Thanks Robert.
How can I code the initializtion succeeds?
Private Sub frmSlash_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim main As New frmMain
Dim slash As New frmSlash
slash.Show()
main.Hide()
'if the time > 2 second then ??how to code the condition??
'I want it to show up the main form after 2 second the slash form load
main.show()
slash.hide()
End Sub

Create a module and use this code. Make sure you set the module as the startup program
Imports System.Threading
Module startmod
Dim threadsplash As Thread
Dim frmsplash As Form
Public Sub main()
frmsplash = New Splash
With frmsplash
.Show()
.Refresh()
End With
threadsplash = New Thread(AddressOf hidesplash)
threadsplash.Start()
Dim Form1 As New Form1
Application.Run(Form1)
End Sub
Private Sub hidesplash()
frmsplash.Opacity = 1
frmsplash.Refresh()
threadsplash.Sleep(15)
frmsplash.Opacity = 0.9
frmsplash.Refresh()
threadsplash.Sleep(15)
frmsplash.Opacity = 0.8
frmsplash.Refresh()
threadsplash.Sleep(15)
frmsplash.Opacity = 0.7
frmsplash.Refresh()
threadsplash.Sleep(15)
frmsplash.Opacity = 0.6
frmsplash.Refresh()
threadsplash.Sleep(15)
frmsplash.Opacity = 0.5
frmsplash.Refresh()
threadsplash.Sleep(15)
frmsplash.Opacity = 0.4
frmsplash.Refresh()
threadsplash.Sleep(15)
frmsplash.Opacity = 0.3
frmsplash.Refresh()
threadsplash.Sleep(15)
frmsplash.Refresh()
frmsplash.Close()
End Sub
End Module

A little simpler alternative is:
Sub Main:
Module modMain
Public Sub Main()
Dim frmMain As New frmMDIMain()
Dim frmSplash As New SplashScreen()
Dim fStart As Boolean = False
'Show the splash screen
frmSplash.Show()
'Run start up code in splash screen
fStart = frmSplash.RunInitialization
'Close the splash screen
frmSplash.Close()
'If startup was successful launch frmMain
If fStart Then
Application.Run(frmMain)
End If
End Sub
End Module
SplashScreen code
-------------------------------------------------------------------------------------------
Public Class SplashScreen
Inherits System.Windows.Forms.Form
#Region " Windows Form Designer generated code "
...
#End Region
Private m_fTimeout As Boolean
Public Function RunInitialization() As Boolean
'Enable wait timer
Me.tmrWait.Enabled = True
Dim fStart As Boolean = False
'Run your main Startup code wrapper function here
fStart = RunMyAppStartup()
'Process messages in wait loop until wait timer expires
'Don't care about performance hit of DoEvents for wait timer
While Not m_fTimeout
Application.DoEvents()
End While
'Return value of startup success to Sub Main()
Return fStart
End Function
Private Function RunMyAppStartup() As Boolean
'Your application startup function calls go here
'Just return True for example
Return True
End Function
Private Sub tmrWait_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrWait.Tick
Me.tmrWait.Enabled = False
'Set timeout flag to True
m_fTimeout = True
End Sub
Private Sub InitializeControls()
Me.lblVersion.Text = "Version: " & CURRENT_VERSION
Me.lblTitle.Text = Application.ProductName
End Sub
End Class

Ive been having this problem with a access database im writing. Im trying to use a form to query data from a table based off whats in a certain box on the form and putting it into word using mailmerge. Ive got the code down for the query and it works but heres the code im having trouble with.
Private Sub Command2_Click()
Dim objWord As Word.Document
Set objWord = GetObject("C:\QA\RB.doc", "Word.Document")
objWord.Application.Visible = True
objWord.MailMerge.OpenDataSource _
Name:="C:\QA\QA.mdb", _
LinkToSource:=True, _
Connection:="QUERY test", _
SQLStatement:="SELECT * FROM test"
objWord.MailMerge.Execute
End Sub
The problem is that it opens the database again and i dont want it to i want it to get the information from the currently open database
Thanks
Nathan

It's doing exactly what you told it to. The OpenDataSource method you called will open the database using it's own connection, not yours. This should be no surprise considering you never gave (or even get the opportunity) to pass in an externally generated connection object.

I know that but how could i rewrite it to not do that. Im still kinda learning access VB.
Thanks for any help.
|
|

|

That's just it, you can't! There is no method provided by the MailMerge object that will allow you to supply a previously prepared connection object. MailMerge will always create and use it's own connection.
Why is this an issue anyway?

Well what im trying to do is:
I need to create a mutipage report with different things on each page. So i figured i would use mailmerge but then i also need to be able to have the user pull a record of choice to be displayed in word for this mail merge. Which i have been able to accomplish the only problem was with opening the database and pulling the data i need from a form. Thanks for the help at least now i know its not possible. Do you have any idea on what would be a way to do this without mailmerge. Thanks again for your time.

You have several options.
First, you can dynamically create a Query that MailMerge can execute to get the data it needs. Either plug the SQL statement directly into the MailMerge.OpenDataSource method, or build the query in Access and have MailMerge run that Query to get the data. You'll probably have to modify the query in Access first before you tell MailMerge to execute the query.
Next, use the appropriate tools for the job. MailMerge gets it's name from Mailing List. It merges a list of names and address into form letters and such. Though it can do more than just this, reporting is not it's forte. I would suggest using the Reporting features built into Access first.
Lastly, use an actualy reporting package, such a Crystal Reports.

Does anyone know how to extract the amount of physical memory installed on a machine via registry using VB.net? The example below was written in KIX but I'm unable to replicate in VB.net. I'm having issues reading the data type REG_FULL_RESOURCE_DESCRIPTOR.

Since you're using VB.NET, why not just skip the complicated math junk coming out of the Registry and get the data you want using WMI?

I'm trying to gather hardware info from Win2k, WinXP and WinNT machines (which do not have WMI installed.) Is there another method other than WMI for NT machines?

Once the .NET Framework is installed on the machine, that's no longer a problem.
Or is there something else you're not telling us?

???? .NET Framework is not installed on the NT machines. I'm querying these machines remotely.

...How did I know...
The other problem that your going to run into is the possibility that the RemoteRegistry service is not running on these machines. Or that the machine is not patched up with the latest service pack, causing wierd problems in just connecting to the services that you want.
I ran into the same problems myself, doing exactly what your doing.
But, I guess it's back to the parsing problem you were having.
What are you using to get at the Registry? Is it the Registry class? Since the Registry class interprets the data you send to it or is retrieved from the Registry, is the data even being returned correctly? Are you getting an array of bytes?

Assuming the RemoteRegistry service is running, the problem is, I dont know how to read/extract the data type REG_FULL_RESOURCE_DESCRIPTOR from HKEY_LOCAL_MACHINE\HARDWARE\RESOURCEMAP\System Resources\Physical Memory[.Translated]
Thanks

Yeah, I tried a little sample code and found that none of the current Registry classes or providers will read the thing. You'll have to P/Invoke the Win32 Registry functions to get this to work. There's little to no documentation on this RegType so it'll take some trial-and-error to figure it out.

I'm not sure why you want it from the registry but this may be of intrest:

Thanks but not what I'm looking for. I'm gathering hardware info from win2k, winxp and winNT machines. WinNT does not have WMI installed so I cannot use a wmi query.
Thanks anyway

|
|
|

"WinNT does not have WMI installed so I cannot use a wmi query"
Ok, but the one in the link I sent you isn't WMI it is the GlobalMemoryStatus API.
But it was just a thought.

|
|

He's polling for this information from a remote machine, so using the API's won't work.
