You could modify the Draw() function in CGraphDataSet to do what you want. You can also look at other samples...

here:
http://www.codeproject.com/miscctrl/pgllib.asp[^][^]
There are an instructions:

1 Install GDI+ (part of Microsoft SDK).
2 Download Gdiplus.dll and make sure it is in the path,
3 Recompile the source, it will build .lib in the lib directory and the .dll in the bin directory
4 Add the directory with PGL binaries to your path. (by default it is C:\Program Files\PGL\bin)
5 Add the include directory and lib directory to Visual C++ include/lib directories.
6 Make sure the headers are available

I dont really understand them
I downloaded the GDI dll but I dont understand which path(in 2).
which source(in 3)?
How can I recompile him?
4 I dont understand too 5 and 6

After that they want me to make the variable ULONG_PTR m_ulGdiplusToken; in the CWinApp-is this class is the Dialog class?
I mean if I made a dialog based project.
Because when I have tried to find this class I haven't found..
Thank you all for your wonderful answers!

You just need to make sure the app can find the dll. Put it in windows/system32 or along with the app.

The source that comes with the article...

In your project settings add the path to the PGL headers to the Additional Include Directories under C/C++.

Add the lib directory under Linker/General. Add the .lib file to Additional Dependencies.

Semion_N wrote:

No. This is the CWinApp derived class, usually named CXXXApp located in XXX.cpp where XXX is the name of your project.

These are pretty basic questions, it might be prudent that you go and get yourself a book on MFC otherwise you would find it difficult to continue.

You are supposed to build the .lib file from the source provided, and set whatever path you want to put the .lib file in.

I think I can't "see" your posted code completely. I guess the format string contained some HTML tags? One option would be to use an XML DOM like MSXML or something. That is an extreme improvement from string concatenation and formating.

(fied above post)

XML DOM is better only in some cases, I've tried a bit (rather, with the IE5 DOM, but the game is the same, isn't it?).

I frequently end up having to build some HTML, often the XML DOM feels heavy (though acceptable), and I usually end up rolling my own very specializred functions. Trying to generalize these, the interface always gets very convoluted, so I woukld at least like to see others ideas

Don't know what that means, example?

I have used DOM's for years to generate HTML and never had a problem. Acutally it's 2006 wouldn't you generate XHTML anyway. A DOM is little more than a tree structure that handles syntax for XML which is exactly what you need to generate HTML anyway right? I'm confused.

can't add elements in the column

Hi i've strange problem.i've 4 columns Account,date,amount,address in a Clist Control.
//a breif abt my project

in my project am trying to slect a file by browsing (i used cfiledialog). & then pressing the button 'showbutton' i want to see all the documents(i.e.account,date,amount,address) of that file.this file is actually a list of several transaction.........

now in this project i didn't use classwizard, all the message mapping,dialog creation i've done mannually...............

//the problem

now, the problem is, while am trynig to insert items in the r8 column, only the 1st column is being populated , not the others....in the insertion column

CString strItem;
LVITEM lvi;
lvi.mask = LVIF_TEXT;

//Account no...
strItem.Format(_T(&TP->TR.Account[1]));
lvi.iSubItem = 0;
lvi.pszText = (LPTSTR)(LPCTSTR)(strItem);
m_cListCtrl.InsertItem( &lvi);

//Expirary Date
strItem.Format(_T(&TP->TR.ExpDate[1]));
lvi.iSubItem = 1;
lvi.pszText = (LPTSTR)(LPCTSTR)( strItem);
m_cListCtrl.InsertItem( &lvi);

nd this way only putting "lvi.iSubItem=2,3...4"

Don't get confused with TP,TR...these r my project variables for other issues.

using that above code.. am getting only 1st column....

waiting for quick reply.....A GOOD DAY to all.

The _T() macro is only needed with string literals. Also, why use the Format() method when you can assign &TP->TR.Account[1] directly to strItem?

Try:

int nItem = m_cListCtrl.InsertItem(0, &TP->TR.Account[1]);
m_cListCtrl.SetItemText(nItem, 1, &TP->TR.ExpDate[1]);

&TP->TR.Account[1] returns the string literal.so be sure that it's not making any problem. nd i used SetItemText as well as the SetItem both function.

Hi,
here is my example without lvItem structure:

<br />
// this works!<br />
                 i -> my linenumber and 1 is the first subitem!   <br />
ctrlList->SetItem(i, 1, LVIF_TEXT, MyTextHere, 0,NULL, NULL, 0);<br />
// i dont try this, but you can do this!<br />
//you can change to <br />
lvItem.iSubItem = 1;<br />
ctrlList.Setitem(&lvItem);<br />

i hope that helps!
regards

you should set the itemidentifier for the subitem, subitem must to know to witch item is to add!?

i solve your problem like this:

<br />
// one lvItem only for SubItems<br />
LVITEM lvItem;<br />
lvItem.iItem = 0; // this is important!!! can be any linenumber from your listctrl!<br />
lvItem.iSubItem = 1; // first subitem<br />
lvItem.mask = LVIF_TEXT;<br />
<br />
// example for iterating:<br />
int i = 0;<br />
while(i < 10)<br />
{<br />
// listctrl have only two columns!<br />
// Set Subitems Text to 10 Items!<br />
lvItem.iItem = i; // first item(first line in the listctrl)<br />
//lvItem.iSubItem = 1; // first subitem, stay the same, we dont need to change them here!<br />
lvItem.pszText = (LPTSTR)(LPCTSTR) NewText;<br />
listCtrl->SetItem(&lvItem);<br />
i++;<br />
}<br />
<br />

i try this and it works!
regards

maybe he does not know that a HD will have its capacity reduced after being formatted ?

that the advertised 40GB will really be 37.2GB AFTER formatting.
