Hi
I was wondering if anyone knows the minimal code necessary to play a sound file of whatever sort (mp3, wave, whatever else...) at different speeds and/or in different directions (back or forward). Basically I'd like to make a super simple
turntable program... something with a "load" "play" and "stop" button and a slider that decides speed and direction of
your song...
thanks for any advice.

I'm looking for a thread safe alternative to the STL that comes with VS 7.1 I have reason to suspect that it's causing my application to blow up every once in a while.
Anyone know of any?

Can someone tell me how to check whether the Adobe Acrobat Reader is installed on a system (optional: which version?).
Should I just check whether the .PDF extension is registered or are there any special registry keys to look into?

this Key will tell where Adobe EXE is situated
HKEY_CLASSES_ROOT\Software\Adobe\Acrobat\Exe
and this key will tell about versions
HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\6.0
HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\Acrobat Reader\6.0
I know that the hack,but ................

Thank you!  I will use this method, maybe slightly enhancing it to different versions and/or checking for the full Acrobat package, too.

Check for the .PDF extension registration. Adobe is by far the most popular pdf reader, but it isn't the only one.
Acrobat 6 is such a pain that I'm now hoping someone ports xpdf to windows. In the mean time I open all pdfs on my unix machine. (mind xpdf sucks worse in most ways, but it loads so much faster that I can normally live with the loss of features. One day it might get those features.)

How can I access an HTML resouce "myfile.html" from an
MFC extension DLL?
I've tried two methods:
Downloading the address (res://extension.dll/myfile.html) [because it works in IE if you type it is]
and
Loading the library and attempting to get the resource from there but when I try to get the file name it complains about the name being a CString and not struct HRSC__* [meaning how could i call for myfile.html after parsing it out of the address [which is a CString]]

I had to go the route of loading the library and reading the resource file,
After loading it I got the HRSC from the FindResource with the type RT_HTML [this is why I never was able to find anything on google].

Maybe, after all it was difficult to find on google so maybe, if i can find time.

Hi
Let's say I have a pointer to a BITMAPINFO structure, and the structure holds information about an RGB bitmap in memory. Is there a way for me to directly write some string on top of the bitmap?
Currently I do it like this:
HDC hDC = CreateCompatibleDC(NULL);
void *pDIB;
HBITMAP hBmp = CreateDIBSection(hDC, pBmpInfo, DIB_RGB_COLORS, &pDIB, NULL, NULL); //pBmpInfo in of type BITMAPINFO*
memcpy(pDIB, pData, iWidth * iHeight * 3); //iWidth and iHeight are the width and height of the image, respectively, and pData is a pointer to the bitmap's pixel values, multiplied by 3 because it's RGB
SelectObject(hDC, hBmp);
DrawText(hDC, "This is a test", strlen(cstrStatus), &CRect(5, 5, iWidth, iHeight), DT_LEFT);
memcpy(pData, pDIB, iWidth*iHeight*3);
DeleteObject(hBmp);
DeleteDC(hDC);
So basically I first copy the bitmap's pixel values to a buffer created using CreateDIBSection, write the text on the DIB, and copy the DIB pixel values back to the original bitmap pixels' location. Is there a more efficient way to do this without copying the pixel values back and forth between the two buffers (something like writing the text directly to pData)? Due to the way the system is designed, my function must work on preloaded BITMAPINFO* input that resides in memory, not bitmap image files or other types of input. And because my system needs all the speed it can get, any tips on how to make the above code faster will be greatly appreciated.
Thanks!

nope. not if you're using the GDI text functions - they require DCs, and DCs require HBITMAPs and HBITMAPs require you to SelectObject them, etc.. if you want to get into 3rd party text-rendering engines, you might be able to avoid it, but that's probably a lot more trouble than it's worth.

How can I Highlight a CTreeCtrl Item, without set focus on CTreeCtrl?
 ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

Sounds like you need to make sure the tree control has the TVS_SHOWSELALWAYS style.
|
|
|
|
|
right! thank you. but when no focus, the color turns to grey, instead of blue.
|
|
|
|
|
Sure, but that's the way the control works. Highlight a file in Explorer, and give focus to another window - you get the same effect.

Hello,
I have trouble with the following few lines:
int CGoalsListView::GetItemFromPoint(CPoint point)<br />
{<br />
<br />
int nItem = 0;<br />
<br />
CRect rcItem, rcItemClient;<br />
nItem = 0;<br />
....
In the debugger, I see that as soon as the instruction for nItem = 0; executes, all locals change as though the stack just got slammed by something: nItem now equals some very large number, and the point is rewritten.
Any ideas about why this is occuring and how to fix it?
thanks,
JennyP
