Redrawing MSHFlexGrid V.18-Jul-04 23:36 V. 18-Jul-04 23:36  Hi, I have a MSHFlexGrid-like control that often needs to be redrawn. Sometimes the redraw flickers and sometimes it doesn't. It seems to flicker when rows OR cols are out of the direct view, thus enabling the scrollbar. Why does this problem occur and what can I do about it? I didn't know there was significant diffence between redrawing with and without a scrollbar? tnx for your help!

However, I remember that there was an option where you could let the control draw itself automatically. Now I don't know if you have enabled that option and at the same time you are redrawing the grid manually as well. But that would be my first and only guess, because I never had a flickering problem. // Afterall, I realized that even my comment lines have bugs If the sun were to blow up, it would take us 7-8 minutes to realize it. is possible to import structure from DLL?? Anonymous18-Jul-04 22:13 Anonymous 18-Jul-04 22:13  hello, I've got a simple question, some time ago I've wrote an application that creates a binary search tree and now I need it to be used into my win32 appliaction, since importing dll function is not difficult, how do I import structures? I've included in my project the bst.h file that contanins all the definition but at link compiler I get errors... as no bst_node struct is found...... my question is : How I tell the compiler to import a structure from a dll? for all the funcions that needs to be exported I inserted __declspec( dllexport ) but it doesn't work with str. Thanks! Re: is possible to import structure from DLL?? ThatsAlok19-Jul-04 2:49 ThatsAlok 19-Jul-04 2:49  I have better idea for you, Create A class instead of Structure and and made it variable public accesible. and now export/import class using the AFX_EXT_MACRO. note:for this you have to craete the MFC extention Dll ----------------------------- "I Think It will Work" Formerly Known As "Alok The Programmer" at CP ----------------------------- Alok Gupta visit me at http://www.thisisalok.tk Re: is possible to import structure from DLL??

I'm having trouble copying a worksheet in VC++ (MFC). I'm accessing an Excel object and trying to manipulate it. So far, some function that i've used was working fine except the copy function of Worksheet class. There's no error during compilation, but at runtime a message is displayed stating that "Copy method of worksheet class failed." By the way, I am using MS Office 2000. Thanks in advance.

If you are looking for the max value for SetTime(...), look at the function prototype. SetTimer( HWND hWnd , UINT nIDEvent, UINT uElapse, TIMERPROC lpTimerFunc); It looks like uElapse is of type UNIT, so probably the max number of milliseconds is UINT_MAX. Details on UINT_MAX can be found at msdn.microsoft.com Re: Abut timers Anonymous18-Jul-04 21:30 Anonymous 18-Jul-04 21:30  Set timer interval to 1000 (1 second) when creating timer. You will need to create a member data and then increment it in the timer: CMyDialog::OnTimer(...) { m_seconds++; // then you can calculate m_seconds and do whatever // other code } Re: Abut timers vcplusplus19-Jul-04 2:33 vcplusplus 19-Jul-04 2:33  You should use the value returned by SetTimer for KillTimer. From MSDN ========= Return Value from SetTimer(...) The timer identifier of the new timer if the function is successful. An application passes this value to the KillTimer member function to kill the timer. Nonzero if successful; otherwise 0. using static link libraries in vc++ application Kanagu_INDIAN18-Jul-04 18:43 Kanagu_INDIAN 18-Jul-04 18:43  sir i am having one static link library file,i want to create an application by using that library,plz give me the steps which i have to follow in order to use the library CDaodatabase Anonymous18-Jul-04 18:17 Anonymous 18-Jul-04 18:17  In my program, i m using CDaodatabase for database connectivity. i then use CDaorecordset to entry/modify data in the database. My question is:: I do not use DSN anywhere in my program. Does CDaodatabase handle DSN internally. Wat is the better implementation - using DSN or using CDaoDatabase implementation? and wat is the main diff between the two? Re: CDaodatabase vikram attiganal18-Jul-04 19:32 vikram attiganal 18-Jul-04 19:32  CDaoDatabase constructs a CDaoDatabase object. The path to the database will have to be provided and connection can be opened with Open() method. Re: CDaodatabase Anonymous18-Jul-04 21:07 Anonymous 18-Jul-04 21:07  can u point out the difference between connecting vis CDaodatabase and connecting via DSN? Re: CDaodatabase Anonymous18-Jul-04 22:25 Anonymous 18-Jul-04 22:25  DSN stands for Data Source Name. Data Source can be a database, spreadsheet, text file etc. We assign DSN to a data source so that irrespective of the data source details and location, we can use that data source; add, modify or delete records, just by knowing it's DSN. From the application use CDatabase class to connect to a data source. Where as in CDaodatabase, full path to the database needs to be provided to connect. If the path of the data source changes, if a DSN exists, then changing path in the settings is all that is needed. Code doesnt have to be changed. how to highlight a menu item when its position (x and y coordinate) is known 5iveboy18-Jul-04 16:05 5iveboy 18-Jul-04 16:05  Dear programmers, We use a device to provide X and Y coordinates similar to a mouse. Using VC++ I create a very small dialog box and refresh its position using the SetWindowPos funtion (at a rate of 120 HZ and setting it as TopMost window). I can also left-click by bringing the mouse to the corner of the small dialog's position and clicking and sending back the mouse cursor to its original position. This way I fully simulate a mouse cursor. Everything works perfect. Except when the window clicks on a menu (i.e. File, Edit, View, Tools, ...). Then the menu that contains all the menu items covers the small dialog box and user cannot see where they are pointing at. Is there anyway I can highlight menu items when the position of my small dialg box is within the menu item's region? Just like when the mouse moves over the menu item? By the way, remember that the menu item is not a part of my program. It can be in any program. This is the last part of my project. PLEASE PLEASE if you can think of a solution let me know. I have worked on this project for 4 months. I can further explain the program if you want. Thank you in advance, SetCursor outside client area 5iveboy18-Jul-04 15:20 5iveboy 18-Jul-04 15:20  Hi everyone, I am using the SetCursor function of VC++ and I want to be able to set the cursor type not just when the mouse is over my program (client area). I want the mouse cursor to change wherever it is. Any suggestion would be most greatly appreciated. Thanks,
