Your code do not behave the way you expect, and you don't understand why !
There is an almost universal solution: Run your code on debugger step by step, inspect variables.
The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't find bugs, it just help you to. When the code don't do what is expected, you are close to a bug.

The downside of this solution:
- It is a DIY, you are the one tracking the problem and finding its roots, which lead to the solution.
The upside of this solution:
- You see your code behavior, you match it against your expectations.
secondary effects
- Your will be proud of finding bugs yourself.
- Your skills will improve.
You should find pretty quickly what is wrong.

I have two PCs with VS2008 installed. One PC belongs to me, the other is a loaner PC being used by remote access. If I create a simple smartdevice dialog application, my PC builds it fine. The other PC, when compiling stdafx.cpp spews the following (truncated to avoid insanity...). There are no seperate include dirs for headers, etc. I've compared project settings between PCs, etc. The only thing I found different is that the failing machine did not have the Windows 7 SDK installed.
Clearly I'm missing a header or a macro definition, but I don't see it. Ideas?

Smells to me like the sick machine is missing (or just can't find) errno.h which is where errno_t is defined. Without the SDK there may be a whole bunch of low level include files missing.
Happy hunting!

Sorry you being very silly for a programmer it isn't insanity it makes perfect sense
Look again at the error .. note the directories in particular
"c:\program files\windows ce tools\sdks\lync817_sdk\include\x86\stdlib.h"
There is nothing standard about and lets cover the basics
1.) The compiler is accessing files specific to some Windows CE SDK
2.) You are on a PC so you will need a SDK for Windows CE or the Compiler project settings are wrong
3.) The message is very clear what the problem is AKA it doesn't know what errno_t, it is an unknown type
4.) On a normal PC system errno_t is defined in the system file errno.h you use #include <errno.h>
5.) Being a system file the directories etc will be in the project settings as per note above.
Anyhow I am not a mind reader what you are doing but for some reason the compilation is using files in Windows CE SDK. Install the CE SDK if that is what you are doing or look at your project settings they are wrong. You could also just recreate the project from scratch on that machine it takes like 1 minute ... Create project from existing source is your friend.

Leon - yes, yes, you are correct. It is for a CE, Windows Embedded Compact, a Smart Device, and let's see what does Microsoft call them now? Hmm IoT or something. Note:
Quote: If I create a simple smartdevice dialog application, my PC builds it fine
All of the defaults are set up by VS2008, so I admittedly was hoping for a "oh, yeah, I've seen that before" response. Nothing magic here, this is a completely default mfc dlg app that is the default framework of an application.
This is an argument between VS2008 and I think the SDK, and years ago, I solved this. Just having a senior moment.

Hello,
Recently, we move from VisualStudio 2010 to 2013.
I use Ultimate Toolbox that I have compiled it with Visual C++ 2013 in a lib. It compiles and links without problem.
When I link this lib with my program, I get a link error: LNK2019 unresolved external symbol. With Visual C++ 2010, the link process was correct.
The symbol is the MonitorFromRect Windows function in COXToolTipCtrl:: CalculateInfoBoxRect().
We runs on Windows 7 Professionnal 64 bits. We compile on 32 bits Visual C++.
Is there a way to bypass this problem?
Thanks for any help.
Claude

Check your project settings to ensure the linker parameters are correct, and the library is included.

To elaborate on this suggestion, make sure that the linker uses the lib that you compiled with VS 2013, not the one that you compiled with VS 2010. The linker error may imply that it still sees the VS 2010 version. So, check the linker settings to see what search path it is using.

Hi Claude,
The reason of the problem is that the code uses the definition of MultiMon.h for function MonitorFromRect instead of using the native definition of this function coming from WinUser.h. Solution : remove line "include MultiMon.h" from OXToolTipCtrl.cpp to force the usage of WinUser.h definition for this function.

I open VS2015, click New Project, Select "Win32 Console Application"
Click OK.The dialog closes, then reopens.

Anyone seen this? Why can't I create a C++ console app?
If it's not broken, fix it until it is.

What dialog do you mean? I don't have dialogs in my console apps and I've written a few hundred of them.

Visual Studio install has got corrupted somehow, go to Control panel on the Visual Studio entry do a repair. It usually fixes the problem.

The error message already told what is the problem: just read it and check the code that it points out, in this case the else statement: that particular line is incorrect and needs fixing.

Also remove the semicolons following the right parens.
|
|
|
|
|

I mean the right parens on the lines with ifs.
The one on this line :
if(password=12345);
Will cause the printf to always execute.
