could you plz tell me in complete details how can i call matlab functions from a c++ program .
NOTE: ( i've already tried using engine.h but i got an error telling me" unresolved external symbol _engopen")

Did you include the lib that contains engopen?
Check this directory for some of the libraries that you need to link.
<matlab path="">\extern\lib\win32\microsoft\msvc60

i have created an SDI MFC app. How do i get it to check its own location on the hard-drive and spit back the path? IS there a path property for the executable?
thanks

You may find this code intresting
CString strTmp,strDirectory;
GetModuleHandle(NULL,strTmp.GetBuffer(MAX_PATH),MAX_PATH);
strTmp.ReleaseBuffer();
strDirectory=strTmp.Left(strTmp.ReverseFind('\\'));

Does anyone know what needs done to get the project built in Release mode.
Debug build is OK.

i.e. what setting have I forgot to change in Release mode.

Somehow it seems to be trying to link both the MFC DLL and the static MFC library. If you changed the setting 'Use of MFC' in Project Properties for the Debug build, change the Release build to match. Otherwise, it could be that some other static library you're trying to link with was linked with the static MFC library.

Thanks for your post. I did ensure that all project link to MFC in shared DLL, but now get the following errors:
Example error LNK2005: ___xc_a already defined in msvcrt.lib(cinitexe.obj)
Example error LNK2005: ___xc_z already defined in msvcrt.lib(cinitexe.obj)
Example error LNK2005: ___xi_a already defined in msvcrt.lib(cinitexe.obj)
Example error LNK2005: ___xi_z already defined in msvcrt.lib(cinitexe.obj)
Example error LNK2005: __amsg_exit already defined in msvcrt.lib(MSVCR71.dll)
Have you any futher suggestions for the above?

It's pretty much the same problem, only this time the library at issue is the C/C++ run-time. The setting you're looking for is C/C++ > Code Generation > Runtime Library.

Is there a simple way of making the Exe for my program get a different icon depending on whether it's a debug or release build?
I can change the icon the main dialog uses at run time without problem, but not the icon that the exe has in explorer

F*****G CodeProject 
I enter a message and hit Suhbmit, and the progress bar in Explorer goes to 100% and then just sits there!
Okay, as I type this in for the THIRD time...
Why not?
You can just add two different icons to your program based upon conditional compilation of the RC file.
Put a different one in there for release and debug.
I am pretty sure Explorer just uses the icon with the lowest numerical index.
Hope this one makes it into the forum...

Hmm, from experience I've found that compiler directives really don't work too well inside RC files
But I'll give it a try and see what happens

If you are using Visual Studio 6.0, it has an explicit tab for setting resource compiler settings.
See Project Settings Dialog : Resources Tab : PREPROCESSOR DEFINITIONS Edit Field
So, one of my projects, for exmaple, already has _DEBUG defined for the debug build.
Inside your RC or .RC2 file, do something like this
#ifdef _DEBUG<br />
1 ICON "MyDebug.Ico"<br />
#else<br />
1 ICON "MyRelease.Ico"<br />
#endif
and see if that works for you.
I would probably put it into the RC2 file, since the resource editor usually yacks on 'unexpected' preprocessor statements.

i want to create an array whose size is dynamic. Each node of the array should be an array of characters of length 20.And then i want to send this as an argument in a function.
This is what i have done.....
<br />
char *m_strTemp[10] = new char[count];<br />
After getting the value of "count" i start filling the array.
Now to send it as an argument of a function i declared the function as follows.
void CIdentifyDlg::SetVariable(char *str[10])<br />
{<br />
char *tempStr[10] = new char[count];<br />
tempStr = str;<br />
}<br />
The function is called as follows
<br />
SetVariable(m_strTemp[10]);<br />
This is giving error.
Can anyone please help me out. Hope my question is clear....

here you allocate an array of 10 char pointers and assign the char pointer returned by new to element zero (m_strTemp[0]). It's not an array of 10 (valid) pointers to char arrays.
nripun wrote:
char *tempStr[10] = new char[count];
tempStr = str;
same issue as above. Furthermore, in the second line you set the pointer tempStr to point to the same location as str points to (which is an array of 10 char pointers, where the first one points to a valid array). You do not copy the data pointed to by str into the array pointed to by tempStr.

which error?
I would use containers instead, either MFC containers or STL ones.

Why don't you use std::string (from the Standard Template Library) or CString (from MFC) instead ?
It will look like this:
void CIdentifyDlg::SetVariable(std::string* StringsArray, int nCount)<br />
{<br />
for (int i=0;i<nCount;i++)<br />
{<br />
std::string TempString = StringsArray[i];<br />
}<br />
}<br />

can you please tell me how to store numbers in a CString object??
|
|
|
|
|
Why do you want to store numbers ???? The problem is exactly the same as a standard string except you don't need to manage the memory yourself...
But if you need to send integers then use an integer array instead (int*) that is much more easy than store the numbers into char strings (and how would you do that ???)

This is what i want to do..........
<br />
sprintf(m_strTemp[i],"%d)\t%lf%% Match",i+1,m_final);
But m_strTemp is CString. So it gives the following error.
sprintf' : cannot convert parameter 1 from 'class CString' to 'char *'
|
|
|
|
|
Use Format() from CString, it will gives you exactly the same results:
m_strTemp[i].Format("%d)\t%lf%% Match",i+1,m_final);

Thank You very much ............

How about this?
SetVariable(m_strTemp);

I am programming a C++ MFC GUI application. During every execution of a for loop in my app I want the application to pause for about 1 second. How can I do this? I have been screwing around with WM_TIMER and SetTimer and KillTimer but I just can't get it to pause. Any help/examples would be a great help.
Thanks!
Lilli
