Re: MSDN Jan 2002 with Visual Studio 6?

It is my understanding that from Jan 2002, MSDN will only intergrate with Visual Studio 7 and not version 6. If you want Version 6 integration you''ll need to keep October 2001 installed.

Welcome to the f***ing world of .NET. You have to stick with the Oct 2001 MSDN in order to use it with VC 6.

I always run a seperate instance of MSDN rather than use it from VS.

I installed new version of .Net last night,and MSDN was part of it,and many article is updated and changed.I think for VC++6 it is better to use old version of MSDN

This is a post I put round work today re this:

"Dear All,

Be aware that the new MSDN Jan 2002 collection does not work with visual studio 6 (F1 for example produces an error).
A quick investigation reveals that MS have changed their help system (again) - it now uses the:

C:\Program Files\Common Files\Microsoft Shared\Help\dexplore.exe

'Document Explorer' to launch the collection. Since this is significantly different from .chm files and suchlike it ain't
gonna work for VS6. Their may be a way to hack around this - the collection is nominally launched through VS
via an intermediary DLL (vshelpui.dll - i think) and checks the following key

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTML Help Collections

Of interest is this -

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTML Help Collections\Developer Collections\0x0409\0x039a1a660

which points at the chm collection for old MSDN installs and tells VC6 where to find it.. Basically MSDN *used* to tell
VS6 where to find it and how to launch it. MS couldn't make MSDN compatible with VS6 and/or couldn't be
bothered to produce a patch for VS6 to launch things correctly.

You can add a tool to the tools menu (really) that launches the new MSDN via the following path

"C:\Program Files\Common Files\Microsoft Shared\Help\dexplore.exe" "

And yes, it sucks

Ok, me again. Worked out the following. You can install BOTH MSDN Oct
and MSDN Jan 2k2 on the same machine - and they work with both VS .NET and VS 6. Yay! We're using a network install here so the total cost of having
VS .NET plus two MSDN 'lite' installs is about 1 GIG.

Works for me..

Simple question about DLL loading

Hi there,

I have a dialog wizard which I would like to perform its data integrity checks and its eventual task of inserting tonnes of data into various tables.

However, I need all the validations and eventual data insertions to be wrapped in a dll so other applications could use it as well.

How do I load this DLL into my exe wizard in Visual C++ and start using its member functions? what are the options and what is the best way of doing it?

thanks

From a simple DLL standpoint you would use LoadLibrary("DllName") and GetProcAddress(...) to get access to the functions and use them.

I would however consider writing your data access component as COM. More portable and easier to use.

Help! About structure alignment

I have a 4-byte data, it's content is:
bits 31-24 : pixel_data
bits 21-23 : unused
bit 20 : direction
bits 19-10: y_address
bits 9-0: x_address

So I construct a structure for it as follows:
#pragma pack(1)
typedef struct
{
unsigned int pixel_data : 8;
unsigned int unused : 3; /* must always be zero */
unsigned int direction : 1;
unsigned int pixel_x_address : 10; /* column */
unsigned int pixel_y_address : 10; /* row */
} FIFO_DATA_R_T;

it turns out the the pixel_data is at address bits 31-24, but unused is at bits 16-18.

How should I construct the struct? Confused | :confused:

many many thanx!

Hi Lucy. MS compiler has the following specific feature: bit fields are laid out from the least significant bit to the most significant bit. So your struct should be like:

#pragma pack(1)
typedef struct
{
unsigned int pixel_y_address : 10; /* bits  0- 9 */
unsigned int pixel_x_address : 10; /* bits 10-19 */
unsigned int direction : 1;        /* bit  20    */
unsigned int unused : 3;           /* bits 21-23 */
unsigned int pixel_data : 8;       /* bits 24-31 */
}FIFO_DATA_R_T;

This ordering is a compiler specific thing (Kernighan&Ritchie leaves it undefined, if my memory doesn't fail me).

Most probably the problem has not to do with iostream.h file, but with the file #included before it! Try swapping #includes to see what happens.

PS: IMHO it's advisable to have #include<iostream> instead of #include<iostream.h>: iostream (without the .h) is the latest version of the iostream library according to the C++ standard.

Problems changing the Print Setup dialog

A Wlasuk31-Jan-02 8:12

A Wlasuk

31-Jan-02 8:12

I have a need to add controls to the Print Setup dialog.

I did this via what I thought was the standard means:

- Copied the Print Setup dialog (PRINTDLGORD) to my RC file
- Created a Class based on this new dialog
- Used this new class (CMyPrintDialog) in place of CPrintDialog
- Added controls to the new dialog
- Used the following code:

CMyPrintDialog PrintSetup( TRUE,
PD_ALLPAGES | PD_USEDEVMODECOPIES | PD_NOPAGENUMS | PD_NONETWORKBUTTON |
PD_HIDEPRINTTOFILE | PD_NOSELECTION | PD_ENABLESETUPTEMPLATE );

PrintSetup.m_pd.hInstance = AfxGetInstanceHandle();
PrintSetup.m_pd.lpSetupTemplateName = MAKEINTRESOURCE( IDD_MY_PRINT_SETUP );

PrintSetup.DoModal();

All seems to work fine except entering text into a Edit Box on the new dialog appears to make the dialog repaint on each character. This is seem as:

- The Protrait/Landscape icon repaints each time a char is typed
- The cursor on the dialog repositions at the begining of the edit box on each char
- Takes a long time for each character and the hourglass appears.

I suspect I have left out a step.

Any suggestions?

Two questions:
What ID did you use for the edit box; make sure you're not re-using the ID of a control used by the system.
Do you have an EN_UPDATE or EN_CHANGE handler for the control? If so, what actions are you performing in it?

Hey,
I would like to get started learning about DLLs. I currently only work in MFC and C++ using VC++ 6. Does anyone know of any good tutorials for using DLLs with MFC apps.

.NET or not .NET? MFC is the question......

I wonder how it works. Let's say that I have a header file named MyHeader.h

then I want to use the #ifndef stuff... but how?

Like this(?):

#ifndef MYHEADER_H
...
#endif

if yes:
how does the compiler know that MYHEADER_H is my header... hmm... hope you understand..

#ifndef MYHEADER_H
#define MYHEADER_H
  
// ...header contents here...
 
#endif

This prevents a header's contents from being #included more than once.
