to provide an evaluation version for the same. The software's evaluation period is set as 30 days. I did this in the following way : ---------------------------------------------------------------------------- Dim strDate As String strDate = GetSetting(VB6.GetEXEName(), "Startup", "TimeStamp") If DateDiff(Microsoft.VisualBasic.DateInterval.Day, CDate(strDate), Now) > 30 Or DateDiff(Microsoft.VisualBasic.DateInterval.Day, CDate(strDate), Now) < 0 Then Msgbox "Your Evaluation version has expired. Please register to continue" end End if ---------------------------------------------------------------------------- Above code works well and checks for the evaluation period. But if the user keeps on using the date between the trial period version (i.e., any date within the 30 days), he can still use the software for any number of days. Can any one please advice me how to prevent this. Is there any other way for this. Thanks in advance, Hari Prasad. Software Engineer. Hari Prasad... Re: How to write code for checking the evaluation versiion of a software. gnjunge13-Mar-06 1:22 gnjunge 13-Mar-06 1:22  There is no reall easy way in preventing this. you can do a number of things: 1) Every time user opens program write current datetime to some store. And then check the store if the previous date is before the current date, if not the user changed the system date and you can block the program. But this still leaves space for screwing around. 2) Have some window service running that checks all the time the date and checks if the date is set back. It's a big deal, and who wants to add a windows service for this. 3) Have ur program connnect to some timeserver on the internet. Very secure but maybe the user doesn't have internet or blocks ur program from accessing the internet. These are just some ideas. But there is no 100% good method.
