I am trying to write a program which needs to interact with other programs.For this i need to find the handle of its window and have the user select the right windows. I am thinking of enumerating all windows and put the in a dropdown box. I was able to do this with visual basic but the code does not work wiht vb express. I need some pointer to find the solution.

View 1 RepliesMy application uses an MDI form, and there are instances where the end user will need multiple child windows open at a time. I need an easy way for the user to switch between windows, which made me think of using tabs kinda like Firefox, or like the tabs in the Visual Studio IDE up at the top where you can switch between open forms and code files.
I'm curious if there is a control in .NET that will already do this? I would rather not re-invent the wheel if I can help it. Google has failed me thus far.
The app Im working on is dunning on an embedded xp machine. It recieves input from the serial port from an industrial process, and then a backgroundworker class calculates and updates the single form GUI with the results from the process. Very simple.Now, the customer want to allow automatic download of log files by an USB memory. The process should work like this:
1)User plug in an usb memory
2)SHow a virtual keypad (touch screen) where the user enter a security code
3)If code ok, show a 3 choice screen, if not ok show error message and allow the user to try again.
4) If user choose the "export all" button, this choose form will close and i display another form with a progress bar that show how all files are copied to the usb memory. When this process is complete, I will display teh form that says "remove the usb memory and press ok to restart the application.
As you see here lots of forms are created and disposed based on user choices. My biggest issue here is that I have no clear design pattern to work from.For example.. should I have this "chain" in the main gui form, or should I let each form create the next form. For example on the "select action" form, when I press export, should this form create and show the "copy progress" form, or should all forms be created and destroyed from the main gui form?
Also, such an issue like with the password. I put it as a constant on the main form, to avoid "magic numbers" in the code. And then I ran into problem because the "keypad" form is created on another thread and I can't access the costant on the main form, so I got a cross thread exception.Everything starts when an USB memory is connected. And the OnConnected eventhandler is running on a different thread than the main UI thread. how to design this chain of window creation/deletion is greatly appreciated. I show all forms with the SHowDialog because I dont want the user to be able to close the form unless he/she presses a button. And not by accident press somewhere else.
I would like to find out what the current windows sleep mode setting is i.e. Is it switched on and what is the timer period. My preferences (in order) are:

What is the best way to handle resolution issues on the monitor when writing a windows app from VB.Net.I developed an app on my laptop, it's widescreen and res is set to 1440 x 900.

View 2 RepliesI have searched other forums, google, etc. and have not find a solution. I am creating a VB.NET application using Visual Studio 2010. My application runs fine inside the IDE. Outside of the IDE, it crashes immediately with an OOM exception. I have compiled the program in both VS 2010 and VS2008. The outcome is always the same. I increased my Desktop heap to 12288 meg from 3072 meg thinking that was the issue, but the outcome is the case. Although the increase does improve my response in the IDE. The error is also being reported as related to mscorlib.dll; and my version is for 2.0 framework is 2.0.50727 and for 4.0 framework is 4.0.30319. I am running Windows XP/SP3.

It will bring the windows calculator window to the top and set the value "1" on it.Is it possible to send the keystroke without poping the window?
For an app. I'm making I need to find all the windows that belong to a process.
From all of this windows I want to have the handle and title.
I'm trying to show all window titles including the corresponding icons, much like Windows Task Manager does. This works only to a certain extent though - although I am able to get the windows' title bar texts, the icon is not always available.
For getting the icon I pass the WM_GETICON message to SendMessage (source):
Public Const WM_GETICON As UInteger = &H7F
Public Function GetWindowIcon(ByVal WindowHandle As IntPtr) As Icon
Dim IconHandle As IntPtr = SendMessage(WindowHandle, WM_GETICON, 0, 0)
[Code].....
For some windows, this returns just the correct icon. For others, it returns Nothing since IconHandle is equal to 0. In Windows Task Manager and on the taskbar they show up just fine.

I wrote an application to handle a joystick with directinput. It works fine if it uses the handle of the main window but it doesnt happen the same if the handle is the one of the component that contains the joystick's operation.
I mean:

component handle (which is inside the window and the joystick needs the focus of this component to work): 25
It always work if the handle i initilizate the device is the main form (15).How can i use only the handle of the component?
