This in not the method used by other applications with the same capabilities. The methods mentioned in my previous post are the ones used by professional applications simply because those methods are fool proof, easily maintainable, and above all else, supportable.
The target app would have to poll this file on a seperate thread so the user interface would respond. A feature that would be rarely used in the real world, but code would be running for it constantly.
This Start.exe would also have to poll the Process list, every time it was launched, to see if it's target app is running.
While it would work, with a couple holes in it, it's a messy solution...

If anyone is interested, this is a link to a document at Microsoft's Patterns and Practices - Improving .NET Application Performance and Scalability[^].
The document is a HUGE guide (about 1,120 pages) full of tips, samples, howto's, and checklists for improving the performance of your code using ASP.NET, ADO.NET, Web Services, ... This doc isn't just for professional coders either. The Noobies can get a bunch of information out of it too. Just reading Chapter 12 on 'Improving ADO.NET Performance' can answer a bunch of the recurring questions on the forums.

How can I change the layout of the keyboard dynamically(e.g from English character to French) in VB .Net
|
|
|
|
|
It can be done, but is not a recommended practice...
Your app can set it's own Keyboard Layout (seperate from the systems) using the ActivateKeyboardLayout, LoadKeyboardLayout, GetKeyboardLayoutList, GetKeyboardLayoutName, and UnloadKeyboardLayout Win32 API functions. The functions will have to be P/Invoked from user32.dll. The constants and structures used be these functions can be found in winuser.h.
Docs on all this stuff start here[^] on MSDN.
[EDIT]
Oh! There is nothing in the .NET BCL that can do this. You must use the Win32 API functions...

The registry isn't a recommended way of saving data in .NET, but all the information you need on reading/writing the registry is part of the namespace/class Microsoft.Win32.Registry.
If you do a search on MSDN for that term, you should find some VB.NET examples.

Combobox and remaining values of a Table on a DataGrid????????? I fail to see how the ComboBox fits in with the Table...
Are you binding the ComboBox and DatGrid to a DataTable? I don't get why you would pick a record from a table to display in a ComboBox, and then display only the remaining records in a DataGrid.

Hi,
I am facing a problem with the handling of ESC key in user controls
created in VB.
I have a multiline text box in the control. Also the text box is enabled
since I have to select/copy text in it.
Next I place the control in an MFC dialog. I do not need OK and Cancel
buttons on it and so I remove them and the corresponding handlers. Now,
when I click in the text box and then press ESC key, the text box
disappears and the application crashed.
Strangely, when I used the control in a VB form this problem was not
occuring.
I am using VB 6.0 and VC++ 6.0.
If any can let me know how this may be resolved with VC++, it is greatly
appreciated.
Thanks in advance

You wrote a control in VB6 and are using it in a VC++ 6 app? Am I correct?
I'd would start looking through the C++ code to find where the problem is. We really can help you without code samples and an actual error message. You've given us nothing but a black box and told us "it's broken"... On top of that, this forum really doesn't do VC++ code. You'd have to post the question on the VC++ forum.

ok. im calling a method of my c++ class (active x DLL) from visual basic.
this method call works fine, if there is a single parameter. when i try
to add 2 parameters visual basic says its expects a '=' sign after the call.
the VB call: tp.nothing(i,variable1)
tp.nothing is (id as Integer, string as String)
IDL:
[id(7), helpstring("method nothing")] HRESULT nothing(short *id, BSTR *string);
any ideas why the VB call returns a syntax error???
thanks!

I'm assuming this is VB6? You might want to try:
tp.nothing i, variable1
without the parenthesis. If your not getting a return variable, VB6 doesn't want the parenthesis, but if you are returning a value, you put them around the functions arguments. Wierd and inconsistent, but that's what it wants...

Hey,
I'm a graphics newbie. I built an app with a single form, and a set of controls in it. Now I want to be able to use GDI calls like drawline to draw visual links between these controls. When I use the Paint event of the form, I get a line that goes under my controls, not over it.  Is there a way to get the graphics to lie on top of the controls? Additionally, what's the easiest way to make those graphics go away when they are no longer needed?
Thanks!

I've never done what your talking about, but there are two possibilities...
1) Override the OnPaint eventof your form. The first thing you'll do is call MyBase.OnPaint(e) with the PaintEventArgs you were given in the function header. Then when that call completes, you can use the hWnd handle in the PaintEventArgs to paint everything else you need to, like your lines that go on top of controls.
2) You might have to look into overriding WndProc. What I think your going to have to do is when you get a WM_PAINT message, you'll call MyBase.WndProc(msg) to have the underlying code paint everything for you, then you'll start your painting code to draw your lines as in 1.
I hope that's clear enough...

If your talking about VB.NET and writing a setup for a .NET application, check into the ResourceManager class. MSDN Docs and example[^].

Just go to the Visual Studio icon .
select Microsoft Visual Studion Tools.
from there Select Package and Deployment Wizard and do the process as it said and you will be able to create Your own Wizard.
Hope that it might solve the problem
