what i would do is use the FindWindow API (not sure .. but the API which accepts a string title of a window and returns a handle to the same).
if a valid handle was returned .. then DONT LAUNCH..
else..
mail me if u would like me to make a small snippet for ya !

I want to be able to call a function in a DLL at run-time, without first putting a DECLARE in my VB program at design-time. Any sneaky ideas? Here's a little head-start that maybe someone out there can help me with. I can call the LoadLibrary API function to get a handle to the DLL I want. Then, with this handle and the name of the function I want, I can call the GetProcAddress API to get the address of the function. In C++, I could simply jump to this address, but how can I call this function by its address in Visual Basic? Anyone know?
THANKS!

Hi,
I really do not think that this can be done simply with a code snipit. You will have to use a ActiveX control, this could get a little expensive.
Check out this site, it may have a listing of such controls:

Hardware is another consideration
Good luck,

IK,
Well to tell you the truth I've been wanting to write one of theese for myself for quite some time. Heres what you do:
- Prevent escape keystrokes (CTRL ALT DEL, ALT F4 ect)
- Size the window to full screen and prevent the user from using the start menu
-have the program start at system startup to prevent the computer from being restarted in order to access the system
It's that simple!
As for hiding the start menu/taskbar, thats as far as I got, I dont know how to do that.
Maby I could send you someting by e-mail if anyone else hasen't already done this in VB.

I know how to create an instance of activeX control using CreateObject, but this doesn't exactly display the visual control on the form. It seems like it only creates an object instance of it. How do I make it so that i can switch between activex *visual* controls dynamically on a form?
thanks,
|

Loading ActiveX controls on form dynamically at runtime is not that easy.
One way is to declare an object variable. but you cannot handle events for the controls.
Other way is to declare a variable as VBControlExtender.
u can declare this variables with events.
The procedure to use this VBControlExtender:
'place the code in form_load or form_initialize event <br />
<br />
Dim WithEvents MyCtrl As VBControlExtender 'declaration<br />
<br />
Licenses.Add "MyCombo.MCombo" 'Add the licence of the control class to the project<br />
<br />
'Add the control to the form which is the parent to the control<br />
Set MyCtrl = Me.Controls.Add("MyCombo.MCombo", "MyCtrl", Me)<br />
'Set the position of the control and make it visible<br />
With MyCtrl<br />
.Top = 100<br />
.Width = 100<br />
.Height = 315<br />
.Left = 100<br />
.Visible = True<br />
End With
Click event of the control can implemented in this way:
Private Sub MyCtrl_ObjectEvent(Info as EventInfo)<br />
'This Info parameter consists of event name and the parameters of the event.<br />
If Info.Name = "Click" then<br />
'do your code<br />
End If<br />
End Sub
that's all
Regards,
Ravi.

Hello everyone,
I am currently working on a project which calls for the creation of ActiveX User Controls. The controls would need to be able to implement a vertical or horizontal slider that would divide 2 user panes (just like File Explorer or Outlook). I could implement this in a standard VB project but in a control it seems a bit difficult. Moreover, I have three different conditions to consider as well.
1. A splitter control that is activated only during design-time.
2. A splitter control that is activated only during run-time.
3. A splitter control that is activated both during design-time and run-time.
I would appreciate any form of help on this topic. I would appreciate reference source codes of any implementation of this sort.
Thanks and regards.

dear reader,
can i add a new button in MS Word - other than the bulit-in buttons and add my functionality to it?
or can i change the functionality of a buit-in button?
if yes, could u pls. let me know how?
it's urgent.
thanx.

You didn't say what version of Word you're using, but in general, the answer to your question is YES! The best approach is to write a COM Add-In in Visual Basic and then ensure that the add-in loads on startup in Word. Within the code of the add-in, you'll want to hook into the CommandBars collection. Within this collection, you can access existing buttons, or you can create your own using the add method. Then, you'll create an event sink, you that you get access the the click event of the new (or existing) button. There a lot of good documentation about this on MSDN Online.
Hope this helps!

I have inserted a thumbnail preview control to my form.
I then call it's function displayFile() with a string that points to a local html file (not a URL, of course). I get a FALSE result from that function, no matter what I do.
The files I try to preview are ok when viewed in a browser, and when I am looking at their preview in Web View mode (inside the folder), it works as well, just not in my application.
What gives? Can anyone give me some insight into this strange component?
Thanks,
Aric.

Is this the Kodak Image thumbnail control, or another one?
Cheers,
Frank
|
|
|
|

Nope. Not the kodak thumbnail. I'm talking about the one in the dll webvw.dll (under system32).
I have gotten answer from Microsoft that this control is not for public usage... this sucks! it only works when being accesses by a specific control (being Internet Explorer).
I hope the MS split will fix such political issues in the components. I hate politics and dirty manipulations.
Aric.
