:(Please help me.
I use the SHSetFolderPath function to Assigns a new path to a system folder through its CSIDL.But it return fail.The source code as follow:
HRESULT hr = NULL;
HINSTANCE hLib = NULL;
typedef HRESULT (WINAPI *SHSetFolderPath(int,HANDLE,DWORD,WCHAR*);
hLib = LoadLibrary("shell32.dll");
if(hLib)
{
SHSetFolderPath lpfSHSetFolderPath;
lpfSHSetFolderPath = (SHSetFolderPath)GetProcAddress(hLib,(LPTSTR)232);
hr = lpfSHSetFolderPath(CSIDL_FAVORITES,NULL,0,L"E:\\TestFolder");
}
The "hr" return value is not S_OK,why?
Thanks;

 Hello,
I've got a problem and I hope you guys can help me out.
I want to use owner drawn Buttons. I use the CBitmapButton class and the LoadBitmaps()
member function. The bitmaps show round-shaped buttons.
My problem is, that I use a multi-color background for my application and want the parts of
the bitmaps, which should not belong to the button, make transparent.
Like if you create an icon with the IDE you can select the transparent color.
So that I don't see the whole rectangle.
I just want to know, how can I define a color to be transparent for a button?
For a normal bitmap to display is not a problem, but for a button I didn't found anywhere.
I am thankful for any help and ideas.
Paul.

Insert "Transparent Button" in the search engine of CodeProject you will find various examples.
Too many plans make the health badly...

I did so, but it did'nt help. The other either use others' classes or icons.
The others' classes don't seem to have solved the problem either.
It only looks like they do.

I can think of several possibilies, none of them will be fast.
If the dialog resource does not specify clip-children:
1) Draw the bitmap your self one pixel at a time, that way you can select and chose what to draw. If you use a DIB, this method can be very fast (see articles on DIBs at CP).
2) Scan the bitmap to determine where the edges are and then: create a clipping region (using thos edges), select it into dc and then just blit the image like normal.
If you want, you may be able to use the QuickFill algorithm (article at CP):
1) If you're not specifing clip-children: get a copy of the backgound image (via BitBlt, where you want to draw at), use the image as an argument to QuickFill inorder to fill the backgound (of the bitmap) and then blit the resulting bitmap.
2) If you're specifing clip-children: you'll have to get the backgound image
from the origanal bitmap (this will require some extra work if the images are not 1 to 1), use the image as an argument to QuickFill inorder to fill the backgound (of the bitmap) and then blit the resulting bitmap.
There are probably other ways to accomplish your goal. But the simpilist, and probably the fastest, is to use a DIB. By using a DIB and reading and writing one pixel at a time, you can also have transparent holes in your bitmap image.
Hmmm! A TransparentBlt that take a bitmap instead of a transparent color, sound like an article to me!
Well I hope that helps!
Good luck!

Did you try to use the debugger (F5 to start debugging and F9 to set/remove breakpoints) ? Because there you don't give us a lot of informations to help you....

Teach yourself database programming in 21 days.
I guess it will help you. It has all the info regarding database programming in VC++

May we access CMainFrame's members from CxxxView ?
Thanks in advance
|
|
|
|
|
You can use that:
((CMainFrame*)AfxGetMainWnd())-> ....
Hope this helps

Thanks in advance
|
|
|
|

Yes, you can use GetActiveView() like that:
CxxxView* pView = (CxxxView*)GetActiveView();
|
|
|
|
|
They appear these errors:
k:\paint\paintview.h(21) : error C2143: syntax error : missing ';' before '*'
k:\paint\paintview.h(21) : error C2501: 'CPaintDoc' : missing storage-class or type specifiers
k:\paint\paintview.h(21) : error C2501: 'GetDocument' : missing storage-class or type specifiers
Thanks in advance

Yesm you probably need to add #include "paintdoc.h" at the begining of your paintview.cpp file.
|
|
|
|
|
Normally, I do not need to add line 'include "PaintDoc.h"', why do we need to add this line now ?
More:
void CMainFrame::SetFColor(UINT nID)
{
CBitmap bitmap;
bitmap.LoadBitmap(nID);
HBITMAP hBitmapOld = ((CStatic*)m_wndMyDialogBar.GetDlgItem(IDC_FCOLOR))->SetBitmap(bitmap);
bitmap.Detach();
if(hBitmapOld != NULL)
DeleteObject(hBitmapOld);
CPaintView* pView;
pView = (CPaintView*)GetActiveView();
pView->m_clrBorderColor = m_clrFColor;
//SendMessage(WM_PAINT);
}
They appear an error here pView->m_clrBorderColor = m_clrFColor;
Thanks in advance

What is the error ?? Maybe because m_clrBorderColor is a private member of CPaintView ? It is a better principle to make all the member variables private and use Get/Set function to access the data
|
|
|
|
|
They both are public members.
I will try set and get functions.
Thanks in advance
|
|
|
|
|
They appear errors when my program is running.
Thanks in advance
|
|
|
|
|
Could you be more specific ??? It is simply impossible to help you with so few information... What are the errors, when did they happen.....
|
|
|
|
|
Please give me email, I will send the program to you.
Thanks in advance

Nope because:
1) I don't have visual studio installed here so I will need to dig into your code to find the errors without being able to compile it.
2) I don't have the time to correct the project for you. I can help you a little bit but don't ask me to do the job for you
3) You will never become a good programmer if whenever you have a problem you ask the other to do the job for you.
Some guidelines to help you:
Try to use the debugger which is a really powerfull tool and help you to see variables values and see where the program crashes.
Try to formulate correctly the problem. In general, some problems can simply be solved just by a good description of the problem (it becomes much clearer).
If you still have problems I suggest you to start a new thread in the forum (because it is no more related to the first subject) with a good descritption of the problem and eventually some source code (minimalistic otherwise nobody will read it)
