Hi Marc,
Remember, you don't have to abandon Unicode.
CString has methods to do most of the things those old char functions do,
but CString is generic.
If you truly need the char character type in a Unicode build, you can use
CStringA.

My C++ is rusty, about the last time I did C++ stuff was with VS7. So here I am with VS9, doing pure MFC/C++ (none of the CLR crap).
So, I've got a "lib" project and a console "test" project. The linker can only find functions that are inline'd in the header file. It can't find functions defined in the lib.cpp class!
What happened? And actually, why can't I find the lib.dll file? It creates lib.dll.embed.manifest, but no foo.dll!
In fact, I think I just answered my first question: I'm not referencing lib.dll in my test project, so it's only resolving inline functions. Why am I not getting a lib.dll lib? How do I get one?
Do I add a path to the Linker\General "Additional Library Directories" or do I add it under Common Properties "Framework and References"?
This used to be so much easier. 
[edit] Ummm. Why is the output going to a project in my solution that is excluded from the build and not even referencing the lib project? Why isn't it going to the folder specific to the project itself? WTF has MS done!!! [/edit]
[edit2]The output file property in the Librarian was using (OutDir) rather than (IntDir). WTF? Why would it do that? [/edit2]

Well I still use VC5.0, No problems with that there either. Works Nifty, Produces my code quite proficciently, The features VC5.00 misses are quite easily written by myself, I personally am not writing for the Chineese or Japaneese market, so why should I be bothered with the Unicode efford.
My advise is: 'Downgrade'

It seems it has been very long time since you did C++. There are two types of libraries in VC++ - Static lib and dynamic lib. "lib" project buids a static library and only produces a .lib file whereas "dll" project build a dynamic library and produces a .dll and .lib.

Because output file should go into *output* (OutDir) directory and not intermediate (IntDir) folder.

You should add the path in additional libraries directories and you should specify the import library at Linker -> Input -> Additional Dependencies.

I would expect each project to output to it's own Debug folder. At least, that's what it does in C#. It seems with a C++ solution, it sets the output to the first project created. I saw no place where I could change that setting once it was made.
Saurabh.Garg wrote: Static lib and dynamic lib. "lib" project buids a static library and only produces a .lib file whereas "dll" project build a dynamic library and produces a .dll and .lib.
Yeah, I finally figured out I wanted a static lib.

Adding the project as a reference also worked, though I'll definitely look at your suggestion.
Thanks so much for the feedback!

I don't do much C# so I am not sure how it sets the folder for a project but in VC++ it is like this.
"Configuration Properties" -> "Output Directory" : Sets the output directory for the entire project. By default it is set to $(SolutionDir)$(ConfigurationName) so the Release or Debug folder is created in the folder where solution file is located.
"Configuration Properties" -> "Intermediate Directory" : Sets the intermediate directory for the entire project. By default it is set to $(ConfigurationName) so the Release or Debug folder is created in the folder where project file is located.
Now if I have a solution with following organization:
FooBar
FooBar.sln
Project1
Project1.vcproject
Project2
Project2.vcproject
Project3
Project3.vcproject
I configure each project like this:
OutDir = $(SolutionDir)\Bin
IntDir = $(SolutionDir)\Temp\$(ProjectName)\$(ConfigurationName)
Note: If you want both debug and release binaries the add D to the debug configuration, otherwise this setting will only contain binaries from the last build.
Having said this, in VC++, you can configure path of each file produced separately. So if for some reason you wany PDB files in some other folder then go to "Configuration Properties" -> C\C++ -> Output files and set "Program Datbase file name" to any thing you want.
Also check out macros when setting a path, there are lots of useful folders defined as macros.
Setting project as reference works as well but well thats not how native developers do it

By the way sooner or later in the debug build you are going to encounter "LNK1000: Internal error during IncrBuildImage". To fix this install KB948127[^].

Hello,
I use EVC++4 for ARMV4I device. I have come across a situation where I find difficult to figure out few things.
I store data in a file like:
1+Oper 1+1+Dept 1+12+2+1.0+2+2.0+3.5+1+3.5
-------- ----------- - --------- ---------
Obj 1 Obj 2 S Obj 3 Obj 3 S-> # of objects stored of Obj 3 type
Now I am reading the file & I want data in a form where value of 1 from Obj 2 is against all the values of Obj 3. So,
1 Obj 3
Obj 3
For this I believe I should have a CArray in a CMap. The CArray can contain all Obj3 & value remains as the key of the CMap.
I am not able to make out how do I declare the CArray & the CMap. I am getting errors of CArray: no operator = ....
Can anyone help me create CArray & CMap respectively & also show how to add contents in the array & map rexpectively.
While reading file, I might need to access the saved CArray & add more if I come across the same number again.
I am using EVC so please provide only MFC or general C/C++ solutions - No std, ATL, etc. Evc doesn't support CArrayEx & CMapEx.
Help is highly appreciated.
Thanks
Terry

Well, part of the solution to your problem would be to serialize your CArray. To understand how to do that please have a look into Xavier John's Address Book[^]. If that isn't help you a lot please to MSDN page: Serialization in MFC[^].
Best regards,
Mihai Moga

Well Mihai, I also like Serilization, but EVC+ with +WinCE is giving a tough time with serialization. All proper code yet write & Read serialized objects is not supportive. So I have to take the long route. WinCE also doesn't support AfxAPI SerializeElements for CMap.
If ypu can give other solution, world be really helpful.
Thanks

Hi all,
I have an SDI type project i m also want to create another SDI type project inside it.
I want to call second SDI type project in First SDI type project.
How can both are working at same time and both are call from one project to another.
Please tell me how can i do this.
Thanks in advance.
IN A DAY, WHEN YOU DON'T COME ACROSS ANY PROBLEMS - YOU CAN BE SURE THAT YOU ARE TRAVELLING IN A WRONG PATH

Hi,
i used InvalidateRect();
Please look in the small code
Many thanx
Coc

This is the code from the doc:
CString CON_UPDATE_DEMODoc::ChangeText()
{
CRect MyRect(0,0, 100, 100);
CObject* pHint = (CObject*)&MyRect;
m_cstrAusgabe = " BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER \r\n\ BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER";
m_cstrAusgabe += " BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER \r\n\ BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER";
m_cstrAusgabe += " BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER \r\n\ BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER";
m_cstrAusgabe += " BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER \r\n\ BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER";
m_cstrAusgabe += " BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER \r\n\ BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER";
UpdateAllViews(NULL, 1, pHint);
return m_cstrAusgabe;
}
and this from the view:
void CON_UPDATE_DEMOView::OnUpdate(CView* pSender, LPARAM lHint, CObject* pHint)
{
CMainFrame *pMF = DYNAMIC_DOWNCAST(CMainFrame, AfxGetMainWnd());
CON_UPDATE_DEMODoc *pDoc = DYNAMIC_DOWNCAST(CON_UPDATE_DEMODoc, pMF->GetActiveDocument());
m_Rich.SetWindowText(pDoc->m_cstrAusgabe);
if (pHint != 0)
{
InvalidateRect((CRect*)pHint, TRUE);
m_Rich.SetWindowText(pDoc->m_cstrAusgabe);
return;
}
m_Rich.SetModify(TRUE);
CView::OnUpdate(pSender, lHint, pHint);
}

Since m_Rich is a CRichEditCtrl, why not just derive your view from CRichEditView? Or, you can derive it from CFormView and add a CRichEditCtrl to it. Otherwise, the way you rare going about this is all wrong.

i have a project from VC++ 6.
i converted it to vc++.net 2005.
when i rebuild the program an error appears : "string table error"
i have the last version compiled and its work fine.
do you have any idea why this error occurs?
sometimes 0 can be 1

I think you should ask this question in the NET forum.
