How to get a CWnd-pointer from hWnd?? Mr.Freeze10-Jan-02 21:05 Mr.Freeze 10-Jan-02 21:05  Hi, My question might be a little bit stupid, but How do I manage to get the pointer to a window if I only have the window's handle ?? Thanks Re: How to get a CWnd-pointer from hWnd?? Prem Kumar10-Jan-02 21:12 Prem Kumar 10-Jan-02 21:12  Use CWnd::FromHandle. Re: How to get a CWnd-pointer from hWnd??

Pls tell me the possible ways to create such a Control. SSN Re: VeryUrgent Nish Nishant10-Jan-02 19:36 Nish Nishant 10-Jan-02 19:36  What for? Can't you use ADO?

I know that MySQL and Postgres have C APIs. I dont know about SQL server and Access. Oracle has a C/C++ library too. Then people can generically use your control and your control can use the library specific to the target DB.

Re: VeryUrgent 10-Jan-02 20:10 10-Jan-02 20:10  If I get the file path of the database(Access), is there any way to check whether any table is existing in that or not? If yes then how is it possible to get the table name?? Re: VeryUrgent Christian Graus11-Jan-02 1:17 Christian Graus 11-Jan-02 1:17  Yes, you can do all that using ADO. There are tutorials on this site and in MSDN. However, you seem to be contradicting yourself a bit, you should take a step back, consider what you're trying to achieve, and consider if you provide more specific information, we might be able to help you a bit more.

And Lord *knows* between ODBC, DAO and ADO, we need something else.

It just annoys people. 2/ So you want to *use* a M$ database accessing technology to create a control that accesses databases, you don't want to write your own version of ADO/DAO/OBDC ? I did however mean exactly what do you want thins thing to do ? Do you have any prior experience using ATL ? Creating ActiveX controls ? Using ADO/DAO/OBDC ? I'm just trying to get an idea of what you're actually trying to achieve *specifically* and how much you already know about the process you're proposing.

SSN Re: Data Base Prem Kumar10-Jan-02 21:17 Prem Kumar 10-Jan-02 21:17  Assuming that u are using DAO, since u refer to flat files(path to Database!) Use CDaoDatabase::GetTableDefCount and CDaoDatabase::GetTableDefInfo And Compare the Table Name in the CDaoTableDef::m_strName returned. Get the executable file path 10-Jan-02 15:43 10-Jan-02 15:43  Given the handle to a app instance or a window, how to obtain the path of the executable file? e.g "c:\winnt\notepad.exe".

AnonymousBabe@usa.net10-Jan-02 14:06 AnonymousBabe@usa.net 10-Jan-02 14:06  assume a windows client 's height and width is yClient,xClient, what's the relation between the ScrollInfo structure 's member nMin,nMax and the yClient,xClient; assume the font's height is ftheight, the client window should contain yClient/ftheight lines buffer(buffer[yClient/ftheight][]). if there is already yClient/ftheight LINES buffer displaying in the client area. when the scroll box is moved , assume member nPos in the ScrollInfo structure amount to 1, then the buffer[0] will dispear, and the Client Area shows the buffer from the 2nd row in the buffer, and so on. then if nPos=yClient/ftheight，the the scroll box is showed in bottom of Scroll Shaft? can anyone explains those concept about usage of ScrollBar?thanks in advance a lot sorry for my poor english. one is the other who absorbs the thoughts of others one is the other who absorbs the thoughts of others Re: what's the usage of ScrollBar? Christian Graus10-Jan-02 14:42 Christian Graus 10-Jan-02 14:42  I'm not sure what you're asking, but if a bitmap is 800 pixels high and the window that shows it is 300 pixels high, the scroll range will be 500, because at position 0 you see the top and at position 500 you see from 500-800, i.e. all the way to the bottom.

Is there anyway(which i sure there is) to correct this height difference and how...? TIA P.S-This is only my second question posted on an online message board...i've never chatted, joined forums or anything so i'm unsure of the proper etiquette or forum ehtics. What i'd like to know is...will i be hated if i ask too many questions...? "An expert is someone who has made all the mistakes in thier field" - Niels Bohr
