Textbox focus

Hi,

on my view i have a Textbox, a Combobox and a Grid (from BCG )

If the focus is on the textbox and the user presses the PageUp Key, the focus
should be setted on the Grid

I catch the Key_Press in the PreTranslateMessage-Handler and verify if the
message is WM_KEYDOWN and the wParam is VK_PRIOR
Then a "Grid->PostMessage(WM_SETFOCUS);" should set the focus on the Grid
and after this i return directly TRUE, so that the Message is not be redirected but
"destroyed"

Does the focus re-enter on the textbox because it was a Key-Stroke?

Big thanks Smile | :)

I am never one to suggest "new GUI behavior", like having Page-Up cause a focus change( OMG | :OMG:

!), but have you tried using Grid->SetFocus()? Using PostMessage(...) causes the set focus message to get queued, but other messages may execute before it affecting the focus.

You also may need to eat the WM_KEYUP message that may get sent to the grid, JIC the grid processes that message.

Peace!

Grid->SetFocus() resolves the problem.

For me, it's logical that a SetFocus()/SendMessage(WM_SETFOCUS) is too early

"...causes the set focus message to get queued, but other messages may execute before it affecting the focus." --> so the keyUp is affected and after this, the grid becomes the focus.

Big thanks to you Smile | :)

Yeah it's strange to change the focus with PageUp, but i re-code an existing DOS-program, which
should keep all keystrokes, because all users are used to use for example this kind of behavior.

The Tab-Key should switch into the different textboxes and a PageUp siwtches to another "section" of the Window

Thanks for your reply.

But can you please tell me under which registry key this service is stored.
Suppose my exe name is ABC.exe and i want to create service for this exe to run in background.

As you send me link on that page they have given key
HKEY-LOCAL_MACHINE\SYSTEM\SERVICES
but can you please tell me under this key where i have to put my exe or where I have to create my new key to run my service in background for ABC.exe

Thanks again!!!!

   It is not really enough to take a normal EXE and throw it into the Services entry in the Registry. A Windows Service is a special type of executable and needs to be written as such. A Windows Service supports control functionality, and the SCM, which manages Services, handles things like authentication and dependencies.

   You should create a new Windows Service project. You should be able to use much of the boilerplate/wizard code as-is and just add your functionality to it.

   Peace!

Hi all,

What am I doing wrong?

// Header File
class TCP32CLIENT

		WaitForSingleObject(handle,7000);

It is because global functions and member functions of a class don't have the same prototype. For the member functions, there is an implicit parameter that is passed which is the 'this' parameter (identifies to which instance of the class it belongs to).

So, that's why your compiler complains. A solution is to use a static function: in that case, the member function doesn't belong to a specific instance of the class but is shared across all instances. In that case, the 'this' parameter is not passed but that also means that you can only access static members of your class in your static function.

Hi,

we have developed one application in which we can download new updated exe from the ftp.

We got success in that process but while downloading new file taskmanager window shows the message Not Responding instead of running.

Can anyone tell me what's wrong going on in my application?

Cedric Moonen5-Mar-07 22:39

Cedric Moonen

5-Mar-07 22:39

If the code is in the main thread, then your application won't be able to respond to GUI events (thus the 'Not Responding' message and the window will stay blank). You need to start your download in a separate thread for that.
