Re: Conversion fron binary file to text file format? Frank K31-Jul-03 20:08 Frank K 31-Jul-03 20:08  Hi, some questions: Is it realy a binary file? (you can't read anything if you view this file with e.g. Notepad). It is also possible, that you can read something with notepad, e.g. if you open a Worddocument as text file. What type of binary file is it? If it is realy a binary file, than you must know the coding rules (the same for decoding) for this type of file. Regards Frank Re: Conversion fron binary file to text file format? koxin31-Jul-03 21:50 koxin 31-Jul-03 21:50  I'm not sure what you want to do, but anyway the difference between binary and text files is that text files are actually subgroup of binary files. That means that bytes (characters) in text files have only certain values specified in ASCII table (e.g. 'a' has a value of 97, 'b' 98, ...) while bytes in binary files can have any possible values (0-255). Thus if you want to display a binary file in a text editor all you need to do is replace all non-ASCII characters with ASCII characters. Then the text editor will not find any character it can't deal with in the file and will consider it to be a text file. Koxin How to get text on screen ? blueinred31-Jul-03 17:19 blueinred 31-Jul-03 17:19  Sorry, it may be a old question, but i couldn't found it ! My mean is very simple, i want my program can hook Right click event and get the text under mouse pointer . Any one can help me ? Re: How to get text on screen ? MartinOrtiz31-Jul-03 18:09 MartinOrtiz 31-Jul-03 18:09  Are you talking about a window in your own program, or any window of any program? The second is almost impossible, because the user could be right clicking over anything, not just text, and even if he did, you would have no way of knowing it. If you want to hook into system wide mouse events, I've heard of that being done, how you would find out what window owns that mouse event or has text, I'm not sure. Re: How to get text on screen ? blueinred31-Jul-03 18:48 blueinred 31-Jul-03 18:48  Sorry ! My mean is anywhere, any program ( IE, Office,....), i've see some program can do that , ah , i'm a vietnamese, we have a good English- Vn e-dictionary is " Just Click'n'See" that can get a English word from screen and display it's Vetnamese mean ! It's so cool ! So i'm want to know the beside tech of it ! Re: How to get text on screen ?

(top) There is no built-in way to do this. Once the text is on the screen, it is no longer readable as a character string, only as a bitmap. You'll need OCR (optical character recognition) software to transform the bitmap back into a string of characters. ______________ Ofcource, there is no built-in way, but it's not a mission possible, try download this program and feel it Just Click'n'See thank ! Re: How to get text on screen ? Toni7831-Jul-03 19:39 Toni78 31-Jul-03 19:39  I know what you mean because I have a dictionary that works by clicking on the words. The thing is that in those dictionaries the programmers know where the words are located. To tell you the truth I don't know what kind of algorithms they use, but trying to get any words that appear on any window doesn't seem to be simple. You are looking at pixels not an edit box. And of course it is not mission impossible, and you can go ahead and try it but it might turn into mission un-feasible. // Afterall, I realized that even my comment lines have bugs When one cannot invent, one must at least improve (in bed).-My latest fortune cookie Re: How to get text on screen ? blueinred31-Jul-03 20:38 blueinred 31-Jul-03 20:38  No, no, no ! Don't simple like that, why u don't try Just Click'n'See one time ! that all my mean ! The core of it's solution is : - Hooking mouse or Keyboard - Get position - Invalid this screen and windows will re-paint it - Hooking output stream and get what u want But what i need is a sample source code But, thank for your comments Re: How to get text on screen ? Toni7831-Jul-03 21:05 Toni78 31-Jul-03 21:05  Sorry but I cannot understand the program because it is in Vietnamese. My reply was intended to tell you that what you are after is not easy. I really cannot help you with your brainstorming because I have never attempted to read text from the screen and I don't think I will in the near future (I usually don't try things unless I have to). With that said and done let me remind you that Einstein (I think) said (not his exact words): "There is something that every man on this planet knows that it cannot be done. Here comes a person that doesn't know that and he solves the problem." Let's hope you will be that person. // Afterall, I realized that even my comment lines have bugs When one cannot invent, one must at least improve (in bed).-My latest fortune cookie Re: How to get text on screen ? koxin31-Jul-03 21:39 koxin 31-Jul-03 21:39  Hi, I'd also like to know a solution to this problem. I'm not proficient in windows programming, but I suggest this: - get the handle of the active window - send the window doubleclick message (this should select the word the mouse is pointing at) - send a message that copies the selection into clipboard - read the word from clipboard maybe that once the word is selected it's also possible to retrive it by sending the window some getselection message or something like that. what do you think? Koxin p.s. if you find a solution to this problem please let me know Re: How to get text on screen ? blueinred31-Jul-03 22:36 blueinred 31-Jul-03 22:36  here a example screen shot Hi, Koxin, i've got a same idea in FAQ and have a example in MSDN but not easy ! And i'm sure have a solution didn't use Clipboard . Any one can suggest another idea ? Coding for lv,lv & di CFormView Background DougW4831-Jul-03 15:53 DougW48 31-Jul-03 15:53  I am having trouble finding a direct way of setting a bitmap as the background of a CFormView. I've done this before using a CDialog class, but as I'm finding, the CFormView isn't quite the same. The bitmap is already defined in the resource file, not loaded at runtime. Thank you for any help anybody can give!! ;) Douglas A. Wright dawrigh3@kent.edu Re: CFormView Background HPSI31-Jul-03 19:53 HPSI 31-Jul-03 19:53  This should be done in the OnEraseBkgnd() handler. In your view class .h file add: afx_msg BOOL OnEraseBkgnd(CDC* pDC); In your view class .cpp file add: ON_WM_ERASEBKGND() Then you can add this function: BOOL CYourFormView::OnEraseBkgnd(CDC* pDC) { // draw the bitmap ... return TRUE; } HPS HwndSpy - GUI developer's aid to visually locate and inspect windows.

Re: disable/enable toolbar buttons in a dialog Marissa18231-Jul-03 15:10 Marissa182 31-Jul-03 15:10  thats how its done if you tool bar control is a member of your dlg class m_Tool.SetButtonStyle(1, TBBS_DISABLED); m_Tool.SetButtonStyle(1, TBSTATE_ENABLED); Re: disable/enable toolbar buttons in a dialog tmangan1-Aug-03 2:00 tmangan 1-Aug-03 2:00  1) If you have a mapped variable for the dialog item: 1A) If it is a static item created with the visual editor: itemmappedvariable.EnableWindow(BOOL); 1B) If it is a dynamic item created on the fly: itemmappedvariable->EnableWindow(BOOL); where BOOL is TRUE or FALSE. Setting to FALSE makes the item greyed out and not selectable by the user, which is what most people mean by disabled. 2) If you want the dialog item to completely disapear, you use: 2A) itemmappedvariable.ShowWindow(var); 2B) itemmappedvariable->ShowWindow(var); where var=SW_SHOW to make it visible var=SW_HIDE to make it disapear. If you don't know what a mapped variable is, either: 1) Ggo to the item in the dialog editor. Click on the dialog item, Right click, select create variable. Fill in the name, hit OK. This makes all the coding changes so that you can use the A syntax above. If you search your dialog .h and .cpp you can see the simple changes and do others by hand. Pay attention to the lack of trailing semicolons if you do. 2) You can also use GetDlgItem(IDC_WHATEVER)->EnableWindow(BOOL) or GetDlgItem(IDC_whatever)->ShowWindow(var). Less efficient this way if you do it a lot. Good luck! tim Founder, TMurgent Technologies www.tmurgent.com tmangan@tmurgent.com Sending "hello world" through com port to other pc.

Updating an Edit control within a loop tdmcclure025631-Jul-03 13:15 tdmcclure0256 31-Jul-03 13:15  Can anyone suggest a way to update an Edit box at run time while in a loop. I've tried using a declared CString variable and updatedata as well as directly updating the control with SetDlgItemText, but neither one update in real time, until the loop finishes execution. Thanks TDM Re: Updating an Edit control within a loop Mike Dimmick31-Jul-03 13:19 Mike Dimmick 31-Jul-03 13:19  Painting is a deferred operation in Windows; WM_PAINT messages are only generated for your windows when the message queue is otherwise idle. To force a repaint of a window immediately, call UpdateWindow.
