Hi to All,
Here is an another problem of mine.I am using vb.net2005.
I want to maximize the form so that user can not access the taskBar. I got some code,to hide the windows task bar. But when I run another process(say calculator) from my application, the taskbar reappears.
So I was wondering if any method or property is there to maximize the form so that, the form comes top of the task bar itself....
Please suggest a way
Thanks in advance

hi to all
Could anyone please tell me how to block certain drives to be accessed while looking for sub directories and files.
(All I want is to give an environment to the user so that HE CAN LOOK FOR FILES IN A DIRECORY, WHICH ALSO MAY HAVE SUBDIRECTORIES). The tool I am using is dirListBox in vb.net2005.
But my problem is that user can go to all the files and directories in the computer. (i WANT HIIM TO ACCESS THE FILES AND FOLDER OF A SPECIFIED DIRECTORY ONLY, SAY INSIDE C:\AA)..
NOW HOW TO FILTER THE DIRLISTBOX,?
please advice me if any other method is there for the same...(not necessary to be the DirListBox control)
THNAKS IN ADVANCE

There is no "DirListBox" in VB.NET. Are you talking about the OpenFileDialog or are you using the old DirListBox from the VB6 days?? The old DirListBox could not be filtered or limited to a group of folders.

thanks for the reply
ok can openfiledialog be make to show or start from a particular directory? User shouldnot be able to view others

Have a read through the members of OpenFileDialog, in the MSDN documentation. It should be fairly easy to find the correct solution.

The OpenFileDialog class is a wrapper to call the Win32 function OpenFile (? I can't remember which the function name exactly!). Win32 displays the dialog, not the .NET class OpenFileDialog.
OpenFileDialog is also a sealed (NotInheritable) class, so you can't really modify it at all. You can't even get the window handle to the dialog and start throwing messages at it since your code stops running when you call the dialogs .ShowDialog method.
Your going to have to write your own dialog to support this. It would just be a simple Form with a TreeView for a directory browser, and a ListView for files in the currently selected directory. Oh, and of course, a couple of buttons for Open and Cancel.

Hello every one,
I am having a VB.net 2005 application.
Earlier we had designed the application with a fixed window size, now we had implemented TableLayoutPanel in it to make it full screen.
After the implementation I made Windowstate as maximized for the forms. Now I am encountering some thing strange,
On formName.show first the form1_activate is executed instead of form1_load.
(Openinf form1 from form)
Once I reverted back “Windowstate to Normal” the execution sequence comes back to normal (Lode and then execute)
Can any one plz help me out with it...
Regards
Nishkarsh

You can't change the firing order of events, so the only thing you can do is change your code to handle both cases. I have to question what code you're putting into the Activate event handler, since this event fires every time the form gets focus for any reason, not just when the form first appears. Normally, you'd use this event to update the forms controls with new data when the form regains the focus.

Thanks Dave for the input. My exact question is that after making The window state to full screen in designer, why form activate is executed before load.
I had done a way around now that i change the window state to full screen at the end of form load. But want to know why way it happening

Can anyone help to generate a PRINT PREVIEW of a sales report from SQL 2000 database and group by INVOICE NO. With INVOICE SUB TOTALS. THANK YOU
|
|
|
|
|
Through VB.NET, or do you just want a report?
If the latter is the case, then simply install Microsoft Access. Link the SQL2000 tables to the Access-database, open up the report-wizard and enjoy

to generate a PRINT PREVIEW
You'll have to decide what you're going to use for a reporting-engine, or what you want to use to display this print-preview in. There's Crystal Reports, there's some integrated components from Microsoft or you can simply spit out a HTML-document.
of a sales report from SQL 2000 database and group by INVOICE NO. With INVOICE SUB TOTALS
That's a relative simple SQL-query, with a grouping and an order-by
Have you worked with VB.NET before?

Not crystal report but print document in vb.Net. and also i'll need each invoice total to be printed eg.
INV_NO QTY ITEM UNIT_COST AMT_PAID
001----- 2 --- Bag -- 20.00 ---- 40.00
001 ---- 6 --- Purse - 0.20 ---- 1.20
---------sub total(invoice 001)- 41.20
______
002 ---- 10 - Bag --- 20.00 ---- 200.00
---------sub total(invoice 002)- 41.20
______
GRAND TOTAL -------------------- 241.20
______
This is just to give you an idea
THANK YOU

When i add crystalreport9 to vb6.0 in Windows vista,Appcrash problem occured. What is the solution for this. Can u help me....
|

VB6 is a POS and is no longer supported
Crystal Reports is a POS and should be shot
Vista is a POS and we are moving to Weven
I think you have absolutely no chance of getting a sensible answer with all the POS you are using.
I suggest you move to VB.net NOW, do not commit any more resources to the VB6 POS.

Crystal Reports 9, as far as I can find, is not supported on Vista. Crystal Reports XI is supported.

hi all,
i am simply copy a file from one computer to other.i use following command
File.Copy(BakFileName, "\\" & mdChecking.PublicServerName & "\" & shellCommand.Trim.Replace(":", ""), True) 'mdChecking.PublicServerName is computer name.
above code works well when i copy file from XP to XP, VISTA to XP but fail when i copy from XP to VISTA and give error "Login Failure:unknown user name or bad password"
Please suggest how can i resolve this error?

And can you copy files using Explorer or other file manager software?

It would appear that your code is building an invalid UNC path, or a path that doesn't exist. Move the code that builds the path to its own variable so you can see what it's building, then you can troubleshoot it better.
Dim destinationPath As String = String.Format("\\{0}\{1}", mdChecking.PublicServerName, shellCommand.Trim.Replace(":", ""))
File.Copy(BakFileName, destinationPath, True)
Now, the other part of the problem is are these two machines working in a Workgroup in an Active Directory??
If Workgroup, you've got problems. Each machine matintains its own list of user accounts and does NOT trust the accounts of another machine.
If in Active Directory, then is each machine in the same Domain?? Each machine in the domain will use and trust a central list of user accounts.

How can I receive a normal phone call using line H.323? I've done everything included in the code samples, successfully (Dim objTAPI As New TAPI3Lib.TAPI, objTAPI.Initialize(), mobjTAPI.EventFilter = ..., etc.); however, the events are not fired when there is an incomming call. Please help me.

I've never used TAPI or the TAPI library, so I really can't answer your question.
But, the first thing anyone is going to ask is do you have a TAPI 3.0 compliant modem and drivers and are the drivers installed for it??
Beyond that, I've got no answers.

Hi,
Using TAPI is bit tricky and hard , but there a wrappers available
over it , one of such wrapper is available at the following site
http://www.codeplex.com/C4FDevKit[^]
Its an open source wrapper , you can also find information regarding it on
http://www.microsoft.com/express/samples/c4fdevkit/default.aspx[^]
You can use it to recive phone call or to build Instant Voice response System kind of stuff
It has worked for me , hope you would also find it helpful
-Regards
