Yes.

Set the path to executables in the VC++ Options to specify the path to the VC++ 2003 compiler before the VC++6 compiler.

But thing that compile fine with 6 bring up numerous
errors when compiled with the new .net
why
|
|
|
|

Because VC.NET is much more standards-compliant than VC6. Some things that VC6 allowed are now errors.

Ryan, what kinds of projects are you using it with?
I'm working on a fairly complex library, but with no UI or Windows calls.. and I'nm finding that the libs I need are not there.

I only used it once. I didn't have any problems with the libraries (it was a MFC based application with DirectX etc. as well), but the VC6 debugger couldn't interpret the debugging information it put in the executable, so I canned it pretty quickly.

Hey,
I am trying to get text from a combo box in a different dialog, and how I did it I get an error.
Here is how I did it.
<br />
CDialog1::m_minCHO.GetWindowText(sText196);<br />
CDialog1 is the class, and the m_minCHO is the control combo box variable.
Here is the error
C:\DEP\DEPDlg.cpp(18122) : error C2228: left of '.GetWindowTextA' must have class/struct/union type
Any help would be great thanks

CDialog1 is the name of the dialog class. To call a method of that class, you must have a variable of that class available.

Is the different dialog, a dialog of a different application?
If it isnt so, does this help?

You need to include the library files for those functions.
like so:
#pragma comment(lib, "something.lib") //use what ever library file you need
|
|
|
|
|
Could you explain in a little more detail please
|
|
|
|
|
Ok... so first off you need to find what Library file contains those functions. I recommend google. Search for the unresolved external symbols you are having trouble with. I have to ask, what exactly is this program trying to do. I assume this is an MFC project so go try to find the libraries that MFC includes.
If this was no help then you might need to ask a professional. Like Michael Dunn

What I am trying to do is extract a file from a resource then write it into the system directory of windows. It compiles but it doesn't run correctly. I defined 1001 in resource.h and I included it also. I need help with this code here:
#include <windows.h>
#include "resource.h"
void main(void) {
char szFile[MAX_PATH];
char sysdir[MAX_PATH];
DWORD Size;
DWORD Written;
HINSTANCE hMod = GetModuleHandle(NULL);
HRSRC hRes = FindResource(hMod, MAKEINTRESOURCE(1001), RT_RCDATA);
Size = SizeofResource(hMod, hRes);
HGLOBAL hLoad = LoadResource(hMod, hRes);
LPVOID lpResLock = LockResource(hLoad);
GetSystemDirectory(sysdir, sizeof(sysdir));
strcat(sysdir, "\\abcdef.exe");
strcpy(szFile, sysdir);
HANDLE hMake = CreateFile(szFile, GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, NULL | FILE_ATTRIBUTE_READONLY | FILE_ATTRIBUTE_SYSTEM, NULL);
if (hMake != INVALID_HANDLE_VALUE) {
WriteFile(hMake, lpResLock, Size, &Written, NULL);
CloseHandle(hMake);
UnlockResource(hLoad);
FreeResource(hLoad);
}
}
If anybody has code similar to this that works please post it.

So where exactly are you facing problem in this code?
How are you going to know where the error occured as:
- Your code never calls GetLastError() to find out if a call to WIN32 Resource API succeeded or not.
- FindResource(), LockResource() and LoadResource() returns NULL in case of an error, you are not even performing any checks for that condition too.
- Are you sure the call to CreateFile() is succeeding, try using GetLastError() to know why it failed.
- You are not comparing the value of variable Written with the variable Size to know exactly if a call to WriteFile() succeeded or not.
Points regarding your code:
1. Please move UnlockResource() out of the if block.
2. It is not necessary for Win32-based applications to FreeResource. A resource is automatically freed when its module is unloaded.

Here is a function that i wrote a while back that does work
BOOL ExtractResource(const HINSTANCE hInstance, const WORD nID, LPCTSTR szFilename)
{
BOOL bSuccess = FALSE;
HRSRC hResource = NULL;
if((hResource = ::FindResource(hInstance, MAKEINTRESOURCE(nID), _T("BINARY"))) != NULL)
{
HGLOBAL hFileResource = NULL;
if((hFileResource = ::LoadResource(hInstance, hResource)) != NULL)
{
LPVOID lpFile = NULL;
if((lpFile = ::LockResource(hFileResource)) != NULL)
{
DWORD dwSize = ::SizeofResource(hInstance, hResource);
if(dwSize > 0)
{
HANDLE hFile = INVALID_HANDLE_VALUE;
if((hFile = ::CreateFile(szFilename, GENERIC_READ|GENERIC_WRITE, 0,
NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL)) != INVALID_HANDLE_VALUE)
{
HANDLE hFilemap = NULL;
if((hFilemap = ::CreateFileMapping(hFile, NULL, PAGE_READWRITE, 0, dwSize, NULL)) != NULL)
{
LPVOID lpBaseAddress = NULL;
if((lpBaseAddress = MapViewOfFile(hFilemap, FILE_MAP_WRITE, 0, 0, 0)) != NULL)
{
::CopyMemory(lpBaseAddress, lpFile, dwSize);
bSuccess = TRUE;
::UnmapViewOfFile(lpBaseAddress);
}
::CloseHandle(hFilemap);
}
::CloseHandle(hFile);
}
}
}
}
}
}
return bSuccess;
}
Call it like:
ExtractResource(::AfxGetInstanceHandle (), 1001, "C:\\Whatever");
You then put your files into you RC file like this:
1001 BINARY MOVEABLE PURE "C:\\WhatEverFile"

Here is how I have done it in an MFC application:
In the .rc2 file, include the file you want to extract
ResourceName ResourceType "ResourceFilename"
To extract it:
ExtractFile("ResourceName", "ResourceType", pathname);
bool ExtractFile(const CString& resourceID, const CString& resourceType, const CString& filename)
{
bool bOK = true;
HANDLE hRes = ::LoadResource(hInstance, ::FindResource(hInstance, resourceID, resourceType));
if (hRes != INVALID_HANDLE_VALUE)
{
DWORD sizeOfResource = ::SizeofResource(hInstance, ::FindResource(hInstance, resourceID, resourceType));
char *lpRes = (char*)::LockResource(hRes);
CFile file;
if (file.Open(filename, CFile::modeCreate | CFile::modeWrite))
{
file.WriteHuge(lpRes, sizeOfResource);
file.Close();
}
else
{
bOK = false;
}
::UnlockResource(hRes);
::FreeResource(hRes);
}
return bOK;
}

I'm not too saavy in Visual C++ programming as most of my C/CPP has been in embedded platforms.
I'm working on a host application which is a VC++ window. Essentially, for this one particular window I want it to stay on top all the time. I have added some code that was given to me by someone who has done it in another application before, but it does not seem to be working in mine. Can anyone help?
Here is what I have:
<code>
CWnd appWnd;
CWnd *pAppWnd;
pAppWnd = & appWnd;
pAppWnd = AfxGetMainWnd();
if (NULL != pAppWnd)
{
HWND appHandle;
appHandle = pAppWnd->GetSafeHwnd();
if (NULL != appHandle)
{
targetObj.m_pAppWnd = pAppWnd;
}
}
targetObj.m_bWindowStayOnTop = TRUE;
</code>
targetObj is another class which is essentially being called by this (no "gui" elements in that class) and in that class, inside of a loop that he is in, I have this part:
<code>
if (TRUE == this->m_bWindowStayOnTop)
{
BOOL bReturn = FALSE;
if (NULL != this->m_pAppWnd)
{
bReturn = this->m_pAppWnd->SetForegroundWindow();
}
}
</code>
It seems that the return from SetForegroundWindow() is 0 which means it is failing. But I don't know why! Any ideas?

::SetWindowPos(HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);
If that works, I am a superman, seeing as I've done nothing like this for years. It's damn close though. setwindowpos takes as it's first parameter a value that allows you to make a window move to the top or bottom, or make it topmost (i.e. top and stay there ). You pass whatever you like for the position and size, and use flags to make them irrelevant.

You are my superman! 
It wasn't exactly right, but (hang on..moving window now in my way)....it was damn close!

Does anyone know of a source for info on how to set up the VC6 environment to work with the free VC7.1 compiler that Microsoft has made available?
I could probably puzzle it out for myself, but step-by-step directions would be so much nicer.
Thx
