I´m not using it, I just #include "FolderDlg.h" and use it this way : BOOL CDlgEnsayoObs::BrowseForDataStore () { CCableOkApp* pApp = (CCableOkApp*)AfxGetApp(); CFolderDialog dlg(this); CString path; LPCITEMIDLIST pidl; BOOL bRet = FALSE; pidl = dlg.BrowseForFolder(_T("Seleccione el directorio de Almacén de datos"), BIF_USENEWUI |BIF_RETURNONLYFSDIRS | BIF_STATUSTEXT ,NULL ,TRUE); path = dlg.GetPathName(pidl); if (path.IsEmpty ()) { return bRet; } else { pApp->m_sDataFilePath = path + "\\"; pApp->m_sDataStorePath = path + "\\"; SetDlgItemText(IDC_FILEPATH, "Seleccione un grupo de cables o Dir. de captura"); SetDlgItemText(IDC_DATASTORE, pApp->m_sDataStorePath); pApp->m_DataBase.SetDataStore(pApp->m_sDataStorePath); bRet = TRUE; } dlg.FreePIDL(pidl); // liberar PIDL cuando se termina--importante!! return bRet; } In my project is not _DbgName in any place. It´s only in the DiLascia code inside a debug.h file. I´m not including nor added to my project this two files, debug.h and debug.cpp. I´m only including FolderDlg.h, FolderDlg.cpp, where the functions I want to use are declared/implemented. Anyway FolderDlg header is already including debug.h ...

In fact it is in debug configuration where the linker errors came. When I compile in release, all is ok... So I´m missing something in my debug config? this line is a comment in the code // You must link shlwapi.lib for StrRetToBuf could this be the problem? If it is... how do I link shlwapi.lib ? thx again. jdg

Done :) thanks. ups... sorry resource explorer! was hidden.. stupid me. =/ Well the previous part compiled ok, but I´m using too this code from MSDN by Paul DiLascia where he encapsulated SHBrowseForFolder in a class FolderDlg... http://msdn.microsoft.com/msdnmag/issues/05/06/CAtWork/default.aspx At VS2003 it was working ok... but now I´m having this fatal error... So my project still can´t compile :( please any help apretiated . thanks in advance.

Hi all I have loaded (a copy just in case) of my project from VS2003 at VS 2005, it was converted fine with just a few errors that I fixed but I still have this one that I dont understand. I´m not an expert, I´ve few months programming MFC self learning and still a lot to learn. The error Line : static CALLBACK CallbackProc(HWND hwnd, UINT msg, LPARAM lp, LPARAM lpData); The compiler error: error C4430: missing type specifier - int assumed. Note: C++ does not support default-int Can I continue with my MFC project at VS2005 with no problems at all? Why I cant see my dialogs, main form , etc.. just the code? Where are they!!? thx in advance. Jdg

Hello I´m trying to do this : A user starts to write his username in an editcontrol, and as he types Im searching in a database finding any coincidences with other data I have... If found one i will show it in other editcontrol else I will disable it. So at what event from the editcontrol should I put my code? EN_UPDATE ? EN_CHANGE ? or this is not the best way..? thx in advance...

Hello I´m inserting a bitmap image in my dialog with a picture control, and i want it to be transparent like when you insert an icon in a dialog, and you set the background colour to some kind of green at visual studio icon editor and it do the trick. So, what background color should I use with bitmaps? btw I´m using Visual Studio 2003 IDE. thank´s. -- modified at 8:53 Thursday 24th August, 2006

It works now!! thanks a lot for your help :)

Yes, is dialog based and I have doc/view classes too. The wizard created me a View class, and i read that there I should do my drawings, I´m going by the book... Hope it isn´t wrong :S ... I just realize that when I logon the user and then resize the main window manually, the new user is displayed correctly. It works :) but how do I call that ::OnPaint method in my View Class from the logon dialog when I press Ok? That´s what i don´t know to do... thank´s

It´s not related, just that in this class is where i do all my drawing stuff and the first time i write the user at the main window, I do it from this class.

class CRegisterAppView : public CScrollView
{
protected: // Crear sólo a partir de serialización
CRegisterAppView();
DECLARE_DYNCREATE(CRegisterAppView)
.
.
.
}

thanks

Hi, I´m new here and im self learning vc++ and mfc programming, add to this that I´m spanish speaking native, so please excuse my english, I will do my best so you all can understand me. Well, what I´m doing in resume is this : I have a CDialog logon screen in my program, where the user enter his password and username. So I need to save the user and update the Main window with who just logged in. By the way, I´m working in a Dialog Based App. So in my class RegisterApp : public CWinApp I do this :

class RegisterApp : public CWinApp
{
public:
RegisterApp();
CString sActiveUser;//A member var to save the active user.
.
.

I Initialize it :

RegisterApp::RegisterApp()
{
sActiveUser = "No user logged";
}

Then at my RegisterAppView::OnPaint() I show before the login that there´s no user: I can see it well at the Main window that is at the background, and at front "OnTop" I got the little logon window.

RegisterApp* pApp;
pApp = (RegisterApp*)AfxGetApp();
dc.TextOut(105,60,"Usuario activo : " + pApp->sActiveUser);

I don´t know if this is the best way, but it works and shows what I want at this moment "No user logged" . Now, when the user logs in I do this :

bool CDlgLogon::FiltraDatos()
{
RegisterApp* pApp;
pApp = (RegisterApp*)AfxGetApp();
CString sIdUsuario;
GetDlgItemText(IDC_EDTLOGONUSER, sIdUsuario);
.
.//some code to check the user...
.

    pApp->sActiveUser = sIdUsuario;

.
.
}

Ok, I´ve just updated sActiveUser, I got the user in a var out of the logon dialog function, So I think I will not loose it(I´m right?), but now I need to update the Main Window with this value, in graphical mode using dc.TextOut... Is correct that I should call the RegisterAppView::OnPaint() method again to show the actual user?. If it is, How do I do that from my dialog? Is this the correct way to do this? thanks in advance :) Jarley "Don't panic!. All will become clear in time"
