You wouldn't normally deploy sql server with an application, you normally have sql server running on a dedicated windows server on the network and clients connect to it, otherwise you have no single database for the company - each user has their won database, which doesn't make sense.

There's no option. People generally deploy an Access DB if they can. Otherwise you need to deploy SQL Server Express, and code to create the database within it. This is a fair bit of work.

hello guys
thanks for your reply.
but after googling i found that there are some options why which we can do this if you look at this forum reply..
http://bytes.com/forum/thread142240.html[^]
you will fnd out that Dan Guzman replied that
"Depending on your requirements, you can include the scripts in a .Net
project as either content files or as embedded resources. You can then
include that project in your Setup and Deployment project. Your custom
action can read and execute the scripts from either the resource assembly or from the file system"
this seems gud but i don't know how to achieve this.
and what about this Article:

Basically it means you can deploy a program which creates the database. Which is what I was saying. The program still needs to run, and it need to find the DB, and run the scripts to create your tables, etc.
Access mdb files are easier.

i have a form that allows the usere to add 0 to 4 contact numbers.
If tphone4 = "" And tphone3 = "" And tphone2 = "" And tphone1.Length > 0 Then
p.fAddPhoneNumber(contactId, phone1, tphone1)
ElseIf tphone4 = "" And tphone3 = "" And tphone2.Length > 0 And tphone1.Length > 0 Then
p.fAddPhoneNumber(contactId, phone1, tphone1)
p.fAddPhoneNumber(contactId, phone2, tphone2)
ElseIf tphone4 = "" And tphone3.Length > 0 And tphone2.Length > 0 And tphone1.Length > 0 Then
p.fAddPhoneNumber(contactId, phone1, tphone1)
p.fAddPhoneNumber(contactId, phone2, tphone2)
p.fAddPhoneNumber(contactId, phone3, tphone3)
Else
p.fAddPhoneNumber(contactId, phone1, tphone1)
p.fAddPhoneNumber(contactId, phone2, tphone2)
p.fAddPhoneNumber(contactId, phone3, tphone3)
p.fAddPhoneNumber(contactId, phone4, tphone4)
End If
above is my code. I just want to add the phone number if the text box(es) and dropdown box(es) ONLY has a data in it. also my code does not look right, any suggestions guys?

Yes, it's obviously wrong. Assuming that the user can't enter text in just tphone4, for example, you should start by checking 4, and work your way down. Otherwise you only ever store the first number. A better approach is to build a list of numbers from the four textboxes, then work out how many you have.
The other option is to check each pair individually, without the elseif. So, each one that has a pair of values, is stored, that seems the simplest solution. Why would you store phone1 b/c phone4 has a value ?

what i did was this:
If IsNothing(phone1) Then
phone1 = ""
Else
If tphone1.Trim.Length > 0 And phone1.Trim.Length > 0 Then
p.fAddPhoneNumber(klayentAydi, phone1, tphone1)
End If
End If
If IsNothing(phone2) Then
phone2 = ""
Else
If tphone2.Trim.Length > 0 And phone2.Trim.Length > 0 Then
p.fAddPhoneNumber(klayentAydi, phone2, tphone2)
End If
End If
If IsNothing(phone3) Then
phone3 = ""
Else
If tphone3.Trim.Length > 0 And phone3.Trim.Length > 0 Then
p.fAddPhoneNumber(klayentAydi, phone3, tphone3)
End If
End If
If IsNothing(phone4) Then
phone4 = ""
Else
If tphone4.Trim.Length > 0 And phone4.Trim.Length > 0 Then
p.fAddPhoneNumber(klayentAydi, phone4, tphone4)
End If
End If
basically it one by one checks the controls if there is data then adds it.

hi
I M using Arraylist to store values. i want to find the most frequently occurring, or repetitive, value in an array (ie Mode of the array).
Please help.
thanks

You need to step through the array and count the objects. You shouldn't use ArrayList if you can help it ( i.e. unless you're in the .NET dark ages of 2002 or 2003 )

I m using dot net 2005.
I can use other alternative of array list.
What is the best way to find the most frequently occurring, or repetitive, value in an array with less complexity in program.
thanks 4 reply.

OK, then you should never use ArrayList. Use the generic collections.
List<T> has a number of methods you can use. You can use findall to figure out how many of each possible element appears in the list. You can use foreach to write a method that counts items ( by storing them in a dictionary I expect ), or you can just sort the list and then step through it ( counting then becomes trivial )

Hello,
You may use the Array concept for the same as .Net provides FindAll() method for it as well.
I would suggest you to go through the given links of MSDN.

I believe this should help you.

is there a way to display data into listview if the data is located in different tables in ms access? thanks
|
|
|
|

You can get the data from different location formulate in a string the way you want and then add the string...
Good luck

First, please read the post at the top of hte forum on how to ask questions. Everyone here wants help in VB.NET.
Yes, you need to write the SQL that selects the data you want to display from across the tables, by doing joins betwen the tables. If the tables are unrelated, then probably not.

Hi,
I am fairly new to VB.net and have been working with regular expressions recently. I was wondering how someone would call a static Regex from a compiled .DLL in an application? I have tried multiple ways to make the regex available from the .DLL, but no luck.
Any information would help.

Not sure what you mean, how is it in a dll ?

Hi
I am in the process of adding video capture functionallity with the use of the DirectShow API. My program has been written in VB.NET, but due to compatibility issues I have been writing code in C++ so that I can fully access the directshow api.
But I seem to have hit bit of a brickwall in attempting to integrate the code.
I thought it was possible to be able add the c++ project into the VB.NET project, and be able to make function calls from the VB.NET GUI interface with the C++ code. Is this possible?
Another option that I am now considering is exporting the c++ code as a DLL file and from there I can access the c++ as a library file?
Although I would prefer my first suggestion if this is possible?
Any suggestions would be greatly appreciated
Cheers

Yes, you use pinvoke for that, and yes, your C++ code needs to be in a dll. Or, you can make your code C++/CLI, then you can call it directly, but it still needs to be a dll

I am working with VB.Net 2005 looking at an Access 2003 database. When I run my Crystal Report (version 10.0.5.1279) I get a Database Login screen even though I don’t have passwords set at all in this datatbase. Can anyone tell me of a way to stop this from coming up?
Thanks in advance for all of you help.

I've had a similar issue and was only able to get around it with a rather complicated work around. It has to do with the database you designed the report with no longer being located in the same file structure as it was during design time...which is NEVER once you've deployed it and the report is being run on your client's machine.
I got past the issue by including an access database that contained the same table and field structures as I used during design of my crystal report. Then, before I set the report documents datasource or the crystal viewer's ReportSource property, I do the following:
'My schema database has been downloaded to the CurrentUserApplicationData folder via ClickOnce publish settings
Dim strSchemaPath As String = My.Computer.FileSystem.SpecialDirectories.CurrentUserApplicationData & System.IO.Path.DirectorySeparatorChar & "SchemaDB.mdb"
'This will set the login info to the schema DB, even though it has no passwords set, so the login screen will not display
cdReportDocument.DataSourceConnections.Item(0).SetConnection(strSchemaPath, "", False)
This workaround seems very silly, and requires the user to download a good sized file when they really shouldn't have to. But I've posted this question in several forums and no one has been able to help me with a better fix. If you find anything better please let me know.

I need to call NetAPI32 to get domain info on legacy workstations (IE: Win98, etc - DirectoryServices is not avail in 98).
I have the following code. The call to DsGetDcNameAWin5 doesn't error off, but the values are 0. I've tried changing the function declare to (using a pointer) as the last param with no success also:
Private Declare Function DsGetDcNameAWin5 Lib "netapi32.dll" Alias "DsGetDcNameA" (ByVal ComputerName As String, ByVal DomainName As String, ByRef DomainGuid As GUID, ByVal SiteName As String, ByVal Flags As Integer, ByRef lpDomainControllerInfo As IntPtr) As Integer
Could someone please show how to properly call and then extract the data from this .dll?
Sample code:
Private Const NO_ERROR As Short = 0

dci.DomainGuid.Initialize()
m_LastError = DsGetDcNameAWin5(strComputer, strDomain, dci.DomainGuid, vbNullString, m_Flags, lpBuffer)
If m_LastError <> NO_ERROR Then
GoTo ErrorHandler
End If
' Recover structure into one we can deal with in VB
'Call CopyMemory(dci, lpBuffer, Len(dci)) 'Doesn't compile
' Transfer contents to member structure.
m_DCI.DomainControllerName = PointerToStringA(dci.DomainControllerName)

I am currently studying computer in a local university in my country.
I am using Visual Basic 2008 to develop a program for a Windows computer(desktop) which only have one numeric keypad and does not have any standard keyboard.
I hope that when my program is running but Windows focus on other application, or when my program is running in inactive status, if the user press the '+' button (or other button set by me) for three times on the keypad with fast, Windows will switch to my program immediately.
How can I do that?

|

Set a keyboard hook[^] watching for the + key. When it is pressed start a timer. If the + key is pressed two more times before the timer event fires, show your form. Otherwise, do nothing.
