WINCE6.0 Storage memory和Program memory调整引起异常问题
WINCE6.0系统下ROM-only FileSystem，在控制面板下有系统这项：
图1
只要稍微一拖动就跑到最右边，选择OK后，如果我打开桌面的IE，弹出无法执行“iesample”
图2
重启后恢复为设置之前的，现在我想要的效果就是让它保留，但禁止拖动或是拖动无效，如何解决！有几种办法：
1. 修改源代码
相关代码在\WINCE600\PUBLIC\WCESHELLFE\OAK\CTLPNL\CPLMAIN\system.cpp文件的MemoryDlgProc函数中，只需要在WM_INITDIALOG消息处理部分禁止IDC_TRACKBAR刻度条的窗口对mouse和keyboard输入的响应，通过调用：
::EnableWindow(hwndSlider , FALSE)
来实现，相关代码如下：
extern "C" BOOL APIENTRY MemoryDlgProc (HWND hDlg, UINT message, UINT wParam, LONG lParam)
{
MemoryState *pMemoryState;
pMemoryState = (MemoryState *)GetWindowLong(hDlg,DWL_USER);
// if we don't have our state, don't process
if(message != WM_INITDIALOG && !pMemoryState)
return FALSE;
switch (message)
{
case WM_INITDIALOG:
{
TCHAR szTemp[100];
DWORD PageSize, TotPages, StoreUsed, RamUsed, StorePages;
GetMemoryInfo(PageSize, TotPages, StoreUsed, RamUsed, StorePages);
pMemoryState = new MemoryState;
if(!pMemoryState)
{
ASSERT(0); // Couldn't create persistant storage
return FALSE;
}
else
{
ZEROMEM(pMemoryState);
SetWindowLong(hDlg,DWL_USER,(LONG)pMemoryState);
}
pMemoryState->fSliderMoved = FALSE;
// save this for restore if we fail
pMemoryState->orgStorePages = StorePages;
// Init the slider
HWND hwndSlider = GetDlgItem(hDlg, IDC_TRACKBAR);
::EnableWindow(hwndSlider , FALSE);//kandi add at 2013.12.26
WORD wMax = (WORD) (TotPages / TICK_RESOLUTION);
SendMessage(hwndSlider, TBM_SETRANGE, TRUE, MAKELONG(1, wMax));
SendMessage(hwndSlider, TBM_SETTICFREQ, (wMax / 75), 0L); // tick freq.
SendMessage(hwndSlider, TBM_SETPAGESIZE, 0L, 3); // page up/dn size
SendMessage(hwndSlider, TBM_SETPOS,TRUE, StorePages / TICK_RESOLUTION);
// init the current allocations
_snwprintf(szTemp, ARRAYSIZE(szTemp) -1, CELOADSZ(IDS_SYSTEM_MEMKBYTE), StorePages * PageSize);
szTemp[ARRAYSIZE(szTemp) -1] = 0;
SetDlgItemText(hDlg, IDC_STATIC_LEFT, szTemp);
_snwprintf(szTemp, ARRAYSIZE(szTemp) -1, CELOADSZ(IDS_SYSTEM_MEMKBYTE), (TotPages-StorePages) * PageSize);
szTemp[ARRAYSIZE(szTemp) -1] = 0;
SetDlgItemText(hDlg, IDC_STATIC_RIGHT, szTemp);
// init timer so we can update
pMemoryState->idTimer = SetTimer(hDlg, 2, 1500, NULL);
MemoryDlgOnTimer(hDlg,pMemoryState);
AygInitDialog( hDlg, SHIDIF_SIPDOWN );
return 1;
}
case WM_TIMER:
MemoryDlgOnTimer(hDlg,pMemoryState);
return TRUE;
case WM_HSCROLL: // track bar message
switch LOWORD(wParam) {
case TB_BOTTOM:
case TB_THUMBPOSITION:
case TB_LINEUP:
case TB_LINEDOWN:
case TB_PAGEUP:
case TB_PAGEDOWN:
case TB_TOP:
pMemoryState->fSliderMoved = TRUE;
MemoryDlgOnSlider(hDlg);
return (TRUE);
}
break;
case WM_COMMAND:
switch (LOWORD(wParam))
{
case IDOK:
{
if(pMemoryState->fSliderMoved) {
MemoryDlgOnOK(hDlg, pMemoryState->orgStorePages);
}
if (pMemoryState->idTimer) {
KillTimer(hDlg, pMemoryState->idTimer);
pMemoryState->idTimer = 0;
}
return TRUE;
}
}
break;
case WM_SYSCOLORCHANGE:
// fwd the syscolorchange to our trackbar
SendMessage(DI(IDC_TRACKBAR), message, wParam, lParam);
break; // return FALSE anyway so DefDlgProc handles it for ourselves
case WM_DESTROY:
// we won't get this far if the
delete pMemoryState;
SetWindowLong(hDlg,DWL_USER,0L);
break;
}
return (FALSE);
}
编译办法：
F:\WINCE600\PUBLIC\WCESHELLFE\OAK\CTLPNL-----Rebuildand clean sysgen
Rebuild current BSP and Subprojects----------ok，但如果此步选择是makerun-time image，则控制面板下部分程序显示的是英文。
或是直接采用来替换掉windows目录下的文件cplmain.cpl，不需要重启。
2. 修改rc文件
对应文件为\WINCE600\PUBLIC\WCESHELLFE\OAK\CTLPNL\CPLMAIN\cplmain.rc文件，相关内容如下：
//@CESYSGEN ENDIF
//@CESYSGEN IF CPLMAIN_SYSTEM
//
// System dialogs
//
IDD_MEMORY DIALOG DISCARDABLE 0, 0, 132, 140
STYLE DS_CONTROL | WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS
BEGIN
LTEXT "Move slider to the left for more memory to run programs. Move it to the right for more storage space.", IDC_STATIC,5,2,120,26
LTEXT "Only unused RAM (black portion of the slider bar) can be adjusted.",IDC_STATIC,5,30,120,16
//orinigal
//CONTROL "",IDC_TRACKBAR,"msctls_trackbar32",TBS_AUTOTICKS |
// TBS_TOP | TBS_ENABLESELRANGE | WS_TABSTOP,3,47,124,22
//kandi change at 2013.12.26
CONTROL "",IDC_TRACKBAR,"msctls_trackbar32",TBS_AUTOTICKS |
TBS_TOP | TBS_ENABLESELRANGE | WS_TABSTOP|WS_DISABLED,3,47,124,22
LTEXT "Storage",IDC_STATIC_STORAGE,12,70,64,8
LTEXT "memory",IDC_STATIC_MEMORY1,12,78,64,8
LTEXT "Program",IDC_STATIC_PROGRAM,81,70,64,8
LTEXT "memory",IDC_STATIC_MEMORY2,81,78,64,8
LTEXT "1,000KB",IDC_STATIC_LEFT,5,89,29,8
LTEXT "1,000KB",IDC_STATIC_RIGHT,72,89,29,8
LTEXT "total",IDC_STATIC_ALLOC_LEFT,34,89,27,8
LTEXT "total",IDC_STATIC_ALLOC_RIGHT,101,89,27,8
LTEXT "in use",IDC_STATIC_IN_USE_LEFT,34,98,33,8
LTEXT "in use",IDC_STATIC_IN_USE_RIGHT,101,98,33,8
LTEXT "640KB",IDC_IN_USE_LEFT,5,98,27,8
LTEXT "640KB",IDC_IN_USE_RIGHT,72,98,29,8
END
只需要在下面设置刻度条属性基础上或上WS_DISABLED即可
CONTROL "",IDC_TRACKBAR,"msctls_trackbar32",TBS_AUTOTICKS |
TBS_TOP| TBS_ENABLESELRANGE | WS_TABSTOP,3,47,124,22
修改之后：
CONTROL "",IDC_TRACKBAR,"msctls_trackbar32",TBS_AUTOTICKS |
TBS_TOP| TBS_ENABLESELRANGE | WS_TABSTOP| WS_DISABLED,3,47,124,22
编译办法：
F:\WINCE600\PUBLIC\WCESHELLFE\OAK\CTLPNL-----Rebuildand clean sysgen
Rebuild current BSP and Subprojects----------ok，但如果此步选择是makerun-time image，则控制面板下部分程序显示的是英文。
但这种办法对于英文系统是有效的，对于非英文系统控制面板下大部分程序，包括这次修改的显示都是英文。
3. 修改res文件
比如对应英文系统，在\WINCE600\PUBLIC\WCESHELLFE\OAK\LIB\ARMV4I\RETAIL和\WINCE600\PUBLIC\WCESHELLFE\OAK\LIB\ARMV4I\RETAIL、0409下都有systeml.res文件，都要同时修改，比如修改显示的内容做了下面的编译测试都无效，目前还不知道原因，先备忘：
修改systeml.res文件
F:\WINCE600\PUBLIC\WCESHELLFE-----sysgen
Clean sysen整个工程
-----不OK
F:\WINCE600\PUBLIC\WCESHELLFE-----sysgen
sysen整个工程
--------------不行
F:\WINCE600\PUBLIC\WCESHELLFE\oak-----sysgen
make run-timeimage----------------------------
-----不行
总结：采用第1种办法，直接修改源代码，这样对于其他语言都有效，但如果对于RAM and ROM 文件系统来说，如何要兼容，就要知道RAM and ROM文件系统多了下面的注册表信息：
; HIVE BOOT SECTION
[HKEY_LOCAL_MACHINE\System\StorageManager\AutoLoad\ObjectStore]
"Dll"="filesys.dll"
"Paging"=dword:1
"LoadFlags"=dword:1
"BootPhase"=dword:0
"MountPermanent"=dword:1
; Only mountObjectStore FS as root if PRJ_ENABLE_FSMOUNTASROOT is NOT set
; in order topreserve backwards compatibility (ObjectStore is root of
; virtual filesystem by default).
"MountAsRoot"=dword:1
; END HIVE BOOT SECTION
或是通过其他办法
