RichEditView Text Frank Deo25-Jul-01 2:11 Frank Deo 25-Jul-01 2:11  Hello, How can I place the entire contents of a RichEditView into a variable? I can do it if the user selects the text, but I would like to do it unselected. Also, is there a limit to the size of a string stored in a CString variable? Thanks! Frank Re: RichEditView Text 25-Jul-01 2:42 25-Jul-01 2:42  I guess you could use GetRichEditCtrl to get the control associated with the view and then GetWindowText. /Per Re: RichEditView Text Frank Deo25-Jul-01 11:54 Frank Deo 25-Jul-01 11:54  Thanks, I'll give that a try.

Please help me quick. Thank You Re: program startup screen Tomasz Sowinski25-Jul-01 1:37 Tomasz Sowinski 25-Jul-01 1:37  From VC++ menu select Project/Add to project/Components and controls/VC++ components/Splash screen Tomasz Sowinski -- http://www.shooltz.com Re: program startup screen 25-Jul-01 1:39 25-Jul-01 1:39  In the MSDN example program Wordpad there is a splash window. Maybe that will help you. /Per Overriding the global "new" operator. 25-Jul-01 1:10 25-Jul-01 1:10  In VC++, is there any way to override the global "new" operator in a DLL and have other DLLs (which link together with this one) and the main program (which links with all the project's DLLs) use this operator? If there is a way, I would appreciate seeing how it is done. My attempts so far have produced the following conclusion: If I add an overloaded "new" operator definition with an additional parameter, e.g. __declspec(dllimport) void * operator new(size_t , unsigned long); There is no error, but as soon as I include the prototype definition of my "new" operator which contains only one argument: __declspec(dllimport) void * operator new(size_t); I get the following error: error C2375: 'new' : redefinition; different linkage C:\TEMP\a00238if(73) : see declaration of 'new' If there is no way to do this in compile time, but there is a way in run-time, I would appreciate seeing how that is done, as well. Thanks, Jacob. Re: Overriding the global Tomasz Sowinski25-Jul-01 1:43 Tomasz Sowinski 25-Jul-01 1:43  The simplest solution would be to implement real allocator as exported function living inside your DLL -- and -- provide overloaded inline operator new that simply calls that function. Operator new would be defined in .h file that all DLLs and EXE would #include.

Please help me! I want to get a word on the screen (eg. on a label, on a button...) by clicking right mouse on it. I guess that I must do some hook to API functions or window's messages, but I don't know how to do it. Please show me the way or send me an example. Once more thank you very much. trungnq.

Christian Graus25-Jul-01 12:08 Christian Graus 25-Jul-01 12:08  Is it the same person asking this question over and over again ? I can't think of a use for this function myself, and I imagine the only way to do it would be with some simulated word selection and copying via the clipboard. I assume the absence of a function that does this is the reason it never gets an answer... Christian #include "std_disclaimer.h" The careful application of terror is also a form of communication. Eagles may soar, but weasels don't get sucked into jet engines. Re: How to get a word on screen by right mouse? august27-Jul-01 11:05 august 27-Jul-01 11:05  check out MSDN on how to do this. what sort of application are you doing? assuming you are using MFC, you want to override CWnd::OnRButtonDown(UINT nFlags, CPoint point). the associated command message is ON_WM_RBUTTONDOWN.

I try to let my program running overnight and when tomorrow morning I found out that it gives me a runtime error. The memory usage increased slowly and this given me the problem (out of memory). Can I know how can I resolve it?? For example, make the memory usage and cpu usage stable. Please help me. Thanks in advance. FM Re: memory usage Gerry25-Jul-01 0:38 Gerry 25-Jul-01 0:38  I use BoundsChecker, to verify that my code has NO memory leaks, this helps prevent this problem. Perhaps you need to redesign your application so it doesn't keep checking or only check every 5-10mins. Gerry. Re: memory usage Farah Mansor25-Jul-01 15:15 Farah Mansor 25-Jul-01 15:15  What is BoundsChecker?? I seen it in other msg too but still don't know what is BoundsChecker. Can you please explain what it is. Thanks for your help.

The CDaoDatabase::CompactDatabase() can only specify dbVersion30 option. Looking at the available options it appears that MFC and DAO hasn't a option for dbVersion40. Re: Converting Jet 3.0 file to Jet 4.0 Hadi Rezaee25-Jul-01 2:13 Hadi Rezaee 25-Jul-01 2:13  For opening the Access 2000 (Jet engine 4.0): You must write: AfxGetModuleState->m_Version = 0x601; Then you can open Access 2000 files with: m_db.Open("C:\\db1.mdb"); // ACCESS 2000 FILE My month article: Game programming by DirectX by Lan Mader. Please visit in: www.geocities.com/hadi_rezaie/index.html Hadi Rezaie Re: Converting Jet 3.0 file to Jet 4.0 Doug Garno25-Jul-01 2:23 Doug Garno 25-Jul-01 2:23  Yes you are correct, that is what is required to Open a Jet 4.0 file, but that doesn't convert the file from 3.0 format to 4.0. Re: Converting Jet 3.0 file to Jet 4.0 Tomasz Sowinski25-Jul-01 2:33 Tomasz Sowinski 25-Jul-01 2:33  dbdaoint.h contains the following enumeration... typedef enum DatabaseTypeEnum { dbVersion10 = 1, dbEncrypt = 2, dbDecrypt = 4, dbVersion11 = 8, dbVersion20 = 16, dbVersion30 = 32 } DatabaseTypeEnum; ... so it seems that dbVersion40 equals 64. You can also use Object Viewer in Visual Basic to check the actual value from type library. Access 2000 should also have this defined. Anyway, let me know what happens with 0x40 Tomasz Sowinski -- http://www.shooltz.com Re: Converting Jet 3.0 file to Jet 4.0 Doug Garno25-Jul-01 3:24 Doug Garno 25-Jul-01 3:24  That worked: CDaoWorkspace::CompactDatabase( csOld, csNew, dbLangGeneral, 64 ); I was leaning that way but I thought I would just ask the experts here and save me some time. Thanks for your help.
