According to your answer to CPallini, your buffer contains a BMP file. So, wiki[^] should contain all the information you need to access the pixel data. Also look for BITMAPFILEHEADER, BITMAPINFO and such structures in MSDN, these should help too. You could for example use CreateDIBSection[^] to get a HBITMAP from your data and use it to feed it to a picture (static) control or draw it yourself.

Hello,
Please any one tell me where i can get message IDs for registered activex controls?
I want to automate MSFlexgrid control or MSdatagrid control using Perl. This requires sending message to those controls. But I could not find any document containing grid control messages. I could get Message ID s of most of the controls (commonly used) in winuser.h and commctrl.h. Thank you in advance.

ActiveX (i.e. COM) controls have their own way (i.e. interface methods) to interact with.

I'm not an expert but this page [^] looks promising.

I am working on Vista with VS 2005.
In my application, I am handling the WM_POWERBROADCAST message and in the message handlig function, execution some code which i must execute when the system goes to hibernate or standby(sleep) mode.
I find that on Vista, windows doesnot wait for the WM_POWERBROADCAST message handling function to return a value(true or false) before proceeding to entering into sleep mode.
On Vista, the system goes to sleep mode even before the WM_POWERBROADCAST message handling function returns a value. And because of this, my application does not have enough time to execute code in the handler function and results in a crash.
Should Windows go/not go to hibernate/sleep mode depending on the return value of the WM_POWERBROADCAST handling function?[MSDN Link]

The following is from the documentation -
To prevent the system from transitioning to a low-power state in Windows Vista, an application must call SetThreadExecutionState to inform the system that it is in use.

I tried calling the SetThreadExecutionState() function in the OnInitDialog() of an sample dialog based applicaiton with various combinations of flags ES_CONTINUOUS ES_SYSTEM_REQUIRED | ES_DISPLAY_REQUIRED, but to no avail.
Could you please tell me as to which flag is to be used with SetThreadExecutionState()?
|
|
|
|
|
I guess you have to call SetThreadExecutionState inside the WM_POWERBROADCAST handler.

sometimes I can get a handle of a windows easily,but I need a pointer of the window object,how can i do this?
thanks in advance!
|

You can attach the handle to a newly created object.
CWnd* pNewWnd = CWnd::FromHandle(hWnd);

first i created a window object,then i get the handle of the object, after that i send the handle to another function,if i attach the handle to a new object,does it mean i have two identical object ?
|
|
|
|
|
You will then have 2 objects that work on the same window handle.

is there any way to retrive the original object?
|
|
|
|

Both objects are independent.
They only works on the same window handle.
So you will have to keep the reference yourself.

For that i gave you one function SetWindowPos. Did you try calling SetWindowPos and change the size of the dialog? Or you are looking for ready code ?
Regards,
Sandip.
