Having created lots of mickey mouse applications using the wizard, as well as trying out examples in the half dozen fat books I have bought, I am nowhere nearer to understanding the what where and how of how to structure an application. I have nice examples of how to output text in a window, how to draw lines, OR how to read in data from the keyboard, but there seems to be Jack Beep around on how to tie any two of these obviously mind-boggling concepts into the same app.
What I want to do is read and process data from a binary file (done, that was easy) and then use some of that data (actually x-y positional data) to write shapes to the window. Any help or ideas much appreciated.

This sounds like a good job for an SDI application. Read the data into the document. The document then notifies the view that new data needs to be rendered. In in the view, ask the document for the new data and render it accordingly. Look at the MSDN's Scribble tutorial.

Scribble, what a great learning tool. When I started with MFC (had used OWL before) I printed out the entire tutorial, followed it from start to end, and then started adding my own stuff. CP was not around at the time, so I don't think I could have figured out so much about MFC without it.

"Read the data into the document" - done. Because it's binary, I thought it needed to be read in and processed byte by byte. To do this I wrote a routine :
BOOL CMyDoc::OnOpenDocument(LPCTSTR lpszPathName)
{
if (!CDocument::OnOpenDocument(lpszPathName))
return FALSE;
// lots of my code to convert various doubles, ulongs, ushorts etc into physical numbers and attributes //
// all data processed, ready for display//
//Now we're stuck. //
}
Now, the problem I have is, *how* do I pass the data to - and to *which* routine - in order to paint, say, a box on the screen, using that data? Automatically, i.e. no mouse input, no keyboard input. I don't want to draw using the mouse, and it is not a dead text file that I am reading. The whole concept is an automatic process, in which the user is prompted for a path, and then the application processes a bunch of different files, mostly binary, and then *should* output a simple graphical representation of some mechanical items on the window, based on the data that was processed.

Handle the OnDraw function in your CView based class. From OnDraw, you can call GetDocument() to retrieve a pointer to your document.
CMyView::OnDraw(CDC* pDC)
{
CMyDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
pDoc->GetDataUsedToDrawStuff();
if (pDC->RectVisible(blah))
pDC->SelectObject(brush/font/pen);
pDC->FrameRect(blah);
pDC->TextOut(blah);
etc...
}
 Pssst. You see that little light on your monitor? That's actually a government installed spy camera. Smile and wave to big brother!

For some unknown reason my system has changed language for error messages. When I call CException::GetErrorMessage( buf, maxSize ) I get error messages in German, which might not be too bad if I knew German, but I only speak American English. While I admit this makes me less interesting as a person, it makes my error reporting useless. Historically speaking, this language change is recent, perhaps following the use of someone's submitted article on this site. My question is, how do I change the default error message language back to English?
Anyone... anyone?

Wouldn't that be in the Regional Options applet in Control Panel?

No..., that's the first think I checked and it is set at American English, which of course is why the rest of the OS is in English...

I have a fairly small project (main window with about 6 dialogs) that I have built using VC6. Our marketing dept. has decided that we need to make it a multi-language app. He wants to be able to give a text file to someone and let them translate from the english text to their language and give the file back to us. Our program would then read in the translated text and replace each instance.
It sounds like a real nightmare. Are there better ways to go about this? It's a technical app with references to things such as Ethernet switches, controllers, ... so I don't know if any of the auto-translation products would be able to handle it correctly.
Also - how to people deal with the text field lengths (static boxes, group boxes, buttons, ...) when the translations end up needing more space?
Thanks so much for any help you might be able to provide.

2 things :
first technically, doing this is simple, create a resource DLL for each language and load it dynamically when the application starts; you will have to translate each version of the RC file; I don't think there's an easy way to make sure that each dialog layout is ok for each language but to test them.
for example :
...
m_hInstDLL = ::LoadLibrary(_T("English.dll"));
...
AfxSetResourceHandle(m_hInstDLL);
...
second, translation of technical terms should be precise, you should contract that to a professional.

Hello,
Earlier I have plans on releasing such translation system as commercial, but thought that nobody need it at the era of .Net  I'm using it in my file comparison software (http://www.grigsoft.com/), you can check results. I can share it with you, to see how easy it can be included in new application. Please contact me personally at support--grigsoft.com

There are some examples of multi-language applications on CP... just have a look at them.
Don't try it, just do it!

Indeed.

Yes. It involves changes to the project's .rc file. Search MSDN for internationalization articles.
I realize you couldn't do this, but for my company's product, we create the initial DLL in English and then ship the DLL's source code to IBM for translation. They take that and create a DLL for each additional language. The customer then only gets the DLL for their locale.

I increase their width by 65%. They might be a little too wide but that's better than being any too narrow.

Thank you very much for the replies. I will try to convince our marketing dept. that using a text file may not be the best way to go. Actually, I have to convince them - I'm a dead man if I can't .

If it's a one-time endeavor, or a small-scale application, a text-file solution is not that bad. However, I would first try and convince them top do it right. Be prepared and bring lots of ammunition (e.g., references, examples) to the table.

Am i understanding this correctly?
We use a Node to represent the very first first tag in the document. After that we use elements for all subsequent tags. Is this correct?
If so, i understand how to add set attributes for elements but i do not see how to set attrabutes for Nodes. I am trying to set some attributes for my very first node in the document.
Thanks

Hi,
First I'll make a correction to your concept that very first in XML document is a node.
Actually, node is a generic concept in XML DOC. Every thing including attribute, element, and document itself is a node. From implementation perspective if you study the documentation of XML Document object Model of Microsoft, you will find that a NODE actually is base class(interface) for every other xml construct e.g. element, attrubute, document.
Now you want to set attribute of a node, so in C++ you will do the following;
IXMLDOMNode* pNode;
// Set pNode to a valid reference of some node
// Now cast it to IXMLDOMElement
IXMLDOMElement* pElement;
pNode->QueryInterface(IID_IXMLDOMElement, (void**)&pElement);
// Now you can use "pElement" to add an attribte

Wow, thanks... I was not aware before of how the QueryInterface was used... but this makes sense.
So if i have multiple elements, would i have to do this for each one?

Hi,
Thanx for appreciation, first I will make correction to first sentence of my last message. It is "every thing(construct) e.g. element, comment, attribute, and document itself is a node". I am sorry for that.
Now come to your question, yes you have to do the same thing for all elements, but if you have elements of the same name then you can do it like this.
CComPtr<ixmldomdocument> pDoc;
CComPtr<ixmldomnodelist> pNodeList;
long nCount;
pDoc->getElementsByTagName(_bstr_t(_T("element_name")), &pNodeList);
pNodeList->get_length(&nCount);
for (long i = 0; i < nCount; i++)
{
CComPtr<ixmldomnode> pNode;
CComPtr<ixmldomelement> pElement;
pNodeList->get_item(_variant_t(i), &pNode);
pNode->QueryInterface(IID_IXMLDOMElement, (void*)&pElement);
// Do your own struff for this particular element
}
Regards,
Adeel Saqib

i wrote this code about the Matrix project here is a part of the code to input the matrix or a vector with a dynamic allocation:
double*vector ; int num ;
cout<<"enter the size of the vector"<<\n;
cin>>num;
vector=new double[num];
for(i=0;i{
cout<<"enter the element"<<i+1<<"in the="" vector"<<\n;
cin="">>*(vector+i)
}
this for input the vector but for input the matrix i made it in another function:
double*grade ; double**matrix ; int row ; int col;
cout<<"enter the number of rows then coloumns in the matrix"<<\n;
cin>>row>>col;
double**matrix=new double*[row];
for(int j=0;j{
matrix[j]=new double[col]
for(int k=0; k{
for( int l=0; l{
cout<<"enter the element"<<l+1<<"in the="" row"<<k+1<<\n;
cin="">>*(grade[k]+l)
}}}
iwant to ask of there is any missing in the followin part of the code
so may you answer these previous questions?
& is this pretag right?

No, the <pre> and </pre> tags need to surround the code. Before posting, click the Preview button.
See here for an example of a multi-dimensional array.

hiho@ll
i'm working on a browser helper object and i need to change the http header before a website is called
