When I declare a WIN32 API like this
Private Declare Function GetScrollPos Lib "user32" (ByVal hWnd As IntPtr, ByVal nBar As Integer) As Integer
I receive an error message by the compiler -
"User-defined type not defined"
Do you know what it means?
P.S. This is VB6

i think there is no primitive datatype named IntPtr invb6. u can use long instead of IntPtr in this function.
|
|
|
|
|
You may use (Byref hWnd As Long) instead.
|
|
|
|

This Declare is for VB.NET, not VB6. The VB6 equivilent would be:
Private Declare Function GetScrollPos Lib "user32" (ByVal hWnd As Long, ByVal nBar As Long) As Long

Consider using API Viewer or API Guide for determining API calls from whatever the language.

Hi guys,
I am writing a small VB.Net 2005 program that should connect to different databases at run time. I would like to include the windows/.net datasource configuration wizard in the system and get the connection string from the wizard control but I cant find control or way to achieve the goal, is it possible or maybe is there a workaround?
Thanks for you assistance.

Got the answer to my question
Add references of 2 assemblies, Microsoft.Data.ConnectionUI.dll and Microsoft.Data.ConnectionUI.Dialog.dll, located at C:\Program Files\Microsoft Visual Studio 8\Common7\IDE which by the way are not redistributable, then in code you have something like this...
Imports Microsoft.Data.ConnectionUI<br />
...<br />
<br />
...<br />
Dim myDataConnectionDialog As New DataConnectionDialog<br />
DataSource.AddStandardDataSources(myDataConnectionDialog)<br />
If DataConnectionDialog.Show(myDataConnectionDialog) = Windows.Forms.DialogResult.OK Then<br />
txtSourceConnection.Text = myDataConnectionDialog.ConnectionString<br />
End If
Thanks to all who cared to think about it

That is good information to know! I have hear of people distributing connection strings by reading it from text file, XML file, INI file or a DSN file (.udl). I have to try your way. Thanks for the update.

I have developed an application in vb and have tried two ways of connectivity with oracle but none of them helped me.
once using the ADODC and A MSHgrid
second using an ODBC driver..
the error it shows is
"Test connection failed because of an error in initializing provider.[microsoft][ODBC]driver for [oracle](oracle)"
or it says
"error in initializing provider. The error from oracle cannot be retrieved."
Kindly Help.

|

|

Which VB? VB6, VB.NET 2002, 2003, 2005, ...?? Which version?
|

The application is in vb and the connectivity is through oracle 9i.
Cannot connect using adodc" microsoft oledb provider for oracle"
the steps i follow are as below:
1. set the ado data control on form, click to set the properties of Adodc.
2. Choose build for conn str, microsoft ole db for oracle.
3. the next click asks for the server name, the user name and pwd.
4. testing connection after feeding "scott/tiger", gives error, it says "Connection fails.error while initializing provider, the error could not be recovered from oracle".
5. Even if i set the server name to oracle9i , it doesnt work giving the same error.

Google for ODP.NET to get your hands on the Oracle Data Provider for .NET.
What you're using requires that you have the Oracle Client installed. The ODP.NET library doesn't require this.

 Which property to use in order to ensure that atleast one option has been choosen before continuing to clicking a submit button?
Eg..
suppose i have a log in form, i have filled the userID, the password.Now i have a frame which has dept types as option buttons.No default value has been choosen. how do i ensure that atleast one option button is clicked before submitting the form.

What's the container holding the RadioButtons?? Is this a Windows Forms app or Web Forms??
I'm assuming this would be a Web Forms app, in which case, if you wanted this validated BEFORE the form is submitted, I believe you'd have to do the validation using client-side JavaScript code in the page.
I haven't done any ASP.NET development so I'm no expert. You might want to ask this in the ASP.NET forum for a second opinion.

i have developed it for a vb form.
it contains radiobuttons and no default has been choosen.
how do i validate now?
|
|
|
|

Well, there's something you're not telling me because if you put a bunch of RadioButtons in a container, the first one is always selected, automatically, even if your code sets its Checked value to False.
So I wondering what you did to get it to NOT be selected when you run your code.
But...
If (RadioButton1.Checked Or RadioButton2.Checked Or RadioButton3.Checked) Then
' Something got selected...
Else
' Something did NOT get selected
End If

I don't know how it is linked to Word but try the following:
Troubleshooting "RPC Server is Unavailable" in Windows
RESOLUTION
To resolve this issue, follow these steps: 1. Click Start, click Run, type the following line in the Open box, and then click OK:
net start rpcss
Test to see if this resolves the issue. If the issue still occurs, continue to the next step.
2. Click Start, point to Programs, point to Accessories,and then click Command Prompt.
3. At the command prompt, type ping servername, where servername is the server, NetBIOS, DNS, or GUID name that you want to test for connectivity.
If there is a connection issue with one of these computers, contact your network administrator to resolve the issue. If the issue still occurs, continue to the next step.
4. Use the Netdiag tool that is included in the Microsoft Windows Support Tools (included on the Windows CD-ROMs) to determine if the domain controller is working correctly. You can perform a network trace using the MSRPC, DNS, NBT, LDAP, or TCP protocols.
If there is an issue with the domain controller, contact your network administrator to resolve the issue. If the issue still occurs, continue to the next step.
5. Use the Netdom tool that is included in the Windows Support Tools to verify network trust relationships and reset or establish a connection to a server.

This is probably caused because your code didn't shutdown and free up the Word object when you closed your application the first time.

Great and all, but I don't he's running Word remotely over DCOM.
