Hi,,,,
I have one GUI i.e,SDI application which is inherited from Form view
I want to add Key maaping to that GUI.
For that when i press 'a' i have to focus on One button
when i am press 'A' then i have to focus on another button.
//There is a problem in KEYDOWN MessageMap related to my application.
So,I use PreTranslate message to handle key events.but when i press 'a'it will treat that as 'A'.
so,please help me in this Regard.

I think if u handle WM_CHAR instead of WM_KEYDOWN, you can identify 'a' and 'A'.
|

Thanks for the Reply...
But i have some problem when using WM_CHAR and WM_KEYDOWN message maps.
So,Can i Handle it in "PreTranslateMessage"..
any suggestions.......

You may use GetKeyState(VK_SHIFT) [^] to distinguish between lower case and upper case keys in PreTranslateMessage.

And when caps Lock Key is on?

Make a try before arguing 
(i.e. CAPS LOCK key down makes GetKeyState(VK_SHIFT) returning the same value it returns whenever SHIFT key is held down)

But I tried now. GetKeyState(VK_SHIFT) is not giving the same value when shift key is down and when CAPS LOCK key is on.
Did you actually check like this..?
if( GetKeyState(VK_SHIFT)&0x8000 )
|
|
|
|
|
Well, actually it is not the same value, but bit 0 contains the meaningful info in both cases, hence GetKeyState(VK_SHIFT) & 0x0001 should do the trick.

I dont think so. Cause the low bit indicates the key is toggled. Suppose the application is started and at that state
if( GetKeyState(VK_SHIFT) & 0x0001) - > will return false.
Then I press shift key and release it. After that
if( GetKeyState(VK_SHIFT) & 0x0001) - > will return true.
Then if i again press shift and release,
if( GetKeyState(VK_SHIFT) & 0x0001) - > will return false.
So basically, checking the 0 bit have no meaning in the case of shift key. 0th have use only in the case of toggle keys such as CAPS LOCK, NUM LOCK etc...

Again, make a test.

Hi,
I used following codes to Open window when double click to the Systray Icon.
No error detected when i compiled the codes. However, the codes does not working...
Any other alternate way to Open window when double click to the Systray Icon???
PLease help me???/
LRESULT CMainFrame::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
// Open window when double click to the Systray Icon
if(message == MYWM_NOTIFYICON){
switch (lParam){
case WM_LBUTTONDBLCLK:
switch (wParam) {
case IDR_TRAYICON:
ShowWindow(SW_NORMAL);
SetForegroundWindow();
SetFocus();
return TRUE;
break;
}
break;
}
}
return CFrameWnd::WindowProc(message, wParam, lParam);
}
regards

Hi Naveen,
Not working also??

Show how you added the tray icon and the entry in the message map.

You don't say whether you've debugged your code. Compiling cleanly is MILES away from actually doing what you've asked it to do.
Try doing:
LRESULT CMainFrame::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
if(message == MYWM_NOTIFYICON
{
ASSERT(FALSE);
switch (lParam){
Then see if
(a) message MYWM_NOTIFYICON ever arrives - if not, look at how you set up your little icon.
(b) do you then get the dblclk message?
(c) and does wParam equal your code?
The show-my-window code looks fine to me (no guarantee though!), so I'd concentrate on the wiring to detect double clicks.
Lastly, use the pre tag as described in the "read this before posting" message. The rules there are good ones. Without formatting, your code is hard to read. And you're just lucky you don;t use any <s or >s.
Iain.
Plz sir... CPallini CPallini abuz drugz, plz plz help urgent.

Hey,
I have seen some similar discussions on this, but thought there might be an answer out there..
My problem:
When I call VirtualAlloc() with a specific memory address, say 0x60abcdef for 100000 bytes, it will fail.
A subsequent virtualQuery sometimes often indicates that it is memory mapped region. The thing is, I haven't loaded any libraries, or memory mapped any regions.
Is there a way to figure out what is in this memory, or who allocated/memory mapped it? And/or strategies for ensuring that as much of the user space virtual memory is as empty as possible?
(I know my process,ntdll and user32.dll aren't mapped to this region either)

When every you run an application the exe's and dll's associated with that application is loaded into the memory as a memory mapped file. So may be to that locations some dlls is mapped.If you u took the moudle window in the visual studio, you can see from which address to which address each modules are loaded. So take the module window and see if any dll falls in the memory location 0x60abcdef.

I don't think its the process exe as it was at 0x400000 and the only other two dlls loaded were ntdll and user32 which were in the upper 0x7's... Would a thing like an onboard video card with shared memory use a memory mapped file (or something similar) in user space ?

Ofcourse no. They steal physical memory, not process memory.
Did you check your process with "Process Explorer". All the memeory mapped files of a process will be listed in it.
