Hi,Everyone:

when i build the program in server machine, it runs well; but if i build it in local machine and upload, then i got a Runtime Error.

<br />
-Microsoft Visual C++ Runtime Library-<br />
<br />
d:\vcydcj.exe<br />
<br />
abnormal program termination.<br />

is it normal, cos the difference of Op-System?

Server Machine: Windows 2000 Professional
Local Machine: Windows Xp

& it seemed problem happened when it runs to these code:

<br />
CADOParameter pParamIn_Readnum(CADORecordset::typeInteger, sizeof(int));<br />
pParamIn_Readnum.SetValue(pMydoc->rwbossdlg.m_nReadNum);<br />
CADOCommand pCmd(pAdoDb_RB, "ydcj_getdata_574");<br />
pCmd.AddParameter(&pParamIn_Readnum);<br />
pRs_RB = new CADORecordset(pAdoDb_RB);<br />
pRs_RB->Execute(&pCmd));<br />

Thx!

I want to write a utility to turn off the Direct3D and DirectDraw function.

I can turn off the function by the following procedure :

a. Open "Run" in "Start" menu and type "Dxdiag".

b. Select "Display" tab, and click the "Disable" button with "Direct3D Acceleration"

But I can't find solution that uses Windows API or other way.

Could someone help me to find out how to implement this function?

Thanks!

API to make listbox user-viewable only

i use CreateWindowsEx to create a listbox and make its single item selected by code, i don't want the user to change the selected item index. i tried EnableWindow to disable the listbox window but it disabled the scrollbar of the listbox as well. What API should i use to make the listbox viewable only? which message should i process to prevent users from selecting another item in the listbox? (API solution only!)

Handle the LBN_SELCHANGE[^] message and reselect the item you want to be always selected.

Put your load image code in InitDialog (LoadBitmap, LoadImage etc) but process drawing in OnPaint (BitBlt, ..strecht...etc).

Well I'm doing some mysql connections for a database project I'm working on. The documentation says it requires VC++ 7.1 The version I'm running appears to be a 7.0.2. Now I've only been back in the Visual C++ world for about... 2 weeks. Is the Studio 2005 supose to be 7.1?

Thanks for any info.

I'll add that Microsoft have been working like beavers to get thier C++ implimentation standards compliant. That's probably the reason for the version problem, although I thought the big jump was from 6.0 to 7.0.
