You cannot talk to someone through a modem as if it were a phone. Not unless the modem you ahve specifically has this capability, which I seriously doubt. After the modem dials the phone number, you have to pickup the phone!

hi
maybe you can help me:
i want to make a password to be seen.
i want to replace these ***** with letters.
thanks

Are you trying to hack an application? If you are you won't find any help here. If you are develping some code and aren't sure there is a passwordChar field if you set it to 0 then the * go away. You would have to re-compile the app then the password should be visible.

I need to create browser compatability applications. And i need to disable forward and backward buttons. Is there any solution for this?

That depends on what you mean by a "browser compatability applications". What is this app supposed to do?
Disabling the buttons has to be done upon the creation of a new browser window. You cannot just disable the buttons on the currently open window.
These questions are better asked in the Web Development or ASP.NET Forums. Nothing in this question has anything to do with VB.NET.

You can write virtually any SQL you like in the SqlCommand. So long as you have the rights to create the tables you can doing by passing the relevant commands through to the database.

Hello!!! I'm currently modifying a program VB .net using SQL Server 2000. The problem is: How can i store a picture to the database. Through browsing the JPEG file and automatically view in picturebox, but i cant save it directly to the database. Is anybody help me. Is there any idea regarding this matter.

Convert the source image stored by the PictureBox to a byte array, then store it in an image column in the database (you're going to need a parameterised query for that, unless you fancy converting the raw bytes to hex).
To get the picture out again, you will get a column which is a byte array. You can then convert that into a Bitmap which you can assign to your PictureBox.

Hi all,
I am using MS ACCESS database for my applicaion, in that i have an field to store system time and it's datatype is datetime.
When i store an record it stores correctly like this 4:24:16 PM. But whn i retrive the record in my application, the data retrived as 12/30/1899 12:00:00 AM.
My question is I want to compare this time with my current system time, for this i want to remove the date. I used convert() function, but this supports only sql not in MS ACCESS.
Plz any one kindly help me.
Thanks in advance

More of a discussion topic than a question. Thought of posting this in the lounge but decided to save myself from getting flamed
I got this[^] (as I'm sure most of you have as well) with the regular MSDN Flash newsletter & was a bit puzzled by the idea of implicitly typed local variables. It looks like an interesting idea but to my mind it may be opening a whole huge door for bugs. Although this kind of type inference saves a few key strokes & has advantages in preventing late binding is it really worth it? I dunno.
The rest of the article is pretty cool & I'm looking forward to playing with some of the features but I can't seem to wrap my head around this type inference thing (in that I think it'll allow newbies to create software of a poorer quality).
Am I wrong? Why am I wrong?

It is still strongly typed. If you initially create the variable as an integer, you cannot later store a string in there - the compiler won't let you. The scope is limited to the local method. Also, the benefit is more in being able to store anonymous types than anything else. After all, what would you define a variable as for an anonymous type?

I need to create a light weight Questionpaper Application in .Net, which a user can download from web.
After installation, the application should contact my webserver to fetch questions and display to the user and at the end of
the test, all the user responses need to be saved to my database online. Can someone advise what .NET technology I should
use to get this accomplished?

One post is enough.
you can try with the Asp.Net technology.
For more details log on to Asp.Net[^]

What you are describing is a Windows application as client that connects to a server application. I would suggest that you instead make a web application so that you use a browser as client. That way the user doesn't have to install anything, .NET framework is not required on the client, and the client doesn't even have to use Windows.

BTW please use same thread for the discussion it is just waste to create a new thread for the discussion of the same problem.
