Do you have multiple copies of source/header files? Are you editing one copy, and then compiling a different copy into your exe? I did that once and experienced the same thing you are experiencing now. Check the file properties of the files you are having troubles in to make sure the complete path is the path you expect it to be.

hi dude
i rebuilt the applicaiton from scratch andhavebeen checking it as i go
some weird things still happening - using CFileDalog for example causes the code to get out of step!
I thought all this very srange so i uninstalled and reinstalle VS.net...same problem
Any thoughts?

Unfortunately no,
I still say go back and make sure you are actually building into your app the files you think you are. VC6 has an option that lists all of the files included in the project, I believe VS.NET uses the solution explorer to do the same thing. Check there for any "external dependencies". There it should list files that are being built into your app that are not part of the project.
Another thing you could try is using window's search to check your harddrives for any additional copies of the files that are out of synch. It could be that the compiler is grabbing one of them instead of the one you have open in the editor.
Without actually being at your computer that is all I can suggest.
Sorry if that is no help

I had the same problem, and I found out that the 'time-stamp' of some files were in the future (due to some file-sharing we have here at work) and caused
this problem.
The solution was to 'touch' all files and then rebuild the sources.
Hope it helps.

hi guys,
i have used unistd.h file in one of my header file , on compilation in VC++ it cannot find this file. can i use this in file VC++.
can anybody help me on this.
Cheers.

unistd.h is a POSIX header file. The Win32 API does not include POSIX functions. The Microsoft C run-time includes some POSIX-like functions prefixed with an underscore (e.g. _access() rather than access()). However some of these functions - particularly the _exec family - have somewhat different behaviour to the POSIX equivalent.
In the POSIX standard, the exec family load an executable image into the current process and execute it. To create a new process, you call fork. The Microsoft C run-time _exec family create a new process and execute the specified executable. The Win32 subsystem does not permit the POSIX exec behaviour.
Most of the MS CRT I/O routine equivalents can be found in io.h.

Any idea how to embed an exectuable inside another executable, and then from with in your program, call the embeded exectuable with out creating another process or wrting the embed exectuable to disk?
I have a C++ program (straight C++, not managed). It has some logic and then depending on a number of conditions, ShellExecute()s another exectble file (client.exe), which happens to be a .net file. Is there anyway that I can add this client.exe file as a resource of my C++ program, and then call the beginning of the code from within the C++ program, so I wouldn't have to extract the resource or create a new process
Please help

I've only seen one article on the Internet that explained how to run a program from memory (rather than from disk). Unfortunately I do not have the URL, nor do I remember what I searched for to find it.
For what reason(s) are you against running the program from disk? While I've never compared the two verbatim, I think that running from disk requires far less code than the other method.

I would like to convert members in a CStringArray to char[49]. What would be the best way to do this. I tried strncpy (with getting the length of the CStringArray member, but this didnt seem to work).
Thank you.

Try this:
char str[49];
strncpy(str, (LPCSTR)array.GetAt(index), 49);
you may replace strncpy with memcpy

When I compile and run this code it starts writing the files to a file but the problem is when it gets to a unicode character probably that has a 0 byte or something it stops processing the file. How can I get this Unicode into a file? What am I doing wrong?

Is there a way to save the printer & print options that a user selects from the CPrintDialog::DoModal() function into an ini file/registry entry? I want the user to be able to set up certain options when printing checks so that they won't have to change printers/trays each time they want to print a check.
Thanks,
Chad

Save the DEVMODE structure, device name, driver name, and port name from the m_pd member. You can then pass them to the CDC::CreateDC() function to create the printer DC that you use for printing.

Ok so I have the following code to save the printer options:
CPrintDialog pd(TRUE);<br />
pd.DoModal();<br />
DEVMODE *dm=pd.GetDevMode();<br />
theApp.WriteProfileBinary("CheckPrinter", "DevMode", (LPBYTE)&dm, sizeof(dm));<br />
theApp.WriteProfileString("CheckPrinter", "DeviceName", (LPCTSTR) pd.GetDeviceName());<br />
theApp.WriteProfileString("CheckPrinter", "PortName", (LPCTSTR) pd.GetPortName());<br />
theApp.WriteProfileString("CheckPrinter", "DriverName", (LPCTSTR) pd.GetDriverName());
Then to read it back:
DEVMODE *hDevMode;<br />
UINT nl;<br />
CString csDeviceName, csPortName, csDriverName;<br />
theApp.GetProfileBinary("CheckPrinter", "DevMode", (LPBYTE*)&hDevMode, &nl);<br />
theApp.GetProfileString("CheckPrinter", "DeviceName", csDeviceName);<br />
theApp.GetProfileString("CheckPrinter", "PortName", csPortName);<br />
theApp.GetProfileString("CheckPrinter", "DriverName", csDriverName);<br />
<br />
CDC* pDC=new CDC();<br />
pDC->CreateDC(csDriverName, csDeviceName, csPortName, hDevMode);
Does this look right? I am not familar with the Get/WriteProfileBinary functions and it didn't look like it was retreiving the information correctly when I debugged it.
Also how would I get the same options back into a CPrintDialog object so that a user could change the options?
And finally where should I call the CDC::CreateDC() function from the view class so that the CPrintDialog dialog won't be displayed again? Currently I have OnPreparePrinting(), OnBeginPrinting(), OnEndPrinting(), and OnPrint() functions extended in my view class.
Thanks,
Chad

dm is a pointer to a DEVMODE structure, so sizeof(dm) returns the size of the pointer - 4 bytes. Use sizeof(DEVMODE) and it should work correctly.

That didn't seem to work either, when I try to retreive the DEVMODE structure via:
<br />
DEVMODE *hDevMode;<br />
UINT nl;<br />
theApp.GetProfileBinary("CheckPrinter", "DevMode", (LPBYTE*)&hDevMode, &nl);
the string values have garbage in them, and most of the other paramaters are 0, or rather large values. Any other ideas?
Thanks,
Chad

What is the return value of GetProfileBinary? what is the value in nl?

dm is a pointer, so what you are saving here is the address of the DEVMODE structure, not the data in the DEVMODE structure.
theApp.WriteProfileBinary("CheckPrinter", "DevMode", (LPBYTE)dm, sizeof(DEVMODE));

That is the fun part. You have to rebuild the hDevMode and hDevNames members of the m_pd member of the CPrintDialog dialog. Remember that those are HGLOBAL handles to movable global memory objects, not pointers to a locally allocated memory block. Here is code that I use to do this:
LPDEVMODE pDM = pConfig->StringToDevMode(pConfig->DevMode);
int size = sizeof(DEVMODE);
HGLOBAL hDEVMODE = GlobalAlloc(GHND, size);
void *pV = GlobalLock(hDEVMODE);
memcpy(pV, pDM, size);
GlobalUnlock(pV);
delete pDM;
pDM = NULL;
size = sizeof(DEVNAMES);
size += (pConfig->Printer.GetLength() + 1) * sizeof(TCHAR);
size += (pConfig->Port.GetLength() + 1) * sizeof(TCHAR);
size += (pConfig->Driver.GetLength() + 1) * sizeof(TCHAR);
HGLOBAL hDEVNAMES = GlobalAlloc(GHND, size);
LPDEVNAMES pDN = (LPDEVNAMES)GlobalLock(hDEVNAMES);
pDN->wDefault = 0;
pDN->wDriverOffset = sizeof(DEVNAMES);
pDN->wDeviceOffset = (WORD)(pDN->wDriverOffset + pConfig->Driver.GetLength() + 1);
pDN->wOutputOffset = (WORD)(pDN->wDeviceOffset + pConfig->Printer.GetLength() + 1);
_tcsncpy((TCHAR *)((int)pDN + pDN->wDriverOffset), pConfig->Driver, pConfig->Driver.GetLength());
_tcsncpy((TCHAR *)((int)pDN + pDN->wDeviceOffset), pConfig->Printer, pConfig->Printer.GetLength());
_tcsncpy((TCHAR *)((int)pDN + pDN->wOutputOffset), pConfig->Port, pConfig->Port.GetLength());
GlobalUnlock(pDN);
CPrintSetupDialog dlg(this);
dlg.m_pd.hDevMode = hDEVMODE;
dlg.m_pd.hDevNames = hDEVNAMES;
if (dlg.DoModal() == IDOK)
{
pConfig->Printer = dlg.GetDeviceName();
pConfig->Driver = dlg.GetDriverName();
pConfig->Port = dlg.GetPortName();
m_EditSendTo.SetWindowText(pConfig->Printer);
pDM = dlg.GetDevMode();
pConfig->DevMode = pConfig->DevModeToString(pDM);
GlobalUnlock(pDM);
}
else
{
GlobalFree (hDEVMODE);
}
GlobalFree (hDEVNAMES);

The Print dialog is called from OnPreparePrinting(), so I think I would do it there. Have a look in MSDN[^] for more information. I have done this only in a dialog based app so I did not have the Doc-View framework at my disposal and have not had to worry about which function to override.

You were right I was just saving the address of the DEVMODE structure, no wonder it was reading back in garbage.
In the second part what are the pConfig and m_EditSendTo variables? And is the CPrintSetupDialog just a class you extended from CPrintDialog?
I will take a look at the MSDN docs and let you know what works for calling CreateDC().
Thanks!
Chad

pConfig is a pointer to a class that stores all my configuration data, the printer stuff is just a small part it. m_EditSendTo is an edit control that displays the selected printer and CPrintSetupDialog is a subclass of CPrintDialog.

Have a look at CWinApp::SelectPrinter, it may be better suited for you if you are using only one printer for all your documents (or have only one SDI document).
I have multiple documents that can be printed to different printers at different times with different formats, all without any user input, so I could not use CWinApp's built in printer support.
There is one thing I did miss telling you is the DEVMODE extra data (dmDriverExtra member). If you do not correctly save that data you may be loosing some information.
Otherwise the code you posted looks fine. You will just have to step through your code in the debugger to see if there is anything going amiss.

Actually the problem was reading in the strings with the GetProfileString() call I had:
theApp.GetProfileString("CheckPrinter", "DeviceName", csDeviceName);
which should have been:
csDeviceName=theApp.GetProfileString("CheckPrinter", "DeviceName", "");
so that was an easy fix.
Now the function is working fine, except when the program is closed. After I reopen the program I get an unhandled exception in COMDLG32.DLL (0xC0000005) Access Violation after the dlg.DoModal() call. When debugging the exception comes after executing: m_pd.hwndOwner = PreModal();. Here is the code from the MFC file DLGPRNT.CPP:
<br />
int CPrintDialog::DoModal()<br />
{<br />
ASSERT_VALID(this);<br />
ASSERT(m_pd.Flags & PD_ENABLEPRINTHOOK);<br />
ASSERT(m_pd.Flags & PD_ENABLESETUPHOOK);<br />
ASSERT(m_pd.lpfnPrintHook != NULL);
ASSERT(m_pd.lpfnSetupHook != NULL);
<br />
m_pd.hwndOwner = PreModal();<br />
int nResult = ::PrintDlg(&m_pd);<br />
PostModal();<br />
return nResult ? nResult : IDCANCEL;<br />
}
I did check the dmDriverExtra member and it was saved correctly.
I also tried using the SelectPrinter function by just replacing:
dlg.m_pd.hDevMode = hDEVMODE;<br />
dlg.m_pd.hDevNames = hDEVNAMES;
with:
theApp.SelectPrinter(hDEVNAMES, hDEVMODE, FALSE);
while it didn't throw an error, it didn't populate the CPrintDialog with the correct printer/values. This application has a MDI, and what I am doing is an attempt to setup a different printer for checks, cash receipts, and reports with out user interaction (once they have been setup of course).
Thanks again,
Chad
