That's not a legend at all, that's exactly what happened. AFX got scrapped because it was too hard to use.

compile errors with GDI

Hey!

The steps I have taken setting up GDI+ through VC++ so far.
1] Get the MS SDK.
2] Go to Tools->Options->Directories and add the "include" and "lib" directories of the MS SDK folder.
3] Go to Project->Settings->Link and add "gdiplus.lib" to the "Object/library modules" linked list field.
4] Use "#include gdiplus.h" in stdafx.h.

Total newb question:
I get compile errors after step 4]. I have not yet used any GDI-based objects in my code. The errors stem from just having the "#include gdiplus.h" in stdafx.h.

Some of the compile errors:

The compiler stops at 100 errors. I figure I'm not including a needed library, but I'm lost. If anyone has any recommendations I'd be very grateful.

Thanks for your time.

Hi ,

How to debug the applications which uses the setEventHook for mouse for all the applications. All the mouse events that are generated while using the debugger itself will be noise.

HI!
I am working on an application, very simple one. it is an mfc dialog based application.
As, i have to deal with xml files through my application, so, i had written the statements:

#import "msxml3.dll"
using namespace MSXML2;
in the header file of my application.
The program is neither giving any error message nor any warnings. But, it is giving RunTime Error "The application has requested the runtime to terminate in an unusual way. Please contact the application`s support team for information."
What may be the cause?How to remove this problem.
I had not used abort anywhere in the program.

Thanx

Hello everybody,
I have problem , I want to edit a record in a database and don't understand how to do it.
Situation is like this :

Suppose I have Client.mdb database and a Table

Name Surname<br />
<br />
David Gates<br />
Nick  Allen<br />
Rick  Ellison

then I have next code :

    ...
    CString Sql;
db.Open("Clients.mdb"); // db is CDaoDatabase variable
Sql = "SELECT * FROM Clients";
recset.Open(AFX_DAO_USE_DEFAULT_TYPE,Sql,NULL);

    recset.Move(1);
// Here I want to Edit second record and change
    // Nick Allen to Bob Allen

recset.Close();
db.Close();
    ...

Could anyone provide me a little sample code about how to edit the second record?

thanks

Hi You can use SQL commands to edit your records

<br />
Sql = "UPDATE Clients SET Name='Bob' WHERE Name='Nick' AND Surname='Allen'";<br />
db.Excute(Sql);

or Create a class with Base CDAORecordSet & the uose code like

...<br />
 recset.Move(1);<br />
// Here I want to Edit second record and change         <br />
// Nick Allen to Bob Allen		<br />
recset.Edit();<br />
recset.m_Name = "Bob";<br />
recset.Update();<br />
recset.Close();<br />
...

to Create CDaoRecordeser Based Class U most add new MFC class & select CDaoRecordset as Base Class the IDE ask you to select your DB & table (VS 6.0)
in VS .Net 2003 you most add new "MFC ODBC Consumer" Class ....

There is no special pattern to design the source code of threading stuff.
But it strictly depends on the type of threads you want to implement.
A UI thread is represented by a C++ class derived from CWinThread.
A worker thread is reperesented by a controlling function like this:

UINT MyThreadProc(PVOID pParam);

I usually create two files Thread.h and Thread.cpp and put the worker
threads there; in Thread.h I put declarations and in Thread.cpp definations of controlling functions. Though this standard is not strictly necessary.

You also may use worker threads in a class. In this case the controlling function must be a static member-function of that class.

...
Try to specify your Q.

g_pDlgControlPanel=new CControlPanelDlg();
g_pDlgControlPanel->Create (IDD_CONTROL_PANEL,this);

g_pDlgControlPanel->SetWindowPos(NULL,0,CONTROL_PANEL_TOP,rcMain.Width(),rcMain.Height(),SWP_NOZORDER);
g_pDlgControlPanel->ShowWindow (SW_SHOWNORMAL);
//after executing this code above ,the new position is incorrect ,

Hey all I'm trying to build a small simple application that links to another lib file. I have built the lib project and everything compiles fine and it creates the .lib file. Now when I create a new project link it to the .lib file and try and use the classes etc from it. The program compiles fine but I get linking errors
Error 1 error LNK2019: unresolved external symbol "public: virtual __thiscall Wac::Forms::Window::~Window(void)" (??1Window@Forms@Wac@@UAE@XZ) referenced in function __unwindfunclet$??0MainWindow@@QAE@XZ$0 MainWindow.obj

this goes on for each method I use form the .lib.

Now i'm trying to get back into this, so sorry if its soomething easy that i missed. I had the working in 2003, now i have 2005 beta 2 and i'm trying to get it set up. So i'm not sure what the difference it in the build settings.

Hope someone can help.

thanks

It most probably means that your lib project depends on some other lib file and the linker is not able to find that when it tries to build the application.

Hello guys,
I have next problem : I am working in Visual Studio.Net 2003 and want to create a class CMyRecordset derived from CRecordset , but when I click Project->AddClass->MFC Class and want to choose CRecordset as a base class of my class , I can not find the CRecordset among the listed MFC classes.
In Visual Studio 6.0 I did it easily , after choosing CRecordset as a base class the I chose the fields I needed and Tables.I want to do the same here.
What am I doing wrong???
Can anyone help?

thanks
