pServer = session.GetHttpConnection(CStrDomain,nPort);
pFile = pServer->OpenRequest(CHttpConnection::HTTP_VERB_POST,CStrSuburl,Referer,1,NULL,"HTTP/1.0",dwHttpRequestFlags);
pFile->AddRequestHeaders(szHeaders);

I am usnig Visual Studio 6, to build a DLL. I want to change the target location where the .lib is generated, and I am unable to figure out what setting to change. Does anyone know?
thanks!

Hello Chintoo!
If you'r using VC++, you need to follow following steps :
change the output filename and path in Project -> Settings (Menu). and select your project and goto Library tab, and put the output directory you want.
If you'r using VB, you would get the save dialog box to specify the location for the DLL....

Its VC++. There is no Library tab, as it is a DLL project and not a static library.
thanks!
|
|
|
|
|
Then you'll get that option as 'Output file name' in 'Link tab' in project->Settings option.
-Malli...!

Hi ,
We all know windows system supports left mouse button drag and drop operation.
And we still can let our own application to support drag and drop operation.
My issue is can we get selected folders or files names before we release the left mouse button. That is to say, can we get selceted folders or files names during Drag&Drop's mouse moving process?
I want to use shell technicology to implement it. Unfortunately, I can get these informations only when I had clicked right mouse button or use left mouse button to move them to target folder,which supports drag&drop operation.
Any advice is welcome!
Thanks,
Well

During the Drag Enter and Drag Over notifications, you are able to determine what kind of data is being dragged; you might be able to take a peek at the data as well.
If using MFC, the OnDragOver handler gets a pointer to the COleDataObject for the dragged data. You might be able to call one of the Get*Data(...) functions off of that pointer.
However, note that you should NOT do anything too time-consuming during the drag over, or performance will be affected.
Peace!

James,
Thanks for you reply.
Maybe I had made a mikstake.
Here's drag-target isn't ourselves windows, so I cann't get Drag Enter and Drag Over notifications.
For example,User does drag&drop operation in two system owner folder(eg, C: source folder and D: target folder). Can we get draged data information when mouse is moveing in C folder region.
Maybe this issue can say it like this, Can we hook system's Drag&drop operation.
Thanks,
Welli

Hello Friends,
I have a question .
It is possible to call a second dll from the First Dll in VC++ application.
Case 1:
For example I a have dll called Sample A dll , then I have a second dll Sample B dll . It is possible to call Sample B dll from Sample A dll? All dlls are created using win32 dynamic DLL in VC++ platform.
Can any one tell me what are the merits and demerits of such a method ?
Case 2:
To avoid such a situation is it possible to include the functionality the second dll in the first dll, so that calling a second dll from the first dll can be eliminated completely.
Can any one tell me which of two Cases ie Case 1 and Case 2 is easy and more Reliable.

you make the dll or its already there? if you are making it , then why not include the "second" dll's functionality in the "first" ? or if you want to separate the functionalities you can still do. its always possible. just like you call the "first" dll from your application, you can do it in the same way to call the "second" dll from the "first".. get me ?

Hey all:
I wanted to have a basic service running on Windows XP. So, I went into Visual Studio (2005) and opened up the basic Windows Service template. I compiled, no problems, and went to the debug directory of my compile. As the template indicated, I typed myprojectname.exe /install . The install seemed to run fine, but, myprojectname did not appear as a new service. Can anyone explain this?
Thanks a lot!
Jim

Hell0 !
Did you check your tasklist (Taskmanager)? Is your service EXE runnig, is shown over there..?
-Malli...!
|
|
|
|
|
No, the tasklist does not list the program under it. I am definitely installing the programming as a service (or trying) as it does the whole, commit phase sucessful, etc.
Other ideas?

The MFC appwizard handles function pointer arrays very differently than the console appwizard. There are a variety of ways to establish a function pointer array with a console program. My favorite is:
void show1();
void show2();
void show3();
void (*pfun[3])() = { show1, show2, show3 };
This works great for a console program, but an MFC program objects saying you cannot create an array of functions, and then just to be frustrating, the error explanation says you can
create an array of pointers to functions.
I was able to create a function pointer array using typedef:
typedef void FOO();
FOO* pfun[3];
The MFC compiler compiles the above without errors, but it will not allow me to initialize the array. I get compiler errors from:
FOO* pfun[3] = { show1, show2, show3 };
and:
pfun[0] = show1;
pfun[1] = show2;
pfun[2] = show3;
and even:
pfun[0] = &show1;
pfun[1] = &show2;
pfun[2] = &show3;
How do I initialize a function pointer array that ?

What compiler errors do you get, exactly?
|
|
|
|

Console and MFC application are the same for these kind of things. This is just standard C++ and this won't change if you are doing a console app or a MFC app.
Post the exact error message and the complete definition of the different functions and maybe we can help. Maybe you are trying to use class member functions which doesn't have the same prototype.

The following code gives me a compile error C2440
'=' : cannot convert from 'void (__cdecl MyClass::*)(void)' to 'void (__cdecl *)(void)'
Header:
class MyClass
{
MyClass();
typedef void FOO();
FOO Show;
FOO *pfun[2];
}
Source:
MyClass::MyClass()
{
pfun[0] = Show;
}
In the error message, the only difference between the two types is the scope resolution operator.

Member function pointers are a bit tricky.
The class declaration should look like this:
class CMyClass
{
public:
void Assign()
{
m_FuncArray[0] = Fn1;
m_FuncArray[1] = Fn2;
m_FuncArray[2] = Fn3;
}
void Use()
{
(this->*(m_FuncArray[0]))();
}
protected:
typedef void (CMyClass::*MyFuncPtr_t)();
MyFuncPtr_t m_FuncArray[3];
void Fn1() { TRACE( "CMyClass::Fn1 called.\n" ); }
void Fn2() { TRACE( "CMyClass::Fn2 called.\n" ); }
void Fn3() { TRACE( "CMyClass::Fn3 called.\n" ); }
};
It's supposed to be hard, otherwise anybody could do it!

Wow, this looks really promising. I am sorry I did not see your post until now. I have an out of town job commitment that will not permit me to try this out until Friday. Thank you, Roger. I can hardly wait to try it.

There is nothing wrong with your declaration, but using a typedef for the function pointer type would make things more clear, e.g.
typedef (*MyFunctionPointer_t)();
MyFunctionPointer_t MyFunctionPointerArray[3] = { show1, show2, show3 };
There is no difference between a console app and an MFC app, it's still C/C++ synthax.
Hope this helps

Thank you everyone for your suggestions. This is still unresolved.
MFC app compiler should have the same c/c++ rules as the console app compiler, but it doesn't. Here is another example:
int TestArray[] = {3,4,5}; // MFC will only accept this within
// a function. MFC rejects this
// statement in a header file.
// Console compiles the line
// in either location.

Oh, yes it does. 
This is not dependant on whether you are building a console app or an MFC app.
Since you are DEFINING the variable in a header file you will get errors if that header file is included in more than one source file. The linker will complain about multiple definitions.
You can have as many DECLARATIONS as you want, but you can only DEFINE a variable in one place.
Probably in your console project you have only one definition since the header file is included in one source file only, but several in your MFC app since the AppWiz includes each header file in more than one source file by default.
Tip of the day: never define variables in header files.;)
If you write your statement at the top of one single source file then the variable will be defined only once. Declare it as extern in the header file to be able to access in from other source files.
If this doesn't clear things up for you, post again and describe how and where you declare your variable and why.

All my header files have the standard
#if !defined(gobbledygook)
#define gobbledygook
// definitions here
#endif
... supplied by Visual C++ wizardry to prevent double definitions. Anyway, I have also tried defining the function pointer array in the source file and the MFC compiler still objects to initialization. I wish you were right.

CastleIsle wrote: #if !defined(gobbledygook)
#define gobbledygook
// definitions here
#endif
When the next source file in the build process is built, the definition above is undefined. If you declare a class and plan to use it in more than one file, you have to include the header file with the class declaration in every file that uses the class in question, otherwise the class will be undefined.
Each source file is compiled separately and for each source file an object file (.obj) will be generated. The linker will link the object files together and build the executable. There is no mysterious way for the compiler to guess what was declared/defined when the last file was compiled.
(Sorry, but I consider this basic C/C++ knowledge...)

Yep, but that's because you're doing it wrong. See my previous post on your reply to Cedric about how to deal with arrays of function pointers to member functions.
