Hi All:
I'm sure there are a number of you who have gone through this experience in the past, and rather than reinvent a method, I thought I'd ask first. Has anyone converted a large number of static libraries to DLLs using an automated method (or semi-automated)? Is there any advice you would give someone trying to do this for the first time? We have about 20 or so to convert, and ideally we would like to find a method that also allows us to use the conversion information to make *nix dynamic objects as well (but it not a hard requirement).
Regards,
-B

Yes (well, about 8)

Ummm - I created a new solution, with new DLL projects, copied the code across, hacked it around to add the necessary DLL exporting terms and rebuilt. It pretty much worked, IIRC.
Don't forget to use a a DLL based C runtime model across everyhting if you pass around ownership of dynamically allocated objects.

Also, I always use a macro to define the export type of classes and functions so that they can be used in both static and dynamic libraries easily.

I have a MFC MDI app in C++ and I'm rotating a CImage 90 deg., but trying to handle non-square images. I copy the CImage to a temp. buffer, detroy the CImage, create a new one with the new dimensions and write the pixels back into the new CImage. The problem is the display still is sized for the old image. I think I need to delete the DC and start a new one, but I'm not sure how. Any help would be appreciated. Thanks.

could you give a code snippet?

Here's some code...
if (nx != ny) {
nx2 = ny;
ny2 = nx;
m_image.ReleaseDC();
m_image.Destroy();
if (!m_image.Create(nx2, -(int)ny2, 32, 0)) {
fMessageBox("Error - CImagrDoc::Rotate()",
MB_ICONERROR, "Failed bitmap .Create()");
return;
}
p = (int *) m_image.GetBits();
}

I'll guess the next thing you do is changing the bits in the buffer P...
I'm not into C++ but with the following GDI-functions you maybe get the idea. I'll expect you have a handle to the source bitmap and a DC to the screen. Then use CreatecompatibleDC() to create an extra DC. Use CreatecompatibleBitmap() with the desired dimensions as the target bitmap. Now do everything you want with this bitmap and finally BitBlt() it back to the screen. Below a code snippet (not in C++, but i'll bet you can read it) that mirrors a area of the screen horizontally, to give you some idea:
hMemDC2:=CreateCompatibleDC(hdc)
dh:=int(h/2)+1
hbitmap2:=CreatecompatibleBitmap(hmemdc,w,dh)
hold2:=SelectObject(hMemDC2,hBitmap2)
stretchblt(hmemDC2,0,0,w,dh,hDC,x,y+h,w,-(dh+1),SRCCOPY)
bitblt(hDC,x,y-1,w,dh,hmemDC2,0,0,SRCCOPY)
DeleteObject(SelectObject(hMemDC2,hold2))
DeleteDC(hMemDC2)
Helps this?

My code was in the doc. class, so it looks like I will have to rewrite for the view to get the dc's.

This doesn't seem to be working and from what I've been reading I don't think this will work because CImage gets its own HDC. Do you have any idea how this can be done with the CImage class?
|
|
|
|
|
I just figured out that after I create the new CImage all I need to do is change the window dimensions. So just using this worked:
SetScrollSizes(MM_TEXT, pDoc->GetImageCSize());
GetParentFrame()->RecalcLayout();
ResizeParentToFit(false);
Thanks for the help anyway.

But you said you can't install Linux.

please help me write the same thing in c++ i am getting errors...!!

This just does not make any sense. At a minimum, you need to show the declaration of dfsnum, v, akt, and gw. You might also hint at what you are trying to accomplish. The less time we spend guessing, the better off you are.

That looks awfully like C++ anyway - C doesn't have methods of structs. I suppose set_user_label could be a function pointer in gw...

I am using VC++ (MFC application)6.0. In my project i use a dialog box in which 2 Edit boxes are there. The Edit boxes value changes dynamically during the program, but the Edit box do not update the value. The Edit box shows only the last value.
How can I overcome to this problem?
Please help me, i will be thankful for that.

How can an edit control's value change yet not change? To update an edit control, simply use:
m_edit.SetWindowText("This is my new value.");
...
CString str;
str.Format("I have %d", 5);
m_edit.SetWindowText(str);

Hi.
Maybe you can use
BOOL UpdateData(
BOOL bSaveAndValidate = TRUE
);
UpdateData(TRUE); means refresh the value of control to the variable
and UpdateData(FALSE); means put the value of the variable to the control.

if u call the SetWindowText() api, it will be update the UI display itself.
if u only modify the control's member val, u should call UpdateData(false) to force DDX to update UI

Hello,
I am trying to create a Windows service with the following WMI code from MSDN(except reading the credentials which I am hard coding):
Example: Getting WMI Data from a Remote Computer
- When I run this code as application, it runs fine. When I run this code as Windows service, it gives me "Access Denied" in ExecQuery().
- In ConnectServer(), when I pass NULL as username/password, as application it runs fine but in service it gives "Access Denied". Is there API or something to know the username and password used to start the service , so that I can use it in ConnectServer().
Please help.

Hi,
Yes the Microsoft sample may return 0x80070005 on Windows 2003/Vista/Win7. This Help and Support article addresses the issue:
WMI Sample in MSDN to remotely target a machine results in an 0x80070005 - Access Denied errorr[^]
