Disabling a Key of Keyboard

15-Jun-07 6:36

Download the Platform SDK (version Server 2003 R2 or newer) - the DirectShow SDK is included.

There's enough documentation and sample code there to get you started pretty quickly.

If you run into specific problems, don't hesitate to ask here Smile | :)

Is that virtual-key code VK_APPS (0x5D) ?

Hello. I have an SDI application where i pace a resource dialog as a child window. The problem is that the dialog is taller that the main frame so a part of the dialog is not showing. Can someone give me an advise where and how to resize the main frame according to dialog size? Thanks in advance!

To size any window, check out SetWindowPos() and MoveWindow().

Is this MFC? If so, in your CFormView's OnInitialUpdate call:

ResizeParentToFit(FALSE);

The boilerplate code created for SDI in VS2005 does not include the FALSE which allows the parent to grow.

MDI, dynamic menus & lost system menus

Hello everyone!
I have the following problem in my MDI App.
If my MDIChildView is not maximized I remove the main menu
of my MDIFrame (SetMenu(NULL)). Then I maximize my view
and I set my frame main menu to the original menu (SetMenu
(pOrgMenu)). The menu appears, but the control menu
(maximize, minimize, close button) of my child view don't
appear in the menu bar, as it should do.
The only possibility that I have is to call
MDIRestore()
MDIMaximize()
of my child window. But this results in an ugly window
flash.

I have already tried all things I know about MDI frames
and child views, but non of that worked.
Has anyone an idea, how I can solve this problem?

The only thing i found with google was "nothing" Frown | :(

Thank you to everyone, if he has a solution, or (sigh) not!!

You may need to call DrawMenuBar to get it to display correctly.

If you vote me down, my score will only get lower

Hi!
Thank you for the answer!!

Yup, in theory yes (at least when my app was only SDI this thing worked well). But let me explain beter the situtation:
1) I don't use doc/view style, seen that i use several kind of views, from activex to rtf to everything can be nice to use as "plugin", i can't then use the trik to change the menu through the document template
2) It exist only the menu bar for the CMDIFrameWnd, that is dinamically modified/created/deleted following the users desires Smile | :)

3) the thing that appear is something like [windows grey thingy ][_][menu contents][[]][X]
it return ok only with a MDIRestore->MDIMaximize sequence but under XXXXXXX windows XP and Vista the animation make this process SLOOOOOOOOOOOOOOOOOOW
4) This thing happens only when i follow this process
a) no menu exist and there is an MDIChild maximized
b) i create the menu for the mainframe

The solution i tried (and used) was to lock every window of the app during this restore/maximize sequence but is a mess, i dont like to simulate user action only to satisfy the gui oddities Frown | :(

BTW thank you for the answer, because i did not specified that i where already using DrawMenuBar

Disconnection of Socket

Hai !

suggest me to perform the socket disconnection in VC++ 6.0.

I used "close" and "shutdown" to perform socket disconnection but when saw through TCP View the socket remaining connect.

Onther one, To disconnect we have to perform both the side client and server operation or client side only enogh.

How did you connect it? Is closesocket() what you are looking for?

CImage::Create(...) lets me create an alpha channel,

but how do I change the bits in it?

I'd like to use TextOut and create a blurred shadow effect for a text image.

if you want to set some effects to your images or texts you can use of GDI+ for example(GetTextContrast or Graphics::DrawString) and also CImage has a function AlphaBlend that you can use of it.

The CImage::GetPitch() and CImage::GetBits() methods provide direct access to the image's pixel
data.

CImage::GetBits() gets you a pointer to the image pixel data.

CImage::GetPitch() is the bytes-per-row, and if it's negative, CImage::GetBits() returns a pointer
to the LAST row of the image, so you can use the signed value returned by CImage::GetPitch()
to iterate through the rows of pixel data.

The layout of the pixel data varies depending on the format of the bitmap.
For a 32bit-per-pixel ARGB image, the pixel data bytes are layed out RGBARGBARGBA... so if you
take each pixel as a DWORD, the high order byte is the alpha channel byte.

Hope this helped!
