I want to use SendMessage to send a WM_UPDATEUISTATE message that I hope will show the focus rectangle on option buttons but I cannot find the constant values for the expected wParam values: UIS_CLEAR, UIS_INITIALIZE, UIS_SET, UISF_HIDEACCEL, UISF_HIDEFOCUS, UISF_ACTIVE.
I know that I can change a setting in the Control Panel (Display - Appearance - Effects) but I want to be able to control this programmatically.
Any ideas?

If I read this right, you just want to move the input focus to a button control. In VB.NET, that's easy:
controlName.Focus()
will set the focus to that control. BUT!! (There's always one of these!)
Long version:
A control cannot receive focus unless it is enabled, is visible, AND HAS A WINDOW HANDLE ASSIGNED TO IT! What this means is, you can only set the focus to the control AFTER it has actually been created and it's Message Loop is up and running.
Short version:
If you try and set the focus to a control in a Form's Load event, you must first Show() the form, THEN set the focus to the control. Otherwise it won't work.

Thanks for the reply, but no. What I want to do is tell Windows to show a focus rectangle around the text of a button that has input focus. By default in XP it does not. Also, I am using VB6, not .Net.
If you search MSDN for the WM_CHANGEUISTATE Message you'll see exactly what I'm talking about.
On the other hand, if you have .Net and you search your local help file for the UIS_ and UISF_ constants specified in this tread's header, might you be able to tell me the numeric value of these constants?
For example, I know that...
WM_CHANGEUISTATE = 295 (H&0127)
WM_UPDATEUISTATE = 296 (H&0128)
WM_QUERYUISTATE = 297 (H&0129)
...but I do not know the value for these other constants and they are not known by VB6 because it pre-dates their use in the operating system (beginning with Win2000).

OK. I think I understand what your trying to do now.
I found the constants in WinUser.h in the VC98\Include folder. Here is the copy/paste:
#define UIS_SET 1
#define UIS_CLEAR 2
#define UIS_INITIALIZE 3
#define UISF_HIDEFOCUS 0x1
#define UISF_HIDEACCEL 0x2
#if(_WIN32_WINNT >= 0x0501)
#define UISF_ACTIVE 0x4
#endif /* _WIN32_WINNT >= 0x0501 */
#endif /* _WIN32_WINNT >= 0x0500 */
#endif

Rage,
Thanks a bunch. That is exactly what I was looking for. Unfortunately, my winuser.h file does NOT include these constants and frankly I don't know why (VB6 Enterprise).
I'll track that issue down next.

Anyone know how to grant a user account "Logon As Service" rights through VB/VBScript?
I'm trying to pre-install a couple of services, and although I have managed to get the WMI scripts working to create and run the services as the account in question, I cannot figure out how to grant the account logon rights without having to revert to using the old NTRIGHTS util.
Target OS are XP/2K, they are running both Stand-alone, on NT Domain or an Active Directory.
Meanwhile ... i will have to wsshell ntrights :-<

I don't know how to do it off the top of my head, but the first question I have is: Is the .MSI being elevated to Admin level when it's run? Without this, you can't modify any use to Logon As Service.

My mistake, I should of mentioned that this is a straight VBS task (to be VBE'd later), and will be run from an Local Admin account.
Being a bit of a newbie to VB, I don't particually want to start fiddling with MSI just yet, it seems to be a bit OTT for the current purpose.
I have sort of found 2 ways around this. The first is to use NTRIGHTS.EXE but this means ensuring it's avaliable and that it can lookup the SID of the account that will require the rights. Unfotunatly this is not always possiable as it's a domian account that needs rights, and the service may need installing off-network (and NTRIGHTS won't take a SID as an argument).
The other method is to create on-the-fly a simplified Security Template then run "secedit /config /areas USER_RIGHTS ....." to apply the template. The only problem is if other user's have been given rights, the template wipes them out :-<

I haven't been able to find any scripting that will modify the Rights of a User Account. But, I can tell you that it is possible to do and it WILL require WMI to do it. Lucky for you W2K and XP both come with it native. 95/98/NT4 doesn't support WMI without first installing it seperately.
I'm still looking for a scripting solution...

Thanks for looking Rage, I can only assume you too are flummoxed!
I'm probably going to have to fall back on the security template method, assuming i can get 'secedit /export' to work so that I incorporate any previous security rights in the newly modified ones.

Im a newbie when it comes to .Net technologies. Right now I am developing an MDI application using VB.Net. So this is my first .NEt project.
first question:
... why is that when the child form is being closed using the control menu (control box), the next time i click the menu item that should make the child form show up again, it won't show anymore?....
here's the code behind the menu item:
Private Sub mnuRR_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuRR.Click
If RRChild Is Nothing Then
RRChild = New frmReceivingOrders(Me)
End If
RRChild.Show()
End Sub
* RRChild is the child form
* mnuRR is the menu item of the parent form
... tnx
.. here we go again.
|
|
|
|
|
This is how I've opened my MDI child forms.
Dim RRChild as New frmReceivingOrders
RRChild.MdiParent=Me
RRChild.Show()
Hope this helps
Cheers

We have a project that we recently split from one very large exe into 5 DLL projects. We have a greate deal of classes in each of the projects and we find that when we compile the program on a dev box there is a period shortly after the compile is completed where the app hangs for about 10-15 seconds.
Another of our guys had the same problem when at another site, where, once they had a large number of classes, VB was doing the same thing?
We have T30 and T40 IBM notebooks, so the processors and memory are fine, has anyone else experienced this and can anyone suggest anything?
Cheers,
Andy

My guess, if this is a .NET project, is that it is the initial JIT compilation that you are seeing.

Another possibility is that the IDE is re-registering the .DLLs. (REGSVR32)

I'm trying to consume a C# Web Service using VB6 and Soap Toolkit 3.
Everything works fine when I'm passing/returning simple data types such as strings and integers but I'm having trouble using complex data types.
The class I'm trying to pass is defined in my C# WS as
public class AlertMessage
{
public string AlertMessage;
public string AlertComment;
}
How do I treat this in VB and how do I pass it?
Currently, I have created an ActiveX DLL with a class AlertMessage as follows:
Private mAlertText As String
Private mAlertComment As String
Public Property Get AlertText() As String
AlertText = mAlertText
End Property
Public Property Let AlertText(ByVal Value As String)
mAlertText = Value
End Property
Public Property Get AlertComment() As String
AlertText = mAlertComment
End Property
Public Property Let AlertComment(ByVal Value As String)
mAlertComment = Value
End Property
When trying to pass an AlertMessage to the WS I get the following error:
SoapMapper: Saving SoapMapper alertMessage failed. No such interface supported.
When trying to return an AlertMessage from the WS I get a type mismatch error. My Soap response looks as follows:
<?xml version="1.0" encoding="utf-8" ?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<GetAlertMessageResponse xmlns="http://star-navigation.com/webservices/">
<GetAlertMessageResult>
<AlertText>Hello There</AlertText>
<AlertComment>My Comment</AlertComment>
</GetAlertMessageResult>
</GetAlertMessageResponse>
</soap:Body>
</soap:Envelope>
Can anyone help?
Thanks,
Cory

Am learning VB. I have not had the need until recently to install one of my apps on a machine that doesn't have VBruntime installed. Is there a way to include vbruntime in the install application so that it installs on the users machine at the same time as the application I have created?
Thanks,
Jim

Hi!
I have a problem with the center of the form in relating to the changing of the screen resolution and I would like to have aide. Please help!
In my application, I change the screen resolution to 800x600 when the app is started and will restore to the original state when quit. About the code of changing the screen resolution, it like the code in the sample of the www.AllAPI.net: http://www.mentalis.org/apilist/ChangeDisplaySettings.shtml
My problem is that if I change the screen resolution and then in my app, I use a procedure to center the form like this:
Sub centerForm(ByRef theForm As Form)
theForm.Left = (Screen.Width - theForm.ScaleWidth) / 2
theForm.Top = (Screen.Height - theForm.ScaleHeight) / 2
End Sub
but I always have a problem that the form nerver be centered correctly
I case I don't change the screen resolution, I don't have this problem
This is the thing that I would like to need you help
Thanks in advanced!
