Hello Folks, I am back with yet another WinCE / Windows Mobile Solution this time it is something exciting and it is on Power Batter Suspend timeout related stuff.

Hello Folks, I am back with yet another Win CE / Windows Mobile articles, i don't want call this as an articles rather i would like to call it as some quick peek into WinCE / Windows Mobile useful functions. Lately i have a requirement where i need to run my application in full screen mode which means i have to disable task bar to let my application run n full screen mode.

CWnd* pWnd = CWnd::FindWindow(L"HHTaskBar", L""); if( pWnd ) { if( blnHide ) pWnd->ShowWindow(SW_HIDE); else pWnd->ShowWindow(SW_SHOW); } return; } //ShowHideTaskBar Thats it ... simple right !!!!!

I am back and yet again Windows Mobile / WinCE tutorial but this time soemthing interesting and on networking side. Lately i was developing Wireless PDA Update application which requires me to check if server which contains ROM image files is reachble before attempting to download files from the same. I thought that there is a WinCE API available to perform this task but to my surprise there is NO direct API however helper API is available. Then i have constructed an API which takes parameters and returns true if ping successful. Here is the function .... If you require full application do let me know so that i can upload to any free server. int Ping(PWCHAR wszHostname, int iWaitTime) { WCHAR wszAdd[MAX_PATH] = L"\0"; in_addr addr; HANDLE hFile; IP_OPTION_INFORMATION ipInfo ; IPAddr ipAddress ; ICMP_ECHO_REPLY icmpEcho; int iRet = ...
