Another way is gethostname() .

I am having a problem with this function. It always returns FALSE and then CommDlgExtendedError() returns CDERR_INITIALIZATION.
MSDN says CDERR_INITIALIZATION is caused by low memory but I dont think this is the problem. I have rebooted my machine and other apps are able to display this dialog. Originally this code was in a ATL project for a MapPoint Add In. I have copyed it into a simple dialog based MFC app and still have the same problem.
can anyone help?
I have the following
OPENFILENAME ofn;
char szFile[512];
ZeroMemory(&ofn, sizeof(OPENFILENAME));
ofn.lStructSize = sizeof(OPENFILENAME);
ofn.hwndOwner = NULL;
ofn.lpstrFile = szFile;
ofn.nMaxFile = 512;
ofn.lpstrFilter = "All\0*.*\0TT Route Log\0*.TRL\0";
ofn.nFilterIndex = 1;
ofn.lpstrFileTitle = NULL;
ofn.nMaxFileTitle = 0;
ofn.lpstrInitialDir = NULL;
ofn.Flags = OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST;
BOOL b = GetOpenFileName(&ofn);
DWORD err = CommDlgExtendedError();

I did not find anything inherently wrong with your code snippet as it worked fine for me with no changes. A few things you *might* want to consider would be:
char szFile[512] = {'\0'};
ofn.nMaxFile = sizeof(szFile);
ofn.lpstrFilter = "All (*.*)\0*.*\0TT Route Log (*.TRL)\0*.TRL\0"; While they don't hurt anything, the statements that assign NULL and 0 to the other structure members are not necessary. ZeroMemory() has already handled that.
Also, check out MSDN article Q222003.

Haven't tried the actual code, but the one thing I notice is
ofn.lpstrFilter = "All\0*.*\0TT Route Log\0*.TRL\0";
lpstrFilter needs to de double NULL terminated, like
ofn.lpstrFilter = "All\0*.*\0TT Route Log\0*.TRL\0\0";

That fixed it. Thank you very much. Im suprised because that code was copied straight from MSDN

The is an implied \0 at the end of every string literal. So the string "All\0*.*\0TT Route Log\0*.TRL\0\0" actually end with three of them.

Hello:
I'm trying to do a proirity_queue like this:
#include < queue ><br />
using namespace std;<br />
<br />
struct stman{<br />
int age;<br />
double Height;<br />
char Name[255];<br />
}<br />
<br />
priority_queue <stman> myQueue;<br />
stman sMan;<br />
<br />
int main(){<br />
<br />
myQueue.push(sMan);<br />
<br />
}
The code here does nothing... but it explains the trouble in what i am, i can't save these tipe of struct into the queue, and order the priority based in the age of any instance of the struct.
The question is... someone knows how solve it???
Thank you in advance

I have a problem in changing the position of a checkbox control during runtime.
i created the checkbox control during runtime also.
i have tried using SendMessage
SendMessage(GetDlgItem(hwnd,IDD_PIN_BUTTON + (intPinChkCtr)), WM_MOVE, 0, MAKELPARAM( (WORD)rectDialog.left, (WORD)rectDialog.top++) );
during debug while watching the return of the GetWindowRect() it says that the controls top property has increased but it seems that the control has not moved its position in the dialog.
any suggestions?
thanks!

it is not very proper to combine such operations on the same line, especially when you do not / cannot know in which order it is executed...
in your :
SendMessage(GetDlgItem(hwnd,IDD_PIN_BUTTON + (intPinChkCtr)), WM_MOVE, 0, MAKELPARAM( (WORD)rectDialog.left, (WORD)rectDialog.top++) );
are you sure the rectDialog.top++ is executed before the GetDlgItem() funciton is executed ?
wouldn't it be better to write ++(rectDialog.top) , or better extract it before the line, then pass the value ?

thanks for the suggestion.
i tried it but it seems that the incremented top position was not kept.
during debug the top value would change but if i would be going back to the break point
again the previous top value was retained.
GetWindowRect( GetDlgItem(hwnd,IDD_PIN_BUTTON + (intPinChkCtr)), &rectDialog );
sizeDialog.cx = rectDialog.right - rectDialog.left;<br />
sizeDialog.cy = rectDialog.bottom - rectDialog.top;<br />
SendMessage(GetDlgItem(hwnd,IDD_PIN_BUTTON + (intPinChkCtr)), WM_MOVE, 0, MAKELPARAM( (WORD)rectDialog.left, (WORD)(++rectDialog.top)) );
it seems like the control was not keeping the changes from the SendMessage()

and what about SetWindosPos() instead of SendMessage() ?
