(i have to move to nextdlgctrl than) i see no getactdlgctrl or similar resp. main problem is GetDlgItem(ID_MYCONTROL)->Enablewindow(FALSE); not moves to next control automaticaly (has to?) i have no special nextctrl handler thanks for reply t!

Retrieving registry values Steven Gregg31-Oct-01 5:18 Steven Gregg 31-Oct-01 5:18  Have the following code as part of my DLL running on NT Workstation. For some reason it opens the registry key OK but can't Query the value. The value is definately in the registry. Interestingly, when I cut and paste the code into a standalone .exe it works fine. Anyone any ideas...is it a problem with UNICODE or similar? //GET REGISTRY INFORMATION FOR DATABASE NAME // HKEY hKey; if (ERROR_SUCCESS == RegOpenKeyEx( HKEY_LOCAL_MACHINE, "SOFTWARE\\COMPANY\\PRODUCT", 0, KEY_QUERY_VALUE, &hKey ) ) { DWORD dwBufLen; char szDBName[256]; if (ERROR_SUCCESS == RegQueryValueEx( hKey, "DatabaseName", NULL, NULL, (LPBYTE) szDBName, &dwBufLen) ) { OtherFunction(szDBName); } else { OtherFunction("\\default\\Data\\MyDatabase"); } RegCloseKey( hKey ); } else { OtherFunction("\\default\\Data\\MyDatabase"); } Cheers Steevie Re: Retrieving registry values Michael Dunn31-Oct-01 8:28 Michael Dunn 31-Oct-01 8:28  DWORD dwBufLen; char szDBName[256]; You need to init dwBufLen to the size of your data buffer so the API knows how large your buffer is. char szDBName[256]; DWORD dwBufLen = sizeof(szDBName); --Mike-- http://home.inreach.com/mdunn/ If there's something strange / in your VC code / Who you gonna call? / Ghostbusters! your with and Dependency Walker / DLL functions -Dy31-Oct-01 4:30 -Dy 31-Oct-01 4:30  Hi all, Does anyone know how I can find out what is available from a DLL in code? I can find out what DLL's an app/dll requires (cause I got the code from MSDN ), but I'd like to take this a step further and find out what the DLL offers and what gets used by a calling app/dll. Much like the way Dependency Walker does it... Cheers, Dylan Re: Dependency Walker / DLL functions Bernhard31-Oct-01 4:56 Bernhard 31-Oct-01 4:56  if you right click on the dll in the explorer there comes this menu up.. if you use the second function ( under "open with" should be sthing like "view item".. i don't know that exactly cause i am using the german version of the os) you should see all the exportet functions of this dll... hope this works for you... bernhard ""Politicians and diapers have one thing in common.

Re: Dependency Walker / DLL functions -Dy31-Oct-01 5:52 -Dy 31-Oct-01 5:52  Thanks for the note, but I'm trying to do this in code Any suggestions anyone? Re: Dependency Walker / DLL functions #realJSOP31-Oct-01 6:11 #realJSOP 31-Oct-01 6:11  This is kind of tricky to do. An exported function can be represented by a name or an ordinal. If they use an ordinal, all you have is the integer value. If it's a name, it could be mangled. All exported functions are written to the exports table. the exports table contains the name (and address to the entry point) for each exported routine. Look on MSDN for articles about the dumpbin utility.

It is possible to see the version with the Windows font viewer so I guess it must be possible to get the file version. Does anyone know how to get the font file version programmatically with a API call or something like that? Thanks for your help in advance! Jens Doose access violation Gérald Mercet31-Oct-01 3:23 Gérald Mercet 31-Oct-01 3:23  I have a strange pb with my application: My app is a dlg application in which i have to use a ADO connection with an Access database: CString strTemp; strTemp.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\\SwaptionCalculator\\ParameterFile.mdb;"); _bstr_t strCnn(strTemp); In the last line there is a pb i have never met before today(i would like to specify that this lines haven't be changed since i have started my application, and it runned very well before today!) So, if i try to run my application, a message arrives, telling me this thing: "unhandled exception, ....0x00000005. Access Violation" This happened when the app is at line of the following declaration: _bstr_t strCnn(strTemp) So, i would like to know what is the problem, and i thank in advance people who can help me gerald Re: access violation Michael P Butler31-Oct-01 3:32 Michael P Butler 31-Oct-01 3:32  Have you tried debugging into the _bstr_t constructor. I can't believe that line can be giving that error. What other code have you changed recently? My guess is something has corrupted memory. Michael Re: access violation Gérald Mercet31-Oct-01 3:39 Gérald Mercet 31-Oct-01 3:39  it's exactly what i think sthg corrupt memory, and i have changed nothing in my code which could break it. But, ihave tried to put a breakpoint in the _bstr_t constructor, which could initialize a _bstr_t object from a char* object, i have put this break point at the beginning of the constructor, and the application failed at this moment Re: access violation Michael P Butler31-Oct-01 3:44 Michael P Butler 31-Oct-01 3:44  Something in your code must have changed or you are loading some different data into memory somewhere. I'm not sure why you are using .Format when a simple assignment would do the job. You may need to post the code for the rest of the function so that we can help better. Michael Re: access violation Gérald Mercet31-Oct-01 3:49 Gérald Mercet 31-Oct-01 3:49  you will find in the following post all the code concerning the dlg app. The function CalcHWEuropeanSwaption is defined in another part of my code, but it has no relation with the ado connection. void CSWAPTIONCalculatorDlg::OnBermudanswaption() { BermudanSwaption ber; double swaption; UpdateData(TRUE); ::CoInitialize(NULL); try { _ConnectionPtr pConnection=NULL; CString strTemp; CString strParam,strParamFin; int decimal,sign; strTemp.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\\SwaptionCalculator\\ParameterFile.mdb;"); _bstr_t strCnn(strTemp); TESTHR(pConnection.CreateInstance(__uuidof(Connection))); pConnection->Open(strCnn,"","",adConnectUnspecified); swaption=ber.CalcHWEuropeanSwaption(m_dlgStartDate,m_dlgSwaptionEndDate,m_dlgSwapEndDate,0,1,1,0.03,0.03,"TauxZCEuro","SurfaceVolatilite"); m_dlgPrice=swaption; strParamFin.Format("%.5f",m_dlgPrice); CEdit* Edit=(CEdit*)GetDlgItem(IDC_PRICE); Edit->SetWindowText(strParamFin); pConnection->Close(); } catch(_com_error &e) { AfxMessageBox("a pas bon"); } ::CoUninitialize(); } Re: access violation Michael P Butler31-Oct-01 4:10 Michael P Butler 31-Oct-01 4:10  You say the code used to work and that you haven't changed anything. What about the data that you are putting into the dialog? Have you tried rebuilding all your project, sometimes the debug info can get out of synch with the source code and make you look in the wrong places. I'd be tempted to move the strTemp and _bstr_t code to the top of the function. See if it crashes on the same line of code or in a different place. Michael Re: access violation Tomasz Sowinski31-Oct-01 3:33 Tomasz Sowinski 31-Oct-01 3:33  It probably has nothing to do with access violation, but why are you using CString::Format? Is the code you've posted a real stuff or a simplified version? Tomasz Sowinski -- http://www.shooltz.com Re: access violation Gérald Mercet31-Oct-01 3:43 Gérald Mercet 31-Oct-01 3:43  it's just a part of my code, as i'm a beginner in ado connection, i have read some articles about it, and i have found this way of proceeding. So, if you want to suggest me another way of doing, feel free to do it. TLS Maer72731-Oct-01 2:34 Maer727 31-Oct-01 2:34  - If I just use the function "TlsAlloc" and do not use the function "TlsSetValue", I think we just allocate an index and do not allocate a memory space to store value of variable. - Am I right? - Regards, Maer
