You need to use the TBS_DOWNISLEFT style, although this style may just be ignored by the control.

I've tried that and TBS_REVERSED , all combonations of both and it still seems to not be working.. Here is the part in the .rc file. Any ideas why this doesnt work?
CONTROL "",IDC_SLIDER1,"msctls_trackbar32",TBS_AUTOTICKS| TBS_VERT | TBS_TOP | TBS_ENABLESELRANGE | TBS_DOWNISLEFT | WS_GROUP | WS_TABSTOP | 0x400,207,23,21,116
Here is the OnInitDialog(), there is no other place i do anything with it.
BOOL CThisClass::OnInitDialog()<br />
{<br />
BOOL ret;<br />
ret = CDialog::OnInitDialog();<br />
<br />
altCtrl.SetRange(0, 3000);<br />
altCtrl.SetTicFreq(300);<br />
altCtrl.SetPos(3000);<br />
UpdateData(FALSE);<br />
<br />
return ret;<br />
}

Yes. Like I indicated, it may be one of those styles that the control ignores. I can neither confirm nor deny this, though.

Hi All,
Is there a way to know the reference to the calling function at runtime without using some flag variables? For eg.
<br />
void foo() {<br />
foobar();<br />
}<br />
<br />
void bar() {<br />
foobar();<br />
}<br />
<br />
void foobar() {<br />
<br />
if (calling function is 'foo') {<br />
bla... bla..<br />
} else {<br />
bla... bla..<br />
}<br />
}<br />
Thanks.

The only thing I can think of it to pass an argument to the foobar() function.

Thanks David. But maybe I did not put my question correctly. I have a library and I want to hide a function from direct calling by functions which are external to the library. Kind of like keeping it in private: section of a C++ class. But the problem is, I want the library in pure C and not C++. So, my library function 'foo()' should be able to invoke foobar() correctly. However, if an external function bar() tries to invoke it, the library should be able to correctly identify it and return appropriate error.
Appreciate your help.

Even with these new constraints, my suggestion will still work. All you have to do is choose a number to pass to the exported foobar() function that will likely not be guessed by others.

You are right. That is a Workable solution. Thanks David.

I'm not certain that you can hide functions in a library; hackers will find the name and arguments for it in the library ( but I might be wrong )
If the function is not "published" in a header file, a normal user will not call it.

Is it possible to store the images in one dll?
Here I would like to store some images into one dll.
And when ever I want I want to call them from that dll.
Is that possiable? Can anyone help me in this concept or any suggestion please.
Nice talking to you.

In your .rc file for the DLL project, add a line something like this for each image:
"MY_NAME" "IMAGES" "path\\to\\image.jpg".
Then load the DLL dynamically by using HMODULE hModule = LoadLibraryEx("path\\to\\dll", NULL, LOAD_LIBRARY_AS_DATAFILE); (Skip last parameter if you intend to execute code from it as well).
Then from your application call:
HRSRC hRes = FindResource(hModule, _T("MY_NAME"), _T("IMAGES"));
HGLOBAL hGlob = LoadResource(hModule, hRes);
DWORD dwResSize = SizeofResource(hModule, hRes);
void* pData = LockResource(hGlob);
By this point, pData is pointing to a byte array, which contains the data from the jpg-file. It's length is dwResSize.
I omitted all the error checking for brevity.

Call them for what ?
Can you help us by telling us what you want to achieve ?
One way to store images in a DLL is to include them in a resource DLL ( hint hint wink wink )

Here we are trying to store some giff images in the dll.
And would like to display them when ever we want.
I mean the functionality like messenger. The animations can be apeared in those images. Our application target is this.
Thanks for your help.

Create a Resource Dll as Suggested By Mr Jorgen!.. and you can use CEnBitmap: Derived From CBitmap[^] class by Dan.g. to dynamic display them..

Unfortunately, that class doesn't handle XP themes, so it would look really ugly in an XP GUI.

Indeed. Which is why I'm using the ChaNinja style.

Yikes!
My customers however mostly run XP as is. I doubt many of them know what a theme is. I do know though that they will be able to spot the difference between a seemingly square chunky thing and the rest of the GUI (the Fisher Price/Lego Duplo theme  ). The worst part is that I've got customers running Win98, Me, NT4 and 2000, so anytime I need to hack up a control, I have to give it two rendering routines.  (And I refuse to buy a third party class library as well. On a pre-XP box, I want things to look pre-XP. I guess I'm a stubborn GUI fascist  )

I recommend the brute force approach.
Since you want to put a bitmap on the button, why not simply include the text you want in the bitmap? (i.e. your bitmap has the text "Open" with the small folder picture next to it.)
