question about linking to a static library - C / C++ / MFC Discussion Boards

I`m don`t think so, but some way to do this is to thru all your view using GetNetView, GetActiveview. Blush | :O

Is there anyway in Win32 or MFC, to retrieve the current directory of the running application?

Anytime, I run GetCurrentDirectory, I get the default windows directory or my desktop directory depending on the platform.

thanks Confused | :confused:

Use _getcwd ()

// GETCWD.C FROM MSDN

/* This program places the name of the current directory in the 
 * buffer array, then displays the name of the current directory 
 * on the screen. Specifying a length of _MAX_PATH leaves room 
 * for the longest legal path name.
 */

#include <direct.h>
#include <stdlib.h>
#include <stdio.h>

void main( void )
{
   char buffer[_MAX_PATH];

   /* Get the current working directory: */
   if( _getcwd( buffer, _MAX_PATH ) == NULL )
      perror( "_getcwd error" );
   else
      printf( "%s\n", buffer );
}

It is Illogical to define an inventor by his invention

Why Word ignores the message WM_VSCROLL? Is there an alternative to this method for making Word scroll down its contents?

hi all,
can you please tell me how to include the source code given int his site can be used in my application;)

i would like to experiment

I'm not sure what you're asking. Copy the class you want to use into your project directory, add it to the project (projectg/add/files from memory), and use it.

I am having problems using the DirectSound API. The problem is that sometimes my program attaches itself to the soundbuffer and does not release it. This prevents any other device from accesing the buffer.

Does anyone know what I am doing wrong??

Also, is there an easier way to stream audio?? I have DIS packets containing sound data that I need to stream. Is there a way to use the ActiveX Windows multimedia component to stream audio data that is not coming fram a file??

Please help me if you have any ideas....

Netmeisters,

I am having a great deal of difficulty doing something with VC++ which
should be very simple, and would appreciate your help. All I would
like to do is, create a static library and link an application to it
(as I said, it should be very simple...). The static library contains
C type functions, rather than C++ classes.

I create the library, we'll call it foo, by selecting New Project |
Win32 static library, and leaving the two options (MFC support and
precompiled headers) unchecked. Then I create two files, foo.h and
foo.c, in the library. The first just contains

void bar(void);

and the second
void bar() { }

This compiles OK, creating the file foo.lib. Now if I want to use
bar() in an application, I should just have to include foo.h and
specify a link to foo.lib. I do the latter by using Project | Add to
Project | Files, after which foo.lib shows up in the pane on the left
under Resources. When I compile the application, however, the include
file gets read (because there are no complaints about bar being
undefined), but the linker complains that bar is an unresolved symbol.

I have example code from a book showing how to do this, and the code
compiles just fine. Also, if I add my function bar() to the example
code, everything works as expected. If I declare bar() in my include
file, but define it in the example library, everything works fine. But
for some reason I can't define it in my own library; linking just
doesn't work.

There must be some straightforward way of making all this work, but
for the life of me I can't figure it out. This kind of thing is real
simple under Unix, don't know what is going wrong under Windows. Would
very much appreciate some assistance.

Thanks,

Matthew Fleming

Generally speaking, the issue has to do with the "name mangling" a c++ compiler imposes. I beleive if you use:

extern "C" {

Func1();
Func2();

etc }

or

extern "C"
{
#include <my_c_header.h>
}

you should get better results.

MSDN has some info on this if you want more. I have not dealt with this since way back in my 16 bits days, but I think that is what you are probably running into.

I think you need to add your library in Project|Settings...|Link in category Input in the Object/Library modules field.

I am again with the question refered before as COleDateTime.

I am using classes derived from CRecordSet to do ODBC connectivity. I want to pass null values to the database. The wizard have created variables for every table field. How do I pass null values to the DB especially DateTime.

This is urgent.. please.

Call CRecordSet::SetFieldNull. Pass field variable address as first param and TRUE as second.

Thanks..

I know this is more than likley a dumb question but... I have seen some dialog boxes where right below the menu they have drawn a simple straight line to devide the menu from the dialog box.. how do they draw a straight line?

Thanks,
Rob

Use a group box with no caption and make the height of the box smallest size.

There are no dumb questions, only dumb people!

how can I send to a MFC called "A" information of a "mthing" to another MFC called "B"???
For example, I want to transmit to "A" a name stocked in "B" when I pushed a button "OK"
thanks...

whats an MFC?
an MFC window? an MFC program? an MFC Dll? an MFC Class?
if you want to transfer data between applications you can use any of the various IPC methods. The simplest way is to send a WM_COPYDATA message.

hi!!!
thanks to answer to my question!!!
I want to send parameters from a dialog Box "A" to a Dialog Box "B"....

You can create a new member variable for your CbDlg dialog box(example type CbDlg name m_dBdlg)in CaDlg class then use the class wizzard assign member variables to your drop down boxes, edit boxes etc.. now within dialog box "a" you can for example use m_dBdlg.m_editbox() etc..

Hope this helped. Not sure if im being very clear.

Rob

thanks!!!!
Link you later!!!
