Many on these forums know I'm working with the Win API and all is well Except children of a window aren't updating properly. For instance when I create a ToolBar or StatusBar they show up ok and size themselves correctly for the Window's client area, but when I resize the window their size stays the same. However when I click on the control in question it resizes properly. Can anyone with better API knowlege help me to figure what's going wrong?

Pro is not going to handle your resize messages for you. It discards those messages as pro does not use them. What I did was monitor the pro's window size and sent resize/position myself when it was time.

Is there a way to send it to all of a window's child controls or does it have to be implemented individually? Also how did you go about sending the resize/position commands?

Windows has messages to resize/position a gadget.
Sorry, I can't find a page to link to right now.

I understand that xolo what I'm looking for is a way to capture those messages so the I can implement a message handling routine or direct windows to do it for me.

Try sending these messages:
EN_UPDATE 0x0400
EM_AUTOSIZE (1L<<10) `50<<10 ??

Also, look at this:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wceshellui5/html/wce50concreatingacommandbar.asp

In response to your last post,
the messages WM_MOVE 0x3, WM_SIZE 0x5, and WM_RESIZE 0x214 could be read for size change, OR you could specify that the window doesn't resize (see gui.dba)

Those messages are for edit controls only. Oh well this is going to take more research into message handling. If anyone else can help please let me know.

Here is a simple resize function I used in one project.

+ Code Snippet

Function ResizeControls()

`StatusBarText("ResizeControls")
`call dll 1,"MoveWindow",hctlStatusBar,0,0,0,0,1
call dll 1,"MoveWindow",hctl,0,50,windowx-windowoffsetx-174,windowy-windowoffsety-122,1
`call dll 1,"MoveWindow",ConfigurationPanel,windowx-windowoffsetx-174,50,windowx-windowoffsetx,windowy-windowoffsety,1
`ConfigurationPanel=call dll (1,"CreateWindowExA", 0, "static","",dwstyle, windowx-windowoffsetx-173,52,windowx-windowoffsetx,windowy-windowoffsety,hwnd)
EndFunction

Here is the get window size function I used.

+ Code Snippet

Function GetWindowSize
StatusBarText("GetWindowSize")
windowsizeptr=make memory(24)
windowsize=windowsizeptr
a=call dll (1,"GetWindowRect",hctlstatusbar,windowsizeptr)
windowsizeleft=*windowsize
windowsize=windowsize+4
windowsizetop=*windowsize
windowsize=windowsize+4
Windowsizeright=*windowsize
windowsize=windowsize+4
windowsizebottom=*windowsize
windowx=windowsizeright-windowsizeleft
windowy=windowsizebottom-windowsizetop
delete memory windowsizeptr
EndFunction

Dll #1=user32.dll

Maybe they are of help to you.

Not really but thx anyway. I needed something that would work no matter what window was active at the time or what child was active. So a made a function that sends the WM_SIZE (Tells the control to update) to all the Children. I'm trying my best to keep stability by not stealing Messages as someone else told me. It's forcing me to get creative, but be of the Difference between DB/C++ You need to just send the proper messages to the proper controls and they'll do the processing. The framework is there it's just a matter of telling it what to do. I just thought their would be a simpler routine.

Here's what I'm using:

+ Code Snippet

function UpdateAPI()
	`Repaint the controls here.
	First = GetWindow(GetActiveWindow(),GW_CHILD)
	SendMessage(First,WM_SIZE,0,0)
	Current = First
	while Current<>0
	 	Child=GetWindow(Current, GW_HWNDNEXT)
		SendMessage(Child,WM_SIZE,0,0)
		Current=Child
	endwhile
endfunction

function GetWindow(Wnd as dword, Cmd as dword)
	Wnd = Call DLL(user32,"GetWindow",Wnd, Cmd)
endfunction Wnd

This may work even better for you. I just need to implement a conditional statment to check for a size change before calling it, because this will become slow with a lot of controls

I think you should log into msn or yabooger then we can confer. I am interested in finishing my editor also. I think we may have something to share between us.

Look at this, Keaz:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/commctls/richedit/richeditcontrols/richeditcontrolreference/richeditnotificationmessages/en_requestresize.asp
This is the EN_REQUESTRESIZE message I remembered.
And here is how to force an edit to send one:
