i think the problem is on flag "open". u r trying to run a file that u'd already opened in the same process.
u can play with ShellExecuteEx. but i strongly recommend u to use CreateProcess(...). its never let me down.

Hi.
This is my first time using anything to do with Matlab, so I apologize if this is a stupid question, but I would really appreciate any suggestions:
I am trying to incorporate a Matlab-created dll into some VC++ code (either VS6.0 or VS.Net – right now neither works). I can get the code to compile, but when I call a Matlab function
mxArray* pArray = mxCreateDoubleMatrix(nRows, nColumns, mxREAL);
I get the following errors:
VC6.0
Shuts the executable down without any error
VC++.Net
“An unhandled exception of type 'System.IO.FileNotFoundException' occurred in system.windows.forms.dll
Additional information: File or assembly name ________, or one of its dependencies, was not found.”
I do not have Matlab installed on my computer, but I have compiled and ran these programs on a computer that does with exactly the same results.
Does this sound familiar to anyone? I have seen references to a Matlab Add-In for Visual Studio – do I need to install this?
Any help would be greatly appreciated. Thanks.

I have no idea what happened, if I did it, or how to fix it. All of a sudden, when I began to run my program using ctrl f5, the program will build and then I will get a dialog box with an ICONSTOP and the title "Microsoft Development Environment" and it has the text "Unable to start debugging. The Machine Debug Manager is disabled". It doesn't run the program!!!
Well how in the world do I enable it again???

The Machine Debug Manager is a service that is running on your computer. It must be enabled and running in order for debugging to work.
To re-enable it (in Windows XP), right-click on My Computer and choose 'Manage'. In Computer Management, expand the 'Services and Applications' node, then click on 'Services'. (An alternatice to this is to use Start->Run and type 'services.msc' on the execution line)
From the list of services, browse until you find 'Machine Debug Manager'. Right-click, choose 'Properties', and set the Startup type to 'Automatic'. Then click Ok, and right-click on the service name again. This time, choose 'Start'.
Now the service is running and is automatically started when your machine boots up. The debugging should work again.

Is there a macro to declare a variable as intentionally unreferenced? Something like:
int nDontCare = foo();
UNREFERENCED_VAR (nDontCare)
I prefer not to take the cheesy approach, eg: VERIFY (nDontCare == nDontCare).

why declare a variable if you don't intend to use it ?
you could do something like :
(void) foo();
or simply :
foo();

True, there are several alternatives. But I may intend to use the result at a later point in time and was wondering if there was a standard way of marking the return value as unused.

Does UNUSED() (defined in Afx.h) do the trick?

Gak! It seems to be defined for release builds only. How vexing.

I'm using a HTML dialog and I want to be able to hit one button, HTML or regular, and have it call C++ code and open a web site in the dialog box. I can currently make a HTML button either call the website or run the C++ code.
I think that I would rather have a regular dialog button, so it doesn't dissappear when the website is pulled up. Any help with the call to open a web site with VC++.net code would be great. I'm running Visual Studio.net Pro.

Currently I'm developing an application with "command window", which consists of two edit boxes: for user input and program output.
As I've been using WIndows 98...Me...2000 everything was all right. But recently I've moved to Win XP, and found out that it's impossible to rpint anything in output window.
I'm using SetWindowText() for output.
Any ideas?
|
|
|
|
|
Window handle of output window is valid on the moment u try to settext here?
|
|
|
|
|
Yes, it's valid.
Moreover, there're some kind of output: a line of several blanks appears instead of my text.
|
|
|
|
|
hm. first heraing about it. what kind of text r u triing to set?
maybe regional settings?

Do you mean if they connected through Windows Terminal Services? If so, have a look at WTSEnumerateProcesses().

hi
in the following code:
PRINTDLG pd;
AfxGetApp()->GetPrinterDeviceDefaults(&pd);
DEVMODE FAR *pDevMode=(DEVMODE FAR *)::GlobalLock(pd.hDevMode);
...
DM_PRINTQUALITY of lpDevMode->dmFields is set but dmFields&DM_YRESOLUTION is not set. why?
(lpDevMode->dmPrintQuality,lpDevMode->dmYResolution) is (-3,0)!!! why?
i can print without any problem in applications like MS_Paint. how do such applications calculate the printer resolution? they may also bring up the print preview environment with no problem.
what's the reliable way for calculating printer resolution which works with all printers?
HP LaserJet 4 examined and it's ok with this method (600x600)
HP Deskjet 3650 examine and it's not ok (-3,0)
what's the problem and how can i resolve it?
what's wrong with the method?
thanx

"Active window" is too vague a term to provide a specific answer for. Is it a dialog, a control on a dialog, a view, a control on a (form) view, or something else? Please explain further.

if i understood u well:
try following:
HWND hwnd = FindWindow(...); // or sequnce of call of FindWindowEx
// to know a valid window's tree use spyxx from the vs tools.
SetWindowText(hwnd, "SomeText"); // This code change captions.
// or to fill up an edit
SendInput(...)

Are you talking about the desktop's background (i.e. wallpaper)? If so, check out SystemParametersInfo(SPI_SETDESKWALLPAPER, ...).
