I am getting this error by compiler when I compile my code in VC.NET. Note it was previously compiled correctly in VC 6.0 .

e:\Microsoft Visual Studio .NET 2003\Vc7\atlmfc\include\afxdlgs.h(430): error C2146: syntax error : missing ';' before identifier 'm_pdex'

Any reason. I shall be very grateful.

Best Regards,

Hi,

In stdafx.h
Try changing WIN_VER to 0x0501, which is Windows XP and 2003 specific.

Hi everyone,

I am trying to create an array dynamically with CString, here is an example:

<br />
CString *a = new CString [nSize];   // nSize defined somewhere else<br />
<br />
// Some operation here ...<br />
<br />
delete a;<br />
<br />

but I catch an exception ....
Would you mind suggest the problem here?
Thanks a lot~

Is it possible to display unicode characters of different languages at the same time to a single edit box?

Sanghamitra22-Nov-05 20:20

22-Nov-05 20:20

We have an EditBox control. We have the following questions:

1. Is it possible to paste different characters (say, 1 japanese, 1 chinese, 1 spanish, 1 hindi and 1 arabic) in the control without changing the characterset or the locale? MS Word does the same. Any idea how it can be done?

2. Is there any generic/universal characterset that supports most of the fonts and the unicode standard?

3. What does UCS do and how it is used?

Download Platform SDK from MS site or
try this Non PSDK api :- CreateToolhelp32Snapshot followed by Process32First and Process32Next

Hi Alok

I have downloaded and installed Platform SDK. I have setup all the paths. But still it is giving linker error saying

"error LNK2001: unresolved external symbol _EnumProcesses@12
fatal error LNK1120: 1 unresolved externals"

Am using VC 6.0

Insert this code in your cpp file.

#pragma comment(lib,"Psapi.lib")

actually problem is, you forget to include the library file which has defination of EnumProcess api

Anyways, it will be better to use these apis CreateToolhelp32Snapshot(...),Process32First(...) and Process32Next(...), here is code snippet to achieve same. here, m_mapProcesses is type map<CString,DWORD> m_mapProcesses;

HANDLE hProcess;
PROCESSENTRY32 ppEntry;


// Clear Memory
ZeroMemory(&ppEntry,sizeof(ppEntry));
ppEntry.dwSize=sizeof(ppEntry);

// Get SnapShot of All process
hProcess=CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,NULL);

// Check if we able to get snap shot
if(INVALID_HANDLE_VALUE==hProcess)
    return FALSE;

if(!::Process32First(hProcess,&ppEntry))
{
    CloseToolhelp32Snapshot(hProcess);
    return TRUE;
}

BOOL bTrue=TRUE;

while(bTrue)
{
    //Save the File
    this->m_mapProcesses[ppEntry.szExeFile]=ppEntry.th32ProcessID;

    if(GetLastError()==ERROR_NO_MORE_FILES)
    {
        CloseToolhelp32Snapshot(hProcess);
        return TRUE;
    }

    bTrue=Process32Next(hProcess,&ppEntry);


}


//Close snapshot
CloseToolhelp32Snapshot(hProcess)

MFC80UD.DLL was not found

Abyss22-Nov-05 19:49

Abyss

22-Nov-05 19:49

I migrated a VS2002 solution to VS2005 (MFC application with some DLLs). It compiles without any problem - the warnings from _tcscpy and such methods was fixed. However I can't run the application because it can't locate the MFC80UD.DLL module. When I check the application in Dependency walker it loads without any problem. Even in the Debugger's output window I can see that the given modul loaded the symbols. It reports:

Debugger:: An unhandled non-continuable STATUS_DLL_NOT_FOUND exception was thrown during process load

I also tried to move the MFC module to System32 folder however it caused another failure during the application start - some manifest issue. To be honest I do not understand this - at least I don't know how to fix it. I just know that this stuff solves the DLL hell problem - different versions of the same DLL.

Any idea what is wrong?

Thanks,
Abyss

I continued with my investigation and found that if I copy the missing MFC80UD.DLL module from the WinSxS folder to the application's folder then the debugger shows the following:

'App.exe': Loaded 'C:\Out\App.exe', Symbols loaded.
...
'App.exe': Loaded 'C:\WINDOWS\WinSxS\x86_Microsoft.VC80.DebugMFC_1fc8b3b9a1e18e3b_8.0.50727.42_x-ww_c8452471\mfc80ud.dll', Symbols loaded.
...
'App.exe': Loaded 'C:\WINDOWS\system32\winspool.drv', No symbols loaded.

Here the module not found message is displayed if the MFC module is not at app folder.

'App.exe': Loaded 'C:\Out\mfc80ud.dll', Symbols loaded.

Well and I'm surprised, because the MFC module gets loaded twice. Can explain anybody why?

Abyss

Having trouble with a namespace and class type collision in C++/C# project

dxben22-Nov-05 19:46

22-Nov-05 19:46

I have a C++ app that includes a 3rd party library that has a type called
'System'. This class exists in a namespace, let's call it XYZ::System.

Then I am compiling my C++ app with /clr and somehow when VC8 includes
xlocale (which in turn uses a macro defined in yvals.h) that calls a method in .NET (System.bla.bla) there is an ambiguity.

How can I resolve this easily?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
