Just tried ShellExecute, which consequently is a pretty cool function.

I'm trying to run a program in a different directory to the one my MFC project is kept in.

I tried this:

ShellExecute(NULL,"open","d:\My Documents\Folder\ProgramA.exe",NULL,NULL,SW_SHOWNORMAL);

but it doesn't like the different folder.

You maybe need to escape the backslashes in your string:
ShellExecute(NULL,"open","d:\\MyDocuments\\Folder\\ProgramA.exe",NULL,NULL,SW_SHOWNORMAL);

My opinions may have changed, but not the fact that I am right.

yep that works but now the dos console opens up but doesn't initialise my ProgramA.exe. It just displays an empty dos window and hangs up.

I just tested with ipconfig.exe. It opens for a fraction of a second and closes.
Maybe it is in your ProgramA.exe?

ProgramA.exe is fine when it's run outside my MFC project.

The dos prompt works as it should when i call it explicitly but am getting problems when i call a program.

Also all windows programs are executing correctly.

I need ProgramA to work and hold until I have operated on it then i want to exit ProgramA and return to the MFC project.

I do not understand this sentence.
Do you want programA to start in a DosBox, perform its function and close the dosbox? This works on my computer.
Or do you need the dos box to stay open, to show the output of ProgramA?

My opinions may have changed, but not the fact that I am right.

the latter, as ProgramA requires user inputs and once these have been obtained, it can then perform it's function and be exited by the user.

Oh. I see.
From you first post ("It takes an input data file and outputs another data file.") on, I always thought of command line params.
For a test, I tried "more.com", (which also wants input) with ShellExecuteEx():

CString s ("C:\\WINNT\\system32\\more.com");
SHELLEXECUTEINFO SEI = {0};
SEI.cbSize = sizeof(SEI);
SEI.lpVerb = "open";
SEI.lpFile = s;
SEI.nShow = SW_SHOWDEFAULT;
   
BOOL err = ::ShellExecuteEx( &SEI );
if (err!=TRUE)
{
}

and it seems to work. If this does not help, maybe calling a Batch-file that in turn calls your program may help?

My opinions may have changed, but not the fact that I am right.

hyperterminal part2

20-Feb-03 0:32

hello @all,

a few days ago, i asked:

i would like to build a hyperterminal into a mfc program (after i pressed a button, the hyperterminal is to appear).

how can that be done?

i got the answer:

::ShellExecute(0,0,"hypertrm.exe",0,0,SW_SHOW);<br />

it functions perfectly (special thanks to M A V)! Big Grin | :-D

now, when the hyperterminal starts, i must make a few settings (select the com, give a name, baudrate and so on).

is there a possibility to load an old "test.ht"? i don´t want to make any settings at the beginning of the hyperterminal.

how can that be done?

thank you very much
sunny

Pass test.ht on the command line

::ShellExecute(0,0,"hypertrm.exe", "test.ht",0,SW_SHOW);

you may need to pass the full path to the test.ht file.

thank you for reply, it functions perfectly. Rose | [Rose]

i hope the last question to the hyperterminal:

is there a possibility that the hyperterminal window has full screen width?

thank you very much

thank you and i think i found it:

i use SW_SHOWMAXIMIZED to get the hyperterminal window has full screen width
and i think it works.

hi,

i'm using ado to connect to my database. now i want to retreive a date from the _RecordsetPtr. how do i do this? I also want to do this with a Currency...

my code:

<br />
COleDateTime	Date;<br />
Date = (????) pRecordset->Fields->GetItem("Date")->Value;<br />

Personally, I use the function VariantTimeToSystemTime to convert the returned VARIANT_T into a SYSTEMTIME structure which can then be used by COleDateTime.

this might sound stupid, but it doesn't seem to work...

my code:

<br />
_RecordsetPtr pRecordset;<br />
<br />
LPSYSTEMTIME time;<br />
VariantTimeToSystemTime((double)pRecordset->Fields->GetItem("Datum")->Value, time);<br />

It crashes....

That will be because "time" points somewhere invalid/undefined.
Try

SYSTEMTIME time;
VariantTimeToSystemTime((double)pRecordset->Fields->GetItem("Datum")->Value,&time);

That will work, unless the date/time stored is NULL.

I got another solution:

<br />
_RecordsetPtr pRecordset;<br />
<br />
COleDateTime date(pRecordset->Fields->GetItem("Datum")->Value);<br />

This works fine...

Thanks for your help,

You can build a COleDateTime from a _variant_t, the type that is returned from pRecordset->Fields->GetItem("Date")->Value. So, your code could look like:

COleDateTime Date(pRecordset->Fields->GetItem("Date")->Value);

How would one resize a CView derived view based on a LPRECT structure? I have tried using SetWindowPos() but with no luck.

Any help would be appreciated.

Thank you.

You need to resize the frame window that the view is inside.
