hi,
I have created two applications using vb.net.
One acts as server and other as client. To have communication between these two, in server application i m using winsock control and in client application i am using socket class. when i sends data from client application, server connection dies while reading data second time and raises the exception and flashes error "An existing connection was forcibly closed by the remote host".
Please tell at the earliest how this error can be resolved.
how this connection can be kept alive.
Thanks.

Please don't repost, it's just annoying. Edit your old post if you want to add something, as it seems you did.

Hi,
I need a VBscript to set the user profile. As my current system settings will hold the defaults. The Changes i made from the CMD promt will be lost once i logoff and logon.(I think the Machine settings overrides the User profile)
Please hel give resloution in this regard. i am not VB Script Programmer only i need to do this task by script
to avoid daily setting of user profile.

ListView's only select entire rows, not cells. Use a FlexGrid instead if you want the ability to select any row or cell in a row.

Authenticating what ? I assume input ? In which case, you have things like masked text controls, you have validators, and you can write your own code to validate input any way you like.

There's nothing built in, no. You'd have to build your own permissions system, and it's not as secure as a web app, because anyone who has your exe can decompile it and remove the permissions checks. They are also more likely to have access to the database that tracks who has permissions to what.

I'm working on a vb6 project with Crystal Report 8.5 . I want to call a stored procedure from my app. After getting the result from my database, how to print it out directly without showing in the Crystal Report fist.
Thanks

you can go with, Using Server-Side ReportDocument.PrintToPrinter Method or by Client Side JavaScript: window.Print.
Using Server-Side ReportDocument.PrintToPrinter Method:
The Syntax is :
Report.PrintToPrinter(<copies as="" int="">, <collated as="" true="" false="">, <startpage as="" int="">, <endpage as="" int="">)
Client Side JavaScript: window.Print:
The Syntax is :
function PrintWindow(){
if (navigator.appName == "Microsoft Internet Explorer") {
var PrintCommand = '< O B J E C T ID="PrintCommandObject" WIDTH=0 HEIGHT=0 ';
PrintCommand += 'CLASSID="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2">';
document.body.insertAdjacentHTML('beforeEnd', PrintCommand);
PrintCommandObject.ExecWB(6, -1); PrintCommandObject.outerHTML = ""; }
else { window.print();} }
Hope this will Help you.

Yes, it sounds like you shouldn't be attempting this task at this stage, you should learn some core stuff first.
You create a combo box, and each item has a value property, set that to the Id of the department whose name it shows. Catch the selected index changed event. Grab that Id, stuff it into a proc that returns the data for that department and databind the returned table to your grid.
