thanks, the problem with this software is that the png looses transparency after conversion.

Hi ! How can I convert a 32bit png image to 24bit png ?

I'm using VC 6.0 + sp 6. I'm working on a project for some time, but in the last week the ide got extremely slow (only when I'm working on this project). It hooks for 4-5 seconds when I want to open a file, or while I'm typing something. Have anyone experienced this problem ?

thanks for reply... but the function is SSCANF not scanf and unfortunately there is not a vsscanf version for it

Thanks, but I would like not to use a terminator (since it may be in the list of arguments)

I have a function fct(int a, format, ...) from this function I would like to call the function sscanf(s, format, ...) where ... must be the arguments passed to fct. Is this thing possible ?

I have a jpg file and a second jpg that is the transparency mask of the first. I want to create a png file from these two, with an alpha channel. Can anyone help me ?

I'm using vc6.0 sp6. I really don't know what is happening. The return seems to be as writing to a binary file, although I open "NUL" as text.

The following code: FILE *f = fopen("NUL", "wt"); retval = fprintf(f, "%.2f, 2000.0); returns 5 (so 2000. instead of 2000.00) Does anyone know the cause for this ?

The file I'm using is NUL. The complete code is: f = fopen("NUL", "wt") n = fprintf(f, "%d", 4); and is supposed to "write to nowhere" as I just need the number of charactes that have been written I don't have VC on this computer, so I cannot tell you the exact result, but it's about 3 or...

the code bellow: n = fprintf(f, "%d", 4); does not return 1, as I expected. Do you know the cause, and how this can be fixed ?

OK, I've found it: it's NUL

Does anyonw know a /dev/null equivalent for Windows? I would like to use fprintf to write to "nowhere", cause I just need the number of bytes that are written. I cannot use sprintf with a large buffer, since I want to avoid buffer overrruns. Please it's urgent.

Does anyone know why the _vscprintf function described in MSDN is not defined anywhere in vc 6.0 ? Does anyone know a better alternative to this function ? For instance, how can I use printf to print to a null device. I just need to find the result it returns (number of characters that have been...

Seems to work, but if I put a breakpoint in this function, then move from item 2 to item 0, it gets to the breakpoint 3 times. First 2 times pNMListView->iItem is still 2, and it gets to 0 the third time. I can do a workaround for this, but it's a bit stupid that it happens. It doesn't happen...
