Thats exactly what I thought.

BUT, there are some cases in which an automatted format might be desirable. If you inserted a floppy in an unknown format into my MIDI-Keyboard, it would automatically begin formatting it, if you had pressed the "Save Song X" button.

They would state that in the manual, but the first time it happened, it did cost me disk 22 of Monkey Island....

Cheers,
Sebastian

Have a look at the function FormatEx in fmifs.dll

I think there is (or at least, was) some article/sample at Systems Internals (http://www.sysinternals.com)

The format is controlled by the dialog interface. That is, the user must click the OK button to actually begin the format—the format cannot be started programmatically.

Well, actually, it can. See my post. I have been using this func for ages in a program of mine. It even supports callbaks to a progress funtion (optional).

SHFormatDrive() will always present a UI.

The question, as well as my response, was regarding SHFormatDrive(), not FormatEx().

hi, im a mechanical engineering student and i've been given the task of calculating the second moment of area of three beams with different cross-sectional areas using the trapezium rule on c++ . i need the program to ask the user which cross-sectional area they want to calculate the SMOA for and use the corresponding data. the problem for me arises with the data for the heights and widths to be used as these are stored in txt files. the txt files contain a list of numbers: a single floating pt for the width, an integer, n, for the number of steps taken...which corresponds to the set of floating points which follow describing the height of the beam at these n points. i think i have to use an array to open and use the values, but one of the files has 20 values where the other two only have 10,(i.e.n=10 for two and n=20 for one) does anyone have any helpful hints for me? it would be very much appreciated!
thanks again

So your "width" text file has 20 values in it, and the "height" text file has 10 values in it. Is that correct? How about something like:

FILE *pFileHeight = fopen("height.txt", "r");
int  nHeight[10],
     x = 0;
while (! feof(pFileHeight))
{
    fscanf("%d", &nHeight[x]);  
    x++;
}
fclose(pFileHeight);

Hi,

Those all are having only header files, obj files, lib files, etc. I think those languanges are not supported library files[Dll's].

If any one given the information regarding this I appreciate it. Rose | [Rose]

passing pointer in thunking

Hi,

I have defined a call back:
typedef int (*GETHSPATTERNPPROC) (TCHAR **&, long&);
I am then loading the library:
DWORD hModSP = lpfnLoadLibraryEx32W("MyDLL", NULL, 0);
Getting the function pointer:
GETHSPATTERNPPROC hGetHSPatterns = (GETHSPATTERNPPROC)GetProcAddress32W(hModSP, "GetHSPatterns");
Then calling the method:
pchHSPaternNames = NULL;
lNumPaterns = 0;
CallProcEx32W(2, 1, (DWORD)hGetHSPatterns, (TCHAR FAR **)pchHSPaternNames, (DWORD)lNumPatterns);

In "MyDLL" I am doing:
lNumPatterns = GetPatNum();
pchHSPaternNames = new TCHAR* [lNumPatterns];
and here it fails.

What is going wrong????

before using parameters like you do, ensure it is not null...

DWORD hModSP = lpfnLoadLibraryEx32W("MyDLL", NULL, 0);
 
if (!hModSP) {
    GETHSPATTERNPPROC hGetHSPatterns = (GETHSPATTERNPPROC)GetProcAddress32W(hModSP, "GetHSPatterns");

thanks for the reply, yes i am having those checks in my code.
What I think is that the pointer TCHAR** pchHSPaternNames is not been passed correctly. Could you please confirm on that??
