Seriously? Did you read the docs to see what it does? Since the condition in the if test evaluated to false , that would indicate that GetWindowRect() returned zero.

i debugged it and i knew the returned value was zero, the question was why?

Calling GetLastError() would have likely told you why.

Oh, don't worry about, it's a decorative function...

Real men don't need GetLastError() ; what do you think CodeProject is for?

You're right: real women need GetHisLastError , while real men do need AdmitLastError .

Hi, I'm aiming to do something like instance a save as dialogue box have a user add input. Retrieve the file name and create the file based on the input. This is what I have so far:
OPENFILENAME _openfile;
ZeroMemory(&_openfile, sizeof(OPENFILENAME));
_openfile.lStructSize = sizeof(OPENFILENAME);
_openfile.lCustData = (DWORD)NULL;
_openfile.hwndOwner = GetFocus();
_openfile.lpstrFile = tmp;
_openfile.lpstrInitialDir = strcat(buffer, "\\Desktop\\");
_openfile.lpstrDefExt = ".xml";
_openfile.lpstrFilter = "Extensible Markup Language (*.xml)";
bool success = false;
success = GetSaveFileName(&_openfile);
HANDLE file = CreateFile(_openfile.lpstrFile, GENERIC_READ | GENERIC_WRITE,
FILE_SHARE_READ, NULL, CREATE_NEW, FILE_ATTRIBUTE_NORMAL,
NULL);
What I was wondering is if anyone knew of an example of how to do this on codeproject. I can't seem to find one. Thanks for anything you can suggest. Nicola x

I cant find a full example of using GetSaveFileName, and how I can then get the file name from that (which I assumed was supposed to be passed by reference back to me?)
Have you come across an article that might help? Effectively, All i want to achieve is
Click Save as button -> GetSaveFileName()
CreateFile(filename);
but I don't know how to get the file name from the dialogue.

Not sure I got you, anyway an usage example is here [^].

OMG I dispare! The reason it wasn't working is because I'm a moron....I mean because I wasn't adding .xml to the end of the supplied file name in the gui. Doh!

|

No wait, maybe it was something else....Here is the working code for any searching people:
char buffer[256]={""};
char tmp[256]={""};
tmp[0] = '\0';
GetEnvironmentVariable("USERPROFILE", buffer, sizeof(buffer));
OPENFILENAME _openfile;
ZeroMemory(&_openfile, sizeof(OPENFILENAME));
_openfile.lStructSize = sizeof(OPENFILENAME);
_openfile.hwndOwner = GetFocus();
_openfile.lpstrFilter = "Extensible Markup Language (*.xml)";
_openfile.lpstrFile = tmp;
_openfile.nMaxFile = sizeof(tmp)/sizeof(*tmp);
_openfile.lpstrFileTitle = "Save As ...";
_openfile.lCustData = (DWORD)NULL;
_openfile.lpstrInitialDir = strcat(buffer, "\\Desktop\\"); /*virtalis_diagnostic_info.xml");*/
_openfile.lpstrDefExt = "xml";
bool success = false;
success = GetSaveFileName(&_openfile);
DWORD error = CommDlgExtendedError();
HANDLE file = CreateFile((LPTSTR)_openfile.lpstrFile,
GENERIC_READ | GENERIC_WRITE,
FILE_SHARE_READ, NULL, CREATE_NEW, FILE_ATTRIBUTE_NORMAL,
NULL);
I hope this helps some idot n00b like myself!

In VC++,
When the Application is installed and opened for the first time and after performing Test in the panel and report(Report tab- it has been created based upon excel tab view) is viewed and while going back to the any test panel ABC.exe – Application error is coming and application gets quited once OK is given in that error message or Dont send error message is occureed.
It has been occurred only once. Again i have uninstalled and installed the application. I have executed the same sequence, but the error has not occurred for the next time. I have installed and uninstalled the application for 10 times, but the problem occurred only one. it is not occurring every time. i have stored all reports in the file.
In Report panel, i get the last test report and will be displayed.
Please give me the solution for this problem.

it is in MFC.
My application is causing problems now and again, but only after creating setup mode so I am having
trouble finding the cause of it.
"The instruction at "0x73dd1351" referenced at "0x00000004". The memory could not be "read".
above is message I receive when the crash happens.
Any suggestions on how I may go about finding this little blighter!
The strange thing is that I may try it 100 time and it works fine, or 9 times and get error on 10th.
There really is no pattern to it. The code is doing the same thing with the same hardcoded data
each time. Sometimes yeah but sometimes no

Hi all,
I have made a Regular dll using shared mfc dll in that dll i have made a generic class in that class i have made a function SayHello
in .cpp file
CString CMyClass::SayHello(CString str)
{
return (_T("Hello") + str);
}
in .h file
_declspec(dllimport) CString SayHello(CString str);
now i want to call this function in my clients application.
i have copied its .dll file and .lib file in applications debug folder.
and in properties\Linker\input\Additional Dependencies\..\Debug\MyDll.lib
now in code
HINSTANCE hDll = ::LoadLibrary(_T("MyDll.dll"));
now i want to call SayHello Function
How to do it?
Thanks in advance

Hi All,
I have a member variable of data type double.
Following is the variable
double m_Value [7] [3];
Now I have to do the declaration by using vectors.
so how I will declare it.
I have to Initialize it by 0 also..........
Thanks

Hi deadlyabbas,
const int ROW = 7;
const int COLUMN = 3;
vector< vector<double> > m_Value( ROW, vector<double>( COLUMN, 0.0 ));
Best Regards,
Jijo.

Thanks Jijo.
But the issue with this is that I am not able to make declaration and definition separately.
If I do it like this in .h file
vector<vector <double>> m_Value;
and in .cpp file I do this
m_value(10,vector(3,0.0));
It gave me an error which says
error C2064: term does not evaluate to a function taking 2 arguments

You should be able to do this using the constructor initialization list.
MyClass.h file
class CMyClass
{
private:
vector< vector<double> > m_Value;
};
MyClass.cpp
CMyClass::CMyClass() : m_Value(ROW, vector<double>( COLUMN, 0.0 ))
{
}
