this is a function <span style="font-size:small <span style="font-size:small ChooseProgram(PCHAR FileName)

<pre class="prettyprint CHAR FileName[MAX_PATH];
int ChooseProgram(PCHAR FileName)
{
OPENFILENAME ofn;
memset(&ofn,0,sizeof(ofn));
ofn.lStructSize = sizeof(ofn);
ofn.hwndOwner = NULL;
ofn.hInstance = hInst;
ofn.lpstrFilter = "Icona*.BMPTutti file*.*";
ofn.lpstrFile = FileName;
ofn.nMaxFile = MAX_PATH;
ofn.lpstrTitle = "Seleziona Licona:";
ofn.Flags = OFN_NONETWORKBUTTON | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;
GetOpenFileName(&ofn);

return 1;
}[/code]
<span class="x_hps so good.. in debug mode the stringstream rapresent corectly patch of icon, that i select.
but in <span style="font-size:small <span style="font-size:small ofstream scrivifile(<span style="color:#a31515; font-size:small <span style="color:#a31515; font-size:small <span style="color:#a31515; font-size:small "Setasti/settaggi"<span style="font-size:small <span style="font-size:small ,ios_base:ut);
not change, <span class="x_hps the file is not <span class="x_hps rewritten.

if i not use ChooseProgram(PCHAR FileName) function, the file <span class="x_hps
is written <span class="x_hps correctly <span class="x_hps obviously
<span class="x_hps without <span class="x_hps the patch
<span class="x_hps if i use ChooseProgram(PCHAR FileName) function but cancel operation of select a icon, the file
<span class="x_hps is written <span class="x_hps correctly <span class="x_hps obviously
<span class="x_hps without <span class="x_hps the patch
<span style="font-size:small <span style="font-size:small
anyone know <span class="x_hps what happens? xD <span class="x_hps makes me mad.. thanks all ^^<br/>
