Why don't you release the CString buffer?

Check this: How is SHBrowseForFolder() used?[^]

Error while compiling code

Hi,

I'm currently using Visual Studio 2005 to build my project.

The previous code that i have was written in Visual C++ 6.0. With the current development and tools, I already convert to project by using the Visual Studio 2005.

When i compiled my code, I got this error.

openssl.lib(v3_conf.obj) : error LNK2019: unresolved external symbol __pctype referenced in function _v3_generic_extension
openssl.lib(b_print.obj) : error LNK2001: unresolved external symbol __pctype

openssl.lib(rsa_sign.obj) : error LNK2019: unresolved external symbol __iob referenced in function _RSA_verify

I already check from the net. And I already ignore the lib : libcmt

Is there any thing that i can do to make it compile and works?

Thanks.

You should make it link, it already compiles.
You've to add the library wherein __pctype is defined in the Additional Dependencies line of the Linker's Input options.

Hi Pallini,
I already put the _pctype defined in the Additional Dependencies line of the Linker Input Option.

All error gone. But it create another error.

LINK : fatal error LNK1181: cannot open input file '_pctype.obj'

Do you have any idea?

Thanks

CPallini4-Nov-08 21:30

You shouldn't do that, you should add the library containing _pctype definition.
You cannot add a type as input file for the linker!
Hint for the library name: usually it has the same name the include file has (for instance, if you include, say mylibrary.h, then there are odds the library file name is mylibrary.lib).

Check whether you have included the right "ctype.h" file in all these modules reported by your linker.

LoadBitMap giving error

I am working on an mfc application and I am trying to load bitmap images into CRichEditCtrl Control for my chat application.
The problem with my code is that if i select only one bitmap(smiley) to send along with text it works fine but when the message contains more than one bitmap(smiley) the code gives error at LoadBitmap function call at some Attach function.

Please tell me how to resolve it.

Thanks In Advance.

What is the rationale behind the above? You're deleting a variable that isn't even a pointer.
