Aye, aye, aye! As stated above, GetLastError returns an integer. You then need to use this integer IN CONJUNCTION WITH FormatMessage to get a printable text string. If you have a look here, you can see an example of use for the two functions:

How do I incorporate my .cpp program, written in MS Visual C++(QuickWin.exe), into MS Visual C++ Windows App. Project?

I tried taking the .cpp file that I wrote it in and adding that to my project file list. I also put #include "stdafx.h" in the header of my .cpp program. When I build/compile the .exe Project file it says no errors, but when I try to execute it, nothing comes up on screen. Should I be linking the .cpp program file into another Project File(using Public)? Maybe there are too many Source files now that I added my .cpp program to the source file list? Maybe it is not possible to incorporate a QuickWin.exe program into a Windows App. Project? My books do not tell me how to do this. Can I just copy and paste the code into the Project .CPP file? Any help thanks. Confused | :confused:

What I should come up on the screen is a spreadsheet grid from the Project code and then I was hoping my program would run and ask the user a series of questions, it is a series of questions and numerical answers. Then it asks the user if he wants to quit the program and it exits. Both the spreadsheet grid(AppStudio) and the ABV.CPP program were created in Visual C++, but the spreadsheet grid is a Project and the ABV.CPP is a C++ program I wrote. I just want to incorporate that C++ program into the Spreadsheet Grid Project so I can show the user his data and maybe a chart. I would also like to have dialog created in AppStudio as opposed to my MSDOS black screen, white letters ABV.CPP program. Is that possible? Could I cut and paste my code into the project somehow or can I simply link the program to the project?

Mixing MFC framework with console application?

arnoldoh8-Sep-08 8:34

Hi,

I am trying to create a console program that uses MFC framework. More specifically.

1. The user would input commands/options/etc. into the console. Essentially a shell.

2. The shell will parse the command and send the information to a dll I wrote that will format the command and send to an external hardware.

3. The hardware does whatever and sends result/update, which is received by another thread and the message is formatted and sent up to a pipe.

4. I first wanted to use another console screen to display the message from the pipe, but I found out an application can't have more than 1 console screen. So I decided to use MFC to create a window to simply display the message. I have a class derived from CWinThread to do this, but I am not sure how to tie in the frame/document/view without using the document template. All the MFC documentation/references all state that I need to use document template, but since AddDocTemplate is member of CWinApp not CWinThread I am not certain how I can associate frame/view/document.

I am using VC++ 6.0 so I guess that means I am using MFC 6.0

Is what I am trying to do not possible? and should I try a different route like creating a separate application to display the messages on the pipe?

Thanks for any help.

Hi.. I'm using visual c++ v9.0 express. When I try to run the executable in other machine ( that doesn't have visual c++ isntalled and with framework 2.0) the program does not run. It says that the problem could be solved by reinstalling the program.
Can I solve this?
Thank you.

One more question

Product  //abstract         Creator  //abstract
+Method()                    +FactoryMethod()
  |                                |
  |                                |
  |                                |
ConcreteProduct<-------------ConcreteCreator
+Method()            +FactoryMethod()-----return new ConcreteProduct

In the demo code of Factory Pattern they use return to new

a ConcreteProduct object

<br />
Factory* fac = new ConcreteFactory();<br />
Product* p = fac->CreateProduct();<br />

what about using a member variabal of Creator to control Creator's behavior

like:

<br />
Product* p = new CreateProduct();<br />
//use p to initialize member variable Product* _p;<br />
Factory* fac = new ConcreteFactory(p);<br />

and use like "fac->_p->method()" to call different subclass member funtion

is it good or not to use a abstract class object as member variabal to control its behavior ??? Confused | :confused:

ParseCommandLine question

sashoalm8-Sep-08 4:17

I'm using ParseCommandLine to read command line arguments. I give the command line in debug mode with Project->Settings->Program Arguments. But ParseCommandLine thinks there are no args. I've seen the contents of m_lpCmdLine, and it correctly shows the args as I've given them.

So I step into ParseCommandLine, and it goes here:

void CWinApp::ParseCommandLine(CCommandLineInfo& rCmdInfo)
{
	for (int i = 1; i < __argc; i++)
	{
		LPCTSTR pszParam = __targv[i];
		BOOL bFlag = FALSE;
		BOOL bLast = ((i + 1) == __argc);
		if (pszParam[0] == '-' || pszParam[0] == '/')
		{
			// remove flag specifier
			bFlag = TRUE;
			++pszParam;
		}
		rCmdInfo.ParseParam(pszParam, bFlag, bLast);
	}
}

But it never enters the cycle - __argc is 0. Confused | :confused:

Interestingly, __argc is not a variable but a function, for argc it goes here

_CRTIMP int * __cdecl
AFNAME(__argc) (void)
{
        return AFRET(__argc);
}

And ParseCommandLine works in another project from which I copied/pasted the code.

What might be causing this problem?
Thanks.

The command line was like this
"C:\Path\File1.pdf" "C:\Path\File2.pdf" "C:\Path\File3.pdf" "C:\Path\File4.pdf"
so __argc should be 4

And CWinApp::m_lpCmdLine shows the command line as it should be. Why ParseCommandLine doesn't work when the command line correctly reaches CWinApp::m_lpCmdLine?

What happens if you try not using your CommandLineParser class
(just to test)...

CCommandLineInfo cmdInfo;
ParseCommandLine(cmdInfo);

I tested this by setting the Project Settings/Configuration Properties/Debugging/Command Arguments
to C:\Path\File1.pdf C:\Path\File2.pdf C:\Path\File3.pdf C:\Path\File4.pdf
and stepped into ParseCommandLine(). All four parameters are fine.
