CMapStringToString class

[ahammad]

I'm trying to use this calss to create a sort of data lookup program, where you type in some text, and the program returns the appropriate description.

I searched all over the net and there isn't a lot of documentation about this. I tried implementing the stuff written on the Microsoft website, but I can't seem to get the very first part to work:

#include <afxcoll.h>

The above gives me this error:

fatal error C1189: #error :  Building MFC application with /MD[d] (CRT dll version) requires MFC shared dll version. Please #define _AFXDLL or do not use /MD[d]

Honestly, this is the very first time I work with MFC and this function. I understand the theory behind the CMapStringToString function, but I have never implemented it. Also, I've been working with Visual Studio 2005 for a very short time (I switched from Visual Studio 6 last week).

Also if it is possible to show me an example of how to use CMapStringToString...I can probably figure it out on my own, but not before I get this #include problem out of the way.

Thank you very much.

Be sure WIN32 is defined in your project properties for the preprocessor.

When I defined the project, I selected the Win32 Console Application, if that's what you're referring to.

No.

You should create a Win32 Project.

When the wizard appears, DO NOT CLICK FINISH. Instead, click Application Settings. Select Console Application and MFC.

Now click finish.

Add your files and try a build.

Okay, I tried what you said and now the program compiles...thanks!

The other thing is using that class. Like I said earlier, I've never worked with it before. In any case, here is what I did:

CMapStringToString database();

This compiles fine as well. I still don't know how to use it properly though.

What I have so far:

database.SetAt(code, command)

Which is wrong, because code and command are arrays of strings, but the function SetAt takes in LPCTSTR, which, to be honest, I've never heard of. How do I go about doing this?

Sorry about the double post, but for some reason I can't edit my post anymore :/

Anyway, with regards to the previous post, I forgot to mention that when I try to change code and command from type string to type CString, The other part of my code, the one that reads in values from a file, stops working and starts reading in garbage numbers/letters:

Please enter the filename: test.cpf
00359900=00359960
0035AE18=0035AE98
00359900=0035E048
00359900=0035E048
00359900=0035E048
0035E188=0035E048
0035E188=0035E048
0035E188=0035E048
Data parsing has been completed
Press any key to continue . . .

I should be getting this instead:

Please enter the filename: test.cpf
<testcode1> = test command 1
<testcode2> = test command 2
<testcode3> = test command 3
<testcode4> = test command 4
<testcode5> = test command 5
<testcode6> = test command 6
<testcode7> = test command 7
<testcode8> = test command 8 
Data parsing has been completed
Press any key to continue . . .

Thanks in advance

I believe a LPCTSTR is a long-pointer-to-a-constant-TCHAR-string. Better to just call it a LPCTSTR.

From here on you need info on how to use MFC classes. I would start with Programming Windows with MFC by Jeff Prosise and go from there. You might find something by Googling CMapStringToString.

I don't have time to write a tutorial oin this class.

Thanks for the title of the book. I was looking for one yesterday but didn't find much. I'll go to the library later today and maybe I can find it.

Thanks again for your help, I appreciate it :)

I checked and it's available on Amazon.com.
