Using UpdateResource() to change app's icon kb23-Jul-02 0:49 kb 23-Jul-02 0:49  Hi, I am trying to write a small utility that allows users to customise the icon of my program, which is a precompiled EXE (similar in function to MicroAngelo etc, but much simpler, with only the option of choosing the new icon, which will then be applied to the EXE). I believe UpdateResource() can do this for NT (and the _UpdateResource class over at http://www.codeguru.com/misc/resources.html does pretty much the same for Win 9x). However, I can't figure out how to use UpdateResource correctly. I can't even get the sample code from MSDN to compile correctly. Could anybody tell me how I can use BeginUpdateResource(), UpdateResource() and EndUpdateResource() to swap the icon in an EXE file for another .ico file (ie the end user will just have to select an .ico file)? Many, many thanks to anybody who can help or give me any pointers.

This is done calling CHtmlView::Create(...) Now the problem is that Create fails and returns false If I bring it up from the main dialog, it works. It only fails when I bring it up from the 2nd dialog Is there any way to figure out why and how Create is failing This project is compiled with the /clr option by the way as it uses a good amount of managed code. Thus the debugging features are sorta mostly useless. I created a test dialog app, added a child dialog and popped up a frame window with the CHtmlView derived view and made it a /clr app. That worked with no issues at all. Do you guys think that with all the managed code, I am causing some kinda memory overflow or some other problem for MFC??? I feel miserable!

I created and showed my frame window before all the managed stuff and now there are no problems. Weird eh? of course this hasnt solved my issue. The last thing I want is to have the frame window jumping up before even the dialog is shown Can someone throw some light on this pathetic darkness???

Create my frame window in my OnInitDialog but turn off the visible bit in the flag. Now whenever I want to bring up the framewindow with my custom view I do a ShowWindow with SW_SHOW Of course now I have to override WM_CLOSE in the framewindow and instread of actually closin it I hide it And I dont have to bother about a leak because the framewindoiw is destroyed when the dialog is closed because the framewindow's parent is set to the dialog CWnd Cool, eh? Regards Nish p.s. I know this sounds really silly and ugly, hey that rhymes, silly, ugly , well coming back to what I was saying, I dont have any other smarter ideas!!!

Sprudling23-Jul-02 8:28 Sprudling 23-Jul-02 8:28  I take it there is no such function, and there is no problem really except compiling takes 10 times longer when not using precompiled headers. Sprudling Re: wait/sleep func for win32 console apps? Daniel Lohmann23-Jul-02 9:58 Daniel Lohmann 23-Jul-02 9:58  Oh the compiling time - I see. You could decrease it a lot by defining some symbols to exclude rarly used stuff from the windows headers: #define WIN32_LEAN_AND_MEAN in front of your #include statement should help a lot. But of course, you could also take the one-line definition of Sleep out of the header and define it on your own, so you just don't need the header: extern "C" void Sleep( unsigned int msec ); should do it (don't forget to link against kernel32.lib) -- Daniel Lohmann http://www.losoft.de How to determine the device? bigcake22-Jul-02 20:53 bigcake 22-Jul-02 20:53  How to distinguish from MO,Zip and Card reader without finding out lable.

And which is more interesting , is although fopen fails , the file actually has been created.? Thanks. Re: fopen failes Stuart Dootson22-Jul-02 20:51 Stuart Dootson 22-Jul-02 20:51  I don't think fopen sets the last error code on failure - GetLastError is a Win32 thing, whereas fopen is part of the C run-time library. Don't know why the second bit should happen - it always helps to look at the source for the library (although you may not have it installed).

Here I am going to draw a rectangle in any region of window. VIKS Re: Control detection Aggtaa23-Jul-02 1:32 Aggtaa 23-Jul-02 1:32  Yep. No problem Just 1st) enumerate all windows in system (EnumWindows, or, much eaier in case of ONE target window - EnumChildWindows) 2st) determine if they do have target window (one, or did i mis anything?) like BOOL CALLBACK EnumChildProc(HWND hWnd, LPARAM lParam) { CMyDlg *pDlg = (CMyDlg*)(AfxGetApp()->m_pMainWnd); HWND hTempWnd = hWnd; while (hTempWnd != NULL && pDlg->IsTargetWnd(hTempWnd )) hTempWnd = ::GetParentWnd(hTempWnd ); if (hTempWnd == NULL) return TRUE; ... } 3rd) get their rects with GetWindowRet, 4th) if needed convert them into client coordinates (ClientToScreen & back ScreenToClient) 5th) check if they lay inside traget rect with (IntersectRect and some additional work in case of target rect lays fully inside some controls) 6th) that all falks, like MGM said Cryst How to send message to another program? RichardWdy22-Jul-02 19:20 RichardWdy 22-Jul-02 19:20  I wnat to run another prog. in my prog. So I need seng messare to the prog. I have two questions: 1.What's wrong with the following code and How to send message to a check ctrl? HWND hEditFilter = GetDlgItem(g_hExefile, ID_CHECK_EDIT); // return NULL??? // g_hExefile is the handle of another prog's dialog. PostMessage(g_hExefile, BM_SETCHECK, ID_CHECK_EDIT, 0); // no respond // I want to set the check ctrl in FALSE state. 2.How to send message to a commom dialog(like OK button)? Thanks. No pains, no gains. Re: How to send message to another program? Williams23-Jul-02 4:49 Williams 23-Jul-02 4:49  Heare are the steps and code to send messages to another program. 1. Remember that on Windows all are windows, so you need to get a HWND to your target window. 2. With the target HWND you call GetDlgItem to retrieve a handlw to window control. 3. Send the message to the window´s control directly. code: // buffer to get the target caption window returned by // GetWindowText char szWindowName[60]; CString szTargetWindowName = "MyApp"; // Target window int nFound; int nLength = strlen(szTargetWindowName); HWND hSearchHandle; //Search around our "MyApp" for(hSearchHandle=::GetWindow(::GetDesktopWindow(),GW_CHILD);hSearchHandle; hSearchHandle = ::GetWindow(hSearchHandle, GW_HWNDNEXT)) { ::GetWindowText(hSearchHandle, szWindowName, 20); szWindowName[nLength] = '\0'; nFound = lstrcmpi(szWindowName,szTargetWindowName); if(nFound == 0) { CWnd pCwnd; // WPARAM 1: Check, 0: uncheck ::SendMessage(::GetDlgItem(hSearchHandle,<put heare="" your="" control="" id="">, BM_SETCHECK,1,0); } } if you have any problem with the code above contact me . Asta la vista. Re: How to send message to another program? RichardWdy23-Jul-02 5:38 RichardWdy 23-Jul-02 5:38  Thanks for giving me help. I think the code may has some problem.(I didn't test it yet.) I want to send BM_SETCHECK message to an edit(ID = ID_EDIT_START) and your code showed that you send BM_SETCHECK message to main window. It won't work. So I need to get the edit control's handle (It's where my problem really exists, I can't get the handle). By the way, the external dialog program has several edit controls. Thanks again. Richard Woo No pains, no gains. Re: How to send message to another program? RichardWdy23-Jul-02 5:52 RichardWdy 23-Jul-02 5:52  I made a mistake with the former reply. I tried this: ::SendMessage(::GetDlgItem(hSearchHandle, ID_EDIT_START), BM_SETCHECK, 1, 0); No response at all. I have solved it in another way. My question has a little change. How to get a special edit control in a dialog program's handle? Could you help me? Thanks a lot. Richard Woo No pains, no gains. Re: How to send message to another program? Williams23-Jul-02 6:47 Williams 23-Jul-02 6:47  Hi, BM_SETCHECK works only to checkbox buttons!! Talk more about your last question! Re: How to send message to another program? RichardWdy23-Jul-02 18:06 RichardWdy 23-Jul-02 18:06  Thank you. I want to run another dialog program. It has several edit controls. I want to fill the edit controls automatically, which requests send message to the edit control. I tried several ways, but I couldn't the handle of the edit control. The following is my code. HWND h = ::GetDlgItem(hDlg, ID_EDIT_START); // hDlg is the handle of the dialog. h return NULL. Could you tell me what's wrong? How can I perform that? Richard Woo No pains, no gains.
