Hi,
I have defined a call back:
typedef int (*GETHSPATTERNPPROC) (TCHAR **&, long&);
I am then loading the library:
DWORD hModSP = lpfnLoadLibraryEx32W("MyDLL", NULL, 0);
Getting the function pointer:
GETHSPATTERNPPROC hGetHSPatterns = (GETHSPATTERNPPROC)GetProcAddress32W(hModSP, "GetHSPatterns");
Then calling the method:
pchHSPaternNames = NULL;
lNumPaterns = 0;
CallProcEx32W(2, 1, (DWORD)hGetHSPatterns, (TCHAR FAR **)pchHSPaternNames, (DWORD)lNumPatterns);
In "MyDLL" I am doing:
lNumPatterns = GetPatNum();
pchHSPaternNames = new TCHAR* [lNumPatterns];
and here it fails.
What is going wrong????

before using parameters like you do, ensure it is not null...
DWORD hModSP = lpfnLoadLibraryEx32W("MyDLL", NULL, 0);
if (!hModSP) {
GETHSPATTERNPPROC hGetHSPatterns = (GETHSPATTERNPPROC)GetProcAddress32W(hModSP, "GetHSPatterns");
if (!hGetHSPatterns) {
}
}

thanks for the reply, yes i am having those checks in my code.
What I think is that the pointer TCHAR** pchHSPaternNames is not been passed correctly. Could you please confirm on that??

consider a class say 'ABC'
i want to create a list holding only the ABC pointer locations
then is the below the correct way of declaring it :
CList<ABC*,ABC*> x;
one more question:
if i were to declare it as
CList<ABC,ABC*> y;
,then how is the second different from the first delclaration?

I don't know, and the MFC collections are confusing to use.
I think the first one is the only valid.
if you really have to guess about a declaration with MFC collections, then change to STL
std::list<abc> /// a list of ABC
or
std::list<abc*> /// a list of ABC*
it's much more clear.

That is one correct way, but certainly not the only way.
For the former:
ABC *a = new ABC(), *b;
x.AddHead(a);
POSITION pos = x.GetHeadPosition();
b = x.GetAt(pos); For the latter:
ABC a, *b;
x.AddHead(a);
POSITION pos = x.GetHeadPosition();
b = x.GetAt(pos);

that means the former Clist stores "the pointer locations"(and returns the pointer value) whereas the latter Clist stores the object itself(and returns the pointer of the object stored in the CList)!...is it?

Correct.

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.

Then you'll get that option as 'Output file name' in 'Link tab'in project->Settings option. Select 'Customize' option in category combobox...

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
