I would like to customize Windows Explorer.
One thing I want to do is changing file name's color in list view if the file has a special condition.
Is it possible by window subclassing? or does it need api hooking?
Please let me know what is the best way to do this.
Thanks.
Yes, you can do it with the window subclassing:
Add NM_CUSTOMDRAW handler to your CListCtrl-derived class
void CMyList::OnCustomDraw(NMHDR* pNMHDR, LRESULT* pResult)
{
LPNMLVCUSTOMDRAW lplvcd = (LPNMLVCUSTOMDRAW)pNMHDR;
switch (lplvcd->nmcd.dwDrawStage)
{
case CDDS_PREPAINT:
*pResult = CDRF_NOTIFYITEMDRAW;
break;
case CDDS_ITEMPREPAINT:
*pResult = CDRF_NOTIFYSUBITEMDRAW;
break;
case CDDS_ITEMPREPAINT | CDDS_SUBITEM:
lplvcd->clrText = **MY_COLOR**;
*pResult = CDRF_DODEFAULT;
}
}

I'm checking if a button is checkbox of 32bit process on 64bit windows10.
The problem is that I can not distingush checkbox from normal button.
The buttons are different in Window-Detective:
(After I restart the application, even Window-Detective shows it is a button now!)
But the checkbox can't be recognized as checkbox in Spy++
BS_CHECKBOX is not listed.
Code (compiled as 32bit):
TEST_METHOD(ShouldCheckStyle) {
auto styleOfButton = ::GetWindowLongPtr((HWND)0x003F06E8, GWL_STYLE);
auto styleOfCheckbox = ::GetWindowLongPtr((HWND)0x01101642, GWL_STYLE);
auto bsOfButton = styleOfButton & BS_TYPEMASK;
auto bsOfCheckbox = styleOfCheckbox & BS_TYPEMASK;
auto resultOfButton = (bsOfButton == BS_CHECKBOX);
auto resultOfCheckbox = (bsOfCheckbox == BS_CHECKBOX);
auto debugger = 0;
}
Debug output
The code indicates they both have BS_OWNERDRAW. The above behaves the same for the button and the checkbox.
The weird thing is Window-Detective can recognize the style of checkbox. The code is same as I used above. Here's a piece of code:
Window* WindowManager::createWindow(HWND handle) {
WindowClass* windowClass = getWindowClassFor(handle);
String className = windowClass->getName().toLower();
if (className == "button") {
LONG typeStyle = GetWindowLong(handle, GWL_STYLE) & BS_TYPEMASK;
switch (typeStyle) {
case BS_CHECKBOX:
case BS_AUTOCHECKBOX:
case BS_3STATE:
case BS_AUTO3STATE: {
return new CheckBox(handle, windowClass);
}
case BS_RADIOBUTTON:
case BS_AUTORADIOBUTTON: {
return new RadioButton(handle, windowClass);
}
case BS_GROUPBOX: {
return new GroupBox(handle, windowClass);
}
default: {
// If none of the above is true, then the control is just a Button
return new Button(handle, windowClass);
}
}
}
After some discussion, you can use GetWindowText to get the text from each control and compare the specific text.
BS_CHECKBOX cannot be detected from the properties of the "checkbox" control beacuse of BS_OWNERDRAW.
Creates an owner-drawn button. The owner window receives a WM_DRAWITEM
message when a visual aspect of the button has changed. Do not combine
the BS_OWNERDRAW style with any other button styles.
Try the below code:
WCHAR str1[20];
WCHAR str2[] = L"Agree me";
GetWindowText(hwnd_checkbox, str1, 256);
if (_tcscmp(str1, str2) == 0)
{
//it is checkbox
}
else
{
//it isn't checkbox
}
After you get the correct control handle of the checkbox, you can use SendDlgItemMessage or SendMessage to send BM_SETCHECK check message.
SendMessage(hwnd_checkbox, BM_SETCHECK, BST_CHECKED, 0);
I have created a SDL2 application, and would like it to minimize to the system tray, rather than appearing in the task bar.
SDL_MinimizeWindow doesn't do what I want, it leaves the task bar icon. Is there a way to achieve this with SDL?
There is no purely SDL2 way to do this, as Cody said, Shell_NotifyIcon is the function needed to create a notification area (system tray) icon.
The code I used to get the icon is
SDL_Window *window = SDL_CreateWindow("Test", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, 200, 200, SDL_WINDOW_HIDDEN);
SDL_SysWMinfo info;
SDL_VERSION(&info.version);
NOTIFYICONDATA icon;
if (SDL_GetWindowWMInfo(window, &info))
{
icon.uCallbackMessage = WM_USER + 1;
icon.uFlags = NIF_ICON | NIF_TIP | NIF_MESSAGE;
icon.hIcon = LoadIcon(NULL, IDI_INFORMATION);
icon.cbSize = sizeof(icon);
icon.hWnd = info.info.win.window;
strcpy_s(icon.szTip, "Test tip");
bool success = Shell_NotifyIcon(NIM_ADD, &icon);
}
This creates a hidden window, and an icon (using the default information icon).
To interact with this from SDL, you need to enable platform specific window management events, this is done as follows SDL_EventState(SDL_SYSWMEVENT, SDL_ENABLE);
After this, in the main event loop you must test for SDL_SYSWMEVENT, which contains information about how the user has interacted with the notification area icon. This also looks for the minimize event and hides the window which removes it from the task bar. This is achieved in the following snippet
SDL_Event e;
while (SDL_PollEvent(&e) != 0)
{
switch (e.type)
{
case SDL_SYSWMEVENT:
if (e.syswm.msg->msg.win.msg == WM_USER + 1)
{
if (LOWORD(e.syswm.msg->msg.win.lParam) == WM_LBUTTONDBLCLK)
{
SDL_ShowWindow(window);
SDL_RestoreWindow(window);
}
}
break;
case SDL_QUIT:
running = false;
break;
case SDL_WINDOWEVENT:
if (e.window.event == SDL_WINDOWEVENT_MINIMIZED)
SDL_HideWindow(window);
break;
}
}
I want to change font of any cell of CListCtrl control to bold. Can any one tell how to do it for CList Ctrl.
I have already done this for a CTreeCtrl, like this
pTC->SetItemState(hItemCur, TVIS_BOLD, TVIS_BOLD);
do we have something similar for CListCtrl?
Thanks in advance.
If you can use CMFCListCtrl (VS2008 SP1 and up), you can derive a class from it and override OnGetCellFont. From there you return your bold font (you can create your own or return AFX_GLOBAL_DATA::fontBold):
HFONT CMyListCtrl::OnGetCellFont( int nRow, int nColumn, DWORD dwData /*= 0*/ )
{
if (UseBoldFont(/* params */))
{
return GetGlobalData()->fontBold;
}
return NULL;
}
If you have to stick to plain old CListCtrl, the easiest way would be to use Custom Draw, where you can tweak the drawing process to your own needs. Don't confuse it with Owner Draw, where you have to do all the drawing yourself.
Here's an article explaining the basics of using Custom Draw with CListCtrl.
Add
ON_NOTIFY_REFLECT(NM_CUSTOMDRAW, OnCustomdraw)
to your message map.
Now you can simply modify items as you wish in this function. In here you can change the align, font, background-color, text-color, [...], and you can set items to bold -> example. The best way IMO, is to either store a pointer to a struct, class or simply a flag in the LPARAM of the item(s) in the control. This function works for both CListCtrl and CTreeCtrl.
Here is an example with flags:
enum ColorFlags
{
F_COLOR_BLACK = 0x1,
F_COLOR_WHITE = 0x2
//and more...
};
enum CustomColors
{
COLOR_BLACK = RGB(0, 0, 0),
COLOR_WHITE = RGB(255, 255, 255)
};
afx_msg
void CMyListCtrl::OnCustomdraw(NMHDR *pNMHDR, LRESULT *pResult)
{
NMLVCUSTOMDRAW *pDraw = reinterpret_cast<NMLVCUSTOMDRAW*>(pNMHDR);
switch (pDraw->nmcd.dwDrawStage)
{
case CDDS_PREPAINT:
*pResult = CDRF_NOTIFYITEMDRAW; //Do not forget this...
break;
case CDDS_ITEMPREPAINT:
{
switch (pDraw->nmcd.lItemlParam) //Extract color from flags
{
case F_COLOR_BLACK:
{
pDraw->clrText = COLOR_BLACK;
} break;
case F_COLOR_WHITE:
{
pDraw->clrText = COLOR_WHITE;
} break;
default:
break;
} //switch
} break;
} //switch
}
I need to provide a HTML editor functionality in Dynamics Ax 2009.
I figure out a button in a my form the call the html editor provided by SysInetHTMLEditor.
I can call the form with code like this:
SysInetHTMLEditor editor;
;
editor = new SysInetHTMLEditor();
editor.run();
But I have not idea how to use the return, setting the initial text and so on.
I still searching documentation about the class but I can't found it.
Someone can provide me some example?
Finally I found the solution. First, build a class that extends SysInetHTMLEditor.
build a method text:
str text(str text = '')
{
int i;
;
if (prmisdefault(text))
return super();
i = strscan(text, '<body', 1, strlen(text));
if (i)
{
text = strdel(text, i, strscan(text, '>', i, strlen(text))-i+1);
}
return super(text);
}
use "this.text(sometext)" to set initial text (usually on new method)
override save() to save the text (get it with this.text())
override caption method to change caption
override canClose() to save before exit
override isToolEnabled for control tools:
boolean isToolEnabled(int commandId, int tab)
{
switch (tab)
{
case #TABSource:
switch (commandId)
{
case #TOOL_SAVE:
return true;
}
return false;
case #TABPreview:
return false;
case #TABNormal:
switch (commandId)
{
case #TOOL_SAVEAS:
case #TOOL_NEW:
case #TOOL_OPEN:

I found if set TTF_TRACK flag to CTooltipCtrl, SetDelayTime doesn't work anymore, so the tooltip won't disappear automatically. I want to show the tooltip just below specified control, and expect it to disappear after a few seconds(the time can set with SetDelayTime).
Anybody can help me?
Here is my steps to construct tool tip:
1. Add member variable
CToolTipCtrl m_tooltip;
2. override PreTranslateMessage
BOOL CPF_GetSetNameDlg::PreTranslateMessage( MSG* pMsg )
{
switch (pMsg->message)
{
case WM_KEYDOWN:
case WM_SYSKEYDOWN:
case WM_LBUTTONDOWN:
case WM_RBUTTONDOWN:
case WM_MBUTTONDOWN:
case WM_LBUTTONUP:
case WM_RBUTTONUP:
case WM_MBUTTONUP:
case WM_MOUSEMOVE:
m_tooltip.RelayEvent(pMsg);
break;
}
return CDialog::PreTranslateMessage(pMsg);
}
3. OnInitialDialog
BOOL CPF_GetSetNameDlg::OnInitDialog()
{
CDialog::OnInitDialog();
//tooltip
EnableToolTips();
m_tooltip.Create(this , WS_POPUP | TTS_NOPREFIX | TTS_BALLOON);
m_tooltip.SetDelayTime(TTDT_INITIAL, 0);
m_tooltip.SetDelayTime(TTDT_AUTOPOP, 30000);
m_tooltip.SetDelayTime(TTDT_RESHOW, 30000);
m_tooltip.AddTool(GetDlgItem(IDC_SETNAME), _T(""));
m_tooltip.SetMaxTipWidth(600);
}
4. Control to show tool tip
if(bShow)
{
m_tooltip.UpdateTipText(_T("Hello, money~"), pWnd);
CToolInfo sTinfo;
m_tooltip.GetToolInfo(sTinfo, pWnd);
sTinfo.uFlags = TTF_TRACK;
m_tooltip.SetToolInfo(&sTinfo);
CRect rect;
pWnd->GetWindowRect(rect);
m_tooltip.SendMessage(TTM_TRACKPOSITION, 0, (LPARAM)MAKELONG(rect.left, rect.bottom));
m_tooltip.SendMessage(TTM_TRACKACTIVATE, TRUE, (LPARAM)&sTinfo );
}
If you use tracking tooltips then you are responsible for showing and hiding the tooltip manually. The tooltip timers (like "autopop") are ignored. So you need to create your own timer and hide the tooltip yourself when it fires.
