hello,
I set a value in registry. I checked the registry, the value was really set. And then I read it and try to print it. But the output is aways zero.
my code is:
char regValue[20];
unsigned long dataType;
RegOpenKey(HKEY_LOCAL_MACHINE,keyStr,&hkey);
dwRegValue = 100000;
RegSetValueEx(hkey,L"V1",0, REG_DWORD, (LPBYTE)&dwRegValue, sizeof(DWORD));
RegCloseKey(hkey);
RegOpenKey(HKEY_LOCAL_MACHINE,keyStr,&hkey);
RegQueryValueEx(hkey,L"V1",0, &dataType,(LPBYTE)regValue,&nSize);
RegCloseKey(hkey);
printf("\nregvalue: %d", atol(regValue)); //the output is: regvalue: 0
I don't know what's wrong with my code. could someone help me to solve the problem?
thanks in advance!

Since you're retrieving a DWORD value, change the above, for instance into:
DWORD dwRegValueBack;
then you have also to change
dadacncn wrote: RegQueryValueEx(hkey,L"V1",0, &dataType,(LPBYTE)regValue,&nSize);
into:
RegQueryValueEx(hkey,L"V1",0, &dataType,(LPBYTE)&dwRegValueBack,&nSize);
and finally
dadacncn wrote: printf("\nregvalue: %d", atol(regValue)); //the output is: regvalue: 0
into:
printf("\nregvalue: %d", dwRegValueBack);
Hope that helps

Just a comment, please use CRegKey class, which is optimized for this type of stuff!

Hi to all.
In my app I deal vith OnMouseWheel and then callOnVScroll with SB_LINEUP/SB_LINEDOWN nSBCode.
This is slow for my needs, how to speed up scroling on my mouse wheeling?
Thanks in advance!
|

|

what about X * SB_LINEUP/DOWN ?? Where X is the number of lines that you want to.
Greetings.

The SB_LINEUP/DOWN is a parametar which tells whether to scroll up or down, I don't think it has anything to do with speed.
I think I need to set bigger size of scroll line! Do it with SetScrollSizes!
Thanks for replay

The SB_LINEUP/DOWN is exactly what you say. And it comes from the SetScrollSizes, more or less 1/100 of the size.cy.
But what I said... is to get the WM_MOUSEWHEEL and multiply this SB_LINEUP with a coeficient. In order to make more than one line on each movement.
By default:
OnMouseWheel ()
{
if you are scrolling up
OnVScroll(SB_LINEUP, 0, NULL);
else
OnVScroll(SB_LINEDOWN, 0, NULL);
}
And what I am telling
OnMouseWheel ()
{
if you are scrolling up
OnVScroll( 3 * SB_LINEUP, 0, NULL);
else
OnVScroll( 3 * SB_LINEDOWN, 0, NULL);
}
with this you can use the normal Line size to Up/Down keys (for example) scrolling with accuracy, but do it faster with the mouse wheel. I you change the size of the line (another very good solution) then you will ALWAYS have that scroll velocity.
It is up to you and the needs of your project.
Greetings.

Thank you veOnVScroll( 3 * SB_LINEUP, 0, NULL);ry much, you're sure right there!
It's great advice and sure I'm going to do so! At first I didn't see that way.
Thanks one more time!

I'm doing this:
<br />
BOOL CMyView::OnMouseWheel(UINT nFlags, short zDelta, CPoint pt) <br />
{<br />
int pos =GetScrollPos( SB_VERT );<br />
if (zDelta>0) <br />
OnVScroll(3*SB_LINEUP,pos,NULL);<br />
else if (zDelta<0)<br />
OnVScroll(3*SB_LINEDOWN,pos,NULL);<br />
return TRUE;<br />
}<br />
When I scroll by LINEDOWN it's OK, but when I do the oposite (SB_LINEUP) it has no effect, scrolling it slow again.
Why?
Thanks!

Just handle the WM_MOUSEWHEEL message yourself - then you can scroll up / down by as big or small amounts as you like.
If you *don't* handle it, DefWindowProc will turn it into WM_VSCROLLs for you - which is making your life hard.

Hi friends
How to move a window using its mousemove function
thanx
-RisKhan-
|
|
|
|
|
You can use of MoveWindow.
|
|
|
|
|
do you mean you want to move your window by dragging it by clicking on anywhere on the dialog?
|
|
|
|
|
|
Handle WM_NCHITTEST and always return HTCAPTION.
|
|
|
|
|
Just a little aside note.
"Moving your window by dragging it by clicking on anywhere on the dialog" is OK in one particular case: it has no menu, no system menu, no maximize/minimize/close button, no scrollbars and is not resizeable.
Returning always HTCAPTION from WM_NCHITTEST message handler leads in the impossibility of using menus,... and all enumerated above.
A little bit better approach is to apply the trick only for the client area.
Here is an example:
UINT CMyDialog::OnNcHitTest(CPoint point)
{
UINT nRet = CDialog::OnNcHitTest(point);
if(HTCLIENT == nRet)
{
nRet = HTCAPTION;
}
return nRet;
}

Thanks Mr. Ovidiu Cucu
It works fine !!!
